The U.S. Food and Drug Administration approved Opdivo or nivolumab to treat patients with advanced or metastatic renal cell carcinoma, a form of kidney cancer, who have received a certain type of prior therapy. 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.
Renal cell carcinoma is the most common form of kidney cancer in adults and forms in the tissues of the kidney that make urine. The National Cancer Institute estimates 61,560 new cases and 14,080 deaths from kidney and renal pelvis cancer in the United States this year.
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.
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.
