Pemetrexed Injection Granted FDA Approval for Nonsquamous NSCLC and Malignant Pleural Mesothelioma

The FDA has granted approval to injectable pemetrexed (Pemfexy) for the treatment of patients with locally advanced or metastatic nonsquamous non—small cell lung cancer (NSCLC) and for those with malignant pleural mesothelioma.Pemetrexed for injection is an alternative to standard pemetrexed (Alimta).

The indication for the new formulation is for use in combination with cisplatin for patients with locally advanced or metastatic nonsquamous NSCLC; locally advanced or metastatic nonsquamous NSCLC whose disease has not progressed after 4 cycles of platinum-based first-line chemotherapy, as maintenance treatment; locally advanced or metastatic nonsquamous NSCLC after prior chemotherapy as a single agent; and for patients with malignant pleural mesothelioma whose disease is unresectable or who are otherwise ineligible for curative surgery in combination with cisplatin.

“We are pleased to receive final approval from FDA and look forward to making Pemfexy available to the patients who can benefit,” Scott Tarriff, chief executive officer of Eagle Pharmaceuticals, the developer of pemetrexed for injection, stated in a press release. “Our initial market exclusivity for Pemfexy represents a significant opportunity for Eagle and builds on the successes of our expanding presence in the oncology space."

The pemetrexed injection is a ready-to-dilute formulation that received tentative approval from the FDA in 2017. The company stated that the agency concluded that the injection met all required quality, safety and efficacy standards. However, at the time, the product was not eligible for marketing in the United States due to existing patent protections.

The approval follows a settlement agreement reached between Eagle Pharmaceuticals and Eli Lilly and Company, the latter of which manufactures standard pemetrexed.
