At IgGenix, our mission is to develop first-in-class therapies for millions of people whose daily lives are limited by allergies. We believe we can truly change the face of allergic disease, empowering people to live life without the constant fear of a life-threatening allergic reaction.

At the intersection of biotechnology and allergy, our team begins with a deep understanding of molecular immunology thanks to our SEQ SIFTER™ antibody discovery platform. We then leverage this unique understanding to develop products intended to provide faster and more sustained clinical responses. Our first lead development candidate in food allergy, a first-in-class antibody, takes a revolutionary approach to directly address allergic disease by blocking the allergic cascade.

The IgGenix Platform

Our single cell RNA-sequencing-based discovery platform, SEQ SIFTER™, captures extremely rare human B cells that produce IgE antibodies directly from human blood. Through our unique technology, IgGenix isolates and re- engineers fully human, high affinity, allergen-specific IgG antibodies designed to block and prevent the allergic cascade. By targeting common immunodominant allergens and their most immunodominant epitopes across the patient population, we intend to treat allergic pediatric and adult patients alike.

IgGenix is currently conducting research as part of an Institutional Review Board-approved observational study to create allergy therapeutics. IgGenix has discovered IgE antibodies and is conducting research across allergic diseases.

Several programs are currently in the IgGenix pipeline targeting both food and environmental allergies. Additional platform opportunities exist in other disease areas in which IgE and/or rare cells play an important role.
