South San Francisco, CA (September 6, 2012):  KaloBios Pharmaceuticals, Inc. today announced that the company has completed a $10 million long-term debt financing with MidCap Financial SBIC, LP, with an option to borrow an additional $5 million by the end of the second quarter of 2013. The company also noted that, during the second quarter of 2012, it had closed a Series E Preferred Stock financing predominately to new institutional investors, raising gross proceeds of $20.25 million. Proceeds from the transactions will be used to advance the clinical development of the company’s proprietary patient-targeted monoclonal antibody therapeutics and for general corporate purposes.

“These new funds totaling up to approximately $35 million in gross proceeds will support Phase 2 clinical trials for KB003, our drug candidate for severe asthma, and KB001-A, our drug candidate for cystic fibrosis (CF) patients who are chronically infected with Pseudomonas aeruginosa (Pa); and a Phase 1 clinical trial for KB004, an anti-EphA3 mAb that has the potential to treat hematologic malignancies and solid tumors. These proceeds will also give us the financial flexibility to execute on our corporate plans,” said Jeffrey H. Cooper, KaloBios’ Chief Financial Officer.

About KaloBios

KaloBios Pharmaceuticals, Inc. is developing a portfolio of proprietary, patient-targeted, first-in-class monoclonal antibodies (mAbs) designed to significantly improve the lives of seriously ill patients with difficult-to-treat diseases.

Currently, KaloBios has three drug development programs:

·         KB001-A, an anti-PcrV mAb fragment, is partnered with Sanofi Pasteur and is being developed for the treatment and prevention of Pa infection. KaloBios has retained rights for the cystic fibrosis indication and plans to initiate a Phase 2 study in CF subjects with chronic Pa infection.

·         KB003, an anti-GM-CSF mAb with potential to treat inflammatory diseases is being developed for the treatment of severe asthma. KaloBios is initiating a Phase 2 study in asthma uncontrolled by corticosteroids in the third quarter of 2012.

·         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 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 with 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.
