Low recruitment

The study is designed to assess the safety and efficacy of different doses and dosing regimens of Runihol, tablets, enteric coated, produced by "NTFF" POLYSAN" (Russia), in prevention of liver disease progression in patients with non-alcoholic fatty liver disease and metabolic syndrome.

The aim of this study is a comparative assessment of the safety and efficacy of different doses and dosing regimens of Runihol drug tablets, enteric coated, produced by "NTFF" POLYSAN "(Russia) and placebo tablets, enteric coated, produced by" NTFF "POLYSAN" (Russia), when administered to patients with non-alcoholic fatty liver disease and metabolic syndrome.

Design: a multicenter, prospective, randomized, double-blind, placebo-controlled comparative study in parallel groups.

The study will be performed on the outpatient basis under the supervision of the physician-researcher who will be in charge of screening and the whole course of study drug therapy.

The study consists of the following periods:

• Screening - preliminary examination of the eligible patients (duration 14 days).
• The period of therapy - the use of the study drug Runihol®, tablets, enteric coated, produced by "NTFF" POLYSAN "(Russian) or placebo tablets, enteric coated, produced by" NTFF "POLYSAN" LLC (Russia), during 84 days (12 weeks).

Following screening, patients who meet the inclusion criteria and have no criteria for exclusion will be randomly assigned into three study groups in the proportion of 1: 1: 1):

• Group I: treatment with Runihol®, 1 tablet 3 times a day, and placebo tablets, 1 tablet three times a day, for 84 days (12 weeks).
• Group II: treatment with Runihol®, 2 tablets 2 times a day, morning and evening, and placebo tablets, 2 tablets once a day, in the afternoon, for 84 days (12 weeks).
• Group III: patients will receive placebo tablets, 2 tablets 3 times a day, for 84 days (12 weeks).

Patient assessment will be carried out in the course of 6 visits.

Screening:

Visit 2 (Day 15) - evaluation of the patient based on the results of physical examination, assessment of vital signs, laboratory complex (clinical and biochemical blood tests, PTI, determination of homocysteine in the blood serum, the total urine analysis) and instrumental (ECG) studies; control of intake of study medication / placebo, evaluation of concomitant therapy, checking patient diary, registration of AEs.

Visit 3 (Day 29) - evaluation of the patient based on the results of physical examination, assessment of vital signs, laboratory complex (clinical and biochemical blood tests, PTI, determination of homocysteine in the serum / plasma, total urine analysis) and instrumental (ECG ) investigations; control of intake of study medication / placebo, evaluation of concomitant therapy, checking patient diary, registration of AEs.

Visit 4 (Day 57) - evaluation of the patient based on the results of physical examination, assessment of vital signs, laboratory complex (clinical and biochemical blood tests, PTI, determination of homocysteine in the serum / plasma, total urine analysis) and instrumental (ECG ) studies; control of intake of study medication / placebo, evaluation of concomitant therapy, checking patient diary, registration of AEs.

Visit 5 (Day 85) - evaluation of the patient based on the results of physical examination, assessment of vital signs, laboratory complex (clinical and biochemical blood tests, PTI, determination of homocysteine in the serum / plasma, insulin resistance index calculation, the total urine analysis) and instrumental (ECG, ultrasound of the abdomen) investigations; control of intake of study medication / placebo, evaluation of concomitant therapy, checking patient diary, registration of AEs.
