CARTITUDE-1 data for oral presentation will highlight Phase 1b/2 efficacy and safety results for the B-cell maturation antigen (BCMA)-targeted chimeric antigen receptor T cell (CAR-T) therapy ciltacabtagene autoleucel (cilta-cel). Additional poster presentations for cilta-cel data will include detailed analyses of cytokine release syndrome and health-related quality of life outcomes from CARTITUDE-1. LEGEND-2 data in patients with relapsed or refractory multiple myeloma and extramedullary disease will also be presented as a poster.

"We look forward to sharing new data from the CARTITUDE-1 study in the US and the LEGEND-2 study in China," said Ying Huang, PhD, interim-CEO and CFO of Legend Biotech. "With our successful clinical efforts and the Company’s collaboration with Janssen, we are uniquely positioned to deliver a novel therapy to patients with multiple myeloma."

On Saturday, December 5th, during the Myeloma session entitled: Myeloma/Amyloidosis: Therapy, excluding Transplantation: Novel Therapies Targeting B Cell Maturation Antigen in Relapsed/Refractory Multiple Myeloma, the Phase 1b/2 clinical efficacy and safety data for cilta-cel from the CARTITUDE-1 study will be presented.

Following are details of the five abstracts that have been accepted for presentation at the 62nd ASH (Free ASH Whitepaper) Annual Meeting & Exposition. For additional information visit: View Source

About CARTITUDE-1
Cilta-cel is currently being investigated in the Phase 1b/2 CARTITUDE-1 (MMY2001, NCT03548207) registration study conducted in the US and Japan for the treatment of patients with multiple myeloma who have received at least 3 prior lines of therapy or are double refractory to a PI and IMiD, received a PI, an IMiD, and anti-CD38 antibody and documented disease progression within 12 months of starting the most recent therapy.1

About LEGEND-2
LEGEND-2 (NCT03090659) is an ongoing single-arm, open-label Phase 1 study of 74 patients being conducted at four participating hospitals in China evaluating the efficacy and safety of LCAR-B38M CAR-T cells for the treatment of relapsed or refractory multiple myeloma.2

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.3 Although treatment may result in remission, unfortunately, patients will most likely relapse.4 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.5 Refractory multiple myeloma is when a patient’s disease is non-responsive or progresses within 60 days of their last therapy.6,7 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 Patients who relapse after treatment with standard therapies, including protease inhibitors and immunomodulatory agents, have poor prognoses and few treatment options available.9

About Cilta-cel
Cilta-cel is an investigational chimeric antigen receptor T cell (CAR-T) therapy, formerly identified as JNJ-4528 in the U.S. and Europe 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 or refractory multiple myeloma and in earlier lines of treatment. The design consists of a structurally differentiated CAR-T 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. (Janssen) 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 PRIority MEdicines (PRiME) designation from the European Commission in April 2019, and 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.
