• To assess the efficacy of ROSE-010 on prospective consumption;
• To assess the efficacy of ROSE-010 on desire to eat;
• To assess the efficacy of ROSE-010 on palatability;
• To characterize the pharmacokinetics (PK) of ROSE-010 following subcutaneous (SC) administration on Day 1 and Day 7; and
• To evaluate safety and tolerability of SC administrations of ROSE-010 to overweight and obese subjects.

Study Overview

• Status: Completed
• Conditions: Obesity; Overweight
• Intervention / Treatment: Drug: Placebo; Drug: ROSE-010 99 mcg; Drug: ROSE-010 150 mcg

Detailed Description

This is a randomized, placebo-controlled, double-blind, parallel-group Phase 2 study evaluating the efficacy, safety, and PK of daily administrations of the GLP-1 analogue ROSE-010 on appetite and food intake in overweight and obese female subjects. The study is planned to include 3 parallel groups, as follows:

Group 1: 99 mcg ROSE-010 (15 subjects) administered SC once daily for 7 consecutive days.

Group 2: 150 mcg ROSE-010 (15 subjects) administered SC once daily for 7 consecutive days.

Group 3: Placebo (10 subjects) administered SC once daily for 7 consecutive days.

On Day 1, subjects will be randomized to receive ROSE-010 or placebo. Study drug will be administered SC once daily (30 minutes before lunch) for 7 consecutive days (Days 1 to 7). Assessments of hunger, satiety, prospective consumption, desire to eat, palatability, and nausea will be performed. Blood samples will be collected to evaluate PK.

5. History or presence of chronic pancreatitis or presence of acute pancreatitis within 6 months before Screening.
6. A history of Major Depressive Disorder within the last 2 years.
7. Any lifetime history of a suicide attempt.
8. Previous bariatric surgery, procedure for obesity, or GI surgery altering GI passage, motility, and/or nutrient absorption or recent (within 6 months of Screening) changes in body weight (greater or equal to 5%) due to dieting, including commercial weight loss programs, or pharmacologic treatment.
9. Currently on or planning to participate in any weight loss regimen during the course of the study.
10. Personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia type 2.
11. History of malignancy, except the following: curatively resected basal cell or squamous cell skin cancers, cervical cancer in situ, or resected colorectal polyps more than 5 years prior to Screening.
12. Abnormal fasting blood glucose (ie, greater than 125 mg/dL) at Screening or Check-In and/or HbA1c (greater than 6.4%) at Screening, or prior history/diagnosis of any type of diabetes mellitus (eg, type 1, type 2, or gestational).

13. Use of any prescribed or over-the-counter (OTC) medication other than approved contraceptives within 14 days or 5 half-lives (whichever is longer) prior to dosing on Day 1 and throughout the study.

    Note: Following study drug administration, medications used for the treatment of adverse events (AEs) may be allowed at the discretion of the Investigator or designee.

14. Any glucagon-like peptide-1 (GLP-1) receptor agonist, GLP-1/glucose-dependent insulinotropic polypeptide dual agonist (eg, tirzepatide), or any prescription or OTC medications intended for weight loss or with a potential impact on weight and appetite regulation (eg, stimulant medications) within 6 months of Screening.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Food Consumption	The amount of food (weight and energy content) consumed during lunch after administration of ROSE-010 at 2 dose levels compared to placebo.	30 minutes

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Hunger	Hunger across 6.5 hours of Area Under Evaluation (AUE) defined by time in hours (h) multiplied by the subject reported value on a visual analogue scale at each time point measured in mm on a 0 to 100 mm scale and where 0 is not hungry at all and 100 is maximum hunger. AUE is a sum of hunger across the time period and is calculated as h*mm. Simplistically, if the subject was not hungry at all across the period the AUE would be zero. The higher the AUE number, the higher the level of hunger throughout the observation period.	6.5 hours Day 7
Satiety	Satiety across 6.5 hours of Area Under Evaluation (AUE) defined by time in hours (h) multiplied by the subject reported value on a visual analogue scale at each time point measured in mm on a 0 to 100 mm scale and where 0 is not feeling full at at all and 100 is maximum feeling of fullness. AUE is a sum of satiety across the time period and is calculated as h*mm. Simplistically, if the subject was not full at all across the period the AUE would be zero. The higher the AUE number, the higher the level of satiety throughout the observation period.	6.5 hours Day 7
Prospective Consumption	Prospective consumption across 6.5 hours of Area Under Evaluation (AUE) defined by time in hours (h) multiplied by the subject reported value on a visual analogue scale at each time point measured in mm on a 0 to 100 mm scale and where 0 is indicates no anticipated need to eat and 100 is maximum anticipated need to eat. AUE is a sum of prospective consumption across the time period and is calculated as h*mm. Simplistically, if the subject has no anticipated need or desire to eat at all across the period the AUE would be zero. The higher the AUE number, the higher the level of prospective consumption throughout the observation period.	6.5 hours Day 7
Desire to Eat	Desire to eat across 6.5 hours of Area Under Evaluation (AUE) defined by time in hours (h) multiplied by the subject reported value on a visual analogue scale at each time point measured in mm on a 0 to 100 mm scale and where 0 is no desire to eat at all and 100 is maximum desire to eat. AUE is a sum of the desire to eat across the time period and is calculated as h*mm. Simplistically, if the subject had no desire to eat at all across the period the AUE would be zero. The higher the AUE number, the higher the desire to eat throughout the observation period.	6.5 hours Day 7
Palatability	Palatability (tastiness) score on a visual analogue scale (0 to 100 mm) where 0 is not palatable at all and 100 is the maximum palatibility. The higher the score, the more palatable the reported outcome.	30 minutes Day 7
Nausea	Nausea across 6.5 hours of Area Under Evaluation (AUE) defined by time in hours (h) multiplied by the subject reported value on a visual analogue scale at each time point measured in mm on a 0 to 100 mm scale and where 0 is not nauseous at all and 100 is maximum nausea. AUE is a sum of hunger across the time period and is calculated as h*mm. Simplistically, if the subject was not nauseous at all across the period, the AUE would be zero. The higher the AUE number, the higher the level of nausea throughout the observation period.	6.5 hours Day 7
Plasma PK Analysis of ROSE-010 Time to Max Concentration Tmax	Plasma PK analysis of ROSE-010: Time to max plasma concentration in minutes	Day 7
Plasma PK Analysis of ROSE-010 Cmax	Plasma PK analysis of ROSE-010, measurement of max plasma concentration.	Day 7
Half-life	Time of plasma elimination half-life calculated for both ROSE-010 doses	Day 7
