Safety and Efficacy of MAGE-A3/A6 T Cell Receptor Engineered T Cells (KITE-718) in HLA-DPB1*04:01 Positive Adults With Advanced Cancers

Solid Tumor Clinical Trial

Official title: A Phase 1 Study Evaluating the Safety and Efficacy of MAGE-A3/A6 T Cell Receptor Engineered T Cells (KITE-718) in HLA-DPB1*04:01 Positive Subjects With Advanced Cancers

Status Terminated

Clinical Trial Summary

The primary objectives of Phase 1A are to evaluate the safety of KITE-718, determine a recommended Phase 1B dose, and to evaluate the efficacy of KITE-718 in Phase 1B.

Clinical Trial Description

Participants found to be human leukocyte antigen (HLA)-DPB1*04:01 positive and whose tumors are MAGE-A3 and/or MAGE-A6 positive can participate if all eligibility criteria are met. Other tests required to determine eligibility include a physical exam, electrocardiogram (ECG) and echocardiogram (ECHO) of the heart, CT or MRI scans, and blood draws. Eligible participants have white blood cells collected by leukapheresis. These cells are genetically modified to make the experimental treatment KITE-718. The desired outcome is that the genetically modified T cells will target tumor cells that express MAGE-A3 and/or MAGE-A6, which are proteins that can be expressed by cancer cells. Participants receive chemotherapy prior to the KITE-718 infusion. After the KITE-718 infusion, participants will be followed for side effects and have scans performed to see any potential impact on their cancers. Study procedures may be performed while hospitalized and/or in the outpatient setting. Subjects who received an infusion of KITE-718 will complete the remainder of the 15 year follow-up assessments in a separate long-term follow-up study, KT-US-982-5968 ;
