What is being measured

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

  1. Number of Participants With Dose-limiting Toxicities (DLTs) in Cycle 1

    Any DLT event in Cycle 1: Grade 4 neutropenia lasting more than (>)7 days; febrile neutropenia (Grade more than or equal to [>=] 3 and body temperature >=38.5 degrees Celsius); Grade >=3 neutropenic infection; Grade >=3 thrombocytopenia with bleeding; Grade 4 thrombocytopenia without bleeding; Grade >=3 toxicities (except those that had not been maximally treated); Grade 3 prolongation of time from electrocardiogram (ECG) Q wave to the end of the T wave corresponding to electrical systole (QT) corrected for heart rate (QTc) which persisted after correction of reversible causes; delay of 2 weeks in receiving next scheduled cycle due to persisting treatment-related toxicities; and failure to deliver at least 80% of planned dose during first cycle due to treatment-related toxicities.

    Measured: Cycle 1 Days 1-21

  2. Progression-free Survival (PFS) at 6 Months - Expansion Cohort

    The period from study entry until disease progression, death or date of last contact. Assessment of response was made using Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.

    Measured: Baseline till 6 months post-dose

Secondary outcomes (19)
  1. Number of Participants With All Causality and Treatment-related Treatment-emergent Adverse Events (TEAEs), Serious Adverse Events (SAEs), and Withdrawals Due to TEAEs

    An adverse event (AE) was any untoward medical occurrence attributed to study drug in a participant who received study drug. Treatment-emergent AEs (TEAEs) are defined as newly occurring AEs or those worsening after first dose. AEs comprised both SAEs and non-SAEs. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Causality assessment was made by the investigator. Grading was per the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Event (CTCAE) version 3.0: Grade 1=mild, Grade 2=moderate, Grade 3=severe, Grade 4=life-threatening, Grade 5=death related to AE.

    Measured: Baseline up to 28-35 days after treatment discontinuation (up to Day 280)

  2. Number of Participants With Laboratory Abnormalities

    Number of participants with laboratory test abnormalities without regard to baseline abnormality. Laboratory test parameters included hematology, coagulation, liver function, renal function, electrolytes, clinical chemistry, and urinalysis (dipstick).

    Measured: Baseline up to 28-35 days after treatment discontinuation (up to Day 280)

  3. Percentage of Participants With Objective Response (OR)

    OR was based on assessment of confirmed complete response (CR) or confirmed partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. CR was defined as complete disappearance of all target lesions and non-target disease, with the exception of nodal disease. All nodes, both target and non-target, must decrease to normal (short axis less than [<] 10 millimeters [mm]). No new lesions. PR was defined as more than or equal to (>=) 30% decrease under baseline of the sum of diameters of all target lesions. The short axis was used in the sum for target nodes, while the longest diameter was used in the sum for all other target lesions. No unequivocal progression of non-target disease. No new lesions.

    Measured: Baseline, every 6 weeks from Cycle 2 onwards up to 26 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PF-03084014 and Docetaxel in people with Breast Cancer Metastatic, run by Pfizer at 16 sites in 4 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 1 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 15 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 16 sites in United States, Belgium, Spain, 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 15 Mar 2019). 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 Dose-limiting Toxicities (DLTs) in Cycle 1 (time frame: Cycle 1 Days 1-21). 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 15 Mar 2019.
