Paratek Pharmaceuticals, Inc.
PRTK
announced that the FDA has granted an Orphan Drug designation to its sole marketed drug, Nuzyra (omadacycline), for the treatment of infections caused by Nontuberculous Mycobacteria (“NTM”).
The Orphan Drug designation is granted to drugs that are capable of treating rare diseases that affect less than 200,000 people in the United States. This tag also makes the company entitled to certain other benefits, including tax credits related to clinical trial expenses, an exemption from the FDA user fee and marketing exclusivity upon potential approval.
Per the press release, the above Orphan Drug tag includes NTM pulmonary disease caused by Mycobacterium abscessus complex (MABc), for which a phase IIb study on Nuzyra is currently ongoing.
The placebo-controlled phase IIb study is evaluating Nuzyra monotherapy for treating patients with M. abscessus pulmonary disease who are in the early phase of treatment and are not taking other antibiotics. The primary endpoints of the study are to check the improvement in symptoms, and safety and tolerability following 12 weeks of treatment.
Per the company, pulmonary infections caused by M. abscessus affect around 11,500 patients in the United States. Currently, there is no FDA-approved antibiotic therapy for the indication. Hence, if successfully developed and upon potential approval, Nuzyra can provide a new treatment option for the given patient population.
Shares of Paratek have plunged 16.8% so far this year compared with the

’s decrease of 0.2%.

We remind investors that Nuzyra is currently marketed as a once-daily antibiotic with both oral and intravenous formulations, for the treatment of community-acquired bacterial pneumonia and acute bacterial skin and skin structure infections.
Nuzyra generated sales worth $66 million in the first half of 2021, reflecting a significant increase year over year. Potential label expansions to treat other indication will boost the drug’s sales in the days ahead.
We note that, in 2019, the Biomedical Advanced Research and Development Authority (“BARDA”) awarded a contract to Paratek for up to $284.5 million to support the development and manufacturing of Nuzyra in the United States for the treatment of pulmonary anthrax. During the second quarter of 2021, the BARDA accepted the first procurement of Nuzyra, valued at $37.9 million.
