The US FDA New Drug Approvals in August 2026
Shots:
- The US FDA approved seven novel therapies in August 2026, spanning rare diseases, oncology, neurology, hematology, and autoimmune disorders, including Orzeyful (oveporexton), Tauklarify (florquintau F 18), Zenbexus (iberdomide), Pasatru (garetosmab-grts), Rasonque (daraxonrasib), LISRAYA (brepocitinib), and Mimrylo (rusfertide).
- Key approvals introduced new treatment options across multiple high-unmet-need indications, including narcolepsy type 1, Alzheimer’s disease imaging, relapsed/refractory multiple myeloma, fibrodysplasia ossificans progressiva, metastatic pancreatic ductal adenocarcinoma, dermatomyositis, and polycythemia vera.
