What is being measured

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

  1. Number of Participants With Treatment Emergent Adverse Events (TEAEs)

    An adverse event (AE) was any untoward medical occurrence in a patient or clinical study subject, temporally associated with the use of study intervention, whether or not considered related to the study intervention. A serious AE (SAE) was defined as any untoward medical occurrence that, at any dose: resulted in death; was life-threatening; required inpatient hospitalization or prolongation of existing hospitalization; resulted in persistent disability/incapacity; was a congenital anomaly/birth defect; or other serious situations such as important medical events. TEAEs were events between first dose of study drug and up to follow-up visit that were absent before treatment or that worsened after treatment. AEs presented below were TEAEs. The investigator was required to use clinical judgment to assess the potential relationship between investigational product and each AE, to define an treatment-related AE.

    Measured: From first dose of study intervention (Day 1) to telephone Follow Up (28-35 days after lase dose of study intervention) (approximately up to 20 weeks)

  2. Number of Participants With Clinical Laboratory Abnormalities (Without Regard to Baseline [BL] Abnormality)

    Safety laboratory assessments included clinical chemistry, hematology, urinalysis, and other tests. Abnormality was determined at the investigator's discretion.

    Measured: From BL to onsite Follow Up visit (up to 9 days after last dose of study intervention) (approximately up to 17 weeks)

  3. Number of Participants With Change From BL in Vital Signs Data Meeting the Pre-defined Categorical Summarization Criteria

    Abnormality in change from BL in vital signs included: standing diastolic blood pressure (BP) increase and decrease from BL of >=20mmHg, standing systolic BP increase and decrease from BL of >=30mmHg, supine diastolic BP increase and decrease from BL of >=20mmHg, supine systolic BP increase and decrease from BL of >=30mmHg.

    Measured: From BL to onsite Follow Up visit (up to 9 days after last dose of study intervention) (approximately up to 17 weeks)

  4. Number of Participants With Change From BL in Electrocardiogram (ECG) Data Meeting the Pre-defined Categorical Summarization Criteria

    ECG assessments inlcuded PR, QT, QTcF intervals and QRS complex. ECG abnormalities in change from BL included: PR interval BL >200msec and max >=25% increase from BL, or BL <=200msec and max >=50% increase from BL, QRS interval percent change from BL >=50%, QTcF change from BL >=30 and <=60msec, or change from BL >60msec.

    Measured: From BL to onsite Follow Up visit (up to 9 days after last dose of study intervention) (approximately up to 17 weeks)

  5. Number of Participants With Clinically-significant Change From BL in Neurological Examination Findings

    The neurological exam consisted of assessment of higher cortical function, the cranial nerves, motor function, deep tendon reflexes, sensory exam, and coordination and gait, to the extent needed to assess the participant for any potential changes in neurological status, as determined by the investigator (or designee).

    Measured: From BL to onsite Follow Up visit (up to 9 days after last dose of study intervention) (approximately up to 17 weeks)

Secondary outcomes (5)
  1. Maximum Observed Concentration (Cmax) of PF-07258669

  2. Area Under the Plasma Concentration-time Profile From Time 0 to the Time of the Last Quantifiable Concentration (AUClast) of PF-07258669

    AUClast is the area under the plasma concentration-time profile from time 0 to the time of the last quantifiable concentration.

    Measured: At 0 (prior to dose), 0.17, 0.5, 1, 1.5, 2, 4, 6, 8, 12, 16, 24, 36, and 48 hours post dose on Day 1 in Periods 1 to 4

  3. Area Under the Plasma Concentration Time Profile From Time 0 Extrapolated to Infinite Time (AUCinf) of PF-07258669

    AUCinf is the area under the plasma concentration time profile from time 0 extrapolated to infinite time.

    Measured: At 0 (prior to dose), 0.17, 0.5, 1, 1.5, 2, 4, 6, 8, 12, 16, 24, 36, and 48 hours post dose on Day 1 in Periods 1 to 4

  4. Time for Cmax (Tmax) of PF-07258669

    Tmax is the time for Cmax.

    Measured: At 0 (prior to dose), 0.17, 0.5, 1, 1.5, 2, 4, 6, 8, 12, 16, 24, 36, and 48 hours post dose on Day 1 in Periods 1 to 4

  5. Terminal Half-life (t1/2) of PF-07258669

    t1/2 is the terminal half-life.

    Measured: At 0 (prior to dose), 0.17, 0.5, 1, 1.5, 2, 4, 6, 8, 12, 16, 24, 36, and 48 hours post dose on Day 1 in Periods 1 to 4

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PF-07258669 in people with Healthy Participants, run by Pfizer at 1 site 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 3 inclusion and 6 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 21 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 1 site 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 21 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?

Number of Participants With Treatment Emergent Adverse Events (TEAEs) (time frame: From first dose of study intervention (Day 1) to telephone Follow Up (28-35 days after lase dose of study intervention) (approximately up to 20 weeks)). 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 Feb 2024.
