We are optimistic that we will navigate and overcome the challenges ahead with resilience and determination, advancing our innovative cell therapies."

Zevorcabtagene autoleucel (CT053) is an autologous fully human CAR T-cell product candidate against B-cell maturation antigen (BCMA) for the treatment of relapsed/refractory multiple myeloma (R/R MM). As informed by the NMPA on March 1, 2024, zevorcabtagene autoleucel was granted conditional approval on February 23, 2024 for the treatment of adult patients with relapsed or refractory multiple myeloma who have progressed after at least 3 prior lines of therapy (including a proteasome inhibitor and an immunomodulatory agent). An update from the Phase I study in China (NCT03975907) with 3-year follow-up was presented as a poster at the 2023 American Society of Hematology ("ASH") Annual Meeting in December 2023.

Satricabtagene autoleucel (CT041) is an autologous humanized CAR T-cell product candidate against Claudin18.2 (CLDN18.2), a membrane protein highly expressed in certain cancers. As of the date of the announcement, satricabtagene autoleucel, based on our information, is the world's first CAR T-cell candidate for the treatment of solid tumors entering a Phase II clinical trial. In April 2023, satricabtagene autoleucel IND was approved by the National Medical Products Administration (NMPA) for the postoperative adjuvant therapy of Claudin18.2 positive pancreatic cancer (PC) (CT041-ST-05, NCT05911217). In May 2023, the Phase 2 part of the Phase 1b/2 clinical trial (NCT04404595) in the U.S. and Canada was initiated for the treatment of Claudin18.2 positive advanced gastric cancer/gastroesophageal junction cancer (GC/GEJ) in patients who have failed at least 2 prior lines of systemic therapies. Updates from the Phase 1b study in the U.S. (NCT04404595) were presented as a poster at the 2024 American Society of Clinical Oncology Gastrointestinal Cancers Symposium ("ASCO GI").

CT011 is an autologous CAR T-cell product candidate against Glypican-3 (GPC3). In January 2024, CT011 IND was approved by the NMPA for GPC3-positive stage IIIa hepatocellular carcinoma at high risk of recurrence after surgical resection.

In July 2023, an article titled "Combined local therapy and CAR-GPC3 T-cell therapy in advanced hepatocellular carcinoma: a proof-of-concept treatment strategy" was published in Cancer Communication (London, England) demonstrating patients who received local therapy followed by sequential infusions of CAR-GPC3 T-cells achieved more than 7-year disease-free survival.

CT071 is an autologous fully human CAR T-cell therapy candidate against G protein-coupled receptor class C group 5 member D (GPRC5D) developed utilizing CARsgen's proprietary CARcelerate^TM platform for the treatment of R/R MM and relapsed/refractory primary plasma cell leukemia (R/R pPCL). The IND was cleared by the FDA on November 30, 2023 for R/R MM and R/R pPCL. An investigator-initiated trial (IIT) is ongoing in China to assess the safety and efficacy of CT071 in treating R/R MM and relapsed/refractory plasma cell leukemia (R/R PCL) (NCT05838131).

In January 2023, CARsgen and Huadong Medicine (Hangzhou) Co., Ltd., a wholly-owned subsidiary of Huadong Medicine Co., Ltd. (SZ. 000963) entered into a collaboration agreement for the commercialization of zevorcabtagene autoleucel, in mainland China.

In August 2023, CARsgen and Moderna, Inc. (Nasdaq: MRNA, "Moderna") have initiated a collaboration agreement to investigate satricabtagene autoleucel in combination with Moderna's investigational Claudin18.2 mRNA cancer vaccine.
