Chronic Pseudomonas Aeruginosa InfectionPhase 2NCT06998043
Study With Phage for CF Subjects With Pseudomonas Lung Infection
A Phase 2 study testing BX004 in people with Chronic Pseudomonas Aeruginosa Infection and Cystic Fibrosis (CF), run by BiomX Ltd at 14 sites in United States.
Trial summary
The goal of this Phase 2b clinical trial is to see if nebulized phage (BX004) can treat chronic Pseudomonas aeruginosa (PsA) lung infection in CF subjects. The primary goal is to see if 8 weeks of twice daily BX004 can reduce the amount of PsA in the sputum compared to placebo (on top of background CF therapy). Read more about this study

About this study
Official title: A Phase 2b, Randomized, Double-Blind, Placebo-Controlled, Multicenter Study to Evaluate Nebulized Bacteriophage Treatment in Outpatient Adult Cystic Fibrosis (CF) Subjects With Chronic Pseudomonas Aeruginosa (PsA) Pulmonary Infection
The goal of this Phase 2b clinical trial is to see if nebulized phage (BX004) can treat chronic Pseudomonas aeruginosa (PsA) lung infection in CF subjects. The primary goal is to see if 8 weeks of twice daily BX004 can reduce the amount of PsA in the sputum compared to placebo (on top of background CF therapy).
Read the detailed description
This is a randomized, double-blind, placebo-controlled, multicenter study to evaluate BX004 in CF subjects with chronic PsA pulmonary infection. The main purpose of the study is to evaluate whether BX004 reduces the PsA burden in the sputum of CF subjects with chronic PsA pulmonary infection. Secondary endpoints are to see how well BX004 works in improving lung function and quality of life, reducing the amount of PsA in the sputum, getting negative sputum cultures for PsA, and safety and tolerability. Clinically stable CF subjects with a confirmed diagnosis of CF and chronic PsA pulmonary infection will be enrolled. Subjects will be included in a 6-month post-dose safety follow-up. A Data Safety Monitoring Board of the CF Foundation will monitor safety.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing BX004 in people with Chronic Pseudomonas Aeruginosa Infection and Cystic Fibrosis (CF), run by BiomX Ltd at 14 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 22 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 14 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Urania Rappo, MD (1-617-256-2625, uraniar@biomx.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in sputum Pseudomonas aeruginosa (PsA) burden at 8 weeks (EOT) (time frame: 8 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Jul 2025; AzTrials last refreshed its copy on 26 Oct 2026.
