About this trial

This study is an open-label, non-randomized, single-dose Phase 1/2 trial involving around 85 adult and pediatric participants aged between 2 and 50 years with sickle cell disease (SCD). It aims to assess the effectiveness of hematopoietic stem cell transplantation (HSCT) using BAH243 for SCD.

Eligibility criteria

Qualifiers

Have a diagnosis of SCD, with either βS/βS, βS/β0, or βS/β+ genotype.

Be ≥2 and ≤50 years of age at time of consent.

Weigh a minimum of 6 kg.

Have a Karnofsky performance status of ≥60 (≥16 years of age) or a Lansky performance status of ≥60 (<16 years of age).

Disqualifiers

Subjects for whom allogeneic hematopoietic stem cell transplantation (allo-HSCT) is medically appropriate per PI judgment and a willing, human leukocyte antigen (HLA)-matched related hematopoietic stem cell donor is available.

Severe cerebral vasculopathy, defined by any history of overt ischemic or hemorrhagic stroke, a history of abnormal transcranial Doppler (TCD) or TCD imaging (TCDI) for subjects ≤ 16 years of age (e.g. TCD velocity >200 cm/sec) requiring ongoing chronic transfusions, a Screening TCD or TCDI velocity > 200 cm/sec (central read), a Screening MRA showing > 50% stenosis or occlusion in the circle of Willis (central read), or a Screening MRA showing the presence of Moyamoya (central read).

Positive for presence of human immunodeficiency virus type 1 or 2 (HIV-1 or HIV-2), hepatitis B, hepatitis C, human T-lymphotropic virus-1 (HTLV-1), active syphilis.

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