Brief Summary:

This study is for men and women who have a type of sarcoma that has returned after being treated, or that cannot be surgically removed. The specific type of sarcoma is Myxoid / Round Cell Liposarcoma, also known as High Grade Myxoid Liposarcoma.

In addition to this disease patients must also have the tissue type HLA-A*02:01, HLA-A*02:05 or HLA-A*02:06, and a sample of tumor tissue must test positive for the NY-ESO-1 protein.

The study treatment is made from some of the patient's own white blood cells called T cells. T cells are collected from the patient by leukapheresis and sent to a laboratory to be genetically modified, with the aim that they will be able to destroy the cancer cells.

Manufacturing the T cells takes about 1 month to complete. The T cells will be given back to the patient by an intravenous infusion. The purpose of this study is to test whether the T cells have an effect on the cancer and to test whether the treatment can be given safely to patients with this disease.


Condition or disease Intervention/treatment Phase
Neoplasms Genetic: Autologous genetically modified T Cells, NY-ESO-1ᶜ²⁵⁹T Phase 2

Detailed Description:

This is an open label pilot study of gene modified autologous T cells for the treatment of advanced myxoid/ round cell liposarcoma or high-grade myxoid liposarcoma.

Subjects with the HLA-A*02:01, HLA-A*02:05 and/or HLA-A*02:06 allele, whose tumor expresses the NY-ESO-1 antigen and who meet study entry criteria will be eligible for enrollment. Following enrollment, subjects will undergo leukapheresis for collection of autologous cells for processing and manufacture into the NY-ESO-1ᶜ²⁵⁹T cell investigational product.

Leukapheresis is performed to obtain cells for the manufacture of autologous NY-ESO-1ᶜ²⁵⁹T cells. When the manufactured NY-ESO-1ᶜ²⁵⁹T cells are available, subjects will undergo lymphodepleting chemotherapy with cyclophosphamide and fludarabine, followed by a single infusion of NY-ESO-1ᶜ²⁵⁹T (transduced cell range: 1 to 8 billion cells) that will be administered on Day 1.
