Systems Biological Assessment of Statin Effect on Vaccine Responses
In Brief
A Phase 4 clinical trial evaluating Atorvastatin and Quadrivalent seasonal influenza vaccine for Vaccine Response. Completed, enrolled 63 participants across 1 site.
Detailed Summary
This study is being done to answer the question: Does the use of statin lipid-lowering medication change the effect of influenza vaccine? The research team will use the knowledge gained from answering this question to understand how this medication affects long-lasting immune responses to vaccines. The researchers will study the immune response to the influenza vaccine in the blood (where antibodies are). The team will also look at how statin therapy affects the bacteria that live in the gut by collecting stool samples. To be in this research, participants must be adults willing to receive vaccines.
Study Details
Timeline
Interventions
Atorvastatin is a lipid-lowering agent of the statin family that functions by blocking a rate-limiting enzyme, Hydroxymethylglutaryl-CoA (HMG-CoA) reductase, in lipid metabolism. This agent is commonly used for primary and secondary prevention of dyslipidemia. Participants will be asked to take Atorvastatin 80 mg daily at night, for 4 weeks prior to the vaccination, and continue the statin therapy for 4 weeks after vaccination. The 80mg dose of atorvastatin allows for evaluation of the immunologic effects of statin medication with a short duration of therapy prior to vaccination.
The FDA-approved quadrivalent seasonal influenza vaccine contains four distinct strains: two influenza A viruses and two influenza B viruses. The approved seasonal QIV will be purchased from the manufacturer to be given for each season of influenza.
