Secondary outcomes (4)
  1. Progression-Free Survival (PFS) Based on Investigator Assessment

    Median time (50 percent [%]) from the first dose of study treatment to the first documentation of objective tumor progression or to death due to any cause, whichever occurs first; based on Investigator assessment. PFS calculated as (Weeks) = (first event date minus first dose date plus 1) divided by 7.

    Measured: First dose of study treatment until progressive disease

  2. Number of Subjects With Objective Response of Complete Response or Partial Response Based on Investigator Assessment

    Number of subjects with objective response based on Investigator assessment of confirmed complete response (CR) or confirmed partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST). Confirmed responses are those that persist on repeat imaging study at least 4 weeks after initial documentation of response.

    Measured: First dose of study treatment until at least 4 weeks after confirmed response or partial response

  3. Number of Subjects With Clinical Benefit of Complete Response, Partial Response, or Stable Disease Based on Investigator Assessment

    Number of subjects with clinical benefit based on Investigator assessment of confirmed complete response (CR), partial response (PR), or stable disease (SD) according to RECIST for at least 24 weeks on study.

    Measured: First dose of study treatment until at least 24 weeks on study

  4. Duration of Tumor Response Based on Investigator Assessment

    Median duration (50%) of tumor response based on Investigator assessment for a subgroup of subjects with objective disease response: who have not progressed or died due to any cause; with a response and subsequent progression or death due to any cause for duration of response (DR). DR defined as time from start of first documented objective tumor response (CR or PR) to first documented objective tumor progression or death due to any cause, whichever occurs first. DR calculated as (Weeks) = (the end date for DR minus first subsequent confirmed CR or PR plus 1) divided by 7.

    Measured: Start of first confirmed CR or PR to first confirmed progression or death

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Sunitinib (Sutent) and Taxotere in people with Breast Neoplasms, run by Pfizer at 3 sites in 3 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 2 inclusion and 3 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 23 Dec 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Belgium, Italy, Sweden. 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 23 Dec 2009). 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?

Time to Reach Maximum Plasma Concentration (Tmax): Sunitinib (SU011248), Sunitinib Metabolite (SU012662), and Total Drug PK Parameters (time frame: 1, 2, 4, 6, 8, 12, 24 hours postdose). The study lists 12 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 23 Dec 2009.
