Background: Pharmaceutical research and development requires coordination across dozens of specialized domains, yet traditional approaches rely on sequential handoffs between functional teams, creating delays and information loss. Objective: We developed Pharma Agents, a multi-agent AI system that orchestrates 53+ specialized pharmaceutical domain experts for evidence-driven drug development. Methods: The system was designed with 15+ functional modules covering basic research, CMC, quality, regulatory affairs, pharmacology, bioanalysis, toxicology, biologics, ADC development, and clinical strategy. Each query engages 3+ domain experts simultaneously with transparent reasoning trails. Results: The system has been deployed to support CRO operations including small molecule synthesis design, peptide drug development, antibody developability assessment, IND filing strategy, FIH clinical protocol design, and GMP audit preparation. The platform processes queries with an average of 3-5 expert agents per task, producing academic-quality reports with full chain-of-thought transparency. Conclusions: Pharma Agents demonstrates that multi-agent AI systems can effectively orchestrate specialized pharmaceutical expertise across the drug development value chain, providing a new paradigm for evidence-driven translational medicine.
