Interventions
Conditioning regimen: Days -9 to -3: Venetoclax administered with a target dose of 200 mg/day. Days -5 to -4: Cytarabine administered at 500 mg/m²/day. Days -5 to -3: Cyclophosphamide at 300 mg/m²/day plus Fludarabine at 30 mg/m²/day. Day 0: Infusion of CT0890B CAR-T cells at one of four dose levels using an i3+3 Dose-Escalation Design: 1.5 × 10⁸ total cells, 3.0 × 10⁸ total cells, 4.5 × 10⁸ total cells, 6.0 × 10⁸ total cells
Eligibility Criteria
You may qualify if:
- Age 18-70 years (inclusive), male or female.

- Participants who have received autologous stem cell transplantation or allogeneic stem cell transplantation within 12 weeks
- Participants who have received prior immunotherapy targeting NKG2DL;
- Participant has clinically significant active GVHD or is receiving systemic corticosteroids for GVHD;
- Participant has any of the following at screening:
- )Active, uncontrolled systemic infection or requiring intravenous anti-infective agents 2)Any of the following cardiac conditions, including:
- New York Heart Association Class III-IV heart failure;
- History of myocardial infarction, coronary artery bypass grafting, or unstable angina within 6 months prior to Qinglin;
