BOULDER -- Crestone, Inc. today announced a contract award from the National Institutes of Health for the advancement of its antibiotic candidate CRS0540 to treat infections caused by drug-resistant Gram-positive bacteria.Crestone-logo 

CRS0540 has demonstrated efficacy in several mouse models of infection including MRSA soft tissue and blood stream infections, pneumococcal lung infection, and even an inhalational anthrax challenge model, the company said.

Under this four-year contract from NIH, Crestone’s drug candidate CRS0540 will be manufactured under GMP conditions, formulated for oral and intravenous administration, tested in IND-enabling safety pharmacology and GLP toxicity studies, and evaluated for safety in a first-in-human Phase 1 clinical trial.

Potential indications are skin and skin structure and respiratory infections.

“Antibiotics with a novel mode of action and a good safety profile are sorely needed to augment the armamentarium of drugs to treat infections with resistant pathogens, and CRS0540 dosed orally has already demonstrated efficacy in various animal models of infection,” said Urs Ochsner, co-founder and VP of R&D and CEO at Crestone.

“Medicinal chemistry efforts over several years to improve potency and to optimize the pharmacological properties of these DNA replication inhibitors have led to CRS0540, a very promising candidate to move into clinical development,” said Joshua Day, director of chemistry at Crestone, who will be the principal investigator.

Funding for these studies will be provided entirely by NIH’s National Institute of Allergy and Infectious Diseases (NIAID) under Contract No. 75N93020C00020 for a total of up to $18.2 million, including the base period and subsequent option periods.
