Traversa Raises $2M to Advance RNAi Delivery in Angel-Led Series A Financing

LA JOLLA, Calif.  February 04, 2008 - Traversa Therapeutics, Inc. a privately held developer of RNAi delivery technologies, announced today the completion of a $2 million Series A financing led by the San Diego Tech Coast Angels and joined by investors Mesa Verde Venture Partners and Morningside Group.

Traversa was founded with technology developed by Professor Steven F. Dowdy, Ph.D., and his research group at the Howard Hughes Medical Institute and the University of California San Diego (UCSD) relating to siRNA delivery and the induction of RNA Interference (RNAi).

"There is a great need for novel short interfering RNA (siRNA) delivery platforms. This technology has shown outstanding delivery characteristics in pre-clinical models, as well as in vitro delivery to nearly all cell types and entire cell populations assayed in a non-cytotoxic fashion. These cell types include primary cells, T cells, B cells, Macrophage, huESC and tumor cells, where other delivery approaches have failed,” noted Dr. Dowdy, co-founder of Traversa.

"We are very pleased with the impact that our investors have already made in developing new opportunities for the Company," said Hans A. Petersen, President and CEO of Traversa. "The technology has received an outstanding level of interest for use with human therapeutics, and as a high throughput screening reagent, providing the Company with both long-term growth prospects and a short-term revenue stream to augment this financing. Traversa is currently being evaluated by several large pharmaceutical companies to treat diseases of the eye and nose, metabolic diseases, cancer and infectious diseases."
