Trastuzumab and Vinorelbine - Cohort A

Trastuzumab and Vinorelbine - Main Cohort

Arm Description

Cycle 1: Patients received trastuzumab 8 mg/kg intravenously (IV) on day 1 and vinorelbine 25 mg/kg IV on days 1, 8 and 15 of each 21 day cycle Cycles 2+: Patients received trastuzumab 6 mg/kg IV on day 1 and vinorelbine 25 mg/kg IV on days 1, 8 and 15 of each 21 day cycle Patients were treated until disease progression or unacceptable toxicity. Eligibility required patients to have HER2 amplification by fluorescence in situ hybridization (FISH) (mean ratio > 2.0). The CTC tests of the first 11 patients were done at DFCI. The study team then decided to proceed with a different CTC test performed outside of DFCI. Because the method of CTC isolation was different from that performed by DFCI, the first 11 patients were placed into a separate cohort (Cohort A) and the remaining 20 patients represented the main cohort.

Outcomes

Primary Outcome Measures

Objective Response Rate (ORR)

ORR was defined as the percentage of patients achieving complete response (CR) or partial response (PR) based on RECIST 1.1 criteria on treatment. Per RECIST 1.1 for target lesions: CR is complete disappearance of all target lesions and PR is at least a 30% decrease in the sum of longest diameter (LD) of target lesions, taking as reference baseline sum LD. PR or better overall response assumes at a minimum incomplete response/stable disease (SD) for the evaluation of non-target lesions and absence of new lesions.

Secondary Outcome Measures

Clinical Benefit Rate (CBR)

CBR was defined as achieving complete response (CR), partial response (PR), or stable disease (SD) for 24 weeks or longer based on RECIST 1.1 criteria on treatment. Per RECIST 1.1 for target lesions: CR is complete disappearance of all target lesions and PR is at least a 30% decrease in the sum of longest diameter (LD) of target lesions, taking as reference baseline sum LD. PD is at least a 20% increase in sum LD of target lesions (smallest sum LD reference), new lesions, and/or unequivocal progression of existing non-target lesions. Stable disease (SD) is defined as any condition not meeting the above criteria. SD needed to be a minimum 24 weeks in duration

Progression-Free Survival (PFS)

PFS based on the Kaplan-Meier method is defined as the duration of time from study entry to documented disease progression (PD) requiring removal from the study or death. Per RECIST 1.1 for target lesions: PD is at least a 20% increase in sum LD, taking as reference the smallest sum on study with at least 5 mm absolute increase. For non-target lesions, progression-free means no new lesions or unequivocal progression on existing non-target lesions or not evaluated.

Baseline Level of Circulating Tumor Cells (CTCs)

CTCs levels were determined based on established methods.

5. Study Description

Brief Summary

The purpose of this research study is to see what effects trastuzumab in combination with vinorelbine has on breast cancer when the participant has circulating tumor cells that are positive for the protein called HER2. Trastuzumab is an FDA approved drug that targets HER2. The drug combination of trastuzumab and vinorelbine is an effective treatment for patients with breast cancers that are positive for HER2. This trial seeks to determine if the combination can also benefit participants whose original breast cancer was HER2 negative but whose circulating tumor cells are HER2 positive.

Detailed Description

OBJECTIVES: Primary To assess the objective response rate (ORR) of trastuzumab and vinorelbine in patients with metastatic breast cancer with HER2 negative primary tumors and HER2 positive circulating tumor cells. Secondary To describe the number of CTCs and the CTCs characteristics before and after therapy, and to explore the correlation of these findings with response. To further characterize the safety and tolerability. To evaluate progression-free survival. To evaluate clinical benefit rate [complete response (CR)+partial response (PR)+stable disease (SD)>24 weeks]. Exploratory To determine the clinical feasibility of high-throughput mutation profiling on circulating tumor cells (CTCs).
