Daratumumab was granted FDA approval on 16 November 2015. It is approved for the treatment of multiple myeloma as monotherapy or combination therapy and light chain (AL) amyloidosis in combination with other drugs.

Indication

Daratumumab is indicated as an intravenous injection alone or in combination with other medications for the treatment of multiple myeloma. It is available as a combination product with hyaluronidase for the treatment of adults with multiple myeloma as monotherapy or combination therapy and light chain amyloidosis in combination with other drugs.

FDA Advisory Committee Votes 6-2 in Favor of Daratumumab for High-Risk Smoldering Multiple Myeloma

• The FDA's Oncologic Drug Advisory Committee (ODAC) voted 6-2 that daratumumab (Darzalex Faspro) demonstrates a favorable benefit-risk profile for patients with high-risk smoldering multiple myeloma, potentially offering the first approved therapy for this precursor condition. • The phase 3 AQUILA trial showed daratumumab significantly delayed progression to active multiple myeloma with a 51% reduction in risk of progression or death compared to active monitoring, with 5-year PFS rates of 63.1% versus 40.8%. • Committee members expressed concerns about risk classification accuracy and potential overtreatment, but ultimately determined the benefits outweighed risks for this malignant condition that has an 80% five-year progression risk to symptomatic multiple myeloma.

FDA's Approval of MRD as End Point Transforms Multiple Myeloma Research and Treatment

• The FDA's Oncology Drugs Advisory Committee unanimously approved minimal residual disease (MRD) as an end point for accelerated approval of multiple myeloma therapies in April 2024, potentially reducing trial timelines from 10-15 years to just 3 years. • Pharmaceutical companies have rapidly adapted by implementing MRD as a coprimary end point in new trials and amending existing protocols, with the CEPHEUS trial being the first major study to read out with MRD as a coprimary endpoint. • Researchers are now exploring MRD applications beyond drug approval, including using MRD status to guide treatment decisions, developing improved blood-based detection technologies, and expanding the approach to other hematologic malignancies.

Optimizing Treatment Strategies for Relapsed Multiple Myeloma: From CAR T-Cell Therapy to Novel Combinations

• CAR T-cell therapy has emerged as a valuable option for multiple myeloma patients after first relapse when they are lenalidomide-refractory, with careful consideration needed for pre-treatment strategies to optimize outcomes. • Experts recommend avoiding BCMA-targeted therapies before BCMA-directed CAR T-cell therapy, as this can lead to lower response rates and progression-free survival, while non-BCMA bispecifics like talquetamab may be effective bridging options. • Selinexor-based combinations, including selinexor/pomalidomide/dexamethasone and selinexor/carfilzomib/dexamethasone, show promising efficacy in heavily pretreated patients with response rates of 50-65% and progression-free survival ranging from 6-15 months.

GSK's Blenrep Secures UK Approval for Multiple Myeloma Treatment in Combination Therapy

• The UK's medicines regulatory body has approved GSK's Blenrep (belantamab mafodotin) in combination with other drugs for multiple myeloma patients whose first treatment failed or caused severe side effects. • This approval marks a significant comeback for Blenrep, which was withdrawn from markets in 2022 after failing to outperform existing treatments when used as monotherapy. • Clinical trials demonstrated Blenrep's combination therapy extended progression-free survival and overall survival compared to standard care regimens, including those based on Darzalex (daratumumab).

DARZALEX® Subcutaneous Regimen Receives CHMP Backing for Newly Diagnosed Multiple Myeloma Treatment

• Johnson & Johnson's DARZALEX® subcutaneous formulation combined with VRd receives positive CHMP recommendation for treating newly diagnosed multiple myeloma patients, regardless of transplant eligibility. • The recommendation is supported by the Phase 3 CEPHEUS study, which evaluated the efficacy of daratumumab-VRd compared to VRd alone in 395 patients with newly diagnosed multiple myeloma. • DARZALEX® has demonstrated significant impact in multiple myeloma treatment, having been used in over 618,000 patients worldwide and currently approved in eight indications.

Daratumumab Plus VRd Improves Outcomes in Transplant-Ineligible Multiple Myeloma Patients

• The phase 3 CEPHEUS trial demonstrated that adding daratumumab to VRd significantly improved outcomes for transplant-ineligible newly diagnosed multiple myeloma patients. • The quadruplet regimen achieved a 60.9% minimal residual disease (MRD) negativity rate compared to 39.4% with VRd alone, demonstrating a significant increase in treatment depth. • Progression-free survival was also significantly improved with the daratumumab regimen, showing a 43% reduction in the risk of disease progression or death. • These results suggest that daratumumab plus VRd could become a new standard of care for transplant-ineligible multiple myeloma patients, offering improved disease control.

GSK's Blenrep Demonstrates Significant Survival Benefit in Multiple Myeloma Trial, Paving Way for Potential Comeback
