The Food and Drug Administration has approved daratumumab in combination with certain therapies for newly diagnosed patients with multiple myeloma who are eligible for autologous stem cell transplant.
The approval specifies combination of this CD38-directed antibody with bortezomib (Velcade), thalidomide, and dexamethasone (VTd), according to an announcement from Janssen.
The approval is based on results from thestudy. The first part of the study randomized 1,085 patients (median age, 58 years) and showed that, compared with VTd alone, the daratumumab-VTd combination had significantly better postconsolidation stringent complete response (29% vs. 20%; odds ratio, 1.60; 95% confidence interval, 1.21-2.12; P = .001) and a 53% reduction in risk of disease progression or death (hazard ratio, 0.47; 95% CI, 0.33-0.67; P = .0001).
The most frequent adverse reactions with 5% greater frequency in the daratumumab-VTd group were infusion reactions (including anaphylaxis), nausea, pyrexia, upper respiratory tract infection, and bronchitis. Full, including contraindications and warnings, can be found on the Janssen website.
Daratumumab was initially approved in 2015, and in June 2019, it received, in combination with lenalidomide and dexamethasone, for treatment of patients with newly diagnosed multiple myeloma who are ineligible for autologous stem cell transplant.
