What Is Darzalex Faspro?
Darzalex Faspro®, a combination of Darzalex and hyaluronidase (an endoglycosidase), is a formulation given as an abdominal injection under the skin (subcutaneous, SQ) to treat adult patients with multiple myeloma. It has been determined to be as effective as the original formulation of Darzalex. Switching from IV to SQ must first be discussed with your doctor.
Who Is a Candidate for Darzalex Faspro?
Darzalex Faspro is used in myeloma as part of the following treatments:
- In combination with Velcade® (bortezomib), melphalan, and prednisone (DVMP) in newly diagnosed patients who are ineligible for autologous stem cell transplant (ASCT).
- In combination with Revlimid® (lenalidomide) and dexamethasone in newly diagnosed patients who are ineligible for ASCT, and in patients with relapsed and refractory myeloma who have received at least one prior therapy.
- In combination with Velcade, thalidomide, and dexamethasone in newly diagnosed patients eligible for ASCT.
- In combination with Velcade and dexamethasone in patients who have received at least one prior therapy.
- In combination with Pomalyst® and dexamethasone in patients who have received at least one prior line of therapy including Revlimid and a proteasome inhibitor.
- As monotherapy in patients who have received at least 3 prior lines of therapy, including a proteasome inhibitor and an immunomodulatory drug, or who are double-refractory (no longer responded) to a proteasome inhibitor and an immunomodulatory drug.
How Is Darzalex Faspro Given?
Darzalex Faspro is given by a healthcare professional as an abdominal SQ injection that takes only a few minutes (3-5 minutes). The dose is 1,800 mg of daratumumab plus 30,000 units hyaluronidase. Medications may be given before and after each injection to help prevent a reaction.
