Darzalex Faspro Drug Information

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Newly Diagnosed Multiple Myeloma Eligible for Autologous Stem Cell Transplant In Combination with Bortezomib, Lenalidomide and Dexamethasone The safety of DARZALEX FASPRO in combination with bortezomib, lenalidomide and dexamethasone (n=351) from the start of induction to the end of consolidation compared to bortezomib, lenalidomide and dexamethasone (VRd) (n=347) was evaluated in PERSEUS . Patients received DARZALEX FASPRO 1,800 mg/30,000 units administered subcutaneously once weekly from weeks 1 to 8 and once every 2 weeks from weeks 9 to 16 during induction in combination with VRd or VRd alone. After week 16, patients underwent stem cell mobilization, high dose chemotherapy, and ASCT. Within 12 weeks of ASCT, and when engraftment was complete, patients received DARZALEX FASPRO once every 2 weeks from weeks 1 to 8 during consolidation in combination with VRd or VRd alone.

The median duration of treatment for induction and consolidation was 9.9 months (0.5 to 18.5 months) for DARZALEX FASPRO-VRd. Serious adverse reactions occurred in 37% of patients who received DARZALEX FASPRO-VRd. The most frequent serious adverse reaction in >5% of patients who received DARZALEX FASPRO-VRd was pneumonia (6%). Fatal adverse reactions occurred in 1.7% of patients who received DARZALEX FASPRO-VRd.

Permanent treatment discontinuation due to an adverse reaction occurred in 2% of patients who received DARZALEX FASPRO-VRd. An adverse reaction which resulted in permanent discontinuation of DARZALEX FASPRO-VRd in more than 1 patient included sepsis. The most common adverse reactions (≥20%) were peripheral neuropathy, fatigue, upper respiratory infection, constipation, musculoskeletal pain, insomnia, rash, diarrhea, edema, and pyrexia.

Postmarketing Experience

The following adverse reactions have been identified with post-approval use of daratumumab. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Immune System : Anaphylactic reaction, Systemic administration reactions (including death) Gastrointestinal: Pancreatitis Infections: Cytomegalovirus, Listeriosis

Effects of Daratumumab on Laboratory Tests Interference with Indirect Antiglobulin Tests (Indirect

Coombs Test) Daratumumab binds to CD38 on RBCs and interferes with compatibility testing, including antibody screening and cross matching. Daratumumab interference mitigation methods include treating reagent RBCs with dithiothreitol (DTT) to disrupt daratumumab binding or genotyping. Since the Kell blood group system is also sensitive to DTT treatment, supply K-negative units after ruling out or identifying alloantibodies using DTT-treated RBCs.

If an emergency transfusion is required, administer non-cross-matched ABO/RhD-compatible RBCs per local blood bank practices. Interference with Serum Protein Electrophoresis and Immunofixation Tests Daratumumab may be detected on serum protein electrophoresis (SPE) and immunofixation (IFE) assays used for monitoring disease monoclonal immunoglobulins (M protein). False positive SPE and IFE assay results may occur for patients with IgG kappa myeloma protein impacting initial assessment of complete responses by International Myeloma Working Group (IMWG) criteria. In DARZALEX FASPRO-treated patients with persistent very good partial response, where daratumumab interference is suspected, consider using a FDA-approved daratumumab-specific IFE assay to distinguish daratumumab from any remaining endogenous M protein in the patient's serum, to facilitate determination of a complete response.

Pregnancy Risk Summary DARZALEX FASPRO can cause fetal harm when administered to a pregnant woman. The assessment of associated risks with daratumumab products is based on the mechanism of action and data from target antigen CD38 knockout animal models (see Data ). There are no available data on the use of DARZALEX FASPRO in pregnant women to evaluate drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. Animal reproduction studies have not been conducted.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. The combination of DARZALEX FASPRO and lenalidomide, thalidomide or pomalidomide is contraindicated in pregnant women, because lenalidomide, thalidomide and pomalidomide may cause birth defects and death of the unborn child. Lenalidomide, thalidomide and pomalidomide are only available through a REMS program.

Refer to the lenalidomide, thalidomide or pomalidomide prescribing information on use during pregnancy. Clinical Considerations Fetal/Neonatal Adverse Reactions Immunoglobulin G1 (IgG1) monoclonal antibodies are transferred across the placenta. Based on its mechanism of action, DARZALEX FASPRO may cause depletion of fetal CD38 positive immune cells and decreased bone density.

Defer administering live vaccines to neonates and infants exposed to daratumumab in utero until a hematology evaluation is completed. Data Animal Data DARZALEX FASPRO for subcutaneous injection contains daratumumab and hyaluronidase. Mice that were genetically modified to eliminate all CD38 expression (CD38 knockout mice) had reduced bone density at birth that recovered by 5 months of age.

Data from studies using CD38 knockout animal models also suggest the involvement of CD38 in the regulation of humoral immune responses (mice), feto-maternal immune tolerance (mice), and early embryonic development (frogs). No systemic exposure of hyaluronidase was detected in monkeys given 220,000 U/kg subcutaneously (440 times higher than the human dose) and there were no effects on embryo-fetal development in pregnant mice given 360,000 U/kg hyaluronidase subcutaneously daily during organogenesis, which is 720 times higher than the human dose. There were no effects on pre- and post-natal development through sexual maturity in offspring of mice treated daily from implantation through lactation with 1,100,000 U/kg hyaluronidase subcutaneously, which is 2,200 times higher than the human doses.

Pediatric Use Safety and effectiveness of DARZALEX FASPRO in pediatric patients have not been established.

is contraindicated in patients with a history of severe hypersensitivity to daratumumab, hyaluronidase or any of the components of the formulation. Patients with a history of severe hypersensitivity to daratumumab, hyaluronidase or any of the components of the formulation.
