A Human Tick Kill Study to Investigate the Safety, Tolerability, and Whole Blood Concentration of TP-05

Healthy Volunteer Clinical Trial

Official title:
A Phase 2a, Randomized, Double-Blind, Placebo Controlled, Single-Center, Human Tick Kill Proof-of-Concept Study Evaluating the Safety, Tolerability, and Whole Blood Concentration of TP-05 (Lotilaner) in Healthy Volunteers

Clinical Trial Summary

This is a Phase 2a, randomized, double-blind, proof-of-concept, single-center study evaluating the safety, tolerability, and whole blood concentration of TP-05 (lotilaner) in the killing of ticks after they have attached to human skin.

Clinical Trial Description

The study will consist of a screening period of no more than 30 days. Participants will come to the study center on Day -1 for tick placements on the skin. Nymphal ticks that have been tested negative for human pathogens and are known to be ready to attach will be placed. On Day 1, the number of attached, live ticks will be counted. Participants will be randomized on Day 1 to receive either low dose or high dose of TP-05 or placebo. Tick attachment and mortality will be completed on Day 1 and after participants' return to the study center on Day 2 (24 hours after dosing). Participants will have ticks removed from the skin at the study center after the Day 2 (24 hours) tick count. Participants will come to the study center on Day 30 for another placement of ticks on the skin. Tick attachment and mortality will be determined on Day 30 and on Day 31 (24 hours after placement). Participants will complete the treatment period at Day 60. Participants will undergo a long-term safety follow-up period which will include additional safety and PK visits through Day 301. ;
