One insight from the 2026 Orphan Drugs report

The top eight orphan drugs are projected to each surpass 6 billion dollars in global sales by 2032. Darzalex (daratumumab) leads the group, boosted by its subcutaneous formulation and an orphan‑focused change to the Inflation Reduction Act in 2025.

Darzalex helps secure Johnson & Johnson’s position as the leading orphan drug company, with nearly 31 billion dollars in expected sales in 2032. Argenx is also set to break into the top ten as the Vyvgart franchise grows toward 11 billion dollars in projected worldwide sales, placing the company ahead of Merck & Co. and Bristol Myers Squibb.
