简要总结
To evaluate TQH2722 injection in all patients receiving background treatment with mometasone furoate nasal spray (MFNS) and loratadine. The efficacy, safety and immunogenicity of the solution in patients with seasonal allergic rhinitis compared with placebo are expected to include 168 patients with confirmed seasonal allergic rhinitis (SAR) who have failed to respond to standard treatments.
