About this trial
This study is an open-label, multi-center, adaptive Phase 1/2 trial evaluating the safety, feasibility, and preliminary antitumor activity of allogeneic dual-target CAR-NK cell products in adults with relapsed or refractory small cell lung cancer (SCLC). Three candidate dual-target constructs (DLL3/CD56, DLL3/GD2, and CD56/GD2) will be assessed during dose escalation; a pre-specified interim assessment will select the most suitable construct to proceed into an expansion cohort at the recommended Phase 2 dose (RP2D).
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Age 18 to 75 years at the time of consent.
Histologically or cytologically confirmed small cell lung cancer (SCLC) that is metastatic, extensive-stage, or unresectable, and relapsed or refractory after at least 1 prior systemic regimen (must include a platinum-based regimen unless contraindicated).
At least one measurable lesion per RECIST v1.1.
ECOG performance status 0 to 1.
Disqualifiers
Active or uncontrolled CNS metastases or leptomeningeal disease (treated/stable CNS metastases may be allowed per protocol).
Prior treatment with CAR-T, CAR-NK, or other gene-modified cellular therapy within 6 months (or any prior therapy directed against the investigational target antigens if it would confound safety/efficacy assessment).
Allogeneic hematopoietic stem cell transplant within 6 months or active graft-versus-host disease.
Active uncontrolled infection, including uncontrolled HIV, active hepatitis B or C with viremia, or active tuberculosis.
