Efficiency and Safety of the Drug Ingaron (Interferon-gamma Human Recombinant) in the Treatment of Chronic Prostatitis

Phase 3

Completed

• Conditions: Chronic Prostatitis
• Interventions: Drug: Interferon gamma human recombinant (IFN-G)

• Registration Number: NCT05378646
• Lead Sponsor: SPP Pharmaclon Ltd.

Brief Summary

The primary purposes of the study are to evaluate the effectiveness of Ingaron in the complex therapy of chronic prostatitis, to assess the safety of using Ingaron in patients with chronic prostatitis.

Detailed Description

Literature data and the results of preclinical studies of interferon-gamma, as well as the features of the immunopathogenesis of chronic prostatitis, show the expediency of studying the use of Ingaron in this pathology.

The study was conducted to compare the efficacy and safety of Ingaron in combination with standard therapy with its subcutaneous administration and standard therapy in patients with chronic prostatitis.

The study was planned to include 50 male patients aged at least 18 years with a confirmed diagnosis of chronic prostatitis.

In the course of the study, Ingaron was administered at a dose of 500,000 IU once a day, every other day. In addition to Ingaron, patients received antibiotic therapy, anti-inflammatory drugs, alpha-blockers (if necessary). Magnetic laser therapy and prostate massage were also provided.

The patients were divided into 2 groups: main and control.

Arm && Interventions

Group	Intervention	Description
Experimental	Interferon gamma human recombinant (IFN-G)	Patients received Ingaron 500,000 IU subcutaneously once a day, every other day. The course of treatment is 7 injections. The first injection was given on the first day of active therapy. Subsequent injections were given every other day. The period of active therapy was 14 days.

Primary Outcome Measures

Dynamics of the total score and improvement in the quality of life on the scale IPSS.	Day 13	The sum of points was assessed, as well as the symptom complex on the basis of the "IPSS" questionnaire - the international system for the total assessment of symptoms of prostate diseases in points (WHO, 1992). The severity of symptoms was assessed from 0 to 6 points.; symptoms of prostate diseases in points (WHO, 1992). The severity of symptoms is rated from 0 to 6 points.
