  • Subjects can walk independently or receive outpatient follow-up with assistive devices (wheelchairs, walkers or crutches), while the subject's vision and hearing (allowing glasses and / or hearing aids) do not affect the follow-up procedure;
  • The subject has an identified and reliable caregiver who must also meet the following conditions:
  • (1) In the hospital, caregiver can independently read and understand relevant research documents, and can do necessary communication with the investigator; (2) Caregiver can follow clinical research procedures and ensure that accurate information about the status of the subject can be provided during the study; (3) Caregiver live with the subject; or take care of the subject no less than 3 days a week and no less than 2 hours a day; 10. Female subjects with fertility (including women of childbearing age and women less than 1 year after menopause) were required to take effective contraception throughout the study. At the same time, urine pregnancy tests were negative during screening.
