Citeline：2026年医药研发年度报告（英文版）

As of January 2026, Pharmaprojects recorded 22,940 drugs in development,a 3.9% decline from 2025's figure of 23,875. This is likely due in part to atemporary shift in Pharmaprojects reporting, which may have inflated the totalfor 2025 and suppressed 2026's total. When that factor is accounted for, the overall pipeline size has likely remained flat over the past few years
