Area Under the Plasma Concentration-time Profile From Time 0 to 24 Hours (AUC24) for PF-06651600
AUC24 of PF-06651600 pre and post dose.
Measured: Hour 0 (pre-dose) on Days 7, 8 and 9, and hour 0 (pre-dose), 0.5, 1, 2, 3, 4, 6, 8, 12, 14, 24 hours post-dose on Day 10
Maximum Plasma Concentration (Cmax) for PF-06651600

Secondary outcomes (4)

Number of Participants With Treatment Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs) (All Causalities and Treatment-related)
AEs with all causalities were any untoward medical occurrences in a study participant administered a product which did not necessarily had causal relationship with the treatment or usage. An SAE was an AE resulting in any of the following endpoints or deemed significant for any other reason: death; life threatening (immediate risk of death); inpatient hospitalization or prolongation of existing hospitalization; persistent or significant disability/incapacity; 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 are events between first dose of study drug and up to 35 days after last dose that were absent before treatment or that worsened relative to pretreatment state.
Measured: Baseline (Day 0) up to 28 days after last dose of study medication (Day 39)
Number of Participants With Laboratory Abnormalities (Without Regard to Baseline Abnormality)
Laboratory parameters included: hematology (hemoglobin, hematocrit, erythrocytes, leukocytes, neutrophils, prothrombin time, prothrombin intl. normalized ratio), chemistry (bilirubin, direct bilirubin, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, albumin, sodium, potassium, calcium, bicarbonate and glucose), urinalysis (glucose, ketones, protein, hemoglobin, urobilinogen, bilirubin and nitrite). Each parameter was evaluated against commonly used and widely accepted criteria.
Measured: Baseline (Day 0) up to 28 days after last dose of study medication (Day 39)
Number of Participants With Out of Range Vital Signs
Vital signs included supine blood pressure, pulse rate and temperature. The pre-specified out of range criterion for supine diastolic blood pressure was change from baseline equal to or over than (≥) 20 millimeter of mercury (mmHg). Clinical significance of vital signs and out of range criterion were determined at the investigator's discretion.
Measured: Baseline (Day 0) up to 28 days after last dose of study medication (Day 39)
Number of Adverse Events Leading to Discontinuation
Adverse events result in participants discontinuations from the study drug.
Measured: Baseline (Day 0) up to 28 days after last dose of study medication (Day 39)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PF-06651600 30 mg in people with Hepatic Impairment and Healthy Participants, run by Pfizer at 2 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 9 inclusion and 8 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 8 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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 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 8 Apr 2021). 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 Profile From Time 0 to 24 Hours (AUC24) for PF-06651600 (time frame: Hour 0 (pre-dose) on Days 7, 8 and 9, and hour 0 (pre-dose), 0.5, 1, 2, 3, 4, 6, 8, 12, 14, 24 hours post-dose on Day 10). 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?

On the ClinicalTrials.gov record for NCT04016077, which also lists 2 linked publications.

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 8 Apr 2021.
