What is being measured

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

  1. Progression-Free Survival (PFS)

    PFS was calculated from the time of randomization to either progression of disease, death, or treatment discontinuation because of unsatisfactory therapy results (such as global deterioration of health status). Disease progression was defined as 1 or more of the following: radiographic progression (20 percent [%] increase in measurable lesions, appearance of new lesions or unequivocal progression of evaluable lesions as defined by Response Evaluation Criteria in Solid Tumors [RECIST]); occurrence of new pleural/pericardial effusions or ascites confirmed by positive cytology; persistent hypercalcemia requiring more than 2 IV treatments with bisphosphonates; intervention for any cancer-related events (radiations, surgery) or new symptoms related to tumor growth requiring participant discontinuation; development of brain metastasis; or death for any cause. Median PFS was estimated from the Kaplan-Meier curve. 95% confidence interval (CI) is based on the Brookmeyer and Crowley method.

    Measured: Baseline, Day 1 of Cycles 2 and 4 and then Day 1 of every 3rd cycle starting at Cycle 7 up to 60 months

  2. PFS in Participants With Hemoglobin A1c (HbA1c) Less Than (<) 5.7% at Baseline

    PFS was calculated from the time of randomization to either progression of disease, death, or treatment discontinuation because of unsatisfactory therapy results (such as global deterioration of health status). Disease progression was defined as 1 or more of the following: radiographic progression (20% increase in measurable lesions, appearance of new lesions or unequivocal progression of evaluable lesions as defined by RECIST); occurrence of new pleural/pericardial effusions or ascites confirmed by positive cytology; persistent hypercalcemia requiring more than 2 IV treatments with bisphosphonates; intervention for any cancer-related events (radiations, surgery) or new symptoms related to tumor growth requiring participant discontinuation; development of brain metastasis; or death for any cause. Median PFS was estimated from the Kaplan-Meier curve. 95% CI is based on the Brookmeyer and Crowley method.

    Measured: Baseline, Day 1 of Cycles 2 and 4 and then Day 1 of every 3rd cycle starting at Cycle 7 up to 60 months

Secondary outcomes (9)
  1. Percentage of Participants Achieving Complete Response (CR), Partial Response (PR), or Stable Disease (SD) Maintained for at Least 6 Months

    Objective responses were defined using RECIST as CR: disappearance of all target and nontarget lesions. PR: at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as a reference the baseline sum LD. Nontarget lesions may persist provided there is no unequivocal progression in these lesions. SD: measurements demonstrating neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify as progressive disease (PD) during the first 6 weeks after the start of treatment taking as reference the smallest sum LD since the treatment started. During this time, nontarget lesions may persist provided there is no unequivocal progression in these lesions.

    Measured: Baseline, Day 1 of Cycles 2 and 4 and then Day 1 of every 3rd cycle starting at Cycle 7 up to 60 months

  2. Maximum Plasma Concentration of CP-751,871

    Measured: Predose on Day 1 at Cycles 1, 2, 4, and 5 and 150 days post last dose of CP-751,871 and for salvage therapy, at Day 1 and 150 days post last dose of CP-751,871

  3. Minimum Plasma Concentration of CP-751,871

    Measured: Predose on Day 1 at Cycles 1, 2, 4, and 5 and 150 days post last dose of CP-751,871 and for salvage therapy, at Day 1 and 150 days post last dose of CP-751,871

  4. Area Under the Concentration Time Curve From Time 0 to the Last Time Point With Quantifiable Concentration

    Measured: Predose on Day 1 at Cycles 1, 2, 4, and 5 and 150 days post last dose of CP-751,871 and for salvage therapy, at Day 1 and 150 days post last dose of CP-751,871

  5. Number of Participants With Negative Human Anti-Human Antibodies (HAHAs)

    Negative human anti-human antibodies were defined as <6.64

    Measured: Predose on Day 1 of Cycle 1 and at 150 days post last CP-751,871 infusion

  6. Percentage of Participants With Circulating Tumor Cells Expressing Insulin-Like Growth Factor 1 Receptor (IGF-IR)

    Measured: Predose on Day 1 of Cycle 1

  7. Percentage of Participants With Serum Markers Relevant to the IGF-1R Pathway

    Measured: Predose on Day 1 of Cycles 1 and 4 and at end of treatment prior to beginning salvage therapy

  8. European Organization for the Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire 30 (QLQ-C30) Scores

    EORTC QLQ-C30: included functional scales (physical, role, cognitive, emotional, and social), global health status, symptom scales (fatigue, pain, nausea/vomiting) and single items (dyspnoea, appetite loss, insomnia, constipation/diarrhea and financial difficulties). Most questions used 4 point scale (1 'Not at all' to 4 'Very much'; 2 questions used 7-point scale (1 'very poor' to 7 'Excellent'). Scores averaged, transformed to 0-100 scale; higher score equals (=) better level of functioning or greater degree of symptoms.

    Measured: Predose on Day 1 of each cycle, at the end of treatment and at follow-up, up to 60 months

  9. EORTC QLQ Breast Cancer Module (BR23) Scores

    EORTC-QLQ-BR23: included functional scales (body image, sexual functioning, sexual enjoyment, and future perspective) and single item symptoms scales (systemic therapy side effects, breast symptoms, arm symptoms, and upset by hair loss). Questions used 4-point Likert scale (1 ‘Not at All’ to 4 ‘Very Much’). Scores averaged and transformed to 0-100 scale. High score for functional scale=high/healthy level of functioning. High score for single item=high level of symptomatology/problems. Change from baseline=Cycle/Day score minus baseline score.

    Measured: Predose on Day 1, at end of treatment, and at Follow-up, up to 60 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing CP-751,871, exemestane and Fulvestrant in people with Breast Neoplasms, run by Pfizer at 62 sites in 9 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 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: stopped early, as of the sponsor's last update on 28 Oct 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 62 sites in United States, Argentina, Brazil, Belgium, Italy and 4 more countries. 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 28 Jul 2015). 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?

Progression-Free Survival (PFS) (time frame: Baseline, Day 1 of Cycles 2 and 4 and then Day 1 of every 3rd cycle starting at Cycle 7 up to 60 months). 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 28 Oct 2015.
