Eligibility
Inclusion criteria
* Subjects fully understand the purpose, content, process, and potential adverse events of the trial, voluntarily participate in the trial, and sign an informed consent form before any trial procedure begins. * Weight: 60\~72kg; Body mass index (BMI) ≥ 19 and ≤ 26 kg /m² for healthy Chinese male subjects. * Fasting LDL-C level\<4.1mmol/L. * Fasting triglycerides\<3.42mmol/L. * Required to voluntarily adopt effective contraceptive measures as specified in the protocol throughout the entire trial period and within 3 months after receiving the investigational product, and avoid sperm donation.
Exclusion criteria
* 12 months prior use of PCSK9 inhibitors treatment. * Allergic to the components of Ebronucimab and any monoclonal antibodies. * History of important organ transplantation (such as heart, lung, liver, kidney, etc.). * Abnormal vital signs during screening period and before randomization. * Investigators believe that other factors may disqualify individuals from participating in the trial.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Maximum (peak) plasma concentration (Cmax) | Baseline till last follow-up visit (up to day 43) | Assess the Cmax of Ebronucimab. |
| Area under curve (AUC) | Baseline till last follow-up visit (up to day 43) | Assess the AUC of Ebronucimab. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of adverse events (AE) | After the first administration till last follow-up visit (up to day 43) | An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product temporally associated with the use of study treatment, whether or not considered related to the study treatment. |
| Immunogenicity index | Baseline till last follow-up visit (up to day 43) | Number and percentage of subjects with detectable anti drug antibodies (ADA) and neutralizing antibodies (Nab) after treatment. |
| Proprotein convertase subtilisin/kexin type 9 (PCSK-9) concentration | Baseline till last follow-up visit (up to day 43) | Percentage change in PCSK-9 concentration compared to baseline. |
| Serum low-density lipoprotein cholesterol (LDL-C) concentration | Baseline till last follow-up visit (up to day 43) | The change value and percentage of serum LDL-C concentration compared to baseline. |
