PRINCETON, NJ, USA I January 19, 2017 I Bristol-Myers Squibb Company (NYSE:BMY) announced today the results of ONO-4538-12 demonstrating Opdivo (nivolumab) significantly reduced the risk of death by 37% (HR 0.63; p<0.0001) in patients with previously treated advanced gastric cancer refractory to or intolerant of standard therapy, a condition without current standard-of-care treatments. ONO-4538-12 is a Phase 3, randomized, double-blind, placebo-controlled clinical trial evaluating Opdivo’s efficacy and safety in such patients. The primary endpoint of the study is overall survival (OS). Median OS was 5.32 months (95% CI: 4.63 to 6.41) for patients treated with Opdivo, compared to 4.14 months (95% CI: 3.42 to 4.86) (p<0.0001) for those treated with placebo. In addition, the 12-month OS in the Opdivo group was 26.6% (95% CI: 21.1 to 32.4) versus 10.9% (95% CI: 6.2 to 17.0) in the placebo group. Patients treated with Opdivo also experienced an objective response rate of 11.2% (95% CI: 7.7 to 15.6) compared to 0% (95% CI: 0.0 to 2.8) with placebo and a median duration of response of 9.53 months (95% CI: 6.14 to 9.82), which were secondary endpoints.
The safety profile of Opdivo was consistent with previously reported studies in solid tumors. Treatment-related adverse events (TRAEs) of any grade and Grade 3/4 occurred in 42.7% versus 26.7% and 10.3% versus 4.3% of Opdivo-treated and placebo-treated patients, respectively. The Grade 3/4 TRAEs reported in more than 2% of patients were diarrhea, fatigue, decreased appetite, pyrexia, as well as increased AST and ALT in the Opdivo group, and fatigue and decreased appetite in the placebo group. The Opdivo and placebo-treated patients had similar rates of TRAEs leading to discontinuation, 2.7% and 2.5%, respectively.
The ONO-4538-12 data are being presented today in a late-breaking oral presentation from 2:00 – 3:30 p.m. PST (Abstract #2) at the 2017 Gastrointestinal Cancers Symposium in San Francisco, Calif.
“ONO-4538-12 is the first randomized, Phase 3 Immuno-Oncology trial to demonstrate improved survival for patients with previously treated advanced or recurrent gastric cancer. We find these results with Opdivo encouraging, as gastric cancer is a leading cause of cancer death globally and unmet needs remain for patients with advanced forms of this disease who become intolerant to chemotherapy or for whom such treatment has failed,” said Ian M. Waxman, M.D., development lead, Gastrointestinal Oncology, Bristol-Myers Squibb.
“These results show a clinical benefit with Opdivo for patients with pretreated advanced or recurrent gastric cancer and establish a strong basis for conducting additional studies with Opdivo as a treatment for patients with gastric cancer,” added lead study investigator Yoon-Koo Kang, M.D., Ph.D., of the Department of Oncology at the University of Ulsan College of Medicine, Asan Medical Center in Seoul, Korea.
ONO-4538-12 (NCT02267343) is a Phase 3, randomized, double-blind, placebo-controlled clinical trial conducted in Japan, Korea and Taiwan, evaluating the efficacy and safety of Opdivo in patients with unresectable (unable to be removed with surgery) previously treated advanced or recurrent gastric cancer, including gastroesophageal junction cancer, refractory to or intolerant of standard therapy. This trial was conducted by Ono Pharmaceutical Co. Ltd. of Japan, Bristol-Myers Squibb’s development partner for Opdivo.
In ONO-4538-12, Opdivo 3 mg/kg or placebo was administered every two weeks until disease progression or discontinuation due to unacceptable toxicity. The primary endpoint, OS, was assessed for the superiority of Opdivo versus placebo. The secondary endpoints included objective response rate, duration of response, progression free survival, best overall response, time to response, disease control rate and safety measures.
About Gastric Cancer
Gastric cancer, also known as stomach cancer, is the fifth most common malignancy in the world, with more than 950,000 patients diagnosed each year, and is the third leading cause of cancer-related death, with more than 720,000 deaths reported annually. The prevalence of gastric cancer is higher in East Asian countries than in Western countries. While the five-year survival rate for people with gastric cancer is 30.4%, this rate falls to approximately 5% for those whose gastric cancer has metastasized (or spread). Because no standard-of-care treatment options exist for patients with unresectable advanced or recurrent gastric cancer after chemotherapy, there remains an important unmet medical need for patients with this condition.
Bristol-Myers Squibb: At the Forefront of Immuno-Oncology Science & Innovation
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 that will raise survival expectations in hard-to-treat cancers and will change the way patients live with cancer.
We are leading the scientific understanding of I-O through our extensive portfolio of investigational and approved agents, including the first combination of two I-O agents in metastatic melanoma, and our differentiated clinical development program, which is studying broad patient populations across more than 20 types of cancers with 11 clinical-stage molecules designed to target different immune system pathways. Our deep expertise and innovative clinical trial designs uniquely position us to advance the science of combinations across multiple tumors and potentially deliver the next wave of I-O combination regimens 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 inform which patients will benefit most from I-O therapies.
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.
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.

About the Bristol-Myers Squibb and Ono Pharmaceutical Collaboration
In 2011, through a collaboration agreement with Ono Pharmaceutical Co., Bristol-Myers Squibb expanded its territorial rights to develop and commercialize Opdivo globally except in Japan, South Korea and Taiwan, where Ono had retained all rights to the compound at the time. On July 2014, Ono and Bristol-Myers Squibb further expanded the companies’ strategic collaboration agreement to jointly develop and commercialize multiple immunotherapies – as single agents and combination regimens – for patients with cancer in Japan, South Korea and Taiwan.
