About KaloBios

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

Currently, KaloBios has three drug development programs:

  oKB003, an anti-GM-CSF mAb with potential to treat inflammatory diseases,
    is being developed for the treatment of severe asthma. Enrollment of 160
    patients has been completed in a planned 150 patient Phase 2 study in the
    United States, Europe and Australia.
  oKB001-A, an anti-PcrV mAb fragment, is partnered exclusively with Sanofi
    and is being developed for the prevention and treatment of Pa infection.
    KaloBios has retained rights for the CF indication and has initiated a 180
    patient Phase 2 study in CF subjects with chronic Pa lung 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.
  oKB004, 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.
