   * To evaluate the safety and efficacy of long-term orally administration of CN128 in thalassaemia patients with blood transfusion dependent and aged 16 and above.
2. Design:

   * The study is designed as a single arm and opened phase IIa clinical trial, so as to investigate the safety and efficacy of CN128.
   * A total of 50 eligible subjects are planned to be enrolled, and orally administration of CN128 for 24 weeks or 48 weeks according to the administration plan. The treatment period is from day 0 to 24 weeks, and the extended treatment period was from 25 weeks to 96 weeks.
   * Administration plan:

   (1)0 day\~48 weeks： The trial will start with the lower dose of CN128 (10 mg/kg body weight \[bw\], bid) for two weeks, then the subjects will return to the study center. If no unacceptable toxicity associated with CN128 is found, the subjects will be given the higher dose (15 mg/kg body weight \[bw\], bid). If unacceptable toxicity associated with CN128 is found, the subjects will be suspended or stopped administration. If the adverse event turns to normal or abnormal but no clinical significance after suspension administration, the subjects will be given the lower dose of CN128 (10 mg/kg body weight \[bw\], bid).

   After taking CN128 at 15 mg/kg, if unacceptable toxicity associated with CN128 is found, the dosage will be reduce to 10 mg/kg. If no symptoms appear, the dose can be increased to 15 mg/kg. If the unacceptable toxicity related to CN128 still occurs, the subjects will be suspended or stopped administration. If the adverse event turns to normal or abnormal but no clinical significance after suspension administration, the subjects will be given the lower dose of CN128 (10 mg/kg body weight \[bw\], bid). The dose will be assessed once every two or four weeks.

   Subjects' medication status, uncomfortable symptoms, concomitant medication or non-drug therapy were recorded daily.

   (2)49 weeks\~96 weeks： Subjects who have completed 48 weeks of treatment may continue dosing at the original dose until the end of the study or withdraw early if they do not experience intolerable toxicity associated with CN128 tablets and have fair efficacy (≥20% elevation on MRI T2\*) and if, in the judgment of the investigator, the benefits outweigh the risks.

   Subjects who have completed 48 weeks of treatment, who have not experienced intolerable toxicity associated with CN128 tablets, but who have been assessed by the investigator as having poor efficacy (\<20% elevation of MRI T2\*) and in the judgment of the investigator the benefit outweighs the risk, may, with the subject's consent, have the dosage increased at the additional visit or the established most recent visit to 15 mg/kg in the morning and 20 mg/kg in the evening, with an assessment made at 2 weeks of dosing：

   If no relevant intolerable toxicity occurs, the dose may continue to be increased to 20 mg/kg bid and assessed after 2 weeks of dosing:
   1. If no relevant intolerable toxicity occurs, the 20 mg/kg bid dose may be administered until the end of the study or early withdrawal (daily dose 40 mg/kg/d);
   2. If relevant intolerable toxicity occurs, the dose may be reduced to 15 mg/kg in the morning and 20 mg/kg bid in the evening until the end of the study or early withdrawal (daily dose 35 mg/kg/d).

   If relevant intolerable toxicity occurs, the dose may be reduced to 15 mg/kg bid until the end of the study or early withdrawal (daily dose 30 mg/kg/d).
