SOMERSET, N.J.--(BUSINESS WIRE)-- Legend Biotech Corporation (NASDAQ: LEGN) ("Legend Biotech"), a global clinical-stage biopharmaceutical company engaged in the discovery and development of novel cell therapies for oncology and other indications, announced today the submission of a Marketing Authorisation Application (MAA) to the European Medicines Agency (EMA) seeking approval of ciltacabtagene autoleucel (cilta-cel) for the treatment of patients with relapsed and/or refractory multiple myeloma.
Cilta-cel is an investigational B-cell maturation antigen (BCMA)-directed chimeric antigen receptor T cell (CAR-T) therapy being investigated as a treatment for multiple myeloma. The MAA is based on positive results from a Phase 1b/2 CARTITUDE-1 study, which were presented at the American Society of Hematology (ASH) 2020 Annual Meeting.1The submission was filed to the EMA by Janssen-Cilag International N.V., an affiliate of Janssen Biotech, Inc., Legend's collaboration partner for cilta-cel.
"Today's submission is a testimony to the promising results we have seen from the CARTITUDE-1 study showing the efficacy and safety of cilta-cel for treating patients with multiple myeloma who are heavily pretreated and in need of treatment options," said Ying Huang, PhD, CEO and CFO of Legend Biotech. "We are proud of our collaboration with Janssen and look forward to bringing this personalized treatment to patients in the EU following the accelerated assessment."
The EMA's Committee for Medicinal Products for Human Use (CHMP) granted accelerated assessment for this MAA. An accelerated assessment is granted when the CHMP determines that a medicinal product is of major public health interest and therapeutic innovation and can significantly reduce the review timelines to evaluate an MAA.2 Cilta-cel previously received a PRIority MEdicines (PRIME) designation from the EMA. A Biologics License Application (BLA) seeking approval of cilta-cel based on the CARTITUDE-1 study is currently under review with the United States Food and Drug Administration.
CARTITUDE-1 (NCT03548207) is an ongoing Phase 1b/2, open-label, multicenter study evaluating the safety and efficacy of cilta-cel in adults with relapsed and/or refractory multiple myeloma, 99 percent of whom were refractory to the last line of treatment; 88 percent of whom were triple-class refractory (to at least 1 immunomodulatory drug [IMiD], proteasome inhibitor [PI] and 1 anti-CD38 antibody).3 The primary objective of the Phase 1b portion of the study was to characterize the safety and confirm the dose of cilta-cel, informed by the first-in-human study with LCAR-B38M CAR-T cells (LEGEND-2). The Phase 2 portion further evaluated the efficacy of cilta-cel with overall response rate as the primary endpoint.
About Ciltacabtagene autoleucel (cilta-cel)
Cilta-cel is an investigational chimeric antigen receptor T cell (CAR-T) therapy, formerly identified as JNJ-4528 outside of China and LCAR-B38M CAR-T cells in China, that is being studied in a comprehensive clinical development program for the treatment of patients with relapsed and/or refractory multiple myeloma and in earlier lines of treatment. Cilta-cel is a differentiated CAR-T therapy with two BCMA-targeting single domain antibodies. In December 2017, Legend Biotech, Inc. entered into an exclusive worldwide license and collaboration agreement with Janssen Biotech, Inc. to develop and commercialize cilta-cel. In addition to a Breakthrough Therapy Designation (BTD) granted in the U.S. in December 2019, cilta-cel received a BTD in China in August 2020. In addition, Orphan Drug Designation was granted for cilta-cel by the U.S. FDA in February 2019, and by the European Commission in February 2020.
About Multiple Myeloma
Multiple myeloma is an incurable blood cancer that starts in the bone marrow and is characterized by an excessive proliferation of plasma cells.4 Although treatment may result in remission, unfortunately, patients will most likely relapse.5 Relapsed myeloma is when the disease has returned after a period of initial, partial or complete remission and does not meet the definition of being refractory.6 Refractory multiple myeloma is when a patient's disease is non-responsive or progresses within 60 days of their last therapy.7,8 While some patients with multiple myeloma have no symptoms until later stages of the disease, most patients are diagnosed due to symptoms that can include bone problems, low blood counts, calcium elevation, kidney problems or infections.9 Patients who relapse after treatment with standard therapies, including protease inhibitors and immunomodulatory agents, have poor prognoses and few treatment options.10
