What is being measured

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

  1. Number of Participants With Clinical Benefit (CBR) and Number of Participants With CBR Having a Disease Free Interval (DFI) Greater Than 2 Years - Evaluable Population

    CBR=participants with complete response (CR) + participants with partial response (PR) + participants with stable disease (SD) for a length of time greater than, equal to 6 months. CR= Disappearance of all target lesions. No new lesions. PR= At least a 30% decrease in the sum of the longest diameter (LD) of target lesions taking as reference the baseline sum LD. SD= Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD) taking as reference the smallest sum LD since the treatment started. Physical examination,radiological assessment, and bone scans (if applicable) were used to assess outcome.

    Measured: First dose of study drug to last dose plus 7 days, up to study completion (approximately 6 years)

Secondary outcomes (6)
  1. Number of Participants With Complete Response, Partial Response, Stable Disease, and Disease Progression

    CR= Disappearance of all target lesions. No new lesions. PR= At least a 30% decrease in the sum of the longest diameter (LD) of target lesions taking as reference the baseline sum LD. SD= Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD) taking as reference the smallest sum LD since the treatment started. Progression (PD): At least a 20% increase in the sum of LD of target lesions taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions.

    Measured: First dose of study drug to last dose plus 7 days, up to study completion (approximately 6 years)

  2. Median Progression Free Survival (PFS) - Intent to Treat (ITT) Population

    PFS was measured in months. Progression=At least a 20% increase in the sum of LD of target lesions taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. Study initiated 2008 and completed 2014.

    Measured: Day 1 to Study Completion (approximately 6 years)

  3. Percentage of Participants Best Overall Response After Change From Letrozole to Letrozole Plus Dasatinib

    Participants in single-agent letrozole treatment arm who developed progressive disease, could continue letrozole, and add dasatinib to their treatment regimen. CBR=participants with CR + participants with partial response (PR) + participants with SD for a length of time ≥6 months divided by the total number of participants (%). CR= Disappearance of all target lesions. No new lesions. PR= At least a 30% decrease in the sum of the longest diameter (LD) of target lesions taking as reference the baseline sum LD. SD= Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD) taking as reference the smallest sum LD since the treatment started. PD=At least a 20% increase in the sum of LD of target lesions taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions.

    Measured: First dose of study drug to last dose plus 7 days, up to study completion (approximately 6 years)

  4. Percentage of Participants With PFS At 6 Months and At 12 Months - ITT Population

    Progression=At least a 20% increase in the sum of LD of target lesions taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. ITT population: from time of first enrollment to first PD for all ITT participants.

    Measured: At 6 months and at 12 months

  5. Median Time to Treatment Failure (TTF) - ITT Population

    Time to TTF was measured in months. The number of participants with events (PD or off treatment due to any reason) was evaluated. The first PD was defined as the event for cross over participants in the single- agent letrozole treatment arm to add dasatinib to their regimen.

    Measured: First dose of study drug to last dose plus 7 days, up to study completion (approximately 6 years)

  6. Number of Participants With Adverse Events (AEs) Leading to Discontinuation, Serious Adverse Events (SAEs), and Deaths

    AE=any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that may not have a causal relationship with treatment. SAE=a medical event that at any dose results in death, persistent or significant disability/incapacity, or drug dependency/abuse; is life-threatening, an important medical event, or a congenital anomaly/birth defect; or requires or prolongs hospitalization.

    Measured: First dose of study drug to last dose plus 30 days, up to study completion (approximately 6 years)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Dasatinib and Letrozole in people with Metastatic Breast Cancer, run by Bristol-Myers Squibb at 27 sites in United States.

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 8 inclusion and 5 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 13 Jun 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 27 sites in United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 11 May 2016). 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 Clinical Benefit (CBR) and Number of Participants With CBR Having a Disease Free Interval (DFI) Greater Than 2 Years - Evaluable Population (time frame: First dose of study drug to last dose plus 7 days, up to study completion (approximately 6 years)). 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 13 Jun 2016.
