Opdivo (nivolumab) Demonstrates Superior Recurrence-Free Survival Versus Yervoy (ipilimumab) for Patients with Resected High-Risk Melanoma in Phase 3 CheckMate -238 Study

Opdivo decreased the risk of disease recurrence by 35% compared to Yervoy

Opdivo is the first anti-PD-1 to improve RFS and only I-O therapy to demonstrate superiority versus an active control in this patient population

Adjuvant treatment with Opdivo was well tolerated, with 14% of patients experiencing grade 3/4 adverse events and 10% discontinuing due to toxicity

PRINCETON, NJ, USA I September 10, 2017 I Bristol-Myers Squibb Company (NYSE: BMY) announced today that treatment with Opdivo (nivolumab) 3 mg/kg resulted in a significant improvement in recurrence-free survival (RFS) compared to Yervoy (ipilimumab) 10 mg/kg in patients with stage IIIb/c or stage IV melanoma following complete surgical resection. Following the July 5 announcement of topline results, detailed findings from the phase 3 CheckMate -238 study will be highlighted on September 11 during the European Society for Medical Oncology (ESMO) 2017 Congress in Madrid, Spain as part of the press program at 8:15 a.m. CEST and in Presidential Symposium 3 (LBA8) at 4:30 p.m. CEST. The results are also being published simultaneously in the New England Journal of Medicine.

At this planned interim analysis, Opdivo met its primary endpoint, showing a statistically significant improvement of 35% in RFS (HR 0.65; 97.56% CI: 0.51 to 0.83; p <0.0001) compared to Yervoy. The 18-month RFS rates for the Opdivo and Yervoy groups, respectively, were 66.4% (95% CI: 61.8 to 70.6) and 52.7% (95% CI: 47.8 to 57.4). Median RFS had not yet been reached for either group at the time of this analysis. This benefit was consistent across key subgroups, including BRAF mutated and BRAF wildtype patients, and no new safety signals were identified in this trial.

“Despite the rapid development of promising new options for advanced melanoma patients in recent years, those patients with high-risk, resectable melanoma still face a poor prognosis and have an unmet need for more effective adjuvant treatments,” said Jeffrey S. Weber, M.D., Ph.D., deputy director of the Laura and Isaac Perlmutter Cancer Center at NYU Langone Health, and Professor of Medicine at NYU School of Medicine. “The significant RFS results observed with Opdivo in CheckMate -238 are encouraging and provide physicians with new insights into the potential of Opdivo for the management of adjuvant melanoma.”

Adverse events (AEs) leading to discontinuation were reported in 9.7% of subjects in the Opdivo arm compared to 42.6% of patients in the Yervoy group. Treatment-related grade 3/4 AEs were experienced by 14.4% of patients in the Opdivo group and 45.9% in the Yervoy group. The most common all-cause AEs leading to discontinuation in the Opdivo arm were diarrhea (1.5%) and colitis (1.1%). In the Yervoy arm, the most common AEs leading to discontinuation were diarrhea (10.2%), colitis (8.2%), hypophysitis (4.2%), alanine aminotransferase increase (3.5%), aspartate aminotransferase increase (2.9%), hepatitis (1.5%) and pneumonitis (1.5%). There were no treatment-related deaths reported in the Opdivo group and two treatment-related deaths reported in the Yervoy arm that occurred more than 100 days after treatment.

“These data show Opdivo as the first PD-1 to significantly improve RFS and the only I-O agent to demonstrate superior results, including better tolerance, as compared to an active control, in the treatment of adjuvant melanoma,” said Vicki Goodman, M.D., head of new asset development, Bristol-Myers Squibb. “These results build upon the significant treatment advance we saw with Yervoy in an adjuvant setting and speak to our leadership and commitment to cancer research through innovative approaches including exploring much-needed treatment options to address earlier stages of disease.”

About CheckMate -238

CheckMate -238 is an ongoing phase 3, randomized double-blind study of Opdivo versus Yervoy in patients who have undergone complete resection of stage IIIb/c or stage IV melanoma. The trial randomized 906 patients 1:1 to receive either Opdivo 3 mg/kg intravenously (IV) every two weeks or Yervoy 10 mg/kg IV every three weeks for four doses and then every 12 weeks starting at week 24. Patients were treated until disease recurrence, unacceptable toxicity or consent withdrawal for up to one year. The primary endpoint is RFS defined as the time between randomization and the date of first recurrence or death.

Adjuvant Therapy in Melanoma

Melanoma is separated into five staging categories (stages 0 to 4) based on the in-situ feature, thickness and ulceration of the tumor, whether the cancer has spread to the lymph nodes, and how far the cancer has spread beyond lymph nodes.

Stage 3 melanoma has reached the regional lymph nodes but has not yet spread to distant lymph nodes or to other parts of the body (metastasized), and requires surgical resection of the primary tumor as well as the involved lymph nodes. Some patients may also be treated with adjuvant therapy. Despite surgical intervention and possible adjuvant treatment, most patients experience disease recurrence and progress to metastatic disease. By five years, the majority of stage IIIb and IIIc patients (68% and 89%, respectively) experience disease recurrence.

Bristol-Myers Squibb & Immuno-Oncology: Advancing Oncology Research

At Bristol-Myers Squibb, patients are at the center of everything we do. Our vision for the future of cancer care is focused on researching and developing transformational Immuno-Oncology (I-O) medicines for hard-to-treat cancers that could potentially improve outcomes for these patients.

We are leading the scientific understanding of I-O through our extensive portfolio of investigational compounds and approved agents. Our differentiated clinical development program is studying broad patient populations across more than 50 types of cancers with 14 clinical-stage molecules designed to target different immune system pathways. Our deep expertise and innovative clinical trial designs position us to advance I-O/I-O, I-O/chemotherapy, I-O/targeted therapies and I-O radiation therapies across multiple tumors and potentially deliver the next wave of therapies with a sense of urgency. We also continue to pioneer research that will help facilitate a deeper understanding of the role of immune biomarkers and how patients’ tumor biology can be used as a guide for treatment decisions throughout their journey.

We understand making the promise of I-O a reality for the many patients who may benefit from these therapies requires not only innovation on our part but also close collaboration with leading experts in the field. Our partnerships with academia, government, advocacy and biotech companies support our collective goal of providing new treatment options to advance the standards of clinical practice.

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 enrolled more than 25,000 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 60 countries, including the United States, the European Union and Japan. 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.
