About this trial

This Phase 1/2 study evaluates the safety, feasibility, and preliminary anti-tumor activity of allogeneic donor-derived CAR-NK cells in participants with advanced solid tumors. The CAR target antigen is selected for each participant after tumor profiling using a tissue biopsy and/or liquid biopsy. Participants will receive either a single-target or dual-target CAR-NK product based on the antigen profile.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Age 18-75 years.

Histologically or cytologically confirmed advanced/unresectable or metastatic solid tumor that is relapsed/refractory after standard therapy, or no standard therapy available.

Arm A: ≥1 antigen meets "positive" threshold

Arm B: ≥2 antigens meet "positive" threshold

Disqualifiers

Prior treatment with gene-modified cellular therapy (e.g., CAR-T, CAR-NK) within a defined washout period .

Active, uncontrolled infection requiring IV antibiotics; known uncontrolled HIV; active HBV/HCV with detectable viral load (per local policy).

Active CNS metastases requiring escalating steroids or urgent intervention (stable treated CNS disease may be allowed ).

Active autoimmune disease requiring systemic immunosuppression, or chronic systemic steroids above protocol threshold.

Treatments tested in this trial

  • EB-SELECT Single-Target CAR-NK Cells

    Biological/Vaccine

    Donor-derived CAR-NK cells expressing a single CAR selected from the target menu. WITH Fludarabine (IV) + Cyclophosphamide (IV), administered prior to CAR-NK infusion. Similar conditioning drugs are used in CAR-NK solid tumor trials.

  • Dual-Target Antigen-Selected CAR-NK

    Biological/Vaccine

    Participants whose profiling identifies two actionable antigens, or strong evidence of antigen heterogeneity. WITH Fludarabine (IV) + Cyclophosphamide (IV), administered prior to CAR-NK infusion . Similar conditioning drugs are used in CAR-NK solid tumor trials.
