Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Semaglutide is approved for weight management (weight loss and weight maintenance) in adult obese patients. Drug treatments like semaglutide that result in weight-loss can also decrease muscle mass. The purpose of this study is to investigate the effect of ACM-001.1 (the study drug) on how much muscle is lost when a person takes it with semaglutide (PROACT 1) and how much muscle mass is gained when a person continues taking ACM-001.1 but stops taking semaglutide (PROACT 2).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study will compare the effects of ACM-001.1 (the study drug) when it is taken at the same time as semaglutide, and after semaglutide treatment has stopped. To allow the measurement of the effect of each treatment type, the study will involve the use of a placebo tablet and a 'sham' (fake) injection of semaglutide.

Various tests will be used to measure the effect of the study drug. These will include a DEXA scan (like an X-ray). The study will also include measurements of weight, tests on the heart, and tests of muscle function. Questionnaires relating to health and well-being will also be used. Blood samples will be taken and tested to check overall health.

The study takes place in two parts, each lasting 20 weeks. Between each 20-week period) there is a 4-week 'wash-out' period during which patients will not receive any treatment.

ACM-001.1 (or placebo) is a tablet for oral administration (by mouth). Two doses of ACM-001.1 are being tested in this study. The semaglutide or sham injection will be administered once every week.

The study is 'double-blind', neither the patient or the doctor will know if the patient is taking ACM-001.1 or placebo or which dose they receive.

The total study is expected to run for approximately 18 months.

Arm 1 semaglutide, low dose ACM-001.1 or sham injection/placebo during semaglutide therapy PROACT 1

Patients in Arm 1 will be randomized to a crossover design, to receive either semaglutide and low dose ACM-001.1 BID or a sham injection and placebo ACM-001.1 BID during Period 1. Following washout, in Period 2 patients within Arm 1 and Arm 2 will cross-over onto the opposing treatment.
