Leading the way in corneal therapy

Claris works to improve lives by uniting unmet needs in ophthalmology with robust science and data-driven decision making

Our Story

Scientific cofounders, Dr. Reza Dana, MD, MSc, MPH and Dr. Sunil Chauhan, DVM, PhD, and Founding CEO Clarke Atwell, MIB, launched Claris Biotherapeutics, licensing intellectual property from Massachusetts Eye and Ear Infirmary (MEEI) and accessing drug substance in an agreement with partner Kringle Pharma.

The foundational intellectual property for Claris was based on the scientific work of Dr. Dana and Dr. Chauhan at the MEEI. From their research on mesenchymal stem cells at MEEI, they identified the potential therapeutic benefits of hepatocyte growth factor (HGF) in multiple in vitro, in vivo, and ex vivo models. Claris Bio has replicated these findings through an independent, third-party laboratory.

Claris’ lead program brings a topical ocular biologic solution of dHGF, a molecule with the potential to restore structural and functional corneal integrity, to eyes with Limbal Stem Cell Deficiency (LCSD).

Sunil chauhan

Sunil Chauhan, DVM, PhD

CO-FOUNDER AND SCIENTIFIC ADVISOR

Dr. Chauhan is an Associate Professor in the Harvard Medical School Department of Ophthalmology, with a scientist appointment at Massachusetts Eye and Ear and an affiliated faculty at the Harvard Stem Cell Institute. Working at the intersection of immunology, stem cell biology, and regenerative medicine, Dr. Chauhan's research for the past 20 years has focused on determining the functions of different immune and non-immune cells in promoting immune quiescence and tissue regeneration. His research helped establish that mesenchymal stem cells (MSC) promote tissue regeneration by secreting high levels of hepatocyte growth factor (HGF), suggesting a novel HGF-based approach that could potentially eliminate the need for cell-based and conventional therapies for ocular diseases. Dr. Chauhan's research program is funded by several NEI/NIH and Department of Defense grants and awards. He has published over 120 papers, patents, and applications, which have led to multiple licenses to biotech companies.
