Her2 Chimeric Antigen Receptor Expressing T Cells in Advanced Sarcoma
Bu Faz 1 (Phase 1) çalışma, sarkom (sarcoma) adı verilen bir kanser türü olan ve mevcut tedavilerden yeterli yanıt alamayan hastalarda, hastanın kendi T hücrelerinin HER2'yi tanıyacak şekilde genetik olarak değiştirilmesine dayalı bir gen transferi yaklaşımını incelemektedir. Yaklaşım, antikorların hedefe bağlanma özelliği ile T hücrelerinin (T lenfositler) hücreleri öldürme yeteneğini birleştirmektedir; çalışmada ayrıca fludarabin (Fludara) ve siklofosfamid (Cytoxan) kullanılmaktadır. Katılım için dirençli HER2-pozitif sarkom veya metastatik HER2-pozitif osteosarkom tanısı, Karnofsky/Lansky skorunun 50 ve üzeri olması ve bilgilendirilmiş onam gerekmektedir.
