KaloBios Raises $20 Million in Series C Financing

KaloBios Pharmaceuticals, Inc., a privately held biopharmaceutical company, recently announced the completion of a Series C venture financing of $20 million. Lehman Brothers led the round, which also included the participation of previous investors MPM Capital, Sofinnova Ventures, Alloy Ventures, GBS Venture Partners, 5AM Ventures, Singapore Bioinnovations Pte., and Lotus BioScience Ventures. Proceeds from the financing will be used to advance clinical development of the company’s two therapeutic antibody candidates, KB001 and KB002.

“We are very pleased to complete this significant financing,” said David Pritchard, the company’s chief executive officer, “which in addition to the major Humaneering™ partnership that we announced in April 2007, further extends KaloBios’ financial resources into 2009. We expect these new funds to support the development of our two lead product candidates, KB001 and KB002 into Phase 2 development, as well as the advancement of a third therapeutic program into clinical trials.”

KaloBios has an ongoing clinical program for KB002 in rheumatoid arthritis. The company also recently initiated Phase 1 studies of KB001, which will be investigated for the treatment of Pseudomonas aeruginosa infections.

“We were attracted to the KaloBios investment opportunity by the combination of the antibody technology platform, the two attractive programs in the clinic, and the experienced management team,” said Jeffrey Ferrell, Senior Vice President of Lehman Brothers. “Given the high demand for antibody programs and technologies in the partnering and merger and acquisition markets, we think KaloBios is well positioned.”
