An interventional study of Arbidol in Allergic Rhinitis, sponsored by Zheng Liu. Recruiting at 2 sites in China. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2025-05-07.
Sponsored by Zheng Liu · Not applicable, Interventional, and Treatment
The most important treatment for AR is topical nasal medications (including nasal corticosteroids, nasal antihistamines, nasal decongestants, and nasal saline irrigation etc.), which are still limited. Arbidol may inhibit molecular targets involved in the pathogenesis of AR. This study intends to explore the effect of Arbidol in the treatment of allergic rhinitis and evaluate its efficacy and safety.
Allergic rhinitis (AR) is a non-infectious inflammatory disease of the nasal mucosa mediated by Immunoglobulin E after exposure to allergens. AR has become a major chronic inflammatory disease of the respiratory tract, which has a serious impact on the quality of life of patients and social economy. The most important treatment for AR is topical nasal medications (including nasal corticosteroids, nasal antihistamines, nasal decongestants, and nasal saline irrigation etc.). However, even if patients are treated completely according to the standard diagnosis and treatment strategy, a considerable number of patients still do not achieve satisfactory treatment results. Arbidol is a medicine for the prevention and treatment of influenza. Based on our previous laboratory data, Arbidol may inhibit molecular targets involved in the pathogenesis of AR. In order to make the treatment of AR more effective, timely and convenient, this study intends to explore the effect of Arbidol in the treatment of allergic rhinitis and evaluate its efficacy and safety.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.
The study may name a correction formula and a limit in milliseconds, often around 450–480.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

The protein level of molecular biomarkers in nasal epithelial cells
The level of molecular biomarkers in nasal epithelial cells at baseline (day 0, prior to treatment), day 14 will be measured by western blotting.
Time frame: 14 days
The mRNA level of inflammation molecular biomarkers in nasal epithelial cells
The relative mRNA level of inflammatory cytokines (including IL-4, IL-13, CCL11, CCL24, CCL26 etc.) in nasal epithelial cells at baseline (day 0, prior to treatment), day 14 will be measured by Real-time PCR.
Time frame: 14 days
The level of inflammation molecular biomarkers in nasal lavage fluid
Investigate the change of inflammation molecular biomarkers using sample of nasal lavage fluid. Biomarkers including IL-4, IL-13, CCL11, CCL24, CCL26 and IgE etc. in nasal lavage fluid at day 7 day 14 were detected to compare the changes of molecular indices relative to baseline at day 0.
Time frame: 14 days
Changes from baseline in daily total nasal symptom score (TNSS) during 2 weeks of treatment.
The TNSS for allergic rhinitis was used to evaluate the rhinitis-related symptoms and quantity of life scores. Changes from baseline in daily total nasal symptom score (TNSS) during 2 weeks of treatment. The Total Nasal Symptom Score (TNSS) is the sum of four symptom scores, rhinorrhea, nasal congestion, nasal itching, and sneezing, where each symptom is scored on a scale of 0 to 3.
Time frame: 14 days
Started Jul 2024 (actual). Primary completion is estimated for Jun 2025, 11 months after the start.
Of 66 non-industry interventional studies with no phase under Rhinitis, Allergic, half reached primary completion within 13 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 28. This study's planned 11 months is below that.
Counting every sponsor, half of 87 studies reached it within 11 months; a quarter within 4 and three quarters within 27.
How these figures are worked out, and which studies are left out of them.
