Cefepime

6 ADVERSE REACTIONS The following adverse reactions are discussed in the Warnings and Precautions section and below: Hypersensitivity Reactions [see Warnings and Precautions ( 5.1 )] Neurotoxicity [see Warnings and Precautions ( 5.2 )] Clostridioides difficile -Associated Diarrhea [see Warnings and Precautions ( 5.3 )] The most common adverse reactions (incidence ≥ 1%) were local reactions, positive Coombs’ test, decreased phosphorous, increased ALT and AST, increased PT and PTT and rash. ( 6.1 ) At the highest dose (2 g every 8 hours), incidence of adverse reactions was ≥ 1% for rash, diarrhea, nausea, vomiting, pruritus, fever, and headache. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Fresenius Kabi USA, LLC at 1-800-551-7176 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. In clinical trials using multiple doses of cefepime, 4,137 patients were treated with the recommended dosages of cefepime (500 mg to 2 g intravenous every 12 hours). There were no deaths or permanent disabilities thought related to drug toxicity. Sixty-four (1.5%) patients discontinued medication due to adverse reactions. Thirty-three (51%) of these 64 patients who discontinued therapy did so because of rash. The percentage of cefepime-treated patients who discontinued study drug because of drug-related adverse reactions was similar at daily doses of 500 mg, 1 g, and 2 g every 12 hours (0.8%, 1.1%, and 2%, respectively). However, the incidence of discontinuation due to rash increased with the higher recommended doses. The following adverse reactions (Table 5) were identified in clinical trials conducted in North America (n=3,125 cefepime-treated patients). Table 5: Adverse Reactions in Cefepime Multiple-Dose Dosing Regimens Clinical Trials in North America Incidence equal to or greater than 1% Local adverse reactions (3%), including phlebitis (1.3%), pain and/or inflammation (0.6%)*; rash (1.1%) Incidence less than 1% but greater than 0.1% Colitis (including pseudomembranous colitis), diarrhea, erythema, fever, headache, nausea, oral moniliasis, pruritus, urticaria, vaginitis, vomiting, anemia At the higher dose of 2 g every 8 hours, the incidence of adverse reactions was higher among the 795 patients who received this dose of cefepime. They consisted of rash (4%), diarrhea (3%), nausea (2%), vomiting (1%), pruritus (1%), fever (1%), and headache (1%). The following (Table 6) adverse laboratory changes, with cefepime, were seen during clinical trials conducted in North America. Table 6: Adverse Laboratory Changes in Cefepime Multiple-Dose Dosing Regimens Clinical Trials in North America Incidence equal to or greater than 1% Positive Coombs’ test (without hemolysis) (16.2%); decreased phosphorus (2.8%); increased Alanine Transaminase (ALT) (2.8%), Aspartate Transaminase (AST) (2.4%), eosinophils (1.7%); abnormal PTT (1.6%), Prothrombin Time (PT) (1.4%) Incidence less than 1% but greater than 0.1% Increased alkaline phosphatase, Blood Urea Nitrogen (BUN), calcium, creatinine, phosphorus, potassium, total bilirubin; decreased calcium*, hematocrit, neutrophils, platelets, White Blood Cells (WBC) * Hypocalcemia was more common among elderly patients. Clinical consequences from changes in either calcium or phosphorus were not reported. A similar safety profile was seen in clinical trials of pediatric patients. 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of cefepime for injection. 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. In addition to the adverse reactions reported during the North American clinical trials with cefepime, the following adverse reactions have been reported during worldwide postmarketing experience. Encephalopathy (disturbance of consciousness including confusion, hallucinations, stupor, and coma), aphasia, myoclonus, seizures, and nonconvulsive status epilepticus have been reported [see Warnings and Precautions ( 5.2 )]. Anaphylaxis including anaphylactic shock, transient leukopenia, neutropenia, agranulocytosis and thrombocytopenia, have been reported. 6.3 Cephalosporin-Class Adverse Reactions In addition to the adverse reactions listed above that have been observed in patients treated with cefepime, the following adverse reactions and altered laboratory tests have been reported for cephalosporin-class antibacterial drugs: Stevens-Johnson syndrome, erythema multiforme, toxic epidermal necrolysis, renal dysfunction, toxic nephropathy, aplastic anemia, hemolytic anemia, hemorrhage, hepatic dysfunction including cholestasis, and pancytopenia.

The usual recommended dosage in pediatric patients up to 40 kg in weight for durations as given above for adults is: 50 mg per kg per dose, administered every 12 hours for uncomplicated and complicated urinary tract infections (including pyelonephritis), uncomplicated skin and skin structure infections, and pneumonia (see below). For moderate to severe pneumonia due to P. aeruginosa give 50 mg per kg per dose, every 8 hours. 50 mg per kg per dose, every 8 hours for febrile neutropenic patients. 2.3 Dosage Adjustments in Patients with Renal Impairment Adult Patients Adjust the dose of cefepime for injection in patients with creatinine clearance less than or equal to 60 mL/min to compensate for the slower rate of renal elimination. In these patients, the recommended initial dose of cefepime for injection should be the same as in patients with CrCL greater than 60 mL/min except in patients undergoing hemodialysis. The recommended doses of cefepime for injection in patients with renal impairment are presented in Table 2. When only serum creatinine is available, the following formula (Cockcroft and Gault equation) 1 may be used to estimate creatinine clearance. The serum creatinine should represent a steady state of renal function: Males: Creatinine Clearance (mL/min) = Weight (kg) x (140 – age) 72 x serum creatinine (mg/dL) Females: 0.85 x above value Table 2: Recommended Dosing Schedule for Cefepime for Injection in Adult Patients with Creatinine Clearance Less Than or Equal to 60 mL/min Clearance (mL/min) Creatinine Recommended Maintenance Schedule Greater than 60 500 mg every 12 hours 1 g every 12 hours 2 g every 12 hours 2 g every 8 hours 30 to 60 500 mg every 24 hours 1 g every 24 hours 2 g every 24 hours 2 g every 12 hours 11 to 29 500 mg every 24 hours 500 mg every 24 hours 1 g every 24 hours 2 g every 24 hours Less than 11 250 mg every 24 hours 250 mg every 24 hours 500 mg every 24 hours 1 g every 24 hours Continuous Ambulatory Peritoneal Dialysis (CAPD) 500 mg every 48 hours 1 g every 48 hours 2 g every 48 hours 2 g every 48 hours Hemodialysis* 1 g on day 1, then 500 mg every 24 hours thereafter 1 g every 24 hours *On hemodialysis days, cefepime should be administered following hemodialysis. Whenever possible, cefepime should be administered at the same time each day. In patients undergoing Continuous Ambulatory Peritoneal Dialysis (CAPD), cefepime for injection may be administered at the recommended doses at a dosage interval of every 48 hours (see Table 2). In patients undergoing hemodialysis, approximately 68% of the total amount of cefepime present in the body at the start of dialysis will be removed during a 3-hour dialysis period. The dosage of cefepime for injection for hemodialysis patients is 1 g on Day 1 followed by 500 mg every 24 hours for the treatment of all infections except febrile neutropenia, which is 1 g every 24 hours. Cefepime for injection should be administered at the same time each day and following the completion of hemodialysis on hemodialysis days (see Table 2). Pediatric Patients Data in pediatric patients with impaired renal function are not available; however, since cefepime pharmacokinetics are similar in adults and pediatric patients [see Clinical Pharmacology ( 12.3 )] , changes in the dosing regimen proportional to those in adults (see Tables 1 and 2) are recommended for pediatric patients. 2.4 Preparation of Cefepime for Injection for Intravenous Infusion Vials Constitute the 1 gram, or 2 grams vial, of cefepime for injection with the one of the following diluents: Sterile Water for Injection 0.9% Sodium Chloride Injection 5% Dextrose Injection 0.5% or 1% Lidocaine Hydrochloride Injection Sterile Bacteriostatic Water for Injection with Parabens or Benzyl Alcohol Dilute the reconstituted solution with one of the following compatible infusion solutions prior to intravenous infusion (Refer to Table 3 below for the amount of diluent to be added to each vial and the amount of the reconstituted solution to be withdrawn): 0.9% Sodium Chloride Injection 5% and 10% Dextrose Injection M/6 Sodium Lactate Injection 5% Dextrose and 0.9% Sodium Chloride Injection Lactated Ringers and 5% Dextrose Injection Normosol ® -R and Normosol ® -M in 5% Dextrose Injection Parenteral drugs should be inspected visually for particulate matter before administration. If particulate matter is evident in reconstituted fluids, the drug solution should be discarded. Administer the resulting intravenous infusion over approximately 30 minutes. Intermittent intravenous infusion with a Y-type administration set can be accomplished with compatible solutions. However, during infusion of a solution containing cefepime, it is desirable to discontinue the other solution. 2.5 Preparation of Cefepime for Injection for Intramuscular Administration Constitute cefepime for injection vials 1 gram and 2 grams with one of the following diluents: Sterile Water for Injection, 0.9% Sodium Chloride, 5% Dextrose Injection, 0.5% or 1% Lidocaine Hydrochloride, or Sterile Bacteriostatic Water for Injection with Parabens or Benzyl Alcohol.

1 INDICATIONS AND USAGE Cefepime for injection is a cephalosporin antibacterial indicated for the treatment of the following infections caused by susceptible strains of the designated microorganisms: Pneumonia. ( 1.1 ) Empiric therapy for febrile neutropenic patients. ( 1.2 ) Uncomplicated and complicated urinary tract infections (including pyelonephritis). ( 1.3 ) Uncomplicated skin and skin structure infections. ( 1.4 ) Complicated intra-abdominal infections (used in combination with metronidazole) in adults. ( 1.5 ) To reduce the development of drug-resistant bacteria and maintain the effectiveness of cefepime for injection and other antibacterial drugs, cefepime for injection should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria. ( 1.6 ) 1.1 Pneumonia Cefepime for injection is indicated in the treatment of pneumonia (moderate to severe) caused by susceptible strains of Streptococcus pneumoniae , including cases associated with concurrent bacteremia, Pseudomonas aeruginosa , Klebsiella pneumoniae , or Enterobacter species. 1.2 Empiric Therapy for Febrile Neutropenic Patients Cefepime for injection as monotherapy is indicated for empiric treatment of febrile neutropenic patients. In patients at high risk for severe infection (including patients with a history of recent bone marrow transplantation, with hypotension at presentation, with an underlying hematologic malignancy, or with severe or prolonged neutropenia), antimicrobial monotherapy may not be appropriate. Insufficient data exist to support the efficacy of cefepime monotherapy in such patients [see Clinical Studies ( 14.1 )] . 1.3 Uncomplicated and Complicated Urinary Tract Infections (including pyelonephritis) Cefepime for injection is indicated in the treatment of uncomplicated and complicated urinary tract infections (including pyelonephritis) caused by susceptible isolates of Escherichia coli or Klebsiella pneumoniae , when the infection is severe, or caused by Escherichia coli , Klebsiella pneumoniae , or Proteus mirabilis , when the infection is mild to moderate, including cases associated with concurrent bacteremia with these bacteria. 1.4 Uncomplicated Skin and Skin Structure Infections Cefepime for injection is indicated in the treatment of uncomplicated skin and skin structure infections caused by Staphylococcus aureus (methicillin-susceptible isolates only) or Streptococcus pyogenes . 1.5 Complicated Intra-abdominal Infections (used in combination with metronidazole) Cefepime for injection is indicated in the treatment of complicated intra-abdominal infections (used in combination with metronidazole) in adults caused by susceptible isolates of Escherichia coli , viridans group streptococci, Pseudomonas aeruginosa , Klebsiella pneumoniae , Enterobacter species, or Bacteroides fragilis [see Clinical Studies ( 14.2 )] . 1.6 Usage To reduce the development of drug-resistant bacteria and maintain the effectiveness of cefepime for injection and other antibacterial drugs, cefepime for injection 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.

10 OVERDOSAGE Patients who receive an overdose should be carefully observed and given supportive treatment. In the presence of renal insufficiency, hemodialysis, not peritoneal dialysis, is recommended to aid in the removal of cefepime from the body. Symptoms of overdose include encephalopathy (disturbance of consciousness including confusion, hallucinations, stupor, and coma), myoclonus, seizures, neuromuscular excitability, and nonconvulsive status epilepticus [see Warnings and Precautions ( 5.2 ), Adverse Reactions ( 6.2 ), Dosage and Administration ( 2.3 )] .

7 DRUG INTERACTIONS Aminoglycosides: increased potential of nephrotoxicity and ototoxicity. Monitor renal function. ( 7.2 ) Diuretics: nephrotoxicity has been reported following concomitant administration of other cephalosporins with potent diuretics such as furosemide. Monitor renal function. ( 7.3 ) 7.1 Drug/Laboratory Test Interactions The administration of cefepime may result in a false-positive reaction for glucose in the urine with certain methods. It is recommended that glucose tests based on enzymatic glucose oxidase reactions be used. 7.2 Aminoglycosides Monitor renal function if aminoglycosides are to be administered with cefepime for injection because of the increased potential of nephrotoxicity and ototoxicity of aminoglycoside antibacterial drugs. 7.3 Diuretics Nephrotoxicity has been reported following concomitant administration of other cephalosporins with potent diuretics such as furosemide. Monitor renal function when cefepime is concomitantly administered with potent diuretics.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Cefepime is a cephalosporin antibacterial drug [see Microbiology ( 12.4 )] . 12.2 Pharmacodynamics Similar to other beta-lactam antimicrobial agents, the time that the unbound plasma concentration of cefepime exceeds the MIC of the infecting organism has been shown to best correlate with efficacy in animal models of infection. However, the pharmacokinetic/pharmacodynamics relationship for cefepime has not been evaluated in patients. 12.3 Pharmacokinetics Pharmacokinetic parameters for cefepime in healthy adult male volunteers (n=9) following single 30­-minute infusions (IV) of cefepime 500 mg, 1 g, and 2 g are summarized in Table 7. Elimination of cefepime is principally via renal excretion with an average (±SD) half-life of 2 (±0.3) hours and total body clearance of 120 (±8) mL/min in healthy volunteers. Cefepime pharmacokinetics are linear over the range 250 mg to 2 g. There is no evidence of accumulation in healthy adult male volunteers (n=7) receiving clinically relevant doses for a period of 9 days. Table 7: Mean Pharmacokinetic Parameters for Cefepime (±SD), Intravenous Administration Cefepime for Injection Parameter 500 mg IV 1 g IV 2 g IV C max , mcg/mL 39.1 (3.5) 81.7 (5.1) 163.9 (25.3) AUC, h•mcg/mL 70.8 (6.7) 148.5 (15.1) 284.8 (30.6) Number of subjects (male) 9 9 9 Pharmacokinetic parameters for cefepime following a single intramuscular injection are summarized in Table 8. The pharmacokinetics of cefepime are linear over the range of 500 mg to 2 g intramuscularly and do not vary with respect to treatment duration. Table 8: Mean Pharmacokinetic Parameters for Cefepime (±SD), Intramuscular Administration Cefepime for Injection Parameter 500 mg IM 1 g IM 2 g IM C max , mcg/mL 13.9 (3.4) 29.6 (4.4) 57.5 (9.5) T max , h 1.4 (0.9) 1.6 (0.4) 1.5 (0.4) AUC, h•mcg/mL 60 (8) 137 (11) 262 (23) Number of subjects (male) 6 6 12 Absorption Following intramuscular (IM) administration, cefepime is completely absorbed. Distribution The average steady-state volume of distribution of cefepime is 18 (±2) L. The serum protein binding of cefepime is approximately 20% and is independent of its concentration in serum. Concentrations of cefepime achieved in specific tissues and body fluids are listed in Table 9. Table 9: Mean Concentrations of Cefepime in Specific Body Fluids (mcg/mL) or Tissues (mcg/g) Tissue or Fluid Dose/ Route # of Patients Mean Time of Sample Post-Dose (h) Mean Concentration Blister Fluid 2 g IV 6 1.5 81.4 mcg/mL Bronchial Mucosa 2 g IV 20 4.8 24.1 mcg/g Sputum 2 g IV 5 4 7.4 mcg/mL Urine 500 mg IV 1 g IV 2 g IV 8 12 12 0 to 4 0 to 4 0 to 4 292 mcg/mL 926 mcg/mL 3,120 mcg/mL Bile 2 g IV 26 9.4 17.8 mcg/mL Peritoneal Fluid 2 g IV 19 4.4 18.3 mcg/mL Appendix 2 g IV 31 5.7 5.2 mcg/g Gallbladder 2 g IV 38 8.9 11.9 mcg/g Prostate 2 g IV 5 1 31.5 mcg/g Data suggest that cefepime does cross the inflamed blood-brain barrier. The clinical relevance of these data is uncertain at this time. Metabolism and Excretion Cefepime is metabolized to N-methylpyrrolidine (NMP) which is rapidly converted to the N-oxide (NMP-N-oxide). Urinary recovery of unchanged cefepime accounts for approximately 85% of the administered dose. Less than 1% of the administered dose is recovered from urine as NMP, 6.8% as NMP-N-oxide, and 2.5% as an epimer of cefepime. Because renal excretion is a significant pathway of elimination, patients with renal dysfunction and patients undergoing hemodialysis require dosage adjustment [see Dosage and Administration ( 2.3 )] . Specific Populations Patients with Renal impairment Cefepime pharmacokinetics have been investigated in patients with various degrees of renal impairment (n=30). The average half-life in patients requiring hemodialysis was 13.5 (±2.7) hours and in patients requiring continuous peritoneal dialysis was 19 (±2) hours. Cefepime total body clearance decreased proportionally with creatinine clearance in patients with abnormal renal function, which serves as the basis for dosage adjustment recommendations in this group of patients [see Dosage and Administration ( 2.3 )] . Patients with Hepatic impairment The pharmacokinetics of cefepime were unaltered in patients with hepatic impairment who received a single 1 g dose (n=11). Geriatric patients Cefepime pharmacokinetics have been investigated in elderly (65 years of age and older) men (n=12) and women (n=12) whose mean (SD) creatinine clearance was 74 (±15) mL/min. There appeared to be a decrease in cefepime total body clearance as a function of creatinine clearance. Therefore, dosage administration of cefepime in the elderly should be adjusted as appropriate if the patient’s creatinine clearance is 60 mL/min or less [see Dosage and Administration ( 2.3 )] . Pediatric patients Cefepime pharmacokinetics have been evaluated in pediatric patients from 2 months to 11 years of age following single and multiple doses on every 8 hours (n=29) and every 12 hours (n=13) schedules. Following a single intravenous dose, total body clearance and the steady-state volume of distribution averaged 3.3 (±1) mL/min/kg and 0.3 (±0.1) L/kg, respectively. The urinary recovery of unchanged cefepime was 60.4 (±30.4)% of the administered dose, and the average renal clearance was 2 (±1.1) mL/min/kg. There were no significant effects of age or gender (25 male vs. 17 female) on total body clearance or volume of distribution, corrected for body weight. No accumulation was seen when cefepime was given at 50 mg per kg every 12 hours (n=13), while C max , AUC, and t ½ were increased about 15% at steady state after 50 mg per kg every 8 hours. The exposure to cefepime following a 50 mg per kg intravenous dose in a pediatric patient is comparable to that in an adult treated with a 2 g intravenous dose. The absolute bioavailability of cefepime after an intramuscular dose of 50 mg per kg was 82.3 (±15)% in eight patients. 12.4 Microbiology Mechanism of Action Cefepime is a bactericidal drug that acts by inhibition of bacterial cell wall synthesis. Cefepime has a broad spectrum of in vitro activity that encompasses a wide range of Gram-positive and Gram-negative bacteria. Within bacterial cells, the molecular targets of cefepime are the penicillin binding proteins (PBP). Antimicrobial Activity Cefepime has been shown to be active against most isolates of the following microorganisms, both in vitro and in clinical infections as described in the Indications and Usage section ( 1 ). Gram-negative Bacteria Enterobacter spp. Escherichia coli Klebsiella pneumoniae Proteus mirabilis Pseudomonas aeruginosa Gram-positive Bacteria Staphylococcus aureus (methicillin-susceptible isolates only) Streptococcus pneumoniae Streptococcus pyogenes Viridans group streptococci The following in vitro data are available, but their clinical significance is unknown. At least 90 percent of the following bacteria exhibit an in vitro minimum inhibitory concentration (MIC) less than or equal to the susceptible breakpoint for cefepime against isolates of similar genus or organism group. However, the efficacy of cefepime in treating clinical infections due to these bacteria has not been established in adequate and well-controlled clinical trials. Gram-positive Bacteria Staphylococcus epidermidis (methicillin-susceptible isolates only) Staphylococcus saprophyticus Streptococcus agalactiae NOTE: Most isolates of enterococci, e.g., Enterococcus faecalis , and methicillin-resistant staphylococci are resistant to cefepime. Gram-negative Bacteria Acinetobacter calcoaceticus subsp. lwoffii Citrobacter diversus Citrobacter freundii Enterobacter agglomerans Haemophilus influenzae Hafnia alvei Klebsiella oxytoca Moraxella catarrhalis Morganella morganii Proteus vulgaris Providencia rettgeri Providencia stuartii Serratia marcescens NOTE: Cefepime is inactive against many isolates of Stenotrophomonas maltophilia .

12.3 Pharmacokinetics Pharmacokinetic parameters for cefepime in healthy adult male volunteers (n=9) following single 30­-minute infusions (IV) of cefepime 500 mg, 1 g, and 2 g are summarized in Table 7. Elimination of cefepime is principally via renal excretion with an average (±SD) half-life of 2 (±0.3) hours and total body clearance of 120 (±8) mL/min in healthy volunteers. Cefepime pharmacokinetics are linear over the range 250 mg to 2 g. There is no evidence of accumulation in healthy adult male volunteers (n=7) receiving clinically relevant doses for a period of 9 days.

The pharmacokinetics of cefepime are linear over the range of 500 mg to 2 g intramuscularly and do not vary with respect to treatment duration.

Distribution The average steady-state volume of distribution of cefepime is 18 (±2) L. The serum protein binding of cefepime is approximately 20% and is independent of its concentration in serum. Concentrations of cefepime achieved in specific tissues and body fluids are listed in Table 9. Table 9: Mean Concentrations of Cefepime in Specific Body Fluids (mcg/mL) or Tissues (mcg/g) Tissue or Fluid Dose/ Route # of Patients Mean Time of Sample Post-Dose (h) Mean Concentration Blister Fluid 2 g IV 6 1.5 81.4 mcg/mL Bronchial Mucosa 2 g IV 20 4.8 24.1 mcg/g Sputum 2 g IV 5 4 7.4 mcg/mL Urine 500 mg IV 1 g IV 2 g IV 8 12 12 0 to 4 0 to 4 0 to 4 292 mcg/mL 926 mcg/mL 3,120 mcg/mL Bile 2 g IV 26 9.4 17.8 mcg/mL Peritoneal Fluid 2 g IV 19 4.4 18.3 mcg/mL Appendix 2 g IV 31 5.7 5.2 mcg/g Gallbladder 2 g IV 38 8.9 11.9 mcg/g Prostate 2 g IV 5 1 31.5 mcg/g Data suggest that cefepime does cross the inflamed blood-brain barrier. The clinical relevance of these data is uncertain at this time. Metabolism and Excretion Cefepime is metabolized to N-methylpyrrolidine (NMP) which is rapidly converted to the N-oxide (NMP-N-oxide). Urinary recovery of unchanged cefepime accounts for approximately 85% of the administered dose. Less than 1% of the administered dose is recovered from urine as NMP, 6.8% as NMP-N-oxide, and 2.5% as an epimer of cefepime. Because renal excretion is a significant pathway of elimination, patients with renal dysfunction and patients undergoing hemodialysis require dosage adjustment [see Dosage and Administration ( 2.3 )] . Specific Populations Patients with Renal impairment Cefepime pharmacokinetics have been investigated in patients with various degrees of renal impairment (n=30). The average half-life in patients requiring hemodialysis was 13.5 (±2.7) hours and in patients requiring continuous peritoneal dialysis was 19 (±2) hours. Cefepime total body clearance decreased proportionally with creatinine clearance in patients with abnormal renal function, which serves as the basis for dosage adjustment recommendations in this group of patients [see Dosage and Administration ( 2.3 )] . Patients with Hepatic impairment The pharmacokinetics of cefepime were unaltered in patients with hepatic impairment who received a single 1 g dose (n=11). Geriatric patients Cefepime pharmacokinetics have been investigated in elderly (65 years of age and older) men (n=12) and women (n=12) whose mean (SD) creatinine clearance was 74 (±15) mL/min. There appeared to be a decrease in cefepime total body clearance as a function of creatinine clearance. Therefore, dosage administration of cefepime in the elderly should be adjusted as appropriate if the patient’s creatinine clearance is 60 mL/min or less [see Dosage and Administration ( 2.3 )] . Pediatric patients Cefepime pharmacokinetics have been evaluated in pediatric patients from 2 months to 11 years of age following single and multiple doses on every 8 hours (n=29) and every 12 hours (n=13) schedules. Following a single intravenous dose, total body clearance and the steady-state volume of distribution averaged 3.3 (±1) mL/min/kg and 0.3 (±0.1) L/kg, respectively. The urinary recovery of unchanged cefepime was 60.4 (±30.4)% of the administered dose, and the average renal clearance was 2 (±1.1) mL/min/kg. There were no significant effects of age or gender (25 male vs. 17 female) on total body clearance or volume of distribution, corrected for body weight. No accumulation was seen when cefepime was given at 50 mg per kg every 12 hours (n=13), while C max , AUC, and t ½ were increased about 15% at steady state after 50 mg per kg every 8 hours. The exposure to cefepime following a 50 mg per kg intravenous dose in a pediatric patient is comparable to that in an adult treated with a 2 g intravenous dose. The absolute bioavailability of cefepime after an intramuscular dose of 50 mg per kg was 82.3 (±15)% in eight patients.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility No animal carcinogenicity studies have been conducted with cefepime. In chromosomal aberration studies, cefepime was positive for clastogenicity in primary human lymphocytes, but negative in Chinese hamster ovary cells. In other in vitro assays (bacterial and mammalian cell mutation, DNA repair in primary rat hepatocytes, and sister chromatid exchange in human lymphocytes), cefepime was negative for genotoxic effects. Moreover, in vivo assessments of cefepime in mice (2 chromosomal aberration and 2 micronucleus studies) were negative for clastogenicity. No untoward effects on fertility were observed in rats when cefepime was administered subcutaneously at doses up to 1,000 mg/kg/day (1.6 times the recommended maximum human dose based on body surface area).

17 PATIENT COUNSELING INFORMATION Counsel patients that antibacterial drugs including cefepime for injection should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When cefepime for injection is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by cefepime for injection or other antibacterial drugs in the future. Diarrhea is a common problem caused by antibacterial drugs, which usually ends when the antibacterial drug is discontinued. Inform patient that they may develop watery and bloody stools (with or without stomach cramps and fever) during treatment and as late as two or more months after having taken the last dose of the antibacterial drug. Inform patients that they should contact their physician as soon as possible if this occurs. Advise patients of neurological adverse events that could occur with cefepime for injection use. Instruct patients or their caregivers to inform their healthcare provider at once of any neurological signs and symptoms, including encephalopathy (disturbance of consciousness including confusion, hallucinations, stupor, and coma), aphasia (disturbance of speaking and understanding spoken and written language), myoclonus, seizures and nonconvulsive status epilepticus, for immediate treatment, dosage adjustment, or discontinuation of cefepime for injection.

14 CLINICAL STUDIES 14.1 Febrile Neutropenic Patients The safety and efficacy of empiric cefepime monotherapy of febrile neutropenic patients have been assessed in two multicenter, randomized trials comparing cefepime monotherapy (at a dose of 2 g intravenously every 8 hours) to ceftazidime monotherapy (at a dose of 2 g intravenously every 8 hours). These studies comprised 317 evaluable patients. Table 10 describes the characteristics of the evaluable patient population. Table 10: Demographics of Evaluable Patients (First Episodes Only) Cefepime Ceftazidime Total 164 153 Median age (yr) 56 (range, 18 to 82) 55 (range, 16 to 84) Male 86 (52%) 85 (56%) Female 78 (48%) 68 (44%) Leukemia 65 (40%) 52 (34%) Other hematologic malignancies 43 (26%) 36 (24%) Solid tumor 54 (33%) 56 (37%) Median ANC nadir (cells/microliter) 20 (range, 0 to 500) 20 (range, 0 to 500) Median duration of neutropenia (days) 6 (range, 0 to 39) 6 (range, 0 to 32) Indwelling venous catheter 97 (59%) 86 (56%) Prophylactic antibacterial drugs 62 (38%) 64 (42%) Bone marrow graft 9 (5%) 7 (5%) SBP less than 90 mm Hg at entry 7 (4%) 2 (1%) ANC = absolute neutrophil count; SBP – systolic blood pressure Table 11 describes the clinical response rates observed. For all outcome measures, cefepime was therapeutically equivalent to ceftazidime. Table 11: Pooled Response Rates for Empiric Therapy of Febrile Neutropenic Patients % Response Cefepime Ceftazidime Outcome Measures (n=164) (n=153) Primary episode resolved with no treatment modification, no new febrile episodes or infection, and oral antibacterial drugs allowed for completion of treatment 51 55 Primary episode resolved with no treatment modification, no new febrile episodes or infection and no post-treatment oral antibacterial drugs 34 39 Survival, any treatment modification allowed 93 97 Primary episode resolved with no treatment modification and oral antibacterial drugs allowed for completion of treatment 62 67 Primary episode resolved with no treatment modification and no post-treatment oral antibacterial drugs 46 51 Insufficient data exist to support the efficacy of cefepime monotherapy in patients at high risk for severe infection (including patients with a history of recent bone marrow transplantation, with hypotension at presentation, with an underlying hematologic malignancy, or with severe or prolonged neutropenia). No data are available in patients with septic shock. 14.2 Complicated Intra-abdominal Infections Patients hospitalized with complicated intra-abdominal infections participated in a randomized, double-blind, multicenter trial comparing the combination of cefepime (2 g every 12 hours) plus intravenous metronidazole (500 mg every 6 hours) versus imipenem/cilastatin (500 mg every 6 hours) for a maximum duration of 14 days of therapy. The study was designed to demonstrate equivalence of the two therapies. The primary analyses were conducted on the population consisting of those with a surgically confirmed complicated infection, at least one pathogen isolated pretreatment, at least 5 days of treatment, and a 4 to 6 week follow-up assessment for cured patients. Subjects in the imipenem/cilastatin arm had higher APACHE II scores at baseline. The treatment groups were otherwise generally comparable with regard to their pretreatment characteristics. The overall clinical cure rate among the primary analysis patients was 81% (51 cured/63 evaluable patients) in the cefepime plus metronidazole group and 66% (62/94) in the imipenem/cilastatin group. The observed differences in efficacy may have been due to a greater proportion of patients with high APACHE II scores in the imipenem/cilastatin group.

8.5 Geriatric Use Of the more than 6,400 adults treated with cefepime for injection in clinical studies, 35% were 65 years or older while 16% were 75 years or older. When geriatric patients received the usual recommended adult dose, clinical efficacy and safety were comparable to clinical efficacy and safety in non-geriatric adult patients. Serious adverse events have occurred in geriatric patients with renal insufficiency given unadjusted doses of cefepime, including life-threatening or fatal occurrences of the following: encephalopathy, myoclonus, and seizures [see Warnings and Precautions ( 5.2 ), Adverse Reactions ( 6.2 )] . This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and renal function should be monitored [see Clinical Pharmacology ( 12.3 ), Warnings and Precautions ( 5.2 ), Dosage and Administration ( 2.3 )] .

8.4 Pediatric Use The safety and effectiveness of cefepime in the treatment of uncomplicated and complicated urinary tract infections (including pyelonephritis), uncomplicated skin and skin structure infections, pneumonia, and as empiric therapy for febrile neutropenic patients have been established in the age groups 2 months up to 16 years. Use of cefepime for injection in these age groups is supported by evidence from adequate and well-controlled studies of cefepime in adults with additional pharmacokinetic and safety data from pediatric trials [see Clinical Pharmacology ( 12.3 )] . Safety and effectiveness in pediatric patients below the age of 2 months have not been established. There are insufficient clinical data to support the use of cefepime for injection in pediatric patients for the treatment of serious infections in the pediatric population where the suspected or proven pathogen is H. influenzae type b. In those patients in whom meningeal seeding from a distant infection site or in whom meningitis is suspected or documented, an alternate agent with demonstrated clinical efficacy in this setting should be used.

8.1 Pregnancy Risk Summary There are no cases of cefepime exposure during pregnancy reported from postmarketing experience or from clinical trials. Available data from published observational studies and case reports over several decades with cephalosporin use in pregnant women have not established drug-associated risks of major birth defects, miscarriage or adverse maternal or fetal outcomes ( see Data ). Cefepime was not associated with adverse developmental outcomes in rats, mice, or rabbits when administered parenterally during organogenesis. The doses used in these studies were 1.6 (rats), approximately equal to (mice), and 0.3 times (rabbits) the recommended maximum human dose ( see Data ). The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Human Data While available studies cannot definitively establish the absence of risk, published data from case control studies and case reports over several decades have not identified an association with cephalosporin use during pregnancy and major birth defects, miscarriage, or other adverse maternal or fetal outcomes. Available studies have methodologic limitations, including small sample size, retrospective data collection, and inconsistent comparator groups. Animal Data Cefepime was not embryocidal and did not cause fetal malformations when administered parenterally during the period of organogenesis to rats at doses up to 1000 mg/kg/day, to mice at doses up to 1200 mg/kg/day, or to rabbits at doses up to 100 mg/kg/day. These doses are 1.6 times (rats), approximately equal to (mice), and 0.3 times (rabbits) the maximum recommended clinical dose based on body surface area.

These doses are 1.6 times (rats), approximately equal to (mice), and 0.3 times (rabbits) the maximum recommended clinical dose based on body surface area. 8.2 Lactation Risk Summary Cefepime is present in human breast milk at low concentrations (approximately 0.5 mcg/mL) following a single intravenous dose of 1000 mg. A nursing infant consuming approximately 1000 mL of human milk per day would receive approximately 0.5 mg of cefepime per day ( see Data ). There is no information regarding the effects of cefepime on the breastfed infant or on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for cefepime and any potential adverse effects on the breastfed child from cefepime or from the underlying maternal condition. Data A pharmacokinetic study was conducted in 9 healthy lactating women to evaluate the concentrations of cefepime in plasma and breast milk following a single intravenous dose of 1000 mg. The mean breast milk concentrations of cefepime during the first 8 hours post-dose were approximately 0.5 mcg/mL and then declined and became undetectable between 12- and 24-hours post-dose. The mean cumulative breast milk excretion of cefepime over 24 hours was 0.01% of the administered dose. The pharmacokinetics of cefepime are similar between lactating and non-lactating women. 8.4 Pediatric Use The safety and effectiveness of cefepime in the treatment of uncomplicated and complicated urinary tract infections (including pyelonephritis), uncomplicated skin and skin structure infections, pneumonia, and as empiric therapy for febrile neutropenic patients have been established in the age groups 2 months up to 16 years.
