BERWYN, Pa., Dec. 05, 2023 (GLOBE NEWSWIRE) -- Annovis Bio, Inc. (NYSE: ANVS), a clinical-stage drug platform company developing novel therapies for neurodegenerative diseases today announced last patient last visit in the phase III study of its lead candidate buntanetap in patients with early Parkinson’s disease (PD). Topline data results are expected in January 2024.

"We are pleased to share the completion of our Parkinson's study which marks a significant step forward in our ongoing mission to bring new therapies for those affected by this challenging neurodegenerative disease," said Maria Maccecchini, Ph.D., Founder, President, and CEO of Annovis. “The study saw a substantial level of participation, with patients enrolling at a record pace."

"We extend our appreciation to all participants and collaborators whose contributions enabled efficient and timely completion of the study," said Melissa Gaines, Senior Vice President, Clinical Operations. “Our team now shifts its focus to diligently cleaning and analyzing the data to meet our goal of sharing the topline results early next year."

About the Phase III Trial
This study is a phase III, randomized, double-blind, placebo-controlled trial investigating the efficacy, safety, and tolerability of buntanetap for early PD patients on top of their standard of care. Patients were treated with buntanetap (10 mg or 20 mg) or placebo for 6 months. The study was initiated in August 2022 with a record pace of full enrollment in just nine months and a total of 616 screened, 523 randomized and 471 completed patients across 67 sites (43 in the United States and 24 in the European Union).   Screen failure (15%) and drop out (9.9%) rates were below projections.

About Buntanetap
Buntanetap (formerly known as Posiphen or ANVS401) attacks neurodegeneration by reducing multiple neurotoxic proteins, thereby improving synaptic transmission and axonal transport, which is the information highway of the nerve cell. Dysfunction of synaptic transmission and axonal transport has been shown to be the cause of nerve cell degeneration and ultimately death. Unlike other PD drugs in development which attempt to remove only one toxic protein, buntanetap inhibits several toxic proteins before they can form, thereby preventing the formation of all the major neurotoxic proteins responsible for PD and AD.
