The Pharmacokinetic(PK)/Pharmacodynamics(PD) Study of SHR7280 Tablets in Premenopausal Subjects With Endometriosis.

Phase 1
Completed
Conditions
Endometriosis
Interventions
Drug: Placebo oral tablet
Registration Number
NCT04417972
Lead Sponsor
Jiangsu HengRui Medicine Co., Ltd.
Brief Summary

The primary objective of this study is to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of SHR7280 tablets in premenopausal subjects with endometriosis. In addition, this study will provide information on efficacy of SHR7280 tablets in premenopausal subjects with endometriosis.

Detailed Description

Endometriosis is a common disease, affecting 5-10% of women of reproductive age . It is an estrogen-dependent and estrogen-driven disease and so hormonal manipulation and suppression of estrogen production form the basis of the majority of medical treatment. The primary objective of this study is to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of SHR7280 tablets in premenopausal subjects with endometriosis. In addition, this study will provide information on efficacy of SHR7280 tablets in premenopausal subjects with endometriosis.
