The study object of this clinical trial is CanProFem-AK, 100 mg suppositories. The Pharmacological group - Antifungal drug for external use. The active drug substance is the antifungal antibiotic Roseofungin 100 mg, which was developed at the "Research and Production Center of Microbiology and Virology".

According to the aims and objectives of the phase I clinical trial, the primary parameter is the study of safety and tolerability throughout the entire duration of the trial.

The phase I clinical trial of the drug CanProFem-AK 100 mg included 20 healthy female participants aged 18 to 40 years, who are on 6-12 days of their menstrual cycle. The clinical and laboratory parameters to characterize the safety of the drug: specific clinical signs and symptoms of particular importance, medical history, physical examination, biochemical analysis of blood, complete blood count with white blood cell count, and complete urine analysis.

Selection and Exclusion of Subjects: Before inclusion in a clinical trial, each participant must first sign an Informed Consent Form for Participation in the Study, followed by a screening examination, including a variety of procedures, medical history, and physical examination. Each participant in the trial will be assigned an identification number.

Study Design: open-label, single-centre, phase I clinical trial. The total duration of participation in a study is one day. The administration scheme of the drug includes the vaginal insertion of one suppository for each participant, followed by medical observation of the participants' conditions at 3, 6, 9, 12 and 24 hours after administration.

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

This clinical trial will be conducted following the principles formulated by the 18th World Medical Assembly (Helsinki, 1964) and the ICH guidelines for good clinical practice (GCP), as well as with all international and national laws and guidelines.

The study object of this clinical trial is CanProFem-AK, 100 mg suppositories. The Pharmacological group - Antifungal drug for external use.

Fungal infections are one of the most demanding and unresolved problems of modern medicine. The number of fungal infections is growing due to the increase in the number of people with immunodeficiency diseases, oncohematological pathology, organ transplants, nursing newborns, the coronavirus pandemic, while the role of fungi that were previously considered non-pathogenic is increasing. Among fungal diseases, candidiasis, caused by fungi of the genus Candida, is of particular importance. Genital, vulvovaginal, candidiasis is a very common phenomenon. Taking into account the prevalence of candidiasis, as well as numerous cases of resistance of pathogenic fungi to drugs, an urgent task is to create new domestic effective antifungal drugs for their treatment.

Scientists from the "Research and Production Center of Microbiology and Virology" developed a new pharmaceutical antifungal drug "CanProFem-AK"® in the form of a suppository for the treatment of vaginal candidal infections. The active drug substance is the original antifungal antibiotic Roseofungin, produced by a strain of soil microorganism, that has high activity against pathogenic fungi - causative agents of human mycoses. Preclinical trials of the drug shown its safety and effectiveness in the treatment of vaginal candidiasis. The trials demonstrated that the drug exhibits high antifungal activity, therapeutic efficacy, and safety in use.

The phase I clinical trial of the drug CanProFem-AK 100 mg included 20 healthy female participants aged 18 to 40 years, who are on 6-12 days of their menstrual cycle. The clinical and laboratory parameters to characterize the safety of the drug were: specific clinical signs and symptoms of particular importance, medical history, physical examination, biochemical analysis of blood, complete blood count with white blood cell count, and complete urine analysis.

Study design: open-label, single-centre, phase I clinical trial. Dosage regimen: vaginal administration of one suppository of the studied drug (CanProFem-AK, 100 mg). The total duration of participation in a study is one day. The administration scheme of the drug includes the vaginal insertion of one suppository for each participant, followed by medical observation of the participants' conditions at 3, 6, 9, 12 and 24 hours after administration. Repeated blood and urine laboratory tests will be performed after 24 hours. Participants of the study will be closely monitored for 24 hours after the initial administration of the drug to detect any immediate adverse events. If the subject experiences an immediate adverse event, appropriate treatment will be provided.

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

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

Ethical and legal issues in clinical research: This clinical trial will be conducted following the principles established by the 18th World Medical Assembly (Helsinki, 1964) and the ICH guidelines for good clinical practice (GCP). It will be conducted in compliance with all relevant international laws and guidelines, as well as the national laws and regulations of the countries where it is conducted.
