ANVS Annovis Bio Inc

via IBN – Annovis Bio Inc. (NYSE: ANVS) ("Annovis" or the "Company"), a late-stage clinical drug platform company pioneering transformative therapies for neurodegenerative diseases such as Alzheimer’s disease (AD) and Parkinson’s disease (PD), today announced that the FDA has accepted an updated protocol for the pivotal Phase 3 AD study, which is slated to begin in January 2025.

In October 2024, the FDA granted clearance for Annovis to proceed with the pivotal Phase 3 AD studies based on its Phase 2/3 data demonstrating cognitive improvement in early-stage AD patients. The original protocol design proposed two separate trials: a 6-month symptomatic study and an 18-month disease-modifying study. Under the revised protocol, these studies are now integrated into a single 6/18-month trial, which will include a 6-month data readout focused on symptomatic effects, followed by an additional 12-month assessment to evaluate the disease-modifying potential of buntanetap.

“This consolidated protocol will accelerate the development timeline while maintaining the scientific rigor necessary to advance buntanetap as a treatment for AD,” said Maria Maccecchini, Ph.D., Founder, President, and CEO of Annovis. “With this design, we can leverage the 6-month symptomatic data to potentially support a New Drug Application (NDA) filing, all while continuing the same study seamlessly to assess long-term disease-modifying outcomes. We are excited to move forward with this approach, which brings us closer to delivering a novel treatment to patients in need.”
