CREST: Samphire Guided Care Program on Wellbeing, Work Productivity, and Quality of Life (CREST)
A 12-Week Prospective Cohort Study Evaluating the Efficacy of the Samphire Guided Care Program on Wellbeing, Work Productivity, and Quality of Life in Individuals With Menstrual and Pelvic Health Conditions
This study evaluates the feasibility and efficacy of the Samphire Guided Care (SGC) program
- a 12-week structured digital health program combining clinician-led onboarding, at-home neuromodulation using the Lutea tDCS device, neuromodulation coach support, and app-based symptom tracking - on work productivity, employee wellbeing, and quality of life in individuals experiencing mood and cognitive symptoms associated with menstruation, perimenopause, or menopause.

Detaillierte Beschreibung
The CREST study is a prospective, observational, two-group cohort study conducted in a fully decentralized, at-home format. No randomization, blinding, or placebo comparator is employed.
All enrolled participants receive access to the full SGC program, which includes: a clinician-led eligibility assessment at onboarding conducted by a third-party women's health clinician; at-home transcranial direct current stimulation (tDCS) using the Lutea consumer wellness device (for eligible participants who opt in); ongoing support from a Samphire neuromodulation coach; and app-based symptom tracking via the Alethios digital research platform.
Participants are prospectively allocated to one of two groups based on neuromodulation eligibility, device uptake, and adherence: Group A (neuromodulation cohort, target n=35) comprises participants assessed as eligible who accept the device and complete at least 30% of recommended sessions across the 12-week program; Group B (comparison cohort, target n=15) comprises participants who either decline the device or complete fewer than 30% of sessions.
Group allocation is determined retrospectively at Week 12 based on automated device usage logs. Both groups complete identical assessment schedules.
Primary outcomes are work productivity (WPAI subscales) and employee wellbeing (EQ-5D-5L).
Secondary outcomes include PHQ-9, GAD-7, ISI, WPAI, PSST, and BrainHQ cognitive assessment.
Exploratory outcomes include pain NRS, PGIC, NPS, HCRU, optional wearable physiological data, and clinician-rated CGI-S and CGI-I.
All study activities are conducted remotely via the Alethios digital research platform and Samphire mobile application. Electronic informed consent is obtained prior to any study-related data collection.

Group A - Neuromodulation Cohort
Participants assessed as eligible for neuromodulation at the clinician onboarding consultation who accept the Lutea device and complete at least 30% of recommended tDCS sessions across the 12-week program.
Group A participants receive the full SGC program including clinician consultation, Lutea device, neuromodulation coach support, and app-based symptom tracking.
|
The Lutea device (Samphire Group, Inc.) is an FCC-registered consumer wellness wearable that delivers low-intensity transcranial direct current stimulation (tDCS) targeting the primary motor cortex (M1) and dorsolateral prefrontal cortex (DLPFC).
Sessions are 20 minutes in duration at a recommended frequency of multiple sessions per week, self- administered at home.
The device does not meet the FDA's statutory definition of a medical device; it is intended for general wellness purposes and is not cleared or approved for the diagnosis, cure, mitigation, treatment, or prevention of any disease.

Group B - Comparison Cohort
Participants who either decline the Lutea device following the clinician consultation, or who accept the device but complete fewer than 30% of recommended sessions across the 12-week program.
Group B participants receive the same SGC program components as Group A excluding substantive neuromodulation engagement.
