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

The purpose of this clinical research study is to learn if BMS-247550 added to the approved therapy of capecitabine is better than capecitabine alone in shrinking or slowing the growth of the cancer in women with metastatic breast cancer who are resistant to taxane and received anthracycline chemotherapy. The safety of this treatment will also be studied.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
752 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.

Criteria

* Patients must have received either 2 or 3 prior chemotherapy regimens including adjuvant or neoadjuvant therapy. * Prior treatment must have included both an anthracycline (i.e., doxorubicin or epirubicin) and a taxane (i.e., paclitaxel or docetaxel). * Patients must have received a minimum cumulative dose of anthracycline or must be resistant to an anthracycline. * Patients must be resistant to taxane therapy. * Patients may not have any history of brain and/or leptomeningeal metastases. * Patients may not have CTC Grade 2 or greater neuropathy (motor or sensory). * Patients may have not have had prior treatment with an epothilone and/or capecitabine (i.e., Xeloda)

Treatment Groups
Study Objectives
2 intervention groups 

are designated in this study

This study does not include a placebo group 

Treatment Groups
Group I
Experimental

Ixabepilone - Intravenous Solution, IV 40mg/m², Day 1 every 21 days, Until progression/unacceptable toxicity Capecitabine (Active Comparator) - Tablet, Oral, 2000 mg/m², Bid Days 1-14 every 21 days, Until progression/unacceptable toxicity
Group II
Active Comparator

Tablet, Oral, 2500 mg/m², Bid Days 1-14 every 21 days, Until progression/unacceptable toxicity
Study Objectives
Primary Objectives

PFS defined as the time in months from randomization to date of progression. Patients who died without a reported prior progression were considered to have progressed on date of death; those who didn't progress or die were censored on date of last tumor assessment. Median PFS time with 95% CI estimated using the Kaplan Meier product limit method.
Secondary Objectives

Participants with best response of "Complete" or "Partial" according to Response Evaluation Criteria in Solid Tumors (RECIST) a 4-item scale wherein complete response=disappearance of all target lesions and partial response=30% decrease in the sum of the longest diameter of target lesions

Computed for all patients with a best response of "Partial" or "Complete" per RECIST (a 4-item scale as described in previous outcome measure), calculated from the time when these criteria were first met until the first date of documented progression or death.

Time to response was summarized using descriptive statistics and was defined as the time from first dose of study treatment until measurement criteria were first met for Partial Response or Complete Response.

OS was defined as the time from randomization to death. Participants who did not die at the time of the analysis were censored at the latest follow-up date. Median OS with 95% CI was estimated using the Kaplan Meier product limit method.

Laboratory values, adverse events, and other symptoms were graded using the National Cancer Institute's Common Terminology Criteria for Adverse Events (CTC) Version 3.0

Quality of life, as measured by the FBSI, an 8-item, participant-reported instrument to measure symptoms. Each item has 5 possible responses ranging from 0 (not at all) to 4 (very much). The scoring was conducted according to the Functional Assessment of Chronic Illness Therapy manual, Version 4; higher scores reflect fewer symptoms.
