NEW HAVEN, Conn.--(BUSINESS WIRE)--Kolltan Pharmaceuticals, Inc. announced today that the Company has raised over $35 million in its Series A preferred stock financing. Kolltan is a next-generation oncology therapeutics company applying expertise in novel receptor tyrosine kinase (RTK) targets based on recent discoveries in the laboratory of Dr. Joseph Schlessinger, William H. Prusoff Professor and Chairman of the Department of Pharmacology at Yale University School of Medicine. The proceeds of the Series A financing will be used to advance Kolltan’s therapeutic development pipeline.
Kolltan also reported in a separate press announcement today expansion of the Company’s senior management team with the appointments of Michael Schmertzler as Chief Executive Officer and Director, and Yaron Hadari, Ph.D., as Vice President of Research.
Mr. Schmertzler and Arthur Altschul, Co-Founder and Chairman of the Kolltan Board, commented, "We are proud to announce the closing of this financing with an excellent group of experienced investors, including Purdue Pharma, L.P., HBM Capital Partners, the Pritzker/Vlock family, as well as other substantial private life science investors. We look forward to working with them to develop and commercialize Dr. Joseph Schlessinger’s important discoveries licensed from Yale University by Kolltan.”
E. Jonathan Soderstrom, Managing Director, Yale University Office of Cooperative Research, stated, “We are excited to work with the Kolltan team to translate Dr. Schlessinger’s discoveries into important new therapeutics for treating life-threatening diseases.”
Dr. Schlessinger is Co-Founder, Chief Scientist and a Director of Kolltan. He is also Co-Founder and Chairman of Plexxikon and in 1991 co-founded SUGEN which developed an RTK oncology therapeutic now marketed by Pfizer. Prior to joining Yale, from 1998-2001, Dr. Schlessinger was the Director of the Skirball Institute for Biomolecular Medicine at New York University (NYU) Medical Center and, from 1990-2001, the Milton and Helen Kimmelman Professor and Chairman of the Department of Pharmacology at NYU Medical School. Dr. Schlessinger has received many prizes and awards and is a member of the National Academy of Sciences and the Institute of Medicine of the National Academies, among other organizations.
Dr. Schlessinger stated, “We have formed Kolltan to translate important new insights concerning the mechanism of RTK-related disease into therapeutics that address the limitations of first generation drugs now in the clinic. We expect Kolltan to build on the advanced research that we have completed and move expeditiously toward the development of products and clinical trials.”
