Here is a look back at the FDA happenings from the month of December 2023.
December 2023 was a busy month for the field of oncology as the FDA granted 4 approvals, including pirtobrutinib (Jaypirca) for previously treated chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL/SLL), belzutifan (Welireg) for advanced renal cell carcinoma (RCC), enfortumab vedotin-ejfv (Padcev) plus pembrolizumab (Keytruda) for locally advanced or metastatic urothelial cancer, and eflornithine (Iwilfin) to reduce the risk of relapse in patients with high-risk neuroblastoma.
In addition to these approved agents, the FDA cleared 4 investigational new drug applications, granted 2 breakthrough drug designations and 1 fast track designation, and gave 3 drugs priority review across cancer types.
Notably, the FDA also issued a complete response letter to the biologics license application seeking the approval of cosibelimab for patients with metastatic or locally advanced cutaneous squamous cell carcinoma and rejected the new drug application for sotorasib for the treatment of locally advanced or metastatic KRAS G12C-mutated non–small cell lung cancer.
