Common Design Principles

  1. Add-on design: The existing treatment plan is not changed, discontinued, or reduced. The original treatment plan must have been stable for at least 4 weeks before enrollment.
  2. Positioned as supplementary nutritional support: Chienomoto is a food and is not to be evaluated as a therapeutic drug. We recommend setting primary endpoints in dimensions such as symptom burden, functional status, QOL (quality of life), and caregiver burden.
  3. Observation period: Typically 12 weeks (assessed at weeks 0/4/8/12). 24 weeks is recommended for cognitive endpoints. Symptom-burden endpoints (fatigue, sleep, hot flashes, etc.) may use 8 weeks.
  4. Safety assessment is mandatory: Includes recording of adverse events, adherence, dose changes in existing treatment, and worsening events of the underlying condition. Safety data alone can become an independent publication.
  5. Sample size: n=30–60 is recommended for exploratory studies. For randomized controlled trials, n≥30 per arm. Without research funding, we recommend not exceeding 120 cases at a single site.

Product Line & Indications

Chienomoto products are classified by age group and ingredient family. The PS family (No. 1, No. 2, No. 4) leans toward mood, sleep, and behavioral symptoms; the PQQ family (No. 3, No. 5) leans toward attention, memory, fatigue, and arousal. When selecting a topic, first determine which age group your target patients belong to, then decide what to observe.

Product No.Main ingredientsApplicable ageIndicated symptoms

Dosage & Administration

Please state the intervention dose in the protocol according to the table below. If dose adjustment is needed during the study period, the adjustment rules must be defined in the protocol in advance, and records must be kept.

Product No.Dosage & administration
No. 11 sachet daily
No. 2Ages 3–10: 1 sachet morning and evening
Age 11+: 2 sachets morning and evening, reduce as appropriate after improvement
No. 3Ages 3–10: 1 sachet morning and evening
Age 11 through adult: 2 sachets morning and evening, reduce as appropriate after improvement
No. 42–3 times daily, 2 sachets per dose, reduce as appropriate after symptom relief
No. 5For adults, 2–3 times daily, 2 sachets per dose. May be administered via nasal tube (pediatric dosing should follow physician instructions)

Core Outcome Measure Set

In addition to the specialized scales for each direction, we recommend also measuring the following core scales in common. The full set takes about 10–15 minutes to complete, and most are self-report or family-report. This allows small single-site studies to grow into a pooled multi-site analysis, with participants included as co-authors.

DomainAdultPediatric / Adolescent
MoodHADSSCARED + DSRS-C
SleepPSQI or ISICSHQ
Cognition / AttentionMoCA + PDQ-5-DBRIEF (parent form)

Developmental Disorders

Infancy through adolescence · 14 directions

This is the domain where Chienomoto can differentiate itself most. The core issue is not improving the core symptoms themselves, but that there is no long-term medication for comorbid burdens (mood, sleep, attention, executive function), and parents have strong anxiety about long-term medication. We recommend setting the primary endpoint on comorbid symptoms and family burden rather than core symptoms. This domain spans three product lines: No. 1 (ages 1–3), No. 2 (age 3+, mood/sleep/hyperactivity), and No. 3 (attention/memory/fatigue).

D1Early intervention support for language / global developmental delay, ages 1–3Ages 12–36 months, delay in language or global development (suggested by delay on the Gesell language domain or S-S method), with hearing loss and clear genetic/metabolic disease excluded. Currently receiving or about to start early intervention training. n=30–50Infant developmentNo. 1Level APriority
Population
Ages 12–36 months, delay in language or global development (suggested by delay on the Gesell language domain or S-S method), with hearing loss and clear genetic/metabolic disease excluded. Currently receiving or about to start early intervention training. n=30–50
Primary endpoint
24-week change in the Gesell Developmental Schedule language domain developmental index
Secondary endpoints
Adaptive, personal-social, and fine/gross motor domains; CDI infant language questionnaire vocabulary count; sleep; feeding; parenting stress (PSI-SF)
Safety endpoints (important)
Growth curve (height, weight, head circumference), feeding and elimination status, adverse events
Design
Parallel control with "early intervention training only," 24 weeks
Publication angle
Ages 1–3 are a critical period for language and neurodevelopment, but very few supportive options exist for this age group. Either a developmental clinic or rehabilitation department can lead; since children are already attending regular visits and training, follow-up adherence is very high

This is currently the only applicable age range for the No. 1 product. Safety and growth monitoring in this young age group must be rigorous, and we recommend the protocol be jointly reviewed by our medical department and specialists.

D2Early follow-up cohort for neurodevelopmental high-risk infantsAges 12–36 months, preterm birth (<34 weeks), low birth weight, history of hypoxic-ischemic encephalopathy or neonatal brain injury, with Gesell or Bayley suggesting developmental delay or borderline delay. n=40–60Infant developmentNo. 1Level A
Population
Ages 12–36 months, preterm birth (<34 weeks), low birth weight, history of hypoxic-ischemic encephalopathy or neonatal brain injury, with Gesell or Bayley suggesting developmental delay or borderline delay. n=40–60
Primary endpoint
Bayley-III or Gesell cognitive, language, and motor domain developmental indices
Secondary endpoints
BISQ infant sleep questionnaire, CBCL 1.5–5 emotional/behavioral, feeding status, parenting stress
Safety endpoints (important)
Growth curve, adverse events
Design
Prospective cohort + parallel control, 24 weeks. Continued cohort follow-up to age 3 is recommended
Publication angle
High-risk infant follow-up clinics already have an established visit rhythm and assessment structure, so the marginal cost of data collection is extremely low. If the cohort can be followed to age 3 for outcome assessment, the value doubles
D3Adjunct intervention for partial response / intolerance to ADHD medicationAges 6–16, on standard treatment with methylphenidate or atomoxetine for 4+ weeks at a stable dose, SNAP-IV still moderate or higher; or cases requiring dose reduction due to decreased appetite, insomnia, or mood rebound. n=40–60Cognition, attention & fatigueNo. 3Level A
Population
Ages 6–16, on standard treatment with methylphenidate or atomoxetine for 4+ weeks at a stable dose, SNAP-IV still moderate or higher; or cases requiring dose reduction due to decreased appetite, insomnia, or mood rebound. n=40–60
Primary endpoint
Change in SNAP-IV parent-rated total score at 12 weeks
Secondary endpoints
BRIEF executive function, CSHQ sleep, appetite and weight change, change in primary medication dose, CGI-I
Design
Open-label self-controlled pre/post, or non-randomized parallel control with "original treatment only," 12 weeks
Publication angle
Partial response and the dose-reduction dilemma are among the most common yet least-studied real-world scenarios in domestic ADHD clinics
D4Adjunct intervention for ADHD-comorbid sleep disorderAges 6–14 with ADHD, CSHQ total score ≥41 (suggesting sleep problems), stable treatment plan. n=40–60Pediatric mood & sleepNo. 2Level A
Population
Ages 6–14 with ADHD, CSHQ total score ≥41 (suggesting sleep problems), stable treatment plan. n=40–60
Primary endpoint
CSHQ total score and sleep-onset latency subscale
Secondary endpoints
Sleep diary (bedtime, number of night wakings), next-day SNAP-IV attention subscale, parent-rated sleep quality
Design
Open-label pre/post control or randomized control, 8–12 weeks
Publication angle
Sleep problems in ADHD are bidirectionally linked with stimulant use and are the single biggest factor undermining parental medication adherence. Domestic data are scarce
D5Transition support for ADHD "medication holidays" (summer/winter break drug-free periods)ADHD children who habitually stop or reduce medication during long school breaks. n=40–60Pediatric mood & sleepNo. 2Level APriority
Population
ADHD children who habitually stop or reduce medication during long school breaks. n=40–60
Primary endpoint
SNAP-IV and frequency of emotional outbursts during the medication holiday
Secondary endpoints
Weight catch-up, sleep, parent-child conflict frequency, smoothness of medication resumption after school restarts
Design
Randomized to "medication holiday + Chienomoto" vs. "medication holiday only," 8 weeks (covering the whole break)
Publication angle
Feasibility is extremely high — the recruitment window is concentrated, the follow-up period completes naturally, and parental motivation is very strong. In addition, "management of medication holidays" has been almost entirely unstudied in Japan
D6Cognitive Disengagement Syndrome (CDS / SCT) — inattentive-type hypoarousal and daytime sleepinessAges 8–16, with ADHD inattentive-type or borderline attention problems, prominent daydreaming, slow movement, sluggish responses, and daytime sleepiness that sCognition, attention & fatigueNo. 3Level APriority
Population
Ages 8–16, with ADHD inattentive-type or borderline attention problems, prominent daydreaming, slow movement, sluggish responses, and daytime sleepiness (positive on the Barkley SCT scale), regardless of concurrent stimulant treatment. n=40–60
Primary endpoint
Barkley Cognitive Disengagement Syndrome Scale (SCT/CDS parent form) total score
Secondary endpoints
ESS child sleepiness, SNAP-IV attention subscale, BRIEF executive function, teacher rating of classroom behavior, CPT reaction time and variability
Design
Open-label pre/post control or randomized control, 12 weeks
Publication angle
CDS is the most closely watched new concept in child psychiatry internationally over the past 5 years (renamed from SCT); it is partly independent of ADHD and responds poorly to stimulants — precisely the "medication doesn't work" population. Domestic clinical research is nearly nonexistent, making this one of the most novel directions on this list
D7Irritability and emotional outbursts in Autism Spectrum Disorder (ASD)Ages 3–12 with ASD, ABC Irritability subscale ≥18 or emotional outbursts ≥3 times/week, not on antipsychotics or on a stable dose. n=30–50Pediatric mood & sleepNo. 2Level A
Population
Ages 3–12 with ASD, ABC Irritability subscale ≥18 or emotional outbursts ≥3 times/week, not on antipsychotics or on a stable dose. n=30–50
Primary endpoint
ABC Irritability subscale (ABC-I)
Secondary endpoints
ARI Affective Reactivity Index, outburst frequency diary, parenting stress scale (PSI-SF), CGI-I
Design
Open-label pre/post control, 12 weeks
Publication angle
First-line medications for irritability in ASD (risperidone/aripiprazole) carry prominent metabolic side effects and strong parental resistance. The clinical need for a non-pharmacological adjunct is clear
D8Sleep disorders in ASDAges 3–12 with ASD, CSHQ ≥41 or sleep-onset latency >30 minutes. n=30–50Pediatric mood & sleepNo. 2Level A
Population
Ages 3–12 with ASD, CSHQ ≥41 or sleep-onset latency >30 minutes. n=30–50
Primary endpoint
CSHQ total score
Secondary endpoints
Sleep diary, actigraphy (if available at the site), daytime behavioral problems, parental sleep and mood
Design
Open-label pre/post control, or randomized control against standard sleep-hygiene education, 8–12 weeks
Publication angle
Options beyond melatonin are extremely limited. Being able to make parental sleep improvement a shared endpoint is a bonus
D9Adjunct intervention for pediatric epilepsy comorbidity (mood / sleep / cognition)Ages 4–16, confirmed epilepsy diagnosis, anti-seizure medication (ASM) regimen stable for 3+ months, seizure control stable over the past 3 months, withPediatric mood & sleepNo. 2Level APriority
Population
Ages 4–16, confirmed epilepsy diagnosis, anti-seizure medication (ASM) regimen stable for 3+ months, seizure control stable over the past 3 months, with a chief complaint of mood, sleep, or cognitive issues. n=40–60
Primary endpoint
Cognition (digit span + trail-making, or a brief Wechsler form) and BRIEF executive function
Secondary endpoints
SCARED/DSRS-C mood, CSHQ sleep, QOLCE quality of life, caregiver burden
Safety endpoints (important)
Seizure frequency change, ASM blood levels (if routinely monitored at the site), ASM dose adjustments — must be clearly defined and recorded throughout
Design
Open-label pre/post control, 12–24 weeks. An "ASM only" control arm strengthens the case
Publication angle
Epilepsy comorbidity is a recognized clinical gap in Japan, and "safety of a supplementary food product in children with epilepsy" can itself become an independent publication
Notes
The safety design for this direction must be rigorous, and we recommend the protocol be jointly reviewed by our medical department and specialists
D10Adjunct intervention for Tic Disorder (TD) comorbid with ADHD / obsessive-compulsive symptomsAges 6–16 with chronic tic disorder or Tourette syndrome, stable treatment plan. n=30–50Pediatric mood & sleepNo. 2Level A
Population
Ages 6–16 with chronic tic disorder or Tourette syndrome, stable treatment plan. n=30–50
Primary endpoint
YGTSS total score
Secondary endpoints
Comorbid ADHD symptoms (SNAP-IV), obsessive-compulsive symptoms (CY-BOCS), sleep, CGI-I
Design
Open-label pre/post control, 12 weeks
Publication angle
Because tic disorders fluctuate substantially, we recommend extending the baseline observation period by 2–4 weeks to control for natural variability. This design refinement can itself be a methodological highlight
D11Adjunct support during intensive rehabilitation for global developmental delay / language delayAges 2.5–6 with GDD/language delay, receiving systematic rehabilitation training 3+ times weekly. n=30–50Pediatric mood & sleepNo. 2Level A
Population
Ages 2.5–6 with GDD/language delay, receiving systematic rehabilitation training 3+ times weekly. n=30–50
Primary endpoint
Gesell Developmental Schedule or GDS language/adaptive domain
Secondary endpoints
S-S language development assessment, engagement rating during training (therapist-rated), sleep, caregiver burden
Design
Parallel control with "rehabilitation training only," 12–24 weeks
Publication angle
Easiest to implement in rehabilitation medicine — children are already attending training multiple times a week, so follow-up cost is near zero and attrition is extremely low
Notes
The lower age bound must match the product's applicable age range; confirm with us before enrollment
D12Training tolerance and fatigue during intensive rehabilitation in children with developmental disordersAges 2.5–8 with GDD/ASD/cerebral palsy, receiving intensive rehabilitation training 3+ times weekly, with therapists reporting "engagement drops qCognition, attention & fatigueNo. 3Level A
Population
Ages 2.5–8 with GDD/ASD/cerebral palsy, receiving intensive rehabilitation training 3+ times weekly, with therapists reporting "engagement drops quickly in the second half of the session." n=30–50
Primary endpoint
Effective participation time per training session (stopwatch-timed by the therapist, objective and cost-free) + PedsQL Multidimensional Fatigue Scale (parent form)
Secondary endpoints
Training engagement rating, training completion rate, parent-observed post-training fatigue, sleep, Gesell/GDS developmental domains
Design
Parallel control with "rehabilitation training only," 12 weeks
Publication angle
"Training tolerance" is the ceiling on rehabilitation volume — training volume determines outcome, and fatigue determines training volume. No one has systematically studied this causal chain, yet every rehabilitation therapist feels it, and it resonates strongly with specialists

Positioning of this domain: Antidepressants can resolve core mood symptoms, but residual symptoms (cognition, sleep, fatigue, somatization) are the main drivers of relapse and incomplete functional recovery, for which pharmacological options are limited. This is Chienomoto's primary battleground.

D13Sustained attention and academic performance in school-age children with learning disability / weak executive functionAges 8–14, normal intelligence, with reading/writing/math difficulty or executive function complaints, not meeting criteria for an ADHD diagnosis. n=40–60Cognition, attention & fatigueNo. 3Level A
Population
Ages 8–14, normal intelligence, with reading/writing/math difficulty or executive function complaints, not meeting criteria for an ADHD diagnosis. n=40–60
Primary endpoint
BRIEF executive function total score + continuous performance test (CPT, if available)
Secondary endpoints
Academic self-rating, teacher rating, mood and sleep
Design
Randomized control (waitlist control), 12 weeks
Publication angle
This borderline population is easy to recruit from, and suits interdisciplinary education-medicine journals
D14Caregiver burden, mood, and sleep in caregivers of children with developmental disorders (**caregivers as subjects**)Primary caregivers (mostly mothers) of children with ADHD/ASD/GDD, PSI-SF or ZBI suggesting moderate-to-severe burden. n=40–60Adult mood & behavioral healthNo. 4Level A
Population
Primary caregivers (mostly mothers) of children with ADHD/ASD/GDD, PSI-SF or ZBI suggesting moderate-to-severe burden. n=40–60
Primary endpoint
Caregiver burden scale (PSI-SF / ZBI)
Secondary endpoints
Caregiver PHQ-9, GAD-7, PSQI, family functioning (FAD)
Design
Open-label pre/post control or randomized control, 12 weeks
Publication angle
Shifting the lens to caregivers means very little competition. Acceptance rates are high in nursing and psychology journals, and enrollment is extremely fast (caregivers themselves are highly motivated, and follow-up adherence is far higher than for the child patients)

Mood Disorders

Depression · Anxiety · Bipolar disorder · 13 directions

Antidepressants can resolve core mood symptoms, but residual symptoms (cognition, sleep, fatigue, somatization) are the main drivers of relapse and incomplete functional recovery, for which pharmacological options are limited. This is Chienomoto's primary battleground.

M1Adjunctive improvement of residual cognitive symptoms (executive function) in depressionAges 18–60, MDD, antidepressant stable for 8+ weeks, HAMD-17 ≤10 (clinical remission or partial remission), but with a subjective cognitive complaint (PDQ-5-D above cutoff). n=50–80Cognition, attention & fatigueNo. 3Level BPriority
Population
Ages 18–60, MDD, antidepressant stable for 8+ weeks, HAMD-17 ≤10 (clinical remission or partial remission), but with a subjective cognitive complaint (PDQ-5-D above cutoff). n=50–80
Primary endpoint
12-week change in THINC-it composite score or DSST (Digit Symbol Substitution Test)
Secondary endpoints
PDQ-5-D subjective cognition, TMT-A/B, HAMD-17, SDS functional impairment scale, return-to-work/school status
Design
Randomized double-blind placebo-controlled (first choice) or open-label control, 12 weeks
Publication angle
Residual cognitive symptoms are an international hot topic (CANTAB/THINC-it have become standard tools), and domestic non-pharmacological intervention data are extremely scarce. The subjective-objective cognition divergence is an analytical angle that readily yields findings
M2Reduced motivation and anhedonia in depression (apathy dimension)Ages 18–60, MDD, antidepressant stable for 8+ weeks, HAMD shows partial remission but with prominent "no interest, no motivation, no energy," AES ≥34 or SHCognition, attention & fatigueNo. 3Level APriority
Population
Ages 18–60, MDD, antidepressant stable for 8+ weeks, HAMD shows partial remission but with prominent "no interest, no motivation, no energy," AES ≥34 or SHAPS suggesting anhedonia. n=40–60
Primary endpoint
AES Apathy Evaluation Scale or SHAPS anhedonia scale
Secondary endpoints
TEPS anticipatory/consummatory pleasure, Behavioral Activation for Depression Scale (BADS), HAMD (adjusted as covariate), SDS functional impairment, return-to-work/school status
Design
Open-label pre/post control or randomized control, 12 weeks
Publication angle
Anhedonia and reduced motivation are the dimensions of depression least overcome by antidepressants (SSRIs may even worsen them), and they directly contribute to incomplete functional recovery. Framing "apathy improvement as independent of mood-symptom improvement" as the analytic core adds academic weight
M3SSRI-associated emotional blunting and pharmacogenic apathyAges 18–55, MDD, on SSRI treatment with mood symptoms in remission, but reporting "my emotions feel flat, I don't feel happy or sad, nothing matters anCognition, attention & fatigueNo. 3Level APriority
Population
Ages 18–55, MDD, on SSRI treatment with mood symptoms in remission, but reporting "my emotions feel flat, I don't feel happy or sad, nothing matters anymore." n=40–60
Primary endpoint
OQESA (Oxford Questionnaire on the Emotional Side-effects of Antidepressants)
Secondary endpoints
AES apathy, SHAPS, sexual function and other SSRI side effects, self-directed SSRI discontinuation rate and adherence, HAMD (confirming no worsening)
Design
Open-label pre/post control or randomized control, 12 weeks
Publication angle
This is a significantly underrecognized clinical problem — reported rates of emotional blunting reach 40–60%, making it one of the top reasons patients self-discontinue medication, yet effective interventions are almost nonexistent. Making "discontinuation rate" a shared primary endpoint directly links symptom improvement to relapse prevention. Domestic research is nearly a blank slate, and personally I consider this one of the directions on this list with the greatest potential to draw sudden attention
M4Fatigue and residual somatic symptoms in depressionAfter MDD treatment, HAMD in remission but with prominent fatigue/low energy. n=40–60Cognition, attention & fatigueNo. 3Level A
Population
After MDD treatment, HAMD in remission but with prominent fatigue/low energy. n=40–60
Primary endpoint
FSS fatigue severity or MFI-20
Secondary endpoints
PHQ-15, SDS function, work productivity (WPAI)
Design
Open-label pre/post control, 12 weeks
Publication angle
Fatigue is the most common yet least-measured residual symptom, and it is directly linked to relapse risk
M5Antidepressant-associated daytime fatigue and sedationPatients on strongly sedating antidepressants such as mirtazapine, paroxetine, or trazodone, reporting daytime fatigue and grogginess. n=40–60Cognition, attention & fatigueNo. 3Level A
Population
Patients on strongly sedating antidepressants such as mirtazapine, paroxetine, or trazodone, reporting daytime fatigue and grogginess. n=40–60
Primary endpoint
FSS fatigue severity or MFI-20
Secondary endpoints
ESS sleepiness, daytime function (WPAI work efficiency), rate of antidepressant dose reduction or switching, HAMD (confirming no worsening), medication adherence
Design
Open-label pre/post control, 12 weeks
Publication angle
Drug-induced fatigue is a classic scenario of "the illness resolved but life fell apart," and it is also a leading cause of medication switching or discontinuation. The framing of managing an adverse drug reaction is logically clean and ethically simple

Positioning of this domain: This is the domain with the deepest data accumulation among Japan-originated products, and it is also the easiest domain to enroll from in domestic memory clinics. We recommend emphasizing both ends of the spectrum — early stage (SCD/MCI) and BPSD/caregiver burden — as the two main thrusts: the former offers large sample sizes and fast recruitment, the latter presents the sharpest clinical challenge.

M6Adjunct intervention for insomnia accompanying depressionAges 18–65, MDD with insomnia, ISI ≥15, stable antidepressant regimen. n=40–60Adult mood & behavioral healthNo. 4Level A
Population
Ages 18–65, MDD with insomnia, ISI ≥15, stable antidepressant regimen. n=40–60
Primary endpoint
ISI Insomnia Severity Index
Secondary endpoints
PSQI, sleep diary, change in sleep medication (including benzodiazepines/Z-drugs) use, HAMD sleep factor, daytime fatigue
Design
Open-label pre/post control or randomized control, 8–12 weeks
Publication angle
Set "sleep medication tapering" as a shared primary endpoint — de-benzodiazepine efforts are a current direction in both domestic policy and clinical practice, and this framing substantially raises the value of the paper
M7Support during the 4–6 week SSRI onset "window period" in adolescent depressionAges 12–18, MDD, within 7 days of starting an SSRI. n=50–80Pediatric mood & sleepNo. 2Level B
Population
Ages 12–18, MDD, within 7 days of starting an SSRI. n=50–80
Primary endpoint
HAMD/CDI change trajectory over the first 6 weeks, and "time to onset of effect"
Secondary endpoints
ARI irritability, agitation/restlessness, sleep, NSSI behavior frequency, early SSRI discontinuation rate
Safety endpoints
Activation syndrome and change in suicidal ideation (C-SSRS) must be monitored throughout
Design
Randomized control (SSRI + Chienomoto vs. SSRI), 6–12 weeks
Publication angle
The window before an SSRI takes effect is the period of highest risk in adolescent depression, and also the period with the highest attrition — yet intervention research here is nearly absent
Notes
Because this population carries suicide risk, ethical requirements are high; we recommend limiting this direction to sites with adolescent psychiatric wards and crisis-response protocols
M8Emotion-regulation support for non-suicidal self-injury (NSSI) in adolescent depressionAges 12–18 with NSSI behavior, on standard treatment. n=30–50Pediatric mood & sleepNo. 2Level B
Population
Ages 12–18 with NSSI behavior, on standard treatment. n=30–50
Primary endpoint
NSSI behavior frequency (self-injury log / OSI)
Secondary endpoints
DERS Difficulties in Emotion Regulation Scale, ARI irritability, impulsivity (BIS-11), sleep
Design
Open-label pre/post control, 12 weeks
Publication angle
NSSI is currently one of the most closely watched topics in adolescent psychology, and an emotion-regulation-mechanism angle offers more depth than a purely symptom-based angle
Notes
This is a high-risk population, so requirements for ethics and safety-response protocols are high
M9Residual cognitive impairment and circadian rhythm disruption during bipolar disorder remissionAges 18–55, BD-I/II in remission (YMRS ≤7 and HAMD ≤8 sustained for 8+ weeks), stable mood-stabilizer regimen. n=40–60Cognition, attention & fatigueNo. 3Level BPriority
Population
Ages 18–55, BD-I/II in remission (YMRS ≤7 and HAMD ≤8 sustained for 8+ weeks), stable mood-stabilizer regimen. n=40–60
Primary endpoint
24-week change in cognition (brief MCCB, or digit symbol + TMT + verbal fluency)
Secondary endpoints
BRIAN circadian rhythm scale, PSQI, FAST functioning assessment, quality of life
Safety endpoints (important)
YMRS and ASRM must be monitored throughout for manic-switch risk, with mood episodes logged individually
Design
Open-label pre/post control, 24 weeks (cognitive endpoints require longer observation)
Publication angle
Cognitive impairment during bipolar remission is central to incomplete functional recovery, with no effective medication available. In addition, safety data showing that "a supplementary supplement does not trigger manic switching" has independent value on its own
Notes
Manic-switch risk is the single greatest scientific and compliance risk in this direction, and the protocol must include clear discontinuation criteria
M10Adjunct intervention for cognitive decline in late-life (late-onset) depressionDepressive disorder in patients age 60+, GDS-15 ≥8, MoCA 18–25 (suggesting mild cognitive impairment), stable antidepressant regimen. n=40–60Adult mood & behavioral healthNo. 4Level A
Population
Depressive disorder in patients age 60+, GDS-15 ≥8, MoCA 18–25 (suggesting mild cognitive impairment), stable antidepressant regimen. n=40–60
Primary endpoint
Dual endpoint of MoCA + GDS-15
Secondary endpoints
AVLT auditory verbal learning, daily function (IADL), sleep, fall events
Design
Open-label pre/post control, 24 weeks
Publication angle
Late-onset depression is a prodromal symptom of dementia, and the intervention window for the "depression-dementia continuum" is a recently prominent theme. Publishable from geriatrics, psychiatry, or neurology alike
M11Generalized anxiety disorder / anxiety with somatic symptomsAges 18–65, GAD or anxiety disorder, HAMA ≥14, stable regimen. n=40–60Adult mood & behavioral healthNo. 4Level A
Population
Ages 18–65, GAD or anxiety disorder, HAMA ≥14, stable regimen. n=40–60
Primary endpoint
HAMA total score (separable into somatic and psychic factors)
Secondary endpoints
GAD-7, PHQ-15 somatization, PSQI, change in benzodiazepine use
Design
Open-label pre/post control, 8–12 weeks
Publication angle
The somatic subtype of anxiety responds poorly to medication and is seen across scattered departments (gastroenterology, cardiology), making it an underrecognized population
M12Adjunct support during rTMS / MECT for treatment-resistant depressionDepression patients undergoing an rTMS course or MECT. n=30–50Cognition, attention & fatigueNo. 3Level B
Population
Depression patients undergoing an rTMS course or MECT. n=30–50
Primary endpoint
HAMD response rate at end of course / post-MECT cognitive recovery (MMSE, AVLT)
Secondary endpoints
Treatment-related adverse events (headache, memory impairment), sleep, course completion rate
Design
Randomized control, covering the full course + 4 weeks of follow-up
Publication angle
Nutritional protection against post-MECT cognitive impairment is a very novel angle, with very few people working on it domestically
M13Exploratory study of oxidative stress and inflammatory markers in depressionMDD patients, stable regimen. n=40–60Cross-domain combinationTBDLevel C
Population
MDD patients, stable regimen. n=40–60
Primary endpoint
Serum inflammation/oxidative stress markers (IL-6, hs-CRP, TNF-α, MDA, SOD, total antioxidant capacity)
Secondary endpoints

Mechanism-level correlation analysis is an important bonus for SCI publications, and can be combined with any clinical direction
A

Geriatric Dementia

The full spectrum of cognitive impairment · 12 directions

This is the domain with the deepest data accumulation among Japan-originated products, and it is also the easiest domain to enroll from in domestic memory clinics. We recommend emphasizing both ends of the spectrum — early stage (SCD/MCI) and BPSD/caregiver burden — as the two main thrusts: the former offers large sample sizes and fast recruitment, the latter presents the sharpest clinical challenge.

A1Cognitive maintenance and anxiety relief in Subjective Cognitive Decline (SCD)Age 55+, memory complaints with normal objective cognition (MoCA ≥26, CDR=0). n=60–100Cognition, attention & fatigueNo. 3Level APriority
Population
Age 55+, memory complaints with normal objective cognition (MoCA ≥26, CDR=0). n=60–100
Primary endpoint
SCD-Q / MAC-Q subjective cognitive questionnaire; objective memory (AVLT) as a shared endpoint
Secondary endpoints
HADS anxiety/depression, sleep, quality of life, cognition-related healthcare-seeking behavior
Design
Randomized control (control arm receives health education), 24 weeks
Publication angle
SCD is the largest and least-studied population in memory clinics, with enrollment speed far exceeding MCI/AD. The "subjective-objective divergence" analysis carries theoretical depth
A2Cognitive maintenance in Mild Cognitive Impairment (MCI)Age 55+, meets Petersen MCI criteria, MoCA 18–25, CDR=0.5. n=50–80Cognition, attention & fatigueNo. 3Level B
Population
Age 55+, meets Petersen MCI criteria, MoCA 18–25, CDR=0.5. n=50–80
Primary endpoint
24-week change in ADAS-Cog or MoCA
Secondary endpoints
AVLT delayed recall, TMT, daily function (FAQ), mood, sleep, conversion rate to dementia (long-term follow-up)
Design
Randomized control (open-label or double-blind), 24 weeks. Extended follow-up to 12 months is recommended
Publication angle
MCI intervention is a global hot topic. If the cohort can be retained through a 12-month conversion-rate follow-up, the value doubles
A3Add-on to cholinesterase inhibitor combination therapy in mild-to-moderate Alzheimer's diseaseMild-to-moderate AD, donepezil/memantine stable for 3+ months, MMSE 10–24. n=40–60Adult mood & behavioral healthNo. 4Level A
Population
Mild-to-moderate AD, donepezil/memantine stable for 3+ months, MMSE 10–24. n=40–60
Primary endpoint
ADAS-Cog (or MMSE)
Secondary endpoints
ADCS-ADL activities of daily living, NPI-Q, CDR-SB, caregiver burden (ZBI)
Design
Open-label self-controlled pre/post or parallel control, 24 weeks
Publication angle
Cognitive endpoints in AD rarely show significant change within 24 weeks, so we recommend setting ADL and NPI as shared primary endpoints — both success probability and clinical significance are higher
A4Behavioral and psychological symptoms of dementia (BPSD) — agitation, irritability, nighttime behaviorVarious dementias with BPSD, NPI-Q total score ≥6 or a prominent agitation subscale. n=40–60Adult mood & behavioral healthNo. 4Level APriority
Population
Various dementias with BPSD, NPI-Q total score ≥6 or a prominent agitation subscale. n=40–60
Primary endpoint
NPI-Q total score and agitation/irritability subscale
Secondary endpoints
CMAI agitation inventory, change in antipsychotic dose, caregiver burden (ZBI), risk of institutionalization
Design
Open-label pre/post control, 12 weeks
Publication angle
BPSD is the most distressing challenge in dementia care, and antipsychotics carry a black-box warning, with guidelines emphasizing non-pharmacological approaches first. Demonstrating "antipsychotic dose reduction" would be a very strong selling point for the paper
A5Apathy in dementiaMild-to-moderate AD, VCI, or PDD, prominent NPI apathy subscale or AES-I (caregiver form) ≥38, stable cholinesterase inhibitor regimen. n=40–60Cognition, attention & fatigueNo. 3Level APriority
Population
Mild-to-moderate AD, VCI, or PDD, prominent NPI apathy subscale or AES-I (caregiver form) ≥38, stable cholinesterase inhibitor regimen. n=40–60
Primary endpoint
AES-I Apathy Evaluation Scale (caregiver form) or NPI apathy subscale
Secondary endpoints
Engagement in daily activities (caregiver activity diary), ADCS-ADL, cognition (MoCA/ADAS-Cog), depression (CSDD Cornell Scale for Depression in Dementia, for differentiation), ZBI caregiver burden
Design
Open-label pre/post control, 12–24 weeks
Publication angle
Apathy is the most prevalent BPSD in dementia (50–70%), higher than agitation, yet one of the least studied — because it is "quiet," families rarely complain about it, and physicians rarely prescribe for it. Yet it directly determines whether a patient can engage in activities, socializing, and rehabilitation, and it is the deepest source of caregiver helplessness. Currently there is no approved treatment. This direction carries extremely high clinical value with very little competition
A6Sleep-circadian rhythm disruption and "sundowning" in dementia patientsDementia with nighttime awakening, day-night reversal, or evening agitation. n=30–50Adult mood & behavioral healthNo. 4Level A
Population
Dementia with nighttime awakening, day-night reversal, or evening agitation. n=30–50
Primary endpoint
Sleep diary (caregiver-recorded) total sleep time and number of night wakings; or actigraphy rhythm parameters
Secondary endpoints
Frequency of sundowning episodes, NPI nighttime behavior subscale, caregiver sleep and burden, sleep medication use
Design
Open-label pre/post control, 8–12 weeks
Publication angle
Sundowning directly determines whether a family can sustain home care and is the leading trigger for institutionalization, giving it extremely high clinical significance
A7Visual hallucinations, cognitive fluctuation, and REM sleep behavior disorder in Dementia with Lewy Bodies (DLB)Probable DLB, stable regimen. n=20–40 (case series acceptable given the rare-disease context)Adult mood & behavioral healthNo. 4Level A
Population
Probable DLB, stable regimen. n=20–40 (case series acceptable given the rare-disease context)
Primary endpoint
NPI hallucination subscale + cognitive fluctuation scale (CAF / MFC)
Secondary endpoints
RBDSQ, MoCA, UPDRS-III, fall events, antipsychotic hypersensitivity events
Design
Open-label pre/post control or prospective case series, 12–24 weeks
Publication angle
DLB patients are highly sensitive to antipsychotics (risking neuroleptic malignant syndrome), leaving treatment options extremely limited. Even an n=20 case series has publication value
A8Mild cognitive impairment (PD-MCI) / dementia in Parkinson's diseasePD with a cognitive complaint, MDS-criteria PD-MCI, stable anti-Parkinsonian regimen. n=40–60Cognition, attention & fatigueNo. 3Level A
Population
PD with a cognitive complaint, MDS-criteria PD-MCI, stable anti-Parkinsonian regimen. n=40–60

MoCA / PD-CRS Parkinson's Disease Cognitive Rating Scale
Secondary endpoints
MDS-UPDRS-I (non-motor symptoms), RBDSQ, PDSS-2 sleep, depression, quality of life PDQ-39
Design
Open-label pre/post control, 24 weeks
Publication angle
Non-motor symptoms of PD (cognition, sleep, mood) are the current mainstream direction of PD research, leaving substantial room beyond motor symptoms
A9Long-term management of Vascular Cognitive Impairment (VCI) / post-stroke cognitive impairmentVCIND or mild vascular dementia, 3+ months post-stroke, stable secondary-prevention regimen. n=40–60Arousal & neurorehabilitationNo. 5Level A

Primary endpoint
MoCA + executive function (TMT-B, Stroop)
Secondary endpoints
Mood/apathy, depression, daily function, recurrence events
Design
Open-label pre/post control, 24 weeks
Publication angle
VCI is primarily driven by executive dysfunction (distinct from the memory impairment of AD); choosing the right cognitive assessment tool is key to success
A10Prospective case series on behavioral symptoms in behavioral-variant frontotemporal dementia (bvFTD)Behavioral-variant FTD. n=15–30Adult mood & behavioral healthNo. 4Level A
Population
Behavioral-variant FTD. n=15–30
Primary endpoint
FBI Frontal Behavioral Inventory / NPI disinhibition and apathy subscales
Secondary endpoints
CBI-R, caregiver burden, cognition (frontal executive function)
Design
Prospective case series, 24 weeks
Publication angle
FTD has no approved treatment at all, and case series for rare diseases have a stable publication venue in specialty journals
A11Nutritional support for geriatric frailty and fatigueCommunity-dwelling or outpatient adults age 65+, FRAIL scale 1–3 (pre-frail/frail), with fatigue among the chief complaints. n=50–80Cognition, attention & fatigueNo. 3Level A
Population
Community-dwelling or outpatient adults age 65+, FRAIL scale 1–3 (pre-frail/frail), with fatigue among the chief complaints. n=50–80
Primary endpoint
FRAIL scale score or Fried frailty phenotype classification
Secondary endpoints
Grip strength, 4m gait speed, SPPB Short Physical Performance Battery, FSS fatigue, MNA-SF nutrition, falls and hospitalization events, cognition and mood
Design
Randomized control (control arm receives exercise + nutrition counseling), 24 weeks
Publication angle
Fatigue is one of the five core criteria in the Fried frailty phenotype, and frailty is currently one of the most closely watched areas in geriatric medicine, directly linked to functional decline, hospitalization, and mortality. It can be led by geriatrics, general medicine, or rehabilitation medicine, and published in both geriatric-medicine and clinical-nutrition journals

Positioning of this domain: Psychiatric inpatient/day-care wards are the research setting with the highest medication adherence and follow-up completion (patients are concentrated, medication can be supervised, and attrition is extremely low). We recommend focusing on negative symptoms, cognitive impairment, and tapering of sedating medications as the main thrusts.

Psychiatric inpatient/day-care wards are the research setting with the highest medication adherence and follow-up completion (patients are concentrated, medication can be supervised, and attrition is extremely low). We recommend focusing on negative symptoms, cognitive impairment, and tapering of sedating medications as the main thrusts.

P1Adjunct intervention for negative symptoms and cognitive impairment in schizophreniaAges 18–55, stable-phase schizophrenia, antipsychotic stable for 8+ weeks, PANSS negative scale ≥15. n=50–80Cognition, attention & fatigueNo. 3Level BPriority

Safety endpoints
Positive-symptom worsening events, hospitalization events
Design
Randomized control (open-label or double-blind), 12–24 weeks
Publication angle
Negative symptoms and cognitive impairment represent the greatest unmet need in schizophrenia, and are also central to social functioning. There is clear room for adjunct-intervention research in Japan
P2Avolition and anhedonia subdimensions in schizophreniaAges 18–55, stable-phase schizophrenia, antipsychotic stable for 8+ weeks, BNSS or CAINS showing prominent motivation-pleasure dimension impairment. nCognition, attention & fatigueNo. 3Level BPriority
Population
Ages 18–55, stable-phase schizophrenia, antipsychotic stable for 8+ weeks, BNSS or CAINS showing prominent motivation-pleasure dimension impairment. n=40–60
Primary endpoint
BNSS Brief Negative Symptom Scale "motivation-pleasure" factor, or CAINS-MAP
Secondary endpoints
MAP-SR self-rated motivation and pleasure, daily activity log (behavioral measure), PSP social functioning, PANSS negative scale, cognition
Design
Randomized control, 12–24 weeks
Publication angle
Negative symptoms have already been clearly separated into two independent factors — "diminished expression" and "diminished motivation-pleasure" — with the latter more predictive of functional outcome and less responsive to medication. Using next-generation tools like BNSS/CAINS instead of PANSS-N as the primary endpoint itself demonstrates methodological sophistication
P3Antipsychotic-associated sedation, daytime sleepiness, and functional impairmentPatients on strongly sedating antipsychotics such as quetiapine, clozapine, or olanzapine, with ESS ≥10 or reporting that daytime sleepiness affects fuArousal & neurorehabilitationNo. 5Level APriority
Population
Patients on strongly sedating antipsychotics such as quetiapine, clozapine, or olanzapine, with ESS ≥10 or reporting that daytime sleepiness affects functioning. n=40–60
Primary endpoint
ESS Epworth Sleepiness Scale
Secondary endpoints
FSS fatigue, daytime alertness (KSS at multiple time points), cognition (reaction time, sustained attention), self-directed antipsychotic discontinuation rate and adherence, PSP functioning, psychiatric symptoms (confirming no worsening)
Design
Randomized control, 12 weeks
Publication angle
Daytime sedation is the single biggest factor undermining antipsychotic adherence, and a direct barrier to returning to work and reintegrating socially. In clinical practice physicians usually have only two options: "switch medication or endure it." Making adherence a shared endpoint directly links it to relapse risk

Positioning of this domain: The subacute inpatient rehabilitation window (2 weeks to 3 months post-onset) in rehabilitation medicine is an ideal research setting — patients are hospitalized daily, assessment is completed routinely by therapists, and follow-up attrition is zero. We recommend prioritizing three directions with no effective medication: post-stroke cognition, fatigue, and apathy.

P4Overall symptoms and functioning during the rehabilitation phase in long-term hospitalized chronic schizophreniaChronic patients hospitalized 1+ year, stable regimen. n=50–80Adult mood & behavioral healthNo. 4Level APriority
Population

Primary endpoint
PANSS total score + PSP functioning
Secondary endpoints
Cognition, sleep, independence in daily living, nurse observation scale (NOSIE), weight and metabolic markers
Design
Randomized control, 24 weeks
Publication angle
The most feasible direction overall — medication can be supervised, follow-up attrition is zero, assessment is performed by ward nurses, and there is no risk of losing patients to follow-up. Well suited as a first joint project with a psychiatric specialty hospital
P5Protecting cognition and function during the early-intervention phase of First-Episode Psychosis (FEP)First episode, within 3 months of starting an antipsychotic, ages 18–35. n=40–60Cognition, attention & fatigueNo. 3Level B

Primary endpoint
24-week change in the MCCB cognitive battery
Secondary endpoints
PANSS, PSP, return-to-school/work rate, correlation analysis with DUP
Design
Randomized control, 24 weeks
Publication angle
The "cognitive trajectory" during the first episode is a central theme of early-intervention research worldwide
P6Sleep improvement and benzodiazepine tapering in psychiatric inpatientsHospitalized psychiatric patients on long-term benzodiazepine or Z-drug hypnotics, with intent to taper. n=40–60Adult mood & behavioral healthNo. 4Level BPriority
Population
Hospitalized psychiatric patients on long-term benzodiazepine or Z-drug hypnotics, with intent to taper. n=40–60
Primary endpoint
Reduction in benzodiazepine daily equivalent dose (diazepam equivalent)
Secondary endpoints
PSQI, ISI, tapering success rate, withdrawal-related symptoms, fall events, daytime sleepiness
Design
Randomized control (standard tapering protocol ± Chienomoto), 12 weeks
Publication angle
De-benzodiazepine efforts are a shared policy direction domestically and internationally, and linking an adjunct approach to tapering success rate is one of the strongest publication concepts on this list. Correlation analysis with fall risk in elderly patients adds further points
P7Exploratory study of antipsychotic-associated metabolic burden and oxidative stressPatients on higher metabolic-risk medications such as olanzapine/clozapine. n=40–60Cross-domain combinationTBDLevel C
Population

Secondary endpoints
Oxidative stress markers, inflammatory factors, psychiatric symptoms, quality of life
Design
Randomized control, 24 weeks
Publication angle
Mechanism-level exploration with high SCI-publication potential
Notes
This is an exploratory direction, and no advance claims about metabolic improvement should be made. The protocol wording must be handled carefully

Design
Open-label pre/post control, 12 weeks
Publication angle
OCD has a low response rate and high residual-symptom rate, yet adjunct-intervention research is limited

Secondary endpoints
WHOQOL-BREF, employment/school status, relapse and re-hospitalization rate, medication adherence
Design
Randomized control, 24 weeks
Publication angle
Functional outcomes align more closely with national mental-health policy direction than symptom outcomes do, making them well suited to public-health journals

Post-Stroke Rehabilitation

Including traumatic brain injury · 10 directions

The subacute inpatient rehabilitation window (2 weeks to 3 months post-onset) in rehabilitation medicine is an ideal research setting — patients are hospitalized daily, assessment is completed routinely by therapists, and follow-up attrition is zero. We recommend prioritizing three directions with no effective medication: post-stroke cognition, fatigue, and apathy.

S1Adjunct intervention built on standard rehabilitation for Post-Stroke Cognitive Impairment (PSCI)2 weeks–6 months after first stroke, MoCA <26, receiving cognitive rehabilitation training. n=50–80Arousal & neurorehabilitationNo. 5Level A
Population

Secondary endpoints
Executive function (TMT-B, Stroop), AVLT, MBI activities of daily living, mRS
Design
Randomized control (standard rehabilitation ± Chienomoto), 12–24 weeks
Publication angle
PSCI occurs in 30–60% of patients, yet guideline recommendations remain weak, making it the most mainstream research direction in rehabilitation medicine
S2Adjunct intervention for Post-Stroke Depression (PSD)1–6 months post-stroke, HAMD-17 ≥8 or PHQ-9 ≥5. n=40–60Adult mood & behavioral healthNo. 4Level A
Population

Primary endpoint
HAMD-17 or PHQ-9
Secondary endpoints
Engagement and cooperation with rehabilitation training, MBI, fatigue, sleep, rate of antidepressant initiation
Design
Randomized control, 12 weeks
Publication angle
PSD directly affects adherence to rehabilitation training. Setting "training engagement" as a secondary endpoint links mood improvement to functional recovery, making the logic more complete
S3Adjunct intervention for Post-Stroke Fatigue (PoSF)1+ months post-stroke, FSS ≥4 or FAS ≥22. n=40–60Cognition, attention & fatigueNo. 3Level APriority
Population
1+ months post-stroke, FSS ≥4 or FAS ≥22. n=40–60
Primary endpoint
FSS Fatigue Severity Scale
Secondary endpoints
Rehabilitation training tolerance time (objective measure), 6-minute walk distance, mood, sleep, quality of life
Design
Randomized control, 12 weeks
Publication angle
No effective medication currently exists for post-stroke fatigue, and guidelines can only recommend non-pharmacological approaches — one of the most "legitimately justified" indication scenarios for a functional food
S4Post-stroke apathy1–6 months post-stroke, AES suggesting apathy, requiring differentiation from depression. n=30–50Arousal & neurorehabilitationNo. 5Level A
Population
1–6 months post-stroke, AES suggesting apathy, requiring differentiation from depression. n=30–50
Primary endpoint
AES Apathy Evaluation Scale
Secondary endpoints
Proactivity in rehabilitation training (therapist-rated), executive function, MBI, family burden
Design
Open-label pre/post control or randomized control, 12 weeks
Publication angle
Separating apathy from depression is a recently prominent theme, with very little domestic research. Apathy is the largest hidden barrier to rehabilitation training, and resonates strongly with clinicians
S5Excessive daytime sleepiness and reduced alertness after stroke2 weeks–6 months post-stroke, ESS ≥10 or frequent sleepiness/reduced alertness during rehabilitation training (more common with thalamic, brainstemArousal & neurorehabilitationNo. 5Level APriority
Population
2 weeks–6 months post-stroke, ESS ≥10 or frequent sleepiness/reduced alertness during rehabilitation training (more common with thalamic, brainstem, or frontal lesions). n=40–60
Primary endpoint
ESS Epworth Sleepiness Scale
Secondary endpoints
Alertness during rehabilitation sessions (KSS at multiple pre/post time points), effective training time, MoCA, AES apathy (for differentiation), PSQI (to rule out night-sleep deficit), MBI
Design
Randomized control, 12 weeks
Publication angle
Post-stroke sleepiness directly eats into effective rehabilitation training time, yet it has almost never been studied as a standalone endpoint. Together with S3 fatigue and S4 apathy, it forms a "hypoarousal triad" — the three directions can run in parallel within the same department and share an assessment framework

Positioning of this domain: This is the domain with the least competition, the fastest recruitment, and the lowest ethical risk. The core angle is "people who do not want, or are not suited for, menopausal hormone therapy (MHT)" — a population that gynecology clinics face daily without a solution to offer.

Secondary endpoints
FMA motor function, MBI, length of stay, discharge mRS
Design
Randomized control, covering the full inpatient rehabilitation period (typically 4–12 weeks)
Publication angle
Closely matches real-world clinical practice, with the lowest enrollment and follow-up cost. Symptom-cluster analysis is a current methodological trend in rehabilitation research

Primary endpoint
WAB Western Aphasia Battery, Aphasia Quotient (AQ)
Secondary endpoints
CADL communication ability, mood, family communication burden
Design
Randomized control, 12 weeks
Publication angle
Because aphasia rehabilitation assessment is time-consuming, we recommend limiting this direction to sites with dedicated speech-language pathologists

Primary endpoint
MNA nutrition assessment + grip strength/skeletal muscle index
Secondary endpoints
Albumin/prealbumin, MBI, infectious complications, length of stay
Design
Randomized control, 12 weeks
Publication angle
The interdisciplinary nutrition-rehabilitation angle is publishable in clinical-nutrition journals. This draws a different author group than rehabilitation medicine and can run in parallel

Post-TBI syndrome has long lacked intervention options, and can be led by either neurosurgery or rehabilitation medicine
C

Menopause

Perimenopausal syndrome · 11 directions

This is the domain with the least competition, the fastest recruitment, and the lowest ethical risk. The core angle is "people who do not want, or are not suited for, menopausal hormone therapy (MHT)" — a population that gynecology clinics face daily without a solution to offer.

Primary endpoint
Modified Kupperman / MRS
Secondary endpoints
Hot flash diary, sleep, mood, quality of life, satisfaction with and intent to continue the intervention
Design
Randomized control or single-arm pre/post control, 12 weeks
Publication angle
The most clearly defined clinical gap population — guidelines explicitly note that no effective alternative exists for these patients, so the "clinical need" section of the paper practically writes itself
C3Add-on therapy for residual symptoms while on MHTWomen on standard MHT for 3+ months who still have residual symptoms (especially mood, sleep, cognition). n=40–60Adult mood & behavioral healthNo. 4Level A
Population
Women on standard MHT for 3+ months who still have residual symptoms (especially mood, sleep, cognition). n=40–60

Secondary endpoints
Sleep, mood, cognition, change in MHT dose, MHT adherence
Design
Open-label pre/post control, 12 weeks
Publication angle
MHT is highly effective for vasomotor symptoms, but its effect on mood and cognition is limited — this "efficacy gap" is precisely the rationale for add-on therapy

Secondary endpoints
Kupperman mood-related items, sleep, irritability, self-rated impact on family and work
Design
Randomized control, 12 weeks
Publication angle
Whether to use antidepressants for perimenopausal depression is a clinical point of debate, and there is clear room for non-pharmacological intervention in this borderline population
C5Perimenopausal sleep disorderPerimenopausal women, PSQI >7 or ISI ≥15. n=40–60Adult mood & behavioral healthNo. 4Level A
Population
Perimenopausal women, PSQI >7 or ISI ≥15. n=40–60

Publication angle
Correlation analysis linking nighttime hot flashes and sleep disruption is an interesting angle — distinguishing "sleep improvement driven by hot-flash improvement" from "independent sleep improvement"

Secondary endpoints
Kupperman/MRS, PSQI (distinguishing "tiredness from poor sleep" from "independent fatigue"), HADS, MENQOL, work productivity (WPAI)
Design
Randomized control, 12 weeks
Publication angle
Fatigue is consistently among the top 3 chief complaints in perimenopause, yet it is rarely studied as a primary endpoint — in Kupperman it is just a single item. Making it a standalone primary endpoint gives the study an immediately recognizable identity. The requirement to exclude anemia/hypothyroidism also demonstrates methodological rigor

Open-label pre/post control or randomized control, 12 weeks
Publication angle
In clinics, such complaints are often lumped together as "menopausal depression" and treated with antidepressants, but most do not actually meet the diagnostic criteria for depression. Separating "apathy" from "depression" is both an academic contribution and a direct answer to the physician's everyday dilemma of whether to prescribe

⚠️ Uniform compliance standard: In all oncology-direction protocols and papers, endpoints related to anti-tumor effect — such as tumor shrinkage rate, progression-free survival, or overall survival — must not be touched, and no claim of any kind regarding anti-tumor effect may be made. Endpoints must be strictly limited to symptom burden and quality of life. For safety, interactions with anti-tumor treatment must be recorded.

Secondary endpoints
Kupperman, mood, sleep, work productivity (WPAI)
Design
Randomized control, 12–24 weeks
Publication angle
"Menopausal brain fog" has been an international talking point in recent years, yet it is almost entirely unstudied domestically, giving it very high novelty. The estrogen-cognition hypothesis also provides theoretical grounding that makes the discussion section easier to write

Oncology Supportive Care

The full course of solid tumor treatment · 14 directions

The core positioning is supportive care, with no engagement whatsoever with anti-tumor effect. Main thrusts: cancer-related fatigue, chemotherapy-related cognitive impairment, and treatment-related insomnia and emotional distress — what these share is that guidelines acknowledge they exist, acknowledge no effective medication is available, and recommend non-pharmacological approaches.

Secondary endpoints
HADS, ISI, FACIT-F fatigue, quality of life EORTC QLQ-C30, return-to-work rate
Design
Randomized control, covering the chemotherapy period + 3 months of post-chemotherapy follow-up
Publication angle
CRCI is a front-line hot topic in international oncology supportive care, yet domestic data are extremely scarce. The subjective-objective cognition divergence analysis is a reliable bonus point in the discussion

Secondary endpoints
ECOG performance status, 6-minute walk, sleep, mood, chemotherapy completion rate and dose intensity
Design
Randomized control, 8–12 weeks
Publication angle
CRF has the highest prevalence (60–90%) of any symptom with no approved medication, and NCCN guidelines explicitly recommend non-pharmacological intervention — the single direction most aligned with Chienomoto's positioning. Setting "chemotherapy dose-intensity maintenance rate" as a secondary endpoint substantially raises clinical significance
O3Radiation-related fatigueSolid tumor patients receiving curative-intent radiotherapy (breast, head and neck, or prostate cancer preferred), enrolled before radiotherapy begiCognition, attention & fatigueNo. 3Level APriority
Population
Solid tumor patients receiving curative-intent radiotherapy (breast, head and neck, or prostate cancer preferred), enrolled before radiotherapy begins. n=50–80
Primary endpoint
FACIT-F or BFI fatigue trajectory during radiotherapy and through 4 weeks after completion
Secondary endpoints
Timing and peak of fatigue onset, number of radiotherapy interruptions/delays, ECOG, sleep, mood, QLQ-C30
Design
Randomized control, the full radiotherapy course (typically 5–7 weeks) + 4 weeks of post-radiotherapy follow-up
Publication angle
The time course of radiation-related fatigue is highly predictable (typically onset in weeks 2–3, peaking at the end of the course). This means the enrollment point, observation window, and assessment time points are all naturally fixed, making this one of the cleanest designs with the lowest attrition among all fatigue studies. Since patients attend daily for radiotherapy, follow-up cost is near zero
O4Apathy, reduced motivation, and excessive daytime sleepiness in cancer patientsSolid tumor patients during or after treatment, AES ≥34 or ESS ≥10, reporting "I don't feel like doing anything, I'm sleepy all day," with the HADArousal & neurorehabilitationNo. 5Level A

Secondary endpoints
FACIT-F fatigue (for differentiation from fatigue), HADS (covariate adjustment), engagement in daily activities, QLQ-C30, family observational rating
Design
Open-label pre/post control, 12 weeks
Publication angle
Oncology supportive care almost exclusively discusses fatigue, while "apathy" remains largely untouched as an independent construct. Yet in practice, patients who are "bedbound with no will to do anything" are very common, and are often misidentified and treated as depression. A three-way separation analysis of fatigue-apathy-depression carries high novelty

Publication angle
Insomnia prevalence in cancer patients is 2–3 times that of the general population, and long-term benzodiazepine use risk is also elevated. The sleep-medication-tapering angle applies here as well

Secondary endpoints
Hot flash diary, HADS, ISI, FACT-Cog, joint pain VAS, endocrine therapy adherence and discontinuation rate
Design
Randomized control, 12–24 weeks
Publication angle
"Adherence" is the trump-card endpoint for this direction — 30–50% of patients discontinue endocrine therapy within 5 years, and these symptoms are a leading cause. Linking symptom improvement to sustained adherence connects clinical significance directly to survival benefit
⚠️ Required pre-check
Because this direction involves a hormone-sensitive tumor, we must provide phytoestrogen/estrogen-like activity assessment data for the ingredients before enrollment begins, and this must be clearly explained in the protocol and informed consent. If the documentation is insufficient, this direction should be put on hold.

Design
Randomized control or pre/post control, 24 weeks
Publication angle
Radiation-induced cognitive impairment is a clearly defined clinical challenge (memantine is currently the only medication with evidence), leaving substantial room. Can be co-led by neurosurgery and radiation oncology

Secondary endpoints
CTCAE neurotoxicity grade, chemotherapy dose adjustment/interruption rate, pain VAS, quality of life
Design
Randomized control, covering the chemotherapy period
Publication angle
CIPN has no effective preventive measure and a clear need exists, but endpoint variability is large and the risk of a negative result is relatively high, so we recommend running this as an exploratory direction

Supportive-care research in the immunotherapy population is just beginning, giving it high novelty
⚠️ Notes
Immune-related adverse events must be clearly recorded, and the protocol must not include any language regarding immune modulation

Design
Prospective cohort + randomized control, 24 weeks
Publication angle
Survivors have the best adherence and the lowest attrition (they are the most motivated), making them the cancer-patient population easiest to follow through to completion. "Survivorship care" is a policy-level keyword of current interest

Design
Open-label pre/post control, 8 weeks
Publication angle
Palliative care research is limited
⚠️ Notes
Advanced-stage patients require particular ethical care, and informed consent and withdrawal procedures must be handled with far greater caution. We recommend limiting this direction to sites with an established palliative care team

Clinical Nutrition

Clinical nutrition · including tube-fed patients · 10 directions

Clinical nutrition is the department where compliance positioning feels most natural on this entire list — Chienomoto is a food to begin with, and food and nutritional supplements are exactly what clinical nutrition handles day to day, so there is none of the awkwardness of "treating a food like a drug." In addition, the assessment toolkit — NRS-2002, PG-SGA, MNA, grip strength, body composition — is already part of the department's routine work, keeping the marginal cost of data collection close to zero. The fact that No. 5 can be administered via nasal tube is especially important — it makes long-term tube-fed patients a research setting unique to clinical nutrition, a route most functional foods cannot enter.

Population
Inpatients on a standard polymeric or oligopeptide enteral formula (oral or tube feeding), stable condition. n=30–50

Secondary endpoints
Target caloric intake achievement rate, nutrition markers (prealbumin, weight), nursing workload time, flavor/acceptability score for oral intake
Design
Open-label pre/post control or crossover design, 8 weeks
Publication angle
Guidance on combining special-purpose foods with nutritional supplements is a current topic of both policy and clinical interest. This direction has the lowest barrier and the shortest duration, making it well suited as the first joint project with clinical nutrition, and the tolerability data it produces also underpins other directions in the department

Recommended as an entry-level project for clinical nutrition: it can be completed in 8 weeks, yields a publication with almost no added workload for the department, and also validates feasibility for follow-on directions.

N2Tolerability and level of consciousness in long-term tube-fed patientsPatients requiring long-term nasogastric, nasojejunal, or gastrostomy feeding due to stroke, TBI, hypoxic encephalopathy, etc., stable for 2+ weeks.Arousal & neurorehabilitationNo. 5Level APriority

Primary endpoint
Composite feeding tolerability score (gastric residual volume, bloating, diarrhea, vomiting) + CRS-R Coma Recovery Scale-Revised or GCS
Secondary endpoints
Prealbumin, weight, mid-upper arm circumference, pneumonia incidence, engagement in rehabilitation training, caregiver assistance burden
Safety endpoints (important)
Aspiration events, tube blockage, GI adverse events — must be recorded individually
Design
Open-label pre/post control or randomized control, 12 weeks
Publication angle
Nasal-tube administration is a strength unique to Chienomoto for this population — most functional foods cannot enter the enteral-feeding route. Tube-fed patients are concentrated in neurology, post-ICU, and rehabilitation wards, so follow-up attrition is zero. In addition, "tube passability and tolerability" can itself become an independently publishable paper

Required pre-check: We must first provide data on the product's solubility, viscosity, and tube passability (including blockage risk across various tube diameters); without this, the direction cannot be designed. This carries the strictest prerequisites of any direction on the full list.

N3Adjunct intervention for nutrition-risk-related fatigue and reduced appetite in inpatientsInpatients age 18+, NRS-2002 ≥3 (nutritional risk), FSS ≥4 or reporting overt fatigue, on a standard nutrition-support protocol. n=50–80Cognition, attention & fatigueNo. 3Level APriority

Secondary endpoints
PG-SGA subjective global assessment, grip strength, albumin and prealbumin, daily oral intake, appetite score (SNAQ), length of stay
Design
Randomized control (standard nutrition support ± Chienomoto), 8–12 weeks
Publication angle
Nutritional risk and fatigue are mutually causal, yet "fatigue" is rarely made the primary endpoint of nutrition-intervention research. The assessment framework in clinical nutrition is already well established, and every measure here comes from data the department already collects in routine practice
N4Nutritional support for sarcopenia and frailty in older adultsAge 65+, meeting AWGS 2019 sarcopenia diagnostic criteria, or FRAIL scale 1–3 (pre-frail to frail). n=50–80Cognition, attention & fatigueNo. 3Level B
Population

Secondary endpoints
Skeletal muscle mass index (bioelectrical impedance), FSS fatigue, MNA-SF, falls and hospitalization events, cognition and mood
Design
Randomized control (control arm receives resistance exercise + nutrition counseling), 24 weeks
Publication angle
Sarcopenia and frailty are currently among the most closely watched areas in geriatric medicine, and fatigue is precisely one of the five core criteria in the Fried frailty phenotype. Clinical nutrition, geriatrics, and rehabilitation medicine can all lead this, and it is submittable to both clinical-nutrition and geriatric-medicine journals

This is a different angle on the same population as A11 in the geriatric dementia domain — clinical nutrition and geriatrics can each lead their own study while sharing the same subject pool.

Primary endpoint
Postoperative delirium incidence (CAM or 3D-CAM, assessed daily on postoperative days 1–7)
Secondary endpoints
Postoperative cognition (MoCA at discharge and 3 months post-op), grip strength, length of stay, complication rate, 30-day readmission rate
Design
Randomized control, from 7 days preoperatively through 30 days postoperatively
Publication angle
Postoperative delirium after hip fracture occurs in 20–40% of older patients, and preventive options are limited. It is a hard outcome of shared interest to anesthesiology, geriatrics, and orthopedics alike. Nutritional intervention for delirium prevention is a current international hot topic, and delirium symptoms (fluctuating consciousness, agitation, hallucinations) align well with the No. 4 indication range

This direction's endpoint is a hard outcome with substantial clinical significance, but it requires daily postoperative assessment; we recommend limiting it to sites with an established elderly hip-fracture clinical pathway or ERAS team.

Publication angle
The "nutrition-cognition axis" is an interdisciplinary hot topic spanning geriatric medicine and clinical nutrition. Malnutrition is both a consequence and a risk factor of dementia, yet intervention research addressing this bidirectional relationship is very limited in Japan

Secondary endpoints
Pneumonia incidence, NIHSS, MBI activities of daily living, time to tube removal, length of stay
Design
Randomized control, 12 weeks
Publication angle
Dysphagia is a leading cause of malnutrition and aspiration pneumonia after stroke, making collaboration between clinical nutrition and rehabilitation medicine a natural fit. Since the product can also be given via tube, patients with restricted oral intake can be covered throughout the study, avoiding attrition from a change in administration route

Design
Randomized control (standard nutrition support ± Chienomoto), 12 weeks
Publication angle
Malnutrition and cancer-related fatigue are the two main pillars of oncology supportive care, but they are usually studied separately. Combining both into a single endpoint framework enables a joint publication between clinical nutrition and oncology

This addresses the same clinical issue as O2 in oncology, led by a different department. To avoid duplicating the same topic within one institution, we recommend choosing one or the other.

Secondary endpoints
CEBQ Children's Eating Behaviour Questionnaire, daily energy and protein intake, blood zinc and ferritin, sleep, mood, parental feeding-related stress
Design
Randomized control (control arm receives feeding-behavior counseling), 24 weeks
Publication angle
Picky/selective eating is among the most common complaints in developmental and pediatric-nutrition clinics, parental anxiety runs very high, and follow-up adherence is very good. Both developmental clinics and clinical nutrition can lead this, and it is the fastest-enrolling direction in this domain

Safety endpoints (important)
Blood potassium, blood phosphate, changes in creatinine and BUN, dialysis adequacy (Kt/V) — must be monitored before and after every dialysis session
Design
Open-label pre/post control, 12 weeks
Publication angle
Dialysis-related fatigue occurs in over 60% of patients and is the symptom patients care about most yet receive the least intervention for. A joint effort between nephrology and clinical nutrition benefits from a fixed population and a naturally recurring follow-up rhythm (dialysis 3 times weekly), giving extremely low attrition

Required pre-check: In populations with renal impairment, electrolyte and metabolic load must be strictly monitored for any supplementary food product. This direction cannot be designed until testing data for the product's potassium, phosphorus, and sodium content is obtained first; if the documentation is insufficient, it should be put on hold.
