PRAME-targeted T-cell (NW-101C) therapy for metastatic solid 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.

Phase 1 Interventional Neowise Biotechnology · NCT07266298

This trial will test whether a patient's own PRAME-directed T cells (NW-101C) are safe and show early anti-tumor activity in people with HLA-A*02:01 metastatic solid tumors who have had many prior treatments.

What this trial studies

This is a multicenter, single-arm Phase 1 dose-escalation trial using a classic 3+3 design to define safety and preliminary activity of NW-101C, an autologous PRAME-targeted TCR-T product. Patients undergo HLA and tumor PRAME testing, leukapheresis to collect white blood cells for manufacturing, and lymphodepleting chemotherapy with cyclophosphamide and fludarabine before infusion. Participants are admitted for the T-cell infusion and monitored in hospital through 28 days post-infusion for dose-limiting toxicities, with pharmacokinetic and safety endpoints guiding dose escalation. About 24 subjects will be enrolled to characterize tolerability, PK, and early signs of anti-tumor effect.

Who should consider this trial

Good fit: Adults 18–75 with unresectable or metastatic solid tumors that express PRAME, who are HLA-A*02:01 positive, have ECOG 0–1, adequate organ function, measurable disease, and no standard treatment options are ideal candidates.

Not a fit: Patients who lack HLA-A*02:01, whose tumors are PRAME-negative, who have poor organ function or ECOG >1, or who cannot undergo leukapheresis or lymphodepletion are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, this therapy could shrink tumors or slow disease progression in some patients whose cancers no longer respond to standard treatments.

How similar studies have performed: Engineered TCR-T approaches against shared tumor antigens have produced occasional responses in early trials, but PRAME-directed TCR-T remains relatively novel with limited published clinical data.
