Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this study was to evaluate the efficacy, safety, and dose-response of ASP4070 vaccinated in patients with cedar pollinosis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Subjects were vaccinated with ASP4070 or placebo at 2 week intervals. Clinical symptoms were evaluated after cedar pollen exposure in a chamber at 4, 8 and 12 weeks after the last vaccination to identify the timing of the onset of therapeutic effect.
