The faculty consider how to apply belantamab mafodotin in community practice, where clinicians typically see fewer patients with myeloma and want clear guidance and quick decisions. They discuss the therapy options available to patients and how access and distance from an academic center may shape the choice. They note that antibody-drug conjugates are familiar from other cancers, such as solid tumors and lymphomas, and proceed to describe an approach of assessing response and eye side effects after the first doses and then delaying or spacing doses as needed if the patient is responding to treatment.

Wade T. Iams, MD, of Tennessee Oncology, says the stability of skin toxicity rates across 8.3 months of COPERNICUS follow-up, with 86% of participants still on study, gives him the most confidence in subcutaneous amivantamab plus lazertinib, and the near elimination of infusion reactions carries the most weight.

Siddhartha Devarakonda, MD, of Providence Swedish Cancer Institute says he tries not to push patients with asymptomatic brain metastases from epidermal growth factor receptor (EGFR)-mutated advanced non–small cell lung cancer (NSCLC) toward local therapy, calling whole brain radiation the wrong step for this patient and noting that another consultation costs the patient time.

Estelamari Rodriguez, MD, MPH, of Sylvester Comprehensive Cancer Center presents a 68-year-old woman with newly diagnosed metastatic lung adenocarcinoma, an epidermal growth factor receptor (EGFR) exon 19 deletion with a concurrent TP53 co-mutation, multiple small asymptomatic brain metastases on staging magnetic resonance imaging, disease confined to lung and brain, and good performance status with support at home.

The faculty turn to the safety and practical aspects of using belantamab mafodotin, drawing on earlier experience with the drug. They discuss how lines of therapy are defined and whether the definition needs refinement, and how efficacy endpoints translate into clinical relevance. Health-related quality of life is reviewed, with the view that good disease control is a driver of better quality of life. The panel describes holding the drug for eye symptoms, restarting at a lower dose, and adjusting dosing frequency to keep responding patients on therapy. They also note the overall response rate and MRD negativity in the study and discuss their interpretation of the data.
