BMY 30Mar2023 PR "Neoadjuvant Opdivo (nivolumab) with Chemotherapy Demonstrates

Long-Term, Durable Clinical Benefits for Patients with Resectable Non-Small Cell Lung Cancer at Three Years in the CheckMate -816 Trial

03/30/2023

Data to be featured in proffered paper oral session at ELCC 2023 show Opdivo and chemotherapy administered before surgery reduced the risk of disease recurrence, progression or death by 32% after three years of follow up

Updated results demonstrate long-term improvements in event-free survival and time to distant metastasis, as well as an encouraging trend toward overall survival, with neoadjuvant Opdivo and chemotherapy compared to chemotherapy alone

CheckMate -816 is the first positive Phase 3 trial with an immunotherapy-based combination in the neoadjuvant setting of NSCLC

PRINCETON, N.J.--(BUSINESS WIRE)-- Bristol Myers Squibb (NYSE: BMY) today announced three-year follow-up results from the Phase 3 CheckMate -816 trial, demonstrating sustained clinical benefits with three cycles of Opdivo (nivolumab) in combination with platinum-based chemotherapy for the neoadjuvant treatment of patients with resectable non-small cell lung cancer (NSCLC). With median follow up of 41.4 months, Opdivo with chemotherapy reduced the risk of disease recurrence, progression or death by 32%, demonstrating a landmark three-year event-free survival (EFS) rate of 57% with Opdivo with chemotherapy compared to 43% with chemotherapy alone (Hazard Ratio [HR], 0.68; 95% Confidence Interval [CI], 0.49 to 0.93). Additionally, time to distant metastasis or death (TTDM), defined as the time between the date of randomization and the first date of distant metastasis or the date of death in the absence of distant metastasis, continued to favor Opdivo with chemotherapy compared to chemotherapy alone (HR, 0.55; 95% CI, 0.39 to 0.78), with three-year landmark TTDM rates of 71% vs. 50%, respectively.

While overall survival (OS) remained immature at this analysis, there was a continued encouraging trend in OS favoring neoadjuvant Opdivo with chemotherapy over chemotherapy alone (HR 0.62; 99.34% CI: 0.36 to 1.05). At three years, 78% of patients treated with neoadjuvant Opdivo and chemotherapy were alive, compared to 64% with chemotherapy alone. OS will continue to be followed for upcoming analyses. These updated results will be featured in a proffered paper oral session at the European Lung Cancer Congress (ELCC) 2023 from March 29-April 1, 2023.

“These updated results from CheckMate -816 are immensely important, as they show that the addition of nivolumab to chemotherapy provides sustained efficacy over three years when given before surgery and provide hope for the large portion of patients with non-small cell lung cancer facing high recurrence rates and for whom cure is not feasible with surgery alone,” said Nicolas Girard, M.D., Ph.D., CheckMate -816 investigator and professor and head of the Thorax Institute Curie-Montsouris. “As the first positive Phase 3 trial with an immunotherapy-based combination in the neoadjuvant setting, the results from CheckMate -816 have already contributed valuable knowledge to the scientific community studying resectable NSCLC. Now, with long-term data showing the combination can continue helping to prevent disease recurrence and progression for different types of patients, alongside an encouraging trend of longer overall survival, this regimen is poised to change the way non-metastatic NSCLC is treated.”

Exploratory analyses included EFS by surgical approach, EFS by extent or completeness of resection, and EFS and pathologic complete response (pCR) by a four-gene (CD8A, CD274, STAT-1, LAG-3) inflammatory signature score derived from RNA sequencing of baseline tumor samples. Opdivo with chemotherapy continues to demonstrate improved EFS benefit at three years vs. chemotherapy in patients who had surgery, regardless of surgical approach or extent of resection, and in patients with R0 resection. In the Opdivo with chemotherapy arm, baseline four-gene inflammatory signature scores were numerically higher in patients with pCR compared to patients without and patients with higher baseline inflammatory scores appeared to have improved EFS with the combination, relative to those with lower scores.

After three years of follow up, the safety profile of neoadjuvant Opdivo with chemotherapy was consistent with the primary analysis, with no new safety signals observed. Grade 3-4 treatment-related and surgery-related adverse events occurred in 36% and 11% of patients in the Opdivo with chemotherapy arm, respectively, vs. 38% and 15% in the chemotherapy arm, respectively.

“The significant and sustained results from CheckMate -816 reinforce our commitment to research in earlier stages of cancers and our excitement around finding new options for earlier treatment, including in thoracic cancers with high remaining unmet needs like resectable non-small cell lung cancer,” said Abderrahim Oukessou, M.D., vice president, thoracic cancers development lead, Bristol Myers Squibb. “At BMS, we’ve been at the forefront of this transformational science and are proud to see additional data supporting the potential of immunotherapy-based approaches, including for the first time in the neoadjuvant treatment of resectable NSCLC with the science now translating to durable, long-term outcomes for patients that can reduce their risk for recurrence, progression and death.”

The pCR data from CheckMate -816 were initially presented at the 2021 American Association for Cancer Research (AACR) Annual Meeting. The EFS results and preliminary OS data were presented at the 2022 AACR Annual Meeting. Additionally, primary analyses of pCR, EFS and preliminary OS data were previously published in the New England Journal of Medicine. CheckMate -816 is ongoing to assess key secondary endpoints, including overall survival, which continues to mature.

Bristol Myers Squibb thanks the patients and investigators involved in the CheckMate -816 clinical trial.

About CheckMate -816

CheckMate -816 is a Phase 3 randomized, open label, multi-center trial evaluating Opdivo with chemotherapy compared to chemotherapy alone as neoadjuvant treatment in patients with resectable stage IB to IIIA non-small cell lung cancer (per the 7th edition American Joint Committee on Cancer/Union for International Cancer Control staging criteria), regardless of PD-L1 expression. For the primary analysis, 358 patients were randomized to receive either Opdivo 360 mg plus histology-based platinum doublet chemotherapy every three weeks for three cycles, or platinum doublet chemotherapy every three weeks for three cycles, followed by surgery. The primary endpoints of the trial are event-free survival and pathologic complete response. Secondary endpoints include overall survival, major pathologic response, and time to death or distant metastases.

About Lung Cancer

Lung cancer is the leading cause of cancer deaths globally. Non-small cell lung cancer (NSCLC) is one of the most common types of lung cancer, representing up to 84% of diagnoses. Non-metastatic cases account for the majority of NSCLC diagnoses (approximately 60%, with up to half of these being resectable), and the proportion is expected to grow over time with enhanced screening programs. While many non-metastatic NSCLC patients are cured by surgery, 30% to 55% develop recurrence and die of their disease despite resection, contributing to a need for treatment options administered before surgery (neoadjuvant) and/or after surgery (adjuvant) to improve long-term outcomes.
