DARZALEX(R) (daratumumab) Combination Regimen Significantly Improved Outcomes for Newly Diagnosed Multiple Myeloma Patients who are Transplant IneligiblePhase 3 ALCYONE data showed DARZALEX in combination with bortezomib, melphalan and prednisone meaningfully improved progression-free survival and response rates
Data featured as late-breaker at ASH 2017 (Abstract #LBA-4) and published in the New England Journal of Medicine
ATLANTA and RARITAN, N.J., Dec. 12, 2017 -- (Healthcare Sales & Marketing Network) -- Janssen Research & Development, LLC today announced data from the Phase 3 ALCYONE study, showing that DARZALEX® (daratumumab) in combination with bortezomib, melphalan and prednisone (VMP) significantly improved clinical outcomes, including reducing the risk of disease progression or death by 50 percent, in patients with newly diagnosed multiple myeloma who are ineligible for autologous stem cell transplantation (ASCT).1 These data were presented as a late-breaking abstract today at the 59th American Society of Hematology (ASH) Annual Meeting in Atlanta (Abstract #LBA-4). Study findings were simultaneously published in the New England Journal of Medicine.
"These Phase 3 results for DARZALEX demonstrated clinically meaningful improvements with a manageable safety profile," said Dr. Maria-Victoria Mateos, Ph.D., lead ALCYONE study investigator and Director of the Myeloma Unit at University Hospital of Salamanca-IBSAL, Salamanca, Spain. "Selecting the right treatment regimen is critical for patients who are newly diagnosed, especially if they are transplant ineligible, as these patients tend to be older and more frail. These findings strongly support this DARZALEX frontline regimen as a new standard of care for these patients."
At a median follow-up of 16.5 months, DARZALEX-VMP reduced the risk of disease progression or death by 50 percent, compared to treatment with VMP alone (Hazard Ratio [HR] = 0.50; 95 percent CI [0.38-0.65], p<0.0001).1 The median progression-free survival (PFS) for DARZALEX-VMP had not yet been reached, compared to an estimated median PFS of 18.1 months for patients who received VMP alone.1
In addition to reducing the risk of disease progression or death, DARZALEX significantly improved overall response rates (ORR) (91 percent vs. 74 percent) compared to VMP alone, including more than doubling rates of stringent complete response (sCR) (18 percent vs. 7 percent) and significantly improving rates of very good partial response (VGPR) or better (71 percent vs. 50 percent) and complete response (CR) or better (43 percent vs. 24 percent).1 Patients receiving DARZALEX also reported a more than three-fold increase in the minimal residual disease (MRD) negativity rate (22 percent vs. 6 percent) compared to those who received VMP alone.1
The most common (≥10 percent) Grade 3/4 treatment-emergent adverse events (TEAEs) for DARZALEX-VMP vs. VMP were neutropenia (40 percent vs. 39 percent), thrombocytopenia (34 percent vs. 38 percent), anemia (16 percent vs. 20 percent) and pneumonia (11 percent vs. 4 percent).1 One patient in each arm discontinued treatment due to pneumonia, and 0.9 percent of patients discontinued DARZALEX due to an infection.1 Twenty-eight percent of patients experienced infusion reactions (IRs) due to DARZALEX.1 In the DARZALEX-VMP arm, 42 percent of patients experienced a serious adverse event (SAE), compared to 33 percent in the VMP arm.1 The most common (≥2 percent) SAEs were pneumonia (10 percent vs. 3 percent), anemia (2 percent vs. 3 percent), bronchitis (2 percent vs. 1 percent), lower respiratory tract infection (2 percent vs. 1 percent), upper respiratory tract infection (2 percent vs. 1 percent), febrile neutropenia (1 percent vs. 2 percent) and cardiac failure (<1 percent vs. 2 percent) for DARZALEX-VMP vs. VMP, respectively.1
"DARZALEX offers compelling and consistent clinical benefit across all lines of therapy in multiple myeloma," said Sen Zhuang, M.D. Ph.D., Vice President, Oncology Clinical Research, Janssen Research & Development. "These latest results convey the promise of DARZALEX in newly diagnosed patients for whom the initial therapy is most critical for long-term survival."
On November 21, 2017, Janssen submitted a supplemental Biologics License Application (sBLA) to the U.S. Food and Drug Administration (FDA) for DARZALEX in combination with VMP for this patient population. Janssen requested Priority Review of this sBLA, which would shorten FDA review to six months, compared to 10 months for Standard Review. If approved, this would be the fifth indication for DARZALEX in the U.S. and its first in the frontline setting. On November 21, 2017, Janssen also submitted an application for this patient population to the European Medicines Agency.
About the ALCYONE Trial1
The randomized, open-label, multicenter Phase 3 ALCYONE (MMY3007) study enrolled 706 newly diagnosed patients with multiple myeloma who were ineligible for high-dose chemotherapy with ASCT. In the DARZALEX-VMP arm, the median age was 71 years (range: 40-93), 30 percent were ≥75 years and 46 percent were male. Patients were randomized to receive nine cycles of either DARZALEX combined with VMP, or VMP alone. In the DARZALEX-VMP arm, patients received 16 mg/kg of DARZALEX once weekly for six weeks (Cycle 1; 1 Cycle = 42 days), followed by once every three weeks (Cycles 2-9). Following the nine cycles, patients in the DARZALEX-VMP arm continued to receive 16 mg/kg of DARZALEX once every four weeks until disease progression.
About DARZALEX® (daratumumab) Injection, for Intravenous Infusion
DARZALEX® (daratumumab) injection for intravenous use is the first CD38-directed antibody approved anywhere in the world.2 CD38 is a surface protein that is highly expressed across multiple myeloma cells.3 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.2 A subset of myeloid derived suppressor cells (MDSCs), CD38+ regulatory T cells (Tregs) and CD38+ B cells (Bregs) were decreased by DARZALEX.2 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.4,5,6,7,8 Additional studies are ongoing or planned to assess its potential for a solid tumor indication and in other malignant and pre-malignant diseases in which CD38 is expressed, such as smoldering myeloma.9,10,11 DARZALEX was the first CD38-directed antibody to receive regulatory approval to treat relapsed or refractory multiple myeloma.2
In August 2012, Janssen Biotech, Inc. and Genmab A/S entered a worldwide agreement, which granted Janssen an exclusive license to develop, manufacture and commercialize DARZALEX.12 DARZALEX is commercialized in the U.S. by Janssen Biotech, Inc.12 For more information, visit www.DARZALEX.com.
About Multiple Myeloma
Multiple myeloma is an incurable blood cancer that occurs when malignant plasma cells grow uncontrollably in the bone marrow.13,14 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.15,16 Relapsed cancer means the disease has returned after a period of initial, partial or complete remission.17 It is estimated that 30,280 people will be diagnosed and 12,590 will die from the disease in the United States in 2017.18 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.19
IMPORTANT SAFETY INFORMATION
CONTRAINDICATIONS - None
WARNINGS AND PRECAUTIONS
Infusion Reactions – DARZALEX can cause severe infusion reactions. Approximately half of all patients experienced a reaction, most during the first infusion. 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 for life-threatening (Grade 4) reactions. 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.
