9. Female participants of childbearing potential must have a negative serum pregnancy test within -7 days of randomization and must be willing to use very efficient barrier methods of contraception or a barrier method plus a hormonal method starting with the screening visit through 60 days (about 5 drug half-life + menstrual cycle) after the last dose of SHR-1210. Male participants with a female partner(s) of child-bearing potential must be willing to use very efficient barriermethods of contraception from screening through 120 days (about 5 drug half-life + sperm depletion cycle) after the last dose of SHR-1210.
10. Subjects should be voluntarily participate in clinical studies and informed consent should be signed.
