Summary

This is an open label, multicenter, Phase 1/2 study in approximately eight adults with severe Sickle Cell Disease (SCD). The study will evaluate the safety, tolerability, and efficacy of autologous hematopoietic stem cell transplantation using BIVV003.

Description

Subject participation in this study will be approximately 136 weeks. Enrolled subjects will be asked to participate in a separate long-term follow-up study to monitor the safety and efficacy of BIVV003 treatment for a total of 15 years post-transplant.
