NY-ESO-1-redirected T Cells in Patients With Advanced Melanoma and Sarcoma
Sponsor: Centre Hospitalier Universitaire Vaudois
Summary
A single center, dose escalaion, Phase I clinical trial to demonstrate safety and efficacy of LauT-1, autologous "New York Esophageal Squamous Cell Carcinoma-1 T-Cell Receptor (NY-ESO-1 TCR)-directed T cells in combination with non-myeloablative (NMA) lymphodepleting chemotherapy and low dose irradiation (LDI) in patients with NY-ESO-1 positive sarcoma and melanoma.
Official title: A Phase I Study Evaluating Safety and Feasibility of Redirected Autologous T Cells Expressing a High Affinity TCR Specific for NY-ESO-1 (LauT-1) in Patients With Advanced Melanoma and Sarcoma

Interventions
NY-ESO-1 TCR redirected autologous T cell product
Ex vivo expanded autologous CD4+/CD8+ cells expressing the transgenic TCR I53F recognizing NY-ESO-1 peptides presented on tumor cells in the context of HLA-A\*02. Cohort 1: The LauT-1-ACT infusion contains a minimum of 3x10\^8 transduced cells (i.e. CD3+vβ13.1+) and a maximum of 1x10\^10 total cells. Cohort 2 : Patients will receive a fixed dose of 3x10\^8 transduced LauT-1 cells (i.e. CD3+vβ13.1+) split over 2 administrations. Cohort 3: Patients will receive a fixed dose of 6x10\^8 transduced LauT-1 cells (i.e. CD3+vβ13.1+) split over 2 administrations.
Low-dose irradiation
1Gy will be administered using tomotherapy (Accuray) to all irradiable lesions, to all cohorts before the (first) LauT-1 infusion.
Non-myeloablative lymphodepleting chemotherapy
Cohort 1: Fludarabine (30 mg/m2 per day, from D-6 to D-3) and cyclophosphamide (2400 mg/ m2 x 2 days, on days -6 and -5) are administered as an IV infusion. The cyclophosphamide dose may be reduced to 1800mg/m2 on days -6 and -5, if the patient has previously been exposed to significant cumulative doses of chemotherapy). Cohorts 2 and 3: Fludarabine (30 mg/m2 per day, from D-6 to D-3) and cyclophosphamide (900 mg/ m2 x 2 days, on days -6 and -5) are administered as an IV infusion.
