CohBar, Inc. announced topline results from the multi-center, randomized, double-blind, placebo-controlled Phase 1a/1b clinical study of CB4211, under development for nonalcoholic steatohepatitis (NASH) and obesity. The study met its primary endpoint showing that CB4211 was well-tolerated and appeared safe with no serious adverse events. Evaluation of the exploratory pharmacodynamic endpoints from the Phase 1b stage of the study comparing CB4211 to placebo demonstrated robust and significant reductions in key biomarkers of liver damage, ALT and AST, a significant decrease in glucose levels, and a trend towards lower body weight after four weeks of treatment. Both the CB4211 and placebo groups had substantial reductions in liver fat content compared to baseline. The results from both portions of the study indicate that CB4211 was well-tolerated and appeared safe with no serious adverse events. The only adverse events occurring in >10% of subjects receiving CB4211 in the four-week Phase 1b portion of the study were transient and generally mild to moderate injection site reactions. The Phase 1a stage of the study was a double blind, placebo-controlled single ascending dose and multiple ascending dose assessment of safety, tolerability, and pharmacokinetics over one week in 65 healthy adults, to select the most appropriate dose for the Phase 1b stage. The Phase 1b study was a randomized, double-blind, placebo-controlled evaluation of a 25 mg dose of CB4211 given once daily by subcutaneous injection for four weeks in 20 obese subjects with nonalcoholic fatty liver disease (NAFLD). The primary endpoints were safety and tolerability, with a secondary endpoint of pharmacokinetics, and exploratory endpoints of changes in liver fat, body weight, and biomarkers relevant to NASH, obesity, and metabolic disease. Subjects were required to have a minimum of 10% liver fat at enrollment, and to stay in the clinical study unit during the four weeks of treatment. This study was conducted at four sites. CB4211 is the first mitochondria based therapeutic to enter clinical testing. Mitochondria based therapeutics are an emerging class of drugs based on novel analogs of peptide sequences discovered by CohBar scientists in the mitochondrial genome, some of which have been shown to have the potential to regulate key processes in multiple systems and organs in the body.
