简要总结
Only enrolling in Canada.
The purpose of this study is to identify the highest dose of GCAR1, a chimeric antigen receptor (CAR-T) cell therapy, that can be tolerated without causing very severe side effects, and to see what effects GCAR1 has on selected cancers
详细描述
GCAR1 is a type of CAR-T cell therapy that is designed to identify a protein (GPNMB) that is present on the cells of certain types of cancer. Laboratory tests have shown that GCAR1 helps the immune system recognize cancer cells and may help slow down cancer growth.
The purpose of this study is to find out what effects the new treatment, GCAR1 has on certain cancers. This study will test increasing doses of GCAR1 in participants with alveolar soft part sarcoma (ASPS), triple negative breast cancer (TNBC), and renal cell carcinoma (RCC) expressing high levels of the GPNMB protein, to establish recommended doses for further testing.
