What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to understand how itraconazole affects the body's processing of another drug, PF-07248144, an experimental treatment. Researchers seek to determine whether taking PF-07248144 alone or with itraconazole alters its absorption, breakdown, and elimination. Participants will take these medicines in different stages, with blood samples collected to monitor PF-07248144 levels. The trial seeks healthy men and women who cannot have children and have not recently used certain drugs or supplements. As a Phase 1 trial, this research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new treatment.

Will I have to stop taking my current medications?

Yes, you will need to stop taking any prescription or nonprescription drugs, dietary, and herbal supplements at least 14 days before starting the study. You also cannot use certain foods or drugs that affect specific enzymes (CYP2C9 or CYP3A4) during the study and for 10 days after the last dose.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Researchers are studying the safety of PF-07248144 when used alone and with itraconazole. This study examines how itraconazole might affect the processing of PF-07248144 in the body. Previous research suggests that patients have tolerated PF-07248144 well.

Itraconazole, already FDA-approved for treating fungal infections, has had its interactions with other drugs studied before. The main goal of this study is to determine if itraconazole changes the amount of PF-07248144 in the blood.

As an early-stage study, the focus is on safety and tolerability. So far, no serious side effects have been reported, but this type of study is designed to closely monitor for any potential issues.12345

Why are researchers excited about this trial's treatments?

Researchers are excited about the combination of PF-07248144 and itraconazole because it offers a new approach to understanding drug interactions that could enhance the effectiveness of existing treatments. Unlike standard antifungal or cancer treatments that are often used independently, this study explores how itraconazole can potentially influence the metabolism of PF-07248144, a novel compound. This interaction could lead to improved efficacy or safety profiles, opening the door for more personalized and effective therapy options in the future.

What evidence suggests that this trial's treatments could be effective?

This trial will evaluate the interaction between PF-07248144 and Itraconazole. Research has shown that PF-07248144 targets proteins that aid cancer cell growth, making it a promising treatment for some cancers. Participants will receive PF-07248144 both alone and with Itraconazole, which alters how the body processes medications and might enhance PF-07248144's effectiveness. Although no direct proof yet exists that these two drugs work well together, the study aims to determine their interaction. Early results suggest that PF-07248144 might be effective on its own, but more research is needed to confirm its effectiveness, especially when combined with Itraconazole.12567
