Brief Summary

Single-arm, dose-increasing setting study of CAR macrophages in Mesothelin overexpressing solid tumors.

Detailed Description

This study was a single-arm, single-center, dose-increasing design, using the "3+3" approach for dose escalation, to evaluate the safety, tolerability and initial effectiveness of SY001, and to evaluate the pharmacokinetic characteristics, cytokines and the correlation between the efficacy of SY001.

SY001 Targets Mesothelin positive solid tumors in a Dose-increasing SettingSY001Patients with mesothelin-positive ovarian cancer were treated with an SY001 injection in combination with an anti-PD-1 antibody. Patient 001 received 1109 SY001 CAR-pMACs via intravenous injection. Following a two-month period in which the treatment's safety was confirmed, this patient underwent another two does of 1109 SY001 cells on both day 1 and day 3. Prior to the CAR-pMACs infusion on day 1, a PD1 antibody Tislelizumab Injection was administered. In the case of the patient 002, SY001 treatment was delivered intravenously on three occasions: day 1, day 3, and day 5. The same as the first patient's protocol, Tislelizumab was given prior to the CAR-pMACs on day 1.
Primary Outcome Measures
NameTimeMethod
Identification of Maximum Tolerated Dose (MTD)up to 28 days after SY001 infusion.

MTD will be determined based on DLTs observed during the first 28 days of study treatment.

Secondary Outcome Measures
NameTimeMethod
Objective response rate (ORR)3 months

Treatment response was assessed according to the criteria of RECIST 1.1, with PET-CT scans being the primary method used to evaluate tumor progression.

Maximum Plasma Concentration of cytokines (Cmax)1 month

Changes in cytokines in peripheral blood after infusion of SY001.

Time to Peak (Tmax)1 month

Changes in the CAR gene copy number after infusion of SY001; time to peak (Tmax) from 0 to 1 month.

Area Under the Plasma Concentration Versus Time Curve (AUC)1 month

Changes in the CAR gene copy number after infusion of SY001, area under the concentration-time curve (AUC) from 0 to 1 month
