FDA Clears Annovis to Launch Pivotal Phase 3 Alzheimer’s Studies, Paving the Way to NDAs


Annovis Bio Inc. recently announced the successful outcome of the End-of-Phase 2 meeting with the US FDA on October 10, 2024. During the meeting, the FDA granted clearance to proceed with pivotal Phase 3 studies, based on the company’s Phase 2/3 clinical data showing symptomatic improvement in early AD patients. Annovis and the FDA have now aligned on a development path for buntanetap towards the filing of New Drug Applications (NDAs), one for short-term and one for long-term efficacy.

The Phase 3 program will investigate buntanetap in patients with early AD and will consist of two trials: a 6-month study aimed at confirming buntanetap’s symptomatic effects and an 18-month study designed to demonstrate potential disease-modifying effects. While the company plans to run both studies, the completion of a well-designed and well-executed 6-month trial may be sufficient to support an NDA filing, potentially within one year of the study’s initiation.

Additionally, the FDA raised no concerns about the company’s data on buntanetap’s safety, including liver enzymes, drug interactions, dose selection, pharmacokinetics, and population pharmacokinetics and confirmed that development can proceed using the new crystal form of buntanetap.

“We are now ready to move into the highly anticipated Phase 3 stage,” said Maria Maccecchini, PhD, Founder, President, and CEO of Annovis Bio. “Our priority is to bring the treatment to patients as early as possible, and we are committed to ensuring the next clinical trial is executed at the highest standards to attain an expedited NDA submission. Our team is already preparing for trial initiation early next year and will continue to keep you updated as we advance towards our goal.”
