FDA Priority Review for Boehringer Gilotrif sNDA

Share

In its fourth major decision since May for drug products aimed at non-small cell lung cancer (NSCLC), FDA has accepted for priority review a Boehringer Ingelheim supplemental NDA for Gilotrif (afatinib) that seeks an indication for first-line treatment of certain patients with metastatic NSCLC whose tumors have epidermal growth factor receptor (EGFR) exon 21 (L861Q), G719X or S768I substitution mutations as detected by an agency-approved test. The other three decisions involved AstraZeneca’s Tagrisso (osimertinib) and Imfinzi (durvalumab), and Novartis’ Zykadia (ceritinib).

 

Gilotrif is already approved for first-line treatment of patients with NSCLC whose tumors have EGFR exon 19 deletions or exon 21 (L858R) mutations, and squamous cell carcinoma of the lung whose disease has progressed after treatment with platinum-based chemotherapy. The submission is based on a meta-analysis of three clinical trials from the LUX-Lung clinical trial program that examined the efficacy of Gilotrif in patients whose tumors have uncommon EGFR mutations. The company says that the efficacy outcomes evaluated in the study included: objective response, disease control, duration of response, progression-free survival and overall survival.
