Clinical Trial Summary

This is a double-blind, randomized, placebo-controlled, multiple ascending dose escalation study of TT-00920 in healthy subjects.

Description:

This is a double-blind, randomized, placebo-controlled, multiple ascending dose escalation study of TT-00920 in healthy subjects. Each dosing cohort will be comprised of 10 randomized subjects dosed three times daily for 13 days and one time for 1 day. The study will consist of a Screening Period, an In-house Period and a Follow-up.
