TT-00920 ...Study Participants
42This is a first-in-human, randomized, double-blind, placebo-controlled study. The primary objectives of the study were to investigate the safety and tolerability and determine the PK profiles of single ascending doses (SAD) of TT-00920 administered to healthy subjects. The secondary objectives of the study were to assess the effect of food on the PK of TT-00920 following an oral dose.
There will be 4 single-ascending-dose cohorts and 1 cohort for food effect assessment to assess the safety, tolerability, and PK profile. A pilot dose of 20 mg will be evaluated in 2 subjects (all receiving TT-00920) for safety, tolerability, and PK profile before the initiation of dose escalation.
In single-ascending-dose cohorts, 8 subjects per cohort will be enrolled and randomized to assess the safety, tolerability, and PK profile. In food effect cohort, there will be 8 subjects (all receiving TT-00920). Subjects in food effect cohort will receive 2 single dose periods (Fasted/ Fed) in an open-label, crossover design.
