PRINCETON, N.J.--(BUSINESS WIRE)--?Bristol Myers Squibb?(NYSE: BMY) today announced three-year data from the CheckMate -743 trial that demonstrated a durable survival benefit with first-line treatment with?Opdivo?(nivolumab) plus?Yervoy?(ipilimumab) compared to platinum-based standard-of-care chemotherapy in patients with unresectable malignant pleural mesothelioma (MPM), regardless of histology. With a minimum follow-up of three years (35.5 months):

• Among patients treated with?Opdivo?plus?Yervoy, 23% were alive at three years, compared to 15% of patients treated with chemotherapy.
• Treatment with the dual immunotherapy combination continued to show a reduction in the risk of death (Hazard Ratio [HR] 0.73; 95% Confidence Interval [CI]: 0.61 to 0.87), and improvement in median overall survival (OS), the trial?s primary endpoint, vs. chemotherapy (18.1 months vs. 14.1 months, respectively).

The safety profile for?Opdivo?plus?Yervoy?remained consistent with previously reported data in first-line MPM, with no new safety signals identified. These data will be presented on September 17, 2021 at 13:40 CEST/7:40 a.m. EDT (Abstract #LBA65) during the Proffered Paper session at the 2021 European Society for Medical Oncology (ESMO) Virtual Congress. ?For patients with malignant pleural mesothelioma, the prognosis is generally poor, with a five-year survival rate of approximately 10%,? said Solange Peters, M.D., Ph.D., Medical Oncology Service, Chair, Thoracic Oncology, Lausanne University Hospital, Lausanne, Switzerland. ?In this aggressive cancer that historically has had limited treatment options, we?ve now not only seen the potential for patients to live longer with nivolumab plus ipilimumab, but that this benefit is sustained at three years compared to treatment with chemotherapy. These results give us further proof of the durability of the outcomes achieved with this combination.? At three years of follow-up and approximately one year of being off treatment per protocol, more patients who responded to?Opdivo?plus?Yervoy?remained in response than those treated with chemotherapy, and duration of response (DOR) was longer with the dual immunotherapy combination, regardless of histology:

• 28% of patients who responded to?Opdivo?plus?Yervoy?remained in response at three years compared to no patients (0%) in the chemotherapy arm.
• Those treated with the dual immunotherapy combinationhad a median DOR of 11.6 months, compared to 6.7 months with chemotherapy.
• Objective response rate (ORR) in patients treated with the combination was comparable to chemotherapy (39.6% vs. 44.0%, respectively).

?The results from the CheckMate -743 trial have changed the way physicians treat malignant pleural mesothelioma, a disease that had no new systemic treatment options for nearly 15 years before the approval of?Opdivo?plus?Yervoy,? said Abderrahim Oukessou, M.D., vice president, thoracic cancers development lead, Bristol Myers Squibb. ?We continue to see more evidence for the sustained survival benefits of dual immunotherapy across several tumors, including durable overall survival at four years in non-small cell lung cancer. Now, the combination has demonstrated long-term improvements in overall survival in mesothelioma, another thoracic cancer, extending the lives of patients with a devastating disease.? Opdivo?plus?Yervoy?has received approval for use in first-line unresectable MPM from 14 health authorities around the world, including in the U.S., European Union, Japan and China. Additional regulatory applications are under review globally. Opdivo?plus?Yervoy-based combinations have shown significant improvements in OS in six Phase 3 clinical trials in five tumors to date: malignant pleural mesothelioma, non-small cell lung cancer, metastatic melanoma, advanced renal cell carcinoma and esophageal squamous cell carcinoma. About CheckMate -743 CheckMate -743 is an open-label, multi-center, randomized Phase 3 trial evaluating?Opdivo?plus?Yervoy?compared to chemotherapy (pemetrexed and cisplatin or carboplatin) in patients with previously untreated unresectable malignant pleural mesothelioma (n=605). In the trial, 303 patients were randomized to receive?Opdivo?at 3 mg/kg every two weeks and?Yervoy?at 1 mg/kg every six weeks; 302 patients were randomized to receive cisplatin 75 mg/m²?or carboplatin AUC 5 plus pemetrexed 500 mg/m²?in 21-day cycles for six cycles. Treatment in both arms continued until disease progression or unacceptable toxicity or, in the?Opdivo?plus?Yervoy?arm, up to 24 months. The primary endpoint of the trial was overall survival (OS) in all randomized patients. Additional efficacy outcome measures included progression-free survival (PFS), objective response rate (ORR) and duration of response (DOR), as assessed by blinded independent central review (BICR) utilizing modified RECIST criteria. Exploratory endpoints included safety, pharmacokinetics, immunogenicity and patient reported outcomes. About Malignant Pleural Mesothelioma Malignant pleural mesothelioma is a rare but aggressive form of cancer that forms in the lining of the lungs. It is most frequently caused by exposure to asbestos. Diagnosis is often delayed, with the majority of patients presenting with advanced or metastatic disease. Prognosis is generally poor: in previously untreated patients with advanced or metastatic malignant pleural mesothelioma, median survival is between 12 and 14 months and the five-year survival rate is approximately 10%.

Because as a leader in cancer care, Bristol Myers Squibb is working to empower all people with cancer to have a better future. 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 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.

IMPORTANT SAFETY INFORMATION Severe and Fatal Immune-Mediated Adverse Reactions Immune-mediated adverse reactions listed herein may not include 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 after discontinuation of OPDIVO or YERVOY. Early identification and management are essential to ensure safe use of OPDIVO and 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 periodically during treatment with OPDIVO and before each dose of YERVOY. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate. Withhold or permanently discontinue OPDIVO and YERVOY depending on severity (please see section 2 Dosage and Administration in the accompanying Full Prescribing Information). In general, if OPDIVO or YERVOY interruption or discontinuation is required, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose immune-mediated adverse reactions are not controlled with corticosteroid therapy. Toxicity management guidelines for adverse reactions that do not necessarily require systemic steroids (e.g., endocrinopathies and dermatologic reactions) are discussed below. Immune-Mediated Pneumonitis OPDIVO and YERVOY can cause immune-mediated pneumonitis. The incidence of pneumonitis is higher in patients who have received prior thoracic radiation. In patients receiving OPDIVO monotherapy, immune-mediated pneumonitis occurred in 3.1% (61/1994) of patients, including Grade 4 (<0.1%), Grade 3 (0.9%), and Grade 2 (2.1%). In patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg every 3 weeks, immune-mediated pneumonitis occurred in 7% (31/456) of patients, including Grade 4 (0.2%), Grade 3 (2.0%), and Grade 2 (4.4%). In patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg every 3 weeks, immune-mediated pneumonitis occurred in 3.9% (26/666) of patients, including Grade 3 (1.4%) and Grade 2 (2.6%). In NSCLC patients receiving OPDIVO 3 mg/kg every 2 weeks with YERVOY 1 mg/kg every 6 weeks, immune-mediated pneumonitis occurred in 9% (50/576) of patients, including Grade 4 (0.5%), Grade 3 (3.5%), and Grade 2 (4.0%). Four patients (0.7%) died due to pneumonitis. 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, including Grade 3 (n=1) and Grade 2 (n=12). Immune-Mediated Colitis OPDIVO and YERVOY can cause immune-mediated colitis, which may be fatal. A common symptom included in the definition of colitis was diarrhea. 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. In patients receiving OPDIVO monotherapy, immune-mediated colitis occurred in 2.9% (58/1994) of patients, including Grade 3 (1.7%) and Grade 2 (1%). In patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg every 3 weeks, immune-mediated colitis occurred in 25% (115/456) of patients, including Grade 4 (0.4%), Grade 3 (14%) and Grade 2 (8%).

OPDIVO in combination with cabozantinib can cause hepatic toxicity with higher frequencies of Grade 3 and 4 ALT and AST elevations compared to OPDIVO alone. Consider more frequent monitoring of liver enzymes as compared to when the drugs are administered as single agents. In patients receiving OPDIVO and cabozantinib, Grades 3 and 4 increased ALT or AST were seen in 11% of patients. Immune-Mediated Endocrinopathies OPDIVO and YERVOY can cause primary or secondary adrenal insufficiency, immune-mediated hypophysitis, immune-mediated thyroid disorders, and Type 1 diabetes mellitus, which can present with diabetic ketoacidosis. Withhold OPDIVO and YERVOY depending on severity (please see section 2 Dosage and Administration in the accompanying Full Prescribing Information). For Grade 2 or higher adrenal insufficiency, initiate symptomatic treatment, including hormone replacement as clinically indicated. Hypophysitis can present with acute symptoms associated with mass effect such as headache, photophobia, or visual field defects. Hypophysitis can cause hypopituitarism; initiate hormone replacement as clinically indicated. Thyroiditis can present with or without endocrinopathy. Hypothyroidism can follow hyperthyroidism; initiate hormone replacement or medical management as clinically indicated. Monitor patients for hyperglycemia or other signs and symptoms of diabetes; initiate treatment with insulin as clinically indicated. In patients receiving OPDIVO monotherapy, adrenal insufficiency occurred in 1% (20/1994), including Grade 3 (0.4%) and Grade 2 (0.6%).

Other Immune-Mediated Adverse Reactions The following clinically significant immune-mediated adverse reactions occurred at an incidence of <1% (unless otherwise noted) in patients who received OPDIVO monotherapy or OPDIVO in combination with YERVOY or were reported with the use of other PD-1/PD-L1 blocking antibodies. Severe or fatal cases have been reported for some of these adverse reactions:?cardiac/vascular:?myocarditis, pericarditis, vasculitis;?nervous system:?meningitis, encephalitis, myelitis and demyelination, myasthenic syndrome/myasthenia gravis (including exacerbation), Guillain-Barr? syndrome, nerve paresis, autoimmune neuropathy;?ocular:?uveitis, iritis, and other ocular inflammatory toxicities can occur;?gastrointestinal:?pancreatitis to include increases in serum amylase and lipase levels, gastritis, duodenitis;?musculoskeletal and connective tissue:?myositis/polymyositis, rhabdomyolysis, and associated sequelae including renal failure, arthritis, polymyalgia rheumatica;?endocrine:?hypoparathyroidism;?other (hematologic/immune):?hemolytic anemia, aplastic anemia, hemophagocytic lymphohistiocytosis (HLH), systemic inflammatory response syndrome, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), sarcoidosis, immune thrombocytopenic purpura, solid organ transplant rejection. In addition to the immune-mediated adverse reactions listed above, across clinical trials of YERVOY monotherapy or in combination with OPDIVO, the following clinically significant immune-mediated adverse reactions, some with fatal outcome, occurred in <1% of patients unless otherwise specified:?nervous system:?autoimmune neuropathy (2%), myasthenic syndrome/myasthenia gravis, motor dysfunction;?cardiovascular:?angiopathy, temporal arteritis;?ocular: blepharitis, episcleritis, orbital myositis, scleritis;?gastrointestinal:?pancreatitis (1.3%);?other (hematologic/immune):?conjunctivitis, cytopenias (2.5%), eosinophilia (2.1%), erythema multiforme, hypersensitivity vasculitis, neurosensory hypoacusis, psoriasis. Some ocular IMAR cases can be associated with retinal detachment. Various grades of visual impairment, including blindness, can occur. If uveitis occurs in combination with other immune-mediated adverse reactions, consider a Vogt-Koyanagi-Harada?like syndrome, which has been observed in patients receiving OPDIVO and YERVOY, as this may require treatment with systemic corticosteroids to reduce the risk of permanent vision loss. Infusion-Related Reactions OPDIVO and YERVOY can cause severe infusion-related reactions. Discontinue OPDIVO and YERVOY in patients with severe (Grade 3) or life-threatening (Grade 4) infusion-related reactions. Interrupt or slow the rate of infusion in patients with mild (Grade 1) or moderate (Grade 2) infusion-related reactions. In patients receiving OPDIVO monotherapy as a 60-minute infusion, infusion-related reactions occurred in 6.4% (127/1994) of patients. In a separate trial in which patients received OPDIVO monotherapy as a 60-minute infusion or a 30-minute infusion, infusion-related reactions occurred in 2.2% (8/368) and 2.7% (10/369) of patients, respectively. Additionally, 0.5% (2/368) and 1.4% (5/369) of patients, respectively, experienced adverse reactions within 48 hours of infusion that led to dose delay, permanent discontinuation or withholding of OPDIVO. In melanoma patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg every 3 weeks, infusion-related reactions occurred in 2.5% (10/407) of patients. In HCC patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg every 3 weeks, infusion-related reactions occurred in 8% (4/49) of patients. In RCC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg every 3 weeks, infusion-related reactions occurred in 5.1% (28/547) of patients. In MSI-H/dMMR mCRC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg every 3 weeks, infusion-related reactions occurred in 4.2% (5/119) of patients. In MPM patients receiving OPDIVO 3 mg/kg every 2 weeks with YERVOY 1 mg/kg every 6 weeks, infusion-related reactions occurred in 12% (37/300) of patients. Complications of Allogeneic Hematopoietic Stem Cell Transplantation Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with OPDIVO or YERVOY. Transplant-related complications include hyperacute graft-versus-host-disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease (VOD) after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between OPDIVO or YERVOY and allogeneic HSCT. Follow patients closely for evidence of transplant-related complications and intervene promptly. Consider the benefit versus risks of treatment with OPDIVO and YERVOY prior to or after an allogeneic HSCT. Embryo-Fetal Toxicity Based on its mechanism of action and findings from animal studies, OPDIVO and YERVOY can cause fetal harm when administered to a pregnant woman. The effects of YERVOY are likely to be greater during the second and third trimesters of pregnancy. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with OPDIVO and YERVOY and for at least 5 months after the last dose. Increased Mortality in Patients with Multiple Myeloma when OPDIVO is Added to a Thalidomide Analogue and Dexamethasone In randomized clinical trials in patients with multiple myeloma, the addition of OPDIVO to a thalidomide analogue plus dexamethasone resulted in increased mortality. Treatment of patients with multiple myeloma with a PD-1 or PD-L1 blocking antibody in combination with a thalidomide analogue plus de
