Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Lab values
- 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.
Who the study is looking for
- 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
