Clinical Trial Summary

Phase 1b/2a, double-blind, randomized, placebo-controlled, single and multiple ascending dose study to evaluate the safety, tolerability and phage recovery profile of AP-PA02 multi-bacteriophage therapeutic candidate administered by inhalation in subjects with cystic fibrosis and chronic pulmonary Pseudomonas aeruginosa (PA) infection.

Description:

The study consists of two parts. Subjects with Cystic Fibrosis and chronic pulmonary Pseudomonas aeruginosa (PA) infection will be enrolled in either Part 1 (single-ascending dose cohorts) or Part 2 (multiple-ascending dose cohorts). Part 1 will evaluate single doses of AP-PA02 at two ascending dose levels, administered by inhalation. Treatment assignment will be randomized, double-blind, placebo-controlled in each of two ascending dose cohorts. Part 2 will also be double-blinded, randomized, placebo controlled, and will evaluate the safety and efficacy of multiple doses of AP-PA02 in each of two ascending dose level cohorts. Subjects in both Parts 1 and 2 will be followed for approximately 4 weeks and evaluated for safety, tolerability, phage titer profile and immunogenicity.
