What is being measured

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

  1. Area Under the Plasma Concentration-time Curve From Time 0 Extrapolated to Infinite Time (AUCinf) of PF-06835919

    AUCinf was defined as area under the plasma concentration time curve from time 0 extrapolated to infinite time.

    Measured: Predose, 0.5, 1, 2, 4, 6, 8, 10, 12, 24, 36, 48 ,72, 96 ,120 hours post dose on Day 1.

  2. Maximum Plasma Concentration (Cmax) of PF-06835919

    Cmax was defined as maximum plasma concentration of PF-06835919 and observed directly from data.

    Measured: Predose, 0.5, 1, 2, 4, 6, 8, 10, 12, 24, 36, 48 ,72, 96 ,120 hours post dose on Day 1.

  3. Unbound Area Under The Plasma Concentration-Time Curve From Time 0 Extrapolated To Infinite Time (AUCinf,u) of PF-06835919

    AUCinf,u was defined as unbound area under the plasma concentration time curve from time 0 extrapolated to infinite time.

    Measured: Predose, 0.5, 1, 2, 4, 6, 8, 10, 12, 24, 36, 48 ,72, 96 ,120 hours post dose on Day 1.

  4. Unbound Maximum Plasma Concentration (Cmax,u) of PF-06835919

    Cmax,u was defined as unbound maximum plasma concentration.

    Measured: Predose, 0.5, 1, 2, 4, 6, 8, 10, 12, 24, 36, 48 ,72, 96 ,120 hours post dose on Day 1.

  5. Fraction of Drug Unbound (fu) of PF-06835919

    The fraction of PF-06835919 unbound in plasma (fu) was determined at approximately the expected Tmax in each participant.

    Measured: Predose, 0.5, 1, 2, 4, 6, 8, 10, 12, 24, 36, 48 ,72, 96 ,120 hours post dose on Day 1.

Secondary outcomes (3)
  1. Number of Participants Reporting Treatment-emergent Adverse Events (AEs)

    An AE was any untoward medical occurrence in a participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An serious adverse event (SAE) was defined as an AE: 1. resulting in death, 2. was life-threatening, 3. required inpatient hospitalization or prolongation of existing hospitalization, 4. resulted in persistent disability, 5. was a congenital anomaly/birth defect, or considered to be an important medical event. Treatment-related AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. Treatment-emergent AE (TEAE) was defined as an AE with onset date occurring during the on-treatment period. AEs included all SAEs and non-SAEs.

    Measured: Baseline (Day 1) up to follow-up (Day 31)

  2. Number of Participants With Clinically Significant Change (Chg) From Baseline in Laboratory Tests

    To determine if there were any clinically significant laboratory abnormalities, hematology (hemoglobin, hematocrit, erythrocytes, mean corpuscular hemoglobin, mean corpuscular volume, platelet count, lymphocytes, neutrophils, activated partial thromboplastin time, prothrombin time, prothrombin intl. normalized ratio), clinical chemistry (bilirubin, direct and indirect bilirubin, gamma glutamyl transferase, albumin, urea nitrogen, glucose) and urinalysis (glucose, protein, hemoglobin, urobilinogen, nitrite) tests were assessed. Each parameter was evaluated against commonly used and widely accepted criteria.

    Measured: Baseline (Day 1) up to Day 6

  3. Number of Participants With Clinically Significant Change From Baseline in 12-Lead Electrocardiograms (ECGs)

    ECG endpoints (PR interval, QRS interval, QT interval and QTcF) meeting the criteria of potential clinical concern were summarized by treatment using categories as defined: 1. PR max. ≥300ms, %Chg ≥25/50%; 3. QRS max. ≥140ms,%Chg ≥50%; 3.maximum post-dose QTcF 450 - ≤480msec, 480 - ≤500msec and >500msec, 30<Chg≤60 and Chg>60.

    Measured: Baseline (Day 1) up to Day 6

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PF-06835919 25 mg in people with Hepatic Impairment and Healthy Participants, 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 4 inclusion and 13 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 16 Feb 2024. 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, Czechia, Slovakia. 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 16 Feb 2024). 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?

Area Under the Plasma Concentration-time Curve From Time 0 Extrapolated to Infinite Time (AUCinf) of PF-06835919 (time frame: Predose, 0.5, 1, 2, 4, 6, 8, 10, 12, 24, 36, 48 ,72, 96 ,120 hours post dose on Day 1.). 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 16 Feb 2024.
