JOHNSON & JOHNSON: Janssen Submits Application to U.S. FDA Seeking Approval of New DARZALEX® (daratumumab) Subcutaneous Formulation


Johnson & Johnson issued the following announcement on July 12.

The Janssen Pharmaceutical Companies of Johnson & Johnson announced today the submission of a Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) seeking approval of a new subcutaneous (SC) formulation of DARZALEX® (daratumumab), an intravenous (IV) treatment approved for certain patients with multiple myeloma.

The submission is supported by data from the Phase 3 COLUMBA (MMY3012) study first presented at the American Society of Clinical Oncology (ASCO) Annual Meeting that included a non-inferiority comparison to DARZALEX IV administration for co-primary endpoints of overall response rate and maximum Ctrough concentration. Data from the Phase 2 PLEIADES (MMY2040) study are also included in the BLA. The subcutaneous formulation of DARZALEX is co-formulated with recombinant human hyaluronidase PH20 (rHuPH20) [Halozyme's ENHANZE® drug delivery technology].

"This submission represents our commitment to develop innovative treatment options for people living with multiple myeloma," said Craig Tendler, M.D., Vice President, Clinical Development and Global Medical Affairs, Oncology, Janssen Research & Development, LLC. "The DARZALEX subcutaneous formulation showed non-inferiority to the existing IV formulation, both as a monotherapy and in combination with common background therapies, while administered with a considerably shorter infusion time. We look forward to working closely with the FDA in their review of the data supporting this regulatory application."

Today's submission follows two recent milestones for the DARZALEX intravenous formulation, including an approval of DARZALEX in combination with lenalidomide and dexamethasone for the treatment of newly diagnosed, transplant ineligible patients with multiple myeloma supported by the Phase 3 MAIA study, and Priority Review designation following submission of a supplemental BLA based on the Phase 3 CASSIOPEIA study, which is seeking approval of DARZALEX in combination with bortezomib, thalidomide and dexamethasone for newly diagnosed patients with multiple myeloma who are transplant eligible.

About the COLUMBA Study (MMY3012)1

The randomized, open-label, multicenter Phase 3 COLUMBA study included 522 patients with multiple myeloma who had received at least three prior lines of therapy including a proteasome inhibitor (PI) and an immunomodulatory drug (IMiD), or whose disease was refractory to both a PI and an IMiD (median age of 67). In the arm that received the SC formulation of DARZALEX (n=263), patients received a fixed dose of DARZALEX 1,800 milligrams (mg), co-formulated with recombinant human hyaluronidase PH20 (rHuPH20) 2,000 Units per milliliter (U/mL), subcutaneously weekly for Cycles 1 – 2, every two weeks for Cycles 3 – 6 and every four weeks for Cycle 7 and thereafter. In the DARZALEX IV arm (n=259), patients received DARZALEX for IV infusion 16 milligrams per kilogram (mg/kg) weekly for Cycles 1 – 2, every two weeks for Cycles 3 – 6 and every four weeks for Cycle 7 and thereafter. Each cycle was 28 days. In the arm that received the SC formulation, DARZALEX was given as a fixed volume over 3 – 5 minutes. In the arm that received the IV administration, the median durations of the first, second and subsequent DARZALEX IV infusions were 7.0, 4.3 and 3.4 hours, respectively. Patients in both treatment arms continued until disease progression or unacceptable toxicity.

About the PLEIADES Study (MMY2040)2

The non-randomized, open-label, parallel assignment Phase 2 PLEIADES study included 240 adults either newly diagnosed or with relapsed or refractory multiple myeloma. Patients with newly diagnosed multiple myeloma were treated with 1,800 mg of the SC formulation in combination with either bortezomib, lenalidomide and dexamethasone (D-VRd) or bortezomib, melphalan, and prednisone (D-VMP). Patients with relapsed or refractory disease were treated with 1,800 mg of the SC formulation plus lenalidomide and dexamethasone (D-Rd). The primary endpoint for the D-VMP and D-Rd cohorts was overall response rate. The primary endpoint for the D-VRd cohort was very good partial response or better rate. An additional cohort of patients with relapsed and refractory multiple myeloma treated with daratumumab plus carfilzomib and dexamethasone was subsequently added to the study.

About DARZALEX® (daratumumab)

DARZALEX® (daratumumab), the first CD38-directed antibody approved anywhere in the world, is the only CD38-directed antibody approved to treat multiple myeloma.3 CD38 is a surface protein that is present in high numbers on multiple myeloma cells, regardless of the stage of disease.4 DARZALEX binds to CD38 and inhibits tumor cell growth causing myeloma cell death.3 DARZALEX may also have an effect on normal cells.3 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.5,6,7,8,9,10,11,12 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.13,14

In the United States, DARZALEX received initial 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 and an immunomodulatory agent, or who are double refractory to a PI and an immunomodulatory agent.15DARZALEX 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.16 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.17 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.18 Most recently, in June 2019, DARZALEX was approved in combination with lenalidomide and dexamethasone for the treatment of patients with newly diagnosed multiple myeloma who are ineligible for ASCT.19 More than 80,000 patients have been treated with DARZALEX worldwide.

In August 2012, Janssen Biotech, Inc. entered into a global license and development agreement with Genmab A/S, which granted Janssen an exclusive license to develop, manufacture and commercialize DARZALEX.20 For the full U.S. Prescribing Information, please visit www.DARZALEX.com.

About Multiple Myeloma

Multiple myeloma is an incurable blood cancer that affects a type of white blood cell called plasma cells, which are found in the bone marrow.21,22 When damaged, these plasma cells rapidly spread and replace normal cells with tumors in the bone marrow.22,23 In 2019, it is estimated that more than 32,000 people will be diagnosed, and nearly 13,000 will die from the disease in the United States.23 While some patients with multiple myeloma have no symptoms, most patients are diagnosed due to symptoms, which can include bone fracture or pain, low red blood counts, tiredness, high calcium levels, kidney problems or infections.24

IMPORTANT SAFETY INFORMATION3

CONTRAINDICATIONS

DARZALEX® (daratumumab) 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 DARZALEX®. 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 and Thrombocytopenia – DARZALEX® may increase neutropenia and/or thrombocytopenia induced by background therapy. Monitor complete blood cell counts periodically during treatment according to the 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 and/or platelets. No dose reduction of DARZALEX® is recommended. Consider supportive care with growth factors for neutropenia or transfusions for thrombocytopenia.

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.
