About KaloBios
KaloBios Pharmaceuticals, Inc. is seeking to improve the lives of patients by developing innovative therapies to treat diseases of high unmet medical need, with a focus on oncology. KaloBios has focused on advancing the following immuno-oncology and oncology programs in clinical development:

• KB004 is a non-fucosylated mAb targeting EphA3 with the potential to treat hematologic malignancies and solid tumors. KB004 is designed to kill tumor cells through multiple mechanisms, including antibody-directed cellular cytotoxicity (ADCC), direct apoptosis or disruption of the tumor stem cell environment and the vasculature that feeds it.
• KB003, or lenzilumab, is an anti-GM-CSF mAb that KaloBios is evaluating in oncology indications where GM-CSF may play a key role, such as chronic myelomonocytic leukemia (CMML). The IND for KB003 in CMML, an orphan oncology indication, has been cleared by the FDA.

All of the company's antibodies were generated using its proprietary Humaneered® technology, a method that converts non-human antibodies (typically mouse) into recombinant antibodies that have a high binding affinity to their target and are designed for chronic therapeutic use.
