Nabriva Commences Exclusive Distribution of SIVEXTRO® (tedizolid phosphate) in the U.S.
– SIVEXTRO now available under Nabriva’s National Drug Code
– 100% of SIVEXTRO’s net product sales to be recorded by Nabriva
DUBLIN, Ireland and FORT WASHINGTON, Pa., April 15, 2021 (GLOBE NEWSWIRE) — Nabriva Therapeutics plc (NASDAQ: NBRV), a biopharmaceutical company engaged in the commercialization and development of innovative anti-infective agents to treat serious infections, today announced that it has begun exclusive distribution of SIVEXTRO® (tedizolid phosphate) in the United States.
SIVEXTRO is now listed in the National Drug Code (NDC) Directory under the Nabriva label. Since April 12, 2021, Nabriva has been marketing and distributing SIVEXTRO in the United States and certain of its territories as part of an exclusive agreement signed in July 2020 with subsidiaries of Merck & Co. Inc., Kenilworth, N.J., USA (“Merck”), known as MSD outside the United States and Canada. As a result, Nabriva expects to recognize 100% of net product sales of SIVEXTRO in its results of operations beginning on April 12, 2021. SIVEXTRO is an oxazolidinone-class antibacterial indicated in adults and pediatric patients 12 years of age and older for the treatment of acute bacterial skin and skin structure infections (ABSSSI) caused by certain susceptible Gram-positive microorganisms.
Under the terms of the agreement with Merck & Co. Inc., Kenilworth, N.J., USA, Nabriva will continue to procure SIVEXTRO from Merck & Co. Inc., Kenilworth, N.J., USA and be solely responsible for marketing, sales, and distribution of SIVEXTRO in the United States at least through December 31, 2023, with renewable three-year extensions.
To provide community-based commercial and sales services for SIVEXTRO and XENLETA in the United States, Nabriva entered into an agreement with Amplity Health, a leading pharmaceutical contract commercial organization, in July 2020.
About SIVEXTRO® (tedizolid phosphate)
SIVEXTRO was approved by the U.S. Food and Drug Administration in 2014. It is indicated in adults and pediatric patients 12 years of age and older for the treatment of acute bacterial skin and skin structure infections (ABSSSI) caused by susceptible isolates of the following Gram-positive microorganisms: Staphylococcus aureus (including methicillin-resistant (MRSA) and methicillin-susceptible (MSSA) isolates), Streptococcus pyogenes, Streptococcus agalactiae, Streptococcus anginosus group (including Streptococcus anginosus, Streptococcus intermedius and Streptococcus constellatus), and Enterococcus faecalis. To reduce the development of drug-resistant bacteria and maintain the effectiveness of SIVEXTRO and other antibacterial drugs, SIVEXTRO should be used only to treat ABSSSI that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
MRSA has been categorized by the U.S. Centers for Disease Control and Prevention (CDC) as a serious public health threat.1 SIVEXTRO 200 mg is administered once daily orally or as an intravenous (IV) infusion over one hour for six days.
Selected Important Safety Information for SIVEXTRO
Patients with neutropenia: The safety and efficacy of SIVEXTRO in patients with neutropenia (neutrophil counts <1000 cells/mm³) have not been adequately evaluated. In an animal model of infection, the antibacterial activity of SIVEXTRO was reduced in the absence of granulocytes. Alternative therapies should be considered when treating patients with neutropenia.
Clostridioides difficile–associated diarrhea (CDAD), ranging from mild diarrhea to fatal colitis, has been reported with nearly all systemic antibacterial agents, including SIVEXTRO. Evaluate all patients who present with diarrhea following antibacterial drug use. Careful medical history is necessary because CDAD has been reported to occur more than two months after the administration of antibacterial agents. If CDAD is suspected or confirmed, antibacterial use not directed against C. difficile should be discontinued, if possible.
Development of drug-resistant bacteria: Prescribing SIVEXTRO in the absence of a proven or strongly suspected bacterial infection or prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.
Adverse reactions: The most common adverse reactions (≥ 2%) in adults for SIVEXTRO are nausea (7%), headache (5%), diarrhea (4%), vomiting (3%), and dizziness (2%).
In adult patients receiving SIVEXTRO intravenously, infusion- or injection-related adverse reactions including but not limited to: phlebitis, injection- or infusion-site pain or swelling, injection-site reaction, erythema, or induration, and infusion-related reaction occurred (4%).
The most common adverse reactions (>2%) in pediatric patients 12 years of age and older are phlebitis (3%) and increased hepatic transaminases (3%).
Drug interactions with BCRP substrates: SIVEXTRO (when administered orally) can increase the plasma concentrations of orally administered Breast Cancer Resistance Protein (BCRP) substrates and the potential for adverse reactions. Monitor for adverse reactions related to the concomitant BCRP substrates if coadministration cannot be avoided.
