SOMERSET - Legend Biotech Corporation (NASDAQ: LEGN) (Legend Biotech), a global biotechnology company developing, manufacturing and commercializing novel therapies to treat life-threatening diseases, announced today that CARTITUDE-4, the Phase 3 study evaluating CARVYKTI (ciltacabtagene autoleucel; cilta-cel) for the treatment of adult patients with relapsed and lenalidomide-refractory multiple myeloma, met its primary endpoint of showing a statistically significant improvement in progression-free survival (PFS) compared to standard therapy at the study's first pre-specified interim analysis.
The study has been unblinded following the recommendation of an independent data monitoring committee.
The CARTITUDE-4 (NCT04181827) study is the first international, randomized, open-label Phase 3 study evaluating the efficacy and safety of a CAR-T therapy versus pomalidomide, bortezomib and dexamethasone (PVd) or daratumumab, pomalidomide and dexamethasone (DPd) in adult patients with relapsed and lenalidomide-refractory multiple myeloma who received one to three prior lines of therapy.
The primary endpoint of the study is PFS. Secondary endpoints include safety, overall survival (OS), minimal residual disease (MRD) negative rate and overall response rate (ORR). Patients will continue to be followed for primary and secondary endpoints as part of the CARTITUDE-4 study.
'Autologous CAR-T cell therapy represents a major breakthrough in cancer treatment, and topline results from CARTITUDE-4 support our continuous efforts to bring this treatment option to patients with multiple myeloma in various stages of disease progression,' Lida Pacaud, M.D., Vice President of Clinical Development and Medical Affairs at Legend Biotech, said.
Results from the CARTITUDE-4 study will be submitted to an upcoming medical meeting and will support discussions with health authorities about potential regulatory submissions.
CARVYKTI INDICATIONS AND USAGE
CARVYKTI (ciltacabtagene autoleucel) is a B-cell maturation antigen (BCMA)-directed genetically modified autologous T cell immunotherapy indicated for the treatment of adult patients with relapsed or refractory multiple myeloma, after four or more prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody.
ABOUT CARVYKTI (CILTACABTAGENE AUTOLEUCEL; CILTA-CEL)
Ciltacabtagene autoleucel is a BCMA-directed, genetically modified autologous T-cell immunotherapy, which involves reprogramming a patient's own T-cells with a transgene encoding a chimeric antigen receptor (CAR) that identifies and eliminates cells that express BCMA. BCMA is primarily expressed on the surface of malignant multiple myeloma B-lineage cells, as well as late-stage B-cells and plasma cells. The cilta-cel CAR protein features two BCMA-targeting single domain antibodies designed to confer high avidity against human BCMA. Upon binding to BCMA-expressing cells, the CAR promotes T-cell activation, expansion, and elimination of target cells.[1]
In December 2017, Legend Biotech entered into an exclusive worldwide license and collaboration agreement with Janssen Biotech, Inc. (Janssen) to develop and commercialize cilta-cel.
In February 2022, cilta-cel was approved by the U.S. Food and Drug Administration (FDA) under the brand name CARVYKTI for the treatment of adults with relapsed or refractory multiple myeloma.[2] In May 2022, the European Commission (EC) granted conditional marketing authorization of CARVYKTI for the treatment of adults with relapsed and refractory multiple myeloma.[3] In September 2022, Japan's Ministry of Health, Labour and Welfare (MHLW) approved CARVYKTI.[4] Cilta-cel was granted Breakthrough Therapy Designation in the U.S. in December 2019 and in China in August 2020. In addition, cilta-cel received a PRIority MEdicines (PRIME) designation from the European Commission in April 2019. Cilta-cel also received Orphan Drug Designation from the U.S. FDA in February 2019, from the European Commission in February 2020, and from the Pharmaceuticals and Medicinal Devices Agency (PMDA) in Japan in June 2020. In March 2022, the European Medicines Agency's Committee for Orphan Medicinal Products recommended by consensus that the orphan designation for cilta-cel be maintained on the basis of clinical data demonstrating improved and sustained complete response rates following treatment.[5]
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.[6] In 2023, it is estimated that more than 35,000 people will be diagnosed with multiple myeloma, and more than 12,000 people will die from the disease in the U.S[7] While some patients with multiple myeloma have no symptoms at all, most patients are diagnosed due to symptoms that can include bone problems, low blood counts, calcium elevation, kidney problems or infections.[8] Although treatment may result in remission, unfortunately, patients will most likely relapse.[9] Patients who relapse after treatment with standard therapies, including protease inhibitors, immunomodulatory agents, and an anti-CD38 monoclonal antibody, have poor prognoses and few treatment options available.[10],[11]
