Submission Builder

Lean content authoring across
the drug development
lifecycle

Weave Bio Submission Builder supports regulatory teams as they prepare, organize, and manage eCTD submission content across the regulatory lifecycle.
Author connected content across the dossier, from investigator’s brochures, protocols, and clinical study reports through IND, NDA, and BLA development. AI-assisted drafting, review, verification, and source traceability keep the work connected as the dossier evolves.

How it works

Author & iterate

Create and refine content with configurable AI templates grounded in source context, not disconnected prompts.

Assemble dossier

Organize content within the appropriate eCTD structure while keeping tables, citations, and cross-references connected.

Review together

Collaborate in a shared workspace where comments, context, and redlines stay together, helping teams address feedback faster.

Verify sources

Track every claim back to its source with sentence-level tracing and automated data verification for added confidence.

Export content

Prepare finalized content for publishing with section status, version control, restore, and DOCX export.

Takeda study finds Weave increases efficiency in regulatory writing

Regulatory AI should work reliably. That’s why we partnered with Takeda to ensure Weave supports your regulatory work with the precision you expect at astonishing speed.

  • Turns ~100 hours of IND nonclinical written summaries into as little as 2.6-3.7 hours
  • Independent QC assessment found no critical AI-generated regulatory errors
  • Clarity and concision are opportunities for refinement—showing how important expert human reviews are to the process
