A Study to Learn if the Study Medicine Called Fluconazole Changes How the Other Body Processes the Study Medicine PF-07248144

Belgium12 participantsStarted 2025-08-26

Plain-language summary

The purpose of the study is to learn how the study medicine called fluconazole changes how the body processes the other study medicine called PF-07248144. The study will also look at the safety, tolerability, and how the medicine is changed and removed from the body after taking PF-07248144 alone compared to when it is taken with fluconazole. Fluconazole can change how your body processes some medications so it may change the body's processing of PF-07248144. Multiple blood samples will be collected up to 10 days after each dose of PF-07248144 to determine how much PF-07248144 is in the blood at different times. This will help characterize the pharmacokinetics (pharmacokinetics helps us understand how the drug is changed and eliminated from your body after you take it) of PF-07248144 alone and when taken with fluconazole.

Inclusion Criteria * Male or female of nonchildbearing potential ≥ 18 years of age, inclusive, at screening who are overtly healthy as determined by medical evaluations including medical history, physical examination, laboratory tests, vital signs and 12-lead ECGs. * Body mass index (BMI) of 18-32 kg/m2; and a total body weight \>50 kg (110 lb). Exclusion Criteria * Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurological, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at the time of dosing). * Use prescription or nonprescription drugs and dietary and herbal supplements within 14 days or 5 half-lives (whichever is longer) prior to the first dose of study intervention.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
