About this trial

This is an interventional treatment trial for Sickle Cell Disease focused on measuring Gene Editing, Sickle Cell, Severe Sickle Cell

Eligibility Criteria

18 Years - 35 Years (Adult)All SexesDoes not accept healthy volunteers

Key Inclusion Criteria Include:

  1. Age ≥18 years to ≤35 years for the initial sentinel cohort; for subsequent enrollment patients from ≥12 years up to ≤35 years may be enrolled only upon approval by FDA.
  2. Documented diagnosis of sickle cell disease with βS/βS, βS/β0, or βS/β+ genotypes.
  3. Severe SCD defined by the occurrence of at least 4 severe VOCs in the 24 months prior to screening despite receiving hydroxyurea or other supportive care measures

Key Exclusion Criteria Include:

  1. HbF levels >20%, obtained at the time of screening on or off hydroxyurea therapy
  2. Previous receipt of an autologous or allogeneic HSCT or solid organ transplantation
  3. Available and willing matched sibling donor
  4. Definitive diagnosis of moyamoya syndrome based on screening brain MRA
  5. History of overt stroke

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

BEAM-101

Arm Description

BEAM-101 manufactured with autologous CD34+ hematopoietic stem cells collected by plerixafor mobilization and edited ex vivo. No maximum dose has been set for BEAM-101; all of the gene edited cells that pass release specifications will be administered to the patient. BEAM 101 will be administered as a single dose by IV infusion.

Outcomes

Primary Outcome Measures

Change in annualized number of severe VOCs (Vascular-occlusive Crisis) relative to baseline
Proportion of patients with successful neutrophil engraftment
Time to neutrophil engraftment
Time to platelet engraftment
Transplant-related mortality within 100 days after beam-101 treatment
Safety and tolerability assessments based on frequency, severity and seriousness of adverse events (AE's)

Secondary Outcome Measures

Proportion of patients experiencing at least 75% reduction in annualized rate of severe VOCs
Proportion of patients experiencing no severe VOCs
Change in annualized number of hospitalizations for VOCs
Change in annualized duration of hospitalizations for VOCs
Change in RBC transfusions per month and per year for SCD-related indications
Change in total Hgb (g/dL) concentration over time
Proportion of patients with HbF ≥30%, for at least 3 months
Change in lactate dehydrogenase (LDH) over time
Change in total bilirubin over time
Change in free Hgb over time
Change in haptoglobin over time
Change in reticulocyte count over time
