Descriptive Information

• Brief Title: MAGE-A4ᶜ¹º³²T for Multi-Tumor
• Official Title: Phase 1 Dose Escalation, Multi-tumor Study to Assess the Safety, Tolerability and Antitumor Activity of Genetically Engineered MAGE-A4ᶜ¹º³²T in HLA-A2+ Subjects With MAGE-A4 Positive Tumors
• Brief Summary: This study will investigate the safety and tolerability of MAGE-A4ᶜ¹º³²T cell therapy in subjects who have the appropriate HLA-A2 tissue marker and whose urinary bladder, melanoma, head and neck, ovarian, non-small cell lung, esophageal, gastric, synovial sarcoma, or myxoid/round call liposarcoma (MRCLS) tumor has the MAGE-A4 protein expressed. This study will take a subject's T cells and give them a T cell receptor protein that recognizes and attacks the tumors. This study has a substudy component that will investigate the safety and tolerability of MAGE-A4c1032T cell therapy in combination with low dose radiation in up to 10 subjects.
