The trial evaluates the safety and efficacy of one and two doses of the study drug, Allocetra-OTS, in patients who have been diagnosed with sepsis.

The study drug, Allocetra-OTS is a cell-based therapeutic composed of donor apoptotic cells. The product contains allogeneic mononuclear enriched cells in the form of a liquid suspension with at least 40% early apoptotic cells. The study drug, Allocetra-OTS, is based on the known activity of apoptotic cells to contribute to maintenance of peripheral immune homeostasis. As altered immune response is associated with organ dysfunction in sepsis, the possibility is being tested that the study drug can improve the condition of sepsis.

Inclusion Criteria:

• Suspected, presumed or documented infection from any source.
• Initiation of antibiotics.
• Meets Sepsis 3 criteria: The presence of organ dysfunction as identified by a total SOFA score ≥ 2 points above baseline.
