About the study

This is a single-arm, open-label, multi-site, single-dose Phase 1/2 study in up to 12
subjects 18 to 35 years of age with severe sickle cell disease (SCD). The study will evaluate
the safety and efficacy of autologous CRISPR-Cas9 Modified CD34+ Human Hematopoietic Stem and
Progenitor Cells (hHSPCs) using CTX001.

study participation requirements

– Subjects ≥ 18 and ≤ 35 years of age

– Diagnosis of severe sickle cell disease as defined by:

– Documented βS/βS genotype

– History of at least two severe vaso-occlusive crisis events per year for the previous
two years prior to enrollment

– Eligible for autologous stem cell transplant as per investigators judgment

Key

study participation exclusions

– An available 10/10 human leukocyte antigen (HLA)-matched related donor

– Prior hematopoietic stem cell transplant (HSCT)

– Clinically significant and active bacterial, viral, fungal, or parasitic infection

Other protocol defined inclusion/exclusion criteria may apply
