Research Sponsored by Donald B. Kohn, M.D.
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial Must have
Inadequate clinical response to hydroxyurea (HU), defined as any one of the following outcomes, while on HU for at least 3 months:
- 2 or more acute sickle pain crises requiring hospitalization
Timeline
Screening 3 weeks
Treatment Varies
Follow Up up to 24 months
Awards & highlights
Study Summary
This trial will test a new treatment for sickle cell disease that uses the patient's own blood cells.
Who is the study for?
Adults with severe sickle cell disease who have had complications like pain crises, stroke, or acute chest syndrome despite treatment can join this trial. They must not be pregnant, have HIV/HCV/HTLV-1/hepatitis B/Cancer, and should not have a suitable sibling donor for transplant.Check my eligibility
What is being tested?
The trial is testing a gene therapy where patients' own blood stem cells are modified with the βAS3-FB vector to potentially treat sickle cell disease. It's in Phase I to check safety and initial effectiveness.See study design
What are the potential side effects?
Potential side effects may include reactions at the infusion site, immune response against the modified cells, or other unforeseen issues due to genetic modification of blood cells.
