Is this trial a fit for you?

Likely a good fit

Adults aged 18-65 with obesity (BMI ≥30) or overweight (BMI ≥27 to <30) who provide informed consent and meet nonpregnant, nonbreastfeeding criteria.

Probably not a fit

Individuals who do not respond to ASC36 or who experience adverse effects may not benefit from participating in the trial.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a randomized, double-blind, placebo-controlled study that uses single and multiple ascending doses to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and potential food effects of ASC36 tablets taken by adults with obesity or overweight. The trial will compare ASC36 tablets to placebo, with careful monitoring for adverse events and dose-related effects. The study aims to characterize how the drug behaves in the body and how meals may influence its absorption. It is conducted at a single Ascletis clinical site in South Miami, Florida, led by Ascletis Pharma with no listed collaborators.

Why it matters

Potential benefit: If successful, participants may experience improved weight management markers or tolerability data that could support future development of ASC36.

How similar studies have gone: Previous studies with similar therapeutic approaches have shown safety and pharmacokinetic data in early-phase trials, but this exact ASC36 approach is novel in this setting.
