Opdivo demonstrated significant overall survival benefit over chemotherapy alone in both PD-L1 positive and all-randomized populations in both treatment arms

CheckMate -648 marks the third global trial in which Opdivo demonstrated a significant benefit for patients with upper gastrointestinal cancers

Data to be featured in an oral presentation during the 2021 American Society of Clinical Oncology (ASCO) Annual Meeting

PRINCETON, NJ, USA I June 04, 2021 I Bristol Myers Squibb (NYSE: BMY) today announced results from the Phase 3 CheckMate -648 trial, in which two Opdivo-based treatment combinations — Opdivo (nivolumab) plus chemotherapy and Opdivo plus Yervoy (ipilimumab) — demonstrated a statistically significant and clinically meaningful overall survival (OS) benefit compared to chemotherapy at the pre-specified interim analysis in patients with unresectable advanced or metastatic esophageal squamous cell carcinoma (ESCC) with tumor cell PD-L1 expression ≥1%, as well as in the all-randomized population. Opdivo plus Yervoy is the first dual immunotherapy combination to demonstrate a superior survival benefit versus chemotherapy in this setting. The data will be presented in an oral session on Saturday, June 5, 2021 from 1:45 p.m. to 4:45 p.m. EDT and featured in the official press program during the 2021 American Society of Clinical Oncology (ASCO) Annual Meeting.

For the combination of Opdivo plus chemotherapy, median OS was 15.4 months vs. 9.1 months for chemotherapy in patients whose tumors express PD-L1, a primary endpoint (hazard ratio [HR] 0.54, 99.5% CI: 0.37-0.80, p<0.0001), and 13.2 months vs. 10.7 months in the all-randomized patient population, a secondary endpoint (HR 0.74, 99.1% CI: 0.58-0.96, p=0.0021). A statistically significant progression-free survival (PFS) benefit was also observed with Opdivo plus chemotherapy in patients whose tumors express PD-L1, with a median PFS by blinded independent central review (BICR) of 6.9 months compared to 4.4 months with chemotherapy alone (HR 0.65, 98.5% CI: 0.46-0.92, p=0.0023).

For the combination of Opdivo plus Yervoy, median OS was 13.7 months vs. 9.1 months for chemotherapy in patients whose tumors express PD-L1, a primary endpoint (HR 0.64, 98.6% CI: 0.46-0.90, p=0.001), and 12.8 months vs. 10.7 months, respectively, in the all-randomized patient population, a secondary endpoint (HR 0.78, 98.2% CI: 0.62-0.98, p=0.011). Opdivo plus Yervoy did not meet its other primary endpoint of PFS by BICR in patients whose tumors express PD-L1 (4.0 months vs. 4.4 months; HR 1.02, 98.5% CI: 0.73-1.43, p=0.8958).

The safety profiles of Opdivo plus chemotherapy and Opdivo plus Yervoy were consistent with those previously reported for other tumor types. Grade 3/4 drug-related adverse events were 47% in the Opdivo plus chemotherapy arm, 32% in the Opdivo plus Yervoy arm, and 36% in the chemotherapy arm. The safety profile in patients with PD-L1 ≥1% was consistent with the all-randomized data.

“Patients with advanced esophageal squamous cell carcinoma face a median survival of around 10 months when treated with chemotherapy alone and there is a clear need for treatment options beyond this current standard of care,” said Ian Chau, M.D., Consultant Medical Oncologist, The Royal Marsden NHS Foundation Trust. “The data being presented at ASCO show that both of these nivolumab-based treatment options resulted in significant improvements in survival over chemotherapy and could offer potential new treatment options.”

The median duration of response (DoR) per BICR was 8.4 months for Opdivo plus chemotherapy, 11.8 months for Opdivo plus Yervoy, and 5.7 months for chemotherapy alone in patients whose tumors express PD-L1, and 8.2 months, 11.1, and 7.1 months, respectively, in the all-randomized population.

Opdivo plus chemotherapy also showed a clinically meaningful increase in objective response rate (ORR). The ORR per BICR was 53% for Opdivo plus chemotherapy, 35% for Opdivo plus Yervoy, and 20% for chemotherapy alone in patients whose tumors express PD-L1 and 47%, 28% and 27%, respectively, in the all-randomized population.

CheckMate –648 is the first global Phase 3 study to evaluate both an immunotherapy and chemotherapy combination as well as a dual immunotherapy combination in advanced ESCC.

“These data add to our growing body of evidence supporting the clinical benefit of Opdivo in upper GI cancers, from the late-line metastatic setting to earlier stages of disease,” said Ian M. Waxman, M.D., development lead, gastrointestinal cancers, Bristol Myers Squibb. “Opdivo has now demonstrated superior first-line efficacy in multiple upper GI cancers across histologies and tumor locations.”

About CheckMate -648

CheckMate -648 is a randomized Phase 3 study evaluating Opdivo plus Yervoy or Opdivo plus fluorouracil and cisplatin against fluorouracil plus cisplatin alone in patients with unresectable advanced or metastatic esophageal squamous cell carcinoma.

The primary endpoints of the trial are overall survival (OS) and progression-free survival (PFS) by blinded independent central review (BICR) in patients whose tumors express PD-L1 ≥1% for both Opdivo-based combinations versus chemotherapy. Secondary endpoints of the trial include OS and PFS by BICR in the all-randomized population.

In the Opdivo plus chemotherapy arm (N=321), patients received treatment with Opdivo 240 mg on Day 1 and Day 15, fluorouracil 800 mg/m²/day on Day 1 through Day 5 (for 5 days), and cisplatin 80 mg/m² on Day 1 of four-week cycle. Patients received Opdivo for up to 24 months or until disease progression or unacceptable toxicity, and chemotherapy until disease progression or unacceptable toxicity.

In the Opdivo plus Yervoy arm (N=325), patients received treatment with Opdivo 3 mg/kg every 2 weeks and Yervoy 1 mg/kg every 6 weeks up to 24 months or until disease progression or unacceptable toxicity.

About Esophageal Cancer

Esophageal cancer is the eighth most common cancer and the sixth leading cause of death from cancer worldwide, with approximately 604,000 new cases and over 544,000 deaths in 2020. The two most common types of esophageal cancer are squamous cell carcinoma (ESCC) and adenocarcinoma, which account for approximately 90% and 10% of all esophageal cancers, respectively, though esophageal tumor histology can vary by region. The overall burden of ESCC is concentrated in Asia, where roughly 80% of the global cases occurred in 2020. The majority of esophageal cancer cases are diagnosed in the advanced setting and impact a patient’s daily life, including their ability to eat and drink. ESCC occurs most often in the upper and middle portions of the esophagus, whereas adenocarcinoma begins in the cells of mucus-secreting glands in the esophagus and most often occurs in the lower portion of the esophagus.

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.
