SAN DIEGO, Jan. 15, 2021 /PRNewswire/ — Halozyme Therapeutics, Inc. (NASDAQ: HALO) today announced that Janssen Biotech, Inc. (Janssen) has received U.S. Food and Drug Administration (FDA) approval of DARZALEX FASPRO® (daratumumab and hyaluronidase-fihj) in combination with bortezomib, cyclophosphamide and dexamethasone (D-VCd) for the treatment of adult patients with newly diagnosed light chain (AL) amyloidosis.1 DARZALEX FASPRO® is the first and only FDA-approved treatment for patients with this rare and serious blood disorder associated with the production of an abnormal protein which leads to the deterioration of vital organs, most notably the heart, kidneys and liver.1 This indication is approved under accelerated approval and is based on the combination’s hematologic complete response rate (hemCR) measure. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial. DARZALEX FASPRO® is not indicated and is not recommended for the treatment of patients with light chain (AL) amyloidosis who have NYHA Class IIIB or Class IV cardiac disease or Mayo Stage IIIB outside of controlled clinical trials.
“We are delighted that DARZALEX FASPRO® utilizing our ENHANZE® technology has become the first and only FDA-approved treatment for newly diagnosed patients with AL amyloidosis,” said Dr. Helen Torley, president and chief executive officer. “AL amyloidosis represents an area of high unmet medical need.”
The FDA approval is based on positive results from the Phase 3 ANDROMEDA study, which were recently presented at the American Society of Hematology (ASH) 2020 Annual Meeting. The study evaluated DARZALEX FASPRO® in combination with VCd, compared with VCd alone, a common treatment regimen offered to adult patients with newly diagnosed AL amyloidosis. 5 Patients receiving treatment with DARZALEX FASPRO® experienced a hemCR more than triple that of patients receiving VCd alone (42 percent for D-VCd and 13 percent for VCd; P<0.0001).1
Approximately 4,500 people in the U.S. develop this rare disease each year.4 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.3 The disease can affect different organs in different people, but the most frequently affected organs are the heart, kidneys, liver, spleen, gastrointestinal tract and nervous system.2,3 About one-third of patients visit five or more doctors before receiving a diagnosis, and 72 percent are diagnosed more than one year after they first experience symptoms.3,4 Patients often have a poor prognosis due to the delay in diagnosis of AL amyloidosis, which frequently presents with non-specific symptoms that can mimic other, more common conditions.6 As many as 30 percent of patients with AL amyloidosis die within the first year after diagnosis.7
