- Use of prescription or nonprescription drugs and dietary and herbal supplements within 7 days or 5 half-lives (whichever is longer) prior to the first dose of study intervention with the exception of moderate/strong CYP3A inducers or inhibitors which are prohibited within 14 days plus 5 half-lives prior to the first dose of study intervention.
Show all 19Show fewer
- Previous administration with an investigational product (drug or vaccine) within 30 days (or as determined by the local requirement) or 5 half-lives preceding the first dose of study intervention used in this study (whichever is longer). Participation in studies of other investigational products (drug or vaccine) at any time during their participation in this study.
- Previous exposure to PF-07293893 treatment.
- A positive urine drug test.
- Screening supine BP ≥140 mm Hg (systolic) or ≥90 mm Hg (diastolic) for participants <60 years; and ≥150/90 mm/Hg for participants ≥60 years old, following at least 5 minutes of supine rest. If systolic BP is ≥ 140 or 150 mm Hg (based on age) or diastolic ≥90 mm Hg, the BP should be repeated 2 more times and the average of the 3 BP values should be used to determine the participant's eligibility.
- Renal impairment as defined by an estimated glomerular filtration rate (eGFR) <75 mL/min/1.73m². Since participants are 18 years to 65 years, 2021 Screat-based CKD-EPI eGFR is the recommended formula.
- Standard 12-lead ECG that demonstrates clinically relevant abnormalities that may affect participant safety or interpretation of study results (eg, QTcF >450 ms, complete LBBB, signs of an acute or indeterminate- age myocardial infarction, ST-T interval changes suggestive of myocardial ischemia, second- or third- degree AV block, or serious bradyarrhythmias or tachyarrhythmias). If QTcF exceeds 450 ms, or QRS exceeds 120 ms, the ECG should be repeated twice and the average of the 3 QTcF or QRS values used to determine the participant's eligibility. Computer interpreted- ECGs should be overread by a physician experienced in reading ECGs before excluding a participant.
- Participants with ANY of the following abnormalities in clinical laboratory tests at screening, as assessed by the study -specific laboratory and confirmed by a single repeat test, if deemed necessary: ALT, AST, Bili ≥ 1.05 x ULN. participants with a history of Gilbert's syndrome may have direct bilirubin measured and would be eligible for this study provided the direct bilirubin level is ≤ ULN.
- CK > 2.5 x ULN.
- History of alcohol abuse or binge drinking and/or any other illicit drug use or dependence within 6 months of Screening. Binge drinking is defined as a pattern of 5 (male) and 4 (female) or more alcoholic drinks in about 2 hours. As a general rule, alcohol intake should not exceed 14 units per week (1 unit = 8 ounces (240 mL) beer, 1 ounce (30 mL) of 40% spirit, or 3 ounces (90 mL) of wine).
- Use of tobacco or nicotine-containing products in excess of the equivalent of 5 cigarettes/day or 2 chews of tobacco/day.
- Part B Only: History of sensitivity reaction to midazolam, or any of the formulation components.
- Investigator site staff directly involved in the conduct of the study and their family members, site staff otherwise supervised by the investigator, and sponsor and sponsor delegate employees directly involved in the conduct of the study and their family members.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study has four parts: Part A, Part B, Part C, and Part D.
The purpose of Part A of this study is to learn about the:
- safety,
- tolerability,
- how PF-07293893 is processed by the body when multiple doses of PF-07293893 are given to healthy participants.
The purpose of Part B of this study is to understand the effect of multiple doses of PF-07393893 on the amount of midazolam when given as a single dose by mouth.
The purpose of part C of this study is to understand how PF-07293893 is changed in the body and how much PF-07293893 and it's changed forms are being removed in urine and feces after a single dose given to single participants.
The purpose of Part D is to understand the effect of multiple doses of PF-07293893 on the amount of glycogen (storage form of glucose) in the muscle of healthy participants.
Part B, C and D will be done if the results of Part A support further study of PF-07293893.

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 19 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 18 Dec 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 United States, 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. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Part A:Number of Participants With Treatment Emergent Treatment-Related Adverse Events (AEs) (time frame: Baseline up to 35 days after last dose of study intervention (approximately 11 weeks).). The study lists 17 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 18 Dec 2024.
