Data to be presented at the European Society for Medical Oncology Virtual Congress 2021

PRINCETON, NJ, USA I September 16, 2021 I Bristol Myers Squibb (NYSE: BMY) today announced that Opdivo (nivolumab) plus Yervoy (ipilimumab) continued to demonstrate durable, long-term survival in the Phase 3 CheckMate -214 trial, with a five-year survival rate of 48% in patients with previously untreated advanced or metastatic renal cell carcinoma (RCC). After a median follow-up of 67.7 months, Opdivo plus Yervoy maintained superior overall survival (OS) and response benefits versus sunitinib in both patients with intermediate- and poor-risk prognostic factors, the primary endpoint population, and across all randomized patients.

In intermediate- and poor-risk patients (n=847), Opdivo plus Yervoy (n=425) maintained treatment effects over five years, with ongoing improvements in OS and overall response rate (ORR), two of the trial’s primary endpoints, as well as in supportive endpoints:

  • OS: The median OS was 47.0 months for intermediate- and poor-risk patients treated with Opdivo plus Yervoy versus 26.6 months with sunitinib (Hazard Ratio [HR] 0.68; 95% Confidence Interval [CI]: 0.58 to 0.81), and five-year survival rates were 43% and 31%, respectively.
  • ORR: ORR benefits were maintained with Opdivo plus Yervoy compared to sunitinib (42% vs. 27%). In addition, more patients treated with the combinationachieved complete responses (11% vs. 2%).
  • Duration of response (DOR): For patients treated with Opdivo plus Yervoy, median DOR was not reached, compared to 19.7 months with sunitinib.

An analysis of all randomized patients, or the intent-to-treat (ITT) population (n=1,096), similarly showed long-term benefits with Opdivo plus Yervoy (n=550):

  • OS: Opdivo plus Yervoy demonstrated a median OS of 55.7 months in the ITT population, representing the longest survival outcome reported to date in a Phase 3 trial in advanced RCC, compared to 38.4 months with sunitinib (HR 0.72; 95% CI: 0.62 to 0.85). Five-year OS rates were 48% for patients treated with the dual immunotherapy combination and 37% for those receiving sunitinib.
  • ORR: Opdivo plus Yervoy continued to show a higher ORR (39% vs. 32%) and complete response rate than sunitinib (12% vs. 3%). Also, more patients treated with the combinationachieved complete responses and subsequently did not progress (9.6% vs. 2.4%).
  • DOR: Median DOR was not reached with Opdivo plus Yervoy and was 24.8 months with sunitinib.

The safety profile of Opdivo plus Yervoy was manageable using established treatment algorithms, and no new safety signals emerged with extended follow-up. These data were published online during the European Society for Medical Oncology (ESMO) Virtual Congress 2021 on September 16, 2021, 08:30 CEST (Abstract #661P).

“The five-year data from the CheckMate -214 trial demonstrate that nearly half of patients lived longer after five years in this Phase 3 trial for advanced renal cell carcinoma,” said Robert J. Motzer, M.D., CheckMate -214 investigator and Kidney Cancer Section Head, Genitourinary Oncology Service, Jack and Dorothy Byrne Chair in Clinical Oncology, Memorial Sloan Kettering Cancer Center. “While the median duration of response has not yet been reached with nivolumab plus ipilimumab, the data show some durable effects of this combination for patients living with this disease.”

“Four years ago, we presented the first results from CheckMate -214 during ESMO, which helped to transform the standard of care in advanced renal cell carcinoma. Now, with the longest follow-up for any Phase 3 trial of an immunotherapy combination in this disease, we’re seeing truly long-term survival benefits with Opdivo plus Yervoy,” said Dana Walker, M.D., M.S.C.E., vice president, development program lead, genitourinary cancers, Bristol Myers Squibb. “These five-year results in renal cell carcinoma add to the evidence we have seen in several other tumor types of the unique role that Opdivo plus Yervoy-based combinations can play in changing survival outcomes for patients with cancer.”

The five-year data from CheckMate -214 presented during ESMO also included conditional survival analyses, which estimate the probability of remaining event-free (i.e., remaining alive, progression-free or in response) for a period of time after a patient reaches a milestone in their treatment. Key findings included:

  • Patients who were alive three years after starting treatment with Opdivo plus Yervoy had an 81% probability of remaining alive for an additional two years, compared to 72% with sunitinib.
  • Patients who were progression-free three years after starting treatment with the dual immunotherapy combination had an 89% probability of remaining progression-free for an additional two years, compared to 57% with sunitinib.
  • Patients who responded to treatment with the combination and remained in response for three years had an 89% probability of remaining in response for two additional years vs. 63% with sunitinib.

Bristol Myers Squibb thanks the patients and investigators involved in the CheckMate -214 clinical trial.

Opdivo plus Yervoy-based combinations have shown significant improvements in OS in six Phase 3 clinical trials in five tumors to date: advanced renal cell carcinoma, non-small cell lung cancer, metastatic melanoma, malignant pleural mesothelioma and esophageal squamous cell carcinoma.

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 (RCC). Patients in the combination group (n=550) received Opdivo 3 mg/kg plus Yervoy 1 mg/kg every three weeks for four doses followed by Opdivo 3 mg/kg every two weeks. Patients in the comparator group (n=546) received sunitinib 50 mg once daily for four weeks, followed by two weeks off before continuation of treatment. Patients were treated until progression or unacceptable toxic effects for up to two years. The primary endpoints of the trial are overall survival (OS), progression-free survival (PFS) and objective response rate (ORR) in an intermediate- to poor-risk patient population (approximately 75% of patients). ORR was assessed by independent radiology review committee (IRRC).

About Renal Cell Carcinoma

Renal cell carcinoma (RCC) is the most common type of kidney cancer in adults, accounting for more than 431,000 new cases and 179,000 deaths worldwide each year. RCC is approximately twice as common in men as in women, with the highest rates of the disease in North America and Europe. Historically, the five-year survival rate for those diagnosed with metastatic, or advanced, kidney cancer is 13%.

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 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.

About Yervoy

Yervoy is a recombinant, human monoclonal antibody that binds to the cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4). CTLA-4 is a negative regulator of T-cell activity. Yervoy binds to CTLA-4 and blocks the interaction of CTLA-4 with its ligands, CD80/CD86. Blockade of CTLA-4 has been shown to augment T-cell activation and proliferation, including the activation and proliferation of tumor infiltrating T-effector cells. Inhibition of CTLA-4 signaling can also reduce T-regulatory cell function, which may contribute to a general increase in T-cell responsiveness, including the anti-tumor immune response. On March 25, 2011, the U.S. Food and Drug Administration (FDA) approved Yervoy 3 mg/kg monotherapy for patients with unresectable or metastatic melanoma. Yervoy is approved for unresectable or metastatic melanoma in more than 50 countries. There is a broad, ongoing development program in place for Yervoy spanning multiple tumor types.
