Detailed Description
In the dose-escalation phase of the Phase I clinical trial, a traditional 3+3 trial design was adopted, with a total of 3 dose groups designed. The dose of T/kg was gradually increased, and a total of 12-18 subjects with relapsed/refractory neuroblastoma were enrolled.Within each dose group, the next subject can be dosed after the previous subject has completed at least 14 days of safety observations. After the last subject of each dose group completed the dose-limited toxicity (DLT) evaluation within 28 days after a single dose, the SMC (Safety Monitoring Committee) agreed to enter the next dose group after evaluating the clinical safety data. After that, the enrolment treatment for the next dose group can be started.When 1 DLT occurs in 3 subjects in a dose group, 3 additional subjects in the same dose group (up to 6 subjects in this dose group complete the DLT assessment): If the additional 3 subjects If no DLT occurs, continue dose escalation; if 1 out of 3 additional subjects develops DLT, stop dose escalation; if > 1 of 3 additional subjects develops DLT DLT, then stop the dose escalation, and at the same time need to reduce a dose to continue to enroll 3 subjects for DLT evaluation.
In the dose expansion phase of the Phase I clinical trial, SMC will review the obtained safety and available data on efficacy, PK, immunogenicity, etc., and give the RP2D dose after comprehensive evaluation. In the dose expansion phase, the RP2D dose group will continue to be enrolled 3 ~6 subjects, further clarify the preliminary efficacy and safety of RP2D.
