eravacycline 100 MG Injection [Xerava]

INDICATIONS AND USAGE XERAVA is a tetracycline class antibacterial indicated for the treatment of complicated intra‑abdominal infections in patients 18 years of age and older. ( 1.1 ) Limitations of Use XERAVA is not indicated for the treatment of complicated urinary tract infections (cUTI). ( 1.1 ) To reduce the development of drug-resistant bacteria and maintain the effectiveness of XERAVA and other antibacterial drugs, XERAVA should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. ( 1.2 ) 1.1 Complicated Intra-abdominal Infections XERAVA is indicated for the treatment of complicated intra‑abdominal infections (cIAI) caused by susceptible microorganisms: Escherichia coli, Klebsiella pneumoniae, Citrobacter freundii, Enterobacter cloacae, Klebsiella oxytoca, Enterococcus faecalis, Enterococcus faecium, Staphylococcus aureus, Streptococcus anginosus group, Clostridium perfringens , Bacteroides species, and Parabacteroides distasonis in patients 18 years or older [see Microbiology ( 12.4 ) and Clinical Studies ( 14.1 )]. Limitations of Use XERAVA is not indicated for the treatment of complicated urinary tract infections (cUTI) [see Clinical Studies ( 14.2 )] . 1.2 Usage To reduce the development of drug-resistant bacteria and maintain the effectiveness of XERAVA and other antibacterial drugs, XERAVA 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.

DOSAGE AND ADMINISTRATION Administer XERAVA for injection 1 mg/kg by intravenous infusion over approximately 60 minutes every 12 hours for a total duration of 4 to 14 days. ( 2.1 ) Severe Hepatic Impairment (Child Pugh C): 1 mg/kg XERAVA every 12 hours on Day 1, then 1 mg/kg every 24 hours starting on Day 2 for a total duration of 4 to 14 days. ( 2.2 ) Concomitant Use of a Strong Cytochrome P450 (CYP) Isoenzyme 3A Inducer: 1.5 mg/kg XERAVA every 12 hours for a total duration of 4 to 14 days. ( 2.3 ) See full prescribing information for the preparation of XERAVA. ( 2.4 ) 2.1 Recommended Adult Dosage The recommended dose regimen of XERAVA is 1 mg/kg every 12 hours. Administer intravenous infusions of XERAVA over approximately 60 minutes every 12 hours. The recommended duration of treatment with XERAVA for cIAI is 4 to 14 days. The duration of therapy should be guided by the severity and location of infection and the patient's clinical response. 2.2 Dosage Modifications in Patients with Hepatic Impairment In patients with severe hepatic impairment (Child Pugh C), administer XERAVA 1 mg/kg every 12 hours on Day 1 followed by XERAVA 1 mg/kg every 24 hours starting on Day 2 for a total duration of 4 to 14 days. No dosage adjustment is warranted in patients with mild to moderate hepatic impairment (Child Pugh A and Child Pugh B) [see Use in Specific Populations ( 8.6 ) and Clinical Pharmacology ( 12.3 )]. 2.3 Dosage Modifications in Patients with Concomitant Use of a Strong Cytochrome P450 (CYP) Isoenzyme 3A Inducer With concomitant use of a strong CYP3A inducer, administer XERAVA 1.5 mg/kg every 12 hours for a total duration of 4 to 14 days. No dosage adjustment is warranted in patients with concomitant use of a weak or moderate CYP3A inducer [see Drug Interactions ( 7.1 ) and Clinical Pharmacology ( 12.3 )]. 2.4 Preparation and Administration XERAVA is for intravenous infusion only. Each vial is for a single dose only. Preparation XERAVA is supplied as a sterile yellow to orange dry powder in a single-dose vial that must be reconstituted and further diluted prior to intravenous infusion as outlined below. XERAVA does not contain preservatives. Aseptic technique must be used for reconstitution and dilution as follows: Calculate the dose of XERAVA based on the patient weight (1 mg/kg actual body weight). Prepare the required dose for intravenous infusion by reconstituting the appropriate number of vials needed. Reconstitute each vial of XERAVA with 5 mL of Sterile Water for Injection, USP or with 5 mL of 0.9% Sodium Chloride Injection, USP, which will deliver the following: XERAVA 50 mg vial will deliver 50 mg (10 mg/mL) of eravacycline (free base equivalents). XERAVA 100 mg vial will deliver 100 mg (20 mg/mL) of eravacycline (free base equivalents). Swirl the vial gently until the powder has dissolved entirely. Avoid shaking or rapid movement as it may cause foaming. The reconstituted XERAVA solution should be a clear, pale yellow to orange solution. Do not use the solution if you notice any particles or the solution is cloudy. Reconstituted solution is not for direct injection. The stability of the solution after reconstitution in the vial has been demonstrated for 1 hour at room temperature (not to exceed 25°C/77°F). If the reconstituted solution in the vial is not diluted in the infusion bag within 1 hour, the reconstituted vial content must be discarded. The reconstituted XERAVA solution is further diluted for intravenous infusion to a target concentration of 0.3 mg/mL, in a 0.9% Sodium Chloride Injection, USP infusion bag before intravenous infusion. To dilute the reconstituted solution, withdraw the full or partial reconstituted vial content from each vial and add it into the infusion bag to generate an infusion solution with a target concentration of 0.3 mg/mL (within a range of 0.2 to 0.6 mg/mL). Do not shake the bag. The diluted solutions must be infused within 12 hours if stored at room temperature (not to exceed 25°C/77°F) or within 8 days if stored refrigerated at 2°C to 8°C (36°F to 46°F). Reconstituted XERAVA solutions and diluted XERAVA infusion solutions should not be frozen. Visually inspect the diluted XERAVA solution for particulate matter and discoloration prior to administration (the XERAVA infusion solution for administration is clear and ranges from light yellow to orange). Discard unused portions of the reconstituted and diluted solution. Administration of the Intravenous Infusion The diluted XERAVA solution is administered as an intravenous infusion over approximately 60 minutes. XERAVA may be administered intravenously through a dedicated line or through a Y-site. If the same intravenous line is used for sequential infusion of several drugs, the line should be flushed before and after infusion of XERAVA with 0.9% Sodium Chloride Injection, USP. 2.5 Drug Compatibilities XERAVA is compatible with 0.9% Sodium Chloride Injection, USP. The compatibility of XERAVA with other drugs and infusion solutions has not been established. XERAVA should not be mixed with other drugs or added to solutions containing other drugs.

WARNINGS AND PRECAUTIONS Hypersensitivity Reactions : Life-threatening hypersensitivity (anaphylactic) reactions have been reported with tetracycline antibacterial drugs, including XERAVA. Avoid use in patients with known hypersensitivity to tetracyclines. ( 5.1 ) Tooth Discoloration and Enamel Hypoplasia : The use of XERAVA during tooth development (last half of pregnancy, infancy and childhood to the age of 8 years) may cause permanent discoloration of the teeth (yellow-gray-brown) and enamel hypoplasia. ( 5.2 , 8.1 , 8.4 ) Inhibition of Bone Growth : The use of XERAVA during the second and third trimester of pregnancy, infancy and childhood up to the age of 8 years may cause reversible inhibition of bone growth. ( 5.3 , 8.1 , 8.4 ) Clostridioides difficile -Associated Diarrhea: Evaluate if diarrhea occurs. ( 5.4 ) 5.1 Hypersensitivity Reactions Life-threatening hypersensitivity (anaphylactic) reactions have been reported with XERAVA [see Adverse Reactions ( 6.1 )] . XERAVA is structurally similar to other tetracycline-class antibacterial drugs and should be avoided in patients with known hypersensitivity to tetracycline- class antibacterial drugs. Discontinue XERAVA if an allergic reaction occurs. 5.2 Tooth Discoloration and Enamel Hypoplasia The use of XERAVA during tooth development (last half of pregnancy, infancy and childhood to the age of 8 years) may cause permanent discoloration of the teeth (yellow-grey-brown). This adverse reaction is more common during long-term use of the tetracycline class drugs, but it has been observed following repeated short-term courses. Enamel hypoplasia has also been reported with tetracycline class drugs. Advise the patient of the potential risk to the fetus if XERAVA is used during the second or third trimester of pregnancy [see Use in Specific Populations ( 8.1 , 8.4 )] . 5.3 Inhibition of Bone Growth The use of XERAVA during the second and third trimester of pregnancy, infancy and childhood up to the age of 8 years may cause reversible inhibition of bone growth. All tetracyclines form a stable calcium complex in any bone-forming tissue. A decrease in fibula growth rate has been observed in premature infants given oral tetracycline in doses of 25 mg/kg every 6 hours. This reaction was shown to be reversible when the drug was discontinued. Advise the patient of the potential risk to the fetus if XERAVA is used during the second or third trimester of pregnancy [see Use in Specific Populations ( 8.1 , 8.4 )] . 5.4 Clostridioides difficile -Associated Diarrhea Clostridioides 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. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile. C. difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibacterial drug use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents. If CDAD is suspected or confirmed, ongoing antibacterial drug use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibacterial drug treatment of C. difficile , and surgical evaluation should be instituted as clinically indicated. 5.5 Tetracycline Class Adverse Reactions XERAVA is structurally similar to tetracycline-class antibacterial drugs and may have similar adverse reactions. Adverse reactions including photosensitivity, fixed drug eruption, 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 XERAVA. Discontinue XERAVA if any of these adverse reactions is suspected. 5.6 Potential for Microbial Overgrowth XERAVA use may result in overgrowth of non-susceptible organisms, including fungi. If such infections occur, discontinue XERAVA and institute appropriate therapy. 5.7 Development of Drug-Resistant Bacteria Prescribing XERAVA 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 [see Indications and Usage ( 1.2 )].
