What to Expect as a Participant
You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.
Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.
This trial targets 60 participants in total. It began in 2026-02-02 with a primary completion date of 2027-02-14.

Brief Summary
This study tests the safety and preliminary anti-tumor activity of an investigational dual-target chimeric antigen receptor natural killer (CAR-NK) cell therapy in adults with advanced breast cancer. After a tumor antigen assessment (HER2/ERBB2, MUC1, ROR1, and in some TNBC cases mesothelin), each participant will receive the most suitable dual-target CAR-NK product for their tumor profile, following short-course lymphodepleting chemotherapy.
Eligibility Criteria
Inclusion Criteria: * Histologically confirmed breast carcinoma that is locally advanced, unresectable, or metastatic. * Disease subtype: HER2-positive breast cancer or triple-negative breast cancer (TNBC). * Progression after, intolerance to, or ineligibility for standard therapies appropriate for the disease subtype and line of therapy. * At least one measurable lesion per RECIST v1.1. * Tumor antigen assessment available (fresh or archival): expression of at least one candidate target antigen (HER2/ERBB2, MUC1, or ROR1). For TNBC, mesothelin assessment may be performed for exploratory analyses. * ECOG performance status 0-1. * Adequate organ function (example thresholds): ANC ≥ 1.0 x 10\^9/L; platelets ≥ 75 x 10\^9/L; hemoglobin * 8 g/dL; AST/ALT ≤ 3x ULN (≤ 5x with liver metastases); total bilirubin ≤ 1.5x ULN; creatinine clearance * 50 mL/min. * Left ventricular ejection fraction (LVEF) ≥ 45% and no uncontrolled cardiac arrhythmia. * Negative pregnancy test for participants of childbearing potential; agreement to use effective contraception during study treatment and for 6 months after last CAR-NK infusion. * Ability to understand and willingness to sign informed consent. Exclusion Criteria: * Active, untreated central nervous system (CNS) metastases or leptomeningeal disease. Patients with treated CNS metastases may be eligible if clinically stable for ≥ 4 weeks and off high-dose steroids. * Prior gene-modified cellular therapy (e.g., CAR-T or CAR-NK) within 6 months or unresolved grade ≥ 2 toxicity from prior cellular therapy. * Clinically significant active autoimmune disease requiring systemic immunosuppression (physiologic steroid replacement permitted). * Uncontrolled infection, including uncontrolled HBV, HCV, or HIV infection (controlled infections may be eligible per investigator). * History of severe hypersensitivity to fludarabine or cyclophosphamide. * Pregnant or breastfeeding. * Concurrent participation in another interventional study that could confound safety or efficacy assessments. * Any condition that, in the investigator's judgment, would make the participant unsuitable for the study (e.g., uncontrolled comorbidity, inability to comply with protocol procedures).
