study description
Brief Summary

This is a single-center phase II study designed to evaluated the efficacy and safety of fulvestrant in combination with oral vinorelbine in hormone receptor-positive advanced breast cancer

Condition or Disease: Hormone Receptor Positive Advanced Breast Cancer
Intervention/treatment: Drug: fluvestrant + oral vinorelbine
Phase: Phase 2
Detailed Description

This is a single-group, single-center phase II trial. Patients with
hormone-receptor-positive, Her2-negative recurrent or metastatic breast cancer who had not
previously received any systemic antitumor therapy for advanced disease were treated with
fulvestrant combined with oral vinorelbine as a first-line regimen. Key issues to be
addressed in this study: to observe and evaluate the efficacy and safety of fulvestrant
combined with oral vinorelbine in the treatment of hormone-receptor-positive and
HER2-negative advanced breast cancer. Thirty patients are planned to be enrolled.


study design
Study Type: Interventional
Estimated Enrollment : 30 participants
Intervention Model : Single Group Assignment
Masking: None (Open Label) ()
Primary Purpose: Treatment
Official Title: Phase II Study of Fluvestrant Combined With Oral Vinorelbine in Hormone Receptor-positive Advanced Breast Cancer
Actual Study Start Date: December 2017
Estimated Primary Completion Date: December 2020
Estimated Study Completion Date: December 2020

Arms and interventions
Arm Intervention/treatment
Experimental: Single arm
Fluvestrant in combination with oral Vinorelbine Fluvestrant: administered at a dose of 0.5g once im every 28 days. Vinorelbine: administered at a dose of 60mg/kg once a week for 3 weeks p.o. every 28 days.
Drug: fluvestrant + oral vinorelbine
Eligible patients will be treated with the fluvestrant + oral vinorelbine regimen until the disease progresses or intolerable toxicity
outcome measures
Primary Outcome Measures: 1. Progression-free survival (PFS) [ Time Frame: approximately 1.5 years ]
PFS will be defined as the time from first dose of study drug until documentation of disease progression or death from any cause
Secondary Outcome Measures: 1. Objective response rate (ORR) [ Time Frame: approximately 6 months ]
The ORR will be calculated as the proportion of patients in the Efficacy Evaluable patient Set who achieve complete response (CR) and partial response (PR)
2. Incidence and Severity of adverse events [ Time Frame: approximately 1.5 years ]
hematologic toxicity,hepatotoxicity and so on

Eligibility Criteria

- Patients who are pregnant , breastfeeding ,or refuse to use adequate contraception during the course of participation.

- Need to concurrent other cancer therapy(other than palliative care for non-target lesions).

- Other ineligible conditions according to the researcher's judgment.
