SHR9549 in ER Positive HER2 Negative Advanced Breast Cancer

Phase 1
Terminated
Conditions
ER+ HER2- Advanced Breast Cancer
Interventions
Registration Number
NCT03596658
Lead Sponsor
Jiangsu HengRui Medicine Co., Ltd.
Brief Summary

This is a phase 1 open label multicentre study of SHR9549 administered orally in patients with advanced estrogen receptor (ER) positive human epidermal receptor 2 (HER2) negative breast cancer. The study design allows an escalation of dose with intensive safety monitoring to ensure the safety of patients. The study will determine the maximum tolerated dose(MTD). In addition, expansion cohort(s) at potential therapeutic dose(s) in patients will be enrolled to further determine the safety, tolerability, pharmacokinetics and biological activity of SHR9549.

Detailed Description

A Phase I, Open-Label, Multicentre Study to Assess the Safety, Tolerability, Pharmacokinetics and Preliminary Anti-tumour Activity of Ascending Doses of SHR9549 in Women with Estrogen Receptor (ER) Positive Human Epidermal Receptor (HER-2) Negative Advanced Breast Cancer
