Study of CXCR5 Modified EGFR Targeted CAR-T Cells for Advanced NSCLC
Bu Erken Faz 1 (Early Phase 1) çalışma, ileri evre küçük hücreli dışı akciğer kanseri (non-small cell lung cancer, NSCLC) olan yetişkinlerde, C-X-C kemokin reseptörü tip 5 (CXCR5) ile modifiye edilmiş, EGFR hedefli kimerik antijen reseptörü (chimeric antigen receptor, CAR) taşıyan otolog T hücrelerinin damar içi infüzyonunu incelemektedir. Çalışma tek kollu ve açık etiketlidir. Katılım için 18-75 yaş aralığında olmak, histolojik veya sitolojik olarak doğrulanmış ileri evre NSCLC tanısı bulunmak ve tarama işlemleri öncesinde bilgilendirilmiş onam verilmiş olması gerekmektedir.
