The performed study of safety and tolerability of Seroguard, solution (JSC Pharmasyntez, Russia) in patients, undergoing planned laparoscopic cholecystectomy, demonstrated that patients from the both groups had the similar safety profile

The present study was conducted as multicenter, randomized, double-blind, parallel group clinical study. After successful completion of screening procedures, patient underwent a planned laparoscopy. Randomization of patients into groups was performed on the day of surgery using envelops. The test drug or the placebo were used at the completion stage of surgery. Monitoring of patient on inpatient basis was performed for 6 days after completion of surgery. Discharge of patient from the hospital with no contraindications was possible on Day 7 of the study. In this case the follow-up of patient was performed on outpatient basis. Follow-up was performed for 4 weeks before Day 28 of the study. Study procedures aimed at evaluation of safety and tolerability of using the test drug or the placebo were identical in main and control groups.

Inclusion Criteria:

1. Male and female patients.

2. Age from 18 to 75 years, inclusive.

3. Signed informed consent form.

4. One of the following diagnoses as per International classification of diseases -10:

   4.1. K80.1 Calculus of gallbladder with other cholecystitis 4.2. K80.2 Calculus of gallbladder without cholecystitis

5. Indications for planned laparoscopic cholecystectomy.

Exclusion Criteria:

1. Recall of informed consent by patient.
2. Non-compliance with the rules of participating in the study by patient.
3. Getting pregnant.
4. Required conversion during surgery.
5. Required repeated surgery.
6. Development of diseases described in non-inclusion criteria, required use of drugs not provided by the protocol in patient.
7. Another reasons appeared during the study and interfering conduction of the study as per the protocol.

The present study was planned as double-blind, placebo-controlled study. With the aim of maximum objectification of end point, neither Medical Investigator, nor patients had access to the code of healthcare institution.

The test drug or the placebo were received by the sites as ready for use and blinded vials, 200 mL each. Each vial had individual number and identification of contents ("Drug A" or "Drug B"). Conformity of identification of Seroguard or the placebo was not disclosed to the sites.

Before surgery, the Medical Investigator prepared required number of vials according to identification of the drug on the vial and identification of the group in randomization envelope of patient. Individual number of each vial administered to a patient was recorded in documentation of site.
