Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

Drug-drug interactions play an important role in clinical adverse events due to the prevalence of multi-drug therapy. Co-administration of warfarin and a statin has expanded substantially in the US over the last decades. The purpose of this study is to develop a mechanistic understanding of the role of a drug-metabolizing enzyme, CYP4F2, in the interaction between warfarin and statins. This study will test the hypothesis that lovastatin potentiates the anticoagulant effect of warfarin by inducing vitamin K-metabolizing enzyme CYP4F2 in humans, thus increasing warfarin's anticoagulant effect.

A profile link is shown only when the registered name resolves to a person record with a confident, namesake-checked match; ambiguous names stay unlinked.

Sites

1 registered facility, with the per-site recruitment status where the registry publishes one. ClinicalTrials.gov does not publish per-site enrollment counts.

Site investigator names are published by ClinicalTrials.gov only while a study recruits, so completed studies list sites without them.
