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

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.
