Congratulations to Origami Therapeutics, Inc.. on their recent #SBIR Phase I award. Their project is entitled "Characterization of small molecules that lower mutant huntingtin protein as potential therapeutics for Huntington’s disease". Normal #huntingtin protein (HTT) is essential throughout the body and brain to regulate cell physiology. In patients with #Huntington’sdisease (#HD), mutant HTT (mHTT) folds abnormally, resulting in toxic mHTT fragments. Experimental procedures that lower mHTT have reversed disease symptoms in animal models of HD. However, clinical translation of treatments directed at this mechanism of action have stalled and is, in part, hypothesized to be due to nonselective lowering of both the essential HTT as well as mHTT. Origami Therapeutics has identified a small molecule, #ORI113, that prevents mHTT aggregation, and selectively lowers mHTT levels in assays employing HD patient-derived fibroblasts and iPSC-derived medium spiny neurons as well as the #YAC128 mouse model of HD. The efficacy and drug-like properties of twelve analogs of ORI-113 will be compared and lead compounds will undergo #pharmacokinetic and #brainexposure profiling following oral administration. The studies aim to identify a lead therapeutic drug candidate to move into Investigational New Drug Application studies.
