About Rib-X Pharmaceuticals, Inc.
Rib-X Pharmaceuticals, Inc. is a product-driven small molecule drug discovery
and development company focused on the structure-based design of new classes
of antibiotics. The Company's underlying drug discovery engine capitalizes on
its proprietary high-resolution crystal structure of the ribosome, which
performs an essential role in protein synthesis. Many known, commercially
valuable antibiotics exert their effects by binding to the bacterial ribosome.
The Company's integrated research strategy, which combines state-of-the-art,
proprietary computational analysis, X-ray crystallography, medicinal
chemistry, microbiology and biochemistry, allows it to rapidly synthesize new
agents designed to avoid typical antibiotic resistance mechanisms. Rib-X's
iterative intelligent engine has yielded several distinctive new antibiotics
that can be used for the treatment of either community- or hospital-acquired
infections. In addition to Rx-04, Rib-X has successfully completed Phase 2
trials with delafloxacin (RX-3341), a broad spectrum fluoroquinolone with
potent activity against quinolone resistant Gram-positive bacteria including
MRSA. Radezolid (RX-1741), an oxazolidinone that was discovered at Rib-X, as
an oral/IV agent for treatment of serious Gram-positive infections has
completed two Phase 2 trials and the Rx-02 discovery program which is focused
on developing an IV/oral macrolide active against methicillin-resistant S.
aureus, multidrug-resistant Streptococcus pneumoniae and S. pyogenes. Both
delafloxacin and radezolid are currently in late stage clinical trials.
