PRINCETON, NJ, USA I September 10, 2017 I Bristol-Myers Squibb Company (NYSE:BMY) announced today results from the Phase 3 CheckMate -214 trial evaluating Opdivo (nivolumab) plus Yervoy (ipilimumab) versus sunitinib in patients with previously untreated advanced or metastatic renal cell carcinoma (RCC), including data on key subgroups. With a minimum follow-up of 17.5 months, Opdivo in combination with Yervoy reduced the risk of death 37% [HR 0.63; 99.8% CI: 0.44 to 0.89; P < 0.0001] compared with sunitinib, the current standard of care, in an interim analysis of overall survival (OS) in intermediate- and poor-risk patients, the co-primary endpoint. The median OS had not yet been reached for the combination and was 26 months for sunitinib (95% CI: 22.1 to NA). Results from CheckMate -214 will be presented today during Presidential Symposium II at the European Society for Medical Oncology (ESMO) 2017 Congress in Madrid, Spain, from 5:55-6:10 PM CEST in the Madrid Auditorium (Abstract #LBA5).

The Opdivo plus Yervoy combination also improved OS in all randomized patients, a secondary endpoint. In this population, the combination reduced the risk of death 32% [HR 0.68; 99.8% CI: 0.49 to 0.95; P=0.0003] compared with sunitinib. The median OS had not yet been reached for the combination and was 32.9 months for sunitinib (95% CI: NA to NA).

Results for objective response rate (ORR) and progression-free survival (PFS) in intermediate- and poor-risk patients, the two other co-primary endpoints, were previously reported. The safety of the combination was consistent with that observed in previously reported studies of these medicines in patients with RCC.

“There is an unmet need for additional treatment options in the first line setting that may provide a meaningful survival benefit including more durable, complete responses for patients with advanced renal cell carcinoma. These results for the combination of nivolumab and ipilimumab are very encouraging in patients with first-line mRCC who have a very poor prognosis,” said Bernard Escudier, M.D., former chair of the genitourinary group of the Institut Gustave Roussy in Villejuif, France.

Adverse events (AEs) leading to discontinuation were reported in 22% of patients (547) in the combination group, compared with 12% of patients in the sunitinib group (535). The most common grade 3/4 AEs in the combination group were fatigue (4%), diarrhea (4%), rash (2%), nausea (2%), and, in less than 1% each, pruritus, hypothyroidism, vomiting and hypertension. In the sunitinib group, the most common grade 3/4 AEs were hypertension (16%), fatigue (9%), Palmar-plantar erythrodysaesthesia syndrome (9%), stomatitis (3%), mucosal inflammation (3%), vomiting (2%), nausea (1%), decreased appetite (1%), hypothyroidism (<1%) and dysgeusia (<1%). There were seven treatment-related deaths in the combination group and four in the sunitinib group.

“As the pioneer in Immuno-Oncology research, we set a goal of increasing overall survival for more patients by combining agents and have now, for the second time in a phase 3 trial, demonstrated that the Opdivo plus Yervoy combination may provide a survival advantage for patients,” said Vicki Goodman, M.D., head of new asset development, Bristol-Myers Squibb. “These positive data showing the Opdivo plus Yervoy combination improved survival in the first-line setting offer the potential, pending regulatory approval, to change the standard of care in the first-line treatment of advanced RCC and may represent a significant step forward for patients with this disease.”

About CheckMate -214

CheckMate -214 is a phase 3, randomized, open-label study evaluating the combination of Opdivo plus Yervoy versus sunitinib in patients with previously untreated advanced or metastatic renal cell carcinoma. Patients in the combination group received Opdivo 3 mg/kg plus Yervoy 1 mg/kg every 3 weeks for 4 doses followed by Opdivo 3 mg/kg every 2 weeks. Patients in the comparator group received sunitinib 50 mg once daily for 4 weeks, followed by 2 weeks off before continuation of treatment. Patients were treated until progression or unacceptable toxic effects. The primary endpoints of the trial are progression-free survival (PFS), overall survival (OS) and objective response rate (ORR) in an intermediate to poor-risk patient population (approximately 75% of patients). The majority of alpha was allocated to overall survival. Safety is a secondary endpoint.

The company previously reported that the combination of Opdivo plus Yervoy achieved an ORR of 42% versus 27% for sunitinib in poor- and intermediate-risk patients, a co-primary endpoint. Median duration of response was not reached for the combination and was 18.2 months for sunitinib. PFS in intermediate- and poor-risk patients, a co-primary endpoint, improved 18% for those receiving the combination (HR 0.82; 99.1% CI: 0.64 to 1.05; stratified two-sided p=0.0331) but did not reach the pre-defined statistical significance threshold of 0.009 compared with sunitinib. The median PFS for the combination group was 11.6 months (95% CI: 8.7 to 15.5) versus 8.4 months (95% CI: 7.0 to 10.8) for the sunitinib group.

About Renal Cell Carcinoma

Renal cell carcinoma (RCC) is the most common type of kidney cancer in adults, accounting for more than 100,000 deaths worldwide each year. Clear-cell RCC is the most prevalent type of RCC and constitutes 80% to 90% of all patients. RCC is approximately twice as common in men as in women, with the highest rates of the disease in North America and Europe. Globally, the five-year survival rate for those diagnosed with metastatic, or advanced, kidney cancer is 12.1%.

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.
