In this episode, Drs. Rahul & Rohit Gosain discussed the evolving landscape of metastatic non-small cell lung cancer (NSCLC) with mutated EGFR disease. We discussed the significant advancements in treatment options, particularly focusing on the recent data from the MARIPOSA trial, which evaluated the combination of amivantamab and lazertinib.
We started by outlining the current treatment options available for our patients: osimertinib, osimertinib with chemotherapy, and the new combination of amivantamab with lazertinib. Dr. Susan Scott provided an overview of the efficacy and tolerability of osimertinib, which has been the standard of care for several years, and highlighted the promising results from the FLAURA-2 and MARIPOSA studies.
Dr. Joshua Sabari elaborated on the MARIPOSA trial's design and the unique mechanism of action of amivantamab, a bispecific EGFR and MET antibody. We also discussed the importance of monitoring CNS disease, as over 50% of patients with EGFR mutations develop brain metastases. Dr. Helena Yu emphasized the need for proactive CNS imaging to catch asymptomatic progression early.
Dr. Estela Rodriguez shared insights on managing side effects associated with these treatments, particularly cutaneous toxicities and thromboembolism. We explored strategies for proactive management, including premedication and patient education on skin care.
As we navigated the complexities of treatment decisions, we considered factors such as disease burden, patient preferences, and the potential for resistance mechanisms. The conversation highlighted the importance of tailoring treatment plans to individual patient needs, especially for those with high-risk features.
In summary, we reflected on the promising data supporting the use of amivantamab and lazertinib, which have shown improved progression-free survival and overall survival compared to traditional therapies. However, we also stressed the importance of managing side effects and maintaining a proactive approach to patient care. This episode served as a comprehensive overview of the current state of EGFR-mutated NSCLC treatment and the exciting developments on the horizon.
