Study of the Safety and Tolerability of the Broad-spectrum Probiotic Medicine "AS-Probionorm"

Dosage form of the medicine "AS-Probionorm" (powder for the preparation of solution for oral administration) - 1 g in a sachet.

Pharmacological group - Antidiarrheal drugs. Antidiarrheal microorganisms. Microorganisms that produce lactic acid.

Introduction:

Acute intestinal infections (AII) are one of the pressing health problems in all countries. The complexity of their treatment is associated with the massive irrational use of antibiotics and chemotherapeutic drugs, which has led to the development of multidrug resistance in pathogens. Therefore, the modern strategy for the treatment of acute intestinal infections gives priority to therapeutic measures aimed at correcting intestinal microbiocenosis to eliminate the source of infection localized in the intestine.

The main idea is to conduct clinical studies of the domestic medicinal probiotic medicine "AS-Probionorm" based on the association of lactic acid bacteria of targeted action for oral use for the treatment of inflammatory and infectious diseases of the human gastrointestinal tract.

During preclinical trials, it was established that the drug exhibits high antimicrobial activity, therapeutic and prophylactic effectiveness, as well as safety during use.

The purpose of the study was to study the safety and tolerability of the study medicine "AS-Probionorm" in healthy study subjects.

Phase I of the clinical trial of the drug included 20 healthy subjects of both sexes aged 18-50 years. Clinical and laboratory parameters to characterize the safety of the drug: medical history, physical examination, ECG, general and biochemical blood tests, urine and stool tests.

Study design: open-label, single-center, phase I clinical trial. Dosage regimen: 1 sachet (1 g) 2 times a day with an interval of 12 hours. The study drug should be used 15-20 minutes before meals in the morning and evening. Before use, the medicine is mixed with 30-50 ml of boiled water at room temperature, resulting in a cream-colored suspension. The resulting water suspension should be drunk. The duration of taking is 7 days.

The study will be carried out on an outpatient basis. The total duration of study subjects' participation in the study is 21 days. On days 1, 8, 15, 21, a medical examination and laboratory tests will be carried out.

The duration of the study course of 21 days is determined by studying the possibility of developing local toxic and allergic reactions at the dosages recommended to identify the therapeutic effect.

Tolerability of the drug will be assessed based on subjective symptoms and sensations reported by patients and objective data obtained by the investigator during the study. The frequency of occurrence and nature of adverse reactions are also taken into account. The degree of tolerability of the study drug will be determined by three gradations: intolerance, absence of undesirable drug reactions (side reactions), undesirable drug reactions (side effects) not classified as serious.

Statistical analysis of data is carried out based on the results of collecting anamnestic, clinical data, as well as data from laboratory and instrumental studies. The volume of consultations, examinations and concomitant treatment carried out before the study is also recorded. Data collection will be carried out using an approved form - Individual Registration Card.

Ethical and legal issues in clinical research Ethical principles: The clinical trial will be conducted in accordance with the principles formulated by the 18th World Medical Assembly (Helsinki, 1964) and the ICH guidelines for good clinical practice (GCP).

Laws and Regulations: The clinical trial will be conducted in accordance with all international laws and guidelines, as well as national laws and regulations in accordance with any applicable guidelines.

Data collection, maintenance and storage of records. Data collection will be carried out electronically and, partially, in paper form.

The Investigator must maintain all research documentation (electronic and paper) in confidence and take steps to prevent accidental or premature destruction of this documentation.

The Investigator must retain all study documentation for a minimum of fifteen (15) years after completion or premature termination of the clinical trial.

However, if a longer period is required, applicable legal requirements must be taken into account.

The investigator must notify the sponsor before destroying any important study documents following completion or premature termination of a clinical trial.

Financing and insurance. All financing and insurance issues will be determined in the agreement concluded between the Sponsor and the Contractor.

Publications. The Investigator agrees not to publish or report the study and/or its results without the prior written permission of the study sponsor, noting that the sponsor will not withhold such permission without reasonable cause. The researcher will not use the sponsor's name in any promotional material or publication without the sponsor's prior written consent. The sponsor will not use the name of the investigator and/or his/her collaborators in promotional materials or publications without first obtaining his/their written consent. The sponsor has the right to publish the study results at any time.
