Brief Summary

The mechanism of action of cidabenamide and the advantages of vincristine metronomic chemotherapy make it possible to combine the two drugs. Therefore, it is necessary to conduct a prospective study to investigate the value of chidamide in combination with vincristine metronomic treatment for triple-negative breast cancer.

Detailed Description

The mechanism of action of cidabenamide and the advantages of vincristine metronomic chemotherapy make it possible to combine the two drugs. Therefore, it is necessary to conduct a prospective study to investigate the value of chidamide in combination with vincristine metronomic treatment for triple-negative breast cancer.The current study was designed to explore the efficacy of oral two-metronomic agents (chidamide in combination with vincristine) in advanced triple-negative patient in China.

GroupInterventionDescription
Study groupChidamidePhase Ib: The dose of vincristine administered in this phase is 40 mg on days 1,3,5 of each cycle. The timepoint for chidamide dosing in this phase is twice weekly, i.e., dosing on days 1,4,8,11,15,18 of each cycle. Take 30 minutes after a meal. Phase II: This phase is based on the MTD/RP2D determined in phase I. The phase II expansion group study was conducted. Vincristine is administered at a dose of 40 mg on days 1,3,5 of each cycle. Chidamide was administered at a dose of MTD/RP2D twice a week on days 1,4,8,11,15 and 18 of each cycle. It is to be taken 30 minutes after a meal.
Primary Outcome Measures
NameTimeMethod
Progression-free SurvivalAt 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

Secondary Outcome Measures
NameTimeMethod
Number of Patients With Clinical Responses (Phase I)Up to 1 year

The number of patients with clinical responses (CR, VGPR, PR, or minimal response \[MR\]) will be summarized by stage.

Overall Toxicity RateUp to 1 year

The overall toxicity rates (percentages) for grade 3 or higher adverse events considered at least possibly related to treatment are reported below by stage for Phase I patients.
