Paratek Pharmaceuticals Announces Initiation of Funding from BARDA for All FDA Required Post-marketing Studies for NUZYRA• (omadacycline)
In connection with the FDA approval of NUZYRA in
“We are eager and well-prepared to conduct these studies, which will now be funded entirely through the BARDA Project BioShield public-private partnership award. The clinical and microbiologic data from these studies will augment the wealth of existing data examining the safety and efficacy of once-daily, oral and intravenous NUZYRA in life-threatening community acquired infections,” said
Under the terms of the contract that are now initiated, reimbursement has begun for all of the
Paratek Statement on COVID-19
We applaud the heroic efforts of medical professionals around the world who are working to protect public health and combat the COVID-19 pandemic. Whether directly treating patients impacted by the virus or implementing containment measures to constrain its transmission, you selflessly put the needs and journey of your patients first.
We at Paratek will strive to do our part during this crisis. The safety of or employees, the healthcare community and payers is paramount. We are taking appropriate steps to protect our employees, healthcare community and payers, following all local and federal requirements, and continually monitoring the situation to provide the appropriate guidance. Paratek has embraced the public health guidance regarding social distancing with all employees now working from home, utilizing a virtual model for meetings and interactions with the healthcare community and payers.
As the global COVID-19 pandemic continues to evolve, to date we have been able to provide an uninterrupted supply of our commercially available antibiotic, NUZYRA®. Based on current inventory levels and expected demand, we do not currently anticipate a shortage of NUZYRA.
Due to the demands on the healthcare system during this unprecedented crisis with COVID-19, the recruitment of our ongoing clinical studies has been paused. At the current time, the only study currently recruiting is our oral only pharmacokinetic study in patients with pneumonia. As the study has not yet completed recruitment, the study will take longer than anticipated. As the situation evolves, we intend to provide future updates on timing of the initiation of recruitment and completion of the study.
NUZYRA• (omadacycline) is a novel antibiotic with both once-daily oral and intravenous (IV) formulations for the treatment of community-acquired bacterial pneumonia (CABP) and acute bacterial skin and skin structure infections (ABSSSI). A modernized tetracycline, NUZYRA is specifically designed to overcome tetracycline resistance and exhibits activity across a spectrum of bacteria, including Gram-positive, Gram-negative, atypicals, and other drug-resistant strains.
Indications and Usage
NUZYRA is a tetracycline class antibacterial indicated for the treatment of adult patients with the following infections caused by susceptible microorganisms:
Community-Acquired Bacterial Pneumonia (CABP) caused by the following: Streptococcus pneumoniae, Staphylococcus aureus (methicillin-susceptible isolates), Haemophilus influenzae, Haemophilus parainfluenzae, Klebsiella pneumoniae, Legionella pneumophila, Mycoplasma pneumoniae, and Chlamydophila pneumoniae.
Acute Bacterial Skin and Skin Structure Infections (ABSSSI) caused by the following: Staphylococcus aureus (methicillin-susceptible and -resistant isolates), Staphylococcus lugdunensis, Streptococcus pyogenes, Streptococcus anginosus grp. (includes S. anginosus, S. intermedius, and S. constellatus), Enterococcus faecalis, Enterobacter cloacae, and Klebsiella pneumoniae.
To reduce the development of drug-resistant bacteria and maintain the effectiveness of NUZYRA and other antibacterial drugs, NUZYRA should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria.
Important Safety Information
NUZYRA is contraindicated in patients with known hypersensitivity to omadacycline or tetracycline class antibacterial drugs, or to any of the excipients.
Warnings and Precautions
Mortality imbalance was observed in the CABP clinical trial with eight deaths (2%) occurring in patients treated with NUZYRA compared to four deaths (1%) in patients treated with moxifloxacin. The cause of the mortality imbalance has not been established. All deaths, in both treatment arms, occurred in patients > 65 years of age; most patients had multiple comorbidities. The causes of death varied and included worsening and/or complications of infection and underlying conditions. Closely monitor clinical response to therapy in CABP patients, particularly in those at higher risk for mortality.
The use of NUZYRA during tooth development (last half of pregnancy, infancy and childhood to the age of eight years) may cause permanent discoloration of the teeth (yellow-gray-brown) and enamel hypoplasia.
The use of NUZYRA during the second and third trimester of pregnancy, infancy and childhood up to the age of eight years may cause reversible inhibition of bone growth.
Hypersensitivity reactions have been reported with NUZYRA. Life-threatening hypersensitivity (anaphylactic) reactions have been reported with other tetracycline-class antibacterial drugs. NUZYRA is structurally similar to other tetracycline-class antibacterial drugs and is contraindicated in patients with known hypersensitivity to tetracycline-class antibacterial drugs. Discontinue NUZYRA if an allergic reaction occurs.
Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents and may range in severity from mild diarrhea to fatal colitis. Evaluate if diarrhea occurs.
NUZYRA is structurally similar to tetracycline-class of antibacterial drugs and may have similar adverse reactions. Adverse reactions including photosensitivity, pseudotumor cerebri, and anti-anabolic action which has led to increased BUN, azotemia, acidosis, hyperphosphatemia, pancreatitis, and abnormal liver function tests, have been reported for other tetracycline-class antibacterial drugs, and may occur with NUZYRA. Discontinue NUZYRA if any of these adverse reactions are suspected.
Prescribing NUZYRA in the absence of a proven or strongly suspected bacterial infection is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.
The most common adverse reactions (incidence ≥2%) are nausea, vomiting, infusion site reactions, alanine aminotransferase increased, aspartate aminotransferase increased, gamma-glutamyl transferase increased, hypertension, headache, diarrhea, insomnia, and constipation.
Patients who are on anticoagulant therapy may require downward adjustment of their anticoagulant dosage while taking NUZYRA.
Absorption of tetracyclines, including NUZYRA is impaired by antacids containing aluminum, calcium, or magnesium, bismuth subsalicylate and iron containing preparations.
Use in Specific Populations
Lactation: Breastfeeding is not recommended during treatment with NUZYRA.
