GV101 in Healthy Obese Participants

Completed · Phase 2 · Has a placebo group

Conditions studied: Weight Management

In brief

The purpose of this trial is to evaluate the efficacy and safety of GV101 for weight loss over a range of doses in participants with obesity. The primary efficacy endpoint is the mean percent change in body weight from baseline at Week 16 in each treated group as compared with placebo.

• Have a stable body weight (< 3 kg self-reported change during the previous 90 days) before screening.
• Willing to refrain from drastic changes in diet and physical activity regimen (those recommended via lifestyle counseling are acceptable).
• Participants of reproductive potential (any male who has not undergone vasectomy more than 6 months prior to the first dose of investigational medicinal product [IMP] and any female who has not undergone bilateral oophorectomy, hysterectomy, total abdominal hysterectomy with bilateral salpingo-oophorectomy, bilateral tubal occlusion or ligation or who is not postmenopausal (a. A woman ≥55 years old not on hormone therapy, with amenorrhea for ≥12 months without an alternative medical cause, or b. A woman at least 55 years of age with a diagnosis of menopause prior to starting hormone replacement therapy or c. A woman > 40 and < 55 years of age with an intact uterus, not on hormone therapy, who has cessation of menses for at least r1 year without an alternative cause, AND a follicle-stimulating hormone (FSH) >25 mIU/mL or d. A woman with premature ovarian failure confirmed by historical FSH levels in the postmenopausal range prior to initiating HRT, or by a documented irreversible medical condition causing permanent infertility.)), who are heterosexually active, must agree to use a combination of two of the following methods of contraception (males must ensure their partner(s) use at least one method below to ensure at least two contraceptive methods are in place and must continue with this contraceptive plan for 90 days after the last dose of IMP; females must continue with this contraceptive plan for 28 days)

• Evidence of clinically significant hepatic or renal impairment, including but not limited to screening test results of ALT and AST above 1.5x the ULN, total bilirubin above the ULN, history of Gilbert's syndrome or of elevated bilirubin, especially while fasting.
• History of clinically significant QTcF interval prolongation, or a QTcF interval of > 470 ms in females or of > 450 ms in males at screening.
• Clinically significant vital sign abnormalities at screening (systolic blood pressure [SBP] < 90 or > 150 mm Hg, diastolic blood pressure [DBP] < 50 or > 100 mm Hg, or heart rate [HR] < 50 or > 100 bpm). Retesting is allowed at the discretion of the site Investigator or designee.
• Not willing to limit alcohol consumption to 2 drinks per day for males and 1 drink per day for females. History of alcohol misuse within 1 year prior to screening or regular alcohol consumption (more than 14 units per week [1 unit = 150 mL wine, 360 mL beer, or 45 mL 40% alcohol]) within 6 months prior to the screening visit.
