Gene editing offers hope for blood disorder patients
NCT ID NCT06024876
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase study tested a new gene-edited stem cell treatment (CS-101) in 5 people with beta-thalassemia, a severe blood disorder requiring regular blood transfusions. The goal was to see if the treatment is safe and can help patients produce healthy red blood cells, potentially reducing or eliminating the need for transfusions. Participants received their own genetically modified stem cells after a conditioning regimen.

Key Inclusion Criteria: * 6 to 35 years old(inclusive) male or female subjects at the time of informed consenting * Diagnosis of β-thalassemia, genotypes include but are not limited to β+β0,βEβ0,β0β0, etc * History of at least≥8 units/year of packed RBC transfusions in the prior 12 months prior to the screening period * Generally in good condition, Karnofsky performance score≥60 points for subjects≥16 years old at the time of autologous hematopoietic stem cell collection, or Lansky Play-Performance score≥60 points for subjects under 16 years old, or equivalent clinical evaluation as the investigator site's common practice Key Exclusion Criteria: * Treatment with other investigational medications or other experimental interventions 30 days prior to signing informed consent or within 6 half-lives of the drug, whichever is longer. * Subjects who have received or are receiving thalidomide and/or Luspatercept, when their drug-drug interaction on the efficacy and safety of CS-101 cannot be ruled out, unless at least there are 3 test results showing the total hemoglobin level before transfusion is below 9g/dL in the past 6 months before screening. * Previously received allogeneic hematopoietic stem cell transplantation or gene(edited) therapy. * Subjects have available related fully matching donors and are eligible and prepared for allogeneic hematopoietic stem cell transplantation. * Those with active infections, including but not limited to: HIV, hepatitis B, hepatitis C, cytomegalovirus, Epstein-Barr virus and treponema pallidum test positive, or known tuberculosis, parasitic infection, etc. who are judged by the investigator to be unsuitable to participate in this study. * Echocardiography results with ejection fraction below 45%. * Advanced liver disease, defined as: Aspartate aminotransferase (AST), alanine aminotransferase (ALT) \>3 × upper limit of normal (ULN) or: Baseline International Normalized Ratio (INR) \>1.5 × ULN. * MRI during the screening period showed heavy iron overload and is judged by the investigator to be unable to participate in the study.
