Carfilzomib, a selective second-generation proteasome inhibitor, has performed well in clinical trials. So because other “triplets”—combinations of alkylator, proteasome inhibitor, and steroid—had shown “encouraging” response rates, researchers from the Center for Cancer and Blood Disorders in Bethesda, Maryland, and others, conducted a multicenter study to evaluate the safety and tolerability of twice-weekly carfilzomib combined with cyclophosphamide and dexamethasone (KCyd) for patients newly diagnosed with multiple myeloma (MM).
The researchers tested 3 doses of carfilzomib: 36 mg/m2, 45 mg/m2, and 56 mg/m2. Of the 22 enrolled patients, 16 were treated with the maximum dose.
Fourteen patients completed all 8 cycles of treatment; 10 in the maximum-dose group completed all 8. At 56 mg/m2, the overall response rate was 87.5%. Among the 14 patients whose disease responded to therapy, the median time to response was 1 month.
Five patients discontinued treatment because of adverse effects (AEs), but the researchers found no dose-limiting toxicities at any of the dose levels. The most common AEs were nausea, diarrhea, and anemia.
The researchers concluded that based on previous research, KCyd with 36 mg/m2 is safe and effective in patients aged ≥ 65 years with newly diagnosed MM. However, their findings suggest that twice-weekly carfilzomib 56 mg/m2 in combination with cyclophosphamide and dexamethasone also is effective with “manageable toxicity.”
