Study Overview
Brief Summary
The purpose of this study is to evaluate the safety and the efficacy of TBI-1301 for NY-ESO-1 expressing synovial sarcoma when administered following cyclophosphamide pre-treatment.
Detailed Description
Following pre-treatment with cyclophosphamide, NY-ESO-1-specific T cell receptor (TCR) gene transduced T lymphocytes are transferred to human leukocyte antigen (HLA)-A*02:01 or HLA-A*02:06 positive patients with synovial sarcoma expressing NY-ESO-1, which are surgically unresectable and refractory to anthracycline therapy. The primary objective is to evaluate the safety in the phase 1 and the efficacy in the phase 2.

- •ECOG Performance Status of 0, 1 or 2
- •No treatment such as chemotherapy and be expected to recover fully from the previous treatment at the time of the lymphocytes collection for manufacturing
- •Life expectancy ≥ 16 weeks after consent
- •No severe damage on the major organs (bone marrow, heart, lung, liver, kidney, etc) and meet the following lab value criteria; Total bilirubin ≤ 1.5 x upper limit of normal (ULN); AST(GOT), ALT(GPT) < 3.0 x ULN; Creatinine < 1.5 x ULN; 2,500/μL < WBC ≤ULN; Hemoglobin ≥ 8.0g/dL; Platelets ≥ 75,000/μL
- •Patients must be able to understand the study contents and to give a written consent at his/her free will. Additionally, if patients are below 20 years of age, proxies must be able to give a written consent.
Exclusion Criteria
- •Patients with the following conditions are excluded from the study; Unstable angina, cardiac infarction, or heart failure; Uncontrolled diabetes or hypertension; Active infection; Obvious interstitial pneumonia or lung fibrosis by chest X-ray; Active autoimmune disease requiring steroids or immunosuppressive therapy.
- •Active metastatic tumor cell invasion into CNS
- •Active multiple cancer

- •History of serious hypersensitivity reactions to bovine or murine derived substances.
- •History of hypersensitivity reaction to ingredients or excipients of investigational drugs used in this study
- •History of hypersensitivity reaction to antibiotics used in manufacturing for the investigational drug used in this study.
- •Pregnant females, lactating females (except when they cease and do not resume lactation) or female and male patients who cannot agree to practice the adequate birth control from the consent to 6 months after infusion of the investigational drug.
- •Clinically significant systemic illness that in the judgment of the PI or sub-investigator would compromise the patient's ability to tolerate protocol therapy or significantly increase the risk of complications.
