Bayer Healthcare AG Spin-out, Actimis Pharmaceuticals, Completes $6 Million Series A Financing


San Diego, CA, April 28, 2005 - Actimis Pharmaceuticals, Inc., a startup company dedicated to developing and commercializing small molecule therapeutics for respiratory and inflammatory diseases, today announced a $6 million private placement of its Series A stock. The financing was led by Sanderling Ventures of San Mateo, California. Additional investors include Mitsui & Co. Venture Partners of New York.

Bayer Healthcare AG has assigned the rights to five preclinical research programs to Actimis, including two advanced programs with highly optimized lead candidates and three additional research-stage programs. The majority of the targets represent first-in-class molecules and have broad application across respiratory diseases including asthma and chronic obstructive pulmonary disease (COPD) as well as inflammatory disorders including atopic dermatitis, rheumatoid arthritis, psoriasis and others. Financial terms of the transaction were not disclosed.

"Our validated targets and proprietary programs are well ositioned to produce novel therapeutics that address critical unmet medical needs," said Kevin B. Bacon, Ph.D., founder and chief scientific officer of Actimis. "We are now setting up state-of-the-art laboratory facilities and looking to establish Actimis as a leading force in drug development for respiratory and inflammatory diseases, and we hope to file an investigational new drug application (IND) with the FDA in the near future."

"Actimis' research programs have been developed to an advanced stage using very high standards for both biological validation and medicinal chemistry. The company's work in chemokines and chemoattractants, which are an emerging new area of discovery and are the focus of the most advanced programs in Actimis' portfolio, has a high potential for therapeutic intervention," said Peter C. M. McWilliams, Ph.D., principal with Sanderling Ventures and chairman of Actimis. "We look forward to working with Actimis to rapidly advance these exciting programs to the clinic."
