Treatment of Acute Traumatic Brain Injury with a Novel Cytoprotective Compound

With support from Combat Casualty Care Research Program and MTEC, Ischemix, Inc. has demonstrated the safety of their lead compound, CMX-2043, in an 80-patient double-blinded, randomized, placebo-controlled Phase 1 clinical trial.  The two-part trial tested CMX-2043 in a 40-patient single ascending dose (SAD) and a 40-patient multiple ascending dose (MAD) trial.  No serious adverse events were reported, and all treatment-emergent adverse event were mild and self-limiting. 

Traumatic Brain Injury (TBI) is a condition that is initiated by the primary injury, but is substantially compounded by secondary injuries, in which the body’s pathophysiological response to the primary insult results in further morbidity. The multi-modal capability of CMX-2043 to activate the PI3k/Akt survival signaling pathways, restore mitochondrial bioenergetics, modulate calcium overload, and reduce reactive oxygen free radical damage could provide the ideal pharmacologic intervention. CMX-2043 is a proprietary new chemical entity based on a scaffold of alpha lipoic acid, an essential cofactor for several mitochondrial energy pathways in human tissues. 

At four well-established preclinical laboratories, CMX-2043 has demonstrated safety and efficacy in two models of TBI injury in rodents and in two models of TBI injury in pigs. CMX-2043 has recently generated significant positive neuroimaging and neurobehavioral data in a six-week, multi-dose, randomized, blinded, placebo-controlled porcine TBI study of CMX-2043. Biomarker and histology results are expected later in 2023. Earlier in 2023, CMX-2043 completed a successful single and multiple ascending dose Phase 1 trial. The compound has also previously demonstrated clinical proof of concept in a cardiovascular clinical trial and has shown safety in over 400 patients exposed to the drug in clinical trials for non-TBI indications. 

 Ischemix intends to undertake a Phase 2 Proof of Concept trial in patients who have suffered a moderate-to-severe TBI. The Company also intends to develop the candidate for treatment of mild TBI (also referred to as concussion).  

Research project award recipients were selected from the respondents to MTEC’s Request for Project Proposals soliciting medical technological solutions related to MTEC’s Technology Focus Areas (Solicitation #MTEC-20-15-TBI and MTEC-19-08-MuLTI).
