CARVYKTI^® (ciltacabtagene autoleucel) Receives Positive CHMP Opinion for the Treatment of Patients with Relapsed and Refractory Multiple Myeloma

Ciltacabtagene autoleucel, if approved by the European Commission (EC), will be Legend Biotech’s first EC-approved product

SOMERSET, N.J.--(BUSINESS WIRE)--March 25, 2022--Legend Biotech Corporation (NASDAQ: LEGN) (Legend Biotech), a global biotechnology company developing, manufacturing and commercializing novel therapies to treat life-threatening diseases, today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) recommended Janssen Pharmaceutica NV’s marketing authorization of CARVYKTI^® (ciltacabtagene autoleucel; cilta-cel) for the treatment of adults with relapsed and refractory multiple myeloma who have received at least three prior therapies, including an immunomodulatory agent, a proteasome inhibitor and an anti-CD38 antibody and have demonstrated disease progression on the last therapy.

Cilta-cel is a chimeric antigen receptor T-cell (CAR-T) therapy featuring two B-cell maturation antigen (BCMA)-targeting single domain antibodies.¹ CAR-T therapy is a highly personalized technology where a person’s own T-cells are engineered to target and kill cancer cells in a single infusion.²

Data from the ongoing pivotal CARTITUDE-1 study supported the positive CHMP opinion. Two-year follow-up results were presented at the American Society of Hematology (ASH) 2021 Annual Meeting (Abstract #549).¹

“The positive CHMP opinion reinforces the potential of cilta-cel for patients with multiple myeloma around the world,” said Ying Huang, Ph.D., Chief Executive Officer and Chief Financial Officer of Legend Biotech. “We look forward to the EMA to the potential of European Commission approval in the future and continued progress in the development of cilta-cel.”

Multiple myeloma is an incurable blood cancer affecting a type of white blood cell called plasma cells, which are found in the bone marrow.³ The majority of patients relapse after undergoing initial treatment and face poor prognoses after treatment with three major drug classes, including an immunomodulatory agent, a proteasome inhibitor and anti-CD38 monoclonal antibody.^4,5,6

This CHMP Opinion follows the approval of cilta-cel by the U.S. Food and Drug Administration (FDA) on February 28, 2022.

About Ciltacabtagene autoleucel (cilta-cel)

Cilta-cel 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.

In December 2017, Legend Biotech Corporation entered into an exclusive worldwide license and collaboration agreement with Janssen Biotech, Inc. to develop and commercialize cilta-cel.

In April 2021, Legend announced the submission of a Marketing Authorisation Application to the European Medicines Agency seeking approval of cilta-cel for the treatment of patients with relapsed and/or refractory multiple myeloma. In addition to U.S. Breakthrough Therapy Designation granted in December 2019, cilta-cel received a Breakthrough Therapy Designation in China in August 2020. Cilta-cel also received Orphan Drug Designation from the U.S. FDA in February 2019, and from 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.3 In Europe, it is estimated that more than 50,900 people were diagnosed with multiple myeloma in 2020, and approximately 32,500 multiple myeloma patients died that year.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.⁴ 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.^5,6
