FDA Approves Takeda’s Exkivity for Some Lung Cancers

Share

FDA has approved Takeda’s Exkivity (mobocertinib) to treat adults with locally advanced or metastatic non-small cell lung cancer with epidermal growth factor receptor (EGFR) Exon20 insertion mutations as detected by an FDA-approved test, whose disease has progressed on or after platinum-based chemotherapy. The company says Exkivity is the only approved oral therapy specifically designed to target EGFR Exon20 insertion mutations.

Exkivity was granted priority review and received breakthrough therapy designation, fast track designation, and orphan drug designation, and was granted accelerated approval.

FDA simultaneously approved Thermo Fisher Scientific’s Oncomine Dx Target Test as a next-generation sequencing companion diagnostic to identify patients with EGFR Exon20 insertions.

The agency approval of Exkivity was based on results from the platinum-pretreated population in a Phase 1/2 trial that involved 114 patients. The most common adverse reactions were diarrhea, rash, nausea, stomatitis, vomiting, decreased appetite, paronychia, fatigue, dry skin, and musculoskeletal pain. The drug labeling includes a Boxed Warning for QTc prolongation and Torsades de Pointes, and Warnings and Precautions for interstitial lung disease/pneumonitis, cardiac toxicity, and diarrhea.

The FDA review was conducted under the FDA Oncology Center of Excellence Project Orbis.
