Enlivex Mixed Results of Sepsis Cell Therapy
Enlivex Therapeutics says there were mixed results from its Phase 2 study of Allocetra in patients with sepsis, in which 120 patients enrolled. The company says it is developing Allocetra as a universal, off-the-shelf cell therapy designed to reprogram macrophages into their homeostatic state. “Diseases such as solid cancers, sepsis, and many others reprogram macrophages out of their homeostatic state,” it says.
Study investigator Bruno François, an intensive care physician and head of the Limoges Clinical Investigation Center (Limoges, France) had this to say: “The study was well designed and executed, although randomization resulted in the Allocetra-treated cohorts having higher frequencies of septic shock and invasive ventilation prior to treatment, as compared with the control group. Because these patient attributes are typically associated with a significantly higher degree of difficulty of treatment and higher mortality rates, the relative effect of Allocetra in some patient subpopulations was challenging to deduce. I am pleased with the unusually low mortality rates across the board in the study, and that Allocetra demonstrated a potential indication of effect in high-risk sepsis patients originating from urinary tract infections.”
Enlives CEO Oren Hershkovitz also acknowledged the “biases” in the study that made it challenging to deduce the relative effect in other patient subgroups. The company intends to “consider, upon reviewing the totality of the data, a potential follow-on, randomized, controlled study of a solely high-risk UTI sepsis population.” He said up to 31% of sepsis cases start as UTIs, and this represents a substantial potential market opportunity for Allocetra.
