DARZALEX FASPRO® contains 1,800 mg of daratumumab and 30,000 units of hyaluronidase in a 15 mL solution. Recombinant hyaluronidase increases permeability of subcutaneous tissue, enabling 1,800 mg of daratumumab to be absorbed into the subcutaneous tissue of the abdomen.1
DARZALEX FASPRO® is for subcutaneous use only.1
Monitor patients for systemic ARRs, especially following the first and second injections. For anaphylactic reaction or life-threatening (Grade 4) ARRs, immediately and permanently discontinue DARZALEX FASPRO®.1
Ocular adverse reactions, including acute myopia and narrowing of the anterior chamber angle due to ciliochoroidal effusions with potential for increased intraocular pressure or glaucoma, have occurred with daratumumab-containing products. If ocular symptoms occur, interrupt DARZALEX FASPRO® and seek immediate ophthalmologic evaluation prior to restarting DARZALEX FASPRO®.1
Pre- and post-administration/
infusion medications and dose modifications1,2
To reduce the risk of ARRs/IRRs, administration of pre- and post-administration/infusion medications is recommended. No dose reductions of DARZALEX FASPRO® or DARZALEX® are recommended. Dose delay may be required to allow recovery of blood cell counts in the event of hematological toxicity.
Pre-administration/infusion medications1,2
- Dexamethasone 20 mg prior to every DARZALEX FASPRO® or DARZALEX® infusion orally or intravenously. When dexamethasone is the background regimen-specific corticosteroid, the dexamethasone treatment dose will also serve as pre-medication on days DARZALEX FASPRO® or DARZALEX® is given
- During monotherapy, methylprednisolone 100 mg, or equivalent, administered orally or intravenously. Following the second administration/infusion of DARZALEX FASPRO® or DARZALEX®, respectively, the dose of corticosteroid may be reduced (oral or intravenous methylprednisolone 60 mg)
- Oral antipyretics (acetaminophen 650 to 1000 mg)
- Oral or IV antihistamine (diphenhydramine 25 to 50 mg or equivalent)
Post-administration/infusion medications1,2
- Oral corticosteroid (≤20 mg methylprednisolone or equivalent); however, if a background regimen-specific corticosteroid (eg, dexamethasone, prednisone) is administered the day after the DARZALEX FASPRO® or DARZALEX® administration/infusion, additional post-administration/infusion medications may not be needed
- During monotherapy, administer oral corticosteroid (20 mg methylprednisolone or equivalent dose of an intermediate-acting or long-acting corticosteroid in accordance with local standards) on each of the 2 days following all DARZALEX FASPRO® or DARZALEX® administrations/infusions (beginning the day after the administration/infusion)
Other administration/infusion-related considerations
Interference with serological testing2
- Daratumumab binds to CD38 on red blood cells (RBCs) and results in a positive indirect antiglobulin test (indirect Coombs test)
- Daratumumab-mediated positive indirect antiglobulin test may persist for up to 6 months after the last daratumumab infusion
- Daratumumab bound to RBCs masks detection of antibodies to minor antigens in the patient’s serum. The determination of a patient’s ABO and Rh blood type is not impacted
Reminders
- Type and screen patients before starting DARZALEX®
- Inform blood banks when a patient is on DARZALEX®
- Identify any blood samples of patients treated with DARZALEX®
- Ask patients to tell other healthcare professionals that they've taken DARZALEX®
Prophylaxis for herpes zoster reactivation2
Initiate antiviral prophylaxis to prevent herpes zoster reactivation within 1 week after starting DARZALEX® and continue for 3 months following treatment.
Hepatitis B reactivation2
Hepatitis B reactivation: Hepatitis B virus reactivation has been reported in less than 1% of patients (including fatal cases) treated with DARZALEX® in clinical trials. Advise patients to inform healthcare providers if they have ever had or might have a hepatitis B infection and that DARZALEX® could cause hepatitis B virus to become active again.
Interference with determination of complete response (CR)2
Daratumumab is a human immunoglobulin G (IgG) kappa monoclonal antibody (mAb) that can be detected on serum protein electrophoresis (SPE) and immunofixation (IFE) assays, which can impact the determination of a CR and of disease progression in some patients with IgG kappa myeloma protein.
- To facilitate administration, the first prescribed 16 mg/kg dose at Week 1 may be split over 2 consecutive days. See full Prescribing Information to learn more about split first dose2
- DARZALEX® should be administered by a healthcare professional with immediate access to emergency equipment and appropriate medical support to manage infusion reactions if they occur2
- If a planned dose of DARZALEX® is missed, administer the dose as soon as possible and adjust the dosing schedule accordingly, maintaining the treatment interval2
- Shortness of breath or trouble breathing
- Dizziness or lightheadedness (hypotension)
- Cough
- Wheezing
- Heart beating faster than usual
- Low oxygen in the blood (hypoxia)
- Throat tightness or irritation
- Runny or stuffy nose
- Headache
- Itching
- High blood pressure
- Nausea
- Vomiting
- Chills
- Fever
- Chest discomfort
- Blurred vision
