Patients treated with Opdivo experienced a 32% reduction in the risk of death after two years minimum follow-up

Opdivo remains the only PD-1 inhibitor to demonstrate statistically significant OS versus standard chemotherapy in the primary analysis of a Phase 3 trial in these patients, with benefit maintained with long-term follow-up

PRINCETON, NJ, USA I April 16, 2018 I Bristol-Myers Squibb Company (NYSE: BMY) announced today two-year overall survival (OS) data from CheckMate -141, a Phase 3 open-label, randomized trial evaluating Opdivo (nivolumab) compared with investigator’s choice chemotherapy (cetuximab, docetaxel or methotrexate) in patients with recurrent or metastatic squamous cell carcinoma of the head and neck (SCCHN) after failure on platinum-based therapy. Patients treated with Opdivo experienced a 32% reduction in the risk of death after a minimum two years of follow-up (HR 0.68; 95% CI: 0.54 to 0.86), with a median OS of 7.7 months (95% CI: 5.7 to 8.8) compared with 5.1 months (95% CI: 4.0 to 6.2) for standard chemotherapy. The two-year survival rate for Opdivo was 16.9% (95% CI: 12.4 to 22.0) versus 6.0% (95% CI: 2.7 to 11.3) for standard chemotherapy. The safety profile for Opdivo at two-year follow-up was consistent with previous analyses from the study.

These data will be presented today as an oral presentation (Abstract #CT116) at 4:35 PM CDT, N Hall C (Level 1) during the Updates in Immuno-Oncology Trials session at the 2018 American Association for Cancer Research (AACR) Annual Meeting in Chicago.

“The introduction of Immuno-Oncology has the potential to change the treatment landscape of squamous cell carcinoma of the head and neck, compared with the standard of care,” said Robert L. Ferris, M.D., Ph.D., a cancer immunotherapist and Director, UPMC Hillman Cancer Center, Pittsburgh, PA. “The sustained overall survival benefit demonstrated by nivolumab in this study is encouraging in SCCHN, which historically has a median survival of less than six months.”

The sustained Opdivo OS benefit was observed across PD-L1 expressors and non-expressors in patients with recurrent or metastatic SCCHN. At the two-year follow-up in patients treated with Opdivo whose tumors had PD-L1 expression ≥ 1%, risk of death was reduced by 45% (HR 0.55; 95% CI: 0.39 to 0.78). For patients treated with Opdivo whose tumors had PD-L1 expression <1%, risk of death at two years was reduced by 27% (HR 0.73; 95% CI: 0.49 to 1.09) versus standard chemotherapy.

Opdivo is the only I-O treatment for squamous cell carcinoma of the head and neck to have shown a significant overall survival benefit versus chemotherapy at the primary analysis. These two-year follow-up data show a sustained long-term overall survival benefit for patients, across PD-L1 expression levels and regardless of HPV status,” said Shinta Cheng, M.D., Ph.D., development lead, Bristol-Myers Squibb. “These data showing the durability of this benefit reinforce our ongoing commitment to continuing research with the hope of delivering what matters most to patients fighting cancer: long-term survival.”

There were no statistically significant differences between the two arms for PFS (HR 0.87; 95% CI: 0.68 to 1.11) for Opdivo and investigator’s choice, respectively. The safety profile of Opdivo with a two-year follow-up was consistent with previous analyses and with prior studies of Opdivo in patients with melanoma and non-small cell lung cancer. Grade 3-4 treatment-related adverse reactions occurred in 15.3% of patients receiving Opdivo versus 36.9% of patients receiving investigator’s choice.

About CheckMate -141 (Abstract #CT116)

CheckMate -141 is a global phase 3, open-label, randomized trial evaluating Opdivo versus investigator’s choice chemotherapy in patients with recurrent or metastatic SCCHN who had tumor progression during or within six months of receiving platinum-based therapy administered in the adjuvant, neo-adjuvant, primary (unresectable locally advanced) or metastatic setting. Patients were included regardless of their HPV or PD-L1 status. Patients were randomized 2:1 to receive Opdivo 3 mg/kg intravenously over 60 minutes every two weeks (n=240), or investigator’s choice (n=121) of methotrexate 40 to 60 mg/m2 intravenously weekly, docetaxel 30 to 40 mg/m2 intravenously weekly, or cetuximab 400 mg/m2 intravenously once then 250 mg/mweekly. The primary endpoint is OS. The trial’s secondary endpoints include progression-free survival (PFS) and objective response rate (ORR).

About Head & Neck Cancer

Cancers that are known as head and neck cancers usually begin in the squamous cells that line the moist mucosal surfaces inside the head and neck, such as inside the mouth, the nose and the throat. Head and neck cancer is the seventh most common cancer globally, with an estimated 400,000 to 600,000 new cases per year and 223,000 to 300,000 deaths per year. The five-year survival rate is reported as less than 4% for metastatic Stage IV disease. Squamous cell carcinoma of the head and neck (SCCHN) accounts for approximately 90% of all head and neck cancers, with global incidence expected to increase by 17% between 2012 and 2022. Risk factors for SCCHN include tobacco and alcohol consumption. The human papillomavirus (HPV) infection is also a risk factor leading to rapid increase in oropharyngeal SCCHN in Europe and North America. Quality of life is often impacted for SCCHN patients, as physiological function (breathing, swallowing, eating, drinking), personal characteristics (appearance, speaking, voice), sensory function (smell and hearing), and psychological/social function can be affected.

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 advancing 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 24 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. Through our leading translational capabilities, we are pioneering immune biology research and identifying a number of potentially predictive biomarkers, including PD-L1, TMB, MSI-H/dMMR and LAG-3, advancing the possibility of precision medicine for more patients with cancer.

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.
