For older, transplant-ineligible myeloma patients, quadruplet regimens are not administered at full strength. Clinicians proactively reduce doses of bortezomib, lenalidomide, and dexamethasone based on patient fitness and renal function to manage toxicity while maintaining efficacy.
The clinical decision for newly diagnosed, transplant-ineligible myeloma patients has fundamentally shifted. Instead of determining who is eligible for a quadruplet regimen, the primary question for clinicians is now identifying the few patients who are not fit enough for this new standard of care.
With highly effective treatments like CAR-T and bispecifics moving into earlier lines of therapy for multiple myeloma, the clinical focus must evolve. While efficacy benchmarks have been met, the next advancement requires vigilant attention to safety, particularly infection risks and other side effects of new paradigms.
