CRS0540 Gram-positives Overview
We are developing a novel class of small molecule antibiotics targeting PolC, the replicative DNA polymerase in Gram-positive bacteria. By inhibiting a novel bacterial target, these compounds circumvent existing mechanisms of antibiotic resistance. CRS0540 exhibits broad spectrum activity against all clinically significant Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA), penicillin-resistant Streptococcus pneumoniae (PRSP), Streptococcus pyogenes (Group A strep), Streptococcus agalactiae (Group B strep), vancomycin-resistant Enterococci (VRE), Bacillus anthracis (anthrax), and Listeria monocytogenes.
Key Areas of Study
- Novel mechanism of action based on inhibition of PolC, an essential DNA polymerase
- Oral bioavailability, facilitating outpatient treatment
- Bactericidal activity
- Low spontaneous resistance rates
- In vivo efficacy in preclinical models of infection
- Low propensity for toxicity observed in vitro and in vivo
Ongoing CRS0540 Gram-positives Studies
Novel antibacterial candidate CRS0540 is still in pre-clinical development, so no clinical studies are available for this drug candidate at the moment. If you’d like to help further our research into novel antibacterial drugs, you may be interested in joining our phase 2 clinical study on CRS3123 for C. difficile. Another project in our pipeline, CRS3123 is a drug being developed to treat a devastating GI tract infection. Learn more about our ongoing clinical study below.
