About

Following pre-treatment with cyclophosphamide and/or fludarabine, MAGE-A4-specific TCR gene transduced T lymphocytes are transferred to the patients with MAGE-A4-expressing solid tumors.

Full description

Following pre-treatment with cyclophosphamide alone or in combination with fludarabine, MAGE-A4-specific TCR gene transduced T lymphocytes are transferred to HLA-A*24:02 positive patients with solid tumors which are 1) unresectable, refractory to standard therapy (chemotherapy, radiotherapy, etc), metastatic or recurrent, and 2) MAGE-A4-expressing. The primary objective is to evaluate the safety and in vivo kinetics, and the secondary is to evaluate clinical effect.

8. Percutaneous Oxygen saturation: < 94％

9. History of hypersensitivity reactions to bovine or murine derived substances.

10. History of hypersensitivity reaction to drugs used in this study

11. Psychological disorder or drug dependency which may have impact on the consent.

12. Pregnant females, lactating females (except when they cease and don't resume lactation) or female and male patients who cannot agree to practice the adequate birth control after the consent during the study

13. 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.
