Summary

This is a single arm, open-label, multi-center, pilot studies (Investigator Initiated Trial, IIT) to evaluate the safety, preliminary efficacy, pharmacokinetics of universal T-cells engineered with chimeric natural killer receptor (CNK-UT) to treat the patients with relapsed/refractory Neuroblastoma.

Detailed description

This is a single arm, open-label, phase I, dose escalation/dose expansion study to assess the safety of CNK-UT cells therapy, and to obtain the preliminary efficacy and pharmacokinetics result in participants who have been diagnosed with relapsed/refractory Neuroblastoma.

Conditions

• Neuroblastoma, Recurrent, Refractory

Interventions

Type	Name	Description
DRUG	Chimeric Natural Killer Receptor Universal T-cells (CNK-UT)	OUTLINE: This is a dose-escalation study of CNK-UT cells followed by a dose-expansion study. 1. Dose Escalation (Single Ascending Dose Study, SAD): During SAD study stage, the participants will be intravenous infused with CNK-UT cells (3\~34×10\^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. 2. Dose Expansion (multiple ascending dose study, MAD): During MAD study stage, the participants will receive multiple doses of CNK-UT cells. The dosage and frequency of drug administration in the dose expansion stage can be adjusted and determined according to the SAD study.
