More than four decades on from the approval of the first biologic drug, the industry has reached a tipping point, and biotech drugs now outnumber small molecules in the global R&D pipeline. At the start of the biotech industry, progress was slow. Between 1983 and 1995, the U.S. FDA approved an average of two biologics each year. Now, biologics have taken the lead by the smallest of margins, accounting for 50.1% of drugs in development at the start of 2026, according to the Pharma Annual Review 2026, published by Pharmaprojects, a firm that tracks global pharma R&D.
