About Paratek Pharmaceuticals

Paratek Pharmaceuticals, Inc. is engaged in the discovery and commercialization of new therapeutics that treat serious and life-threatening diseases, with a particular focus on the growing worldwide problem of antibiotic resistance. Paratek is advancing novel compounds that can circumvent or block bacterial resistance. Paratek’s lead compound, PTK 0796, is a broad-spectrum antibiotic derived from the tetracycline class with oral and IV formulations that is being developed for the treatment of the most common and serious hospital bacterial infections, including those caused by resistant strains such as MRSA (methicillin-resistant Staphylococcus aureus) and MDRSP (multi-drug resistant Streptococcus pneumoniae). Oral and IV formulations of PTK 0796 were compared to Zyvox ® in a Phase 2 clinical study in complicated skin and skin structure infections (cSSSI). In addition to PTK 0796, Paratek is also developing other tetracycline antibiotics to treat hospital and community infections based on its novel tetracycline chemistry expertise.

Based upon a growing body of clinical research and as part of its effort to exploit its novel tetracycline derivatives and their unique mechanism of action in selected inflammatory and neurodegenerative conditions, Paratek has an active chemical synthesis effort to produce novel and diverse small molecules, with the goal of developing nonantibacterial tetracycline derivatives with improved activity in serious inflammatory and neurodegenerative diseases. In addition, Paratek is encouraged by early evidence of the ability of tetracycline derivatives to affect mRNA splicing, as in spinal muscular atrophy (SMA). Outside of its tetracycline antibacterial program, Paratek has also identified small molecules that inhibit bacteria-specific transcription factors for Multiple Adaptational Response (MAR) genes which control bacterial virulence and resistance development.

Paratek has active collaborations with Novartis, Warner-Chilcott and FSMA to develop tetracycline-derived small molecule drugs for a range of uses, including bacterial infections, acne & rosacea and SMA. Paratek is privately held and headquartered in Boston, Massachusetts, USA.
