Long-term Clinical Study of CN128 in Thalassemia With Sever Liver Iron Overloaded Patients

Prior treatment

• The patients who can not accept MRI as detection means, such as claustrophobic for MRI, pacemaker, and those using ferromagnetic metal implants.
• Participated in other clinical trials in the four weeks before taking the test preparation, except for non-interventional studies.

Other illness

• Active gastrointestinal disease history (including: gastric ulcer, duodenal ulcer, stomach or esophageal varices, ulcerative colitis, Crohn's disease, gastrointestinal cancer, familial genetic multiple intestinal polyps), and History of gastrointestinal perforation, gastrointestinal surgery that influence drug absorption, and other potential intestinal complications considered by researchers.
• Active infection uncontrolled.
• Autoimmune hemolytic anemia patients.
• Cardiac iron overloaded patients, cardiac magnetic resonance MRI T2\*\<10 ms
• The patients who are allergic or contraindicated to the main ingredients or excipients of CN128 tablets.

Lab values

• Active hepatitis B (HBsAg positive, HBsAb negative) or hepatitis C (HCV antibody positive, detectable HCV RNA, and Alkaline Phosphatase (ALT) beyond normal range)
• ALT or Aspartate Aminotransferase (AST) \> 2.5 × upper limit of normal (ULN), or serum creatinine \> 1.5 × ULN.
• Neutropenia patient (neutrophil count \< 1.5 × 10\^9 / L).
• The patients who are currently taking CYP3A strong inducer or strong inhibitor drugs, or the drug that may extend the QT interval, or the drug that may decrease neutrophil count, but can not temporarily interrupt the use of such drugs.
• Congenital long QT syndrome or known family history of long QT syndrome, QTc interval\>480 ms, clinically significant ventricular or atrial fast arrhythmia.

Other

• Birth planner (including male subjects) within or within 3 months after the end of the trial.
• Pregnant or lactating women.
• Unsuitable to participate in the trial considered by the researchers.

• Thalassemia patients.
• The number of blood transfusion per month ≥1. Or hemoglobin can not be maintained at 90g/L above, if blood transfusions is less than once per month.
• Severe iron overloaded patients (serum ferritin\>2500 µg/L or liver iron concentration (LIC)\>15 mg/g dw) despite prior treatment with at least one iron chelator.
• Patients aged 16 and above.
• Volunteer for the trial and sign the informed consent.
