Results represent longest follow-up to date for dual Immuno-Oncology (I-O) therapy in a Phase 3, randomized, controlled trial

PRINCETON, NJ, USA I September 28, 2019 IBristol-Myers Squibb Company (NYSE: BMY) today announced five-year results from the Phase 3 CheckMate -067 clinical trial, which continues to demonstrate improved overall survival with the first-line combination of Opdivo (nivolumab) plus Yervoy (ipilimumab), versus Yervoy alone, in patients with advanced metastatic melanoma. With a minimum follow-up of 60 months (five years), five-year overall survival rates were 52% for the Opdivo plus Yervoy combination, 44% for Opdivo alone, and 26% for Yervoy alone. Data from CheckMate -067 will be featured in the official Press Programme and in a Proffered Paper session at the European Society for Medical Oncology (ESMO) 2019 Congress in Barcelona, Spain (Presentation #LBA68_PR; Saturday, September 28 at 8:30 AM CEST) and simultaneously published in The New England Journal of Medicine.

The safety profile for Opdivo plus Yervoy was consistent with prior findings, with no new safety signals and no additional treatment-related deaths. At this five-year analysis, treatment-related adverse events were consistent with those previously reported and occurred in 300 (96%) patients in the combination group, 271 (87%) patients in the Opdivo group, and 268 (86%) patients in the Yervoy group; grade 3/4 adverse events occurred in 186 (59%), 73 (23%), and 86 (28%) patients, respectively.

The percentage of patients experiencing an objective response remained stable at 58% for Opdivo plus Yervoy, 45% for Opdivo alone, and 19% for Yervoy, while the percentage of patients experiencing a complete response continued to increase, with complete response rates at five years of 22% for Opdivo plus Yervoy, 19% for Opdivo alone, and 6% for Yervoy alone. In addition, the proportion of patients alive and treatment-free was 74% in the Opdivo plus Yervoy group and 58% and 45% for Opdivo alone and Yervoy alone, respectively.

Among patients with BRAF-mutant or wild-type tumors, the rate of overall survival at five years was 60% and 48%, respectively, in patients who received Opdivo plus Yervoy; 46% and 43% for Opdivo alone; and 30% and 25% for Yervoy alone. Health-related quality of life continued to be maintained during or following treatment with Opdivo alone or the combination of Opdivo plus Yervoy.

“Historically, positive five-year survival outcomes for patients with metastatic melanoma have been difficult to achieve,” said James Larkin, FRCP, Ph.D., CheckMate -067 lead investigator and Consultant Medical Oncologist at The Royal Marsden NHS Foundation Trust. “Now, with over half of patients treated with the nivolumab plus ipilimumab combination surviving to five years, and 74% of surviving patients remaining treatment-free, we have set a new and encouraging precedent.”

“The sustained long-term efficacy seen in the five-year CheckMate -067 data demonstrates the importance of dual Immuno-Oncology therapy,” said Arvin Yang, M.D., Ph.D., development lead, Melanoma and Genitourinary Cancers, Bristol-Myers Squibb. “This five year milestone represents exciting progress in delivering on our mission to significantly increase survival rates and maintain quality of life for patients with cancer across tumor types.”

About CheckMate -067

CheckMate -067 is a Phase 3, double-blind, randomized trial that evaluated the combination of Opdivo plus Yervoy or Opdivo monotherapy versus Yervoy monotherapy in 945 patients with previously untreated advanced melanoma. Patients in the combination group (n=314) received Opdivo 1 mg/kg plus Yervoy 3 mg/kg (Q3W) for four doses followed by Opdivo 3 mg/kg every two weeks (Q2W). Patients in the Opdivo monotherapy group (n=316) received Opdivo 3 mg/kg Q2W plus placebo. Patients in the Yervoy monotherapy group (n=315) received Yervoy 3 mg/kg every three weeks for four doses plus placebo. Patients were treated until progression or unacceptable toxic effects. Overall survival (OS) and progression-free survival (PFS) were co-primary endpoints of the trial. Secondary endpoints included objective response rates (ORR), efficacy by tumor PD-L1 expression level and safety.

About Metastatic 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. The incidence of melanoma has been increasing steadily for the last 30 years. In the United States, 192,310 new diagnoses of melanoma and more than 7,230 related deaths are estimated for 2019. Globally, the World Health Organization estimates that by 2035, melanoma incidence will reach 424,102, with 94,308 related deaths. Melanoma is mostly curable when treated in its very early stages; however, survival rates are roughly halved if regional lymph nodes are involved. Patients in the United States diagnosed with advanced melanoma classified as Stage IV historically have a five-year survival rate of 15% to 20% and 10-year survival of about 10% to 15%.

Bristol-Myers Squibb: Advancing Oncology Research

At Bristol-Myers Squibb, patients are at the center of everything we do. The focus of our research is to increase quality, long-term survival for patients and make cure a possibility. Through a unique multidisciplinary approach powered by translational science, we harness our deep scientific experience in oncology and Immuno-Oncology (I-O) research to identify novel treatments tailored to individual patient needs. Our researchers are developing a diverse, purposefully built pipeline designed to target different immune system pathways and address the complex and specific interactions between the tumor, its microenvironment and the immune system. We source innovation internally, and in collaboration with academia, government, advocacy groups and biotechnology companies, to help make the promise of transformational medicines, like I-O, a reality for patients.

About Opdivo

Opdivo is a programmed death-1 (PD-1) immune checkpoint inhibitor that is designed to uniquely harness the body’s own immune system to help restore anti-tumor immune response. By harnessing the body’s own immune system to fight cancer, Opdivo has become an important treatment option across multiple cancers.

Opdivo’s leading global development program is based on Bristol-Myers Squibb’s scientific expertise in the field of Immuno-Oncology, and includes a broad range of clinical trials across all phases, including Phase 3, in a variety of tumor types. To date, the Opdivo clinical development program has treated more than 35,000 patients. The Opdivo trials have contributed to gaining a deeper understanding of the potential role of biomarkers in patient care, particularly regarding how patients may benefit from Opdivo across the continuum of PD-L1 expression.

In July 2014, Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world. Opdivo is currently approved in more than 65 countries, including the United States, the European Union, Japan and China. In October 2015, the Company’s Opdivo and Yervoy combination regimen was the first Immuno-Oncology combination to receive regulatory approval for the treatment of metastatic melanoma and is currently approved in more than 50 countries, including the United States and the European Union.
