Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The main questions it aims to answer are:
Does drug CM310 relieve the symptoms of participants? What medical problems do participants have when injecting CM310? Researchers will compare CM310 to a placebo (a look-alike substance that contains no drug) to see if CM310 works to treat NARES.
Participants will:
Inject CM310 or a placebo every 2 weeks for 12 weeks, and follow up for another 8 weeks.
Visit the clinic once every 2 weeks for checkups and tests. Keep a diary of their symptoms every day.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Adult NARES patients with an inadequate response to mometasone furoate nasal spray will be enrolled. While continuing treatment with intranasal mometasone furoate, patients will be randomized to receive either Stapokibart or a placebo. Over the 12-week treatment period and the subsequent 8-week follow-up period, the alleviation of nasal and ocular symptoms, the incidence of adverse events, and the results of safety assessments (such as physical examinations, electrocardiograms, complete blood counts, and blood biochemistry) will be evaluated. The final aim is to assess the efficacy and safety of Stapokibart in treating patients with NARES.

The subject's history prior to the screening period indicates inadequate control of NARES symptoms (with an iTNSS ≥4 and at least one of the symptoms - nasal congestion, rhinorrhea, nasal itching, or sneezing - scoring ≥2) despite the use of intranasal corticosteroids or other medications (e.g., antihistamines, leukotriene receptor antagonists) following symptom onset.
6. At the baseline visit (after run-in treatment), the subject must meet the following criteria: an iTNSS ≥4, the average of the most recent 6 daily Reflective Total Nasal Symptom Scores (rTNSS) ≥4, and at least one of the symptoms - nasal congestion, rhinorrhea, nasal itching, or sneezing - scoring ≥2 in these assessments (i.e., the 3 morning and 3 evening evaluations over the last three 24-hour periods, including the iTNSS assessment at the baseline visit).
7. Willing and able to comply with all visits, study-related procedures, and questionnaires, including adherence to required background medications and completion of a daily electronic diary (eDiary). During the screening/run-in period, subjects must complete at least 80% of the diary assessments.
