Anti-CD19 CAR-Engineered NK Cells in the Treatment of Relapsed/Refractory Acute Lymphoblastic Leukemia
Bu çalışma, nükseden ya da tedaviye dirençli CD19 pozitif akut lenfoblastik lösemi (acute lymphoblastic leukemia; bir kan kanseri) olan hastalarda, bağışıklık hücrelerinin gen mühendisliğiyle donatıldığı bir hücresel tedaviyi (CAR-NK-CD19 hücreleri) incelemektedir. Doz keşif aşamasında 3 yaş ve üzeri hastalar katılabilmekte olup hastaların ana organ işlevlerinin yeterli olması beklenmektedir. Çalışma Faz 1 aşamasında yürütülmüş ve tamamlanmıştır.
