Trial Outcomes & Findings for Capecitabine, Cyclophosphamide, Lapatinib Ditosylate, and Trastuzumab in Treating Patients With HER2-Positive Metastatic Breast Cancer (NCT NCT01873833)

NCT ID: NCT01873833

Last Updated: 2023-10-05

Results Overview

PFS was defined as duration of time from the first dose of study drug to the first documentation of Progressive Disease (PD) by investigator assessment using RECIST 1.1 or death on study due to any cause on or before the data cutoff date, whichever occurred first. PD: \>=20% increase (\>=5 mm absolute increase) in the sum of target lesion measurements, compared to the smallest sum on study (including baseline), or unequivocal progression of non-target lesions, evaluated as a whole, such that it is clear that treatment has failed and disease is progressing, regardless of the status of the target lesions.

Participant Flow

The study began recruiting in July 2013 and ended May 2017. Subjects were recruited from Los Angeles County + University of Southern California (LAC+USC) Healthcare Network and the Keck Medical Center of USC, Norris Comprehensive Cancer Center in Los Angeles, California.

There were no pre-assignment criteria. All subjects were given the same treatment.

PRIMARY outcome

Timeframe: From study entry to the date of first documented disease progression (assessed every 6 weeks) or death due to any cause, whichever came first, approximately 63 months.

Population: All participants were included in the analysis. Statistical analysis was not performed.

PFS was defined as duration of time from the first dose of study drug to the first documentation of Progressive Disease (PD) by investigator assessment using RECIST 1.1 or death on study due to any cause on or before the data cutoff date, whichever occurred first. PD: \>=20% increase (\>=5 mm absolute increase) in the sum of target lesion measurements, compared to the smallest sum on study (including baseline), or unequivocal progression of non-target lesions, evaluated as a whole, such that it is clear that treatment has failed and disease is progressing, regardless of the status of the target lesions.

Progression Free Survival (PFS)
13.7 months
Interval 2.6 to 16.6

SECONDARY outcome

Timeframe: From study entry until disease progression/recurrence (maximum duration: 351 weeks)

Population: All patients were included in the analysis. Statistical analysis was not performed.

Overall response rate (ORR) is complete response (CR) + partial response (PR) recorded from study entry until disease progression based on RECIST v1.1 criteria. 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

Timeframe: From study entry until the date of the first documented disease progression of date of death whichever came first, assessed for approximately 351 weeks

Population: All patients were included in the analysis. Statistical analysis was not performed.

Participants with a best response of CR, PR, or stable disease (SD) sustained for ≥24 weeks, as assessed using RECIST v1.1. CR: Disappearance of all non-nodal target and non-target lesions, including target and non-target lymph nodes reduction to \<10 mm in short axis. PR: \>=30% decrease in sum of diameters of target lesions, compared to the sum at baseline. SD: Neither PR nor progression of disease (PD) criteria met. SD follow PR only when sum increases by less than 20% from the nadir, but previously seen 30% decrease from baseline no longer hold. PD: \>=20% increase (\>=5 mm absolute increase) in the sum of target lesion measurements, compared to the smallest sum on study (including baseline), or unequivocal progression of non-target lesions, evaluated as a whole, such that it is clear that treatment has failed and disease is progressing, regardless of the status of the target lesions.
