Healthy Volunteers Clinical Trial
Official title:
INvestigation of the Gut microbiomE and STatin Response (INGEST)
There is evidence that the bacteria that naturally reside in the gut can influence how well we respond to medications. Therefore this study will look at how rosuvastatin, a medication used to lower cholesterol levels, may change the bacteria in the gut. Investigators will also examine how the gut bacteria will affect the ability of rosuvastatin to lower cholesterol levels. There will be 4 study visits over the course of about 16 weeks.The expected duration of the study is 2 years. Investigators plan to enroll 100 healthy volunteers during that time.
The gut microbiome plays an important role in the metabolism of xenobiotics and contributes to the variation in drug response. Atorvastatin, simvastatin and rosuvastatin, three of the most commonly prescribed statin medications, also display evidence for modulation by the gut microbiome.The objective of this study is to understand the interaction between the gut microbiome and host drug response to statin therapy using 16S rRNA sequencing, metagenomics sequencing and bile acid metabolomics. Aim 1: To compare changes in the gut microbiome in healthy volunteers randomized to an 8-week intervention with rosuvastatin 10mg daily or placebo. Aim 2: To determine the relationship with gut microbiome, fecal bile acid composition, serum FGF19 levels and the change in plasma LDL-C with rosuvastatin. This is a randomized, placebo controlled trial to investigate the effects of rosuvastatin on the gut microbiome, fecal bile acids and FGF19 levels. Healthy volunteers will be randomized to rosuvastatin 20 mg daily or placebo for eight weeks in a 2:1 ratio. Participants will be blinded to treatment assignment. Stool and blood will be collected at baseline, 8 weeks, and 12 weeks for 16S sequencing, plasma lipid assays, bile acid metabolites and FGF19 assays. A subgroup of participants at the tails of LDL-C response will undergo metagenomics sequencing. ;
