Solid Tumor Analysis for HLA Loss of Heterozygosity (LOH) and Apheresis for CAR T- Cell Manufacturing (NCT04981119)

An Observational Study Obtaining Solid Tumor Tissue From Participants and Apheresis for CAR T-Cell Therapy Manufacturing

๐ŸŸข Recruiting Interventional Protocol ๐Ÿ“Š Observational Clinical Research Sponsor: A2 Biotherapeutics Inc.

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

Objective: To collect information on how often a solid tumor cancer might lose the Human Leukocyte Antigen (HLA) by next generation sequencing and perform apheresis to collect and store an eligible participant's own T cells for future use to make CAR T-Cell therapy for their disease treatment. Design: This is a non-interventional, observational study to evaluate participants with solid tumors with a high risk of relapse for incurable disease. No interventional therapy will be administered on this study. Some of the information regarding the participant's tumor analysis may be beneficial to management of their disease. Participants that meet all criteria may be enrolled and leukapheresed (blood cells collected). The participant's cells will be processed and stored for potential manufacture of CAR T-cell therapy upon relapse of their cancer.
