A landmark advancement in lung cancer treatment has emerged from a recently published phase 3 clinical trial in the prestigious New England Journal of Medicine. The study reveals that incorporating the immunotherapy drug nivolumab in combination with standard chemotherapy before surgical intervention markedly enhances long-term survival for patients diagnosed with non-small cell lung cancer (NSCLC), the most prevalent subtype of this deadly disease. This trial, known as CheckMate 816, was led by Professor Patrick Forde at the Trinity St. James’s Cancer Institute (TSJCI) in Dublin, and involved 358 patients worldwide. Its findings challenge prior assumptions, establishing immunotherapy not just as a palliative option in advanced disease but as a potential curative adjunct in earlier-stage lung cancer management.
NSCLC has long posed a formidable challenge to oncologists, especially in stages 2 and 3, where surgical resection remains the cornerstone of curative treatment. Unfortunately, more than half of patients undergoing surgery eventually experience cancer relapse, highlighting the urgent need for therapies that can eradicate microscopic residual disease and improve the chances of durable remission. Immunotherapy drugs, particularly immune checkpoint inhibitors targeting the PD-1 receptor, have revolutionized treatment in metastatic cancers by enabling the immune system to recognize and destroy tumor cells more effectively. However, until now, convincing evidence demonstrating long-term survival benefits of these agents in the neoadjuvant (pre-surgical) setting for lung cancer was lacking.

Professor Forde, who pioneered neoadjuvant immunotherapy research during his tenure at Johns Hopkins University in the United States, emphasized the significance of these findings. His seminal 2018 study, published also in the New England Journal of Medicine, was the first to show that neoadjuvant immunotherapy could drastically reduce tumor burden prior to surgery, with almost half of patients exhibiting minimal or no residual disease following treatment. The evolving data from CheckMate 816 thus represents a natural progression, translating initial biological efficacy into clear survival benefits in a much larger cohort.
Building on the success of CheckMate 816, ongoing research strives to further optimize neoadjuvant strategies. Among these efforts is the international NeoCOAST-2 trial, co-led by Professor Forde and open to patient enrollment at multiple Irish centers such as TSJCI, Beaumont, Galway, and Mater Hospitals. This innovative study explores the addition of an antibody-drug conjugate (ADC)—a novel targeted therapy designed to deliver cytotoxic agents directly to cancer cells—as a supplementary treatment alongside chemo-immunotherapy. Preliminary results, published recently in the highly regarded Nature Medicine, indicate a higher probability of achieving pCR with this triple combination, suggesting substantial promise for improving patient outcomes even further.
The introduction of immunotherapy in the neoadjuvant setting addresses a critical unmet need by reducing the risk of disease recurrence — a major driver of mortality in patients with resectable lung cancer. These therapies act by lifting the immunosuppressive “cloak” that tumors deploy to evade immune detection, specifically through blockade of PD-1, a checkpoint receptor found on T-cells. Upon activation by nivolumab, the immune system can mount a more effective antitumor response, eradicating micrometastases that would otherwise lead to relapse despite surgical removal of the primary tumor.
Beyond the clinical implications, these breakthroughs underscore the importance of cancer clinical trials in accelerating innovation and expanding treatment options. Prof. Forde highlights that trials such as CheckMate 816 and NeoCOAST-2 are invaluable not only for establishing new standards but also for granting patients earlier access to cutting-edge therapies, something particularly vital in a disease as aggressive as lung cancer. His role as the Patrick Prendergast Professor of Clinical Immuno-Oncology at Trinity College Dublin reflects the commitment to fostering research excellence and translational medicine.
The CheckMate 816 trial’s design as a randomized controlled clinical trial ensures the robustness and reliability of its findings, which are now shaping global clinical guidelines. As more data accumulate, clinicians will gain a better understanding of optimal patient selection and the sequencing of therapies in the multidisciplinary management of NSCLC. Meanwhile, ongoing trials like NeoCOAST-2 signal a continued evolution toward more effective, tailored immunotherapeutic strategies that may one day establish new benchmarks for cure.
In summary, the growing body of evidence demonstrates that neoadjuvant nivolumab plus chemotherapy significantly improves long-term survival and reduces relapse rates in patients with resectable NSCLC. This represents a transformative advance in lung cancer care, shifting immunotherapy from late-stage disease to the frontline of curative treatment. As these approaches become more widely adopted and further refined, they offer the promise of markedly improved outcomes for patients worldwide who face this devastating diagnosis.
