In which countries is Darzalex Faspro approved?

Overview of Darzalex Faspro
Darzalex Faspro is a subcutaneous formulation of daratumumab, a human monoclonal antibody that targets the CD38 molecule, which is highly expressed on multiple myeloma cells. Its formulation is co‐administered with recombinant human hyaluronidase PH20 (rHuPH20), a key component of Halozyme’s ENHANZE drug delivery technology, which facilitates the dispersion and absorption of the injected drug and therefore enables faster and more convenient administration compared to traditional intravenous infusions. This scientific innovation has not only enhanced patient convenience—with injection times reduced to just a few minutes—but also maintained the clinical efficacy observed in intravenous formulations, ultimately expanding the therapeutic reach for both multiple myeloma and light chain amyloidosis.

Composition and Mechanism of Action
The composition of Darzalex Faspro is rooted in its two principal components. First, daratumumab acts as the active monoclonal antibody that binds with high affinity to CD38, triggering immune-mediated tumor cell death through several mechanisms including complement-dependent cytotoxicity, antibody-dependent cellular cytotoxicity, and apoptosis induction. Second, the inclusion of hyaluronidase enhances the permeability of the subcutaneous tissue, thus enabling the effective dispersion of daratumumab into the tissue and rapid systemic absorption after subcutaneous injection. This innovative combination not only maintains the pharmacodynamics observed with the intravenous formulation but also ensures a more patient-friendly dosing regimen with a substantially shorter administration time, reducing the patients’ time spent in clinical settings.

Therapeutic Indications
Darzalex Faspro has been evaluated and approved for a broad spectrum of therapeutic indications. Primarily, it is indicated for the treatment of multiple myeloma under various settings – including newly diagnosed patients (both transplant-eligible and transplant-ineligible) and relapsed or refractory cases. In addition, it is specifically approved for the treatment of light chain (AL) amyloidosis, a rare and often life-threatening disorder associated with the deposition of amyloid proteins in vital organs. In the United States, for example, Darzalex Faspro was granted accelerated approval for light chain amyloidosis in combination with a specific therapeutic regimen. The multiple clinical studies, such as the APOLLO trial, have demonstrated significant improvements in progression-free survival and overall treatment outcomes when daratumumab is used in combination with other established chemotherapeutic agents, underscoring its vital role in modern therapeutic protocols.
