Improving Lung Cancer Responses with BMS Immunotherapy: Phase 3 Study
A recent study conducted in Barcelona, Spain has shown promising results in improving responses for certain patients with a type of lung cancer by adding a second immunotherapy from Bristol Myers Squibb (BMS) to an existing checkpoint inhibitor and chemotherapy. This exciting development has now propelled the approach into a Phase 3 study, marking a significant step forward in the treatment of this deadly disease.
The Phase 2 RELATIVITY-104 trial focused on testing BMS’ Opdualag, a combination of the company’s powerful PD-1 inhibitor Opdivo and relatlimab, which targets another checkpoint called LAG-3. While Opdualag has already been approved for use in advanced melanoma, it has faced challenges in certain colorectal and liver cancer indications. However, the results of this new study have reignited hope for its potential in treating advanced non-small cell lung cancer.
The study compared the efficacy of Opdualag with chemotherapy against Opdivo and chemotherapy alone as a first-line treatment for advanced non-small cell lung cancer. The goal was to identify which patients would benefit most from the addition of the anti-LAG-3 drug to the standard backbone of chemotherapy and immunotherapy. Samit Hirawat, BMS’s chief medical officer, highlighted the importance of this research in determining the optimal treatment approach for patients with this aggressive form of lung cancer.

The Power of Combination Therapies
Combination therapies have become a cornerstone in the treatment of various types of cancer, including lung cancer. By targeting multiple pathways involved in tumor growth and immune evasion, these therapies have shown great promise in improving outcomes for patients. The addition of Opdualag to the standard treatment regimen in the RELATIVITY-104 trial represents a novel approach to enhancing the immune response against cancer cells.
Dr. Hirawat explained that the rationale behind combining Opdivo and relatlimab is to leverage the synergistic effects of targeting both PD-1 and LAG-3 checkpoints. By inhibiting these immune checkpoints, the immune system is unleashed to mount a more robust attack against cancer cells. This dual mechanism of action holds great potential for enhancing the efficacy of immunotherapy in lung cancer patients.
Understanding the Role of LAG-3 in Lung Cancer
LAG-3, or lymphocyte-activation gene 3, is a protein that plays a critical role in regulating the immune response. It is often upregulated on exhausted T cells, which are immune cells that have become dysfunctional and unable to effectively target cancer cells. By targeting LAG-3 with relatlimab, researchers aim to reinvigorate these exhausted T cells and enhance their ability to recognize and destroy cancer cells.
The decision to investigate the role of LAG-3 in lung cancer was driven by the need to identify alternative treatment strategies for patients who do not respond well to existing therapies. By understanding the molecular pathways involved in immune evasion, researchers can develop targeted therapies that address the specific weaknesses of the tumor microenvironment. The results of the RELATIVITY-104 trial are a testament to the potential of LAG-3 as a therapeutic target in lung cancer.
Implications for the Future of Lung Cancer Treatment
The findings from the Phase 2 RELATIVITY-104 trial have significant implications for the future of lung cancer treatment. By demonstrating the efficacy of Opdualag in combination with chemotherapy, researchers have opened up new possibilities for improving outcomes in patients with advanced non-small cell lung cancer. The results of this study pave the way for a Phase 3 trial to further evaluate the benefits of this novel treatment approach.
Dr. Hirawat emphasized the importance of personalized medicine in lung cancer treatment, highlighting the need to identify biomarkers that can predict which patients are most likely to benefit from specific therapies. By tailoring treatment plans to individual patients based on their unique genetic and molecular profiles, oncologists can optimize outcomes and minimize side effects. The ongoing research into immunotherapy combinations like Opdualag offers hope for a future where lung cancer is more effectively managed and potentially cured.
In conclusion, the Phase 2 RELATIVITY-104 trial has demonstrated the potential of combining Opdivo and relatlimab in improving responses for patients with advanced non-small cell lung cancer. This innovative approach holds promise for enhancing the efficacy of immunotherapy and chemotherapy in treating this challenging disease. As research advances and new treatments are developed, the outlook for patients with lung cancer continues to improve, offering hope for a brighter future in the fight against this deadly illness.
