Is this trial a fit for you?

Likely a good fit

People with seasonal allergic rhinitis whose symptoms remain uncontrolled despite usual treatments and who can attend study visits at Beijing Tongren Hospital are the intended participants.

Probably not a fit

People with well‑controlled allergy symptoms, perennial or non‑allergic rhinitis, or those unable to travel to the Beijing site are unlikely to receive benefit from this trial.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a Phase 2 interventional trial testing CM310, a monoclonal antibody that targets the interleukin‑4 receptor, in patients with uncontrolled seasonal allergic rhinitis. Participants will receive CM310 or a placebo and be followed for changes in nasal and ocular symptoms as well as safety measures. The trial is conducted at Beijing Tongren Hospital with voluntary informed consent and standard exclusion criteria to protect participant safety. Findings will help determine whether CM310 reduces symptom burden and improves quality of life compared with placebo.

Why it matters

Potential benefit: If successful, CM310 could reduce nasal and eye allergy symptoms and improve daily functioning for people with uncontrolled seasonal allergic rhinitis.

How similar studies have gone: Other drugs that block the IL‑4/IL‑13 pathway have shown benefit in related allergic conditions, offering a supportive rationale though CM310 itself is a newer agent with limited prior data.
