Exclusion criteria: |
1. Known or suspected hypersensitivity to the investigational product or any of its known components; or individuals with a specific history of allergies (e.g., asthma, urticaria, eczema) or those considered to be atopic; 2.

Coagulation abnormalities (International Normalized Ratio [INR] >= 1.5; Activated Partial Thromboplastin Time [APTT] >= ULN + 10 seconds). 12. Positive for Hepatitis B surface antigen (HBsAg) with HBV-DNA > ULN, positive for Hepatitis C virus (HCV) antibody, positive for Human Immunodeficiency Virus (HIV) antibody, or positive for Treponema pallidum antibody. 13. Planned surgery during the trial period. 14. History of alcohol or substance abuse within 2 years prior to screening; or positive urine drug screen or alcohol breath test during screening. 15.

Participation in any other investigational drug trial and receipt of the investigational product within 3 months prior to screening, or within 5 half-lives of the previous investigational product (whichever is longer). 18. Poorly controlled immune-mediated disease(s), or any condition requiring treatment with immunoglobulin, monoclonal antibodies (or derivatives), immunosuppressants, or plasmapheresis, where the washout period prior to dosing is less than 5 half-lives. 19. Female participants of childbearing potential with a positive serum pregnancy test at screening, or who have had unprotected sexual intercourse within 30 days, or who are pregnant or lactating. 20. Unwillingness to comply with the protocol-specified contraceptive methods (see Section 5.4) during the trial and for 3 months after the last dose of the investigational product. 21. Inability to provide Apolipoprotein E (ApoE) genotyping results and unwillingness to undergo ApoE genotyping. 22. Inability to tolerate PET/MRI procedures or presence of contraindications to PET/MRI, including but not limited to: incompatible pacemakers, aneurysm clips, artificial heart valves, ear implants, or the presence of metal fragments in the eyes, skin, or body that may contraindicate MRI scanning; known hypersensitivity to florbetapir F18; or claustrophobia. 23.

随机方法(请说明由何人用什么方法产生随机序列): |
参与者的随机编号由非盲统计师用随机的方法,应用SAS 9.4或以上版本软件根据随机数字表在计算机上模拟产生随机分配表。 专门的统计人员将随机分配表配置入交互式网络应答系统(IWRS)。研究者或者其指定的研究人员将筛选合格参与者的基本信息传递给IWRS系统,由IWRS系统为具备入选资质的参与者分配随机号。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
The random codes for participants were generated by a non-blinded statistician using a computerized random number generator based on a random number table, implemented with SAS software version 9.4 or higher to produce the randomization schedule. Dedicated statistical personnel then configured this randomization schedule into the Interactive Web Response System (IWRS). The investigator or their designated research staff submitted the basic information of eligible screened participants to the IWRS, which subsequently assigned random numbers to qualified participants. |
