DARZALEX? SC Becomes the First and Only Health Canada-Approved Treatment for Patients with Newly Diagnosed Light Chain (AL) Amyloidosis, A Rare Disease

TORONTO,?April 19, 2021?/CNW/ -?The Janssen Pharmaceutical Companies of Johnson & Johnson announced today Health Canada approved DARZALEX??SC (daratumumab?injection), a subcutaneous (SC) formulation of daratumumab, in combination with bortezomib, cyclophosphamide and dexamethasone (D-VCd, also known as DCyBorD) for the treatment of adult patients with newly diagnosed light chain (AL) amyloidosis.1?The DARZALEX??SC combination regimen?is the first and only Health Canada approved treatment for patients with AL amyloidosis,2?a rare blood cell disorder with no cure.3?AL amyloidosis occurs when an abnormal protein produced in the bone marrow is deposited and builds up in vital organs like the heart and kidneys, impacting their ability to function.4 "AL amyloidosis is rare and can present differently from person to person, yet many patients experience organ deterioration or failure by the time they are diagnosed. I hope this approval can lead to greater awareness of this disease and the importance of early diagnosis and treatment," says Dr.?Victor Zepeda, Assistant Professor of Medicine at?University of Calgary?and Clinician Scientist at the Arnie Charbonneau Cancer Institute.**?"Patients with this disease have extremely limited options, and today's approval of this subcutaneous formulation of daratumumab offers new hope for those with AL amyloidosis and their caregivers." The Health Canada approval is based on positive results from the Phase 3 ANDROMEDA (AMY3001) study, which were presented at the European Hematology Association (EHA) 2020 Annual Congress. The study evaluated DARZALEX??SC in combination?with VCd, compared with VCd alone, a common treatment regimen used in adult patients with newly diagnosed AL amyloidosis.5?Patients receiving treatment with D-VCd experienced?a hematologic complete response rate (hemCR) nearly triple that of patients receiving VCd alone (53 per cent for D-VCd and 18 per cent for VCd;?P<0.0001).6 AL amyloidosis is a life-threatening blood cell disorder that occurs when blood plasma cells in the bone marrow produce amyloid deposits, which build up in vital organs and eventually cause organ deterioration.7?The disease can affect different organs in different people, but the most frequently affected organs are the heart, kidneys, liver, gastrointestinal tract and nervous system.8,9 About one-third of patients with AL amyloidosis visit five or more doctors before receiving a diagnosis, and 72 per cent are diagnosed more than one year after experiencing first symptoms.10,11?Patients often have a poor prognosis due to the delay in diagnosis, which frequently presents with non-specific symptoms that can mimic other, more common conditions.12?As many as 30 per cent of patients with AL amyloidosis die within the first year after diagnosis.13 "We look forward to the potential of helping patients with AL amyloidosis who, until now, had no approved therapies for the treatment of their disease," said?Craig Tendler, M.D., Vice President, Late Development and Global Medical Affairs, Janssen Research & Development, LLC. "This approval underscores our continued commitment to deliver innovative therapies, which improve the outcomes for patients diagnosed with plasma cell diseases such as AL amyloidosis." The Health Canada review was conducted under Project Orbis, an initiative of the US FDA Oncology Center of Excellence, which provides a framework for concurrent submission and review of oncology medicine applications among international regulatory agencies, including Health Canada. Janssen looks forward to working with insurers to determine how the DARZALEX??SC combination regimen can be made accessible for newly diagnosed patients with AL amyloidosis through both private and public insurance plans. About the ANDROMEDA Study
ANDROMEDA (AMY3001) is an ongoing Phase 3, randomized, open-label study investigating the safety and efficacy of DARZALEX??SC in combination with bortezomib, cyclophosphamide and dexamethasone (D-VCd), compared to VCd alone, for the treatment of adult patients with newly diagnosed light chain (AL) amyloidosis.14?The study includes 388 patients with newly diagnosed AL amyloidosis with measurable hematologic disease and one or more organs affected.15?The primary endpoint is overall complete hematologic response rate by intent-to-treat (ITT).16?Patients received DARZALEX??SC 1,800?mg administered subcutaneously once weekly from weeks?1 to 8, once every 2?weeks from weeks?9 to 24 and once every 4?weeks starting with week?25 until disease progression or unacceptable toxicity or a maximum of 2?years.17?Among patients who received D-VCd, 74 per cent were exposed for 6?months or longer and 32 per cent were exposed for greater than one year.18 The most common treatment-emergent adverse events (=20 per cent) in the D-VCd arm were peripheral edema, fatigue, diarrhea, constipation, nausea, upper respiratory tract infection, peripheral sensory neuropathy, dyspnea, cough, insomnia, and anemia.?19?Serious treatment-emergent adverse events occurred in 43 per cent of patients in the D-VCd arm. Serious treatment-emergent adverse events that occurred in at least 5 per cent of patients in the D?VCd arm were pneumonia (7 per cent) and cardiac failure (7 per cent).?20?Fatal adverse reactions occurred in 11 per cent of patients in the D-VCd arm.?21?Fatal adverse reactions that occurred in more than one patient included cardiac arrest, sudden death, and cardiac failure (3 per cent respectively), and sepsis (1 per cent).22 About DARZALEX??SC DARZALEX??is the first CD38-directed monoclonal antibody (mAb) approved to treat multiple myeloma.23?In 2020, DARZALEX??SC became the only subcutaneously administered CD38-directed antibody approved to treat patients with multiple myeloma.24?And now, DARZALEX??SC in combination with bortezomib, cyclophosphamide and dexamethasone?is the first and only Health Canada approved treatment for patients with AL amyloidosis.?25?The safety and efficacy of DARZALEX??SC have not been established in AL amyloidosis patients with advanced cardiac disease (Mayo Stage IIIB or NYHA Class IIIB or IV).26 Daratumumab binds to CD38,?a surface protein highly expressed across clonal plasma cells that cause serious conditions such as multiple myeloma and AL amyloidosis.27?Daratumumab induces tumor cell death through cell lysis via multiple immune-mediated mechanisms of action, including complement-dependent cytotoxicity (CDC), antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP).28?Daratumumab?has also demonstrated immunomodulatory effects such as increasing CD4+ and CD8+ T-cells counts, which may contribute to clinical response.29 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?. Janssen Inc. commercializes DARZALEX??and DARZALEX??SC?in?Canada. For full Prescribing Information and more information about DARZALEX??SC,?please visit?www.janssen.com/canada.??
