IgE Antibody-inducing peptide (FPP004X)

Antibody-inducing peptide FPP004X is a compound targeting immunoglobulin E (IgE) developed upon joint research with Osaka University. We are currently conducting preclinical studies with the compound on pollinosis.
IgE is an important molecule involved in the development and progression of allergic diseases. Pollinosis, an allergic disease, exhibits seasonal allergic rhinitis against allergens such as cedar pollen, and its main symptoms include sneezing, mucosa and nasal obstruction.
FPP004X, an antibody-inducing peptide against the target protein IgE, is expected to have a sustained effect on pollinosis because it causes immune cells in the body to produce antibodies against IgE for a sustained period. Due to the long-lasting effect of the vaccine, we will continue the development of FPP004X with the aim of providing patients with a new, highly convenient treatment option that can relieve symptoms throughout the pollinosis season (the period of pollen scattering) if administered prior to the start of the season.
