CAR-T Cell

Subjects exposed to gene therapy products (GTPs) may be at risk for delayed or long-term adverse events. This is a long-term follow-up (LTFU) protocol designed to evaluate the long-term safety of Seattle Children's Therapeutics (SCTx) GTPs and incorporates in monitoring guidance from the U.S. Food and Drug Administration (FDA). Subjects will be followed for up to 15 years starting from the date of the most recent infusion of an SCTx GTP. Subjects planning to receive, or who have received, at least one infusion of an SCTx GTP will be offered participation in this LTFU study. Subjects enrolled in this study will have safety assessments and laboratory evaluations performed at scheduled intervals for each unique SCTx GTP received. No treatment is administered in this LTFU study.

This is a single-center, single-arm, open-label phase 1/2 study of CART19 in children and young adults with refractory Systemic lupus erythematosus (SLE), including both patients diagnosed with lupus nephritis (LN) and patients with non-renal Systemic lupus erythematosus (SLE). Phase 1 will evaluate the safety of CART19 in 6-12 patients with Systemic lupus erythematosus (SLE). There is no planned dose escalation, but a dose de-escalation will be made based on the incidence of Dose Limiting Toxicities. Phase 2 will evaluate the efficacy and further evaluate the safety of CART19 in this population.

CAR T cells therapy has transformed the prognostic of relapsed/refractory large B cells lymphomas. Relapse however is still high and multiple causes have been studied. CAR expansion seems to be necessary to for response and lymphodepletion type and exposure, notably to fludarabine, associated with expansion and response. The aim of the study is to analyse prospectivaly Fludarabine and cyclophosphamide exposure and correlate exposure to expansion, therapeutic response and survival.

The third generation of CAR-T cells that target GPC3, Mesothelin, Claudin18.2, GUCY2C, B7-H3, PSCA, PSMA, MUC1, TGFβ, HER2, Lewis-Y, AXL, or EGFR have been constructed respectively and their anti-cancer function has been verified by multiple in vitro and in vivo studies.Clinical studies will be performed to test the anti-cancer function of the these individual or combination of the CAR-T cells for immunotherapy of human cancer patients with GPC3, Mesothelin, Claudin18.2, GUCY2C, B7-H3, PSCA, PSMA, MUC1, TGFβ, HER2, Lewis-Y, AXL, or EGFR expressions. In this phase I study, the safety, tolerance, and preliminary efficacy of the GPC3/Mesothelin/Claudin18.2/GUCY2C/B7-H3/PSCA/PSMA/MUC1/TGFβ/HER2/Lewis-Y/AXL/EGFR -CAR-T cell immunotherapy on human cancers will firstly be tested.
