July 10, 2014 updated by: LiNanlin,Ph.D, Chief Physician,Clinical Professor, Xijing Hospital

Maintenance Versus Observation With 6 Cycles of Gemcitabine Plus Taxol Sequential Gemcitabine Single Agent in Patients With Metastatic Breast Cancer

The primary purpose of our study is to evaluate whether gemcitabine as a single agent is superior to observation in improving progression-free survival (PFS) in patients with metastatic breast cancer (MBC) who achieved disease control with an initial six cycles of PG as their first-line treatment

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

Patients with MBC exhibited disease control (complete response + partial response + stable disease) with first-line PG and were randomly assigned to maintenance chemotherapy or observation.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Gemcitabine, Experimental
Gemcitabine 1250 mg/m2, IV on day 1 of 21 day cycle,with a follow up for every 12 weeks until disease progression or the date of first documented death from any cause
Observational
Observation for every 12 weeks until disease progression or the date of first documented death from any cause

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
PFS
Time Frame: From randomization to disease progression
From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 3 years
From randomization to disease progression
PFS(progression free survival)
Time Frame: time from the date of randomization until the date of disease progression，assessed up to 3 years
time from the date of randomization until the date of disease progression，assessed up to 3 years
PFS(progression free survival)
Time Frame: the time from the date of randomization until the date of disease progression,assessed up to 3 years
PFS was defined as the time from the date of randomization until the date of disease progression at any site including distant metastasis or second primary tumors or death,assessed up to 3 years
the time from the date of randomization until the date of disease progression,assessed up to 3 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
OS(overall survival)
Time Frame: the time from date of randomization until the date of first documented death from any cause,assessed up to 3 years
the time from date of randomization until the date of first documented death from any cause,assessed up to 3 years
the time from date of randomization until the date of first documented death from any cause,assessed up to 3 years

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
QoL(quality of life)
Time Frame: the time from enrollment to disease progression or the date of first documented death,assessed up to 3 years
the time from enrollment to disease progression or the date of first documented death,whichever comes first,to observe the quality of life in participants,assessed up to 3 years
the time from enrollment to disease progression or the date of first documented death,assessed up to 3 years

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.

Study Completion (Anticipated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
