About this trial
This research program includes two coordinated prospective studies (FLOURISH and THRIVE) evaluating the real-world effectiveness of Noom's digital health programs on weight, cardiometabolic biomarkers, physiological health indicators, and program engagement.
FLOURISH is a 6-arm prospective cohort study comparing an Education-only control, Noom Weight, standard-dose compounded semaglutide, microdose compounded semaglutide, standard-dose tirzepatide (Noom Plus), and microdose tirzepatide (Noom Plus Microdose).
THRIVE is a nested 2-arm prospective study comparing a Proactive Health program to a Noom Free Tier control.
Participants complete monthly surveys, remote biomarker collection (Tasso device), connected-scale weigh-ins, and in-app biometric assessments (FaceScan, BodyScan). Microdose and Free Tier arms also use wearable fitness trackers. Primary outcomes are changes in cardiometabolic biomarkers, weight, body composition, and GLP-1 side effect profile. Total N = 2,310; 24-month duration.

Treatments tested in this trial
Noom Weight
BehavioralApp-based behavioral weight management program providing structured educational content, coaching, and self-monitoring tools focused on nutrition, physical activity, and habit formation.
Free Tier
BehavioralBasic free-to-use tier of the Noom app with limited features; no structured behavioral program or medication.
Education-only control
BehavioralWeekly informational newsletters based on the CDC curriculum for 12 months; no structured behavioral program or medication.
Semaglutide
DrugStandard clinical dosing of compounded semaglutide as part of Noom Med GLP-1Rx program per clinical standard of care, combined with behavioral coaching via the Noom app.
Tirzepatide
DrugStandard clinical dosing of tirzepatide as part of Noom Plus program per clinical standard of care, combined with enhanced behavioral coaching.
Microdose semaglutide
DrugBelow-standard clinical dosing (microdose) of compounded semaglutide as part of Noom Med GLP-1Rx Microdose program, combined with behavioral coaching via the Noom app.
Microdose tirzepatide
DrugBelow-standard clinical dosing (microdose) of tirzepatide as part of Noom Plus Microdose program, combined with enhanced behavioral coaching.

Trial outcomes
Primary outcomes
Change in Body Weight
Change from baseline in body weight (kg/lbs) measured via connected scale.
Change in fasting glucose
Change from baseline in fasting glucose (milligrams per deciliter (mg/dL)) measured via Tasso+ capillary blood collection device.
Change in HbA1c
Change from baseline in HbA1c (mmol/mol and percentage) measured via Tasso+ capillary blood collection device.
Change in LDL cholesterol
Change from baseline in LDL cholesterol (milligrams per deciliter (mg/dL)) measured via Tasso+ capillary blood collection device.
Secondary outcomes
Change in heart rate variability (HRV)
Change in heart rate variability (HRV) from baseline measured via in-app FaceScan feature (all arms) and wearables (select arms).
Change in resting heart rate (RHR)
Change in resting heart rate (RHR) from baseline measured via wearables (select arms).
Change in Peripheral Capillary Oxygen Saturation (SpO2)
Change in Peripheral Capillary Oxygen Saturation (SpO2) from baseline measured via wearables (select arms).
Change in sleep duration
Change in sleep duration (hours and minutes) from baseline measured via wearables (select arms).
Other outcomes
Depression symptoms
Change from baseline in Patient Health Questionnaire-8 (PHQ-8) score. Minimum score = 0; maximum score = 24. Lower score indicate none/mild depression; higher scores indicate severe depression.
Anxiety symptoms
Change from baseline in Generalized Anxiety Disorder-7 (GAD-7) score. Minimum score = 0; maximum score = 21. Lower scores = minimal or no anxiety; higher scores = severe anxiety.
Sleep disturbance
Change from baseline on Patient-Reported Outcomes Measurement Information System (PROMIS) Sleep Disturbance 8-item scale. Minimum score = 8; maximum score = 40. Lower scores = minimal or no sleep disturbance; higher scores = severe sleep disturbance.
Energy and Vitality
Change from baseline on Subjective Vitality Scale. Minimum score = 6; maximum score = 42. Lower scores = worse outcome (lower energy and vitality); higher scores = better outcome (more energy and vitality)
