Brief 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.

Detailed 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.
