In 2024, significant advancements have been made in the understanding, prevention, and treatment of lung cancer. These developments encompass novel therapeutic approaches, improved patient outcomes, and enhanced preventive strategies.
Recent Discoveries in Lung Cancer Treatment
- Subcutaneous Formulation of Keytruda: Merck & Co. Inc. announced promising results from a Phase 3 trial of a new subcutaneous formulation of its leading cancer drug, Keytruda. The trial revealed that this new method of administration, combined with chemotherapy, is as effective as the traditional intravenous method. This development could help Merck maintain its market position as Keytruda, which generates significant revenue (approximately $25 billion in 2023), faces patent expiration in 2028. The new subcutaneous version, which can be administered in 2-3 minutes, enhances patient experience and accessibility. Merck plans to discuss these findings with regulators globally. Additionally, Merck is conducting further trials to evaluate the subcutaneous formulation alone against the intravenous method for certain lung cancer patients. MarketWatch
- Merck’s Licensing Deal with LaNova Medicines: Merck has secured an up to $3.3 billion licensing deal with China’s LaNova Medicines for a cancer drug, aimed at countering competition from Summit Therapeutics’ ivonescimab. Merck will pay $588 million upfront for LaNova’s LM-299, with the potential for up to $2.7 billion in milestone payments. Ivonescimab, developed in partnership with Akeso, had outperformed Merck’s Keytruda in a lung cancer study, prompting concerns over Keytruda’s market dominance. LM-299 and ivonescimab both block PD-1 and VEGF proteins to combat cancer, while Keytruda blocks PD-1 alone. This strategic move by Merck is seen as an insurance policy and a way to potentially extend Keytruda’s supremacy beyond its patent expiration. Initial data shows ivonescimab’s effectiveness in increasing progression-free survival, sparking investor focus on its impact on overall survival rates. Analyst Umer Raffat considers the deal a savvy business move by Merck, anticipating rapid progress despite LM-299 being in the early testing phase. Investors.com
- COVID-19’s Potential Anti-Cancer Properties: A new study from researchers in Illinois has discovered that COVID-19 may have a positive side effect—it can potentially shrink tumors. Scientists found that the ribonucleic acid (RNA) molecules of the SARS-CoV-2 virus activate a special immune cell known as inducible nonclassical monocytes (I-NCMs), which possess anti-cancer properties. These cells have the unique ability to infiltrate tumours and attack cancer cells directly, which normal immune cells cannot do. Initially effective against melanoma, lung, breast, and bowel cancers, this finding suggests a novel approach for treating resistant cancers. Further research and clinical trials are necessary to confirm these findings. This discovery is complemented by advancements where salmonella bacteria are being studied for their potential to combat bowel cancer. The article also emphasizes the importance of cancer screenings, detailing the availability and procedures for cervical, breast, and bowel cancer screenings in England. Regular screenings can detect cancer or its risk early, enhancing the likelihood of successful treatment. The Scottish Sun
- Amivantamab and Lazertinib Combination Therapy: A newly approved drug combination by the FDA has shown to extend progression-free survival in advanced lung cancer patients by over 40% compared to the current standard treatment. In a large trial funded by Janssen, patients receiving amivantamab (a monoclonal antibody) and lazertinib (a tyrosine kinase inhibitor) had an average progression-free survival of 23.7 months versus 16.6 months with the standard drug osimertinib. This breakthrough is being celebrated by experts and is seen as part of a “golden age” of cancer research where deeper understanding of cancer biology is leading to more effective treatments. The trial involved more than 1,000 advanced non-small cell lung cancer patients across various countries between 2020 and 2022. The FDA approved this new treatment in August. New York Post
- Lorlatinib for ALK-Positive Lung Cancer: A new daily tablet called lorlatinib offers hope for long-term survival to patients with ALK-positive lung cancer, an incurable form of the disease. Presented at the American Society of Clinical Oncology conference, a trial revealed that 60% of patients taking lorlatinib survived five years without cancer growth, versus 8% on standard treatment. Developed by Pfizer, lorlatinib is a “growth-blocking” tyrosine kinase inhibitor that binds to the ALK protein, halting tumor growth signals. The study involved 296 patients, some with brain-spread cancer, and showed lorlatinib’s effectiveness in preventing brain tumor progression. The trial results highlight lorlatinib’s potential to become a first-line treatment for ALK-positive lung cancer, pending approval by the National Institute for Health and Care Excellence (Nice). This breakthrough marks significant progress in lung cancer care by enabling prolonged, progression-free survival. The Times
Advancements in Early Detection and Prevention
Early detection remains a cornerstone in improving lung cancer outcomes. The American Lung Association’s new 2024 “State of Lung Cancer” report ranks New York in the top 5 states for early diagnosis, surgery, and survival. The American Lung Association says the national lung cancer survival rate has risen 26% in the last five years due to increased awareness and advancements in detection and treatment.
Traditional Treatment Modalities
Despite these advancements, traditional treatments such as surgery, chemotherapy, and radiation therapy continue to play vital roles in lung cancer management. The integration of these methods with novel therapies offers a comprehensive approach to treatment, tailored to individual patient profiles.
