Janssen Files sBLA for Datzalex in Multiple Myeloma

Share

Janssen Biotech has submitted a supplemental BLA for Darzalex (daratumumab) and its expanded use in combination with bortezomib, melphalan and prednisone for treating patients with newly diagnosed multiple myeloma who are ineligible for autologous stem cell transplantation. Darzalex was first approved 11/2015 as a monotherapy for patients with multiple myeloma who have received at least three prior lines of therapy.

 

The new submission is based on Phase 3 data from the ALCYONE study of daratumumab in combination with Velcade (bortezomib), melphalan and prednisone (VMP) in front line multiple myeloma. The study met the primary endpoint of improving progression free survival (PFS), and treatment with daratumumab reduced the risk of disease progression or death by 50%, as compared to those who did not receive daratumumab, according to the company. “The median PFS for patients treated with daratumumab in combination with VMP has not been reached, compared to an estimated median PFS of 18.1 months for patients who received VMP alone,” it says. “Overall, the safety profile of daratumumab in combination with VMP is consistent with the known safety profile of the VMP regimen and the known safety profile of daratumumab.”
