Virus cocktail targets superbug pneumonia in first human test
NCT ID NCT07492771
First seen Jun 26, 2026 · Last updated Jul 29, 2026 · Updated 3 times
Summary
This early-stage trial tests MP101, a mix of two viruses that attack bacteria (phages), in 18 adults with Pseudomonas aeruginosa pneumonia. Participants receive a single dose of MP101 or a placebo alongside standard antibiotics. The main goal is to check safety and how the body handles the treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- MP101 (a cocktail of two bacteriophages)
- What this could lead to
- If successful, this could point toward a new treatment option for hard-to-treat Pseudomonas pneumonia, especially when antibiotics fail.
- What could go wrong
- This is a very early, small phase 1 trial with only 18 participants. The main goal is safety, not effectiveness, and it may not work or have side effects.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Subjects aged 19 years or older. * Clinical diagnosis of acute pneumonia with radiologic evidence of pulmonary infiltrates. * Confirmed Pseudomonas aeruginosa (PA) infection via valid respiratory specimens. * PA isolate demonstrates susceptibility to MP101 and non-susceptibility to current antibiotic therapy. * Adequate organ function as defined by hematological, hepatic, and renal laboratory parameters . Exclusion Criteria: * Persistent septic shock or hemodynamically unstable condition. * Active pulmonary tuberculosis or non-bacterial pneumonia. * Significant pleural effusion or lung abscess requiring therapeutic drainage. * Clinically significant cardiovascular, hepatic, or renal impairment . * Immunocompromised status or hematological malignancies. * Known hypersensitivity to bacteriophages, study components, or concomitant antibiotics. * Participation in another clinical trial within 30 days prior to screening. * Any medical condition that, in the opinion of the investigator, would make the subject unsuitable for the study.
