Radioactive microdose reveals Drug's journey in healthy men
NCT ID NCT07578636
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This Pfizer study in 9 healthy men uses a tiny amount of radioactive carbon to track how the experimental drug PF-07799544 is absorbed, distributed, and eliminated from the body. Participants receive the drug by mouth and by IV, and samples of blood, urine, and stool are collected. The goal is purely to understand the drug's behavior, not to treat any condition.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
PF-07799544 (with a radioactive carbon tracer)
What this could lead to
If successful, this study will help researchers understand how PF-07799544 is absorbed and removed from the body, which can guide future dosing and development.
What could go wrong
This is a very early Phase 1 study with only 9 healthy men. It is designed to gather information, not to treat any disease. The radioactive tracer is safe at these low levels, but the drug itself may have unknown side effects.
