Brief Summary

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

This is a research study intending to look at the response of a specific type of allergy cells in the blood (called T cells) to a a type of immunotherapy product known as SPIREs (Synthetic Peptide Immuno-Regulatory Epitopes), across a broad range of subjects. This is a non-interventional study in which no investigational product will be administered to any subject.
