*JNJ-4528 identifies the investigational product being studied in the US/EU and LCAR -B38M identifies the investigational product in China, both of which are representative of the same CAR-T cell therapy.
Piscataway, NJ, November 6, 2019 – Legend Biotech today announced data from the Janssen Research & Development, LLC (Janssen) CARTITUDE-1 study (US) and the LEGEND-2 study (China) will be presented during the 61st American Society of Hematology (ASH) Annual meeting in Orlando, Florida taking place December 7-10, 2019.
"The data presentations at ASH 2019 represent two key milestones; the initial data from CARTITUDE-1 study in the US and the long term follow-up for the LEGEND-2 study in China," stated Yuan Xu, PhD, CEO of Legend Biotech. "In collaboration with Janssen, we are committed to the clinical development of LCAR-B38M/JNJ-4528 and are working diligently together to bring this investigational therapy to patients with multiple myeloma."
On Monday, December 9th during the Myeloma session titled: Therapy, excluding Transplantation: Novelty in CAR-T in RRMM, the first clinical data from the CARTITUDE-1 study will be presented. In the same session, long-term follow-up data from the previously reported LEGEND-2 study in China for the 57 patients enrolled at the Second Affiliated Hospital of Xi'an Jiaotong University will be presented, with updated data.
Additionally, updated results for the 17 patients enrolled in the LEGEND-2 study at the Shanghai Ruijin Hospital, Shanghai Changzheng Hospital, and Jiangsu Province People's Hospital will be presented by the investigators.
Abstracts will be presented during the following dates and times:

In February 2019, the US Food and Drug Administration granted Janssen an Orphan Drug Designation for JNJ-4528. On April 3, 2019, Legend announced that the European Medicines Agency (EMA) granted Janssen a PRIME1 designation for JNJ-4528, which was supported by results from the Phase 1b/2 CARTITUDE-1 study (NCT03548207)2 and the Phase 1/2 LEGEND-2 study (NCT03090659)3 evaluating LCAR-B38M in RRMM.
LEGEND-2 (NCT03090659) is an ongoing single-arm, open-label Phase 1/2 study of 74 patients being conducted at four participating hospitals in China evaluating the efficacy and safety of LCAR-B38M for the treatment of relapsed or refractory multiple myeloma.
In China, the Phase 2 CARTIFAN-1 (MMY2002, NCT03758417)4 confirmatory trial registered with the Center for Drug Evaluation (CTR20181007), is actively recruiting to further evaluate LCAR - B38M in patients with advanced relapsed or refractory multiple myeloma.
In the US, JNJ-4528 is currently being investigated in the Phase 1b/2 CARTITUDE-1 (MMY2001, NCT03548207) registration study 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.
In the global, multi-cohort Phase 2 CARTITUDE-2 (MMY2003, NCT04133636)5 study, JNJ-4528 will be investigated in patients with multiple myeloma in various clinical settings. This study is being conducted to evaluate the overall minimal residual disease (MRD) negative rate of participants who receive JNJ-4528.
In the US and EU, a prospective observational study LocoMMotion (MMY4001, NCT04035226)6 is being conducted to evaluate current real-world standards of care in patients with RRMM who received at least 3 prior lines of therapy including a PI, an IMiD, and anti-CD38 antibody. The abstract will be published in Blood.
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.7 Although treatment may result in remission, unfortunately, patients will most likely relapse.8 Refractory multiple myeloma is when a patient’s disease is non-responsive or progresses within 60 days of their last therapy.9,10 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.11 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.12 Patients who relapse after treatment with standard therapies, including protease inhibitors and immunomodulatory agents, have poor prognoses and few treatment options available.13
