Opdivo (nivolumab) Plus Yervoy (ipilimumab) with Limited Chemotherapy Significantly Improves Overall Survival vs. Chemotherapy Alone for Patients with First-Line Metastatic Non-Small Cell Lung Cancer in CheckMate -9LA Study

Opdivo plus Yervoy given concomitantly with two cycles of chemotherapy demonstrated prolonged overall survival at an interim analysis, with sustained improvement in a subsequent analysis with a minimum follow-up of one year

Clinical benefit was consistent across all efficacy measures, regardless of PD-L1 expression or tumor histology

First results from CheckMate -9LA to be presented in an oral session during ASCO 2020

PRINCETON, NJ, USA I May 13, 2020 IBristol Myers Squibb (NYSE: BMY) today announced the first presentation of results from the Phase 3 CheckMate -9LA trial, which demonstrated a statistically significant and clinically meaningful survival benefit with Opdivo (nivolumab) plus Yervoy (ipilimumab), given concomitantly with two cycles of chemotherapy, for the first-line treatment of metastatic non-small cell lung cancer (NSCLC). The study met both its primary and key secondary endpoints, demonstrating superior overall survival (OS), progression-free survival (PFS) and overall response rate (ORR) for the dual immunotherapy plus chemotherapy combination versus chemotherapy alone.

At a prespecified interim analysis for the primary endpoint of OS, Opdivo plus Yervoy combined with two cycles of chemotherapy reduced the risk of death by 31% compared to chemotherapy alone at a minimum follow-up of 8.1 months [Hazard Ratio (HR): 0.69, 96.71% Confidence Interval (CI): 0.55 to 0.87; p=0.0006]. Additionally, with longer follow-up (minimum of 12.7 months), the combination continued to show sustained OS improvements over chemotherapy alone (median OS of 15.6 months versus 10.9 months, respectively [HR: 0.66, 95% CI: 0.55 to 0.80]). The clinical benefit was observed across all efficacy measures in key population subgroups, including by PD-L1 expression and tumor histology (squamous or non-squamous).

The safety profile of Opdivo (360 mg every three weeks) plus Yervoy (1 mg/kg every six weeks) and two cycles of chemotherapy was reflective of the known safety profiles of the immunotherapy and chemotherapy components in first-line NSCLC. These results (Abstract #9501) will be featured in an oral session at the American Society of Clinical Oncology (ASCO) Annual Meeting 2020, held virtually, from May 29-31.

“The nivolumab plus ipilimumab combination has been shown to increase survival in patients with first-line non-small cell lung cancer, and adding a limited course of chemotherapy may help mitigate the risk of early disease progression,” said Martin Reck, M.D., Ph.D., CheckMate -9LA study investigator, Lung Clinic Grosshansdorf, German Center of Lung Research. “With these results from CheckMate -9LA, we now have evidence that this dual immunotherapy combination, when administered concomitantly with two cycles of chemotherapy, provides a survival benefit in this setting – a benefit that was observed early and sustained at one year of follow-up across key subgroups of patients. As the data become more mature, I see the potential for an improving survival benefit over time.”

With a minimum follow-up of 12.7 months, Opdivo plus Yervoy with limited chemotherapy improved OS regardless of PD-L1 expression levels, reducing the risk of death by 38% in patients with PD-L1 <1% (HR: 0.62, 95% CI: 0.45 to 0.85) and by 36% in patients with PD-L1 ≥ 1% (HR: 0.64, 95% CI: 0.50 to 0.82). In addition, the dual immunotherapy and chemotherapy combination demonstrated a one-year PFS rate of 33% versus 18% for chemotherapy (HR: 0.68, 95% CI: 0.57 to 0.82), and an ORR of 38% compared to 25% with chemotherapy alone.

“Understanding that each patient facing a diagnosis of metastatic non-small lung cancer is unique, we’ve approached our development program with the goal of delivering a number of potentially durable solutions for the significant number of first-line patients who still need new options,” said Nick Botwood, M.D., vice president, Oncology Clinical Development, Bristol Myers Squibb. “The updated one-year overall survival data from CheckMate -9LA, along with three-year results from our CheckMate -227 trial, further reinforce the clinical value of Opdivo plus Yervoy-based combinations, the first-ever dual immunotherapy options for the treatment of first-line non-small cell lung cancer.”

Opdivo plus Yervoy is a unique combination of two immune checkpoint inhibitors that features a potentially synergistic mechanism of action, targeting two different checkpoints (PD-1 and CTLA-4) to help destroy tumor cells: Yervoy helps activate and proliferate T cells, while Opdivo helps existing T cells discover the tumor. Some of the T cells stimulated by Yervoy can become memory T cells, which may allow for a long-term immune response. The addition of limited chemotherapy to the Opdivo plus Yervoy combination may help patients achieve early disease control.

About CheckMate -9LA

CheckMate -9LA is an open-label, multi-center, randomized Phase 3 trial evaluating Opdivo (360 mg Q3W) plus Yervoy (1 mg/kg Q6W) combined with chemotherapy (two cycles) compared to chemotherapy alone (up to four cycles followed by optional pemetrexed maintenance therapy if eligible) as a first-line treatment in patients with metastatic non-small cell lung cancer (NSCLC) regardless of PD-L1 expression and histology. Patients in the experimental arm were treated with immunotherapy for up to two years or until disease progression or unacceptable toxicity. Patients in the control arm were treated with up to four cycles of chemotherapy and optional pemetrexed maintenance (if eligible) until disease progression or unacceptable toxicity. The primary endpoint of the trial was overall survival (OS) in the intent-to-treat (ITT) population. Secondary hierarchical endpoints included progression-free survival (PFS) and overall response rate (ORR), and the study also evaluated efficacy measures according to biomarkers.

About Lung Cancer

Lung cancer is the leading cause of cancer deaths globally. The two main types of lung cancer are non-small cell and small cell. Non-small cell lung cancer (NSCLC) is one of the most common types of lung cancer and accounts for up to 84% of diagnoses. Survival rates vary depending on the stage and type of the cancer when diagnosed. For patients diagnosed with metastatic lung cancer, the five-year survival rate is approximately 5%.

Bristol Myers Squibb: Advancing Cancer Research

At Bristol Myers Squibb, patients are at the center of everything we do. The goal of our cancer research is to increase patients’ quality of life, long-term survival and make cure a possibility. We harness our deep scientific experience, cutting-edge technologies and discovery platforms to discover, develop and deliver novel treatments for patients.

Building upon our transformative work and legacy in hematology and Immuno-Oncology that has changed survival expectations for many cancers, our researchers are advancing a deep and diverse pipeline across multiple modalities. In the field of immune cell therapy, this includes registrational CAR T cell agents for numerous diseases, and a growing early-stage pipeline that expands cell and gene therapy targets, and technologies. We are developing cancer treatments directed at key biological pathways using our protein homeostasis platform, a research capability that has been the basis of our approved therapies for multiple myeloma and several promising compounds in early- to mid-stage development. Our scientists are targeting different immune system pathways to address interactions between tumors, the microenvironment and the immune system to further expand upon the progress we have made and help more patients respond to treatment. Combining these approaches is key to delivering potential new options for the treatment of cancer and addressing the growing issue of resistance to immunotherapy. We source innovation internally, and in collaboration with academia, government, advocacy groups and biotechnology companies, to help make the promise of transformational medicines 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.

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.
