Mitofusin agonists for the treatment of neurodegenerative diseases Gerald W Dorn II, MD Mitochondria in Motion, Inc. Washington University in St Louis School of Medicine Abstract: There are a number of rare neurodegenerative diseases, including Amyotrophic Lateral Sclerosis (ALS) and Huntington’s Disease (HD), for which there is no available or effective therapy and which lead to significant morbidity and mortality in affected populations. Mitochondria in Motion, Inc. will develop and produce investigational first-in-class small molecule mitofusin agonists, under an FDA approved IND, to treat these conditions. Mitofusin agonists enhance mitochondrial fitness, metabolism, and trafficking within cells, thus improving homeostatic functioning and injury-responses of cells adversely impacted by genetic mitochondrial dysfunction. Our published disease focus for mitofusin agonists was Charcot-Marie-Tooth disease type 2A, caused by mutations in our drug’s protein target, Mitofusin 2. Here, we hypothesized that intervention with a mitofusin agonist would have beneficial effects on other genetic peripheral neuropathies with a mitochondrial component, which is supported by our preclinical data in ALS and HD patient-derived cells. Thus, we will fill an unmet healthcare need and build a commercial enterprise to serve the ~20,000 Americans with ALS and the ~150,000 Americans suffering from or at genetic risk for developing HD, their caregivers and families. In this Phase I STTR we propose to optimize the pharmacokinetic properties of mitofusin agonists for systemic administration and blood-brain-barrier penetration (Aim 1), and complete in vivo feasibility and validation studies of mitofusin agonists to delay disease progression in the well characterized SOD1G93A mouse model of ALS. Our deliverable in Phase I will be a mitofusin agonist(s) ready for STTR Phase II IND-enabling studies and validation in an expanded number of orphan diseases, to prepare for future first-in-human trials.
