MP101 in Adults With Acute Pseudomonas Aeruginosa Pneumonia

This clinical trial is a Phase 1 study with a randomized, double-blind, placebo-controlled, single-dose, sequential dose-escalation design and consists of two dose cohorts. After the safety of the low-dose cohort (Cohort A) is evaluated, dosing will proceed to the high-dose cohort (Cohort B). The investigational product, MP101, is a cocktail formulation comprising two bacteriophages. Participants in Cohort A will receive low dose, and participants in Cohort B will receive high dose. MP101 will be administered as a single intravenous infusion. The placebo is a clear solution with the same appearance as MP101 but without bacteriophages, and it will be administered in the same manner.

All study subjects will receive concomitant antibiotic therapy. The choice of the concomitant antibiotic will be based on the results of antibiotic susceptibility testing and will follow the best available therapy, as determined by the investigator.
