ONO PHARMACEUTICAL : U.S. Food and Drug Administration Accepts for Priority Review Bristol-Myers Squibb’s Application for Opdivo (nivolumab) in Previously Treated dMMR or MSI-H Metastatic Colorectal Cancer (151KB)

April 6, 2017

(PRINCETON, N.J., April 4, 2017) - Bristol-Myers Squibb Company (NYSE: BMY) announced that the U.S. Food and Drug Administration (FDA) accepted a supplemental Biologics License Application (sBLA) that seeks to extend the use of Opdivo (nivolumab) to patients with mismatch repair deficient (dMMR) or microsatellite instability high (MSI-H) metastatic colorectal cancer (CRC) after prior fluoropyrimidine-, oxaliplatin- and irinotecan-based chemotherapy. The FDA granted the application priority review, and the FDA action date is August 2, 2017.

Bristol-Myers Squibb (BMS) has a robust clinical development program in Opdivo monotherapy and in combination therapy with other therapeutic drugs in a variety of tumor types overseas, including glioblastoma, small cell lung cancer, urothelial cancer, hepatocellular carcinoma, esophageal cancer, colorectal cancer, gastric cancer, blood cancer, etc.

In Japan, Ono Pharmaceutical Co., Ltd. (ONO) launched Opdivo for the treatment of unresectable melanoma in September 2014. ONO received an approval for additional indication of unresectable, advanced or recurrent non-small cell lung cancer in December 2015 and unresectable or metastatic renal cell cancer in August 2016, relapsed or refractory classical Hodgkin lymphoma in December 2016 and recurrent or metastatic head and neck cancer on March 24, 2017. In addition, ONO has submitted supplemental application for additional indication of gastric cancer, and is conducting clinical development program including esophageal cancer, gastro-esophageal junction cancer, small cell lung cancer, hepatocellular carcinoma, glioblastoma, urothelial cancer, malignant pleural mesothelioma, ovarian cancer, biliary tract cancer, etc.

In Japan, ONO and BMS (and BMS Japan subsidiary BMSKK) have formed a strategic partnership that includes co-development, co-commercialization, and co-promotion of multiple immunotherapies for patients with cancer.

Application based on results from Phase 2 CheckMate -142 study

(PRINCETON, N.J., April 4, 2017) - Bristol-Myers Squibb Company (NYSE: BMY) today announced that the U.S. Food and Drug Administration (FDA) accepted a supplemental Biologics License Application (sBLA) that seeks to extend the use of Opdivo (nivolumab) to patients with mismatch repair deficient (dMMR) or microsatellite instability high (MSI-H) metastatic colorectal cancer (CRC) after prior fluoropyrimidine-, oxaliplatin- and irinotecan- based chemotherapy. The FDA granted the application priority review, and the FDA action date is August 2, 2017.

"We look forward to working with the FDA towards the goal of providing a new treatment option for patients with metastatic colorectal cancer defined by dMMR or MSI-H biomarkers. These patients have a distinct unmet need, as they are less likely to benefit from conventional chemotherapy and have a shorter overall survival than patients with metastatic colorectal cancer without these biomarkers," said Ian M. Waxman, M.D., development lead, Gastrointestinal Oncology, Bristol-Myers Squibb. "This milestone illustrates Bristol-Myers Squibb's continued efforts to evaluate the potential of Immuno-Oncology in a broad range of cancers and represents an important advancement in our approach to translational medicine."

The submission was based on data from the ongoing Phase 2 CheckMate -142 trial evaluating Opdivo in patients with dMMR or MSI-H metastatic CRC. The efficacy endpoints include investigator-assessed and blinded independent central review committee-assessed objective response rate (ORR) based on the Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1, duration of response, progression-free survival and overall survival.

Data from this study were presented at the 2017 Gastrointestinal Cancers Symposium in January.

About Colorectal Cancer and dMMR or MSI-H Colorectal Cancer

Colorectal cancer (CRC) is cancer that develops in the colon or the rectum, which are part of the body's digestive or gastrointestinal system. In the United States, CRC is the third most common cancer and the second leading cause of cancer-related

deaths among men and women combined, with more than 134,000 new cases expected to be diagnosed annually.

Mismatch repair deficiency (dMMR) occurs when the proteins that repair mismatch errors in DNA replication are missing or non-functional, which leads to microsatellite instability-high (MSI-H) tumors in certain types of cancer, including CRC. Approximately 15% of CRC patients and 4-5% of metastatic CRC patients have dMMR or MSI-H biomarkers. Patients with dMMR or MSI-H metastatic CRC are less likely to benefit from conventional chemotherapy and typically have a poor prognosis, with lower survival rates on conventional chemotherapy than patients whose tumors are mismatch repair proficient. Routine testing to confirm dMMR or MSI-H status should be conducted for all CRC patients.

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 35 types of cancers with 13 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.

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.
