Summary
Brief summary
The phase 1 portion of the study is designed to evaluate the safety, tolerability,
pharmacokinetics (PK), and pharmacodynamics (PD) of TLC-6740 after single- and
multiple-ascending doses in healthy subjects. The phase 1b portion of the study is designed
to assess the safety, tolerability, and PK of TLC-6740 in subjects with obesity.
