About KaloBios' Lead Product Candidates

KaloBios has three antibody products now in clinical development.

KB001 -- a HumaneeredT, high-affinity antibody fragment that KaloBios is developing for the treatment of Pseudomonas aeruginosa infections. The antibody is currently in Phase 1/2 testing in both patients with cystic fibrosis and intensive care patients on ventilation.
KB002 -- a monoclonal antibody that has completed five clinical trials as a treatment for autoimmune diseases, including persistent asthma and rheumatoid arthritis. KB002 is a prototype for KB003, a HumaneeredT IgG1 antibody that has finished Phase 1 clinical trials and will start Phase 2b clinical trials in 2009.
KB004 -- a HumaneeredT IgG1 antibody that binds to a receptor tyrosine kinase expressed on the surface of tumor vasculature and tumor cells. This antibody is being developed for the treatment of solid tumors and some hematologic cancers.

The company plans to offer all three programs (KB001, KB002/003 and KB004) for partnering in 2009.
