Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Recombinant human thrombopoietin for injection (rhTPO)

Experimental: Healthy Caucasian volunteers - Single abdominal subcutaneous injection of the study drug will be given on D1. The administration and follow-up observation period will be 29 days (D1\~D29). Participants may be discharged at D7 at the judgment of the investigator. PK blood samples will be collected from D-1 to D14, tolerance and safety will be observed from D1 to D29, and blood samples for PD and anti-drug antibody (ADA) will be collected from screening to D29. After completion of relevant assessments on D29, participants will be considered as having completed this study.

Eligibility
Key inclusion criteria
* Participants are eligible to be included in the study only if all of the following criteria apply:

1. Healthy Caucasian adult male and female participants aged 18-50 years (inclusive) at the time of informed consent. Caucasian is defined as of European, Middle Eastern, or North African descent.
2. Male participants weighing no less than 50 kg. Female participants should not weigh less than 45 kg.
3. Body mass index (BMI) within the range 18.0 to 32.0 kg/m2 (inclusive). Note: BMI = weight [kg] / (height [m])2
4. Participants are in good general health as determined by the investigator, based on a medical evaluation including medical history, vital signs, physical examination, 12-lead electrocardiogram, clinical safety laboratory tests; Note: Any results outside of the reference range at screening or baseline may be repeated once per the Investigator's discretion for the purpose of further determining eligibility.
5. Platelet counts must be within the normal range; measurements can repeat once for verification, if necessary.
6. Women of childbearing potential (WOCBP, see section 5.3.3) must have a negative serum or urine pregnancy test prior to the start of study drug and must not be breastfeeding, lactating or planning pregnancy during the study period. WOCBP who are not exclusively in same-sex relationships and males with partners of child-bearing potential must agree to use adequate contraception from signing the informed consent until 3 months after completion of the study. In addition, females must not donate ova (eggs) and males must not donate sperm from signing the informed consent until 3 months after completion of the study;
7. Negative for COVID-19 based on the nasopharyngeal or oropharyngeal swab with the method of real-time reverse transcription-polymerase chain reaction (RT-PCR) at Screening and Day-1.
