Phase

PHASE1

Detailed Description:

Primary Objective: 1. To determine the safety, tolerability, maximum tolerated dose (MTD), and recommended Phase 2 dose (RP2D) of TROP2-CAR-NK cells combined with cetuximab in patients with MRD CRC. 2. To evaluate circulating tumor DNA (ctDNA) clearance (undetectable) at 3 months Secondary Objectives: 1. Determine progression-free survival. 2. To quantify the persistence of infused allogeneic donor TROP2-CAR-NK cells in the peripheral blood of the recipient. 3. To evaluate blood- and tissue-based biomarkers at baseline associated with response and resistance to TROP2-CAR-NK cell infusion in combination with cetuximab. Exploratory Objectives: 1. To profile and assess dynamic immune changes in the tumor microenvironment. 2. Quantify the average circulating ctDNA change from TROP2-CAR-NK infusion to progression or initiation of a new cancer therapy and association with PFS. 3. To evaluate patient-reported quality of life (QoL).

  • 4. In both the dose escalation and dose expansion cohorts, participants must have documented colorectal cancer (CRC) with MRD following complete disease resection followed by standard-of-care adjuvant treatment.

    • * Not a woman of childbearing potential (WOCBP) as defined in Appendix 4 OR
    • * A WOCBP who agrees to follow the contraceptive guidelines in Appendix 4 during the study treatment period and for 6 months post TROP2-CAR-NK cell infusion.
    • 8. Female participants who become pregnant or suspect pregnancy must immediately notify their doctor. Females' participants who become pregnant will be taken off study.
    • 9. Male participants must agree to follow the contraceptive guidelines in Appendix 4 during the study treatment period and for 6 months post TROP2-CAR-NK cell infusion. Male participants who father a child or suspect that they have fathered a child must immediately notify their doctor.
    • 10. WOCBP must have a negative urine pregnancy test within 72 hours prior to the start of lymphodepleting chemotherapy. If a WOCBP has a urine pregnancy test that cannot be confirmed as negative, a serum (beta-human chorionic gonadotropin \[â-hCG\]) pregnancy test will be required.
    • 11. Participants must have adequate organ function as defined below (Table 1) within 10 days prior to the start of lymphodepleting chemotherapy

Adequate Organ Function Laboratory Values Systemic Function Test Laboratory Value Hematologic ANC = ≥1500/ƒÊL Platelets = ≥100,000/ƒÊL Hemoglobin = ≥9.0 g/dLa Renal CrCl by Cockcroft-Gault formula = ≥45 mL/min for patients with creatinine \>1.5 x ULNb Hepatic Total bilirubin = ≤1.5 x ULN OR direct bilirubin ≤ULN for patients with total bilirubin levels \>1.5 x ULN AST and ALT = ≤2.5 x ULN (≤5 x ULN for patients with history of resected liver metastases) Coagulation PT/INR aPT = ≤1.5 x ULN unless patient is receiving anticoagulant therapy as long as PT or aPTT is within therapeutic range
      • 12. Left ventricular ejection fraction \>50%. Of note, those patients with risk factors and/or with LVEF \<55% additional testing may need to be performed as per institutional guidelines and/or PI guidance.
      • 13. Adequate respiratory reserve defined as dyspnea Grade 0 or 1 and saturated oxygen \>92% in room air.
