dalbavancin 500 MG Injection [Dalvance]

INDICATIONS AND USAGE Dalbavancin for Injection is a lipoglycopeptide antibacterial indicated for the treatment of adult and pediatric patients with acute bacterial skin and skin structure infections (ABSSSI) caused by designated susceptible strains of Gram-positive microorganisms. ( 1.1 ) To reduce the development of drug-resistant bacteria and maintain the effectiveness of Dalbavancin for Injection and other antibacterial drugs, Dalbavancin for Injection 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 Acute Bacterial Skin and Skin Structure Infections Dalbavancin for Injection is indicated for the treatment of adult and pediatric patients with acute bacterial skin and skin structure infections (ABSSSI) caused by designated susceptible strains of the following Gram-positive microorganisms: Staphylococcus aureus (including methicillin-susceptible and methicillin-resistant isolates), Streptococcus pyogenes , Streptococcus agalactiae , Streptococcus dysgalactiae , Streptococcus anginosus group (including S. anginosus , S. intermedius , S . constellatus ) and Enterococcus faecalis (vancomycin susceptible isolates). 1.2 Usage To reduce the development of drug-resistant bacteria and maintain the effectiveness of Dalbavancin for Injection and other antibacterial agents, Dalbavancin 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.

DOSAGE AND ADMINISTRATION Dosage in Adult Patients ( 2.1 , 2.3 ): Estimated Creatinine Clearance ( C L cr) Single- Dose Regimen 30 mL/min and above or on regular hemodialysis 1,500 mg Less than 30 mL/min and not on regular hemodialysis 1,125 mg Administer by intravenous infusion over 30 minutes ( 2.1 , 2.4 ) See Full Prescribing Information for instructions on reconstitution of lyophilized powder and preparation of injection ( 2.4 ) Dosage in Pediatric Patients with CLcr 30 mL/min/1.73m 2 and above ( 2.2 ) Age Range Dosage (Single-Dose Regimen) Birth to less than 6 years 22.5 mg/kg (maximum of 1,500 mg) 6 to less than 18 years 18 mg/kg (maximum of 1,500 mg) Dosage adjustment in pediatric patients with CLcr less than 30 mL/min has not been studied. 2.1 Recommended Dos ag e Regimen in Adult Patients with CLcr 30 mL/min and Above The recommended dosage regimen of dalbavancin for injection in adult patients with CLcr 30 mL/min and above is 1,500 mg, administered as a single-dose regimen. Administer dalbavancin for injection over 30 minutes by intravenous infusion. For adult patients with CLcr less than 30 mL/min, dosage adjustment is required [see Dosage and Administration ( 2.3 ) and Clinical Pharmacology ( 12.3 ) ] . 2.2 Recommended Dosage Regimen in Pediatric Patients with CLcr 30 mL/min/ 1.73m 2 and Abov e The recommended dosage regimen of dalbavancin for injection in pediatric patients with CLcr 30 mL/min/1.73m 2 and above is a single-dose regimen based on the age and weight of the pediatric patient ( Table 1 ). Administer dalbavancin for injection over 30 minutes by intravenous infusion. There is insufficient information to recommend dosage adjustment for pediatric patients younger than 18 years with CLcr less than 30 mL/min/1.73m 2 [see Use in Specific Populations ( 8.4 ) and Clinical Pharmacology ( 12.3 )] . Table 1. Dosage of Dalbavancin for Injection in Pediatric Patients with CLcr* 30 mL/min/1.73m 2 and above Age Range Dosage (Single-Dose Regimen) Birth to less than 6 years 22.5 mg/kg (maximum 1,500 mg) 6 to less than 18 years 18 mg/kg (maximum 1,500 mg) *Estimate CLcr or glomerular filtration rate (GFR) using an age-appropriate equation accepted for pediatric patients (birth to less than 18 years old) to define renal function impairment. 2.3 Dosage Adjustments in Adult Patients with CLcr less than 30 mL/min In adult patients with renal impairment whose known CLcr is less than 30 mL/min and who are not receiving regularly scheduled hemodialysis, the recommended dosage regimen of dalbavancin for injection is 1,125 mg, administered as a single-dose regimen. No dosage adjustment is recommended for adult patients receiving regularly scheduled hemodialysis, and dalbavancin for injection can be administered without regard to the timing of hemodialysis [see Use in Specific Populations ( 8.6 ) and Clinical Pharmacology ( 12.3 )] . 2.4 Preparation and Administration Dalbavancin for injection must be reconstituted with either Sterile Water for Injection, USP, or 5% Dextrose Injection, USP, and subsequently diluted only with 5% Dextrose Injection, USP, to a final concentration of 1 mg per mL to 5 mg per mL. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Reconstitution Dalbavancin for injection must be reconstituted under aseptic conditions, using 25 mL of either Sterile Water for Injection, USP, or 5% Dextrose Injection, USP, for each 500 mg vial. To avoid foaming, alternate between gentle swirling and inversion of the vial until its contents are completely dissolved. Do not shake. The reconstituted vial contains 20 mg per mL dalbavancin as a clear, colorless to yellow solution. Reconstituted vials may be stored either refrigerated at 2° to 8°C (36° to 46°F), or at controlled room temperature 20° to 25°C (68° to 77°F). Do not freeze. Dilution Adult Patients Aseptically transfer the required dose of reconstituted dalbavancin for injection solution from the vial(s) to an intravenous bag or bottle containing 5% Dextrose Injection, USP . The diluted solution must have a final dalbavancin concentration of 1 mg per mL to 5 mg per mL. Discard any unused portion of the reconstituted solution. Pediatric Patients For pediatric patients, the dose of dalbavancin for injection will vary according to the age and weight of the child up to a maximum of 1,500 mg [see Dosage and Administration ( 2.2 )] . Aseptically transfer the required dose of reconstituted dalbavancin for injection solution, based on the child’s weight, from the vial(s) to an intravenous bag or bottle containing 5% Dextrose Injection, USP. The diluted solution must have a final dalbavancin concentration of 1 mg per mL to 5 mg per mL. Discard any unused portion of the reconstituted solution. Once diluted into an intravenous bag or bottle as described above, dalbavancin for injection may be stored either refrigerated at 2° to 8°C (36° to 46°F) or at a controlled room temperature of 20° to 25°C (68° to 77°F). Do not freeze. The total time from reconstitution to dilution to administration should not exceed 48 hours. Like all parenteral drug products, diluted dalbavancin for injection should be inspected visually for particulate matter prior to infusion. If particulate matter is identified, do not use. Administration After reconstitution and dilution, administer dalbavancin for injection via intravenous infusion, using a total infusion time of 30 minutes. Do not co-infuse dalbavancin for injection with other medications or electrolytes. Saline-based infusion solutions may cause precipitation and should not be used. The compatibility of reconstituted dalbavancin for injection with intravenous medications, additives, or substances other than 5% Dextrose Injection, USP has not been established. If a common intravenous line is being used to administer other drugs in addition to dalbavancin for injection, the line should be flushed before and after each dalbavancin for injection infusion with 5% Dextrose Injection, USP.

WARNINGS AND PRECAUTIONS • Serious hypersensitivity (anaphylactic) and skin reactions have been reported in patients treated with dalbavancin for injection. If an allergic reaction occurs, discontinue treatment with dalbavancin for injection and institute appropriate therapy for the allergic reaction. Carefully monitor patients with known hypersensitivity to glycopeptides. ( 5.1 ) • Rapid intravenous infusion of dalbavancin for injection can cause flushing of the upper body, urticaria, pruritus, rash, and/or back pain. Stopping or slowing the infusion may result in cessation of these reactions. ( 5.2 ) • Alanine Aminotransferase (ALT) elevations with dalbavancin for injection treatment were reported in clinical trials. ( 5.3 , 6.1 ) • Clostridioides difficile -associated diarrhea (CDAD) has been reported with nearly all systemic antibacterial agents, including dalbavancin for injection. Evaluate if diarrhea occurs. ( 5.4 ) 5.1 Hypersensitivity Reactions Serious hypersensitivity (anaphylactic) and skin reactions have been reported in patients treated with dalbavancin for injection. If an allergic reaction to dalbavancin for injection occurs, discontinue treatment with dalbavancin for injection and institute appropriate therapy for the allergic reaction. Before using dalbavancin for injection, inquire carefully about previous hypersensitivity reactions to other glycopeptides. Due to the possibility of cross-sensitivity, carefully monitor for signs of hypersensitivity during treatment with dalbavancin for injection in patients with a history of glycopeptide allergy [see Patient Counseling Information ( 17 )] . 5.2 Infusion-Related Reactions Dalbavancin for injection is administered via intravenous infusion, using a total infusion time of 30 minutes to minimize the risk of infusion-related reactions. Rapid intravenous infusions of dalbavancin for injection can cause flushing of the upper body, urticaria, pruritus, rash, and/or back pain. Stopping or slowing the infusion may result in cessation of these reactions. 5.3 Hepatic Effects In Phase 2 and 3 clinical trials, more dalbavancin for injection than comparator-treated subjects with normal baseline transaminase levels had post-baseline alanine aminotransferase (ALT) elevation greater than 3 times the upper limit of normal (ULN). Overall, abnormalities in liver tests (ALT, AST, bilirubin) were reported with similar frequency in the dalbavancin for injection and comparator arms [see Adverse Reactions ( 6.1 )]. 5.4 Clostridioides difficile -Associated Diarrhea Clostridioides difficile -associated diarrhea (CDAD) has been reported in users of nearly all systemic antibacterial drugs, including dalbavancin for injection, with severity ranging from mild diarrhea to fatal colitis. Treatment with antibacterial agents can alter the normal flora of the colon, and may permit 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 antibacterial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibacterial use. Careful medical history is necessary because CDAD has been reported to occur more than 2 months after the administration of antibacterial agents. If CDAD is suspected or confirmed, ongoing antibacterial use not directed against C. difficile should be discontinued, if possible. Appropriate measures such as fluid and electrolyte management, protein supplementation, antibacterial treatment of C. difficile , and surgical evaluation should be instituted as clinically indicated. 5.5 Development of Drug-Resistant Bacteria Prescribing dalbavancin for injection in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.
