FDA Approves Subcutaneous Daratumumab Combo Regimen for Second-Line Multiple Myeloma
The FDA approval of daratumumab plus hyaluronidase-fihj (Darzalex Faspro) plus pomalidomide and dexamethasone (Pd) was supported by data from the APOLLO trial.
Adult patients with multiple myeloma who have received at least 1 prior line of therapy, including lenalidomide (Revlimid) and a proteasome inhibitor, are now able to be treated with daratumumab plus hyaluronidase-fihj (Darzalex Faspro) plus pomalidomide and dexamethasone (Pd) following an FDA approval.
The regulatory decision was supported by data from the phase 3 APOLLO trial (NCT01960348), which showed that the combination regimen resulted in a significant reduction in the risk of progression or death compared with Pd alone in this patient population.
The median progression-free survival in the investigative arm was 12.4 months vs 6.9 months in the control arm (HR, 0.63; 95% CI, 0.47-0.85; P = .0018); this translated to a 37% reduction. Moreover, the overall response rate proved to be higher with the addition of daratumumab plus hyaluronidase-fihj to Pd vs Pd alone, at 69% vs 46%, respectively. Complete response rates in the investigative and control arms were 25% vs 4%, respectively, and partial response rates were 51% vs 20%, respectively.
“Clinical studies including APOLLO have continued to show the ability of daratumumab-based combination treatment regimens to significantly reduce the risk of progression in patients with multiple myeloma,” Meletios A. Dimopoulos, MD, professor and chairman of the 2 Department of Clinical Therapeutics at the National and Kapodistrian University of Athens School of Medicine, Athens, Greece, and principal investigator, stated in a press release. “With this approval, we are now able to combine pomalidomide and dexamethasone with a daratumumab subcutaneous option that can be administered in minutes rather than the hours needed for intravenous administration.”
