Investigation of β-hydroxybutyrate Supplementation as Chemoprevention in Familial Adenomatous Polyposis
Trial Parameters
Brief Summary
The aim of this study is to evaluate the potential of BHB supplementation as a novel strategy to impede the development and progression of intestinal adenomas in individuals with FAP, thus potentially reducing the need for frequent upper endoscopies and colonoscopies and preventing the need for risk-reducing surgical intervention.
