According to the latest public announcement made today by the Center for Drug Evaluation (CDE) of China’s National Medical Products Administration, the clinical trial application (acceptance number: JXSL1900121) for the CAR-T cell therapy CTL019 submitted by Novartis has received implicit approval for clinical trials. The indication is:Long-term Follow-up of Patients Exposed to Lentiviral-based CAR-T Cell TherapyNotably,CTL019 is a breakthrough CAR-T novel drug under Novartis and the first CAR-T therapy approved by the U.S. FDA

CTL019 (tisagenlecleucel) is a genetically engineered autologous T-cell immunotherapy. The treatment process begins with the extraction of T cells from the patient, followed by genetic modification at a manufacturing center. These T cells are engineered to express a novel chimeric antigen receptor (CAR), enabling them to directly target and destroy leukemia cells bearing the CD19 antigen. Once modified, the T cells are infused back into the patient for therapeutic purposes.

As the world’s first CAR-T therapy, CTL019 can be said to have ushered in a new chapter in cancer immunotherapy. It once received from the U.S. FDABreakthrough Therapy Designation, Priority Review Status, and Fast Track Designation

CTL019 originated at the University of Pennsylvania. In 2012, Novartis entered into a global collaboration agreement with the University of Pennsylvania to jointly research, develop, and commercialize multiple CAR-T therapies, including CTL019. In the following years, Novartis successively released clinical data on this therapy, demonstrating its efficacy and safety in pediatric and young adult patients with relapsed/refractory acute lymphoblastic leukemia (r/r ALL). Years of investment and effort ultimately bore fruit. In July 2017, the FDA’s Oncologic Drugs Advisory Committee (ODAC) convened an evaluation meeting for Novartis’ CAR-T therapy CTL019,Unanimously recommended for approval with a 10-0 vote.

August 2017,United StatesThe FDA has officially approved the therapy for market launch.For the treatment of relapsed or refractory B-cell acute lymphoblastic leukemia in children and adolescents, marketed under the brand name Kymriah. The safety and efficacy of this therapy were validated in a multicenter clinical trial. The study enrolled 63 children and young adults with refractory or relapsed B-cell precursor acute lymphoblastic leukemia (ALL).Within 3 months of treatment, the overall response rate achieved with CAR-T therapy was 83%.. However, it may also cause side effects such as cytokine storm and neurological events. Weighing the benefits against the risks, the U.S. FDA ultimately decided to approve its marketing authorization, bringing new hope for treatment to specific patient populations.
Based on the Phase 2 clinical study named “JULIET,” the FDA approved Kymriah in May 2018 for the treatment of adult patients with relapsed or refractory large B-cell lymphoma (LBCL). In this study, 106 patients received Kymriah infusion, and the results showed that,The overall response rate (ORR) in adult patients with relapsed or refractory DLBCL treated with Kymriah was 50%, with a complete response (CR) rate of 32% and a partial response rate of 18%.
In China, Novartis' CTL019Clinical trial approval was granted in late October 2019 (JXSL1900067), for the indication of relapsed or refractory aggressive B-cell non-Hodgkin lymphoma.. This is the first clinical trial project approved in China for this star therapy. This marks the second clinical study approved in China for CTL019.
