AMX0035 and Progressive Supranuclear Palsy

AMX0035 is a fixed dose combination therapy designed to reduce neuronal death through blockade of key cellular death pathways originating in the endoplasmic reticulum (ER) and mitochondria. This clinical trial is designed to demonstrate that AMX0035 is safe and tolerable, and to assess its effect on disease progression as measured by the Progressive Supranuclear Palsy (PSP) Rating Scale (PSPRS) over a 52-week double-blind phase. The Phase 2b and Phase 3 study portions are planned to feature an identical design: a randomized, double-blind, placebo-controlled phase that is followed by an optional open-label extension (OLE) phase. The phase 3 portion of ORION may be initiated based on results of the phase 2b Interim Analysis and/or the Primary Analysis and the totality of data from the Phase 2b study portion.
