Recommended Concomitant Medications

Pre-medication

Administer the following pre-medications 1–3 hours before each dose of DARZALEX FASPRO:

Acetaminophen 650 mg to 1,000 mg orally
Diphenhydramine 25 mg to 50 mg (or equivalent) orally or intravenously
Corticosteroid (long- or intermediate-acting)
Monotherapy
Administer methylprednisolone 100 mg (or equivalent) orally or intravenously. Consider reducing the dose of methylprednisolone to 60 mg (or equivalent) following the second dose of DARZALEX FASPRO.
In Combination
Administer dexamethasone 20 mg (or equivalent) orally or intravenously prior to every DARZALEX FASPRO administration.
When dexamethasone is the background regimen-specific corticosteroid, the dexamethasone dose that is part of the background regimen will serve as pre-medication on DARZALEX FASPRO administration days [see Clinical Studies (14)] .
Do not administer background regimen-specific corticosteroids (e.g. prednisone) on DARZALEX FASPRO administration days when patients have received dexamethasone (or equivalent) as a pre-medication.

Post-medication

Administer the following post-medications:

Monotherapy
Administer methylprednisolone 20 mg (or an equivalent dose of an intermediate- or long-acting corticosteroid) orally for 2 days starting the day after the administration of DARZALEX FASPRO.
In Combination
Consider administering oral methylprednisolone at a dose of less than or equal to 20 mg (or an equivalent dose of an intermediate- or long-acting corticosteroid) on the day after administration of DARZALEX FASPRO.
If a background regimen-specific corticosteroid (e.g., dexamethasone, prednisone) is administered the day after the administration of DARZALEX FASPRO, additional corticosteroids may not be needed [see Clinical Studies (14)] .

If the patient does not experience a major systemic administration-related reaction after the first 3 doses of DARZALEX FASPRO, consider discontinuing the administration of corticosteroids (excluding any background regimen-specific corticosteroid).

For patients with a history of chronic obstructive pulmonary disease, consider prescribing short and long-acting bronchodilators and inhaled corticosteroids. Following the first 4 doses of DARZALEX FASPRO, consider discontinuing these additional post-medications, if the patient does not experience a major systemic administration-related reaction.

Prophylaxis for Herpes Zoster Reactivation

Initiate antiviral prophylaxis to prevent herpes zoster reactivation within 1 week after starting DARZALEX FASPRO and continue for 3 months following the end of treatment [see Adverse Reactions (6.1)].

Dosage Modifications for Adverse Reactions

No dose reductions of DARZALEX FASPRO are recommended. Consider withholding DARZALEX FASPRO to allow recovery of blood cell counts in the event of myelosuppression [see Warnings and Precautions (5.3, 5.4)] .

Preparation and Administration

DARZALEX FASPRO should be administered by a healthcare provider.

To prevent medication errors, check the vial labels to ensure that the drug being prepared and administered is DARZALEX FASPRO for subcutaneous use. Do not administer DARZALEX FASPRO intravenously.

DARZALEX FASPRO is ready to use.

Preparation

Remove the DARZALEX FASPRO vial from refrigerated storage [2°C to 8°C (36°F to 46°F)] and equilibrate to ambient temperature [15°C to 30°C (59°F to 86°F)]. Store the unpunctured vial at ambient temperature and ambient light for a maximum of 24 hours. Keep out of direct sunlight. Do not shake.
Withdraw 15 mL from the vial into a syringe.
DARZALEX FASPRO is compatible with polypropylene or polyethylene syringe material; polypropylene, polyethylene, or polyvinyl chloride (PVC) subcutaneous infusion sets; and stainless steel transfer and injection needles. Use the product immediately.
After the solution of DARZALEX FASPRO is withdrawn into the syringe, replace the transfer needle with a syringe closing cap. Label the syringe appropriately to include the route of administration per institutional standards. Label the syringe with the peel-off label.
To avoid needle clogging, attach the hypodermic injection needle or subcutaneous infusion set to the syringe immediately prior to injection.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not use if opaque particles, discoloration or other foreign particles are present.

Storage

If the syringe containing DARZALEX FASPRO is not used immediately, store refrigerated at 2°C to 8°C (36°F to 46°F) for up to 24 hours and/or at room temperature at 15°C to 25°C (59°F to 77°F) for up to 12 hours under ambient light.
Discard if storage time exceeds these limits.
If stored in the refrigerator, allow the solution to come to room temperature before administration.

Administration

Inject 15 mL of DARZALEX FASPRO into the subcutaneous tissue of the abdomenapproximately 3 inches [7.5 cm] to the right or left of the navel over approximately 3–5 minutes. No data are available on performing the injection at other sites of the body.
Rotate injection sites for successive injections.
Never inject DARZALEX FASPRO into areas where the skin is red, bruised, tender, hard or areas where there are scars.
Pause or slow down delivery rate if the patient experiences pain. In the event pain is not alleviated by pausing or slowing down delivery rate, a second injection site may be chosen on the opposite side of the abdomen to deliver the remainder of the dose.
During treatment with DARZALEX FASPRO, do not administer other medications for subcutaneous use at the same site as DARZALEX FASPRO.

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.

The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. 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 uterountil 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 22,000 U/kg subcutaneously (12 times higher than the human dose) and there were no effects on embryo-fetal development in pregnant mice given 330,000 U/kg hyaluronidase subcutaneously daily during organogenesis, which is 45 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 990,000 U/kg hyaluronidase subcutaneously, which is 134 times higher than the human doses.

Lactation

Risk Summary

There is no data on the presence of daratumumab and hyaluronidase in human milk, the effects on the breastfed child, or the effects on milk production. Maternal immunoglobulin G is known to be present in human milk. Published data suggest that antibodies in breast milk do not enter the neonatal and infant circulations in substantial amounts. Because of the potential for serious adverse reactions in the breastfed child when DARZALEX FASPRO is administered with lenalidomide, thalidomide or pomalidomide, advise women not to breastfeed during treatment with DARZALEX FASPRO. Refer to lenalidomide, thalidomide or pomalidomide prescribing information for additional information.

Data

Animal Data

No systemic exposure of hyaluronidase was detected in monkeys given 22,000 U/kg subcutaneously (12 times higher than the human dose) and there were no effects on post-natal development through sexual maturity in offspring of mice treated daily during lactation with 990,000 U/kg hyaluronidase subcutaneously, which is 134 times higher than the human doses.

Females and Males of Reproductive Potential

DARZALEX FASPRO can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)] .

Pregnancy Testing

With the combination of DARZALEX FASPRO with lenalidomide, thalidomide or pomalidomide, refer to the lenalidomide, thalidomide or pomalidomide labeling for pregnancy testing requirements prior to initiating treatment in females of reproductive potential.

Contraception

Advise females of reproductive potential to use effective contraception during treatment with DARZALEX FASPRO and for 3 months after the last dose. Additionally, refer to the lenalidomide, thalidomide or pomalidomide labeling for additional recommendations for contraception.

Pediatric Use

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

Geriatric Use

Of the 291 patients who received DARZALEX FASPRO as monotherapy for relapsed and refractory multiple myeloma, 37% were 65 to <75 years of age, and 19% were 75 years of age or older. No overall differences in effectiveness of DARZALEX FASPRO have been observed between patients ≥65 years of age and younger patients .Adverse reactions that occurred at a higher frequency (≥5% difference) in patients ≥65 years of age included upper respiratory tract infection, urinary tract infection, dizziness, cough, dyspnea, diarrhea, nausea, fatigue, and peripheral edema. Serious adverse reactions that occurred at a higher frequency (≥2% difference) in patients ≥65 years of age included pneumonia.

Of the 214 patients who received DARZALEX FASPRO as combination therapy with pomalidomide and dexamethasone or DARZALEX FASPRO as combination therapy with lenalidomide and low-dose dexamethasone for relapsed and refractory multiple myeloma, 43% were 65 to <75 years of age, and 18% were 75 years of age or older. No overall differences in effectiveness were observed between patients ≥65 years (n=131) and <65 years (n=85). Adverse reactions occurring at a higher frequency (≥5% difference) in patients ≥65 years of age included fatigue, pyrexia, peripheral edema, urinary tract infection, diarrhea, constipation, vomiting, dyspnea, cough, and hyperglycemia. Serious adverse reactions occurring at a higher frequency (≥2% difference) in patients ≥65 years of age included neutropenia, thrombocytopenia, diarrhea, anemia, COVID-19, ischemic colitis, deep vein thrombosis, general physical health deterioration, pulmonary embolism, and urinary tract infection.

Of the 355 patients who were newly diagnosed with multiple myeloma and eligible for ASCT who received DARZALEX FASPRO as combination therapy with bortezomib, lenalidomide and dexamethasone during induction and consolidation in the clinical trial, 74% were <65 years of age, and 26% were 65 to 70 years of age. The clinical trial did not enroll patients older than 70 years of age [see Clinical Studies (14.1)] . No overall differences in effectiveness of DARZALEX FASPRO in combination with bortezomib, lenalidomide and dexamethasone were observed between patients <65 years of age compared to patients 65 to 70 years of age. Adverse reactions that occurred at a higher frequency (≥5% difference) in patients 65 to 70 years of age included constipation, hemorrhoids, nausea, injection site erythema, bronchitis, nasopharyngitis, back pain, myalgia, pain in extremity, dysgeusia, peripheral motor neuropathy, and insomnia. Serious adverse reactions that occurred at a higher frequency (≥2% difference) in patients 65 to 70 years of age included febrile bone marrow aplasia, atrial fibrillation, pyrexia, and orthostatic hypotension.

Of the 193 patients who received DARZALEX FASPRO as part of a combination therapy for light chain (AL) amyloidosis, 35% were 65 to <75 years of age, and 10% were 75 years of age or older. Clinical studies of DARZALEX FASPRO as part of a combination therapy for patients with light chain (AL) amyloidosis did not include sufficient numbers of patients aged 65 and older to determine whether effectiveness differs from that of younger patients. Adverse reactions that occurred at a higher frequency in patients ≥65 years of age were peripheral edema, asthenia, pneumonia and hypotension.

No clinically meaningful differences in the pharmacokinetics of daratumumab were observed in geriatric patients compared to younger adult patients [see Clinical Pharmacology (12.3)] .

Hypersensitivity and Other Administration Reactions

Both systemic administration-related reactions, including severe or life-threatening reactions, and local injection-site reactions can occur with DARZALEX FASPRO. Fatal reactions have been reported with daratumumab-containing products, including DARZALEX FASPRO [see Adverse Reactions (6.2)] .

Systemic Reactions

In a pooled safety population of 1249 patients with multiple myeloma (N=1056) or light chain (AL) amyloidosis (N=193) who received DARZALEX FASPRO as monotherapy or as part of a combination therapy, 7% of patients experienced a systemic administration-related reaction (Grade 2: 3.2%, Grade 3: 0.7%, Grade 4: 0.1%). Systemic administration-related reactions occurred in 7% of patients with the first injection, 0.2% with the second injection, and cumulatively 1% with subsequent injections. The median time to onset was 2.9 hours (range: 5 minutes to 3.5 days). Of the 165 systemic administration-related reactions that occurred in 93 patients, 144 (87%) occurred on the day of DARZALEX FASPRO administration. Delayed systemic administration-related reactions have occurred in 1% of the patients.

Severe reactions include hypoxia, dyspnea, hypertension, and tachycardia, and ocular adverse reactions, including choroidal effusion, acute myopia, and acute angle closure glaucoma. Other signs and symptoms of systemic administration-related reactions may include respiratory symptoms, such as bronchospasm, nasal congestion, cough, throat irritation, allergic rhinitis, and wheezing, as well as anaphylactic reaction, pyrexia, chest pain, pruritus, chills, vomiting, nausea, hypotension, and blurred vision.

Pre-medicate patients with histamine-1 receptor antagonist, acetaminophen and corticosteroids [see Dosage and Administration (2.5)] . Monitor patients for systemic administration-related reactions, especially following the first and second injections. For anaphylactic reaction or life-threatening (Grade 4) administration-related reactions, immediately and permanently discontinue DARZALEX FASPRO. Consider administering corticosteroids and other medications after the administration of DARZALEX FASPRO depending on dosing regimen and medical history to minimize the risk of delayed (defined as occurring the day after administration) systemic administration-related reactions [see Dosage and Administration (2.5)] .

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.

Local Reactions

In this pooled safety population, injection-site reactions occurred in 7% of patients, including Grade 2 reactions in 0.8%. The most frequent (>1%) injection-site reaction was injection site erythema. These local reactions occurred a median of 5 minutes (range: 0 minutes to 6.5 days) after starting administration of DARZALEX FASPRO. Monitor for local reactions and consider symptomatic management.

Cardiac Toxicity in Patients with Light Chain (AL) Amyloidosis

Serious or fatal cardiac adverse reactions occurred in patients with light chain (AL) amyloidosis who received DARZALEX FASPRO in combination with bortezomib, cyclophosphamide and dexamethasone [see Adverse Reactions (6.1)] . Serious cardiac disorders occurred in 16% and fatal cardiac disorders occurred in 10% of patients. Patients with NYHA Class IIIA or Mayo Stage IIIA disease may be at greater risk. Patients with NYHA Class IIIB or IV disease were not studied.

Monitor patients with cardiac involvement of light chain (AL) amyloidosis more frequently for cardiac adverse reactions and administer supportive care as appropriate.

Neutropenia

Daratumumab may increase neutropenia induced by background therapy [see Adverse Reactions (6.1)] .

Monitor complete blood cell counts periodically during treatment according to manufacturer's prescribing information for background therapies. Monitor patients with neutropenia for signs of infection. Consider withholding DARZALEX FASPRO until recovery of neutrophils. In lower body weight patients receiving DARZALEX FASPRO, higher rates of Grade 3–4 neutropenia were observed.

Thrombocytopenia

Daratumumab may increase thrombocytopenia induced by background therapy [see Adverse Reactions (6.1)] .

Monitor complete blood cell counts periodically during treatment according to manufacturer's prescribing information for background therapies. Consider withholding DARZALEX FASPRO until recovery of platelets.

Embryo-Fetal Toxicity

Based on the mechanism of action, DARZALEX FASPRO can cause fetal harm when administered to a pregnant woman. DARZALEX FASPRO may cause depletion of fetal immune cells and decreased bone density. Advise pregnant women of the potential risk to a fetus. Advise females with reproductive potential to use effective contraception during treatment with DARZALEX FASPRO and for 3 months after the last dose [see Use in Specific Populations (8.1, 8.3)] .

The combination of DARZALEX FASPRO with lenalidomide, thalidomide or pomalidomide is contraindicated in pregnant women, because lenalidomide, thalidomide or pomalidomide may cause birth defects and death of the unborn child. Refer to the lenalidomide, thalidomide or pomalidomide prescribing information on use during pregnancy.

Interference with Serological Testing

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 administration. Daratumumab bound to RBCs masks detection of antibodies to minor antigens in the patient's serum [see References (15)] . The determination of a patient's ABO and Rh blood type are not impacted [see Drug Interactions (7.1)] .

Notify blood transfusion centers of this interference with serological testing and inform blood banks that a patient has received DARZALEX FASPRO. Type and screen patients prior to starting DARZALEX FASPRO [see Dosage and Administration (2.1)] .

Interference with Determination of Complete Response

Daratumumab is a human IgG kappa monoclonal antibody that can be detected on both the serum protein electrophoresis (SPE) and immunofixation (IFE) assays used for the clinical monitoring of endogenous M-protein [see Drug Interactions (7.1)] . This interference can impact the determination of complete response and of disease progression in some DARZALEX FASPRO-treated patients with IgG kappa myeloma protein.

The following clinically significant adverse reactions are described elsewhere in the labeling:

Hypersensitivity and Other Administration Reactions [see Warnings and Precautions (5.1)] .
Cardiac Toxicity in Patients with Light Chain (AL) Amyloidosis [see Warnings and Precautions (5.2)] .
Neutropenia [see Warnings and Precautions (5.3)] .
Thrombocytopenia [see Warnings and Precautions (5.4)] .

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 [see Clinical Studies (14.1)] . 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, edema, pyrexia, upper respiratory infection, constipation, diarrhea, musculoskeletal pain, insomnia, and rash.

Table 7 summarizes the adverse reactions in patients who received DARZALEX FASPRO in PERSEUS.

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 [see References (15)] 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.

Daratumumab is an immunoglobulin G1 kappa (IgG1κ) human monoclonal antibody that binds to the CD38 antigen. Daratumumab is produced in Chinese Hamster Ovary (CHO) cells using recombinant DNA technology. The molecular weight of daratumumab is approximately 148 kDa.

Hyaluronidase (recombinant human) is an endoglycosidase used to increase the dispersion and absorption of co-administered drugs when administered subcutaneously. It is a glycosylated single-chain protein produced by Chinese Hamster Ovary cells containing a DNA plasmid encoding for a soluble fragment of human hyaluronidase (PH20). Hyaluronidase (recombinant human) has a molecular weight of approximately 61 kDa.

DARZALEX FASPRO ®(daratumumab and hyaluronidase-fihj) injection is a sterile, preservative-free, colorless to yellow, and clear to opalescent solution supplied in a single-dose vial for subcutaneous administration.

Each DARZALEX FASPRO 15 mL single-dose vial contains 1,800 mg of daratumumab and 30,000 units of hyaluronidase, L-histidine (4.9 mg), L-histidine hydrochloride monohydrate (18.4 mg), L-methionine (13.5 mg), polysorbate 20 (6 mg), sorbitol (735.1 mg), and Water for Injection, USP.

Mechanism of Action

CD38 is a transmembrane glycoprotein (48 kDa) expressed on the surface of hematopoietic cells, including clonal plasma cells in multiple myeloma and light chain (AL) amyloidosis, as well as other cell types. Surface CD38 has multiple functions, including receptor mediated adhesion, signaling, and modulation of cyclase and hydrolase activity. Daratumumab is an IgG1κ human monoclonal antibody (mAb) that binds to CD38 and inhibits the growth of CD38 expressing tumor cells by inducing apoptosis directly through Fc mediated cross linking as well as by immune-mediated tumor cell lysis through complement dependent cytotoxicity (CDC), antibody dependent cell mediated cytotoxicity (ADCC) and antibody dependent cellular phagocytosis (ADCP). A subset of myeloid derived suppressor cells (CD38+MDSCs), regulatory T cells (CD38+T regs) and B cells (CD38+B regs) are decreased by daratumumab.

Hyaluronan is a polysaccharide found in the extracellular matrix of the subcutaneous tissue. It is depolymerized by the naturally occurring enzyme hyaluronidase. Unlike the stable structural components of the interstitial matrix, hyaluronan has a half-life of approximately 0.5 days. Hyaluronidase increases permeability of the subcutaneous tissue by depolymerizing hyaluronan. In the doses administered, hyaluronidase in DARZALEX FASPRO acts locally. The effects of hyaluronidase are reversible and permeability of the subcutaneous tissue is restored within 24 to 48 hours.

Pharmacodynamics

NK cells express CD38 and are susceptible to daratumumab mediated cell lysis. Decreases in absolute counts and percentages of total NK cells (CD16+CD56+) and activated (CD16+CD56 dim) NK cells in peripheral whole blood and bone marrow were observed with DARZALEX FASPRO treatment.

Cardiac Electrophysiology

DARZALEX FASPRO as a large protein has a low likelihood of direct ion channel interactions. There is no evidence from non-clinical or clinical data to suggest that DARZALEX FASPRO has the potential to delay ventricular repolarization.

Exposure-Response Relationship

The exposure-response relationship and time course of pharmacodynamics of DARZALEX FASPRO have not been fully characterized.

Pharmacokinetics

Following the recommended dose of DARZALEX FASPRO 1,800 mg/30,000 units subcutaneously once weekly for 8 weeks, daratumumab peak concentration (C max) increased 4.8-fold and area under the curve (AUC 0–7 days) increased 5.4-fold from the 1 stdose to the 8 thdose as monotherapy. Maximum trough concentrations for DARZALEX FASPRO are typically observed at the end of the weekly dosing regimens for both monotherapy and combination therapies. The mean ± standard deviation (SD) maximum trough serum concentration (C trough) after the 8 thdose was 593 ± 306 µg/mL when DARZALEX FASPRO was administered as monotherapy and 537 ± 277 µg/mL, 526 ± 226 µg/mL, 756 ± 276 µg/mL, and 526 ± 209 µg/mL when DARZALEX FASPRO was administered as combination with Pd, Rd, Kd, and VRd, respectively.

Table 21 lists the observed mean (±SD) maximum trough concentrations (C trough) after the 8 thdose, simulated median (5 th–95 thpercentiles) maximum C troughafter the 8 thdose, simulated median (5 th–95 thpercentiles) C maxafter the 8 thdose, and simulated median (5 th–95 thpercentiles) area under the curve (AUC 0–7day) after the 8 thdose following DARZALEX FASPRO 1,800 mg/30,000 units administered subcutaneously or daratumumab 16 mg/kg administered intravenously in patients with multiple myeloma or light chain (AL) amyloidosis. Daratumumab exposures were similar between patients treated with DARZALEX FASPRO 1,800 mg/30,000 units monotherapy and combination therapies.

Absorption

At the recommended dose of DARZALEX FASPRO 1,800 mg/30,000 units, the absolute bioavailability is 69%, with peak concentrations occurring around 3 days (T max) in patients with multiple myeloma. Peak concentrations occurred around 4 days in patients with light chain (AL) amyloidosis.

Distribution

The estimated mean (coefficient of variation, CV) volume of distribution for the central compartment is 5.2 L (37%) and peripheral compartment was 3.8 L in patients with multiple myeloma. The estimated mean volume of distribution was 10.8 L (28%) in patients with light chain (AL) amyloidosis.

Elimination

Daratumumab is cleared by parallel linear and nonlinear saturable target mediated clearances. The estimated mean (CV%) linear clearance of daratumumab is 119 mL/day (59%) in patients with multiple myeloma and is 210 mL/day (42%) in patients with light chain (AL) amyloidosis. The estimated mean (CV%) elimination half-life associated with linear clearance is 20 days (22%) in patients with multiple myeloma and 28 days (74%) in patients with light chain (AL) amyloidosis.

Specific Populations

The following population characteristics have no clinically meaningful effect on the pharmacokinetics of daratumumab in patients administered DARZALEX FASPRO as monotherapy or as combination therapy: sex, age (33 to 92 years), renal impairment [Creatinine clearance (CLcr) 15 to 89 mL/min as determined by the Cockcroft-Gault formula], and mild hepatic impairment (total bilirubin 1 to 1.5 times ULN and AST>ULN). The effect of moderate and severe hepatic impairment on daratumumab pharmacokinetics is unknown.

Racial or Ethnic Groups

Of 190 patients with light chain (AL) amyloidosis who received DARZALEX FASPRO and had a maximum C troughafter the 8 thdose, African-Americans (4%) had 24% higher daratumumab mean maximum C troughafter the 8 thdose compared to that of Whites (83%) and Asians (10%) had 16% higher mean maximum C troughafter the 8 thdose compared to that of Whites. The difference in exposure between that of Asians and Whites could be explained in part by differences in body size. The effect of African-American race on exposure and related safety and efficacy of daratumumab is unknown.

Body Weight

In patients with multiple myeloma who received DARZALEX FASPRO 1,800 mg/30,000 units as monotherapy, the mean maximum C troughafter the 8 thdose was 12% lower in the higher body weight (BW) group (>85 kg), while the mean maximum C troughafter the 8 thdose was 81% higher in the lower BW group (≤50 kg) compared to the corresponding BW groups in the intravenous daratumumab arm.

In patients with light chain (AL) amyloidosis who received DARZALEX FASPRO 1,800 mg/30,000 units in combination and had a maximum C troughafter the 8 thdose, the mean maximum C troughafter the 8 thdose was 22% lower in the higher BW group (>85 kg), while the mean maximum C troughwas 37% higher in the lower BW group (≤50 kg) compared to the patients with body weight of 51–85 kg.

Immunogenicity

The observed incidence of anti-drug antibody (ADA, including neutralizing antibody) is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of ADA in the studies described below with the incidence of ADA in other studies, including those of daratumumab or of other daratumumab products.

With the median DARZALEX FASPRO treatment ranging from 6.5 to 35.9 months across 7 clinical trials of patients with multiple myeloma and light chain (AL) amyloidosis treated with DARZALEX as monotherapy or as combination therapies, the incidence of anti-daratumumab antibody development was 0.6% (7/1,200) and 6 patients tested positive for neutralizing antibodies. Because of the low occurrence of anti-daratumumab antibodies, the effect of these antibodies on the pharmacokinetics, pharmacodynamics, safety, and/or effectiveness of daratumumab products is unknown.

With the median DARZALEX FASPRO treatment ranging from 6.5 to 35.9 months across 7 clinical trials of patients with multiple myeloma and light chain (AL) amyloidosis treated with DARZALEX as monotherapy or as combination therapies, the incidence of anti-rHuPH20 antibody development was 8.9% (106/1,193) and 1 patient tested positive for neutralizing antibodies. There was no identified clinically significant effect of anti-rHuPH20 antibodies on pharmacokinetics, pharmacodynamics, safety, or effectiveness of daratumumab products.

Carcinogenesis, Mutagenesis, Impairment of Fertility

No carcinogenicity or genotoxicity studies have been conducted with daratumumab. No animal studies have been performed to evaluate the potential effects of daratumumab on reproduction or development, or to determine potential effects on fertility in males or females.

No carcinogenicity, genotoxicity, or fertility studies were conducted for recombinant human hyaluronidase. There were no effects on reproductive tissues and function and no systemic exposure of hyaluronidase in monkeys given 22,000 U/kg/week subcutaneously (12 times higher than the human dose) for 39 weeks. As hyaluronidase is a recombinant form of the endogenous human hyaluronidase, no carcinogenicity, mutagenesis, or effects on fertility are expected.

Newly Diagnosed Multiple Myeloma

In Combination with Bortezomib, Lenalidomide and Dexamethasone in Patients Eligible for Autologous Stem Cell Transplant

The efficacy of DARZALEX FASPRO with bortezomib, lenalidomide and dexamethasone (DARZALEX FASPRO-VRd) during induction and consolidation was evaluated in PERSEUS (NCT03710603), an open-label, randomized, active-controlled trial in patients with newly diagnosed multiple myeloma eligible for ASCT. Enrollment was limited to patients 70 years of age and younger.

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. 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. Bortezomib was administered by subcutaneous injection at a dose of 1.3 mg/m 2body surface area twice weekly for two weeks (days 1, 4, 8, and 11) of each 28-day cycle for weeks 1–16 during induction and weeks 1–8 during consolidation. Lenalidomide was administered orally at 25 mg daily (days 1–21) during weeks 1–16 during induction and weeks 1–8 during consolidation. Dexamethasone (oral or intravenous) was administered at 40 mg on Days 1–4 and Days 9–12 during weeks 1–16 during induction and weeks 1–8 during consolidation. On the days of DARZALEX FASPRO injection, the dexamethasone dose was administered orally or intravenously as a pre-injection medication. Following consolidation, patients received an investigational treatment regimen for maintenance that included DARZALEX FASPRO in combination with lenalidomide or lenalidomide alone. The trial was not designed to isolate the effect of DARZALEX FASPRO in the maintenance phase of treatment. The efficacy of DARZALEX FASPRO in combination with lenalidomide for maintenance has not been established.

The major efficacy outcome measure was progression-free survival (PFS) by independent review committee (IRC) based on IMWG response criteria.

A total of 709 patients were randomized: 355 to the DARZALEX FASPRO-VRd arm and 354 to the VRd arm. The median age was 60 years (range: 31 to 70); 59% were male, 92% were White, 1% were Black or African American, and 1% were Asian. Fifty-one percent had ISS Stage I, 34% had ISS Stage II, 15% had ISS Stage III disease. High-risk cytogenetics (presence of del(17p), t(4;14), t(14,16)) were present in 22% of patients.

PERSEUS demonstrated an improvement in PFS in the DARZALEX FASPRO-VRd arm as compared to the VRd arm; the median PFS had not been reached in either arm. Treatment with DARZALEX FASPRO-VRd resulted in a reduction in the risk of disease progression or death by 60% compared to VRd alone (HR [95% CI]: 0.40 [0.29, 0.57]; p-value < 0.0001).

In Combination with Bortezomib, Melphalan and Prednisone in Patients Ineligible for Autologous Stem Cell Transplant

The efficacy of DARZALEX FASPRO with bortezomib, melphalan and prednisone was evaluated in a single-arm cohort of PLEIADES (NCT03412565), a multi-cohort, open-label trial. Eligible patients were required to have newly diagnosed multiple myeloma who are ineligible for transplant. Patients received DARZALEX FASPRO 1,800 mg/30,000 units administered subcutaneously once weekly from weeks 1 to 6, once every 3 weeks from weeks 7 to 54 and once every 4 weeks starting with week 55 until disease progression or unacceptable toxicity; bortezomib 1.3 mg/m 2subcutaneously twice weekly on Weeks 1, 2, 4 and 5 for the first 6-week cycle (Cycle 1; 8 doses), followed by once weekly on Weeks 1, 2, 4 and 5 for eight more 6-week cycles (Cycles 2–9; 4 doses per cycle); and melphalan 9 mg/m 2and prednisone 60 mg/m 2orally on Days 1 to 4 of the nine 6-week cycles (Cycles 1–9). The major efficacy outcome measure was overall response rate (ORR).

A total of 67 patients received DARZALEX FASPRO with VMP. The median age was 75 years (range: 66 to 86 years); 46% were male; 69% were White, 8% Asian, and 2% Black or African American; and 33% had ISS Stage I, 45% had ISS Stage II, and 22% had ISS Stage III disease.

Efficacy results are summarized in Table 23. The median duration of follow-up for patients was 6.9 months.

Relapsed/Refractory Multiple Myeloma

In Combination with Lenalidomide and Dexamethasone

The efficacy of DARZALEX FASPRO with lenalidomide and dexamethasone (DARZALEX FASPRO-Rd) was evaluated in a single-arm cohort of PLEIADES (NCT03412565), a multi-cohort, open-label trial. Patients received DARZALEX FASPRO 1,800 mg/30,000 units administered subcutaneously once weekly from weeks 1 to 8, once every 2 weeks from weeks 9 to 24 and once every 4 weeks starting with week 25 until disease progression or unacceptable toxicity with lenalidomide 25 mg once daily orally on Days 1–21 of each 28-day cycle; and dexamethasone 40 mg per week (or a reduced dose of 20 mg per week for patients >75 years or BMI <18.5). The major efficacy outcome measure was ORR.

A total of 65 patients received DARZALEX FASPRO with Rd. The median age was 69 years (range: 33 to 82 years); 69% were male; 69% were White, and 3% Black or African American; and 42% had ISS Stage I, 30% had ISS Stage II, and 28% had ISS Stage III disease. Patients had received a median of 1 prior line of therapy. A total of 52% of patients had a prior ASCT; 95% of patients received a prior PI; 59% received a prior immunomodulatory agent, including 22% who received prior lenalidomide; and 54% of patients received both a prior PI and immunomodulatory agent.

Efficacy results are summarized in Table 24. The median duration of follow-up for patients was 7.1 months.

In Combination with Pomalidomide and Dexamethasone

The efficacy of DARZALEX FASPRO with pomalidomide and dexamethasone (DARZALEX FASPRO-Pd) versus pomalidomide and dexamethasone (Pd) alone was evaluated in APOLLO (NCT03180736), an open-label, randomized, active-controlled trial. Patients received DARZALEX FASPRO 1,800 mg/30,000 units administered subcutaneously once weekly from weeks 1 to 8, once every 2 weeks from weeks 9 to 24 and once every 4 weeks starting with week 25 until disease progression or unacceptable toxicity with pomalidomide 4 mg once daily orally on Days 1–21 of each 28-day cycle; and dexamethasone 40 mg per week (or a reduced dose of 20 mg per week for patients >75 years). The major efficacy outcome measure was progression-free survival (PFS).

A total of 304 patients were randomized: 151 to the DARZALEX FASPRO-Pd arm and 153 to the Pd arm. The median age was 67 years (range: 35 to 90); 53% were male and 89% were White, <1% were Black or African American, and <1% were Asian, and 45% had ISS Stage I, 33% had ISS Stage II, and 22% had ISS Stage III disease. Patients had received a median of 2 prior lines of therapy (range 1–5), with 11% of patients having received 1 prior line of therapy and 75% of patients having received 2–3 prior lines of therapy. All patients received a prior treatment with a PI and lenalidomide, and 56% of patients received prior ASCT. The majority of patients were refractory to lenalidomide (80%), a PI (48%), or both an immunomodulatory agent and a PI (42%).

APOLLO demonstrated an improvement in PFS in the DARZALEX FASPRO-Pd treatment group as compared to the Pd treatment group; the median PFS was 12.4 months in the DARZALEX FASPRO-Pd treatment group and 6.9 months in the Pd treatment group (HR [95% CI]: 0.63 [0.47, 0.85]; p-value = 0.0018), representing a 37% reduction in the risk of disease progression or death for patients treated with DARZALEX FASPRO-Pd versus Pd.

In responders, the median time to response was 1 month (range: 0.9 to 9.1 months) in the DARZALEX FASPRO-Pd group and 1.9 months (range: 0.9 to 17.3 months) in the Pd group. The median duration of response had not been reached in the DARZALEX FASPRO-Pd group (range: 1 to 34.9+ months) and was 15.9 months (range: 1+ to 24.8 months) in the Pd group.

With a median follow-up of 16.9 months, 99 deaths were observed; 48 in the DARZALEX FASPRO-Pd group and 51 in the Pd group. Median OS was not reached for either treatment group.

In Combination with Carfilzomib and Dexamethasone

The efficacy of DARZALEX FASPRO with carfilzomib and dexamethasone (DARZALEX FASPRO-Kd) was evaluated in a single-arm cohort of PLEIADES (NCT03412565), a multi-cohort, open-label trial. This cohort enrolled patients with relapsed or refractory multiple myeloma excluding patients with left ventricular ejection fraction (LVEF) less than 40%, myocardial infarction within 6 months, uncontrolled cardiac arrhythmia, or uncontrolled hypertension (systolic blood pressure >159 mmHg or diastolic >99 mmHg despite optimal treatment). Patients received DARZALEX FASPRO 1,800 mg/30,000 units administered subcutaneously once weekly from Weeks 1 to 8, once every 2 weeks from Weeks 9 to 24 and once every 4 weeks starting with Week 25 until disease progression or unacceptable toxicity with carfilzomib administered by IV infusion at a dose of 20 mg/m 2on Cycle 1 Day 1 and if a dose of 20 mg/m 2was tolerated, carfilzomib was administered at a dose of 70 mg/m 2as a 30-minute IV infusion, on Cycle 1 Day 8 and Day 15, and then Day 1, 8 and 15 of each cycle and dexamethasone 40 mg per week (or a reduced dose of 20 mg per week for patients ≥75 years or BMI <18.5). The major efficacy outcome measure was ORR.

A total of 66 patients received DARZALEX FASPRO with Kd. The median age was 61 years (range: 42 to 84); 52% were male; 73% were White and 3% Black or African American; and 68% had ISS Stage I, 18% had ISS Stage II, and 14% had ISS Stage III disease. A total of 79% of patients had a prior ASCT; 91% of patients received a prior PI. All patients received 1 prior line of therapy with exposure to lenalidomide and 62% of patients were refractory to lenalidomide.

Efficacy results are summarized in Table 26. At a median follow-up of 9.2 months, the median duration of response had not been reached and an estimated 85.2% (95% CI: 72.5, 92.3) maintained response for at least 6 months and 82.5% (95% CI: 68.9, 90.6) maintained response for at least 9 months.

Monotherapy

The efficacy of DARZALEX FASPRO as monotherapy was evaluated in COLUMBA (NCT03277105), an open-label, randomized, non-inferiority study. Eligible patients were required to have relapsed or refractory multiple myeloma who had received at least 3 prior lines of therapy including a proteasome inhibitor and an immunomodulatory agent or who were double-refractory to a proteasome inhibitor and an immunomodulatory agent. Patients were randomized to receive DARZALEX FASPRO 1,800 mg/30,000 units administered subcutaneously or daratumumab 16 mg/kg administered intravenously; each administered once weekly from weeks 1 to 8, once every 2 weeks from weeks 9 to 24 and once every 4 weeks starting with week 25 until unacceptable toxicity or disease progression. The major efficacy outcome measures were ORR by the IMWG response criteria and maximum C troughat pre-dose Cycle 3 Day 1 [see Clinical Pharmacology (12.3)] . Randomization was stratified by body weight, myeloma type, and number of prior lines of therapy.

A total of 522 patients were randomized: 263 to the DARZALEX FASPRO arm and 259 to the intravenous daratumumab arm. The median age was 67 years (range: 33 to 92 years); 55% were male; and 78% were White, 14% Asian, and 3% Black or African American. The median weight was 73 kg (range: 29 to 138). Patients had received a median of 4 prior lines of therapy. A total of 51% of patients had a prior ASCT; 100% of patients received both a PI and an immunomodulatory agent. Forty-nine percent of patients were refractory both a PI and an immunomodulatory agent. Eighty-two percent of patients were refractory to their last line of prior systemic therapy.

The results show that DARZALEX FASPRO 1,800 mg/30,000 units administered subcutaneously is non-inferior to daratumumab 16 mg/kg administered intravenously in terms of ORR and maximum trough concentration [see Clinical Pharmacology (12.3)] . Median progression-free survival was 5.6 months in the DARZALEX FASPRO arm and 6.1 months in the intravenous daratumumab arm. ORR results are provided in Table 27.

Light Chain Amyloidosis

In Combination with Bortezomib, Cyclophosphamide and Dexamethasone

The efficacy of DARZALEX FASPRO with VCd was evaluated in ANDROMEDA (NCT03201965), an open-label, randomized, active-controlled trial. Eligible patients were required to have newly diagnosed light chain (AL) amyloidosis with at least one affected organ, measurable hematologic disease, Cardiac Stage I-IIIA (based on European Modification of Mayo 2004 Cardiac Stage), and NYHA Class I-IIIA. Patients with NYHA Class IIIB and IV were excluded. Patients were randomized to receive bortezomib 1.3 mg/m 2administered subcutaneously, cyclophosphamide 300 mg/m 2(max dose 500 mg) administered orally or intravenously, and dexamethasone 40 mg (or a reduced dose of 20 mg for patients >70 years or body mass index <18.5 or who have hypervolemia, poorly controlled diabetes mellitus or prior intolerance to steroid therapy) administered orally or intravenously on Days 1, 8, 15, and 22 of each 28-day cycle with or without DARZALEX FASPRO 1,800 mg/30,000 units subcutaneously once weekly from weeks 1 to 8, once every 2 weeks from weeks 9 to 24 and once every 4 weeks starting with week 25 until disease progression or a maximum of two years. When DARZALEX FASPRO and dexamethasone were administered on the same day, dexamethasone 20 mg was administered before DARZALEX FASPRO with the remaining dose of dexamethasone administered after DARZALEX FASPRO if applicable. The major efficacy outcome measure was confirmed hematologic complete response (HemCR) rate based on Consensus Criteria as determined by the Independent Review Committee (negative serum and urine immunofixation, involved free light chain level decrease to less than the upper limit of normal, and normal free light chain ratio). Randomization was stratified by Cardiac Stage (European Modification of Mayo 2004 Cardiac Stage) countries that typically offer autologous stem cell transplant (ASCT) for patients with light chain (AL) amyloidosis, and renal function.

A total of 388 patients were randomized: 195 to DARZALEX FASPRO-VCd and 193 to VCd. The median patient age was 64 years (range: 34 to 87 years); 58% were male; 76% White, 17% Asian, and 3% Black or African American; 23% had light chain (AL) amyloidosis Cardiac Stage I, 40% had Stage II, and 37% had Stage IIIA. The median number of organs involved was 2 (range: 1–6) and 66% of patients had 2 or more organs involved. Vital organ involvement was: cardiac 71%, renal 59% and hepatic 8%. The majority (79%) of patients had lambda free light chain disease.

Efficacy results are summarized in Table 28.

The median time to HemCR was 59 days (range: 8 to 299 days) in the DARZALEX FASPRO-VCd arm and 59 days (range: 16 to 340 days) in the VCd arm. The median time to VGPR or better was 17 days (range: 5 to 336 days) in the DARZALEX FASPRO-VCd arm and 25 days (range: 8 to 171 days) in the VCd arm. The median duration of HemCR had not been reached in either arm.

The median follow-up for the study is 11.4 months. Overall survival (OS) data were not mature. A total of 56 deaths were observed [N=27 (13.8%) DARZALEX FASPRO-VCd vs. N=29 (15%) VCd group].
