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.

Condition or disease Intervention/treatment Phase
Cystic Fibrosis Pseudomonas Aeruginosa Pseudomonas Lung Infection Lung Infection Pseudomonal Biological: AP-PA02 Other: Placebo Phase 1 Phase 2

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 three ascending dose levels, administered by inhalation. Treatment assignment will be randomized, double-blind, placebo-controlled in each of three 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 three 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.

Biological: AP-PA02
Bacteriophage administered via inhalation

Placebo Comparator: Placebo
Inactive isotonic solution
Other: Placebo
Inactive Placebo administered via inhalation

Primary Outcome Measures :
  1. Incidence of Treatment Emergent Adverse Events (Safety and Tolerability) of single and multiple doses of AP-PA02 administered by inhalation [ Time Frame: Day 1 pre-dose through End of Study Visit (Day 29 for SAD, Day 31 for MAD) ]
