Oral Vinorelbine and Capecitabine in Advanced HER2-negative Breast Cancer

February 27, 2023 updated by: Cancer Institute and Hospital, Chinese Academy of Medical Sciences

A Doublelet Metronomic Chemotherapeutic Regimen With Oral Vinorelbine and Capecitabine in Advanced HER2-negative Breast Cancer Patients: A Monocentric Retrospective Study in China

This study was a prospective, single-arm, open-label phase II clinical trial conducted at National cancer center in China.

Detailed Description

Metronomic chemotherapy is a relatively low-dose, high-frequency, continuous application of cytotoxic agents. Phase I/II VICTOR-1 studies have shown that the dual oral beat combination of vincristine and capecitabine is highly active and well tolerated in patients with locally advanced or metastatic breast cancer. The long-term efficacy of oral two-metronomic agents (vinorelbine and capecitabine) in Chinese advanced HER-2 negative breast cancer patients stays unclear. The current study was designed to explore the efficacy of oral two-metronomic agents (vinorelbine and capecitabine) in advanced HER-2 negative patient China.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Study group
The eligible patients were enrolled to receive oral metronomic vinorelbine 40 mg on day 1, day 3, day 5 every week (Monday, Wednesday, and Friday) and capecitabine 500mg three times daily (tid) after meals every 3 weeks. Until disease progression or unacceptable toxicity occurred, or the patient refused medication, vinorelbine and capecitabine were administered continuously without drug-free periods over 21-day cycles.
Drug: oral vinorelbine and capecitabine

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Progression-free Survival
Time Frame: At 1 year
1-year progression-free survival (PFS1). Evidence of local recurrence, distant metastasis, or death from any cause within 1 year counted as events in the time-to-event Kaplan-Meier analysis of progression-free survival. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions
At 1 year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Proportion of Confirmed Response, Defined as a Partial Response (PR) or Better
Time Frame: Up to 1 year
Confirmed response will be evaluated using all cycles. The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR Confirmed response will be evaluated using all cycles. The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR
Up to 1 year
