FDA approves Opdivo to treat advanced form of kidney cancer

Opdivo works by targeting the cellular pathway known as PD-1/PD-L1 (proteins found on the body’s immune cells and some cancer cells). By blocking this pathway, Opdivo may help the body’s immune system fight cancer cells. Opdivo is intended for use in renal cell carcinoma in patients who have received prior anti-angiogenic therapy (treatments that interfere with the blood vessels that contribute to the growth of cancerous cells).

The safety and efficacy of Opdivo for this use were demonstrated in an open-label, randomized study of 821 patients with advanced renal cell carcinoma whose disease worsened during or after treatment with an anti-angiogenic agent. Patients were treated with Opdivo or another type of kidney cancer treatment called everolimus (marketed as Afinitor). Those treated with Opdivo lived an average of 25 months after starting treatment compared to 19.6 months in those treated with Afinitor. This effect was observed regardless of the PD-L1 expression level of patients’ renal cell tumors. Additionally, 21.5 percent of those treated with Opdivo experienced a complete or partial shrinkage of their tumors, which lasted an average of 23 months, compared to 3.9 percent of those taking Afinitor, lasting an average of 13.7 months.

The most common side effects of Opdivo for this use are conditions relating to abnormal weakness or lack of energy (asthenic conditions), cough, nausea, rash, difficulty breathing (dyspnea), diarrhea, constipation, decreased appetite, back pain and joint pain (arthralgia).

Opdivo also has the potential to cause serious side effects that result from the immune system effect of Opdivo (known as “immune-mediated side effects”). These severe immune-mediated side effects involve healthy organs, including the lung, colon, liver, kidneys, hormone-producing glands and the brain.

The FDA granted the Opdivo application a breakthrough therapy designation, fast track designation, and priority review status. These are distinct programs intended to facilitate and expedite the development and review of certain new drugs in light of their potential to benefit patients with serious or life-threatening conditions.

Opdivo is marketed by Bristol-Myers Squibb based in Princeton, New Jersey. Torisel is marketed by Pfizer, based in New York, New York. Afinitor is marketed by Novartis Pharmaceuticals of East Hanover, New Jersey.

The FDA, an agency within the U.S. Department of Health and Human Services, protects the public health by assuring the safety, effectiveness, and security of human and veterinary drugs, vaccines and other biological products for human use, and medical devices. The agency also is responsible for the safety and security of our nation’s food supply, cosmetics, dietary supplements, products that give off electronic radiation, and for regulating tobacco products.
