Study start date: July 1, 2003Actual date on which the first participant was enrolled.

This 2 arm study compared the efficacy and safety of label dose of capecitabine (Xeloda®) to that of a lower dose of Xeloda® plus docetaxel (Taxotere®) in patients with locally advanced or metastatic breast cancer after failure of chemotherapy with an anthracycline. Patients were randomized to receive either 1250 mg/m\^2 or 825 mg/m\^2 orally twice a day (po bid) on days 1-14 of each 3 week cycle, in combination with Taxotere® 75 mg/m2 intravenous (iv) on day 1 of each 3 week cycle. The anticipated time on study treatment was until disease progression and the target sample size was 440 individuals.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
470 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

How participants are assigned to different groups/arms
In this clinical study, participants are placed into groups randomly, like flipping a coin. This ensures that the study is fair and unbiased, making the results more reliable. By assigning participants by chance, researchers can better compare treatments without external influences.

Other Ways to Assign Participants
Non-randomized allocation: Participants are assigned based on specific factors, such as their medical condition or a doctor's decision.
None (Single-arm trial): If the study has only one group, all participants receive the same treatment, and no allocation is needed.

How treatments are given to participants
Participants are divided into different groups, each receiving a specific treatment at the same time. This helps researchers compare how well different treatments work against each other.

Other Ways to Assign Treatments
Single-group assignment: Everyone gets the same treatment.
Cross-over assignment: Participants switch between treatments during the study.
Factorial assignment: Participants receive different combinations of treatments.
Sequential assignment: Participants receive treatments one after another in a specific order, possibly based on individual responses.
Other assignment: Treatment assignment does not follow a standard or predefined design.

How the effectiveness of the treatment is controlled
In a non placebo-controlled study, no participants receive an inert substance (placebo) to compare outcomes. Instead, all participants receive either the experimental treatment or an alternative treatment (often the Standard of Care). This method allows researchers to compare the effects of the experimental treatment with those of a different active intervention, rather than a placebo.

Other Options
Placebo-Controlled: A placebo is used to compare the effects of the experimental treatment with those of an inert substance, isolating the true treatment effect.

How the interventions assigned to participants is kept confidential
Everyone involved in the study knows which treatment is being given. This is typically used when it's not possible or necessary to hide the treatment details from participants or researchers.

Other Ways to Mask Information
Single-blind: Participants do not know which treatment they are receiving, but researchers do.
Double-blind: Neither participants nor researchers know which treatment is given.
Triple-blind: Participants, researchers, and outcome assessors do not know which treatment is given.
Quadruple-blind: Participants, researchers, outcome assessors, and care providers all do not know which treatment is given.

2 intervention groups 

are designated in this study

This study does not include a placebo group 

Treatment Groups
Group I
Experimental
1250 mg/m\^2 capecitabine (Xeloda®) orally twice a day on days 1 to 14 of each 3 week cycle, in combination with docetaxel (Taxotere®) 75 mg/m\^2 intravenous on day 1 of each 3 week cycle.

825 mg/m\^2 or 1250 mg/m2 orally twice a day on days 1 to 14 of each 3 week cycle.

75 mg/m\^2 intravenous on day 1 of each 3 week cycle
Group II

825 mg/m\^2 or 1250 mg/m2 orally twice a day on days 1 to 14 of each 3 week cycle.

75 mg/m\^2 intravenous on day 1 of each 3 week cycle
Study Objectives
Primary Objectives

Progression Free Survival was defined as the time from the date of randomization to the day of documented disease progression or death due to any cause.
Secondary Objectives

According to Response Evaluation Criteria in Solid Tumors (RECIST) criteria: CR is defined as the disappearance of all target lesions and PR is defined as at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the nadir sum LD.

For patients with Best Overall Response being Complete Response (CR) or Partial Response (PR), time to response was measured as the time from randomization to the first time when the measurement criteria for CR or PR were met. The percentage of participants with overall response within the given time ranges in each of the categories: Weeks 1-6, 7-12, 13-18, 19-24, 25-30, 31-36, and 43-48 are reported.

Duration of overall response was measured from the time that measurement criteria were first met for Complete Response or Partial Response until the first date that progressive disease or death was documented.

The time to treatment failure was the time from the date of randomization to the first occurrence of any of the following events: * adverse events * insufficient therapeutic response (disease progression) * death * failure to return * refusing treatment/being unwilling to cooperate * withdrawing consent.

Overall Survival was measured as the time from the date of randomization to the date of death.

An adverse event was considered any unfavorable and unintended sign, symptom, or disease associated with the use of the study drug, whether or not considered related to the study drug. Preexisting conditions that worsened during the study were reported as adverse events. A serious adverse event is any experience that suggests a significant hazard, contraindication, side effect or precaution that: results in death, is Life-Threatening, required in-patient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect or is medically significant. Additional information about Adverse Events can be found in the Adverse Event Section.
