Frequently asked questions about BX004-A

What is BX004-A?

BX004-A is an investigational small molecule developed by BiomX Inc. for chronic Pseudomonas aeruginosa infection in people with cystic fibrosis. It is a nebulized therapy designed to target the bacterium P. aeruginosa. BX004-A has completed a Phase 1 clinical trial and has received Orphan Drug designation from the FDA.

What is BX004-A used for in chronic Pseudomonas aeruginosa infection?

BX004-A is being developed to treat chronic Pseudomonas aeruginosa pulmonary infection in patients with cystic fibrosis. It is administered as a nebulized therapy. The goal is to target and reduce P. aeruginosa bacteria in the lungs. It is investigational and has not been approved for commercial use.

What does BX004-A target?

BX004-A targets Pseudomonas aeruginosa, a Gram-negative bacterium that causes chronic lung infections. The drug is a small molecule designed to specifically act against this pathogen. By targeting the bacteria directly, it aims to reduce the bacterial burden in cystic fibrosis patients with chronic P. aeruginosa infection.

Who is developing BX004-A?

BX004-A is being developed by BiomX Inc., a biotechnology company publicly traded under the ticker PHGE. BiomX focuses on developing therapies for infectious diseases. The company is advancing BX004-A as a potential treatment for chronic Pseudomonas aeruginosa infection in cystic fibrosis patients.

What phase is BX004-A in?

BX004-A is in Phase 1 clinical development. It has completed one Phase 1 trial, and no active trials are currently listed. The FDA has granted Orphan Drug designation for BX004-A. It remains an investigational therapy and has not been approved by the FDA.

What clinical trials is BX004-A in?

BX004-A has been evaluated in a completed Phase 1 trial, NCT05010577, titled Nebulized Bacteriophage Therapy in Cystic Fibrosis Patients With Chronic Pseudomonas Aeruginosa Pulmonary Infection. The trial enrolled 43 participants across the United States, Czechia, Israel, Netherlands, and Spain. It was randomized, double-blind, and placebo-controlled.
