A Study of IL4Rα Monoclonal Antibody in Patients With Seasonal Allergic Rhinitis(SAR).

Phase 2
Active, not recruiting
Conditions
Allergic Rhinitis
Interventions
Biological: GR1802 injection
Biological: Placebo
Registration Number
NCT06315426
Lead Sponsor
Genrix (Shanghai) Biopharmaceutical Co., Ltd.
Brief Summary

Allergic rhinitis (AR) is a non-infectious chronic inflammatory disease of the nasal mucosa mainly mediated by immunoglobulin E after exposure to allergens in atopic individuals. The typical symptoms of AR are paroxysmal sneezing, watery rhinorrhea, itching, and nasal congestion, which may be accompanied by ocular symptoms, including eye itching, tearing, redness, and burning sensation, which are more common in patients with hay fever allergies. Bronchial asthma is associated with bronchial asthma in 40% of patients with AR, suggesting a comorbid feature of allergic disease.

Main

Exclusion Criteria
  1. Other nasal comorbidities or co-morbidities/states that may be present at the time of screening that affect efficacy determination.
  2. Subjects whose allergen exposures in their home or work environments may be expected to change significantly during the trial period.
  3. Subjects with poorly controlled recent asthma conditions.
  4. Presence of current or past history of infection of special concern, e.g., active tuberculosis, helminthic infections, severe herpes virus infections, etc.
  5. Previous use of anti-interleukin 4 receptor alpha subunit (IL4Rα) monoclonal antibody.
  6. Have a serious underlying medical condition that, in the opinion of the investigator, may pose a risk to subject safety by participation in a clinical trial.

Primary Outcome Measures
NameTimeMethod
Change from Baseline in rTNSS( reflective total nasal symptom scores)Over 2 weeks

TNSS is the sum of the four symptom scores of runny nose, nasal congestion, nasal itching, and sneezing, with each symptom scoring from 0 to 3. The total score is 12, the higher the score, the worse the symptoms.

Secondary Outcome Measures
NameTimeMethod
Adverse events (AEs)up to 12 weeks

Incidence of AEs.

Change from Baseline in rTNSSOver 4 weeks

TNSS is the sum of the four symptom scores of runny nose, nasal congestion, nasal itching, and sneezing, with each symptom scoring from 0 to 3. The total score is 12, the higher the score, the worse the symptoms.

Change from baseline in RQLQ(Rhinoconjunctivitis Quality of Life Questionnaire) scoresweek2、4

The RQLQ is used to measure the problems that adults with rhinoconjunctivitis experience in their daily lives. It has 28 questions in 7 domains. The total score is the sum of the 7 domain scores, with higher scores being associated with poorer quality of life.

Mean change from baseline in iTOSS(instantaneous total ocular symptom scores)week 2、4

TOSS is the sum of symptom scores of eye itching/foreign body sensation/redness and tearing, with each symptom scoring from 0 to 3. The total score is 6, the higher the score, the worse the symptoms.

Change from Baseline in rTOSS( reflective total ocular symptom scores)Over 2、4 weeks

TOSS is the sum of symptom scores of eye itching/foreign body sensation/redness and tearing, with each symptom scoring from 0 to 3. The total score is 6, the higher the score, the worse the symptoms.

Mean change from baseline in iTNSS(instantaneous total nasal symptom scores)week 2、4

TNSS is the sum of the four symptom scores of runny nose, nasal congestion, nasal itching, and sneezing, with each symptom scoring from 0 to 3. The total score is 12, the higher the score, the worse the symptoms.

Change from baseline in VAS(Visual Analog Scale) scoreweek2、4

Patients marked the score corresponding to the severity of the current overall AR symptoms by drawing a line on a 0-10 cm scale,the higher the score, the worse the symptoms.

Immunogenicity characteristicsup to 12 weeks

Positive rate of ADA(anti-drug antibody) testing
