Brief summary
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of HS-10518 in healthy adult premenopausal females in China.
Detailed description
This is a double-blind, placebo-controlled, multiple-dose, single-center phase 1 study in Chinese healthy premenopausal females aged 18-45 years with a regular menstrual cycle (26-32 days). The main purpose of the study is to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of HS-10518, a gonadotropin-releasing hormone antagonist. About 48 eligible female subjects will be enrolled. The study contains four cohorts. In each cohort, participants will be randomly assigned to the HS-10518 arm or the placebo arm in a 3:1 ratio. HS-10518/matching placebo will be administered from Day 1 to Day 7. The study duration of each participant is up to \ 10 weeks.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of Adverse Events (AE) as assessed by CTCAE v4.0 | From screening to day 16 | Assessment of safety and tolerability of multiple-dose HS-10518 in healthy female subjects in terms of the frequency, severity and causality of AEs, serious adverse events (SAEs) and AEs leading to study discontinuation. CTCAE v4.0 will be used for classification and severity determination. |
| Assessment of safety and tolerability of HS-10518 in terms of the frequency, severity and causality of AEs, serious adverse events (SAEs) and AEs leading to study discontinuation. | From screening to day 16 | Incidence of any markedly abnormal standard vital sign measurements is collected throughout study. |
| Incidence of clinically significant abnormal findings in 12-lead electrocardiogram (ECG) | From screening to day 16 | Incidence of any clinically significant abnormal findings in 12-lead ECG is collected throughout study. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Plasma pharmacokinetic (PK) parameter: Maximum plasma concentration (Cmax) | Day 1 (after the first dose) and Day 7-10 (after the last dose) | The maximum observed plasma concentration of HS-10518. |
| PK parameter :Time of maximum observed plasma concentration (Tmax) | Day 1 (after the first dose) and Day 7-10 (after the last dose) | Time of the maximum observed plasma concentration of HS-10518. |
| PK parameter: Area under the concentration-time curve from time 0 to the last quantifiable concentration (AUC0-t) | Day 1 (after the first dose) and Day 7-10 (after the last dose) | Area under the concentration-time curve from time 0 to the last quantifiable concentration of HS-10518. |
