Multi-center Study of TBI-1301 (INN: Mipetresgene Autoleucel; Mip-cel) in Patients With NY-ESO-1 Positive Synovial Sarcoma

Summary

The purpose of this study is to verify the safety and the efficacy of TBI-1301 for NY-ESO-1 expressing synovial sarcoma when administered following cyclophosphamide/fludarabine pre-treatment.

7. Measurable lesions that are evaluable by the RECIST ver1.1
8. ECOG Performance Status of 0, 1 or 2
9. No treatment such as chemotherapy and be expected to recover fully from the previous treatment at the time of the lymphocytes collection for manufacturing
10. Life expectancy ≥ 16 weeks after consent
11. 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 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.
2. Active metastatic tumor cell invasion into CNS
3. Active multiple cancer
4. Positive for HBs antigen or HBV-DNA observed in serum
5. Positive for HCV antibody and HCV-RNA observed in serum

8. History of hypersensitivity reaction to ingredients or excipients of investigational drugs used in this study
9. History of hypersensitivity reaction to antibiotics used in manufacturing for the investigational drug used in this study.
10. History of treatment with cell therapy or gene therapy
11. Alcohol or drug dependence that may interfere with study participation
12. 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.
