What this trial studies

This clinical trial aims to evaluate the efficacy and safety of ganciclovir capsules in patients suffering from refractory moderate-to-severe allergic rhinitis. Participants will be randomly assigned to receive either ganciclovir or a placebo for two weeks, alongside a nasal spray treatment. The study will assess improvements in nasal symptoms and quality of life, as well as monitor for any adverse effects. Various tests will be conducted to ensure participants meet the necessary criteria for inclusion in the trial.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 65 with moderate-to-severe perennial allergic rhinitis that has not improved with standard treatments.

Not a fit: Patients with hypersensitivity to ganciclovir or those experiencing acute viral infections will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the quality of life for patients with severe allergic rhinitis who have not responded to other therapies.

How similar studies have performed: Previous clinical observations have indicated that ganciclovir may effectively treat refractory allergic rhinitis, suggesting potential success for this trial.

13. Participants with a known history of malignancy within 5 years prior to screening.
