Opdivo (nivolumab) Plus Chemotherapy Demonstrated Significant Overall and Progression-Free Survival Benefits Versus Chemotherapy in First-Line Treatment of Gastric and Esophageal Cancers
September 21, 2020Overall survival and progression-free survival benefit observed in patients whose tumors express PD-L1; overall survival benefit also observed in all-randomized population
Efficacy benefit observed across patients with gastric cancer, gastroesophageal junction cancer or esophageal adenocarcinoma
Primary results from Phase 3 CheckMate -649 trial featured in official Press Programme and selected for presentation during a Presidential Symposium at the European Society for Medical Oncology Virtual Congress 2020
PRINCETON, N.J.–(BUSINESS WIRE)–$BMY #BMS—Bristol Myers Squibb (NYSE: BMY) today announced primary results from CheckMate -649, the pivotal Phase 3 trial in which first-line treatment with Opdivo (nivolumab) plus chemotherapy showed a statistically significant and clinically meaningful improvement in the overall survival (OS) and progression-free survival (PFS) of patients with unresectable advanced or metastatic gastric cancer, gastroesophageal junction (GEJ) cancer or esophageal adenocarcinoma compared to treatment with chemotherapy alone. Opdivo is the first PD-1 inhibitor to demonstrate superior OS and PFS in combination with chemotherapy when compared to chemotherapy alone in patients with gastric cancer, GEJ cancer or esophageal adenocarcinoma. The OS and PFS benefits were observed in patients whose tumors express PD-L1 with a combined positive score (CPS) ≥ 5, achieving both of the trial’s primary endpoints. The OS benefit was also observed in the all-randomized trial population.
Median OS (Hazard Ratio [HR]: 0.71; 98.4% Confidence Interval [CI]: 0.59 to 0.86; p<0.0001) for Opdivo plus chemotherapy was 14.4 months (95% CI: 13.1 to 16.2) compared to 11.1 months (95% CI: 10. (Read more…)0 to 12.1) for chemotherapy alone among PD-L1 positive patients with CPS ≥ 5. The median PFS (HR: 0.68; 98% CI: 0.56 to 0.81; p<0.0001) was 7.7 months (95% CI: 7.0 to 9.2) in those treated with Opdivo plus chemotherapy and 6.0 months (95% CI: 5.6 to 6.9) among those treated with chemotherapy alone. The safety profiles of Opdivo and chemotherapy in this trial were reflective of the known safety profiles of Opdivo and chemotherapy with no new safety signals observed.
CheckMate -649 is the largest randomized, global Phase 3 study of an immune checkpoint inhibitor-based therapy in the first-line setting for patients with gastric and esophageal cancers conducted to date.
“Currently, the first-line standard of care for patients with advanced or metastatic non-HER2 positive gastric or gastroesophageal junction cancer is chemotherapy. While it has been an important treatment option for these patients, chemotherapy alone is associated with a marginal survival benefit of often less than one year from the time a patient’s treatment is initiated,” said Markus Moehler, M.D., Professor of Gastrointestinal Oncology, Johannes-Gutenberg University Medical Center, Mainz. “Innovative treatments are urgently needed for patients around the world who are living with these advanced or metastatic upper gastrointestinal cancers, as there are currently no approved immunotherapy options in the first-line setting.”
The statistically significant OS benefit shown with Opdivo plus chemotherapy was also observed in PD-L1 positive patients with CPS ≥ 1 and in the all-randomized population. In the all-randomized population, the median OS was 13.8 months (95% CI: 12.6 to 14.6) for patients receiving Opdivo plus chemotherapy compared to 11.6 months (95% CI: 10.9 to 12.5) for patients receiving chemotherapy alone (HR: 0.80; 99.3% CI: 0.68 to 0.94; p=0.0002). In PD-L1 positive patients with CPS ≥ 1, median OS was 14.0 months (95% CI: 12.6 to 15.0) for patients receiving Opdivo plus chemotherapy compared to 11.3 months (95% CI: 10.6 to 12.3) for patients receiving chemotherapy alone (HR: 0.77; 99.3% CI: 0.64 to 0.92; p=0.0001).
“CheckMate -649 recently became the first global study in over a decade to demonstrate a significant overall survival benefit over chemotherapy in the first-line setting of non-HER2 positive gastric cancer, gastroesophageal junction cancer or esophageal adenocarcinoma, highlighting the potential of Opdivo plus chemotherapy to become a new standard of care for these patients, regardless of their tumor location,” said Ian M. Waxman, M.D., development lead, Gastrointestinal Cancers, Bristol Myers Squibb. “These available results of the CheckMate -649 study will be discussed with global health authorities as we strive to bring this important new treatment option to patients in need.”
The incidence of serious treatment-related adverse events (TRAEs), any grade and Grade 3-4, was modestly higher among patients treated with Opdivo plus chemotherapy (any grade 22%, Grade 3-4 17%) compared to patients treated with chemotherapy alone (any grade 12%, Grade 3-4 10%). Of patients treated with Opdivo plus chemotherapy, 36% and 17% experienced TRAEs of any grade or Grade 3-4 leading to discontinuation, compared to 24% and 9% of patients treated with chemotherapy. The incidence of TRAEs in patients treated with Opdivo plus chemotherapy was consistent across patient sub-groups.
These data (Presentation #LBA6_PR) will be featured in a Presidential Symposium at the European Society for Medical Oncology (ESMO) Virtual Congress 2020 on September 21 from 18:30-18:42 CEST.
About CheckMate -649
Checkmate -649 is a Phase 3 randomized, multi-center, open-label study evaluating Opdivo plus chemotherapy or the Opdivo plus Yervoy (ipilimumab) combination compared to chemotherapy alone in patients with previously untreated, non-HER2-positive, advanced or metastatic gastric cancer, GEJ cancer or esophageal adenocarcinoma. The primary endpoints of the trial are OS in PD-L1 positive patients with a combined positive score (CPS) ≥ 5 treated with Opdivo plus chemotherapy and PFS, as assessed by Blinded Independent Central Review (BICR), in CPS ≥ 5 patients treated with Opdivo plus chemotherapy compared to chemotherapy alone. Key secondary endpoints include OS in CPS ≥ 1 and all-randomized patients treated with Opdivo plus chemotherapy as well as OS and time to symptom deterioration (TTSD) in patients treated with Opdivo plus Yervoy compared to chemotherapy alone.
Patients in the Opdivo plus chemotherapy arm received Opdivo 360 mg plus capecitabine and oxaliplatin (CapeOX) every three weeks or Opdivo 240 mg plus 5-fluorouracil, leucovorin and oxaliplatin (FOLFOX) every two weeks. Patients in the Opdivo plus Yervoy arm received Opdivo 1 mg/kg plus Yervoy 3 mg/kg every three weeks for four cycles followed by Opdivo 240 mg every two weeks. Patients in the chemotherapy arm received FOLFOX or CapeOX every two or three weeks, respectively. All patients continued treatment for two years or until disease progression, unacceptable toxicity or withdrawal of consent.
About Gastric Cancer
Gastric cancer, also known as stomach cancer, is the fifth most common cancer and the third leading cause of cancer death worldwide, with over 1,000,000 new cases and approximately 783,000 deaths in 2018. There are several cancers that can be classified as gastric cancer, including certain types of cancers that form in the GEJ, the area of the digestive tract where the esophagus and stomach connect. While GEJ cancer has a lower prevalence than gastric cancer, it continues to rise. First-line treatment for patients with gastric or GEJ cancer often provides the best chance for efficacy as many patients cannot proceed to subsequent treatments in later settings due to deterioration.
About Esophageal Cancer
Esophageal cancer is the seventh most common cancer and the sixth leading cause of death from cancer worldwide, with approximately 572,000 new cases and over 508,000 deaths in 2018. The two most common types of esophageal cancer are squamous cell carcinoma and adenocarcinoma, which account for approximately 85% and 15% of all esophageal cancers, respectively, though esophageal tumor histology can vary by region with the highest rate of esophageal adenocarcinoma occurring in North America (65%). The majority of cases are diagnosed in the advanced setting and impact a patient’s daily life, including their ability to eat and drink.
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.

IMPORTANT SAFETY INFORMATION
Severe and Fatal Immune-Mediated Adverse Reactions
Immune-mediated adverse reactions listed herein may not be inclusive of all possible severe and fatal immune-mediated adverse reactions.
Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue. While immune-mediated adverse reactions usually manifest during treatment, they can also occur at any time after starting or discontinuing YERVOY. Early identification and management are essential to ensure safe use of YERVOY. Monitor for signs and symptoms that may be clinical manifestations of underlying immune-mediated adverse reactions. Evaluate clinical chemistries including liver enzymes, creatinine, adrenocorticotropic hormone (ACTH) level, and thyroid function at baseline and before each dose. Institute medical management promptly, including specialty consultation as appropriate.
Withhold or permanently discontinue YERVOY depending on severity. In general, if YERVOY requires interruption or discontinuation, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less followed by corticosteroid taper for at least 1 month. Consider administration of other systemic immunosuppressants in patients whose immune-mediated adverse reaction is not controlled with corticosteroid therapy. Institute hormone replacement therapy for endocrinopathies as warranted.
Immune-Mediated Pneumonitis
OPDIVO can cause immune-mediated pneumonitis. Fatal cases have been reported. Monitor patients for signs with radiographic imaging and for symptoms of pneumonitis. Administer corticosteroids for Grade 2 or more severe pneumonitis. Permanently discontinue for Grade 3 or 4 and withhold until resolution for Grade 2. In patients receiving OPDIVO monotherapy, fatal cases of immune-mediated pneumonitis have occurred. Immune-mediated pneumonitis occurred in 3.1% (61/1994) of patients. In melanoma patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg, immune-mediated pneumonitis occurred in 6% (25/407) of patients. In HCC patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg, immune-mediated pneumonitis occurred in 10% (5/49) of patients. In RCC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg, immune-mediated pneumonitis occurred in 4.4% (24/547) of patients. In MSI-H/dMMR mCRC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg, immune-mediated pneumonitis occurred in 1.7% (2/119) of patients. In NSCLC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg, immune-mediated pneumonitis occurred in 9% (50/576) of patients, including Grade 4 (0.5%), Grade 3 (3.5%), and Grade 2 (4.0%) immune-mediated pneumonitis. Four patients (0.7%) died due to pneumonitis. The incidence and severity of immune-mediated pneumonitis in patients with NSCLC treated with OPDIVO 360 mg every 3 weeks in combination with YERVOY 1 mg/kg every 6 weeks and 2 cycles of platinum-doublet chemotherapy were comparable to treatment with OPDIVO in combination with YERVOY only.
In Checkmate 205 and 039, pneumonitis, including interstitial lung disease, occurred in 6.0% (16/266) of patients receiving OPDIVO. Immune-mediated pneumonitis occurred in 4.9% (13/266) of patients receiving OPDIVO: Grade 3 (n=1) and Grade 2 (n=12).
Immune-Mediated Colitis
OPDIVO can cause immune-mediated colitis. Monitor patients for signs and symptoms of colitis. Administer corticosteroids for Grade 2 (of more than 5 days duration), 3, or 4 colitis. Withhold OPDIVO monotherapy for Grade 2 or 3 and permanently discontinue for Grade 4 or recurrent colitis upon re-initiation of OPDIVO. When administered with YERVOY, withhold OPDIVO and YERVOY for Grade 2 and permanently discontinue for Grade 3 or 4 or recurrent colitis. In patients receiving OPDIVO monotherapy, immune-mediated colitis occurred in 2.9% (58/1994) of patients. In melanoma patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg, immune-mediated colitis occurred in 26% (107/407) of patients including three fatal cases. In HCC patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg, immune-mediated colitis occurred in 10% (5/49) of patients. In RCC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg, immune-mediated colitis occurred in 10% (52/547) of patients. In MSI-H/dMMR mCRC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg, immune-mediated colitis occurred in 7% (8/119) of patients.
In a separate Phase 3 trial of YERVOY 3 mg/kg, immune-mediated diarrhea/colitis occurred in 12% (62/511) of patients, including Grade 3-5 (7%).
Cytomegalovirus (CMV) infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies. Addition of an alternative immunosuppressive agent to the corticosteroid therapy, or replacement of the corticosteroid therapy, should be considered in corticosteroid-refractory immune-mediated colitis if other causes are excluded.
Immune-Mediated Hepatitis
OPDIVO can cause immune-mediated hepatitis. Monitor patients for abnormal liver tests prior to and periodically during treatment. Administer corticosteroids for Grade 2 or greater transaminase elevations. For patients without HCC, withhold OPDIVO for Grade 2 and permanently discontinue OPDIVO for Grade 3 or 4. For patients with HCC, withhold OPDIVO and administer corticosteroids if AST/ALT is within normal limits at baseline and increases to >3 and up to 5 times the upper limit of normal (ULN), if AST/ALT is >1 and up to 3 times ULN at baseline and increases to >5 and up to 10 times the ULN, and if AST/ALT is >3 and up to 5 times ULN at baseline and increases to >8 and up to 10 times the ULN. Permanently discontinue OPDIVO and administer corticosteroids if AST or ALT increases to >10 times the ULN or total bilirubin increases >3 times the ULN. In patients receiving OPDIVO monotherapy, immune-mediated hepatitis occurred in 1.8% (35/1994) of patients. In melanoma patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg, immune-mediated hepatitis occurred in 13% (51/407) of patients.
