About KaloBios

KaloBios Pharmaceuticals, Inc. is developing a portfolio of proprietary, patient-targeted, first-in-class monoclonal antibodies (mAbs) designed to treat serious life-threatening or debilitating disease for which there is an unmet medical need with a clinical focus on serious respiratory diseases and cancer.

Currently, KaloBios has three drug development programs:

·         KB003, an anti-GM-CSF mAb with potential to treat inflammatory diseases, is being developed for the treatment of severe asthma and is currently enrolling patients in a 150 patient Phase 2 study in the United States, Europe and Australia.
·         KB001-A, an anti-PcrV mAb fragment, is partnered exclusively with Sanofi and is being developed for the prevention and treatment of Pseudomonas aeruginosa (Pa) infection. KaloBios has retained rights for the cystic fibrosis (CF) indication and has initiated a 180 patient Phase 2 study in CF subjects with chronic Pa infection in the United States. Sanofi is pursuing a ventilator associated pneumonia prevention indication in the intensive care setting, an indication which has received U.S. FDA Fast Track Designation.
·         KB004, an anti-EphA3 mAb, has potential in treating hematologic malignancies and solid tumors. KaloBios is currently testing this drug in a Phase 1 study in subjects with hematologic malignancies.

All of the company's antibodies were generated using its proprietary Humaneered® technology, a method that converts nonhuman antibodies (typically mouse) into recombinant antibodies that have a high binding affinity to their target and are designed for chronic therapeutic use. The company believes that antibodies produced using its Humaneered® technology offer important clinical and economic advantages over antibodies generated by other methods in terms of high binding affinity, high manufacturing yields, and minimal to no immunogenicity (inappropriate immune response) upon repeat administration in humans.
