Summary

This is a Phase I, single-arm, open-label, dose-escalation and dose-expansion study. The primary objective is to evaluate the safety, tolerability, efficacy, pharmacokinetics, and pharmacodynamics of YTS109 STAR-T cell therapy in patients with autoimmune hemolytic anemia who have failed ≥3 lines of therapy.

This study set up two dosage groups: 1e6 STAR+T cells/kg and 2e6 STAR+T cells/kg. With the starting dose of 1e6 STAR+T cells/kg, it was conducted according to the traditional 3+3 design rule. In this study, if the safety was good but the efficacy was not satisfactory at the dosage level of 2e6 STAR+T cells/kg, SRC could decide whether to continue increasing the dose to 3e6 STAR+T cells/kg based on the clinical preclinical data, cumulative safety, tolerance, preliminary efficacy, PK and other results.

If the subject shows no response (NR) or experiences recurrence after remission, a second infusion may be administered-provided the patient voluntarily consents and the investigator, after comprehensive assessment, determines that the potential benefits outweigh the risks. The investigator may decide on the timing of re-infusion, the use of lymphodepleting pretreatment, and the dose and number of re-infusions based on prior safety, efficacy, and pharmacokinetic (PK) data.
