Weave Bio Launches NDA Workflow Designed in Partnership with Parexel; Extending AI-Native Platform Coverage Across the Full Regulatory Lifecycle

Parexel brings more than 40 years of regulatory experience and a track record of successful NDA submissions to the partnership. Through Parexel's active use of the platform for real-world NDA submissions, Weave has delivered more than 60% faster authoring timelines compared to traditional methods-without compromising quality.

Preparing an NDA means synthesizing years of clinical, non-clinical, and manufacturing data into a single, comprehensive package under intense time and quality pressure. Historically, this has meant months of manual work for regulatory teams. The Weave platform applies AI-native data extraction, document authoring, content verification, and workflow automation, freeing regulatory scientists and regulatory writers to focus on the strategic work of narrative design.

"NDA submissions are the highest-stakes moment in a drug's path to approval. Our customers deserve a platform that helps them meet that moment with speed, quality, and confidence," said Brandon Rice, Co-Founder and CEO of Weave Bio. "Today we are delivering exactly that, and having Parexel's expertise as part of this expansion is a clear signal of the standard we are building toward."

As a strategic design partner, Parexel's deep regulatory consulting expertise across clinical, non-clinical, clinical pharmacology and chemistry, manufacturing, and controls (CMC) directly informed how the Weave platform was refined to meet the demands of NDA submissions. The platform has been upgraded to support the scale and collaboration required by NDAs, in addition to new AI templates supporting NDA-specific content. While any sponsor may leverage Weave Bio's new NDA templates, Parexel will maintain a defined period of exclusivity as the only CRO with access to the co-developed templates.

"Parexel has earned its reputation by delivering the highest standard of regulatory quality for sponsors with speed and precision-including critical NDA submissions," said Paul Bridges, President, Consulting, Parexel. "Our partnership with Weave enhances that leadership by pairing our deep regulatory expertise with advanced AI that accelerates authoring and strengthens consistency across submissions."
