Following a complete response letter last year, Satsuma Pharmaceuticals Inc. received U.S. FDA approval of dihydroergotamine nasal powder to treat acute migraine with or without aura. Branded Atzumi, it is the first product that uses Satsuma’s SMART (Simple MucoAdhesive Release Technology) platform that combines an advanced powder and device technology aimed at making delivery more simple.

Becoming the first treatment for rare genetic disorder Prader-Willi syndrome, breakthrough therapy drug DCCR (diazoxide choline) gained U.S. FDA approval as Vykat XR the evening before its March 27 PDUFA date, sending shares of developer Soleno Therapeutics Inc. up 38%.

Becoming the second drug approved by the U.S. FDA for tenosynovial giant cell tumors, Deciphera Pharmaceuticals Inc.’s oral CSF1R inhibitor vimseltinib, newly branded Romvimza, could take significant market share from a competitor in the same class. A phase III trial showed a higher objective response rate with Romvimza than a separate phase III trial showed with Daiichi Sankyo Co. Ltd.’s Turalio (pexidartinib), and the latter’s label contains a boxed warning on rare but serious and sometimes life-threatening liver side effects.

The U.S. FDA added hidradenitis suppurativa to the label for UCB SA’s Bimzelx (bimekizumab-bkzx), throwing renewed light on the indication, a chronic disease that causes painful, boil-like lumps that appear under the skin. Regulators cleared the humanized IL-17A and IL-17F antagonist for adults with moderate to severe HS, marking the drug’s fifth approval.

Autolus Therapuetics plc has been granted FDA approval for Aucatzyl (obecabtagene autoleucel) for the treatment of acute lymphoblastic leukemia in adults, becoming the first marketed CAR T therapy that does not have a risk evaluation and mitigation strategy attached to its label. The approval of Aucatzyl was based on results of the Felix clinical trial in relapsing/remitting ALL, which showed a strong safety profile compared to existing CAR T-cell therapies. The conduct of the trial was dogged by the COVID-19 pandemic, but of the 65 patients from an initial dosed cohort of 95 for whom efficacy was evaluated by the FDA, 63% achieved overall complete remission.

With two complete response letters in the rearview mirror, Abbvie Inc.’s Vyalev (foscarbidopa/foslevodopa) has been approved by the U.S. FDA for treating Parkinson’s disease. The drug is the first subcutaneous 24-hour infusion of levodopa-based therapy for treating motor fluctuations in adults with advanced disease.
