Official title: Clinical and Immunological Study of the Efficacy and Safety of Combined Treatment of Patients With Severe Herpes Simplex (HSV) Infection) by Acyclic Nucleoside Valacyclovir and Interferon Inducer Kagocel

Status Completed

Clinical Trial Summary

This study examined the efficacy, safety and benefits of modern treatment and changes in the dynamics of the life of adult patients quality with severe herpes simplex in the current medical practice when combined therapy by acyclic nucleoside Valacyclovir and antiviral agent Kagocel versus monotherapy by Valacyclovir. This study also evaluated the structure of herpesvirus infections and the rate of mixed variants of the course, the rate of exacerbations of herpes simplex, the time of disappearance of human herpesvirus isolation and the features of the immune phenotype of patients taking different types of therapy.

Clinical Trial Description

This study was a comparative post-registration prospective non-interventional (observational) scientific study.

This research did not include any procedures or medical interventions except those recommended in the local clinical guidelines and international standards of care.

• demography

• disease severity (mild, moderate, severe, continuous relapses)

• data of anamnesis (hereditary and family anamnesis, duration of herpes simplex disease, previous illnesses, duration of treatment, previous treatment of herpes simplex and its efficacy, allergic anamnesis, epidemiological anamnesis, rate and duration of herpes relapses over the past year (with indication of the location of herpes simplex rashes), main diagnosis and complications, ICD-10 code, date and time of the last exacerbation, causes of exacerbation)

• verification of inclusion criteria

• verification of non-inclusion criteria

• prescribed therapy (trade name and prescription scheme, rate, method of administration)

• laboratory tests (4 timelines: 1 - first 6-48 hours; 2 - 6 days after starting of therapy; 3 - 30 days; 4 - 4 months): clinical and biochemical blood tests; serological diagnostics with determination of herpes virus infections's markers: IgM, IgG-HSV1, HSV2; hospital screening of venous blood: anti - HIV-1,2; anti-HCV-total, HBsAg, CSR; microbiological seeding from the tonsils, posterior pharyngeal wall with determination of drug sensitivity; PCR of blood, saliva and/or rash elements; immune status by laser flow cytometry: CD3+, CD4+, CD8+, CD4+/CD8+, CD16+, CD19+; serum immunoglobulins: IgA, IgM, IgG, IgE total.

• medical anamnesis (4 timelines: 1 - first 6-48 hours; 2 - 6 days after starting of therapy; 3 - 30 days; 4 - 4 months) or clinical efficacy: the presence and rate of exacerbations of the disease orolabial, genital and other sites; local complaints; the rate of occurrence of and general symptoms; the rate of epithelialization of the rash's morphological elements; duration of recurrence of the herpes simplex virus and speed of onset of epithelialization; the rate of relapses and exacerbations of herpes simplex on the background of suppressive therapy

• taking other drugs during the study (trade name, prescription scheme)

• compliance with the drugs regimen

• timelines: data of signing the informed consent, start date of the study, date of each patient visit, end date of the study, start date and end date of the taking medicines, duration of patient follow-up)
