Clinical Trial Summary

The goal of this clinical trial is to learn about the clinical efficacy and safety of ganciclovir (GCV) capsules in the treatment of refractory moderate-to-severe allergic rhinitis. The main questions it aims to answer are: 1. Whether ganciclovir improve nasal symptoms and life quality in patients with refractory moderate-to-severe allergic rhinitis. 2. Whether ganciclovir is safe for the treatment of allergic rhinitis. Participants with refractory moderate-to-severe allergic rhinitis will be included in the trial based on the inclusion and exclusion criteria, and randomized into experimental and control groups. The two groups will be treated with blinded ganciclovir capsules or placebo for two weeks, with the background therapy of mometasone furoate aqueous nasal spray. A placebo is a look-alike capsule that contains no active drug. Nasal symptom scores, nasal secretions, blood samples and adverse events will be collected during the visits. Researchers will compare the experimental and control groups to see whether ganciclovir improve symptoms and is safe for the treatment of refractory moderate-to-severe allergic rhinitis.

Clinical Trial Description

Ganciclovir (GCV) is clinically used for the treatment of DNA viral infections. In clinical practice, we have found that patients with refractory AR have improved nasal symptoms after oral administration of ganciclovir. In clinical practice, we have found that patients with refractory AR have improved nasal symptoms after oral administration of ganciclovir. To further explore the role of GCV in the treatment of refractory allergic rhinitis, we have conducted an interventional non-randomised cohort study of GCV for refractory AR. The results found that 65% of all refractory AR patients included in the observation were effectively treated with GCV. Based on the previous discovery in the clinical practice, the conjecture is proposed that ganciclovir may improve symptoms in allergic rhinitis patients, in particular the patients with refractory moderate-to-severe allergic rhinitis. Thus, the randomized, double-blind, placebo-controlled clinical trial was designed to explore the validity of this hypothesis. The research involves three phases: screening phase(Day-14±2~0)；baseline (Day1)；treatment phase (Day1~14)；follow-up phase (Day14~28). In the screening phase, anterior rhinoscopy, serum specific IgE test, skin prick test, total nasal symptom scores (TNSS), visual analogue scale (VAS) scores, Allergic Rhinitis Control Test (ARCT) score will be performed for participants. Participants who meet the inclusion and exclusion criteria will enter the treatment phase and receive the medication for two weeks. At the end of the treatment, researchers will follow participants for two weeks to track efficacy and safety. Researchers will collect participants' symptom scores, nasal secretions and blood. The biological specimens will be used to test for indicators that support the determination of therapeutic efficacy. Vital signs, blood routine examination, urine routines, liver function test, kidney function test and electrocardiograms will be measured for participants before and after treatment to assess the safety of ganciclovir. The data collected will be statistically analyzed to examine the clinical efficacy and safety of ganciclovir capsules in the treatment of refractory moderate-to-severe allergic rhinitis. ;
