About this study

This is a phase 1 open-label study. The objective of this study is to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of oral administered SHR2285 in healthy subjects

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Ability to understand the trial procedures and possible adverse events, volunteers to participate in the trial, and provides written informed consent.
  • Be able to comply with all the requirements and able to complete the study.
  • Male or female aged between 18 years and 55 years (inclusive) at the date of signed consent form.
  • No clinically significant abnormalities in medical history, general physical examination, vital signs, and laboratory tests.
  • Men and women of childbearing potential (WOCBP) must agree to take effective contraceptive methods and have no plan to have a child from signing the consent form to 16 weeks after IP administration.

Exclusion criteria

  • Receipt of any other investigational drugs or medical devices within 3 months prior to screening (according to the date of signed consent form).
  • History of illicit or prescription drug abuse or addiction within one year of screening, or positive urine drug screen at screening and Day-1. The urine drug screen may be repeated at the discretion of the investigator and the reason for repeat needs to be documented clearly (e.g., suspicion of false positive due to diet).
  • Receipt of any other investigational drugs or medical devices within 3 months prior to screening (from the date of signed consent form).
