Phase 3 First-Line Melanoma Study of Nivolumab, an Investigational PD-1 Checkpoint Inhibitor, Demonstrates Superior Overall Survival
PRINCETON, N.J.--(BUSINESS WIRE)--Tuesday, June 24, 2014 - Bristol-Myers Squibb Company (NYSE:BMY) today announced that a randomized blinded comparative Phase 3 study evaluating nivolumab versus dacarbazine (DTIC) in patients with previously untreated BRAF wild-type advanced melanoma was stopped early because an analysis conducted by the independent Data Monitoring Committee (DMC) showed evidence of superior overall survival in patients receiving nivolumab compared to the control arm. Patients in the trial will be unblinded and allowed to cross over to nivolumab. The Company will share these data with health authorities.
“The outcome of CheckMate -066 is an important milestone in the field of immuno-oncology as it represents the first well-controlled, randomized Phase 3 trial of an investigational PD-1 checkpoint inhibitor to demonstrate an overall survival benefit,” said Michael Giordano, MD, Head of Oncology Development. “Bristol-Myers Squibb is committed to continuing to lead advances in immuno-oncology and to executing our strategy to provide patients with the best opportunity to achieve the potential for long term survival.”
CheckMate -066 investigators have been informed of the decision to stop the blinded comparative portion of the trial. Bristol-Myers Squibb will ensure that patients are informed of the opportunity to continue or start treatment with nivolumab in an open-label extension as part of the Company’s commitment to characterize long-term survival. The study, which was designed in consultation with the Committee for Medicinal Products for Human Use (CHMP), was primarily conducted in countries where DTIC is a commonly-used treatment in the first-line setting, including Canada, but not at U.S. trial sites. The Company will complete a full evaluation of the final CheckMate -066 data and work with investigators on the future presentation and publication of the results.
About the Study
CheckMate -066 is a Phase 3 randomized, double-blind study of patients with previously untreated BRAF wild-type unresectable Stage III and IV melanoma. The trial enrolled 418 patients who were randomized to receive either nivolumab 3 mg/kg every two weeks or DTIC 1000 mg/m2 every three weeks. The primary endpoint was overall survival. Secondary endpoints included progression free survival and objective response rate.
Cancer cells may exploit “regulatory” pathways, such as checkpoint pathways, to hide from the immune system and shield the tumor from immune attack. Nivolumab is an investigational, fully-human PD-1 immune checkpoint inhibitor that binds to the checkpoint receptor PD-1 (programmed death-1) expressed on activated T-cells. We are investigating whether by blocking this pathway, nivolumab would enable the immune system to resume its ability to recognize, attack and destroy cancer cells.
Bristol-Myers Squibb has a broad, global development program to study nivolumab in multiple tumor types consisting of more than 35 trials – as monotherapy or in combination with other therapies – in which more than 7,000 patients have been enrolled worldwide. Among these are several potentially registrational trials in non-small cell lung cancer melanoma, renal cell carcinoma (RCC), head and neck cancer, glioblastoma and non-Hodgkin lymphoma. In 2013, the FDA granted Fast Track designation for nivolumab in NSCLC, melanoma and RCC. In May 2014, the FDA granted nivolumab Breakthrough Therapy Designation for the treatment of patients with Hodgkin lymphoma after failure of autologous stem cell transplant and brentuximab.
About Advanced Melanoma
Melanoma is a form of skin cancer characterized by the uncontrolled growth of pigment-producing cells (melanocytes) located in the skin. Metastatic melanoma is the deadliest form of the disease, and occurs when cancer spreads beyond the surface of the skin to other organs, such as the lymph nodes, lungs, brain or other areas of the body. The incidence of melanoma has been increasing for at least 30 years. In 2012, an estimated 232,130 melanoma cases were diagnosed globally. Melanoma is mostly curable when treated in its early stages. However, in its late stages, the average survival rate has historically been just six months with a one-year mortality rate of 75%, making it one of the most aggressive forms of cancer.
Immuno-Oncology at Bristol-Myers Squibb
Surgery, radiation, cytotoxic or targeted therapies have represented the mainstay of cancer treatment over the last several decades, but long-term survival and a positive quality of life have remained elusive for many patients with advanced disease.
To address this unmet medical need, Bristol-Myers Squibb is leading advances in a rapidly evolving field of cancer research and treatment known as immuno-oncology, which involves agents whose primary mechanism is to work directly with the body’s immune system to fight cancer. The company is exploring a variety of compounds and immunotherapeutic approaches for patients with different types of cancer, including researching the potential of combining immuno-oncology agents that target different and complementary pathways in the treatment of cancer.
Bristol-Myers Squibb is committed to advancing the science of immuno-oncology, with the goal of changing survival expectations and the way patients live with cancer.
