Number of Participants That Experienced Grade 2 or Higher Treatment-emergent Adverse Events in the ITT Population
Tidsram: Day 1 through Day 30
|
An event that occurred during the treatment period was considered a treatment-emergent AE if it was not present before the first dose of investigational product or was present before the first dose of investigational product and increased in severity during the treatment period.

Day 1 through Day 30

Change From Baseline to Day 30 in log10 P. Aeruginosa Total Colony Counts in Quantitative Sputum Cultures After Administration of IV Bacteriophages/Placebo in Stage 2a and 2b
Tidsram: Day 1 Post-infusion, Day 2, Day 5, Day 8, and Day 30
|
Mean change from baseline in log10-transformed counts of P. aeruginosa colony forming units per milliliter (CFU/mL) is presented for each time point through Day 30 as well as for each participant's minimum and maximum change from baseline.
Undetectable colony counts are substituted with the limit of detection (LOD) of the assay (1 x 10^4 CFU/mL).

Desirability of Outcome Ranking (DOOR) Probability Calculated Using the Greatest Reduction by Day 8 Follow-up Visit in Stage 2a and 2b
Tidsram: Day 1 Post-infusion, Day 2, Day 5, and Day 8
|
A DOOR rank is calculated for each participant based on the following ranking from most (rank 1) to least (rank 4) desirable outcome using each participant's greatest reduction from baseline in log10 P. aeruginosa CFU/mL by Day 8: Rank 1=No SAE (related to study product) and > 2 log10 reduction in P. aeruginosa CFU/mL.
Rank 2=No SAE (related to study product) and 1-2 log10 reduction in P. aeruginosa CFU/mL.
Rank 3=No SAE (related to study product) and < 1 log10 reduction in P. aeruginosa CFU/mL.
Rank 4=SAE (related to study product).
The DOOR probability is estimated by: Pr[DOOR]= Pr[DOORIV > DOORP] + 1/2Pr[DOORIV = DOORP] where DOORIV and DOORP are the DOOR ranks for bacteriophage (phage) and placebo arms, Pr[DOORIV > DOORP] is the proportion of DOOR ranks from IV phage dose exceeding DOOR ranks from placebo, and Pr[DOORIV = DOORP] is the proportion of phage and placebo DOOR ranks being the same.
Undetectable colony counts are substituted with the LOD of the assay (1 x 10^4 CFU/mL)
