TCR-engineered T Cells (NW-101C) in Patients With Solid Malignant Tumors

A Phase I, Multicenter, Dose-escalation, Single-arm Study of PRAME Antigen-targeted TCR-T Cells(NW-101C) in the Treatment of Subjects With Advanced Solid Malignant Tumors.

This clinical trial is a prospective, dose-escalation, multicenter, single- arm, Phase 1 clinical trial to evaluate the safety, tolerability, PK and preliminary clinical activity of PRAME Antigen-targeted TCR-T Cells (NW-101C) infusion in patients with previously heavily treated, metastatic solid malignant tumors.

Using a classic 3+3 dose escalation design, this study will enroll ~24 subjects to characterize the safety and preliminary anti-tumor activity of NW-101C.

SCREENING: Patient eligibility will be determined by protocol inclusion/exclusion criteria including HLA (human leukocyte antigen) and a biopsy (or collection of archival tumor tissue) for biomarker screening. Leukapheresis for potential manufacturing of the NW-101C cellular product may be performed,if patients are HLA-A*02:01 positive and meet the eligibility criteria for leukapheresis.

MANUFACTURING: NW-101C products will be made from the patients' white blood cells.

TREATMENT: Lymphodepletion with cyclophosphamide and fludarabine will occur in the days before the NW-101C product infusion to improve the duration of time that NW-101C product stays in the body. The patient will be admitted to the hospital during the T-cell infusion until 28 days following NW-101C infusion. After the NW-101C product infusion, dose -limiting toxicities (DLT) will be assessed from the infusion of NW-101C until 28 days following the infusion of NW-101C.
