Dual-Target CAR-NK Cells Targeting Mesothelin (MSLN) and MUC1 in Advanced Pancreatic Ductal Adenocarcinoma (DUAL-NK-PDAC)
A Phase 1/2, Open-label, Biomarker-guided, Dose-escalation and Expansion Study of Dual-targeting CAR-NK Cells Directed Against Mesothelin (MSLN) and MUC1, With an Exploratory CLDN18.2/MUC1 Dual-target Cohort, in Patients With Unresectable or Metastatic Pancreatic Ductal Adenocarcinoma (PDAC)
연구 개요
상태
상세 설명
- Rationale: PDAC is characterized by aggressive biology, antigen heterogeneity, and an immunosuppressive tumor microenvironment. Dual-targeting CAR designs aim to reduce antigen-escape by enabling recognition of either target antigen on tumor cells.
- Investigational products: Two off-the-shelf (allogeneic) CAR-NK products are evaluated. EB-DNK101 targets MSLN and MUC1. EB-DNK102 targets CLDN18.2 and MUC1. Both products are engineered to enhance persistence and incorporate an inducible safety switch .
- Target assessment and cohort assignment: Tumor tissue (archival or fresh biopsy) is tested centrally by immunohistochemistry (IHC) for MSLN, MUC1, and CLDN18.2. Participants are assigned to Arm A (MSLN/MUC1) or Arm B (CLDN18.2/MUC1) based on predefined positivity thresholds. If more than one cohort is eligible, assignment prioritizes the strongest antigen expression and product availability.
- Conditioning and administration: Participants receive lymphodepleting chemotherapy followed by intravenous infusion of the assigned CAR-NK product.
Repeat infusions (up to 3 total) may be permitted in the absence of prohibitive toxicity and with at least stable disease. Safety monitoring: Participants are monitored closely for cytokine release syndrome (CRS), immune effector cell-associated neurotoxicity syndrome (ICANS), infusion reactions, and other adverse events.
Dose-limiting toxicities (DLTs) are assessed during the first 28 days after first infusion.
- Efficacy and biomarker assessments: Tumor response is assessed by imaging (RECIST v1.1) at regular intervals (every 8 weeks). Exploratory endpoints include CAR-NK expansion/persistence, cytokine profiling, and association of antigen density with response.
- Target down-selection plan: After completion of Part 1 and an initial subset of Part 2 expansion participants, an internal scientific review compares antigen prevalence, manufacturability, safety, and preliminary activity across cohorts to prioritize the lead dual-target construct for subsequent confirmatory development.

- Life expectancy >= 12 weeks.
- Negative pregnancy test for individuals of childbearing potential; agreement to use effective contraception during study participation and for a protocol-defined follow-up period.
- Ability to understand and willingness to sign written informed consent.
Exclusion Criteria:

- Known active hepatitis B or hepatitis C with detectable viral load; known uncontrolled HIV infection.
- Prior allogeneic hematopoietic stem cell transplant or solid organ transplant.
- Prior gene-modified cellular therapy (e.g., CAR-T/CAR-NK) within 6 months or prior therapy targeting the same antigen(s) Ongoing requirement for systemic immunosuppressive therapy (e.g., chronic corticosteroids above physiologic replacement).
- Clinically significant cardiovascular disease (e.g., recent myocardial infarction, uncontrolled arrhythmia, or NYHA class III/IV heart failure) within a protocol-defined period.
