Dual-Target CAR-NK Cells Directed Against MSLN, EGFR, or HER2 in Advanced NSCLC

A Phase 1/2, Open-label, Biomarker-guided Study of Dual-target Chimeric Antigen Receptor Natural Killer (CAR-NK) Cells Targeting Mesothelin (MSLN) With EGFR or HER2/ERBB2, or EGFR With HER2/ERBB2, in Participants With Advanced/Metastatic Non-small Cell Lung Cancer (NSCLC)

Brief summary

This is a two-part, biomarker-guided Phase 1/2 study evaluating the safety, feasibility, and preliminary anti-tumor activity of off-the-shelf dual-target CAR-NK cells in participants with advanced or metastatic NSCLC whose tumors co-express at least two of the following antigens: Mesothelin (MSLN), EGFR, and HER2/ERBB2. Participants will receive lymphodepleting chemotherapy followed by infusion of the CAR-NK product matched to their tumor antigen profile. A data-driven interim assessment will be used to select the most suitable construct for expansion.

Detailed description

The study includes Part A (dose escalation) and Part B (dose expansion). In Part A, participants are assigned to one of three dual-target CAR-NK constructs based on tumor antigen co-expression (IHC and/or RNA profiling): MSLN/EGFR, MSLN/HER2, or EGFR/HER2. Dose escalation within each construct follows a standard 3+3 design to identify a recommended Phase 2 dose (RP2D). In Part B, the study expands at the RP2D and may adaptively prioritize the construct demonstrating the most favorable benefit-risk profile (e.g., acceptable safety with early signals of response). Key exploratory objectives include CAR-NK persistence, immune pharmacodynamics, cytokine profiling, and correlations between antigen density and clinical outcomes.

Interventions

Allogeneic cord-blood-derived NK cells engineered to express a dual-target CAR (tandem OR-gate) and IL-15 for enhanced persistence; includes an inducible safety switch (e.g., iCasp9). Infused intravenously on Day 0 (with optional repeat infusion on Day 7 in expansion, per protocol).

Fludarabine + Cyclophosphamide administered on Days -5, -4, and -3 prior to CAR-NK infusion

OTHERSupportive Care

Premedication and management per institutional guidelines (e.g., acetaminophen/antihistamine pre-infusion; tocilizumab and corticosteroids per CRS/ICANS management algorithm)

Intervention model description

Participants are assigned to a construct based on tumor antigen co-expression. Each construct undergoes dose escalation (3+3) to determine RP2D, followed by expansion; an interim assessment may select one construct for larger expansion.

Inclusion criteria

* Histologically or cytologically confirmed NSCLC that is unresectable Stage IIIB/IIIC or Stage IV, with radiographic progression on or after standard-of-care therapy (including platinum-based chemotherapy and immune checkpoint inhibitor when appropriate). * At least one measurable lesion per RECIST v1.1. * Archival tumor tissue available (or willingness to undergo a fresh biopsy) for antigen testing. * Tumor co-expression of at least two of the following antigens at screening: MSLN, EGFR, HER2/ERBB2. Example thresholds: IHC ≥2+ in ≥50% of tumor cells for each required antigen (or an equivalent RNA expression threshold). * ECOG performance status 0-1. * Adequate organ function (hematologic, hepatic, renal) as defined by protocol laboratory limits. * Life expectancy ≥12 weeks. * Negative pregnancy test for individuals of childbearing potential; agreement to use effective contraception for the study-defined period. * Ability to understand and willingness to sign written informed consent.

Exclusion criteria

* Active, uncontrolled central nervous system (CNS) metastases. Participants with previously treated/stable CNS disease may be eligible if clinically stable and off high-dose corticosteroids. * Prior gene-modified cellular therapy (e.g., CAR-T, CAR-NK, TCR-T) within 3 months, or any prior therapy that in the investigator's judgment increases risk of severe toxicity. * History of severe cytokine release syndrome (CRS) or immune effector cell-associated neurotoxicity syndrome (ICANS) with prior therapies. * Clinically significant interstitial lung disease or pneumonitis requiring systemic steroids, or uncontrolled pulmonary comorbidity that would confound toxicity monitoring.
