Janssen Submits U.S. & EU Regulatory Applications Seeking Approval Of Darzalex (Daratumumab) Split Dosing Regimen

By: Press Release Reporter; Published: August 8, 2018 @ 7:30 am | Comments Disabled

Raritan, NJ and Beerse, Belgium (Press Release) – The Janssen Pharma­ceu­tical Com­panies of Johnson & Johnson announced today the sub­mission of a supple­mental Biologics License Application (sBLA) to the U.S. Food and Drug Admin­istra­tion (FDA) and a Type II Variation to the European Medicines Agency (EMA) seeking approval of a split dosing regi­men for DARZALEX® (dara­tu­mu­mab). The appli­ca­tions seek to update the Prescribing Information and Summary of Product Characteristics to provide health care professionals with the option to split the first in­fusion of DARZALEX® over two consecutive days. The sub­missions are sup­ported by data from the Phase 1b MMY1001 clin­i­cal trial, which dem­onstrated DARZALEX® phar­ma­co­ki­netics (PK) con­cen­tra­tions were com­parable re­gard­less of whether the first dose was admin­istered as a split in­fusion or single first in­fusion in patients with multiple myeloma.1 The safety profile of DARZALEX® was com­parable when admin­istered initially as a split or single dose.1

"We are committed to exploring options that may im­prove the admin­istra­tion profile of DARZALEX® and the over­all treat­ment ex­peri­ence for patients and physicians," said Craig Tendler, MD, Vice Pres­i­dent, Clinical Development and Global Medical Affairs, Janssen Research & Development, LLC. "We look for­ward to reviewing the data in sup­port of these appli­ca­tions with regulators and hope to make a DARZALEX® split-dose option avail­able to patients and health care professionals to provide addi­tional flexibility in admin­istra­tion of the initial in­fusion."

The regu­la­tory sub­mission is based on data from the global, multi-arm Phase 1b MMY1001 study in multiple myeloma, which eval­u­ated DARZALEX® in com­bi­na­tion with various treat­ment regi­mens.1 Splitting the first dose of DARZALEX® effectively reduced the duration of the first in­fusion and resulted in a similar rate and pattern of in­fusion reac­tions.1 Data from MMY1001 dem­onstrated that DARZALEX® con­cen­tra­tions were com­parable after admin­istra­tion of the first 16 mg/kg dose re­gard­less of whether it was admin­istered as a split in­fusion or single first in­fusion in all approved indi­ca­tions.1 No new safety events were observed with split dosing.1

In the U.S., DARZALEX® first received FDA approval in November 2015 as a mono­therapy for patients with multiple myeloma who have received at least three prior lines of ther­apy, in­­clud­ing a pro­te­a­some inhibitor (PI) and an immuno­modu­la­tory agent, or who are double refractory to a PI and an immuno­modu­la­tory agent.2 DARZALEX® received addi­tional approvals in November 2016 in com­bi­na­tion with lena­lido­mide and dexa­meth­a­sone, or bor­tez­o­mib and dexa­meth­a­sone, for the treat­ment of patients with multiple myeloma who have received at least one prior ther­apy.3 In June 2017, DARZALEX® received approval in com­bi­na­tion with poma­lido­mide and dexa­meth­a­sone for the treat­ment of patients with multiple myeloma who have received at least two prior ther­a­pies, in­­clud­ing lena­lido­mide and a PI.4 Most recently, in May 2018, DARZALEX® received approval in com­bi­na­tion with bor­tez­o­mib, mel­phalan and pred­ni­sone for the treat­ment of patients with newly diag­nosed multiple myeloma who are in­eli­gible for au­tol­o­gous stem cell trans­plant (ASCT), making it the first mono­clonal anti­body approved for newly diag­nosed patients with this disease.5

In the European Union (EU), DARZALEX® first received European Com­mis­sion approval in May 2016 as a mono­therapy for the treat­ment of adult patients with re­lapsed and refractory multiple myeloma, whose prior ther­apy in­cluded a PI and an immuno­modu­la­tory agent, and who have dem­onstrated disease pro­gres­sion on the last ther­apy.6 DARZALEX® received an addi­tional approval in April 2017 for use in com­bi­na­tion with lena­lido­mide and dexa­meth­a­sone, or bor­tez­o­mib and dexa­meth­a­sone, for the treat­ment of adult patients with multiple myeloma who have received at least one prior ther­apy.6 Finally, in July 2018, DARZALEX® received a pos­i­tive opinion from the Committee for Medicinal Products for Human Use (CHMP) rec­om­mending broadening the existing mar­ket­ing authori­za­tion for use in com­bi­na­tion with bor­tez­o­mib, mel­phalan and pred­ni­sone for the treat­ment of adult patients with newly diag­nosed multiple myeloma who are in­eli­gible for au­tol­o­gous stem cell trans­plant (ASCT).

In August 2012, Janssen Biotech, Inc. and Genmab A/S entered into a global license and devel­op­ment agree­ment, which granted Janssen an exclusive license to develop, manu­fac­ture and com­mer­cial­ize DARZALEX®.7 For the full U.S. Prescribing Information, please visit www.DARZALEX.com.

About DARZALEX® (dara­tu­mu­mab) Injection, for Intravenous Infusion

DARZALEX® (dara­tu­mu­mab) injection for in­tra­venous use is the first CD38-directed anti­body approved any­where in the world.5 CD38 is a surface protein that is highly ex­pressed across multiple myeloma cells, re­gard­less of disease stage.8 DARZALEX® is believed to induce tumor cell death through multiple immune-mediated mech­a­nisms of action, in­­clud­ing complement-dependent cyto­tox­icity (CDC), anti­body-dependent cell-mediated cyto­tox­icity (ADCC) and anti­body-dependent cellular phago­cytosis (ADCP), as well as through apop­tosis, in which a series of molecular steps in a cell lead to its death.5 Subsets of myeloid derived sup­pressor cells (MDSCs), CD38+ regu­la­tory T cells (Tregs) and CD38+ B cells (Bregs) were de­creased by DARZALEX®.5 DARZALEX® is being eval­u­ated in a com­pre­hen­sive clin­i­cal devel­op­ment pro­gram across a range of treat­ment settings in multiple myeloma, such as in frontline and re­lapsed settings.9,10,11,12,13,14,15,16 Additional studies are ongoing or planned to assess its poten­tial in other malignant and pre-malignant hema­to­logic diseases in which CD38 is ex­pressed, such as smol­der­ing myeloma, as well as in solid tumors.17,18,19 DARZALEX® is the first and only CD38-directed anti­body to receive regu­la­tory approval to treat multiple myeloma.5

About Multiple Myeloma

Multiple myeloma is an incurable blood cancer that occurs when malignant plasma cells grow un­con­trol­lably in the bone marrow.20,21 Refractory cancer occurs when a patient's disease is resistant to treat­ment or in the case of multiple myeloma, patients progress within 60 days of their last ther­apy.22,23 Relapsed cancer means the disease has returned after a period of initial, partial or com­plete remission.24 In 2018, it is esti­mated that 30,700 people will be diag­nosed, and 12,770 will die from the disease in the United States.25 Additionally, there were 40,570 new cases of multiple myeloma in Europe in 2015.26 The most recent five-year survival data for 2000-2007 show that across Europe, up to half of newly diag­nosed patients do not reach five-year survival.27 While some patients with multiple myeloma have no symp­toms at all, most patients are diag­nosed due to symp­toms, which can in­clude bone fracture or pain, low red blood counts, fatigue, cal­cium elevation, kidney problems or in­fec­tions.28

IMPORTANT SAFETY INFORMATION5

CONTRAINDICATIONS

DARZALEX® is con­tra­in­di­cated in patients with a history of severe hypersensitivity (eg, anaphylactic reac­tions) to dara­tu­mu­mab or any of the components of the for­mu­la­tion.

WARNINGS AND PRECAUTIONS

Infusion Reactions – DARZALEX® can cause severe and/or serious in­fusion reac­tions, in­­clud­ing anaphylactic reac­tions. In clin­i­cal trials, approx­i­mately half of all patients ex­peri­enced an in­fusion reac­tion. Most in­fusion reac­tions occurred during the first in­fusion and were grade 1-2. Infusion reac­tions can also occur with sub­se­quent in­fusions. Nearly all reac­tions occurred during in­fusion or within 4 hours of com­plet­ing an in­fusion. Prior to the in­tro­duc­tion of post-infusion medication in clin­i­cal trials, in­fusion reac­tions occurred up to 48 hours after in­fusion. Severe reac­tions have occurred, in­­clud­ing bron­cho­spasm, hypoxia, dyspnea, hyper­tension, laryngeal edema and pul­mo­nary edema. 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, and hypo­­tension.

Pre-medicate patients with antihistamines, anti­pyretics, and corticosteroids. Frequently monitor patients during the entire in­fusion. Interrupt in­fusion for reac­tions of any severity and institute medical man­agement as needed. Permanently dis­con­tinue ther­apy if an anaphylactic reac­tion or life-threatening (Grade 4) reac­tion occurs and institute appro­pri­ate emergency care. For patients with Grade 1, 2, or 3 reac­tions, reduce the in­fusion rate when re-starting the in­fusion.

To reduce the risk of delayed in­fusion reac­tions, admin­ister oral corticosteroids to all patients fol­low­ing DARZALEX® in­fusions. Patients with a history of chronic obstructive pul­mo­nary disease may require addi­tional post-infusion medications to man­age res­pira­tory com­pli­ca­tions. Consider pre­scrib­ing short- and long-acting bron­cho­di­lators and inhaled corticosteroids for patients with chronic obstructive pul­mo­nary disease.

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 in­fusion. Dara­tu­mu­mab bound to RBCs masks detection of anti­bodies to minor an­ti­gens in the patient's serum. The deter­mi­na­tion of a patient's ABO and Rh blood type are not impacted. Notify blood transfusion centers of this inter­fer­ence with serological testing and inform blood banks that a patient has received DARZALEX®. Type and screen patients prior to starting DARZALEX®.

Neutropenia – DARZALEX® may in­­crease neu­tro­penia induced by back­ground ther­apy. 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. DARZALEX® dose delay may be required to allow re­cov­ery of neu­tro­phils. No dose reduction of DARZALEX® is rec­om­mended. Consider sup­port­ive care with growth factors.

Thrombocytopenia – DARZALEX® may in­­crease thrombo­cytopenia induced by back­ground ther­apy. Monitor com­plete blood cell counts periodically during treat­ment according to manu­­fac­­turer's pre­scrib­ing in­­for­ma­tion for back­ground ther­a­pies. DARZALEX® dose delay may be required to allow re­cov­ery of platelets. No dose reduction of DARZALEX® is rec­om­mended. Consider sup­port­ive care with transfusions.

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. This inter­fer­ence can impact the deter­mi­na­tion of com­plete response and of disease pro­gres­sion in some patients with IgG kappa myeloma protein.
