Annovis Announces Partnership with Weave Bio, AI Regulatory Platform, in Preparation of NDA for Buntanetap in Alzheimer’s Disease

Annovis Bio, Inc. (NYSE: ANVS) (“Annovis” or the “Company”), a Phase 3 clinical-stage biotechnology company developing the investigational oral therapy, buntanetap, for neurodegenerative diseases such as Alzheimer’s disease (AD) and Parkinson’s disease (PD), today announced a collaboration with Weave Bio, an AI platform for regulatory content and knowledge management, in support of the planned New Drug Application (NDA) for buntanetap.

Under the collaboration, Annovis will use Weave for drafting, reviewing and managing the NDA documents as the Company heads toward a 6-month top-line data readout from the pivotal Phase 3 AD trial – the data that will form the basis of the submission. Annovis’ regulatory and clinical teams will retain full responsibility for content, verification and final approval of every document submitted to the U.S. Food and Drug Administration (FDA).

"Our goal is to have most of the NDA ready before the data readout, so the path from the top-line results to filing is as short as possible," said Eve Damiano, Senior VP, Regulatory Operations at Annovis. "Weave will let our regulatory team spend time on scientific judgment and strategy while providing essential assistance on assembling documents in a faster and more organized way. That is a meaningful advantage as we prepare a submission for an investigational therapy we believe has the potential to help millions of patients still waiting for a treatment that can change their lives."

The collaboration follows the completion of enrollment in Annovis’ pivotal Phase 3 AD study ( NCT06709014 ), which enrolled 862 biomarker-confirmed patients, exceeding the original target of 760. The Company aims to reach the database lock for the 6-month treatment period in December 2026, followed by the top-line symptomatic data announcement in March 2027.

“Annovis is exactly the kind of company our platform was built for – a team with deep scientific expertise, ambitious timelines, and a vision for the future of AI-driven drug development,” said Brandon Rice, CEO and co-founder of Weave Bio. “NDA submissions are not just about writing documents, they are about weaving years of scientific knowledge into a coherent, traceable narrative. We are privileged to help Annovis do that for a disease area that still has no effective treatment.”

Annovis and Weave Bio have aligned their approach around the FDA’s guidance on the use of AI to support regulatory decision-making, issued in January 2025, keeping regulatory professionals in control of AI-assisted drafting, extraction, traceability and review.
