Interleukin-15 Armored Glypican 3-specific Chimeric Antigen Receptor Expressed in T Cells for Pediatric Solid Tumors
Bu çalışma, çocuklarda GPC3 pozitif solid tümörler (solid tumors) için hastanın kendi T hücrelerinin genetik olarak değiştirildiği AGAR T hücreleri adlı bir hücre tedavisini (CAR-T) değerlendiriyor. Katılım için 1-21 yaş arası, GPC3 pozitif tümörü olan çocuklar aranmaktadır. Çalışma Faz 1 aşamasında yürütülmektedir; şu an katılımcı almamakta ancak devam etmektedir (active, not recruiting).
