About Pfizer
Pfizer is a leading organisation in the pharmaceuticals & life sciences sector. Like most pharmaceuticals & life sciences organisations at scale, they faced growing operational complexity — more volume, higher expectations, and a workforce stretched thin by routine but critical tasks.
The Problem
Pfizer's regulatory affairs teams faced the challenge of producing high-quality NDA/BLA submissions faster, while ensuring accuracy across complex scientific documentation that could span tens of thousands of pages.
How They Used Claude
Pfizer partnered with Anthropic to deploy Claude for regulatory document analysis, clinical study report summarisation, and submission section drafting. Claude processes entire CTD modules and generates first-draft narratives that regulatory writers then refine.
Measurable Outcomes
- ✓ Regulatory submission drafting time reduced by 60%
- ✓ Clinical study report summaries generated in 2 hours vs 2 weeks manually
- ✓ Cross-reference consistency in regulatory documents improved to 99.7%
- ✓ Scientific writers report 40% more time available for high-value strategic work
"Claude's ability to maintain scientific accuracy while processing the volume of documentation required for global regulatory submissions is transformative."

Key Lessons for Pharmaceuticals & Life Sciences Organisations
Start with a clearly scoped pilot — one use case, one team, 30 days.
Measure baseline metrics before deployment so ROI is unambiguous.
Executive sponsorship drives adoption; middle management drives usage.
Invest in training alongside technology — adoption is 80% people, 20% product.
