An Evaluation of LY007 Cell Injection for r/r B-NHL
Bu çalışma, nüks etmiş veya dirençli B-hücreli non-Hodgkin lenfoma (B-cell non-Hodgkin lymphoma, B-NHL) hastalarında LY007 adlı hücre tedavisini (hücre enjeksiyonu) değerlendirmektedir. Çalışmaya, CD20-pozitif B-NHL tanısı bulunan, daha önce en az iki tedavi almış, 18-70 yaş arası hastalar alınmaktadır. Çalışma Faz 1 aşamasında yürütülmekte ve halen katılımcı almaktadır.
