Brief summary

A Phase 2, Multi-Center, Randomized, Placebo-Controlled, Dose-Finding Study Evaluating Efficacy, Safety and Tolerability of Different Doses and Regimens of Allocetra-OTS for the Treatment of Organ Failure in Adult Sepsis Patients

Detailed description

Allocetra-OTS is an immunomodulatory cell-based therapy consisting of allogeneic peripheral blood mononuclear cells that have been modified to be engulfed by macrophages and reprogram them into their homeostatic state. This is a multi-center, randomized, placebo-controlled, dose-finding study comparing the efficacy, safety and tolerability of different dosing regimens of Allocetra-OTS, in patients with sepsis. The study aims to compare the safety and efficacy of different doses and regimens of Allocetra-OTS, as well as the clinical manifestations following Allocetra-OTS treatment, to that of Placebo in the treatment of organ failure in adult sepsis patients.

Interventions

Allocetra-OTS is a cell-based therapy consisting of non-HLA-matched allogeneic peripheral blood mononuclear cells, derived from a healthy human donor following a leukapheresis procedure, induced to an apoptotic stable state and suspended in a solution containing DMSO.

Intervention model description

Up to Protocol Version 10.0, eligible patients were randomized to one of the 4 treatment groups in a 1:1:1:1 ratio between the 4 Cohorts: 1. Placebo 2. Single Intravenous (IV) dose of Allocetra-OTS, 5x10\^9 cells 3. Single IV dose of Allocetra-OTS, 10x10\^9 cells 4. Single or two IV doses of Allocetra-OTS, 10x10\^9 cells in each dose Starting from Protocol Version 10.0, patient will be randomized to either Cohort 1 (Placebo) or Cohort 4 (Single or two IV doses of Allocetra-OTS, 10x10\^9 cells in each dose).
