Phase 1 Study of TVB-3567 for Acne

This study is testing a new oral capsule called TVB-3567 to see how safe it is, how well your body tolerates it, and how it moves through your body (pharmacokinetics or PK). Researchers are also looking at its effects on the body (pharmacodynamics or PD). Some parts of the study will include healthy volunteers, and other parts will include healthy volunteers with moderate to severe acne. The study aims to see if TVB-3567 is safe and well-tolerated. You may be able to join if you are a healthy adult between 18 and 55 years old.

Study design
This is a 4-part study with 128 planned participants. It is randomized, meaning you might receive TVB-3567 or a placebo (an inactive capsule), and some parts are double-blind, meaning neither you nor the study team will know which you receive.
What's involved
You would take an oral capsule. For some parts, researchers will measure how the drug is absorbed in your body over about 4 days. They will also track any side effects for about 7 to 8 days after you take the medicine.
Compensation
Not stated in the trial record.
Follow-up
Your safety will be monitored for 7 to 8 days after you take the study medicine. Drug levels in your body will be measured for up to 4 days.
