BRISBANE, Calif., April 06, 2017 (GLOBE NEWSWIRE) -- KaloBios Pharmaceuticals, Inc. (OTC:KBIO), a biopharmaceutical company focused on advancing medicines for patients with neglected and rare diseases, today provided an update on the company’s progress advancing its lead program benznidazole for the treatment of Chagas disease, a neglected tropical disease.

“We continue to execute on our internal deadlines and remain on track for the advancement of benznidazole for the significant unmet need of Chagas disease here in the U.S.,” said Cameron Durrant, MD, chairman and CEO, who today is also taking part in the International Society for Neglected Tropical Diseases (ISNTD) Chagas conference in Washington, D.C.

The company has made significant progress advancing its development plan for benznidazole as a potential U.S. treatment for Chagas disease, including:

  • Regulatory: The company is on track to submit its IND with the Food and Drug Administration (FDA) in May 2017. Future meetings with the FDA are expected to provide further refinement of the development plan.
  • Manufacturing: Batches of the drug are complete and prototype tablets have been made. The company is on schedule for the delivery of final tablets. Work is also underway to develop efficiencies and begin scale-up for manufacturing processes.
  • Clinical Data: The company has secured safety and efficacy databases necessary for its regulatory dossier. In January 2017, the FDA confirmed the acceptability of a 505(b)(2) development pathway using data drawn from previously conducted studies.

About Benznidazole

Benznidazole is an oral anti-parasitic medication used in the treatment of Chagas disease, caused by a protozoan parasite Trypanosoma cruzi carried and transmitted by triatomine insects (often called "kissing bugs"). According to the Centers for Disease Control and Prevention (CDC), an estimated 300,000 people in the United States are infected with Chagas disease, which, if left untreated, can lead to serious and potentially life-threatening cardiovascular, gastro-intestinal and neurological complications. Benznidazole is the current preferred treatment for Chagas disease in other parts of the world but is not currently approved by the FDA in the U.S. Legislation is in place to incentivize companies to bring treatments to the U.S. market for certain neglected tropical diseases, including Chagas. If approved, benznidazole could be eligible to receive a priority review voucher.
