Study phase: Phase 1

Overall status: Recruiting

Study design:

Allocation: Non-Randomized

Intervention model: Sequential Assignment

Primary purpose: Treatment

Masking: None (Open Label)

Intervention:

Intervention type: Biological
Intervention name: CD371-specific/YSNVz/I-18 CAR T cells
Description: Cohorts will be infused with escalating doses of CD371-specific/YSNVz/IL-18 CAR T cells with lymphodepleting chemotherapy (LDC) to establish the maximum tolerated dose (MTD). There is a third, lower dose level (step-down dose) available for dose de-escalation in the event of severe toxicity at the first planned dose level.
Arm group label: Dose Level 1
Arm group label: Dose Level 2
Arm group label: Step-Down Dose

Summary: The purpose of this study is to find out whether CD371-YSNVZ-IL18 CAR T cells are safe, and to look for the highest dose of CD371-YSNVZ-IL18 CAR T cells that cause few or mild side effects in participants.
