This study will investigate the safety and tolerability of ADP-A2M4CD8 T-cell therapy in subjects who have the appropriate human leukocyte antigen (HLA) and MAGE-A4 tumor antigen. Tumor indications include endometrial, esophageal, esophagogastric junction (EGJ), gastric, head and neck, melanoma, non-small cell lung (NSCLC), ovarian or urothelial cancer.



Endometrial Esophageal Cancer Esophagogastric Junction (EGJ) Gastric (stomach) Head and Neck Melanoma Non-small Cell Lung (NSCLC) Ovarian Cancer

Condition Endometrial Cancer, Esophageal Cancer, Esophagogastric Junction (EGJ), Gastric (Stomach) Cancer, Head and Neck Cancer, Melanoma, Ovarian Cancer, Non-small Cell Lung (NSCLC), Urothelial Cancer
Treatment Autologous genetically modified ADP-A2M4CD8 cells, Autologous genetically modified ADP-A2M4CD8 cells alone or in combination with nivolumab every four weeks
Clinical Study IdentifierNCT04044859
