Dexamethasone Regimen Significantly Reduces IRRs in Lung Cancer
New Insights from the SKIPPirr Study on Dexamethasone
Recent findings reveal that administering an 8 mg pre-medication regimen of dexamethasone prior to intravenous amivantamab treatment significantly reduced the incidence of infusion-related reactions (IRRs) in patients with advanced non-small cell lung cancer (NSCLC) carrying epidermal growth factor receptor (EGFR) mutations. The study showed an IRR rate of just 22.5 percent, a remarkable drop from the 67.4 percent historically recorded with previous standard management strategies.
Background Information on Amivantamab
Amivantamab, a fully human bispecific antibody, is utilized to target tumors with activating and resistance mutations of EGFR, along with MET mutations and amplifications. This therapy has received attention not only for its effectiveness but also for the infusion-related issues it can cause, particularly noted by the European Medicines Agency (EMA).
Prophylactic Treatments Evaluated
The SKIPPirr study was an open-label Phase 2 trial looking into additional prophylactic measures to lower IRRs associated with IV amivantamab. Participants received oral dexamethasone over two days leading up to their first infusion, which yielded an impressive reduction in IRRs. Three other treatment arms were included in the study, testing various prophylactic approaches. However, groups employing 4 mg dexamethasone, montelukast, and methotrexate were halted due to lack of efficacy.
Understanding the Study Results
Alongside the main regimen, the study found that all recorded IRRs were of Grade 1 or 2 severity, and no patients required hospitalization as a result. Notably, only mild symptoms were observed, including nausea and hypotension, further emphasizing the safety of the dexamethasone regimen.
Expert Insights on Treatment Effects
Dr. Gilberto Lopes, the Associate Director of Global Oncology at the Sylvester Comprehensive Cancer Center, expressed optimism about these findings. He highlighted that the new approach of using a higher dose of dexamethasone not only improved the treatment experience for patients but also points to a significant decrease in the expected rate of IRRs. This aligns with Johnson & Johnson's dedication to enhancing care quality for patients battling EGFR-mutated NSCLC.
Future Directions for IRR Strategies
Ongoing research aims to evaluate further prophylactic strategies to support patients receiving amivantamab. These efforts are crucial to ensuring that patients can undergo treatment with reduced side effects and disruptions, ultimately improving their overall experience.
Commitment to Cancer Treatment Innovation
In the midst of these advancements, team members at Johnson & Johnson emphasize their commitment to innovative patient care. Through research such as the SKIPPirr study, they continue to explore alternatives to enhance treatment delivery and minimize adverse reactions.
