Number of Participants With Anti-ETI-204 Antibodies
Serum anti-ETI-204 antibody titers were determined for all subjects in the Safety Population. Blood samples were collected and serum samples were assayed at an initial dilution of 1:10. Samples that were positive at the 1:10 dilution were serially diluted 1:2 and assayed until a negative result was attained. The titer of the most dilute sample yielding a positive result was recorded as the titer for that time point. Immunogenicity was measured by the number of participants in each study arm with anti-ETI-204 antibody values post-treatment ≥ 4-times higher than baseline at Day 8, 43 or 71, or if the titer was negative at baseline, the post-treatment sample(s) required a titer of at least 1:20 for it to be considered positive.

Brief Summary
Evaluate the safety, tolerability and pharmacokinetics (PK) of intravenous (IV) ETI-204 alone and in the presence of IV and oral ciprofloxacin
Detailed Description
An open-label, randomized, parallel group study of IV ETI-204 administered alone and in the presence of IV and oral ciprofloxacin in 40 adult volunteers. Subjects will be randomized to two groups of 20 subjects each in a 1:1 ratio. Group 1 will receive a single IV dose of ETI-204 16 mg/kg followed immediately at the end of the infusion by a single dose of IV ciprofloxacin (400 mg), followed by oral ciprofloxacin (750 mg) every 12 hours on Days 2-8 with the final oral dose on the morning of Day 9. Group 2 will receive IV ETI-204 (16 mg/kg) only. The total duration of the study for each subject will be approximately 100 days divided as follows:Screening: Days -28 to -2; In-Unit Phases: Days -1, 1 and 2 [all subjects]; Days 8, 9 and 10 [Group 1 only]; Out-of-Unit Visits: Day 9 [Group 2 only]; Day 16 (+/- 3 days); Day 29 (+/- 3 days); Day 43 (+/- 3 days); Final Visit: Day 71 (+/- 3 days). Following completion of a Screening visit subjects will arrive at the clinical research unit (CRU) on Day -1 following at least a 10-hour fast. On Day 1, subjects who qualify for entry into the study will be randomized to receive either ETI-204 plus IV and oral ciprofloxacin (Group 1) or ETI-204 only (Group 2) in a 1:1 ratio according to the randomization treatment assignment. On Day 1, all subjects will receive 50 mg oral diphenhydramine approximately 30 minutes prior to ETI-204 infusion. Subjects in Group 1 will receive IV ETI-204 16 mg/kg infused over 90 minutes, immediately followed by IV ciprofloxacin 400 mg infused over 60 minutes. Subjects in Group 2 will receive IV ETI-204 16 mg/kg infused over 90 minutes. All subjects will be discharged from the CRU on Day 2. On Days 2 through 8, subjects in Group 1 will receive oral ciprofloxacin (750 mg every 12 hours); the final dose will be received on the morning of Day 9. Oral ciprofloxacin dosing begins 24 hours after the initiation of the ciprofloxacin infusion on Day 1. Subjects in Group 1 will return to the CRU on Day 8 and will be discharged from the unit following completion of PK sampling on Day 10. Subjects in Group 2 will return to the unit for an out-patient visit on Day 9 but will not be re-admitted to the CRU for an overnight stay. All subjects will return to the CRU for out-patient visits on Days 16, 29, 43, and 71.
