Introduction
DARZALEX FASPRO (daratumumab) is a subcutaneous formulation of the monoclonal antibody daratumumab, developed by Janssen Pharmaceuticals, targeting CD38. Originally approved as an intravenous (IV) infusion, the subcutaneous (SC) version offers enhanced patient convenience and reduced administration time. Given its expanding indications in multiple myeloma (MM) and promising clinical data, DARZALEX FASPRO’s trajectory warrants close examination within current clinical, commercial, and regulatory landscapes.
Clinical Trials Landscape and Updates
Current and Ongoing Clinical Trials
Daratumumab's clinical development spans various stages and indications. The pivotal phase III trials underpinning DARZALEX FASPRO’s approval include:
-
COLUMBA (NCT03514783): Demonstrates non-inferiority of subcutaneous daratumumab plus standard regimens versus IV infusion in relapsed/refractory multiple myeloma (RRMM) patients. The trial results confirmed comparable efficacy with significantly reduced administration time, bolstering data for SC formulation acceptance.
-
POLLUX (NCT02076009): Validates daratumumab combined with lenalidomide and dexamethasone in transplant-ineligible MM, with ongoing sub-studies evaluating SC administration optimization.
-
ICARIA-MM (NCT03154452): Assesses daratumumab with pomalidomide and dexamethasone, a critical combination especially post-relapse. The ongoing phase III evaluates further enhancements in efficacy and side effect profiles.
Other trials are underway exploring daratumumab’s utility across additional hematologic malignancies like smoldering multiple myeloma and amyloidosis, with promising preliminary data.
Recent Clinical Milestones
-
FDA Approval of DARZALEX FASPRO (2020): Marked as an important milestone, the approval was based on the phase III COLUMBA trial, confirming the non-inferiority of SC administration regarding efficacy and safety versus IV. The approval expanded DARZALEX’s administration options, emphasizing patient-centric care.
-
Extended Indications: Subsequent approvals have included first-line treatment settings, combining DARZALEX FASPRO with bortezomib and dexamethasone, reinforcing its position in frontline therapy.
Safety and Efficacy
The safety profile of DARZALEX FASPRO mirrors the IV formulation. Common adverse events include infusion-related reactions (IRRs), predominantly mild to moderate, which are significantly decreased with SC administration due to reduced infusion time and immune engagement. Efficacy endpoints such as overall response rate (ORR), progression-free survival (PFS), and minimal residual disease (MRD) negativity scores support its clinical viability.
