Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
CNK-UT cell Therapy
1. Dose Escalation：Single-dose intravenous injection of CNK-UT cells (3×10\^7 CNK+ cells/kg).
2. Dose Expansion：Multiple-dose intravenous injection of CNK-UT cells (6-10×10\^7 CNK+ cells/kg)according to the results of dose escalation.
Chimeric Natural Killer Receptor Universal T-cells (CNK-UT)
Dose Escalation (Single Ascending Dose Study, SAD): During SAD study stage, the participants will be intravenous infused with CNK-UT cells (3×10\^7 CNK+ cells/kg)with a"3 +3" design to determine the maximum tolerated dose. During single ascending dose (SAD) study stage, the participants will receive a single dose of CNK-UT cells before the DLT observation period (21 days). If the participants do not experience DLT, they will be able to enter a multiple ascending dose (MAD) study stage.
Dose Expansion (multiple ascending dose study, MAD): During MAD study stage, the participants will receive multiple doses of CNK-UT cells(6-10×10\^7 CNK+ cells/kg). The dosage and frequency of drug administration in the dose expansion stage can be adjusted and determined according to the SAD study.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Participants diagnosed with grade II\~IV steroid-refractory/resistant or steroid-dependent aGVHD after allogeneic hematopoietic stem cell transplantation.
3. ECOG physical status score 0\~3;
4. Estimated life expectancy \> 12 weeks;
5. Female participants of childbearing age must undergo a serum or urine pregnancy test before enrollment, and the results must be negative, and agree to take acceptable measures to minimize the possibility of pregnancy during the trial; For female participants of childbearing age or male participants whose sexual partners are women of childbearing age, effective contraceptive measures should be taken during the study and for at least 6 months following the last dose of the study cells infusion.
6. Participants voluntarily participate in clinical trial; Understand and know this study, sign an informed consent form, and be willing to follow all experimental procedures.
Exclusion Criteria
2. Participants with a history of organ transplantation;
3. Participants who have previously undergone more than one allogeneic hematopoietic stem cell transplantation.
4. Uncontrolled hypertension as determined by principal investigator, a history of hypertensive crisis or hypertensive encephalopathy; symptomatic congestive heart failure (New York Heart Association classification III-IV); symptomatic or poorly controlled arrhythmias; a history of congenital long QT syndrome or a corrected QT interval (QTc) \> 500 ms at screening (calculated using the Fridericia method)..
5. Systemic diseases deemed unstable by principal investigator include, but are not limited to, severe pulmonary, hepatic, renal, or metabolic disorders that require pharmacological intervention (excluding complications related to allogeneic hematopoietic stem cell transplantation).
6. Active pulmonary tuberculosis (TB), who is receiving anti-tuberculosis treatment or has received anti-tuberculosis treatment within 1 year before enrollment; human immunodeficiency virus (HIV) infection, known syphilis infection.
7. Severe infections that are active or poorly controlled clinically.
8. Participants who have received treatment from other clinical trials within 12 weeks prior to the initiation of the study.
9. Participants who have previously used any gene therapy products prior to the initiation of the study.
10. Allergic to components of CNK-UT injection.
11. Participants suffer from known mental or substance abuse disorders, which may interfere with their ability to comply with research requirements.
12. Women who are pregnant or breastfeeding, as well as male or female participants who have planned for birth within 1 year after receiving medication.
13. Uncontrolled/uncorrectable metabolic disorders or other non-malignant organ diseases or systemic diseases or secondary reactions to cancer, which can lead to higher medical risk and/or uncertainty in survival assessments.
14. Other situations that the participant is identified by the investigator as unsuitable to participate in the study.
