Clinical trials

This study is a single-center, single-arm, open-label, investigator-initiated early exploratory clinical trial designed to evaluate the safety and efficacy of STR-P005 in subjects with relapsed/refractory autoimmune diseases. The study will employ the traditional "3+3" dose escalation model, setting up 3 dose groups: Amg/kg, Bmg/kg, C mg/kg. Dose Group 1 will serve as the starting dose, with two cohorts A and B within this group aimed at optimizing the dosing frequency of STR-P005. Cohort A will receive dosing every 3 days (Q3D), on D1, D4, D7 (3 doses) constituting one cycle, which can be repeated for 2 cycles. Cohort B will receive dosing every 4 days (Q4D), on D1, D4 (2 doses) constituting one cycle, which can be repeated for 2 cycles. Based on the preliminary safety data, efficacy information, and PK/PD parameters obtained from Cohorts 1A and 1B, the investigators will select the superior regimen and escalate sequentially to Dose Groups 2 and 3. If no MTD is found after dose escalation through the 3 groups, based on all available preliminary safety data, efficacy information, and PK/PD parameters, higher doses may be added for further exploration of safety and efficacy after discussion by the SRC.

This is a single-center, non-randomized, open-label, single-arm exploratory clinical study, using Bayesian Optimal Interval (BOIN) design. Three dose groups are planned: DL1 XX mg/kg, DL2 XXmg/kg, DL3 XXmg/kg. Starting dose is XX mg/kg. Each treatment cycle is 28 days, with 4 infusions on D1, D4, D7, D10; 1-2 cycles. The investigator may escalate to higher doses to further explore safety and efficacy of STR-P004 based on preliminary safety data, efficacy information, and PK/PD parameters obtained.

This is a single-arm, single-center, open-label, multiple-dose, dose-escalation early clinical study aimed at evaluating the safety, tolerability, pharmacokinetic characteristics, and preliminary antitumor activity of STR-P004 in subjects with relapsed/refractory CD19-positive acute lymphoblastic leukemia.

This study is a single-arm, single-center, open-label, multiple-dose, dose-escalation early clinical study aimed at evaluating the safety, tolerability, and pharmacokinetic profile of STR-P004 in subjects with relapsed/refractory CD19-positive B-cell non-Hodgkin lymphoma, and preliminarily observing its antitumor activity.
