Detailed Description
This Phase 1 study is a randomized, double-blind, single- and multiple-ascending dose trial to evaluate the safety, tolerability, food-effect, and pharmacokinetics of TP-05 in healthy subjects. Subjects will be enrolled in 5 sequential, ascending single dose cohorts and 3 multiple, ascending dose cohorts. Dose escalation will be approved by a safety monitoring committee before beginning the next cohort. The Safety Review Committee (SRC) will evaluate if any dose-limiting adverse events (AEs) through Day 15 (in Cohorts 1-5) or through Day 36 (in Cohorts 6-8) occurred in a cohort before proceeding to dosing in the next dose level. In addition, the SRC will review selected PK parameters after selected cohorts. Skin punch biopsies, and venous, capillary, and urine samples may be collected at various timepoints for pharmacokinetic analysis. Safety assessments include monitoring of adverse events, clinical laboratory testing, vital sign measurements, physical examinations, and ECGs. A blood sample may also be collected to evaluate tick mortality upon exposure.
