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.

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.
