Prana Releases Successful Phase 2 Results in HSG Trial Reach2HD

Prana Biotechnology released promising results from its phase 2 study of PBT2 in individuals with mild to moderate Huntington disease, Reach2HD. In a randomized, double-blind, placebo-controlled study, 104 (95%) of 109 study participants completed the 26-week study on one of the three study arms – PBT2 250mg daily, PBT2 100mg daily, or placebo. Serious adverse events were more common in those on active drug (nine) than on placebo (one), but only one was deemed by site investigators to be related to study drug.
