On May 10, 2024 Bristol Myers Squibb (NYSE: BMY) reported the Phase 3 CheckMate -73L trial did not meet its primary endpoint of progression-free survival (PFS) in unresectable, locally advanced stage III non-small cell lung cancer (NSCLC) (Press release, Bristol-Myers Squibb, MAY 10, 2024, View Source;73L-Trial/default.aspx [SID1234643076]). CheckMate -73L evaluated Opdivo (nivolumab) with concurrent chemoradiotherapy (CCRT) followed by Opdivo plus Yervoy (ipilimumab) versus CCRT followed by durvalumab in patients with unresectable stage III NSCLC. The observed adverse events of Opdivo with CCRT followed by Opdivo plus Yervoy were generally consistent with the known profiles of each component in the regimen.

"Unfortunately, adding immunotherapy concurrently with definitive chemoradiation did not improve PFS outcomes in this setting," said Joseph Fiore, vice president, global program lead, thoracic cancers, Bristol Myers Squibb. "There remains a critical need to improve long-term outcomes for these patients and we believe these results will help inform future drug development efforts in this setting. We want to thank the patients, families and investigators for their contributions to this important research."

The company will complete a full evaluation of the data and work with investigators to share the results with the scientific community.

Opdivo and Opdivo-based combinations have shown positive outcomes and are approved treatment options for eligible patients with resectable or metastatic NSCLC.

About CheckMate -73L

CheckMate -73L is a Phase 3 randomized, open label trial evaluating Opdivo in combination with concurrent chemoradiotherapy (CCRT), followed by Opdivo plus Yervoy, or Opdivo (monotherapy), compared to CCRT alone followed by durvalumab, in patients with previously untreated, locally advanced stage III non-small cell lung cancer (NSCLC) that are not intended or eligible for curative surgery. A total of 925 patients were randomized to receive specified doses on specified days of either Opdivo in combination with CCRT followed by Opdivo plus Yervoy (Arm A), Opdivo in combination with CCRT followed by Opdivo monotherapy (Arm B), or CCRT followed by durvalumab (Arm C). The primary endpoint of the trial is progression-free survival (PFS) by RECIST 1.1 per blinded independent central review (BICR) for Arm A vs. Arm C. Secondary endpoints include overall survival (OS) across the study arms, PFS by RECIST 1.1 per BICR across the study arms, as well as objective response rate (ORR), time to response (TTR) and duration of response (DOR) per RECIST 1.1 per BICR, and additional safety and efficacy endpoints.

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.
