摘要
ObjectivesHeavily pretreated patients with relapsed and refractory multiple myeloma are susceptible to treatment-related adverse events (AEs). Managing AEs are important to ensure patients continue therapy long enough to receive the best clinical benefit. Data from the MM-002, MM-003, and MM-010 trials were pooled to further characterize the safety profile of pomalidomide plus low-dose dexamethasone and AE management. MethodsThis analysis included 1088 patients who received 2 prior therapies, including lenalidomide and bortezomib, and progressed 60days of last therapy. Patients received 28-day cycles of pomalidomide 4mg/day on days 1-21 and low-dose dexamethasone 40mg (20mg if aged > 75years) weekly until disease progression or unacceptable toxicity. Thromboprophylaxis was required. ResultsThe most common grade 3/4 AEs were neutropenia (56.2%), anemia (32.3%), and thrombocytopenia (25.8%), which occurred within the first few cycles of treatment. Grade 3/4 infections occurred in 33.7% patients, of whom 13.9% had pneumonia, and 40.3% had neutropenia. Pomalidomide dose reductions or interruptions were reported in 24.2% and 66.0% of patients, respectively. AEs were managed by dose modifications and/or supportive care. ConclusionsPomalidomide plus low-dose dexamethasone showed an acceptable safety profile, and AEs were well managed according to study protocols and established guidelines.
