Leadiant Biosciences, Inc. is a pharmaceutical company focused on the research and development of therapies to help improve the lives of people around the world who suffer from specific diseases.

We are driven to provide excellence and innovation, because we understand that patients, many of whom have no other treatment options, depend on us for their well-being. This is why the study of rare diseases is an integral part of our research activity and heritage in orphan drug development. In 1984, we became only the fourth company in the world to receive an Orphan Drug Designation in the United States, and since then, we have obtained seven more.

We continue to honor this legacy with our commitment to patients by advancing a diverse pipeline. Our innovative research programs and development of novel product candidates are led by our scientists in partnership with a wide range of physicians, researchers and leading academic and biotechnology organizations around the world.
