Brief Summary:
A Phase 1b, open label, multi-center, clinical study of Chimeric Antigen Receptor T Cells (CAR-T) targeting claudin18.2 in patients with advanced gastric or pancreatic adenocarcinoma

Condition or disease Intervention/treatment Phase
Gastric Cancer Pancreatic Cancer Biological: CT041 Phase 1

Detailed Description:

This is an open label, multi-center, Phase 1b clinical trial to evaluate the safety and efficacy of autologous claudin18.2 chimeric antigen receptor T-cell therapy in patients with advanced gastric or pancreatic adenocarcinoma.

Part A of the study will be Dose Escalation followed by Part B, an expansion cohort. Following consent, patients must have tumor tissue evaluated by CLDN18.2 IHC assay. Patients meeting all eligibility criteria will undergo a leukapheresis procedure to collect autologous mononuclear cells for manufacture of investigational drug product (CT041). Following manufacture of the drug product, subjects will receive preconditioning prior to CT041 infusion. All subjects will be asked to continue to undergo long-term gene safety follow-up.

Arm Intervention/treatment
Experimental: anti-claudin18.2 chimeric antigen receptor T-cell therapy
Phase 1 will include two parts, a dose escalation part to determine the recommended dose for the expansion part. During expansion patients will be treated with the recommended dose determined in the expansion part.
Biological: CT041
treatment with anti-claudin18.2 chimeric antigen receptor T-cell infusion




Primary Outcome Measures :
  1. Incidence of Treatment Related adverse events (AEs) [ Time Frame: day 1 - month 12 ]

  2. Identification of Maximum Tolerated Dose (MTD) [ Time Frame: day 1 - month 12 ]
    Incidence of dose-limiting toxicities (DLTs)


Secondary Outcome Measures :
  1. Time to Progression [ Time Frame: day 1 - month 12 ]
    Duration of time from CT041 treatment to progression of disease

  2. Duration of Response [ Time Frame: day 1 - month 12 ]
    Duration of time from first response to progression of disease

  3. Disease Control Rate [ Time Frame: day 1 - month 12 ]
    Percentage of patients response at least 90 days

  4. Progression free survival [ Time Frame: day 1 - month 12 ]
    duration time after CT041 treatment that patient lives without worsening of disease

  5. Overall survival [ Time Frame: day 1 - month 12 ]
    duration time after CT041 treatment that patient lives
