About this trial

The purpose of this clinical trial is to learn if autologous claudin18.2-directed chimeric antigen receptor T-cell (CAR-T) therapy works to treat claudin18.2 positive solid tumors in adults. It will also learn about the safety and efficacy of the autologous claudin18.2 CAR-T cell product.

The main questions it aims to answer are:

1. What CAR-T-related adverse events (AEs) occur within 3 months after the autologous CAR-T cell infusion? 2. What is the Objective Response Rate (ORR), Progression-free survival (PFS), duration of response (DOR), and overall survival (OS)?

Participants will:

1. Undergo leukapheresis for collection of autologous T cells for CAR-T cell manufacturing. 2. May receive lymphodepletion chemotherapy (fludarabine plus cyclophosphamide) for 3 consecutive days if clinically needed. 3. If lymphodepletion chemotherapy is administered, rest for 2 days on Day -2 and Day -1. 4. Receive autologous CAR-T cells infusion on Day 0. 5. Be hospitalized for at least 7 days post-infusion for close safety monitoring and remain within 2 hours of the treatment facility for at least 28 days. 6. Visit the clinic at Day 14, Day 28, then monthly for up to 12 months after CAR-T cells infusion, with continued long-term follow-up for safety and persistence.

Eligibility criteria

Qualifiers

Aged 18 to 75 years at the time of signing the the informed consent form (ICF).

Pathologically confirmed advanced solid tumor and patients have failed at least 2 prior lines of systemic therapy; or patients with advanced pancreatic cancer who have failed at least 1 prior line of systemic therapy.

Tumor tissue testing meets the requirement: Positive for Claudin 18.2 (CLDN18.2) by immunohistochemistry (IHC) staining.

Estimated life expectancy ≥ 12 weeks from the time of screening.

Disqualifiers

Pregnant or lactating women.

Serologically positive for human immunodeficiency virus (HIV), Treponema pallidum, or hepatitis C virus (HCV); or positive for Epstein-Barr virus (EBV)-DNA, cytomegalovirus (CMV)-DNA, or severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid.

Presence of any uncontrolled active infection, including but not limited to active tuberculosis and active hepatitis B virus (HBV) infection (defined as HBsAg positive with detectable HBV-DNA).

Persistent toxicities from prior anti-tumor therapy that have not resolved to Common Terminology Criteria for Adverse Events (CTCAE) grade ≤ 1, except for tolerable events such as alopecia as determined by the investigator.
