Number of Participants Who Used Rescue Medication

Rescue treatment with a licensed antibiotic according to the local standard of care was provided to participants if, in the judgment of the investigator, there was no clinical improvement or worsening of their condition to an extent that it would be in the best interest of the participant treated with an alternate therapy for safety reasons.

Time frame: Baseline to Day 12

Population: mITT population included participants who received at least one dose of IP and had a positive bacterial culture (presence of one or more bacterial species at or above pathological threshold) at baseline in the study. Here, the number of participants analyzed refer to the participants evaluable for this outcome at specified time point.

Number of Participants With Bacterial Eradication

Bacterial eradication was defined as absence of all bacterial species present at or above pathological threshold at baseline in the study eye. Bacterial species were identified by Matrix Assisted Laser Desorption/Ionization-Time of Flight Mass Spectrometry, using their unique protein patterns. Pathological threshold for individual bacterial species was based on CFU/mL threshold levels established by Cagle and modified by Leibowitz for different ocular bacterial species found in the specimens collected from each participant.

Number of Participants With Bacterial Eradication Among Who Received SHP640 or Placebo on Day 5

Bacterial eradication was defined as absence of all bacterial species present at or above pathological threshold at baseline in the study eye. Bacterial species were identified by Matrix Assisted Laser Desorption/Ionization-Time of Flight Mass Spectrometry, using their unique protein patterns. Pathological threshold for individual bacterial species was based on colony-forming unit (CFU)/mL threshold levels established by Cagle and modified by Leibowitz for different ocular bacterial species found in the specimens collected from each participant. Data analysis was performed in SHP640 and placebo reporting groups only but not in PVP-I 0.6%.
