ZEVTERA

ZEVTERA (ceftobiprole medocaril sodium for injection) contains sodium salt of ceftobiprole medocaril, a semisynthetic, cephalosporin antibacterial, for intravenous use. Chemically, ceftobiprole medocaril is (6 R ,7 R )-7-[[(2 Z )-2-(5-amino-1,2,4-thiadiazol-3-yl)-2-hydroxyiminoacetyl]amino]-3-[( E )-[1-[(3 R )-1-[(5-methyl-2-oxo-1,3-dioxol-4-yl)methoxycarbonyl]pyrrolidin-3-yl]-2-oxopyrrolidin-3-ylidene]methyl]-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid. Its molecular weight is 690.6 g/mol. The empirical formula is C 26 H 25 N 8 NaO 11 S 2 . Figure 1 Chemical Structure of ceftobiprole medocaril ZEVTERA vials contain 667 mg of ceftobiprole medocaril sodium (equivalent to 500 mg of ceftobiprole). The powder for injection is a white, yellowish to slightly brownish sterile powder. Each vial includes inactive ingredient citric acid monohydrate (26.3 mg/vial) as a buffer component and sodium hydroxide (q.s.) as a pH adjustment agent. Each vial of ZEVTERA contains approximately 32 mg of sodium. The pH of the reconstituted solution is 4.5–5.5. Chemical Structure

ZEVTERA is a cephalosporin antibacterial indicated for the treatment of: Adult patients with Staphylococcus aureus bloodstream infections (bacteremia) (SAB), including those with right-sided infective endocarditis ( 1.1 ), Adult patients with acute bacterial skin and skin structure infections (ABSSSI) ( 1.2 ), and Adult and pediatric patients (3 months to less than 18 years old) with community-acquired bacterial pneumonia (CABP) ( 1.3 ). 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 bacteria ( 1.4 ). 1.1 Staphylococcus aureus Bloodstream Infection (Bacteremia) ZEVTERA is indicated for the treatment of adult patients with Staphylococcus aureus bloodstream infection (bacteremia) (SAB), including those with right-sided infective endocarditis, caused by methicillin-susceptible and methicillin-resistant isolates . 1.2 Acute Bacterial Skin and Skin Structure Infections ZEVTERA is indicated for the treatment of 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. 1.3 Community-Acquired Bacterial Pneumonia ZEVTERA is indicated for the treatment of adult and pediatric patients (3 months to less than 18 years old) 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. 1.4 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. 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.

In Trial 3, 310 patients received ZEVTERA 667 mg (equivalent to 500 mg of ceftobiprole) every 8 hours as a 2-hour IV infusion, and 322 patients were treated with ceftriaxone 2 grams as a 0.5 hour IV infusion with or without linezolid 600 mg every 12 hours as a 60-minute IV infusion. The dose of ZEVTERA was adjusted based on renal function. The median age of patients treated with ZEVTERA was 56 years, ranging from 18–90 with approximately 36% aged greater than or equal to 65 years. Approximately 62% of patients were White, 45% were from outside Europe or the United States, and 57% were male. Patients across treatment arms received treatment for a median duration of 9 days. Serious Adverse Reactions and Adverse Reactions Leading to Discontinuation In Trial 3, a total of 35/310 (11.3%) patients with CABP treated with ZEVTERA and 37/322 (11.5%) patients with CABP treated with ceftriaxone ± linezolid experienced serious adverse reactions. Discontinuation of treatment due to any adverse reaction occurred in 18/310 (5.8%) of patients treated with ZEVTERA, and 12/322 (3.7%) of patients treated with ceftriaxone ± linezolid. The most common adverse reaction leading to discontinuation in patients treated with ZEVTERA was vomiting, occurring in 4/310 (1.3%). Deaths occurred in 9/310 (2.9%) patients treated with ZEVTERA and 9/322 (2.8%) in patients treated with ceftriaxone ± linezolid. Common Adverse Reactions Table 10 lists the most common adverse reactions occurring in ≥ 2% of CABP adult patients receiving ZEVTERA in Trial 3.

Although HABP/VABP are included in the safety data, the safety and effectiveness of ZEVTERA for the treatment of HABP/VABP have not been established and ZEVTERA is not approved for HABP or VABP. In Trial 4, 386 patients received ZEVTERA 667 mg (equivalent to 500 mg of ceftobiprole) every 8 hours as a 2-hour IV infusion, and 386 patients were treated with ceftazidime 2 grams every 8 hours as a 2-hour IV infusion with or without linezolid 600 mg every 12 hours as a 1-hr infusion. The dose of ZEVTERA and ceftazidime were adjusted based on renal function. The median age of patients treated with ZEVTERA was 62.5 years (range 18 - 95) with approximately 47% aged 65 years or older. Approximately 81% of the patients were White, most were outside of the United States (88%) and 72% were male. Patients across treatment arms received treatment for a median duration of 8 days. Serious Adverse Reactions and Adverse Reactions Leading to Discontinuation In Trial 4, a total of 140/386 (36.3%) HABP/VABP adult patients treated with ZEVTERA and 123/386 (31.9%) HABP/VABP adult patients treated with ceftazidime ± linezolid experienced serious adverse reactions. Discontinuation of treatment due to any adverse reaction occurred in 54/386 (14%) of patients treated with ZEVTERA, and 40/386 (10.4%) of patients treated with ceftazidime ± linezolid. Deaths occurred in 88/386 patients (22.8%) treated with ZEVTERA and 84/386 patients (21.8%) treated with ceftazidime ± linezolid. In the subgroup of patients with VABP, 35/103 patients treated with ZEVTERA died (34.0%) versus 24/102 (23.5%) of the patients treated with ceftazidime ± linezolid. In the subgroup of patients with HABP, 53/283 patients treated with ZEVTERA died (18.7%) versus 60/284 patients treated with ceftazidime ± linezolid (21.1%). Common Adverse Reactions Common adverse reactions occurring in >2% of HABP/VABP adult patients who received ceftobiprole in Trial 4 include diarrhea, hypokalemia, hyponatremia, hepatic enzyme increased, vomiting, anemia, rash, phlebitis, nausea, abdominal pain, and seizures. Adverse Reactions Reported in <2% of Adults Treated with ZEVTERA The following adverse reactions were reported in ZEVTERA-treated adult patients at a rate of less than 2% in Trials 1, 2, 3, and 4: Blood and lymphatic system disorders: Thrombocytosis, Thrombocytopenia Gastrointestinal disorders: Dyspepsia, Dysphagia General disorders and administration site conditions: Fatigue, Chills, Facial swelling, Infusion site pain Immune system disorders: Hypersensitivity, Angioedema, Anaphylactic shock Infections and infestations: Mucocutaneous fungal infections Investigations: Blood lactate dehydrogenase increased, Blood triglycerides increased, Prothrombin time prolonged Psychiatric disorders: Anxiety, Irritability Renal and urinary disorders: Pollakiuria Respiratory, thoracic and mediastinal disorders: Bronchospasm, Wheezing Skin and subcutaneous tissue disorders: Pruritus Vascular disorders: Thrombosis Pediatric Patients with Community-Acquired Bacterial Pneumonia ZEVTERA was evaluated in an active-controlled, randomized, investigator-blinded, multicenter phase 3 study (Trial 5) in pediatric patients aged 3 months to less than 18 years with HABP or CABP requiring hospitalization. Although patients with HABP are included in the safety data, the safety and effectiveness of ZEVTERA for the treatment of HABP has not been established and ZEVTERA is not approved for HABP. In Trial 5, 94 patients received ZEVTERA 13.3 mg/kg (equivalent to 10 mg/kg of ceftobiprole) to 26.7 mg/kg (equivalent to 20 mg/kg of ceftobiprole – higher than the recommended approved dose) [see Dosage and Administration (2.2 , 2.4) ] . ZEVTERA was administered by intravenous infusion every 8 hours, age-adjusted for dose and infusion duration (2-hour or 4-hour infusion). In the comparator arm, 44 patients received either ceftriaxone 50-80 mg/kg IV as a single daily dose (maximum 2 grams/day) for CABP or ceftazidime 50 mg/kg IV every 8 hours (maximum 6 grams/day) for HABP, with or without vancomycin 10-15 mg/kg IV every 6 hours (maximum 2 grams/day). The median age of study patients was 5 years, ranging from 0.6 to 17 years. All patients were from Europe, 100% were classified as White and 56% of patients were male. Serious Adverse Reactions and Adverse Reactions Leading to Discontinuation In Trial 5, a total of 7/94 (7.4%) pediatric patients treated with ZEVTERA and 2/44 (4.5%) patients in the comparator group experienced serious adverse reactions. Discontinuation of treatment due to any adverse reaction occurred in 4/94 (4.3%) of patients treated with ZEVTERA and 0/44 patients treated in the comparator group. Adverse reactions leading to treatment discontinuation in patients who received ZEVTERA included aggravated pneumonia, pleuritis, urticaria, and hypersensitivity, each occurring in 1/94 (1.1%). There were no deaths in either arm of the pediatric study. The most common adverse reactions, occurring in ≥ 2% of pediatric patients treated with ZEVTERA were vomiting (7.4%), headache (3.2%), hepatic enzyme increased (including alanine aminotransferase increased and aspartate aminotransferase increased) (3.2%), diarrhea, infusion site reaction, phlebitis, and pyrexia (all 2.1%). 6.2 Postmarketing Experience The following adverse reactions and altered laboratory tests have been identified during post-approval use of ZEVTERA and ceftobiprole outside of the United States, or other cephalosporin-class antibacterial drugs. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Altered Laboratory Tests : Positive direct Coombs' test, false-positive test for urinary glucose. Blood and lymphatic system disorders : Agranulocytosis, aplastic anemia. Hepatobiliary disorders : Hepatic dysfunction including cholestasis. Immune system disorders : Drug fever, serum sickness-like reaction. Nervous system disorders : Myoclonus. Renal and urinary disorders : Renal dysfunction, toxic nephropathy. Vascular disorders : Hemorrhage, hypertension.

Organic Anion Transporting Polypeptide 1B1/1B3 (OATP1B1/OATP1B3) Substrates: ZEVTERA may increase the plasma concentrations of OATP1B1 and OATP1B3 substrates. Concomitant administration is not recommended ( 7.1 ) 7.1 Organic Anion Transporting Polypeptide 1B1/1B3 (OATP1B1/OATP1B3) Substrates ZEVTERA may increase the plasma concentrations of OATP1B1 and OATP1B3 substrates. Concomitant administration is not recommended [see Clinical Pharmacology (12.3) ]. 7.2 Drug-Laboratory Test Interactions Dipstick Tests ZEVTERA may result in false-positive results in dipstick tests (urine protein, ketones, or occult blood). Use alternate clinical laboratory methods of testing to confirm positive tests. Serological Testing Treatment with ZEVTERA has the potential to interfere with serological testing, such as the Coombs test. In clinical studies there was no evidence of hemolytic anemia in adults or children. However, the possibility that hemolytic anemia may occur cannot be ruled out. Patients experiencing anemia during or after treatment should be investigated for this possibility.
