KaloBios Provides Clinical Update and Reports Second Quarter Financial Results

SOUTH SAN FRANCISCO, Calif., Aug. 7, 2014 /PRNewswire/ -- KaloBios Pharmaceuticals, Inc. (Nasdaq: KBIO) today provided an update on its current clinical programs and announced financial results for the second quarter of 2014.

Development Program Updates
KaloBios completed enrollment in July in the open-label Phase 1 dose escalation study of KB004 in hematologic malignancies. This study has enrolled a total of 50 patients in the Phase 1 portion of the study, including patients with myelodysplastic syndrome (MDS), myelofibrosis (MF) and acute myeloid leukemia (AML), with 80% of patients enrolled being late-stage AML patients. The drug continues to be well tolerated with the most commonly reported side effects being first-dose infusion reactions. No maximum tolerated dose (MTD) was reached in this study. Based on the outcome of the Phase 1 portion of the study, KaloBios has declared 250mg as the high dose for purposes of the Phase 2 expansion portion of the study.

The Phase 2 expansion portion of the study will be enrolling patients with hematologic malignancies that are pre-screened to be EphA3 positive. Now that the high-dose has been declared, KaloBios will seek to enroll one high-dose cohort of 10 MDS patients, a second high-dose cohort of 10 AML patients, and a third high-dose cohort comprised of 10 MF patients.KB001-A
In July, KaloBios announced that target enrollment in the Phase 2 study in cystic fibrosis (CF) patients with chronic Pseudomonas aeruginosa (Pa) lung infections was achieved with the enrollment of the 180th patient. KaloBios expects to release top-line data on this study early in the first quarter of 2015.

KaloBios also at that time announced that it had regained full global rights to KB001-A in all indications as a result of the execution of a negotiated termination of the company's collaboration agreement with Sanofi Pasteur. KaloBios has stated that it intends to seek a partner with a focus on infectious disease, hospital pharmaceuticals, or cystic fibrosis who can accelerate and financially support the future development of KB001-A."We are very excited about the recent progress we have made on our programs," said Nestor A. Molfino, MD, MSc, Chief Medical Officer of KaloBios. "Completing enrollment in our Phase 2 KB001-A study in CF patients in a timeframe that will potentially allow us to report out top-line data in early 2015 was a major achievement for the company. At the same time, completing enrollment in the KB004 Phase 1 dose escalation study sets the stage for us to initiate enrollment in the high-dose cohorts in the Phase 2 efficacy-seeking portion of our KB004 study in the second half of 2014."

Top line KB001-A CF Phase 2 study resultsSecond Quarter 2014 Financial Results
Net loss for the three months ended June 30, 2014 was $9.8 million or $0.30 per common share, as compared to $11.8 million or $0.49 per common share for the same period in 2013. 

No contract revenue was reported for the second quarter of 2014 as compared to $15,000 reported in the same period in 2013. The decrease in contract revenues was due to the completion of all substantive performance obligations related to research support activities under our agreement with Sanofi Pasteur.

Research and development (R&D) expenses were $6.7 million for the three months ended June 30, 2014 as compared to $9.6 million for the same period in 2013. The decrease in R&D expense was primarily due to decreased clinical trial activity compared with the prior period largely as a result of the completion of the KB003 Phase 2 study in patients with severe asthma in the first quarter of 2014. General and administrative (G&A) expenses were $2.8 million for the second quarter of 2014 compared to $1.9 million for the same period in 2013. The increase in G&A expenses was due primarily to costs incurred in our move into a new facility in the second quarter of 2014 as well as higher legal, accounting and consulting costs associated with becoming a public reporting company.

As of June 30, 2014, KaloBios had cash, cash equivalents and investments totaling $59.2 million, compared to $76.7 million at December 31, 2013.

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 advanced three programs to clinical development:

  • KB001-A is an anti-PcrV mAb fragment being developed for the prevention and treatment of Pseudomonas aeruginosa (Pa) infection. KaloBios is conducting a 180 patient Phase 2 study in cystic fibrosis (CF) subjects with chronic Pa lung infection. KaloBios has received Orphan Drug designation from both the U.S. FDA and the European Medicines Agency for KB001-A for the treatment of Pa lung infection in CF patients. KB001-A has also received Fast Track Status from the U.S. FDA for the prevention of ventilator associated pneumonia. KaloBios is planning to seek a partner to help accelerate the development of this program.
  • KB004 is an anti-EphA3 mAb with potential in treating hematologic malignancies and solid tumors. KaloBios is running an ongoing Phase 1/2 study evaluating KB004 in hematologic malignancies. The Phase 1 dose escalation portion of that study in subjects with hematologic malignancies is fully enrolled with dosing ongoing. KaloBios initiated the Phase 2 expansion portion of the study focused on patients with certain EphA3 positive hematologic malignancies in 2014.
  • KB003 is an anti-GM-CSF mAb with potential to treat inflammatory diseases that was being developed for the treatment of severe asthma. In early 2014, KaloBios completed a Phase 2 clinical study in 160 patients with severe asthma which did not meet its primary endpoint of improvement in FEV1 from baseline as compared to placebo. As a result, KaloBios discontinued development of this compound in severe asthma, and is continuing to analyze the Phase 2 data to review with thought leaders. KaloBios is currently evaluating other possible indications in order to determine next steps, if any, in the development of KB003.
  • 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.
