CheckMate -743 remains the only Phase 3 trial to show a survival improvement – now sustained over three years – with first-line immunotherapy treatment in patients with unresectable malignant pleural mesothelioma

Data to be featured in a Proffered Paper session during the 2021 European Society for Medical Oncology Virtual Congress

Mesothelioma is the fourth tumor type in which Opdivo plus Yervoy has demonstrated durable, superior survival with three years or more of follow-up

PRINCETON, NJ, USA I September 13, 2021 IBristol 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%.

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.
