This is a 4-part study. Part A will be a randomized, double-blind, placebo-controlled investigation of single ascending doses (SAD) to assess the safety, tolerability, pharmacokinetics (PK), and pharmacodynamic (PD) biomarkers of TVB-3567 administered orally in healthy participants. Part B will be a randomized, open-label, 2-way crossover investigation to assess the effect of food on a single dose TVB-3567 administered orally in healthy participants. Parts C and D will be randomized, double-blind, placebo-controlled investigations of multiple ascending doses (MAD) to assess the safety, tolerability, PK, and PD/biomarkers of TVB-3567 administered orally in healthy participants without and with moderate to severe acne, respectively.
