Pharmaceutical companies face a grueling compliance bottleneck known as MLR (Medical, Legal, Regulatory review). Every marketing material (webinar slides, product brochures, social posts) must be reviewed by medical, legal, and regulatory teams before it can go live. For one client, a single product brochure was taking 14–21 days to clear MLR.
The problem wasn't the reviewers. It was the process. Materials were passed around via email chains. Version control was non-existent. Comments were scattered across PDF annotations, Slack threads, and in-person meetings. There was no audit trail, no parallel review, and no way to track whether a material was compliant, rejected, or pending.
We built a compliance workflow platform that treats MLR as a structured process rather than an unstructured approval chain. The system ingests marketing materials (PDFs, slide decks, video scripts), auto-extracts claims and assertions, then routes them through configurable review workflows.
The key innovation was our reference-checking pipeline. Marketing claims in pharma literature must cite supporting references (clinical studies, FDA labels). Our system automatically parses claims from the material, cross-references them against a connected knowledge base of approved references, and flags any claim that lacks a valid citation, before a human reviewer even sees it. This uses our PageIndex approach for fast, auditable lookups without hallucination risks.
For reviewers, we built a unified review interface that consolidates comments, version diffs, and compliance status in one place. Parallel review became the default: medical, legal, and regulatory reviewers working simultaneously, with the system tracking conflicts and escalations automatically.
Every piece of marketing material moves through the same automated pipeline before a human ever opens it: the pipeline described in the sections above, laid out end to end:
PDFs, slide decks, and video scripts uploaded into the platform.
NLP pipeline parses every marketing claim and assertion from the material.
PageIndex RAG checks each claim against the approved reference knowledge base.
Claims missing a valid citation are flagged, before a human reviewer sees the file.
Clinical accuracy and safety review.
Contractual and liability review.
FDA / compliance review.
