Genmab A/S (Nasdaq: GMAB) announced today that the European Commission (EC) has granted marketing authorization for the daratumumab subcutaneous (SC) formulation (daratumumab and hyaluronidase-fihj), known as DARZALEX SC in the European Union, in combination with bortezomib, cyclophosphamide, and dexamethasone (VCd) for the treatment of adult patients with newly diagnosed systemic light-chain (AL) amyloidosis.
The EC also approved DARZALEX SC in combination with pomalidomide and dexamethasone (Pd) for the treatment of adult patients with multiple myeloma who have received one prior therapy containing a proteasome inhibitor (PI) and lenalidomide and were lenalidomide refractory, or who have received at least two prior therapies that included lenalidomide and a PI and have demonstrated disease progression on or after the last therapy. The approvals follow Positive Opinions by the CHMP of the European Medicines Agency in May 2021. In August 2012, Genmab granted Janssen Biotech, Inc. (Janssen) an exclusive worldwide license to develop, manufacture and commercialize daratumumab.
'AL amyloidosis is a potentially fatal blood disorder for which there is no cure, so we are extremely pleased that patients with AL amyloidosis in Europe may soon have a regimen including DARZALEX SC as a treatment option,' said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab. 'We are also pleased that, with the approval based on the APOLLO study, the combination of daratumumab with pomalidomide and dexamethasone will now be a treatment option for certain patients with relapsed or refractory multiple myeloma in Europe.'
About the ANDROMEDA (AMY3001) study
The Phase 3 study (NCT03201965) included 416 patients newly diagnosed with AL amyloidosis. Patients were randomized to receive treatment with either daratumumab and hyaluronidase-fihj in combination with bortezomib (a proteasome inhibitor), cyclophosphamide (a chemotherapy), and dexamethasone (a corticosteroid) or treatment with VCd alone. The primary endpoint of the study was the percentage of patients who achieve hematologic complete response.
About the APOLLO (MMY3013) study
The Phase 3 (NCT03180736), randomized, open-label, multicenter study included 304 patients with multiple myeloma who have previously been treated with lenalidomide and a PI. Patients were randomized 1:1 to either receive daratumumab in combination with Pd or Pd alone. In the original design of the study, patients in the daratumumab plus Pd arm were treated with the intravenous (IV) formulation of daratumumab. As of Amendment 1 to the study protocol, all new subjects in the experimental arm were dosed with the SC formulation of daratumumab and patients who had already begun treatment with IV daratumumab had the option to switch to the SC formulation. The primary endpoint of the study was progression free survival (PFS). The study was conducted in Europe under an agreement between Janssen, the European Myeloma Network (EMN) and Stichting Hemato-Oncologie voor Volwassenen Nederland (HOVON).
About AL Amyloidosis
Amyloidosis is a disease that occurs when amyloid proteins, which are abnormal proteins, accumulate in tissues and organs. When the amyloid proteins cluster together, they form deposits that damage the tissues and organs. AL amyloidosis most frequently affects the heart, kidneys, liver, nervous system and digestive tract. There is currently no cure for AL amyloidosis or existing approved therapies for AL amyloidosis patients in Europe, though it can be treated with chemotherapy, dexamethasone, stem cell transplants and supportive therapies.1 It is estimated that in 2019 there were 4,388 diagnosed incident cases of AL amyloidosis in the five major European markets.2
About Multiple Myeloma
Multiple myeloma is an incurable blood cancer that starts in the bone marrow and is characterized by an excess proliferation of plasma cells.3 Approximately 18,114 new patients were diagnosed with multiple myeloma and approximately 11,063 people died from the disease in the Western Europe in 2020.4 Globally, it was estimated that 176,404 people were diagnosed and 117,077 died from the disease in 2020.5 While some patients with multiple myeloma have no symptoms at all, most patients are diagnosed due to symptoms which can include bone problems, low blood counts, calcium elevation, kidney problems or infections.6
About DARZALEXSC (daratumumab and hyaluronidase-fihj)
Daratumumab is being developed by Janssen Biotech, Inc. under an exclusive worldwide license to develop, manufacture and commercialize daratumumab from Genmab. DARZALEX SC (daratumumab and hyaluronidase-fihj) is the first subcutaneous CD38 antibody approved in the Europe for the treatment of both multiple myeloma and AL amyloidosis. Daratumumab is a human IgG1k monoclonal antibody (mAb) that binds with high affinity to the CD38 molecule, which is highly expressed on the surface of multiple myeloma cells. Daratumumab triggers a person's own immune system to attack the cancer cells, resulting in rapid tumor cell death through multiple immune-mediated mechanisms of action and through immunomodulatory effects, in addition to direct tumor cell death, via apoptosis (programmed cell death). 7,8, 9, 10, 11
