About Paratek

Paratek is a biopharmaceutical company focused on the development and commercialization of innovative antibiotics. Paratek's lead product candidate, omadacycline, is a novel tetracycline-derived, broad-spectrum antibiotic being developed in both oral tablet and intravenous formulations for use as a first-line monotherapy antibiotic for ABSSSI, CABP, urinary tract infections (UTI) and other serious community-acquired bacterial infections, particularly when antibiotic resistance is of concern to prescribing physicians. Omadacycline has received Qualified Infectious Disease Product (QIDP) designation by the U.S. Food and Drug Administration for both the oral and intravenous formulations in all three of these infectious disease categories. Omadacycline has Special Protocol Assessment agreements with the U.S. Food and Drug Administration for the phase 3 trials planned in ABSSSI and CABP.

Paratek's second product candidate, WC 3035, is a novel tetracycline-derived compound, with dual narrow-spectrum antibacterial and potent anti-inflammatory activity, for the treatment of acne and rosacea in the community setting. Paratek has licensed rights to WC 3035 for the treatment of acne and rosacea in the United States to a subsidiary of Actavis (formerly Warner Chilcott), while retaining rights in the rest of the world. Actavis is responsible for the clinical development of WC 3035 for the treatment of acne in the United States. A phase 3 program in moderate-severe acne is expected to be initiated in the second half of 2014 for WC 3035.

About Transcept

Transcept Pharmaceuticals, Inc. is a specialty pharmaceutical company focused on the development and commercialization of proprietary products that address important therapeutic needs in the field of neuroscience.
