Enlivex Therapeutics Announces Plan for Increased Production Capacity of Allocetra in Preparation for Potential Treatment of Coronavirus (COVID-19) Patients with Organ Failure

Nes-Ziona, Israel, Feb. 24, 2020 (GLOBE NEWSWIRE) -- Enlivex Therapeutics Ltd. (Nasdaq: ENLV), a clinical-stage immunotherapy company, today announced that it is initiating a plan to increase its manufacturing capacity of AllocetraTM, following the first confirmed coronavirus (COVID-19) case in Israel, in preparation for potential requests for treatment of coronavirus (COVID-19) patients who are hospitalized with diagnosed organ dysfunctions or failures related to coronavirus.

AllocetraTM is an experimental therapy being investigated for treatment of patients with organ failure associated with sepsis, a syndrome whose lethal pathophysiology - cytokine storm followed by organ failure - is similar to that of the coronavirus (COVID-19).

Sepsis is the 3rd leading cause of mortality in the United States. One of every three patients who die in U.S. hospitals dies from sepsis. Organ failure resulting from sepsis, as well as in coronavirus (COVID-19), is considered the result of an exaggerated response of the immune system ("cytokine storm") in the human body to an infection by a virus or a bacteria.

This exaggerated immune response results in organ damage. The immune attacks typically occur in vital organs such as lungs, heart, kidney and liver. When the organs become distressed, they begin to slowly dysfunction, which can result in organ failure, multiple organ failure, and mortality. Mortality rates from sepsis vary upon the degree of organ failure with which the patient arrived at the hospital. The literature describes an average of 20-40% mortality within 28-90 days for sepsis patients admitted to the ICU in a state of organ failure. Similarly, a cytokine storm was recently reported in patients with COVID-19 that were hospitalized in the ICU, (Huang et al. www.thelancet.com Published online January 24, 2020 https://doi.org/10.1016/S0140-6736(20)30183-5) and patients admitted to ICU had higher plasma levels of cytokines and chemokines.

There is no currently approved treatment for sepsis or for complicated corona virus infections. Enlivex recently announced the interim results from its first clinical trial in patients with sepsis.  When compared with matched historical controls with sepsis from the same hospital, there were clear differences in (i) mortality -- none of the six Allocetra-treated patients died, vs 29% mortality in 28 days for the matched controls group; (ii) organ failure measures - 78% of the matched controls had an increase of organ failure markers post admission to the hospital, while none (0%) of the six treated patients had any increase in organ failure score, despite similar presentation, and the average organ failure state of the matched controls worsened by a factor of two, while the treated group had not a single case of any organ failure increase; (iii) all the treated patients had their organ failures eliminated and they were subsequently released from the hospital. Each of the patients had organ dysfunction in two to five systems prior to administration of Allocetra. A Full summary of this trial is expected to be published in March 2020.

Enlivex has publicly announced its plan to initiate in 2020 two clinical studies: (i) a Phase II/III clinical trial for sepsis later in the year, and (ii) a Phase II/III for the prevention of GvHD in patients who undergo bone-marrow transplantations. The manufacturing capacity of Allocetra was planned to match the expected recruitment rate of patients in those two clinical trials.

To accommodate potential requests for treatment of COVID-19 patients who are hospitalized with diagnosed organ dysfunctions and/or failures, Enlivex has initiated a plan to increase the production capacity of Allocetra.

ALLOCETRATM by Enlivex was designed to provide a novel immunotherapy mechanism of action that targets life-threatening clinical indications that are defined as "unmet medical needs", including prevention or treatment of complications associated with bone marrow transplantations (BMT) and/or hematopoietic stem cell transplantations (HSCT); organ dysfunction and acute multiple organ failure associated with sepsis; and enablement of an effective treatment of solid tumors via immune checkpoint rebalancing.


Enlivex is a clinical stage immunotherapy company, developing an allogeneic drug pipeline for immune system rebalancing. Immune system rebalancing is critical for the treatment of life-threatening immune and inflammatory conditions which involve an out of control immune system (e.g. Cytokine Release Syndrome) and for which there are no approved treatments (unmet medical needs), as well as solid tumors immune-checkpoint rebalancing.  For more information, visit http://www.enlivex.com.
