Pilot Study to Evaluate the Plasma Profile of Revifast

Nutrient; Excess Clinical Trial

Official title: Randomized, Single-blind, Cross-over Pilot Study to Evaluate the Plasma Profile of Resveratrol Following an Oral Administration of Either Revifast® (Resveratrol From Polygonum Cuspidatum Extract Siebold & Zucc - Root Supported on Magnesium Hydration With a Weight Titer of Min. 30% Resveratrol) and Unsupported Pure Resveratrol

Status Completed

Clinical Trial Summary

The purpose of this study is to evaluate in 6 subjects aged between 18 and 60 years the peak blood (plasma profile) of two formulations, indistinguishable from each other, containing:

A) 180 mg natural Resveratrol (Polygonum cuspidatum 98%) B) 180 mg of Revifast® (resveratrol from supported on Magnesium hydroxide).

Clinical Trial Description

The study will be randomized, controlled, single blind, cross-over, using the two granular compounds in capsules A and B, indistinguishable from each other, dissolved in aqueous solution and administered orally. either A:180 mg natural Resveratrol (Polygonum cuspidatum 98%) deriving from galenic preparation from the IRRE pharmacy - Istituto Riuniti based in Cannara in via Vittorio Emanuele II 23.

B) 180 mg of Revifast® (mixture of resveratrol from Polygonum cuspidatum extract Siebold & Zucc. Root supported on Magnesium hydroxide).

Cross-over refers to a type of clinical study in which each individual receives each of the treatments consecutively.

PHASE I: The subjects will be given, on the first day, in the morning on an empty stomach, a solution of content A or B obtained by dissolving the contents of the capsule in water which will then be taken orally. Samples of 2 ml of venous blood in a tube containing EDTA will be taken from a vein in the arm using a cannula at 0 min (fasting before administration), 15 min, 30 min, 60 min, 90 min, 120 min, 180 min .

WASH-OUT: 1 day. PHASE II: On the third day, the person who had taken the solution A will take the solution B, and vice versa, with the same methods and times described above.

The study will have a total duration of 6 weeks divided as follows:

• Pre-monitoring phase, enrollment of subjects, random assignment in two arms 1 and 2 each consisting of 3 subjects and signature of the informative consent regarding the adhesion to the study protocol (1 week);

• 1 week for taking samples and storing them for routine chemical / biochemical analyzes carried out at the Crabion S.R.L. accredited center based in Corciano in via Amilcare Ponchielli 8 (on the first day, arm 1 will start treatment with solution A; on the second day, this arm will wash-out and arm 2 will start treatment with solution A; on third day on arm 1 will start the treatment with solution B and arm 2 will wash-out; on the fourth day arm 2 will carry out the treatment with solution B; once the routine analyzes have been carried out, on the fifth day the frozen samples will be sent to the Department of chemistry, biology and biotechnology of the University of Perugia for subsequent extraroutine analyzes).

• 2 weeks for carrying out the pharmacological and metabolomic analyzes of extraroutins performed at the Department of chemistry, biology and biotechnology of the University of Perugia;

• 2 weeks for carrying out statistical tests and processing the data obtained. ;
