Remaxol® in Mechanical Jaundice of Non-malignant Origin
Study Details
Study Description
Brief Summary
The purpose of this study is to assess the safety and efficacy of Remaxol (succinate + methionine + inosine + nicotinamide; POLYSAN Ltd., Russia) infusions at dose 400 and 800 ml to treat mechanical jaundice of non-tumor cause during the first week after surgery.

Phase 3 |
Detailed Description
The study will be performed in in-hospital patients with obstructive jaundice cause by conditions other than tumor (predominantly by cholelithiasis; ICD-10 codes K80 and K83.1). The patients will be screened in the 15 days preceeding the appointed drainage surgery. The treatment will be started in the first 6 hours after the drainage surgery and continue for 7 days.
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 Remaxol 400 ml IV + Ringer solution 400 ml IV for 7 days.
Group II: treatment with Remaxol 800 ml IV for 7 days. Group III (control): Ringer solution 800 ml IV for 7 days.
Physical examination data, vital signs, biochemistry panel (including bilirubin, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, GGTP) will be assessed on days 1-8, on day 11 and day 14.
Diagnostic abdominal ultrasound will be performed before surgery and on days 3 and 8.
Neurophysiological test for the evaluation of the degree of encephalopathy will be performed before surgery, on days 3, 5, 8, and 14.
All patients will be followed up for 14 days.

Outcome Measures
Primary Outcome Measures
- Days to regression of jaundice [14 days]
Time (days) from the date of drainage surgery to the reduction of the total bilirubin level down to 50 μmol / l, in experimental (Remaxol®) and control (Placebo) groups
Secondary Outcome Measures
- Disappearance of cytolysis (normal alanine aminotransferase and aspartate aminotransferase serum levels) on day 5 [5 days]
Proportion of patients in study groups who reached normal serum levels of alanine aminotransferase and aspartate aminotransferase on day 5 from the start of treatment
- Disappearance of cholestasis on day 5 [5 days]
Proportion of patients in study groups who reached normal serum levels of alkaline phosphatase, GGTP, total bilirubin, and direct bilirubin on day 5 from the start of treatment
- Disappearance of encephalopathy on day 5 [5 days]
Proportion of patients in study groups who had normal brain functioning on day 5, as reflected by the neurophysiological test for the evaluation of the degree of encephalopathy
- Serum bilirubin [14 days]
Dynamics of total and direct bilirubin serum levels against baseline values and between visits in the study groups
- Serum enzymes [14 days]
Dynamics of serum alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and GGTP against baseline values and between visits in the study groups
- Liver function [14 days]
State of liver protein synthesis function (as reflected by serum levels of total protein, albumin, fibrinogen) against baseline values and/or between visits
- Kidney function [14 days]
State of kidney function (serum creatinine) against baseline values and/or between visits
- Proportion of patients with complications of jaundice [14 days]
The number of patients in the study groups who developed complications in the postoperative period which were, according to the researcher's assessment, causally related to the obstructive jaundice (for example, purulent cholangitis, sepsis, kidney failure).
