NCT ID NCT07563894
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-stage study in 16 healthy adults aims to compare how well a new film-coated tablet of the experimental drug PF-07799933 is absorbed versus an older tablet form. It also checks whether taking the drug with a high-fat meal or with an acid-reducing medication changes drug levels in the blood. The results will guide how the drug should be taken in future clinical trials.
