Gene Editing For Sickle Cell Disease (NCT06506461)

St. Jude Autologous Genome Edited Stem Cells For Sickle Cell Disease-1

🟢 Recruiting Phase1 💊 Investigational Drug / Biologic Sponsor: St. Jude Children's Research Hospital

🩺 Plain-English Summary (8th-Grade Level)

This study is being done to test the safety of a new treatment called gene editing in Sickle Cell Disease (SCD) patients and to see if a single dose of this genetically modified cellular product will increase the amount of a certain hemoglobin called fetal hemoglobin (HbF) and help reduce the symptoms of SCD. Primary Objective * To assess the safety of autologous infusion of clustered regularly interspaced palindromic repeats (CRISPR)/ CRISPR associated protein (Cas9)-edited CD34+ hematopoietic stem and progenitor cells (HSPCs) in patients with severe SCD. Secondary Objective * To assess the efficacy autologous infusion of CRISPR/Cas9 genome-edited CD34+ HSPCs into patients with severe SCD.

Who can join: To join this study, participants generally need to meet the listed inclusion criteria (7 items) and avoid the listed exclusions (23 items).

Location: St. Jude Children's Research Hospital — Memphis, Tennessee

Age range: 18 Years to 24 Years

Instant Checklist

Check every box below. If you can check all of them, you may meet the study's basic screening requirements (final eligibility is confirmed by the site team).

Usually NOT eligible if any of the following apply:

  • Exclusion Criteria:
  • Availability of an human leukocyte antigen (HLA)-matched sibling who is willing and able to donate an appropriate graft for hematopoietic cell transplantation (HCT).
  • Karnofsky or Lansky performance score \< 80.
  • Pregnant, as confirmed by positive serum or urine pregnancy test within 14 days before enrollment (if female).
  • Breastfeeding.
  • Uncontrolled (undergoing appropriate treatment and with progression of clinical symptoms) or clinically significant bacterial, viral, or fungal infections within 1 month before enrollment.
  • Patients with confirmed Hepatitis B or Hepatitis C infections.
  • Patients with confirmed seropositivity or positive nucleic acid amplification test (NAAT) for human immunodeficiency virus (HIV) or human T-cell lymphotropic virus (HTLV).
  • Patients with a history of stroke.
  • Serum conjugated (direct) bilirubin \> 2× the upper limit of normal for age, or serum alanine transaminase (ALT) \> 3× the upper limit of normal for age as per the local laboratory. Participants with hyperbilirubinemia or elevated aspartate aminotransferase (AST) as the result of hyperhemolysis, or with a severe drop in hemoglobin post blood transfusion, are not excluded as long as these values downtrend and return to acceptable limits subsequently.
  • Left ventricular shortening fraction \< 25% or ejection fraction \< 45% by echocardiogram.
  • Estimated creatinine clearance less than 60 mL/min/1.73m\^2.
