Patients should have received, or be intolerant of, standard first-line therapy (e.g., gemcitabine/nab-paclitaxel, FOLFIRINOX) for advanced disease. A short course of current first-line therapy is allowed for the purpose of bridging to manufacturing, but evidence of disease progression on or after at least one line is required prior to infusion (for the dose-expansion phase, patients must have progressed on ≥1 prior systemic regimen).

About this study
Official title: Dual-Target Chimeric Antigen Receptor (CAR) T-Cell Therapy Directed Against Mesothelin and Claudin 18.2 in Patients With Advanced or Metastatic Pancreatic Cancer
Autologous T-cells engineered to express CARs targeting Mesothelin and Claudin18.2, for Unresectable locally advanced or metastatic pancreatic adenocarcinoma (Pancreatic Ductal Adenocarcinoma, PDAC), administered as two separate sequential infusions following lymphodepleting chemotherapy
Read the detailed description
Pancreatic cancer is one of the most lethal malignancies, with a poor prognosis in advanced stages. Mesothelin (MSLN) and Claudin 18.2 (CLDN18.2) are tumor-associated antigens overexpressed in pancreatic adenocarcinoma cells. Both are promising immunotherapy targets, as they are prevalent in pancreatic tumors while largely restricted in normal tissues. CAR-T cell therapies directed at these antigens have shown early evidence of safety and anti-tumor activity. For example, mesothelin-specific CAR T cells have achieved stable disease and metabolic tumor regression in initial trials without dose-limiting toxicity. Similarly, CLDN18.2-specific CAR-T cells yielded objective remissions (including complete remission) in refractory pancreatic cancer, albeit with some gastric mucosal toxicity due to low-level target expression in normal stomach. Targeting two antigens may improve tumor control by addressing antigen heterogeneity and reducing immune escape. This trial evaluates a dual-target CAR-T strategy, in which two separate CAR-T products (one for mesothelin, one for claudin18.2) are given sequentially.

What participants receive

Mesothelin and Claudin 18.2 CAR-T cellsBiological
The intervention in this clinical trial involves a novel approach using Mesothelin and Claudin 18.2 Chimeric Antigen Receptor T (CAR T) cells combined with chemotherapy. The goal is to assess safety and efficacy in patients with specific hematologic malignancies.
Treatment Regimen:
Fludarabine Phosphate (Days -4 to -2): IV administration of fludarabine phosphate over 30 minutes on days -4 to -2. It's part of the preparatory regimen to enhance the body's response to CAR T-cell therapy.
Cyclophosphamide (Day -2): IV cyclophosphamide over 60 minutes on day -2.
Mesothelin and Claudin 18.2 Chimeric Antigen Receptor T Cells (Day 0): IV administration of investigational therapy, Mesothelin and Claudin 18.2 CAR T cells, over 10-20 minutes on day 0.
Additional Doses: Eligible patients responding well to the initial Mesothelin and Claudin 18.2 CAR-T cell infusion without unacceptable side effects and sufficient CAR-T cell availability may receive 2 or 3 additional doses.
| Study group | Role | What they receive |
|---|---|---|
| Mesothelin and Claudin 18.2 CAR T cells, chemotherapy | Experimental | Patients will be administered fludarabine phosphate intravenously (IV) over a 30-minute period on days -4 to -2. Additionally, cyclophosphamide will be administered intravenously (IV) over 60 minutes on day -2. Subsequently, patients will receive Mesothelin and Claudin 18.2 CAR T cells intravenously (IV) over a duration of 10-20 minutes on day 0. Patients who exhibit positive responses to the initial dose of Mesothelin and Claudin 18.2 CAR T cells, do not experience unacceptable side effects, and have a sufficient quantity of cells available may be eligible to receive 2 or 3 additional doses of Mesothelin and Claudin 18.2 CAR T cells. Receives: Biological: Mesothelin and Claudin 18.2 CAR-T cells |

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Mesothelin and Claudin 18.2 CAR-T cells in people with Pancreatic Cancer and Pancreatic Carcinoma, run by Essen Biotech at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 15 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Rhoda M Smith, Phd (+12077706670, clinical-trials@essen-biotech.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence and severity of dose-limiting toxicities (DLTs) following chemotherapy preparative regimen and infusion of CD19/BCMA chimeric antigen receptor (CAR) T cells (time frame: 28 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Jul 2025.
