Plain English summary of protocol

Background and study aims
Obesity can raise the risk of health problems such as type 2 diabetes, heart disease, heart failure, and fatty liver disease. BC-006 is a new type of medicine that works by entering liver cells and reducing the production of a protein called Activin E. This protein is involved in how the body stores fat. By lowering Activin E, BC-006 may help reduce body fat and improve lean muscle. The aim of this study is to see how safe BC-006 is, how the body processes it, how it affects the body, and which dose works best in adults with obesity.

Who can participate?
Adults aged 18 years to 70 years with a body mass index between 30 and 45 kilograms per square metre may be able to take part. Participants must have at least one obesity related condition, such as high blood pressure or high cholesterol, and their weight must have been stable in recent months. People cannot take part if they have certain medical conditions, diabetes, recent use of obesity treatments, or other findings that might make the study unsafe for them.

What does the study involve?
Participants will be placed into one of three groups at random. They will receive either BC-006 at different dose levels or a placebo. The study drug will be given as an injection under the skin on three occasions: Day 1, Day 30, and Day 115. Participants will then be followed for 170 days after their last dose. During the study, they will attend several visits for health checks, blood tests, heart monitoring, and scans that measure body fat and liver health.

What are the possible benefits and risks of participating?
The study may not provide direct benefit to those taking part. However, the information gained may help improve future treatments for obesity. Possible risks include side effects from the study drug, reactions at the injection site, and discomfort from study procedures such as blood tests. The study team will monitor participants closely to reduce these risks.

Where is the study run from?
The study is taking place at research centres in Australia located in Bayswater, Camberwell, and Sydney.

When is the study starting and how long is it expected to run for?
April 2026 to August 2027.

Health condition(s) or problem(s) studiedObesity
InterventionThis is a Phase IIa, randomized, double-blind, placebo-controlled trial designed to evaluate the safety, tolerability, PK, PD, and efficacy of BC-006 administered via subcutaneous injection (SC) in adults with obesity. The study randomisation will be carried out by Medidata Randomisation and Trial Supply Management (RTSM) to randomise participants. During randomisation procedures, only the randomisation number will be displayed in the randomisation notice. The unblinded pharmacist will check against the randomisation list to ensure participants will receive IP or placebo.

This is a multi-dose group design where three treatment groups (Groups A to C), each comprising at least 12 subjects with obesity, will be enrolled to receive a SC dose of BC-006 Injection or placebo on Days 1 (dose 1), 30 (dose 2), and 115 (dose 3). Subjects will be followed for a total of 170 days after receiving their last dose.
The planned dosing strategy includes the following groups: Group A: 200 mg BC-006 Injection, Group B: 300 mg BC-006 Injection, Group C: Placebo
