About ZEVTERA ® (ceftobiprole medocaril sodium for injection) Ceftobiprole, the active moiety of the prodrug ceftobiprole medocaril, is an advanced-generation cephalosporin antibiotic for intravenous administration, with rapid bactericidal activity against a wide range of Gram-positive bacteria, such as Staphylococcus aureus , including methicillin-resistant strains (MRSA), and Gram-negative bacteria. Outside the U.S., the brand is currently approved and marketed in several European countries and beyond as ZEVTERA ® and Mabelio ® for the treatment of adult patients with hospital-acquired bacterial pneumonia (HABP), excluding ventilator-associated bacterial pneumonia (VABP), and for the treatment of community-acquired bacterial pneumonia (CABP). Basilea has entered into license and distribution agreements covering more than 80 countries. INDICATIONS & USAGE Indications ZEVTERA ® (ceftobiprole medocaril sodium for injection), for intravenous use, is indicated for the treatment of: Adult patients with Staphylococcus aureus bloodstream infections (bacteremia) (SAB), including those with right-sided infective endocarditis, caused by methicillin-susceptible and methicillin-resistant isolates. Adult patients with acute bacterial skin and skin structure infections (ABSSSI) caused by susceptible isolates of the following gram-positive and gram-negative microorganisms: Staphylococcus aureus (methicillin-susceptible and methicillin-resistant isolates), Streptococcus pyogenes, and Klebsiella pneumoniae . Adult and pediatric patients (3 months to less than 18 years) with community-acquired bacterial pneumonia (CABP) caused by susceptible isolates of the following gram-positive and gram-negative microorganisms: Staphylococcus aureus (methicillin-susceptible isolates), Streptococcus pneumoniae, Haemophilus influenzae , Haemophilus parainfluenzae , Escherichia coli , and Klebsiella pneumoniae . Usage To reduce the development of drug-resistant bacteria and maintain the effectiveness of ZEVTERA and other antibacterial drugs, ZEVTERA should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. IMPORTANT SAFETY INFORMATION Contraindications ZEVTERA is contraindicated in patients with a known history of severe hypersensitivity to ZEVTERA, or to other members of the cephalosporin class. Warnings and Precautions Increased mortality with unapproved use in ventilator-associated bacterial pneumonia (VABP) Patients: The safety and effectiveness of ZEVTERA for the treatment of VABP has not been established and the use of ZEVTERA for VABP is not approved. Serious hypersensitivity reactions, including anaphylaxis, were observed in ZEVTERA-treated patients in clinical trials. Serious and occasionally fatal hypersensitivity reactions and serious skin reactions have been reported in patients receiving beta-lactam antibacterial drugs. Before therapy with ZEVTERA is instituted, careful inquiry about previous hypersensitivity reactions to other cephalosporins, penicillins, or other beta-lactam antibacterial drugs should be made. Maintain clinical supervision if this product is to be given to a penicillin- or other beta-lactam-allergic patient, because cross sensitivity among beta-lactam antibacterial agents has been established. Discontinue ZEVTERA if a hypersensitivity reaction occurs, and institute appropriate treatment. Seizures and other adverse central nervous system (CNS) reactions have been reported during treatment with ZEVTERA and other cephalosporins. If CNS adverse reactions, including seizures, occur, evaluate patients to determine whether ZEVTERA should be discontinued. Clostridioides difficile -associated diarrhea (CDAD) has been reported with nearly all systemic antibacterial agents, including ZEVTERA, and may range in severity from mild diarrhea to fatal colitis. If CDAD is suspected or confirmed, the risk/benefit of continuing treatment with ZEVTERA should be assessed. Adverse Reactions SAB (adult patients): The most common adverse reactions occurring in ≥ 2% of adult patients were anemia, nausea, hypokalemia, vomiting, hepatic enzyme and bilirubin increased, diarrhea, blood creatinine increased, hypertension, leukopenia, pyrexia, abdominal pain, fungal infection, headache, and dyspnea. ABSSSI (adult patients): The most common adverse reactions occurring in ≥ 2% of adult patients were nausea, diarrhea, headache, injection site reaction, hepatic enzyme increase, rash, vomiting, and dysgeusia. CABP (adult and pediatric patients 3 months to less than 18 years of age): Adult Patients: The most common adverse reactions occurring in ≥ 2% of adult patients were nausea, hepatic enzyme increased, vomiting, diarrhea, headache, rash, insomnia, abdominal pain, phlebitis, hypertension, and dizziness. Pediatric Patients: The most common adverse reactions occurring in ≥ 2% of pediatric patients were vomiting, headache, hepatic enzyme increased, diarrhea, infusion site reaction, phlebitis, and pyrexia. About NUZOLVENCE® (zoliflodacin) for oral suspension NUZOLVENCE is a first-in-class, single-dose, oral antibiotic FDA-approved for the treatment of uncomplicated urogenital gonorrhea, including strains resistant to current first-line therapies. NUZOLVENCE is a spiropyrimidinetrione bacterial type II topoisomerase inhibitor indicated for the treatment of uncomplicated urogenital gonorrhea due to Neisseria gonorrhoeae in adults and pediatric patients 12 years of age and older, weighing at least 35 kg. The NUZOLVENCE mechanism of action is distinct from that of currently approved antibiotics and has demonstrated activity against drug-resistant Neisseria gonorrhoeae . Important Safety Information (ISI) Indication and Usage Indication NUZOLVENCE® is a spiropyrimidinetrione bacterial type II topoisomerase inhibitor indicated for the treatment of uncomplicated urogenital gonorrhea due to Neisseria gonorrhoeae in adults and pediatric patients 12 years of age and older, weighing at least 35 kg. Usage to Reduce Development of Drug-Resistant Bacteria: To reduce the development of drug-resistant bacteria and maintain the effectiveness of NUZOLVENCE and other antibacterial drugs, NUZOLVENCE should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria. Contraindications Known history of hypersensitivity to NUZOLVENCE. Concomitant use with moderate or strong CYP3A4 inducers because this is predicted to result in decreased plasma concentrations of zoliflodacin and may reduce the NUZOLVENCE efficacy. Warnings and Precautions Embryo-Fetal Toxicity: Potential Risk for Pregnant Females Based on data from animal studies, NUZOLVENCE may cause fetal harm when administered to a pregnant female at clinically relevant doses. Avoid use during pregnancy. Advise pregnant females about the potential risk to the fetus with maternal exposure to NUZOLVENCE. Obtain a pregnancy test prior to initiation in persons of reproductive potential. Embryo-Fetal Toxicity: Potential Risk Related to Males with Female Partners of Reproductive Potential: Based on data from an animal toxicity study, the risk of early pregnancy loss may be increased in female partners of males treated with NUZOLVENCE. Advise males with female partners of reproductive potential to use effective contraception for at least 3 months after NUZOLVENCE administration. Testicular Toxicity and Risks to Male Fertility: Based on findings from animal studies, NUZOLVENCE may cause testicular toxicity and impair male fertility. An assessment of spermatogenesis has not been conducted in humans. Advise males that NUZOLVENCE may cause testicular toxicity and impair male fertility. Hypersensitivity Reactions: Hypersensitivity reactions, including rash and pruritus, have been reported in patients receiving NUZOLVENCE. Before therapy with NUZOLVENCE is instituted, carefully inquire about previous hypersensitivity reactions to NUZOLVENCE. If an allergic reaction to NUZOLVENCE occurs, discontinue NUZOLVENCE and institute appropriate supportive measures. Clostridioides difficile Infection (CDI): CDI 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. Development of Drug-Resistant Bacteria: Prescribing NUZOLVENCE 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%) are headache, dizziness, nausea, and diarrhea. Laboratory abnormalities (neutropenia, leukopenia) were also observed. Drug Interactions Concomitant use with moderate or strong CYP3A4 inducers is contraindicated. Use in Specific Populations Pregnancy: Based on findings from animal studies, NUZOLVENCE may cause fetal malformations or increased embryo-fetal loss when administered to a pregnant female. A postmarketing descriptive pregnancy safety study is available for NUZOLVENCE. If exposure occurs during pregnancy, pregnant females or their healthcare providers should report the pregnancy to Entasis Therapeutics at 1-800-651-3861. Lactation: There are no data on the presence of zoliflodacin in either human or animal milk, effects on the breastfed infant, or effects on milk production. If NUZOLVENCE is present in breast milk, intestinal flora alteration in the breastfed infant could occur. Females and Males of Reproductive Potential: Based on animal studies, NUZOLVENCE may cause fetal malformations when administered to a pregnant female at clinically relevant doses. Additionally, based on data from an animal study, the risk of early pregnancy loss may be increased in partners of males treated with NUZOLVENCE. Pregnancy Testing: Obtain a pregnancy test in females of reproductive potential prior to initiating treatment with NUZOLVENCE. Contraception: Advise males with female partners of reproductive potential to use effective contraception for at least 3 months after their single-dose treatment of NUZOLVENCE. Infertility: Based on data from repeat-dose animal toxicity and fertility studies, NUZOLVENCE may cause testicular toxicity and impair male fertility. Pediatric Use: The safety and effectiveness of NUZOLVENCE in pediatric patients younger than 12 years of age or weighing less than 35 kg have not been established. Geriatric Use: Clinical studies of NUZOLVENCE did not include sufficient numbers of patients aged 65 years and older to determine whether they respond differently than younger patients.
