ANVS Annovis Bio Inc

Annovis Bio, Inc. (NYSE: ANVS), a clinical-stage drug platform company developing novel therapies for neurodegenerative diseases, today announced successful completion of data cleaning for its phase II/III study of buntanetap in patients with mild to moderate Alzheimer’s disease (AD). Topline efficacy data is expected in April.

"We are excited to share that we now move from data cleaning to organization and statistical evaluation of data for our Alzheimer’s study, which was completed in February. To clean data this fast is truly a tremendous achievement,” said Cheng Fang, Ph.D., Senior Vice President of Annovis. “The team has been working hard to provide trustworthy data, and we look forward to the topline results as we plan to announce it next month.”

The phase II/III AD study was a randomized, double-blind, placebo-controlled trial investigating the efficacy, safety, and tolerability of buntanetap in patients with mild to moderate AD. This was a dose ranging study where patients received either one of three doses of buntanetap - 7.5mg, 15mg, or 30mg - or placebo on top of their standard of care for 12 weeks. Over 700 patients were screened with a total of 353 patients enrolled and 327 patients completed the study.

“We are grateful to the participants who enrolled and completed the study as well as their caregivers and families for supporting their loved one’s involvement in this trial; we truly couldn’t do it without them. We’d also like to thank our study partners whose teamwork and dedication allowed us to complete the study in a timely fashion,” said Melissa Gaines, Senior Vice President, Clinical Operations.

About Buntanetap Buntanetap (formerly known as Posiphen or ANVS401) attacks neurodegeneration by inhibiting the formation of multiple neurotoxic proteins - amyloid beta, tau, alpha synuclein, and TDP43 - thereby improving synaptic transmission, axonal transport and neuroinflammation. Dysregulation of these pathways has been shown to be the cause of nerve cell degeneration and ultimately death. By attacking these pathways, buntanetap has the ability to reverse neurodegeneration in Alzheimer’s disease.
