Consumer medicine information (CMI) leaflet

Please read this leaflet carefully before you start using Darzalex.

What is in this leaflet

This leaflet answers some common questions about DARZALEX Concentrate for Solution for Infusion. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you being given DARZALEX against the benefits this medicine is expected to have for you.

If you have any concerns about being given DARZALEX ask your doctor.

Keep this leaflet while you are being treated with DARZALEX. You may need to read it again.

What DARZALEX is used for

DARZALEX is an anti-cancer medicine and contains the active substance daratumumab. This belongs to a group of medicines called "monoclonal antibodies". One of the ways monoclonal antibodies work is by attaching themselves to specific cancer cells in your body, so your immune system can destroy them.

DARZALEX is used to treat adults with multiple myeloma (cancer of the bone marrow).

Your doctor may have prescribed DARZALEX for another reason.

Ask your doctor if you have any questions about why DARZALEX has been prescribed for you.

This medicine is available only with a doctor's prescription.

Before you are given DARZALEX

When you must not use it:

Do not use DARZALEX if:

  • you know you are allergic (hypersensitive) to daratumumab or other ingredients of DARZALEX. See Product Description at the end of this leaflet for a list of ingredients.

Symptoms of an allergic reaction may include rash, itching or hives on the skin, shortness of breath, wheezing or difficulty breathing, swelling of the face, lips, tongue or other parts of the body.

DARZALEX should not be given to children or young people below 18 years of age. This is because it is not known how the medicine will affect them.

Before you start to use it:

Tell your doctor if you have or have had any medical conditions, especially the following:

  • blood disorder with a low level of white blood cells or platelets. This disorder may become worse during treatment with DARZALEX.
  • Hepatitis B infection
    DARZALEX could cause hepatitis B virus to become active again. Your doctor will check you for signs of this infection before, during and for some time after treatment with DARZALEX.

Tell your doctor if you are pregnant or intend to become pregnant. Like most medicines used to treat cancer, DARZALEX is not recommended for use during pregnancy.

Tell your doctor if you are trying to make your partner pregnant.

Both men and women receiving DARZALEX and their partners must use a reliable method of contraception during and for 3 months after ceasing treatment with DARZALEX.

Tell your doctor if you are breastfeeding or intend to breastfeed. It is not known whether DARZALEX passes into breast milk. Therefore there is a possibility that the breastfed baby may be affected.

If you wish to restart breastfeeding after your DARZALEX treatment, you must discuss this with your doctor or nurse, who will tell you when it is safe to do so.

If you have not told your doctor about any of the above, tell them before you start treatment with DARZALEX.

Taking other medicines:

Tell your doctor if you are taking any other medicines, including vitamins and herbal supplements and including medicines you can buy with or without a prescription from a pharmacy, supermarket or health food shop.

These medicines may be affected by DARZALEX or may affect how well DARZALEX works. Your doctor or pharmacist can tell you what to do if you are using any other medicines.

How DARZALEX is given

How much is given:

Your doctor will work out your dose and schedule of DARZALEX. The dose of DARZALEX will depend on your body weight. The usual starting dose of DARZALEX is 16 mg per kg of body weight.

DARZALEX may be given alone or together with other medicines used to treat multiple myeloma.

Ask your doctor if you want to know more about the dose of DARZALEX you receive.

How it is given:

DARZALEX will be given to you by a doctor or nurse.

DARZALEX will be diluted in sterile normal sodium chloride (salt) solution for injection.

It is given over several hours as a drip into a vein ("intravenous infusion").

When it is given:

Your doctor will tell you when DARZALEX will be given. The frequency depends on whether it is given alone or together with other medicines used to treat multiple myeloma.

Medicines given during treatment with DARZALEX:

DARZALEX may be given alone or together with other medicines used to treat multiple myeloma (with bortezomib, thalidomide and dexamethasone, or with bortezomib, melphalan and prednisone, or with lenalidomide and dexamethasone or with bortezomib and dexamethasone).

Read the Consumer Medicine Information for all medicines you take in combination with DARZALEX.

You may be given medicines to lower the chance of getting shingles.

Before each infusion of DARZALEX you will be given medicines which help to lower the chance of infusion-related reactions. These may include:

  • medicines for an allergic reaction (anti-histamines)
  • medicines for inflammation (corticosteroids)
  • medicines for fever (such as paracetamol).

After each infusion of DARZALEX you will be given medicines by mouth (such as corticosteroids) to lower the chance of infusion-related reactions.

People with breathing problems:

If you have breathing problems, such as asthma or Chronic Obstructive Pulmonary Disease (COPD), you may be given medicines to inhale which help your breathing problems:

  • medicines to help the airways in your lungs stay open (bronchodilators)
  • medicines to lower swelling and irritation in your lungs (corticosteroids)

What do I do if I receive too much? (overdose):

This medicine will be given by your doctor or nurse. In the unlikely event that you are given too much (an overdose) your doctor will check you for side effects.

If you forget your appointment to have DARZALEX:

It is very important to go to all your appointments to make sure your treatment works. If you miss an appointment, make another one as soon as possible.

If you have any further questions on the use of this medicine, ask your doctor or nurse.

While you are using DARZALEX

Things you must do:

Be sure to keep all your doctor's appointments so your progress can be checked. Your doctor will want to do some blood, urine and other tests from time to time to check on your progress and detect any unwanted side effects.

Keep follow up appointments with your doctor. It is important to have your follow-up doses of DARZALEX at the appropriate times to get the best effects from your treatment.

Be sure to follow your doctor's instructions about other medicines you should take, and other things you should do.

Tell any other doctors, dentists and pharmacists who are treating you that you are having DARZALEX.

If you are about to be started on any new medicines, tell your doctor, dentist or pharmacist that you are having DARZALEX.

If you become pregnant or your partner becomes pregnant while being given DARZALEX, tell your doctor immediately.

If you need to have a blood test, tell the person doing the test that you are using DARZALEX.

Decreased blood cell counts

DARZALEX can decrease white blood cell counts which help fight infections, and blood cells called platelets which help to clot blood.

Tell your doctor if you develop fever or if you have signs of bruising or bleeding.

The following precautions should be taken to reduce your risk of infection or bleeding:

  • Avoid people who have infections. Check with your doctor immediately if you think you may be getting an infection, or if you get a fever, chills, cough, hoarse throat, lower back or side pain or find it is painful or difficult to urinate.
  • Be careful when using a toothbrush, toothpick or dental floss. Your doctor, dentist, nurse or pharmacist may recommend other ways to clean your teeth and gums. Check with your doctor before having any dental work.
  • Be careful not to cut yourself when you are using sharp objects such as a razor or nail cutters.

Blood transfusions

If you need a blood transfusion, you will have a blood test first to match your blood type. DARZALEX can affect the results of this blood test. Tell the person doing the test that you are using DARZALEX.

Hepatitis B

If you have ever had a hepatitis B infection, DARZALEX could cause hepatitis B virus to become active again. Your doctor will check you for signs of this infection before, during and for some time after treatment with DARZALEX.

Tell your doctor right away if you get increasingly tired or get yellowing of your skin or white part of your eyes.

Infusion-related reactions

Before and after each infusion of DARZALEX, you will be given medicines which help to lower the chance of infusion-related reactions (see “Medicines given during treatment with DARZALEX”). Some serious allergic reactions and other severe infusion related reactions have resulted in death. These reactions can happen during the infusion or in the 3 days after the infusion.

Tell your doctor or nurse right away if you get any of the infusion-related reactions listed at the top of the Side Effects section.

If you get infusion-related reactions, you may need other medicines, or the infusion may need to be slowed down or stopped. When these reactions go away, or get better the infusion can be started again.

These reactions are most likely to happen with the first infusion. If you have had an infusion-related reaction once it is less likely to happen again. Your doctor may decide not to continue DARZALEX if you have a strong infusion-related reaction.

Things to be careful of

Be careful driving or operating machinery until you know how DARZALEX affects you. DARZALEX may cause tiredness and other effects in some people. Make sure you know how you react to DARZALEX before you drive a car, operate machinery, or do anything else that could be dangerous if you have side effects.

Side Effects

Like all medicines, DARZALEX can cause side effects, although not everybody gets them. Some of these effects may be serious. However, there may be ways to reduce the discomfort of these effects. You may need medical treatment if you get some of the side effects.

Tell your doctor, nurse or pharmacist as soon as possible if you do not feel well while you are being treated with DARZALEX.

Do not be alarmed by the following lists of side effects. You may not experience any of them.

Ask your doctor or pharmacist to answer any questions you may have.

Below is a list of the more common side effects that you could get while being treated with DARZALEX:

- Infusion-related reactions

Recommended concomitant medications.

Pre-infusion medication.

It is important to administer the following pre-infusion medications to reduce the risk of IRRs (including fatal IRRs) to all patients 1-3 hours prior to every infusion of Darzalex:
Corticosteroid (long-acting or intermediate-acting). Monotherapy: Methylprednisolone 100 mg, or equivalent, administered intravenously. Following the second infusion, the dose of corticosteroid may be reduced (oral or intravenous methylprednisolone 60 mg).
Combination therapy: Administer 20 mg dexamethasone (or equivalent) prior to every Darzalex infusion.
When dexamethasone is the background-regimen specific corticosteroid, the dexamethasone treatment dose will instead serve as pre-medication on Darzalex infusion days (see Section 5.1 Pharmacodynamic Properties, Clinical trials).
Dexamethasone is given intravenously prior to the first Darzalex infusion and oral administration may be considered prior to subsequent infusions. Additional background regimen specific corticosteroids (e.g. prednisone) should not be taken on Darzalex infusion days when patients have received dexamethasone as a pre-medication.
Antipyretics (oral paracetamol 500 to 1000 mg).
Antihistamine (oral or intravenous diphenhydramine 25 to 50 mg or equivalent).

Post-infusion medication.

Administer post-infusion medication to reduce the risk of delayed infusion related reactions as follows:
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 infusions (beginning the day after the infusion).
Combination therapy: Consider administering low-dose oral methylprednisolone (≤ 20 mg) or equivalent the day after the Darzalex infusion.
However, if a background regimen-specific corticosteroid (e.g. dexamethasone, prednisone) is administered the day after the Darzalex infusion, additional post-infusion medications may not be needed (see Section 5.1 Pharmacodynamic Properties, Clinical trials).
Additionally, for patients with a history of chronic obstructive pulmonary disease, consider the use of post-infusion medications including short and long acting bronchodilators, and inhaled corticosteroids. Following the first four infusions, if the patient experiences no major IRRs, these inhaled post-infusion medications may be discontinued at the discretion of the physician.

Prophylaxis for herpes zoster virus reactivation.

Anti-viral prophylaxis should be considered for the prevention of herpes zoster virus reactivation.

Management of infusion-related reactions.

It is important to administer pre-infusion medications to reduce the risk of IRRs (including fatal IRRs) prior to treatment with Darzalex.
For IRRs of any grade/severity, immediately interrupt the Darzalex infusion and manage symptoms.
Management of IRRs may further require reduction in the rate of infusion, or treatment discontinuation of Darzalex as outlined below (also see Section 4.4 Special Warnings and Precautions for Use).

Grade 1-2 (mild to moderate).

Once reaction symptoms resolve, resume the infusion at no more than half the rate at which the IRR occurred. If the patient does not experience any further IRR symptoms, infusion rate escalation may resume at increments and intervals as clinically appropriate up to the maximum rate of 200 mL/hour (see Administration, Table 5).

Grade 3 (severe).

Once reaction symptoms resolve, consider restarting the infusion at no more than half the rate at which the reaction occurred. If the patient does not experience additional symptoms, resume infusion rate escalation at increments and intervals as appropriate (see Administration, Table 5). Repeat the procedure above in the event of recurrence of Grade 3 symptoms. Permanently discontinue Darzalex upon the third occurrence of a Grade 3 or greater infusion reaction.

Grade 4 (life threatening).

Permanently discontinue Darzalex treatment.

Missed dose(s).

If a planned dose of Darzalex is missed, administer the dose as soon as possible and adjust the dosing schedule accordingly, maintaining the treatment interval.

Dose modifications.

No dose reductions of Darzalex are recommended. Dose delay may be required to allow recovery of blood cell counts in the event of haematological toxicity (see Section 4.4 Special Warnings and Precautions for Use). For information concerning medicinal products given in combination with Darzalex, see manufacturer's Product Information.

Special populations.

Paediatrics (17 years of age and younger).

The safety and efficacy of Darzalex have not been established in paediatric patients.

Elderly (65 years of age and older).

No dose adjustments are considered necessary in elderly patients (see Section 5.2 Pharmacokinetic Properties; Section 4.8 Adverse Effects (Undesirable Effects)).

Renal impairment.

No formal studies of daratumumab in patients with renal impairment have been conducted.
Based on population pharmacokinetic (PK) analyses, no dosage adjustment is necessary for patients with renal impairment (see Section 5.2 Pharmacokinetic Properties).

Hepatic impairment.

No formal studies of daratumumab in patients with hepatic impairment have been conducted. Changes in hepatic function are unlikely to have any effect on the elimination of daratumumab since IgG1 molecules such as daratumumab are not metabolised through hepatic pathways. Based on population PK analyses, no dosage adjustments are necessary for patients with hepatic impairment) (see Section 5.2 Pharmacokinetic Properties).

Administration.

Darzalex is administered as an intravenous infusion following dilution with 0.9% Sodium Chloride. For instructions on dilution of the medicinal product before administration, see Instructions for use and handling; see Section 6.6 Special Precautions for Disposal.
Following dilution, the Darzalex infusion should be intravenously administered at the appropriate initial infusion rate presented in Table 5. Incremental escalation of the infusion rate should be considered only in the absence of infusion reactions.
To facilitate administration, the first prescribed 16 mg/kg dose at Week 1 may be split over two consecutive days i.e. 8 mg/kg on Day 1 and Day 2 respectively, see Table 5.

Instructions for use and handling.

Prepare the solution for infusion using aseptic technique as follows:
Calculate the dose (mg), total volume (mL) of Darzalex solution required and the number of Darzalex vials needed based on patient weight.
Check that the Darzalex solution is colourless to yellow. Do not use if opaque particles, discoloration or other foreign particles are present.
Using aseptic technique, remove a volume of 0.9% Sodium Chloride from the infusion bag/container that is equal to the required volume of Darzalex solution.
Withdraw the necessary amount of Darzalex solution and dilute to the appropriate volume by adding to an infusion bag/container containing 0.9% Sodium Chloride (see Administration). Infusion bags/containers must be made of polyvinylchloride (PVC), polypropylene (PP), polyethylene (PE) or polyolefin blend (PP+PE). Dilute under appropriate aseptic conditions. Discard any unused portion left in the vial.
Gently invert the bag/container to mix the solution. Do not shake or freeze.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. The diluted solution may develop very small, translucent to white proteinaceous particles, as daratumumab is a protein. Do not use if visibly opaque particles, discoloration or foreign particles are observed.
Since Darzalex does not contain a preservative, diluted solutions should be administered within 15 hours (including infusion time) at room temperature 15°C-25°C and in room light.
If not used immediately, the diluted solution can be stored prior to administration for up to 24 hours at refrigerated conditions 2°C - 8°C and protected from light. Do not freeze.
Administer the diluted solution by intravenous infusion using an infusion set fitted with a flow regulator and with an in-line, sterile, non-pyrogenic, low protein-binding polyethersulfone (PES) filter (pore size 0.22 or 0.2 micrometre). Polyurethane (PU), polybutadiene (PBD), PVC, PP or PE administration sets must be used.
Do not infuse Darzalex concomitantly in the same intravenous line with other agents.

Do not store any unused portion of the infusion solution for reuse.

4.3 Contraindications

Patients with a history of severe hypersensitivity (e.g. anaphylactic reaction) to daratumumab, or to any of the excipients.
Before starting therapy, refer to the Product Information for medicinal products used in combination with Darzalex.

4.4 Special Warnings and Precautions for Use

Before starting combination therapy, also refer to the Product Information for relevant other medicines (bortezomib, lenalidomide, thalidomide, dexamethasone, as appropriate).
Patients receiving Darzalex in combination with lenalidomide and dexamethasone or thalidomide and dexamethasone should adhere to the pregnancy prevention programmes of lenalidomide or thalidomide (see Section 4.6 Fertility, Pregnancy and Lactation).

Infusion-related reactions.

Darzalex can cause serious IRRs, including anaphylactic reactions. These reactions can be life-threatening and fatal outcomes have been reported.
Monitor patients throughout the infusion and the post-infusion period.
In clinical trials, IRRs were reported in approximately half of all patients treated with Darzalex.
The majority of IRRs occurred at the first infusion and were Grade 1-2. Four percent of patients had an IRR at more than one infusion. Severe reactions have occurred, including bronchospasm, hypoxia, dyspnoea, hypertension, laryngeal oedema, pulmonary oedema, myocardial infarction, and ocular adverse reactions (including choroidal effusion, acute myopia and acute angle closure glaucoma). Signs and symptoms may include respiratory symptoms, such as nasal congestion, cough, throat irritation, as well as chills, vomiting and nausea. Less common symptoms were wheezing, allergic rhinitis, pyrexia, chest discomfort, pruritus, hypotension, and blurred vision (see Section 4.8 Adverse Effects (Undesirable Effects)). Fatal IRRs were not reported in these trials.
Pre-medicate patients with antihistamines, antipyretics and corticosteroids to reduce the risk of IRRs (including fatal IRRs) prior to treatment with Darzalex (see Section 4.2 Dose and Method of Administration). Interrupt Darzalex infusion for IRRs of any severity and institute medical management/supportive treatment as needed. For patients with Grade 1, 2, or 3 reactions, reduce the infusion rate when re-starting the infusion. If an anaphylactic reaction or life threatening (Grade 4) IRR occurs, permanently discontinue administration of Darzalex and institute appropriate emergency care (see Section 4.2 Dose and Method of Administration).
To reduce the risk of delayed IRRs, administer oral corticosteroids to all patients following all Darzalex infusions. Additionally consider the use of post-infusion medications (e.g. inhaled corticosteroids, short and long acting bronchodilators) for patients with a history of chronic obstructive pulmonary disease to manage respiratory complications should they occur. If ocular symptoms occur, interrupt Darzalex infusion and seek immediate ophthalmologic evaluation prior to restarting Darzalex (see Section 4.2 Dose and Method of Administration).

Neutropenia/thrombocytopenia.

Darzalex increases the incidence of neutropenia (including febrile neutropenia) and the incidence of thrombocytopenia.
Monitor complete blood cell counts periodically during treatment. This should be done as per clinical judgment but not less frequently than prescribing information for background therapies. Monitor patients with neutropenia for signs of infection. Darzalex dose delay may be required to allow recovery of blood cell counts. No dose reduction of Darzalex is recommended. Consider supportive care with transfusions or growth factors.

Hepatitis B virus (HBV) reactivation.

Hepatitis B virus (HBV) reactivation, in some cases fatal, has been reported in patients treated with Darzalex. HBV screening should be performed in all patients before initiation of treatment with Darzalex.
For patients with evidence of positive HBV serology, monitor for clinical and laboratory signs of HBV reactivation during, and for at least six months following the end of Darzalex treatment. Manage patients according to current clinical guidelines. Consider consulting a hepatitis disease expert as clinically indicated.
In patients who develop reactivation of HBV while on Darzalex, suspend treatment with Darzalex and any concomitant steroids, chemotherapy, and institute appropriate treatment. Resumption of Darzalex treatment in patients whose HBV reactivation is adequately controlled should be discussed with physicians with expertise in managing HBV.

Use in the elderly.

No overall differences in safety or effectiveness were observed between older (≥ 65 years) and younger patients.
No dose adjustments are considered necessary (see Section 5.2 Pharmacokinetic Properties).

Paediatric use.

The safety and efficacy of Darzalex have not been established in paediatric patients.

Effect on laboratory tests.

Interference with indirect antiglobulin test (indirect Coombs' test).

Daratumumab binds to CD38 found at low levels on red blood cells (RBCs) and may result in a positive indirect Coombs' test. Daratumumab-mediated positive indirect Coombs' test may persist for up to 6 months after the last daratumumab infusion. It should be recognised that daratumumab bound to RBCs may mask detection of antibodies to minor antigens in the patient's serum. The determination of a patient's ABO and Rh blood type are not impacted.
Type and screen patients prior to starting Darzalex.
In the event of a planned transfusion notify blood transfusion centres of this interference with indirect antiglobulin tests (see Section 4.5 Interactions with Other Medicines and Other Forms of Interactions). If an emergency transfusion is required, non-cross-matched ABO/RhD-compatible RBCs can be given per local blood bank practices.

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 Section 4.5 Interactions with Other Medicines and Other Forms of Interactions). This interference can impact the determination of complete response and of disease progression in some patients with IgG kappa myeloma protein.

4.5 Interactions with Other Medicines and Other Forms of Interactions

No drug-drug interaction studies have been performed.
Clinical pharmacokinetic assessments of daratumumab in combination with lenalidomide, pomalidomide, thalidomide, bortezomib and dexamethasone indicated no clinically-relevant drug-drug interaction between daratumumab and these small molecule medicinal products.

Effects of Darzalex on laboratory tests.

Interference with indirect antiglobulin test (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, Kell-negative units should be supplied after ruling out or identifying alloantibodies using DTT-treated RBCs (see Section 4.4 Special Warnings and Precautions for Use, Effect on laboratory tests).

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). This can lead to false positive SPE and IFE assay results for patients with IgG kappa myeloma protein impacting initial assessment of complete responses by International Myeloma Working Group (IMWG) criteria. In patients with persistent very good partial response, consider other methods to evaluate the depth of response.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

No data are available to determine potential effects of daratumumab on fertility in males or females.
(Category C)
There are no human or animal data to assess the risk of Darzalex use during pregnancy. IgG1 monoclonal antibodies are known to cross the placenta after the first trimester of pregnancy. Therefore, Darzalex should not be used during pregnancy unless the benefit of treatment to the woman is considered to outweigh the potential risks to the foetus. If the patient becomes pregnant while taking this drug, the patient should be informed of the potential risk to the fetus.
To avoid exposure to the foetus, women of reproductive potential should use effective contraception during and for 3 months after cessation of Darzalex treatment. However, when Darzalex is used in combination with lenalidomide and dexamethasone, or thalidomide and dexamethasone, patients must also follow advice about use in pregnancy of those products - see below.

Use of Darzalex with lenalidomide or thalidomide.

Lenalidomide and thalidomide (both Pregnancy Category X) are associated with risk of foetal harm, including severe life-threatening human birth defects. Refer to the lenalidomide and thalidomide PI for additional information. Patients receiving Darzalex in combination with lenalidomide and dexamethasone, or thalidomide and dexamethasone, should adhere to the pregnancy prevention programme of these medicines.
It is not known whether daratumumab is excreted into human or animal milk or affects milk production. There are no studies to assess the effect of daratumumab on the breast-fed infant.
Maternal IgG is excreted in human milk, but does not enter the neonatal and infant circulations in substantial amounts as they are degraded in the gastrointestinal tract and not absorbed. Because the risks of Darzalex to the infant from oral ingestion are unknown, a decision should be made whether to discontinue breast-feeding, or discontinue Darzalex therapy, taking into account the benefit of breast feeding for the child and the benefit of therapy for the woman.

4.7 Effects on Ability to Drive and Use Machines

Darzalex has no or negligible influence on the ability to drive and use machines. However, fatigue has been reported in patients taking daratumumab and this should be taken into account when driving or using machines.

4.8 Adverse Effects (Undesirable Effects)

Throughout this section, adverse reactions are presented. Adverse reactions are adverse events that were considered to be reasonably associated with the use of daratumumab based on the comprehensive assessment of the available adverse event information. A causal relationship with daratumumab cannot be reliably established in individual cases. Further, 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 clinical practice.
The safety data described below reflect exposure to Darzalex (16 mg/kg) in 2459 patients with multiple myeloma including 2303 patients who received Darzalex in combination with background regimens and 156 patients who received Darzalex as monotherapy.

Newly diagnosed multiple myeloma.

Combination treatment with bortezomib, thalidomide and dexamethasone (DVTd).

Adverse reactions described in Table 6 reflect exposure to Darzalex up to Day 100 post-transplant in a Phase 3 active-controlled study, Study MMY3006 (see Section 5.1 Pharmacodynamic Properties, Clinical trials). The median duration of induction/ASCT/consolidation treatment was 8.9 (range: 7.0 to 12.0) months for the DVTd group and 8.7 (range: 6.4 to 11.5) months for the VTd group. The most frequent adverse reactions (> 20%) were infusion reactions, nausea, pyrexia, upper respiratory tract infection and bronchitis. Serious adverse reactions with a 2% greater incidence in the DVTd arm compared to the VTd arm were bronchitis (DVTd 2% vs VTd < 1%) and pneumonia (DVTd 6% vs VTd 4%).
Laboratory abnormalities worsening during treatment from baseline listed in Table 7.

Combination treatment with bortezomib, melphalan and prednisone.

Adverse reactions described in Table 8 reflect exposure to Darzalex for a median treatment duration of 14.7 months (range: 0 to 25.8 months) for the daratumumab, bortezomib, melphalan and prednisone (D-VMP) group, and median treatment duration of 12 months (range: 0.1 to 14.9 months) for the VMP group in a Phase 3 active-controlled study (Study MMY3007). The most frequent adverse reactions (≥ 20%) were infusion reactions, upper respiratory tract infection and oedema peripheral. Serious adverse reactions with at least a 2% greater incidence in the D-VMP arm compared to the VMP arm were pneumonia (D-VMP 11% vs VMP 4%), upper respiratory tract infection (D-VMP 5% vs VMP 1%), and pulmonary oedema (D-VMP 2% vs VMP 0%).

Adverse reactions described in Table 10 reflect exposure to Darzalex for a median treatment duration of 25.3 months (range: 0.1 to 40.44 months) for the daratumumab-lenalidomide-dexamethasone (DRd) group and median treatment duration of 21.3 months (range: 0.03 to 40.64 months) for the lenalidomide-dexamethasone group (Rd) in a Phase 3 active-controlled study (Study MMY3008). The most frequent (≥ 20%) adverse reactions were infusion reactions, diarrhoea, constipation, nausea, peripheral oedema, fatigue, back pain, asthenia, pyrexia, upper respiratory tract infection, bronchitis, pneumonia, decreased appetite, muscle spasms, peripheral sensory neuropathy, dyspnoea and cough. Serious adverse reactions with a 2% greater incidence in the DRd arm compared to the Rd arm were dehydration (DRd 2% vs Rd < 1%), bronchitis (DRd 4% vs Rd 2%) and pneumonia (DRd 15% vs Rd 8%).
Laboratory abnormalities worsening during treatment from baseline listed in Table 11.

Relapsed/refractory multiple myeloma.

Combination treatment with bortezomib and dexamethasone.

Adverse reactions described in Table 12 reflect exposure to Darzalex for a median treatment duration of 6.5 months (range: 0 to 14.8 months) for the daratumumab-bortezomib-dexamethasone (DVd) group and median treatment duration of 5.2 months (range: 0.2 to 8.0 months) for the bortezomib-dexamethasone group (Vd) in a Phase 3 active-controlled study (Study MMY3004). The most frequent adverse reactions (> 20%) were infusion reactions, diarrhoea, peripheral oedema, upper respiratory tract infection, peripheral sensory neuropathy, cough and dyspnoea. Serious adverse reactions included diarrhoea, upper respiratory tract infection and atrial fibrillation. Adverse reactions resulted in discontinuations for 7% (n = 18) of patients in the DVd arm versus 9% (n = 22) in the Vd arm.
Laboratory abnormalities worsening during treatment are listed in Table 13.

Combination treatment with lenalidomide and dexamethasone.

Adverse reactions described in Table 14 reflect exposure to Darzalex for a median treatment duration of 13.1 months (range: 0 to 20.7 months) daratumumab-lenalidomide-dexamethasone (DRd) group and median treatment duration of 12.3 months (range: 0.2 to 20.1 months) for the lenalidomide-dexamethasone group (Rd) in a Phase 3 active-controlled study (Study MMY3003). The most frequent adverse reactions were infusion reactions, diarrhoea, nausea, fatigue, pyrexia, upper respiratory tract infection, muscle spasms, cough and dyspnoea. Serious adverse reactions were pneumonia, upper respiratory tract infection, influenza and pyrexia. Adverse reactions resulted in discontinuations for 7% (n = 19) of patients in the DRd arm versus 8% (n = 22) in the Rd arm.
Laboratory abnormalities worsening during treatment from baseline are listed in Table 15.

Monotherapy.

The data described below reflect exposure to Darzalex in three pooled open label clinical studies that included 156 patients with relapsed and refractory multiple myeloma treated with Darzalex at 16 mg/kg. The median duration of Darzalex treatment was 3.3 months, with the longest duration of treatment being 14.2 months. Adverse reactions occurring at a rate of ≥ 10% are presented in Table 16. The most frequently reported adverse reactions (≥ 20%) were IRRs, fatigue, nausea, back pain, anaemia, neutropenia and thrombocytopenia. Four percent of patients discontinued Darzalex treatment due to adverse reactions, none of which were considered drug related.
Frequencies are defined as very common (≥ 1/10), common (≥ 1/100 to < 1/10), uncommon (≥ 1/1000 to < 1/100), rare (≥ 1/10,000 to < 1/1000) and very rare (< 1/10,000).

Infusion-related reactions.

In clinical trials (monotherapy and combination treatments; N = 2066) the incidence of any grade IRRs was 37% with the first (16 mg/kg, Week 1) infusion of Darzalex, 2% with the Week 2 infusion, and cumulatively 6% with subsequent infusions. Less than 1% of patients had a Grade 3/4 infusion reaction at Week 2 or subsequent infusions.
The median time to onset of a reaction was 1.5 hours (range: 0 to 72.8 hours). The incidence of infusion modifications due to reactions was 36%. Median durations of 16 mg/kg infusions for the 1st, 2nd and subsequent infusions were approximately 7, 4 and 3 hours respectively.
Severe IRRs included bronchospasm, dyspnoea, laryngeal oedema, pulmonary oedema, hypoxia, and hypertension. Other adverse infusion-related reactions included nasal congestion, cough, chills, throat irritation, vomiting and nausea (see Section 4.4 Special Warnings and Precautions for Use).
In patients with newly diagnosed multiple myeloma, 5 subjects (1.4%) in the D-VMP group (Study MMY3007), 3 subjects (0.6%) in the D-VTd group (Study MMY3006) and 1 subject (0.7%) in the D-Rd group (Study MMY3008) discontinued Darzalex due to IRRs. In combination studies in relapsed/refractory multiple myeloma, 5 subjects (0.8%) discontinued Darzalex treatment due to IRRs. In the monotherapy study, no subject treated with 16 mg/kg Darzalex discontinued treatment due to an IRR.
When Darzalex dosing was interrupted in the setting of ASCT (Study MMY3006) for a median of 3.75 (range: 2.4; 6.9) months, upon re-initiation of Darzalex the incidence of IRRs was 11% at first infusion following ASCT. Infusion rate/dilution volume used upon re-initiation was that used for the last Darzalex infusion prior to interruption due to ASCT. IRRs occurring at re-initiation of Darzalex following ASCT were consistent in terms of symptoms and severity (Grade 3/4: < 1%) with those reported in previous studies at Week 2 or subsequent infusions.
In Study MMY1001, patients receiving daratumumab combination treatment (n = 97) were administered the first 16 mg/kg daratumumab dose at Week 1 split over two days i.e. 8 mg/kg on Day 1 and Day 2, respectively. The incidence of any grade IRRs was 42%, with 36% of patients experiencing IRRs on Day 1 of Week 1, 4% on Day 2 of Week 1, and 8% with subsequent infusions. The median time to onset of a reaction was 1.8 hours (range: 0.1 to 5.4 hours). The incidence of infusion interruptions due to reactions was 30%. Median durations of infusions were 4.2 hours for Week 1-Day 1, 4.2 hours for Week 1-Day 2, and 3.4 hours for the subsequent infusions.

Infections.

In patients receiving Darzalex combination therapy, Grade 3 or 4 infections were reported as follows:
Relapsed/refractory patient studies: DVd: 21%, Vd: 19%, DRd: 28%, Rd: 23%; DPd: 28%; DKda: 36%, Kda: 27%; DKdb: 21%.
a Where carfilzomib 20/56 mg/m2 was administered twice-weekly.
b Where carfilzomib 20/70 mg/m2 was administered once-weekly.
Newly diagnosed patient studies: D-VMP: 23%, VMP: 15%; DRd: 32%, Rd: 23%; DVTd: 22%, VTd: 20%.
Pneumonia was the most commonly reported severe (Grade 3 or 4) infection across studies. In the active controlled studies, discontinuations from treatment due to infections occurred in 1-4% of patients. Fatal infections were primarily due to pneumonia and sepsis.
In patients receiving Darzalex combination therapy, fatal infections (Grade 5) were reported as follows:
Relapsed/refractory patient studies: DVd: 1%, Vd: 2%; DRd: 2%, Rd: 1%; DPd: 2%; DKda: 5%, Kda: 3%; DKdb: 0%.
a Where carfilzomib 20/56 mg/m2 was administered twice-weekly.
b Where carfilzomib 20/70 mg/m2 was administered once-weekly.
Newly diagnosed patient studies: D-VMP: 1%, VMP: 1%; DRd: 2%, Rd: 2%; DVTd: 0%, VTd: 0%.

Other adverse reactions.

Other adverse reactions reported in patients treated with daratumumab in clinical trials are listed in Table 17.

Other special population.

Of the 2459 patients who received Darzalex at the recommended dose, 38% were 65 to 75 years of age, and 15% were 75 years of age or older. No overall differences in effectiveness were observed based on age. The incidence of serious adverse reactions was higher in older than in younger patients (see Section 5.1 Pharmacodynamic Properties, Clinical trials). Among patients with relapsed and refractory multiple myeloma (n = 1213), the most common serious adverse reactions that occurred more frequently in elderly (≥ 65 years of age) were pneumonia and sepsis. Among patients with newly diagnosed multiple myeloma who are ineligible for autologous stem cell transplant (n = 710), the most common serious adverse reaction that occurred more frequently in elderly (≥ 75 years of age) was pneumonia.

Postmarketing data.

Adverse reactions identified during postmarketing experience with Darzalex are included in Table 18. The frequencies are provided according to the following convention:
Very common: ≥ 1/10; Common: ≥ 1/100 to < 1/10; Uncommon: ≥ 1/1000 to < 1/100; Rare: ≥ 1/10,000 to < 1/1000; Very rare: < 1/10,000, including isolated reports; Not known: frequency cannot be estimated from the available data.
In Table 18, adverse reactions are presented by frequency category based on spontaneous reporting rates, as well as frequency category based on precise incidence in a clinical trial, when known.

Reporting suspected adverse reactions.

Healthcare professionals are asked to report any suspected adverse reactions at https://www.tga.gov.au/reporting-problems.

4.9 Overdose

Symptoms and signs.

There has been no experience of overdosage in clinical studies. Doses up to 24 mg/kg have been administered intravenously in a clinical study without reaching the maximum tolerated dose.

Treatment.

There is no known specific antidote for Darzalex overdose. In the event of an overdose, the patient should be monitored for any signs or symptoms of adverse effects and appropriate symptomatic treatment be instituted immediately.
For information on the management of overdose, contact the Poison Information Centre on 131126 (Australia).

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Pharmacotherapeutic group: monoclonal antibodies, ATC code: L01XC24.

Mechanism of action.

Daratumumab is an IgG1κ human monoclonal antibody (mAb) that binds to the CD38 protein expressed at a high level on the surface of cells in a variety of haematological malignancies, including multiple myeloma tumour cells, as well as other cell types and tissues at various levels. CD38 protein has multiple functions such as receptor mediated adhesion, signalling and enzymatic activity.
Daratumumab has been shown to inhibit the in vivo growth of CD38-expressing tumour cells. Based on in vitro studies, daratumumab may utilise multiple effector functions, resulting in immune mediated tumour cell death. These studies suggest that daratumumab can induce tumour cell lysis through complement-dependent cytotoxicity (CDC), antibody-dependent cell-mediated cytotoxicity (ADCC), and antibody-dependent cellular phagocytosis (ADCP) in malignancies expressing CD38. A subset of myeloid derived suppressor cells (CD38+MDSCs), regulatory T cells (CD38+Tregs) and B cells (CD38+Bregs) are decreased by daratumumab. T cells (CD3+, CD4+, and CD8+) are also known to express CD38 depending on the stage of development and the level of activation. Significant increases in CD4+ and CD8+ T cell absolute counts, and percentages of lymphocytes, were observed with Darzalex treatment in peripheral whole blood and bone marrow. T-cell receptor DNA sequencing verified that T-cell clonality was increased with Darzalex treatment, indicating immune modulatory effects that may contribute to clinical response.
Daratumumab induced apoptosis in vitro after Fc mediated cross linking. In addition, daratumumab modulated CD38 enzymatic activity, inhibiting the cyclase enzyme activity and stimulating the hydrolase activity. The significance of these in vitro effects in a clinical setting, and the implications on tumour growth, are not well-understood.

Pharmacodynamic effects.

Natural killer (NK) cell and T-cell count.

NK cells are known to express high levels of CD38 and are susceptible to daratumumab mediated cell lysis. Decreases in absolute counts and percentages of total NK cells (CD16+CD56+) and activated (CD16+CD56dim) NK cells in peripheral whole blood and bone marrow were observed with Darzalex treatment. However, baseline levels of NK cells did not show an association with clinical response.

Immunogenicity.

In multiple myeloma patients treated with Darzalex in monotherapy and combination clinical trials, less than 1% of patients developed treatment-emergent anti-daratumumab antibodies. A total of 6/1713 subjects tested (0.4%) were positive for anti-daratumumab antibodies in combined and monotherapy daratumumab IV studies. Of these 6, 4 tested positive for neutralising antibodies.
Immunogenicity data are highly dependent on the sensitivity and specificity of the test methods used. Additionally, the observed incidence of a positive result in a test method may be influenced by several factors, including sample handling, timing of sample collection, drug interference, concomitant medication and the underlying disease. Therefore, comparison of the incidence of antibodies to daratumumab with the incidence of antibodies to other products may be misleading.

Cardiac electrophysiology.

Daratumumab as a large protein has a low likelihood of direct ion channel interactions. The effect of daratumumab on the QTc interval was evaluated in an open-label study for 83 patients (Study GEN501) with relapsed and refractory multiple myeloma following daratumumab infusions (4 to 24 mg/kg). Linear mixed PK-PD analyses indicated no large increase in mean QTcF interval (i.e. greater than 20 ms) at daratumumab Cmax. The mean time-averaged QTcF interval increase was 10.1 ms (n = 3) and 4.3 ms (n = 42) in the 16 mg/kg cohorts from these analyses.

Clinical trials.

Newly diagnosed multiple myeloma.

Combination treatment with bortezomib, thalidomide and dexamethasone in patients eligible for autologous stem cell transplant (ASCT).

Study MMY3006, an open-label, randomised, active-controlled Phase 3 study compared induction and consolidation treatment with Darzalex 16 mg/kg in combination with bortezomib, thalidomide and dexamethasone (DVTd) to treatment with bortezomib, thalidomide and dexamethasone (VTd) in patients with newly diagnosed multiple myeloma eligible for ASCT. The consolidation phase of treatment began a minimum of 30 days post-ASCT, when the patient had recovered sufficiently, and engraftment was complete.
Bortezomib was administered by subcutaneous (SC) injection or intravenous (IV) injection at a dose of 1.3 mg/m2 body surface area twice weekly for two weeks (Days 1, 4, 8, and 11) of repeated 28-day (4-week) induction treatment cycles (Cycles 1-4) and two consolidation cycles (Cycles 5 and 6) following ASCT after Cycle 4. Thalidomide was administered orally at 100 mg daily during the six bortezomib cycles. Dexamethasone (oral or intravenous) was administered at 40 mg on Days 1, 2, 8, 9, 15, 16, 22 and 23 of Cycles 1 and 2, and at 40 mg on Days 1-2 and 20 mg on subsequent dosing days (Days 8, 9, 15, 16) of Cycles 3-4. Dexamethasone 20 mg was administered on Days 1, 2, 8, 9, 15, 16 in Cycles 5 and 6. On the days of Darzalex infusion, the dexamethasone dose was administered intravenously as a pre-infusion medication. Dose adjustments for bortezomib, thalidomide and dexamethasone were applied according to manufacturer's Product Information. See Table 19.
A total of 1085 patients were randomised: 543 to the DVTd arm and 542 to the VTd arm. The baseline demographic and disease characteristics were similar between the two treatment groups. The median age was 58 (range: 22 to 65 years). The majority were male (59%), 48% had an Eastern Cooperative Oncology Group (ECOG) performance score of 0, 42% had an ECOG performance score of 1 and 10% had an ECOG performance score of 2. Forty percent had ISS Stage I, 45% had ISS Stage II and 15% had ISS Stage III disease.
Efficacy was evaluated by the stringent Complete Response (sCR) rate at Day 100 post-transplant. See Table 20.
With a median follow-up of 18.8 months, the primary analysis of PFS in Study MMY3006 demonstrated an improvement in Progression Free Survival (PFS) in the DVTd arm as compared to the VTd arm; the median PFS had not been reached in either arm. Treatment with DVTd resulted in a reduction in the risk of progression or death by 53% compared to VTd alone (HR = 0.47; 95% CI: 0.33, 0.67; p < 0.0001). Results of an updated PFS analysis after a median follow-up of 44.5 months showed that median PFS was not reached in the DVTd arm and was 51.5 months in the VTd arm (HR = 0.58; 95% CI: 0.47, 0.71; p < 0.0001). See Figure 1.

Combination treatment with bortezomib, melphalan and prednisone (VMP) in patients ineligible for autologous stem cell transplant.

Study MMY3007, an open-label, randomised, active-controlled Phase 3 study, compared treatment with Darzalex 16 mg/kg in combination with bortezomib, melphalan and prednisone (D-VMP), to treatment with VMP in patients with newly diagnosed multiple myeloma. Bortezomib was administered by subcutaneous (SC) injection at a dose of 1.3 mg/m2 body surface area twice weekly at Weeks 1, 2, 4 and 5 for the first 6-week cycle (Cycle 1; 8 doses), followed by once weekly administrations at Weeks 1, 2, 4 and 5 for eight additional 6-week cycles (Cycles 2-9; 4 doses per cycle). Melphalan at 9 mg/m2, and prednisone at 60 mg/m2 were orally administered on Days 1 to 4 of the nine 6-week cycles (Cycles 1-9). Darzalex treatment was continued until disease progression or unacceptable toxicity. See Table 21.
A total of 706 patients were randomised; 350 to the D-VMP arm and 356 to the VMP arm. The baseline demographic and disease characteristics were similar between the two treatment groups. The median age was 71 (range: 40-93) years, with 30% of the patients ≥ 75 years of age. The majority were White (85%), female (54%), 25% and had an ECOG performance score of 0, 50% had an ECOG performance score of 1 and 25% had an ECOG performance score of 2. Patients had IgG/IgA/light chain myeloma in 64%/22%/10% of instances, 19% had ISS Stage I, 42% had ISS Stage II and 38% had ISS Stage III disease. Efficacy was evaluated by PFS based on IMWG criteria.
With a median follow-up of 16.5 months, the primary analysis of PFS in Study MMY3007 demonstrated an improvement in the D-VMP arm as compared to the VMP arm; the median PFS had not been reached in the D-VMP arm and was 18.1 months in the VMP arm (HR = 0.5; 95% CI: 0.38, 0.65; p < 0.0001), representing 50% reduction in the risk of disease progression or death in patients treated with D-VMP. Results of an updated PFS analysis after a median follow-up of 40 months continued to show an improvement in PFS for patients in the D-VMP arm compared with the VMP arm. Median PFS was 36.4 months (95% CI: 32.1, 45.9) in the D-VMP arm and 19.3 months (95% CI: 18.0, 20.4) in the VMP arm. See Figure 2.
After a median follow-up of 40 months, an improvement in overall survival (OS) was demonstrated for the D-VMP arm (83 deaths, 23.7%) as compared to the VMP arm (126 deaths, 35.6%) (HR = 0.60; 95% CI: 0.46, 0.80; p = 0.0003), representing a 40% reduction in the risk of death in patients treated in the D-VMP arm. Median OS was not reached for either arm. See Figure 3.
Additional efficacy results from Study MMY3007 are presented in Table 22.
In responders, the median time to response was 0.79 months (range: 0.4 to 15.5 months) in the D-VMP group and 0.82 months (range: 0.7 to 12.6 months) in the VMP group. The median duration of response had not been reached in the D-VMP group and was 21.3 months (range: 18.4, not estimable) in the VMP group.

Combination treatment with lenalidomide and dexamethasone in patients ineligible for autologous stem cell transplant.

Study MMY3008 an open-label, randomised, active-controlled Phase 3 study, compared treatment with Darzalex 16 mg/kg in combination with lenalidomide and low-dose dexamethasone (DRd) to treatment with lenalidomide and low-dose dexamethasone (Rd) in patients with newly diagnosed multiple myeloma. Lenalidomide (25 mg once daily orally on Days 1-21 of repeated 28-day [4-week] cycles) was given with low dose oral or intravenous dexamethasone 40 mg/week (or a reduced dose of 20 mg/week for patients > 75 years or body mass index [BMI] < 18.5). On Darzalex infusion days, the dexamethasone dose was given as a pre-infusion medication. Dose adjustments for lenalidomide and dexamethasone were applied according to manufacturer's Product Information. Treatment was continued in both arms until disease progression or unacceptable toxicity. See Table 23.
A total of 737 patients were randomised: 368 to the DRd arm and 369 to the Rd arm. The baseline demographic and disease characteristics were similar between the two treatment groups. The median age was 73 (range: 45-90) years, with 44% of the patients ≥ 75 years of age. The majority were White (92%), male (52%), 34% had an ECOG performance score of 0, 50% had an ECOG performance score of 1 and 17% had an ECOG performance score of ≥ 2. Twenty-seven percent had International Staging System (ISS) Stage I, 43% had ISS Stage II and 29% had ISS Stage III disease. Efficacy was evaluated by progression free survival (PFS) based on IMWG criteria.
With a median follow-up of 28 months, the primary analysis of PFS in Study MMY3008 demonstrated an improvement in the DRd arm as compared to the Rd arm; the median PFS had not been reached in the DRd arm and was 31.9 months in the Rd arm (hazard ratio [HR] = 0.56; 95% CI: 0.43, 0.73; p < 0.0001), representing 44% reduction in the risk of disease progression or death in patients treated with DRd. Results of an updated PFS analysis after a median follow-up of 56 months continued to show an improvement in PFS for patients in the DRd arm compared with the Rd arm. Median PFS was not reached in the DRd arm and 34.4 months (95% CI, 29.6, 39.2) in the Rd arm (HR = 0.53; 95% CI: 0.43, 0.66; p < 0.0001). See Figure 4.
After a median follow-up of 56 months, an improvement in OS was demonstrated for the DRd arm (117 deaths, 31.8%) as compared to the Rd arm (156 deaths, 42.3%) (HR = 0.68; 95% CI: 0.53, 0.86; p = 0.0013), representing a 32% reduction in the risk of death in patients treated in the DRd arm. Median OS was not reached for either arm. The 60 month survival rate was 66% (95% CI: 61, 71) in the DRd arm and was 53% (95% CI: 47, 59) in the Rd arm. See Figure 5.
Additional efficacy results from Study MMY3008 are presented in Table 24.
In responders, the median time to response was 1.05 months (range: 0.2 to 12.1 months) in the DRd group and 1.05 months (range: 0.3 to 15.3 months) in the Rd group. The median duration of response had not been reached in the DRd group and was 34.7 months (95% CI: 30.8, not estimable) in the Rd group.
Relapsed/refractory multiple myeloma.

Combination treatment with bortezomib and dexamethasone.

Study MMY3004, an open-label, randomised, active-controlled Phase 3 trial, compared treatment with Darzalex 16 mg/kg in combination with bortezomib and dexamethasone (DVd), to treatment with bortezomib and dexamethasone (Vd) in patients with multiple myeloma who had received at least one prior therapy. Bortezomib was administered by SC injection or IV injection at a dose of 1.3 mg/m2 body surface area twice weekly for two weeks (Days 1, 4, 8, and 11) of repeated 21-day (3-week) treatment cycles, for a total of 8 cycles. Dexamethasone was administered orally at a dose of 20 mg on Days 1, 2, 4, 5, 8, 9, 11, and 12 of the 8 bortezomib cycles (80 mg/week for two out of three weeks of each of the bortezomib cycle) or a reduced dose of 20 mg/week for patients > 75 years, BMI < 18.5, poorly controlled diabetes mellitus or prior intolerance to steroid therapy. On the days of Darzalex infusion, 20 mg of the dexamethasone dose was administered as a pre-infusion medication. Darzalex was continued until disease progression or unacceptable toxicity. Patients refractory to bortezomib were excluded from the study. Dose adjustments for bortezomib and dexamethasone were applied according to manufacturer's Product Information. See Table 25.
A total of 498 patients were randomised; 251 to the DVd arm and 247 to the Vd arm. The baseline demographic and disease characteristics were similar between the Darzalex and the control arm. The median patient age was 64 years (range 30 to 88 years); 12% were ≥ 75 years, 57% were male; 87% Caucasian, 5% Asian and 4% African American. Patients had received a median of 2 prior lines of therapy and 61% of patients had received prior autologous stem cell transplantation (ASCT). Sixty-nine percent (69%) of patients had received a prior PI (66% received bortezomib) and 76% of patients received an IMiD (42% received lenalidomide). At baseline, 32% of patients were refractory to the last line of treatment and the proportions of patients refractory to any specific prior therapy were well balanced between the treatment groups. Thirty-three percent (33%) of patients were refractory to an IMiD only, and 28% were refractory to lenalidomide. Efficacy was evaluated by PFS based on IMWG criteria.
With a median follow-up of 7.4 months, the primary analysis of PFS in Study MMY3004 demonstrated an improvement in the DVd arm as compared to the Vd arm; the median PFS had not been reached in the DVd arm and was 7.2 months in the Vd arm (HR [95% CI]: 0.39 [0.28, 0.53]; p-value < 0.0001), representing a 61% reduction in the risk of disease progression or death for patients treated with DVd versus Vd. Results of an updated PFS analysis after a median follow-up of 50 months continued to show an improvement in PFS for patients in the DVd arm compared with the Vd arm. Median PFS was 16.7 months (95% CI: 13.1, 19.4) in the DVd arm and 7.1 months (95% CI: 6.2, 7.7) in the Vd arm (HR [95% CI]: 0.31 [0.24, 0.39]; p-value < 0.0001), representing a 69% reduction in the risk of disease progression or death in patients treated with DVd versus Vd. See Figure 6.
After a median follow-up of 73 months, an improvement in OS was demonstrated for the DVd arm (148 deaths, 59.0%) as compared to the Vd arm (171 deaths, 69.2%) (HR = 0.74; 95% CI: 0.59, 0.92; p = 0.0075), representing a 26% reduction in the risk of death in patients treated in the DVd arm. The median OS was 49.6 months (95% CI: 42.2, 62.3) in the DVd arm and 38.5 months (95% CI: 31.2, 46.2) in the Vd arm. The 72-month survival rate was 39% (95% CI: 33, 45) in the DVd arm and was 25% (95% CI: 20, 31) in the Vd arm. See Figure 7.
Additional efficacy results from Study MMY3004 are presented in Table 26.

Combination treatment with lenalidomide and dexamethasone.

Study MMY3003, an open-label, randomised, active-controlled Phase 3 trial, compared treatment with Darzalex 16 mg/kg in combination with lenalidomide and low-dose dexamethasone (DRd) to treatment with lenalidomide and low-dose dexamethasone (Rd) in patients with multiple myeloma who had received at least one prior therapy.
Lenalidomide (25 mg once daily orally on Days 1-21 of repeated 28-day [4-week] cycles) was given with low dose oral or intravenous dexamethasone 40 mg/week (or a reduced dose of 20 mg/week for patients > 75 years or BMI < 18.5). On Darzalex infusion days, 20 mg of the dexamethasone dose was given as a pre-infusion medication and the remainder given the day after the infusion. Dose adjustments for lenalidomide and dexamethasone were applied according to manufacturer's Product Information. Treatment was continued in both arms until disease progression or unacceptable toxicity. Patients refractory to lenalidomide were excluded from the study. See Table 27.
A total of 569 patients were randomised; 286 to the DRd arm and 283 to the Rd arm. The baseline demographic and disease characteristics were similar between the Darzalex and the control arm. The median patient age was 65 years (range 34 to 89 years), 11% were ≥ 75 years, 59% were male; 69% Caucasian, 18% Asian, and 3% African American. Patients had received a median of 1 prior line of therapy. Sixty-three percent (63%) of patients had received prior autologous stem cell transplantation (ASCT). The majority of patients (86%) received a prior proteasome inhibitor (PI), 55% of patients had received a prior immunomodulatory agent (IMiD), including 18% of patients who had received prior lenalidomide, and 44% of patients had received both a prior PI and IMiD. At baseline, 27% of patients were refractory to the last line of treatment. Eighteen percent (18%) of patients were refractory to a PI only, and 21% were refractory to bortezomib. Efficacy was evaluated by PFS based on IMWG criteria.
With a median follow-up of 13.5 months, the primary analysis of PFS in Study MMY3003 demonstrated an improvement in the DRd arm as compared to the Rd arm; the median PFS had not been reached in the DRd arm and was 18.4 months in the Rd arm (HR = 0.37; 95% CI: 0.27, 0.52; p < 0.0001) representing 63% reduction in the risk of disease progression or death in patients treated with DRd (Figure 8). Results of an updated PFS analysis after a median follow-up of 55 months continued to show an improvement in PFS for patients in the DRd arm compared with the Rd arm. Median PFS was 45.0 months (95% CI: 34.1, 53.9) in the DRd arm and 17.5 months (95% CI: 13.9, 20.8) in the Rd arm (HR = 0.44; 95% CI: 0.35, 0.54; p < 0.0001), representing a 56% reduction in the risk of disease progression or death in patients treated with DRd.
After a median follow-up of 80 months, an improvement in OS was demonstrated for the DRd arm (153 deaths, 53.5%) as compared to the Rd arm (175 deaths, 61.8%) (HR = 0.73; 95% CI: 0.58, 0.91; p = 0.0044), representing a 27% reduction in the risk of death in patients treated in the DRd arm. The median OS was 67.6 months (95% CI: 53.1, 80.5) in the DRd arm and 51.8 months (95% CI: 44.0, 60.0) in the Rd arm. The 78-month survival rate was 47% (95% CI: 41, 52) in the DRd arm and was 35% (95% CI: 30, 41) in the Rd arm. See Figure 9.
Additional efficacy results from Study MMY3003 are presented in Table 28.

Monotherapy.

The clinical efficacy and safety of Darzalex monotherapy for the treatment of patients with relapsed and refractory multiple myeloma whose prior therapy included a proteasome inhibitor and an immunomodulatory agent, was demonstrated in two open-label studies.
In Study MMY2002, 106 patients with relapsed and refractory multiple myeloma received 16 mg/kg Darzalex until disease progression. The median patient age was 63.5 years (range, 31 to 84 years), 49% were male and 79% were Caucasian. Patients had received a median of 5 prior lines of therapy. Eighty percent of patients had received prior autologous stem cell transplantation (ASCT). Prior therapies included bortezomib (99%), lenalidomide (99%), pomalidomide (63%) and carfilzomib (50%). At baseline, 97% of patients were refractory to the last line of treatment, 95% were refractory to both, a PI and IMiD, 77% were refractory to alkylating agents, 63% were refractory to pomalidomide and 48% of patients were refractory to carfilzomib.
Efficacy results based on Independent Review Committee (IRC) assessment are presented in Table 29.
Overall response rate (ORR) in MMY2002 was similar regardless of type of prior anti-myeloma therapy. At a survival update with a median duration of follow up of 14.7 months, median OS was 17.5 months (95% CI: 13.7, not estimable).
In Study GEN501, 42 patients with relapsed and refractory multiple myeloma received 16 mg/kg Darzalex until disease progression. The median patient age was 64 years (range, 44 to 76 years), 64% were male and 76% were Caucasian. Patients in the study had received a median of 4 prior lines of therapy. Seventy-four percent of patients had received prior ASCT. Prior therapies included bortezomib (100%), lenalidomide (95%), pomalidomide (36%) and carfilzomib (19%). At baseline, 76% of patients were refractory to the last line of treatment, 64% were refractory to both a PI and IMiD, 60% were refractory to alkylating agents, 36% were refractory to pomalidomide and 17% were refractory to carfilzomib.
Pre-planned interim analysis showed that treatment with daratumumab at 16 mg/kg led to a 36% ORR with 5% CR and 5% VGPR. The median time to response was 1 (range: 0.5 to 3.2) month. The median duration of response was not reached (95% CI: 5.6 months, not estimable).
At a survival update with a median duration of follow up of 15.2 months, median OS was not reached (95% CI: 19.9 months, not estimable), with 74% of subjects still alive.

5.2 Pharmacokinetic Properties

The pharmacokinetics (PK) of daratumumab following intravenous administration of Darzalex monotherapy were evaluated in patients with relapsed and refractory multiple myeloma at dose levels from 0.1 mg/kg to 24 mg/kg. A population PK model of daratumumab was developed to describe the PK characteristics of daratumumab and to evaluate the influence of covariates on the disposition of daratumumab in patients with multiple myeloma. The population PK analysis included 223 patients receiving Darzalex monotherapy in two clinical trials (150 subjects received 16 mg/kg).
In the 1 to 24 mg/kg cohorts, peak serum concentrations (Cmax) after the first dose increased in approximate proportion to dose and volume of distribution was consistent with initial distribution into the plasma compartment. Increases in AUC were more than dose-proportional and clearance (CL) decreased with increasing dose. These observations suggest CD38 may become saturated at higher doses, after which the impact of target binding clearance is minimised and the clearance of daratumumab approximates the linear clearance of endogenous IgG1. Clearance also decreased with multiple doses, which may be related to tumour burden decreases.
Terminal half-life increases with increasing dose and with repeated dosing. The mean (standard deviation [SD]) estimated terminal half-life of daratumumab following the first 16 mg/kg dose was 9 (4.3) days. Based on population PK analysis, the mean (SD) half-life associated with non-specific linear elimination was approximately 18 (9) days; this is the terminal half-life that can be expected upon complete saturation of target mediated clearance and repeat dosing of daratumumab.
At the end of weekly dosing for the recommended monotherapy schedule and dose of 16 mg/kg, the mean (SD) serum Cmax value was 915 (410.3) microgram/mL, approximately 2.9-fold higher than following the first infusion. The mean (SD) predose (trough) serum concentration at the end of weekly dosing was 573 (331.5) microgram/mL.
Based on the population PK analysis of Darzalex monotherapy, daratumumab steady-state is achieved approximately 5 months into the every 4-week dosing period (by the 21st infusion), and the mean (SD) ratio of Cmax at steady-state to Cmax after the first dose was 1.6 (0.5). The mean (SD) central volume of distribution is 56.98 (18.07) mL/kg.
Three additional population PK analyses were conducted in patients with multiple myeloma that received daratumumab in various combination therapies (N = 1390). Daratumumab concentration-time profiles were similar following the monotherapy and combination therapies. The mean estimated terminal half-life associated with linear clearance in combination therapy was approximately 15-23 days.
Based on population PK analysis body weight was identified as a statistically significant covariate for daratumumab clearance. Therefore, body weight based dosing is an appropriate dosing strategy for the multiple myeloma patients.
Simulation of daratumumab pharmacokinetics was conducted for all recommended dosing schedules using individual PK parameters of patients with multiple myeloma (n = 1309). The simulation results confirmed that the split and single dosing for the first dose should provide similar PK, with the exception of the PK profile in the first day of the treatment.

Additional information on special populations.

Age and gender.

Based on population PK analyses in patients receiving monotherapy or various combination therapies, age (range: 31-93 years) had no clinically important effect on the PK of daratumumab, and the exposure of daratumumab was similar between younger (aged < 65 years, n = 518) and older (aged ≥ 65 to < 75 years, n = 761; age ≥ 75 years, n = 334) patients.
Gender did not affect exposure of daratumumab to a clinically relevant degree in population PK analyses.

Renal impairment.

No formal studies of Darzalex in patients with renal impairment have been conducted. Population PK analyses were performed based on pre-existing renal function data in patients receiving daratumumab monotherapy or various combination therapies, including 441 patients with normal renal function (creatinine clearance [CRCL] ≥ 90 mL/min), 621 with mild renal impairment (CRCL < 90 and ≥ 60 mL/min), 523 with moderate renal impairment (CRCL < 60 and ≥ 30 mL/min), and 27 with severe renal impairment or end stage renal disease (CRCL < 30 mL/min). No clinically important differences in exposure to daratumumab were observed between patients with renal impairment and those with normal renal function.

Hepatic impairment.

No formal studies of Darzalex in patients with hepatic impairment have been conducted. Population PK analyses were performed in patients receiving daratumumab monotherapy or various combination therapies, including 1404 patients with normal hepatic function (total bilirubin [TB] and aspartate aminotransferase [AST] ≤ upper limit of normal [ULN]), 189 with mild hepatic impairment (TB 1.0 x to 1.5 x ULN or AST > ULN), 8 patients with moderate (TB > 1.5 x to 3.0 x ULN; n = 7), or severe (TB > 3.0 x ULN; n = 1) hepatic impairment. No clinically important differences in the exposure to daratumumab were observed between patients with hepatic impairment and those with normal hepatic function.

Race.

Based on the population PK analyses in patients receiving either daratumumab monotherapy or various combination therapies, the exposure to daratumumab was similar between White (n = 1371) and non-White (n = 242) subjects.

5.3 Preclinical Safety Data

Genotoxicity.

Routine genotoxicity studies are generally not applicable to biologic pharmaceuticals as large proteins cannot diffuse into cells and cannot interact with DNA or chromosomal material.

Carcinogenicity.

Routine carcinogenicity studies are generally not applicable to biologic pharmaceuticals as large proteins cannot diffuse into cells and cannot interact with DNA or chromosomal material. No animal studies have been performed to establish the carcinogenic potential of daratumumab.
