Plain-language summary

The goal of this clinical trial is to learn if BIO101 treatment can improve the muscle strength of participants males and females, aged 18 to 84 years old, suffering from obesity (BMI≥30) or overweight (BMI ≥ 27) with one or more sequelae (e.g., hypertension, dyslipidemia, obstructive sleep apnea or cardiovascular disease, but excluding diabetes), and treated with semaglutide, a GLP1 agonist for 21 weeks. The main questions it aims to answer are: * Is BIO101 administered orally improving muscle strength, as measured with knee extension strength (using isokinetic dynamometry)? * Is BIO101 administration leading to additional medical problems for patients suffering from obesity or overweight with sequelae and treated with semaglutide? After the end of the study (after last patient did the last visit at the clinic), researchers will compare the BIO101-treated arm to the placebo control arm to see if the candidate drug has an effect on muscle strength, physical function, lean body mass and health related quality of life compared to placebo. BIO101 is the candidate drug and placebo is a look-alike substance that does not contain any active drug Participants will be asked to: * Take 2 pills every morning and every evening of BIO101 or placebo orally for 21 weeks. * Simultaneously, take semaglutide for 21 weeks while being on caloric restriction, following the doctor recommendation and approved prescribing information for semaglutide, with dose increasing up to at least a dose level of 1.7 mg and a maximum dose level of 2.4 mg. * Come to investigational site at screening, baseline, week 6, 13, 21 and week 33 (12 weeks after the end of treatment) for checkups and tests. * Answer to phone calls at week 25 and 29 as well (4 and 8 weeks after the end of treatment) on global health status and quality of life.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
