Efficacy and Safety of PQ Grass in Subjects With Seasonal Allergic Rhinitis and/or Rhinoconjunctivitis Induced by Grass Pollen

Seasonal Allergic Rhinitis Clinical Trial

Official title:
A Randomised, Double-blind, Placebo-controlled Clinical Trial to Evaluate the Efficacy and Safety of PQ Grass in Subjects With Seasonal Allergic Rhinitis and/or Rhinoconjunctivitis Induced by Grass Pollen Exposure

Clinical Trial Summary

The PQGrass306 (G306) clinical trial is the pivotal Phase III efficacy clinical trial of PQ Grass. The aim of the G306 pivotal clinical trial is to confirm the efficacy and safety of the optimal effective dose of PQ Grass 27600 SU. This will be determined through the measurements of the effect of PQ Grass on the symptoms of seasonal allergic rhinitis (SAR)/rhinoconjunctivitis and the use of relief medications to control these symptoms during the peak grass pollen season (GPS).

Clinical Trial Description

Multi-centre, randomised, parallel group, double-blind, placebo-controlled clinical trial to confirm the efficacy and safety of the optimal effective dose of PQ Grass (27600 SU). Randomized study subjects, in a randomisation ratio of 1:1, will receive either treatment with 6 injections of active treatment (900, 2700, 6000, 6000, 6000 and 6000 SU sequentially) to achieve a cumulative nominal dose of 27600 SU, or 6 injections of placebo prior to the onset of the grass pollen season (GPS). The aim of the study is to confirm the efficacy and safety of the optimal effective dose of the PQ Grass 27600 SU dose. Efficacy will be determined through the measurements of the effect of PQ Grass on the symptoms of seasonal allergic rhinitis (SAR)/rhinoconjunctivitis and the use of relief medications to control these symptoms during the peak GPS. ;
