What is being measured

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

  1. Number of Subjects With Treatment Emergent Treatment-Related Adverse Events (AEs) or other safety concerns

    Assessment by adverse event monitoring, 12 lead ECGs, telemetry, vital signs and clinical safety laboratory measurements.

    Treatment-related AE was any untoward medical occurrence attributed to study drug in a subject who received study drug. Serious adverse event (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. Treatment-emergent are events between first dose of study drug and up to 28 days after last dose that were absent before treatment or that worsened relative to pretreatment state. Relatedness to Drug was assessed by the investigator (Yes/No). Subjects with multiple occurrences of an AE within a category were counted once within the category.

    Measured: Baseline (Day 0) up to 28 days after last dose of study medication

  2. Number of Participants with Draize-like scoring and clinical observation

    Modified Draize-like scoring and clinical observation. Severity estimated by clinical signs and scoring; ranged 0-4: 0= No reaction visible, 1= Trace reaction - barely perceptible pinkness, 2= Mild reaction - readily visible pinkness, 3= Moderate reaction - definite redness, 4= Strong to severe reaction - very intense redness.

    Measured: Baseline (Day 1) up to Day 42+3

  3. Number of Participants With Clinical Laboratory Abnormalities

    Following parameters were analyzed for laboratory examination: hematology (hemoglobin, hematocrit, red blood cell count, platelet count, white blood cell count, total neutrophils, eosinophils, monocytes, basophils, lymphocytes); liver function (aspartate aminotransferase, alanine aminotransferase, total bilirubin, lactate dehydrogenase, alkaline phosphatase, albumin, total protein); renal function (blood urea nitrogen, creatinine, uric acid); electrolytes (sodium, potassium, chloride, calcium, phosphate, bicarbonate); clinical chemistry (glucose, creatine kinase); immunology (CRP); urinalysis (dipstick [urine specific gravity, decimal logarithm of reciprocal of hydrogen ion activity {pH} of urine, glucose, protein, blood, ketones, bilirubin], microscopy [urine RBC, WBC, urate crystals, calcium, oxalate, miscellaneous [urine mucus and leucocytes]).

    Measured: Baseline (Day 0) up to 28 days after last dose

  4. Number of Participants With Abnormal Electrocardiogram (ECG)

    Criteria for potential clinical concern in ECG parameters: Maximum QTcF interval (Fridericia's Correction) in range of 450 to less than 480 msec, maximum QTc interval increase from baseline in range of 30 to less than 60 msec and >=60 msec.

    Measured: Baseline (Day 0) up to 28 days after last dose

  5. Number of Participants With Categorical Vital Signs Data

    Number of participants with maximum increase from Baseline in sitting SBP and DBP of greater than or equal to 30 mmHg was reported.

    Measured: Baseline (Day 0) up to 28 days after last dose

Secondary outcomes (8)
  1. Maximum Observed Plasma Concentration (Cmax) for PF-06423264

    Maximum Observed Plasma Concentration (Cmax)

    Measured: 0, 0.5, 1, 2, 4, 5, 6, 8, 12, 24 hours post dose on Day 1 and 0, 0.5, 1, 2, 4, 5, 6, 8, 12, 24, 36, and 48 hours post dose on Day 14

  2. Time to Reach Maximum Observed Concentration for PF-06423264

    Time to Reach Maximum Observed Plasma Concentration (Tmax)

    Measured: 0, 0.5, 1, 2, 4, 5, 6, 8, 12, 24 hours post dose on Day 1 and 0, 0.5, 1, 2, 4, 5, 6, 8, 12, 24, 36, and 48 hours post dose on Day 14

  3. Area Under the Curve From Time Zero to End of Dosing Interval (AUCtau) for PF-06423264

    Area under the concentration curve from time 0 to end of dosing interval (AUCtau), where dosing interval was 12 hours.

    Measured: 0, 0.5, 1, 2, 4, 5, 6, 8, 12, 24 hours post dose on Day 1 and 0, 0.5, 1, 2, 4, 5, 6, 8, 12, 24, 36, and 48 hours post dose on Day 14

  4. Plasma Decay Half-Life (t1/2) for PF-06423264

    Plasma Decay Half-Life (t1/2)

    Measured: 0, 0.5, 1, 2, 4, 5, 6, 8, 12, 24 hours post dose on Day 1 and 0, 0.5, 1, 2, 4, 5, 6, 8, 12, 24, 36, and 48 hours post dose on Day 14

  5. Apparent Volume of Distribution (Vz/F) for PF-06423264

    Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed.

    Measured: 0, 0.5, 1, 2, 4, 5, 6, 8, 12, 24 hours post dose on Day 1 and 0, 0.5, 1, 2, 4, 5, 6, 8, 12, 24, 36, and 48 hours post dose on Day 14

  6. Apparent Total Body Clearance (CL/F) for

    Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after apparent total body clearance is influenced by the fraction of the dose absorbed. Clearance was estimated from population pharmacokinetic (PK) modeling. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

    Measured: 0, 0.5, 1, 2, 4, 5, 6, 8, 12, 24 hours post dose on Day 1 and 0, 0.5, 1, 2, 4, 5, 6, 8, 12, 24, 36, and 48 hours post dose on Day 14

  7. Observed Accumulation Ratio (Rac) for PF-06423264

    Rac was calculated as, area under the curve from time zero to end of dosing interval on Day Y (AUCtau) divided by area under the curve from time zero to end of dosing interval on Day X(AUCtau).

    Measured: 0, 0.5, 1, 2, 4, 5, 6, 8, 12, 24 hours post dose on Day 1 and 0, 0.5, 1, 2, 4, 5, 6, 8, 12, 24, 36, and 48 hours post dose on Day 14

  8. change from baseline in sebum lipid components and sebum excretion

    change from baseline in sebum lipid components and sebum excretion as assessed with Sebutape strips and Sebumeter measurements on the forehead of subjects with oily skin

    Measured: Baseline (Day 0) up to 16 days after last dose of study medication

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PF-06423264 in people with Normal Healthy, run by Pfizer at 1 site in Belgium.

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: stopped early, as of the sponsor's last update on 21 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Belgium. 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. Some participants in this study may receive a placebo. 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?

The study was stopped early (reason given: Preliminary analysis of accrued data failed to indicate any meaningful pharmacodynamic response.). Results are not available in the source record.

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 Subjects With Treatment Emergent Treatment-Related Adverse Events (AEs) or other safety concerns (time frame: Baseline (Day 0) up to 28 days after last dose of study medication). The study lists 5 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 21 Jun 2017.
