FDA approves new treatment for advanced pancreatic cancer

The U.S. Food and Drug Administration has approved Onivyde (irinotecan liposome injection), in combination with fluorouracil and leucovorin, to treat patients with advanced (metastatic) pancreatic cancer who have been previously treated with gemcitabine-based chemotherapy.

The approval came Oct. 22 after Onivyde had been given Priority Review status and an orphan drug designation by the FDA, according to a news release. Priority review status is granted to applications for drugs that, if approved, would be a significant improvement in safety or effectiveness in the treatment of a serious condition. Orphan drug designation provides incentives such as tax credits, user fee waivers, and eligibility for orphan drug exclusivity to assist and encourage the development of drugs for rare diseases.

Onivyde was seen as having the potential to treat pancreatic cancer, with 48,960 new cases expected to be diagnosed in the U.S. this year along with 40,560 expected deaths, according to the National Cancer Institute. Pancreatic cancer can be difficult to diagnose early and treatment options are limited, especially when the disease has spread to other parts of the body and surgery to remove the tumor is not possible.

“Many FDA staff who review drug applications are clinicians as well, so it’s especially rewarding when we are able to expedite access to new treatments for patients with unmet needs,” Richard Pazdur, MD, director of the Office of Hematology and Oncology Products in the FDA’s Center for Drug Evaluation and Research, said in the release. “By using the Priority Review designation for the application for Onivyde, patients will have earlier access to a drug that helps extend survival.”

The effectiveness of Onivyde was demonstrated in a three-arm, randomized, open label study of 417 patients with metastatic pancreatic adenocarcinoma whose cancer had grown after receiving the chemotherapeutic drug gemcitabine or a gemcitabine-based therapy. Patients treated with Onivyde plus fluorouracil/leucovorin lived an average of 6.1 months, compared with 4.2 months for those treated with only fluorouracil/leucovorin. There was no survival improvement for those who received only Onivyde compared with those who received fluorouracil/leucovorin.

In addition, patients receiving Onivyde plus fluorouracil/leucovorin had a delay in the amount of time to tumor growth compared to those who received fluorouracil/leucovorin. The average time for those receiving Onivyde plus fluorouracil/leucovorin was 3.1 months compared with 1.5 months for those receiving fluorouracil/leucovorin.

The safety of Onivyde was evaluated in 398 patients who received either Onivyde with fluorouracil/leucovorin, Onivyde alone or fluorouracil/leucovorin. The most common side effects of treatment with Onivyde included diarrhea, fatigue, vomiting, nausea, decreased appetite, inflammation in the mouth (stomatitis) and fever (pyrexia). Onivyde was also found to result in low counts of infection-fighting cells (lymphopenia and neutropenia). Death due to sepsis following neutropenia has been reported in patients treated with Onivyde.

The labeling for Onivyde includes a boxed warning to alert healthcare professionals about the risks of severe neutropenia and diarrhea. Onivyde is not approved for use as a single agent for the treatment of patients with metastatic pancreatic cancer.

Onivyde is marketed by Merrimack Pharmaceuticals Inc. of Cambridge, Mass.
