NCT ID: NCT05186545

Last Updated: 2022-09-02

Basic Information

• Recruitment Status: UNKNOWN
• Clinical Phase: PHASE2
• Total Enrollment: 63 participants
• Study Classification: INTERVENTIONAL

Brief Summary

This is a prospective, single center, single arm phase II study designed to explore the efficacy and safety of surufatinib + fulvastrant + chidamide combinational treatment in HR positive breast cancer refractory to endocrine therapy.

Detailed Description

This is a prospective, single center, single arm phase II study. In the safety lead-in stage, 6 subjects will be recruited and administered with surufatinib 250 mg/d, QD PO; Fulvestrant 500mg, im, Q4W; Chidamide 30mg, PO, BIW, with four weeks as a cycle. DLTs of the 6 subjects will be evaluated in the first cycle to determine the recommended dosage of combinational therapy. Then 57 subjects will be recruited and administered with the triplet regimen to explore the efficacy and safety of combinational treatment.
