CARsgen Presents Research Results on Satri-cel in The Lancet and at the 2025 ASCO Annual Meeting
SHANGHAI, June 1, 2025 /PRNewswire/ -- CARsgen Therapeutics Holdings Limited (Stock Code: a company focused on developing innovative CAR T-cell therapies, announces that the results of the pivotal Phase II clinical trial in China (CT041-ST-01, NCT04581473) investigating satricabtagene autoleucel ('satri-cel', CT041) (a Claudin18.2-specific autologous CAR T-cell product candidate) in patients with Claudin18.2-positive, advanced gastric/gastroesophageal junction cancer refractory to at least two prior lines of treatment, have been published in The Lancet and were orally presented at the 2025 ASCO Annual Meeting. Further details have been posted on the corporate website The article in The Lancet was titled 'Claudin-18 isoform 2-specific CAR T-cell therapy (satri-cel) versus treatment of physician's choice for previously treated advanced gastric or gastro-oesophageal junction cancer (CT041-ST-01): a randomised, open-label, phase 2 trial'. Full article available at: The oral presentation at the 2025 ASCO Annual Meeting (Abstract 4003) was titled 'Claudin18.2-specific CAR T cells (Satri-cel) versus treatment of physician's choice (TPC) for previously treated advanced gastric or gastroesophageal junction cancer (G/GEJC): Primary results from a randomized, open-label, phase II trial (CT041-ST-01)'. Professor Lin Shen from Beijing Cancer Hospital, the principal investigator of this study, said, 'The CT041-ST-01 trial represents the world's first randomized controlled clinical study of CAR-T cell therapy for solid tumors. In patients with heavily pretreated, advanced gastric/gastroesophageal junction cancer who have extremely limited treatment options and poor prognosis, satri-cel has demonstrated breakthrough efficacy with significant clinical benefits, including much improved progression-free survival (PFS), overall survival (OS), and tumor response rates. This brings new hope to patients with otherwise medically untreatable conditions. We are further exploring satri-cel's potential in adjuvant settings and as first-line sequential therapies, aiming to intervene earlier in the disease course, extend patients' survival, and ultimately pursue potential cures.' Dr. Zonghai Li, Founder, Chairman of the Board, Chief Executive Officer, and Chief Scientific Officer of CARsgen Therapeutics, said, 'We are honored that the CT041-ST-01 study results were published in The Lancet—a premier, global medical journal—and presented at the 2025 ASCO Annual Meeting. The positive result of this randomized controlled trial marks a major milestone in solid tumor CAR-T therapy. These achievements are a testament to the whole research team's years of dedication, and we extend our deepest gratitude to patients and their families for their trust and participation. This year, satri-cel has been granted Breakthrough Therapy Designation and Priority Review by the Center for Drug Evaluation (CDE) of China's National Medical Products Administration (NMPA) for the treatment of Claudin18.2-positive advanced gastric/gastroesophageal junction adenocarcinoma (G/GEJA) in patients who have failed at least two prior lines of therapy. We plan to submit a New Drug Application (NDA) for satri-cel to the NMPA this month and anticipate its approval as the world's first commercially available CAR-T product for solid tumors, bringing benefits to patients.'

CARsgen's Satri-cel Abstract Available on ASCO Website
SHANGHAI, May 22, 2025 /PRNewswire/ -- CARsgen Therapeutics Holdings Limited (Stock Code: a company focused on developing innovative CAR T-cell therapies, announces that an abstract of the research results of the confirmatory Phase II clinical trial of satricabtagene autoleucel ("satri-cel", CT041) (an autologous CAR T-cell product candidate against protein Claudin18.2) for advanced gastric/gastroesophageal junction cancer (G/GEJC) in China (CT041-ST-01, NCT04581473) is available on the American Society of Clinical Oncology ("ASCO") website. Title Claudin18.2-specific CAR T cells (Satri-cel) versus treatment of physician's choice (TPC) for previously treated advanced gastric or gastroesophageal junction cancer (G/GEJC): Primary results from a randomized, open-label, phase II trial (CT041-ST-01) Abstract Number 4003 Session Type and Title Oral Abstract Session – Gastrointestinal Cancer— Gastroesophageal, Pancreatic, and Hepatobiliary Session Date and Time May 31, 2025, 3:00–6:00 PM CDT This open-label, multicenter, randomized controlled trial (RCT) was conducted in China to compare the efficacy and safety of satri-cel versus standard of care (SOC) in CLDN18.2 positive, advanced G/GEJC patients with failure to at least 2 prior lines of treatment. The primary endpoint was PFS assessed by the Independent Review Committee (IRC). Key secondary endpoint was OS. Data cutoff date was Oct 18, 2024. Patients were randomized (2:1) to satri-cel arm or TPC arm. For satri-cel arm, satri-cel dose of 250×106 cells were infused up to 3 times. For TPC arm, one of the standard of care (SOC) drugs (apatinib, paclitaxel, docetaxel, irinotecan or nivolumab) was given per physician's decision. Those who experienced disease progression or drug intolerance in TPC arm could receive subsequent satri-cel, if eligible. From Mar 29, 2022 to Aug 16, 2024, a total of 156 patients were randomized to satri-cel arm (n = 104) or TPC arm (n = 52). Twenty patients in TPC arm received subsequent satri-cel. Median number of prior systemic therapies was 2 in both arms, and 26.9% vs 19.2% had received ≥3 lines. 71.2% vs 65.4% were Lauren diffuse/mixed type. 69.2% vs 59.6% had peritoneal metastasis. In ITT population (i.e., all randomized patients), satri-cel arm showed significant improvement in mPFS by IRC (3.25m vs 1.77m; HR 0.366, 95% CI:0.241, 0.557; p < 0.0001) meeting the primary endpoint with a 63% reduction in risk of disease progression or death. Even with 15.4% (n=16) patients in satri-cel arm failing to receive infusion and nearly 40% (n=20) patients in TPC arm receiving subsequent satri-cel, satri-cel arm still demonstrated a clear trend toward OS benefit (mOS 7.92m vs 5.49m; HR 0.693, 95% CI: 0.457, 1.051; one-sided p = 0.0416) , showing over 30% reduction in mortality risk. More importantly, in mITT population (i.e. patients who were actually treated), 136 patients received study drug (satri-cel 88 patients vs TPC 48 patients), mPFS by IRC was 4.37m vs 1.84m, HR 0.304 (95% CI: 0.195, 0.474), representing a 70% reduction in risk of disease progression or death. The mOS was 8.61m vs 5.49m, HR 0.601 (95%CI: 0.385, 0.939), corresponding to 40% reduction in mortality risk. These results demonstrate that satri-cel treatment benefits were pronounced in patients who actually received CAR-T infusion. Of particular note, 20 TPC patients with subsequent satri-cel infusion achieved an mOS of 9.20 months. When analyzing all 108 patients who received satri-cel infusion (88 patients in satri-cel arm and 20 patients in TPC arm), the mOS reached 9.17 months, while the mOS of 28 patients in TPC arm who did not receive satri-cel treatment was only 3.98 months (HR 0.288; 95% CI: 0.169-0.492). These findings provide further evidence that satri-cel infusion can deliver substantial survival benefits for patients. Furthermore, satri-cel demonstrated a favorable overall safety profile. Only 4 cases of Grade 3 cytokine release syndrome (CRS) were reported, and no Grade 4-5 CRS events were observed. No immune effector cell-associated neurotoxicity syndrome (ICANS) was reported. This is the first confirmatory RCT of CAR-T therapy in solid tumors. Satri-cel demonstrated significant PFS improvement and a clinically meaningful OS benefit with a manageable safety profile in CLDN18.2 positive G/GEJC patients with failure to at least 2 prior lines of treatment, compared to standard therapy. These results support satri-cel as a potential new SOC for advanced G/GEJC. About Satri-cel Satri-cel is an autologous CAR T-cell product candidate against the protein Claudin18.2 that has the potential to be the first-in-class globally. Satri-cel targets the treatment of Claudin18.2 positive solid tumors with a primary focus on G/GEJA and pancreatic cancer (PC). Initiated trials include investigator-initiated trials (CT041-CG4006, NCT03874897), a confirmatory Phase II clinical trial for advanced G/GEJA in China (CT041-ST-01, NCT04581473), a Phase I clinical trial for PC adjuvant therapy in China (CT041-ST-05, NCT05911217), an investigator-initiated trial for satri-cel be used as consolidation treatment following adjuvant therapy in patients with resected G/GEJA (CT041-CG4010, NCT06857786), and a Phase 1b/2 clinical trial for advanced gastric or pancreatic adenocarcinoma in North America (CT041-ST-02, NCT04404595). Satri-cel has been granted Breakthrough Therapy Designation by the Center for Drug Evaluation of China's National Medical Products Administration for the treatment of Claudin18.2-positive advanced G/GEJA in patients who have failed at least two prior lines of therapy in March 2025. Satri-cel was granted Regenerative Medicine Advanced Therapy designation by U.S. FDA for the treatment of advanced G/GEJA with Claudin18.2-positive tumors in January 2022. Satri-cel received Orphan Drug designation from the U.S. FDA in September 2020 for the treatment of G/GEJA.
