What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With a Dose Limiting Toxicity (DLT)

    DLT: any of the following considered related to ixabepilone, epirubicin or combination occurring in Cycle 1: Absolute neutrophil count <500 cells/mm^3 for ≥7 consecutive days or febrile neutropenia of any duration;Grade(Gr)4 thrombocytopenia <25,000 cells/mm^3 or Gr3 w/bleeding requiring platelet transfusion;Any other drug-related Gr3/4 non-hematologic toxicity except Gr3 injection site reaction, fatigue, transient arthralgia/myalgia;Delayed recovery to Gr≤1 or baseline (except for alopecia) from toxicity related to treatment w/ ixabepilone + epirubicin delaying initiation of next cycle ≥3 wks

    Measured: From Baseline to the end of Cycle 1 (Day 21)

  2. Ixabepilone Maximum Tolerated Dose (MTD) and Recommended Phase 2 Dose (R2PD)

    The MTD was the highest dose in which 0/6 or 1/6 participants experienced DLT with at least 2 out of no more than 6 participants experiencing DLT at the next higher dose level. The RP2D was based on the MTD and the assessment of any relevant chronic toxicity. To obtain further confidence in the RP2D, a total maximum of 30 evaluable participants were enrolled at the MTD.

    Measured: Day 21 of Cycle 1

Secondary outcomes (14)
  1. Number of Participants With Death, Adverse Events (AEs), Serious Adverse Events (SAEs), Grade 3/4 AEs, or AEs Leading to Discontinuation

  12. Number Of Participants With A Best Overall Tumor Response of Complete Response, Partial Response, Stable Disease, And Progressive Disease

    Information on all tumor lesions was obtained at baseline by radiologic techniques, or if appropriate by physical examination (e.g. subcutaneous nodules). Measurable tumors were evaluated using Response Evaluation Criteria In Solid Tumors (RECIST) criteria, wherein complete response (CR) = disappearance of all target lesions; partial response (PR) = ≥30% decrease in the sum of the longest diameter of target lesions; progressive disease (PD)= ≥20% increase in the sum of the longest diameter of target lesions, and stable disease (SD) = small changes that do not meet above criteria.

    Measured: From Baseline (up to 2 weeks prior to starting therapy) to the end Cycle 2

  13. Duration of Tumor Response

    Defined as the interval measured from the time that the measurement criteria are first met for CR or PR, whichever occurs first, until the date of documented progressive disease or death. CR= disappearance of all target lesions; PR= ≥30% decrease in the sum of the longest diameter of target lesions.

    Measured: Time (in months) when criteria for CR or PR are met (which ever occurs first) up to date of progressive disease.

  14. Number Of Participants With Tumor Response by Duration of Response Category

    Duration of response was defined as the interval measured from the time that the measurement criteria are first met for CR or PR, whichever occurs first, until the date of documented progressive disease or death; PR= ≥30% decrease in the sum of the longest diameter of target lesions.

    Measured: Time (in months) when criteria for CR or PR are met (which ever occurs first) up to date of progressive disease.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Ixabepilone and Epirubicin in people with Metastatic Breast Cancer, run by R-Pharm at 2 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Mar 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in France, Italy. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 Aug 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With a Dose Limiting Toxicity (DLT) (time frame: From Baseline to the end of Cycle 1 (Day 21)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Mar 2016.
