Trial design
Randomised, active investigational arm: omn6 (intravenous powder for infusion) administered in dose-escalating cohorts — cohort 1: 150 mg/day; cohort 2: 300 mg/day; cohort 4: 450 mg/day; participants in each sub-cohort receive three omn6 infusions plus background antibiotic therapy. comparator arm: placebo (saline solution for infusion) — participants receive three placebo (saline) infusions plus background antibiotic therapy. background antibiotic therapy (bat) may include meropenem, ampicillin/sulbactam and/or colistin as adequate empiric treatment per local epidemiology.-controlled, adaptive Phase II trial across 13 sites in Greece, Hungary, Italy.
- Randomised
- Yes
- Comparator
- Active investigational arm: OMN6 (intravenous powder for infusion) administered in dose-escalating cohorts — Cohort 1: 150 mg/day; Cohort 2: 300 mg/day; Cohort 4: 450 mg/day; participants in each sub-cohort receive three OMN6 infusions plus background antibiotic therapy. Comparator arm: Placebo (SALINE solution for infusion) — participants receive three placebo (saline) infusions plus background antibiotic therapy. Background Antibiotic Therapy (BAT) may include Meropenem, Ampicillin/Sulbactam and/or Colistin as adequate empiric treatment per local epidemiology.
- Adaptive
- True, sequential dose-escalation design with up to 3 dose cohorts and up to 2 sub-cohorts per dose level (Sub-Cohort A: eGFR >50 ml/min; Sub-Cohort B: eGFR 30–50 ml/min). Dose escalation between cohorts (150 → 300 → 450 mg/day) is prespecified; single-day dose-escalation with safety and PK assessments guiding cohort progression per protocol.
