Официальное название
A Phase I/II Study of Nula-cel in Autologous CD34+ Hematopoietic Stem Cells to Convert HbS to HbA for Treating Severe Sickle Cell Disease
Обзор
This study is a first-in-human, single-arm, open-label Phase I/II study of nula-cel in approximately 15 participants, diagnosed with severe Sickle Cell Disease. The primary objective is to evaluate safety of the treatment in this patient population, as well as preliminary efficacy and pharmacodynamic data.
Подробное описание
Participants diagnosed with severe SCD will receive nula-cel via IV infusion following myeloablative conditioning in an autologous HSCT setting.
