Astellas Pharma Deploys Multi-Agent AI System for Manufacturing QA, Saving 980h Monthly

Astellas Pharma, a global pharmaceutical company headquartered in Tokyo, Japan and specializing in oncology, immunology, and gene therapy, deployed a multi-agent AI environment built on Microsoft Azure, Azure OpenAI Service, and Azure AI Search for manufacturing quality assurance. The system supports QA teams that previously had to manually search vast databases of past manufacturing deviation incidents to determine the correct response strategy for production batches. By synthesizing past cases into verified summaries, the multi-agent AI now delivers 81% information accuracy and 69% citation coverage, while saving QA teams approximately 980 hours monthly by automating the past-incident search and evaluation workflow. The deployment addresses compliance review for manufacturing deviations such as machine stoppages and foreign material contamination, where response speed historically depended on senior staff expertise.
