Daptomycin for Injection is a lipopeptide antibacterial indicated for the treatment of: • Complicated skin and skin structure infections (cSSSI) in adult patients ( 1.1 ) and, • Staphylococcus aureus bloodstream infections (bacteremia), in adult patients including those with right-sided infective endocarditis, ( 1.2 ) Limitations of Use: • This Daptomycin for Injection product is not approved for use in pediatric patients. ( 1.3 ) • Daptomycin for Injection is not indicated for the treatment of pneumonia. ( 1.3 ) • Daptomycin for Injection is not indicated for the treatment of left-sided infective endocarditis due to S. aureus . ( 1.3 ) • Daptomycin for Injection is not recommended in pediatric patients younger than one year of age due to the risk of potential effects on muscular, neuromuscular, and/or nervous systems (either peripheral and/or central) observed in neonatal dogs. ( 1.3 ) To reduce the development of drug-resistant bacteria and maintain the effectiveness of Daptomycin for Injection and other antibacterial drugs, Daptomycin for Injection should be used to treat or prevent infections that are proven or strongly suspected to be caused by bacteria. ( 1.4 ) 1.1 Complicated Skin and Skin Structure Infections (cSSSI) Daptomycin for Injection is indicated for the treatment of adult patients with complicated skin and skin structure infections (cSSSI) caused by susceptible isolates of the following Gram-positive bacteria: Staphylococcus aureus (including methicillin-resistant isolates), Streptococcus pyogenes, Streptococcus agalactiae, Streptococcus dysgalactiae subsp. equisimilis, and Enterococcus faecalis (vancomycin-susceptible isolates only). 1.2 Staphylococcus aureus Bloodstream Infections (Bacteremia) in Adult Patients, Including Those with Right-Sided Infective Endocarditis, Caused by Methicillin-Susceptible and Methicillin-Resistant Isolates Daptomycin for Injection is indicated for the treatment of adult patients with Staphylococcus aureus bloodstream infections (bacteremia), including adult patients with right-sided infective endocarditis, caused by methicillin-susceptible and methicillin-resistant isolates. 1.3 Limitations of Use This Daptomycin for Injection product is not approved for use in pediatric patients [see Use in Specific Populations (8.4) ] . Daptomycin for Injection is not indicated for the treatment of pneumonia. Daptomycin for Injection is not indicated for the treatment of left-sided infective endocarditis due to S. aureus . The clinical trial of daptomycin for injection in adult patients with S. aureus bloodstream infections included limited data from patients with left-sided infective endocarditis; outcomes in these patients were poor [see Clinical Studies (14.2) ] . Daptomycin for Injection has not been studied in patients with prosthetic valve endocarditis. Daptomycin for Injection is not recommended in pediatric patients younger than 1 year of age due to the risk of potential effects on muscular, neuromuscular, and/or nervous systems (either peripheral and/or central) observed in neonatal dogs [see Warnings and Precautions (5.7) and Nonclinical Toxicology (13.2) ] . 1.4 Usage Appropriate specimens for microbiological examination should be obtained in order to isolate and identify the causative pathogens and to determine their susceptibility to daptomycin. To reduce the development of drug-resistant bacteria and maintain the effectiveness of Daptomycin for Injection and other antibacterial drugs, Daptomycin 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 is available, it 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. Empiric therapy may be initiated while awaiting test results.

Adult Patients • Administer to adult patients intravenously in 0.9% sodium chloride, either by injection over a 2-minute period or by infusion over a 30-minute period. ( 2.1 , 2.5 ) • Recommended dosage regimen for adult patients ( 2.2 , 2.3 , 2.4 ): Creatinine Clearance (CrCl) Dosage Regimen cSSSI For 7 to 14 days S. aureus Bacteremia For 2 to 6 weeks ≥30 mL/min 4 mg/kg once every 24 hours 6 mg/kg once every 24 hours <30 mL/min, including hemodialysis and CAPD 4 mg/kg once every 48 hours Administered following hemodialysis on hemodialysis days. 6 mg/kg once every 48 hours • There are other formulations of daptomycin that have differences concerning storage and reconstitution. Carefully follow the reconstitution and storage procedures described in this labeling. ( 2.5 ) • Do not use in conjunction with ReadyMED ® elastomeric infusion pumps in adult patients. ( 2.5 ) 2.1 Important Administration Duration Instructions Adults Administer the appropriate volume of the reconstituted Daptomycin for Injection (concentration of 50 mg/mL) to adult patients intravenously either by injection over a two (2) minute period or by intravenous infusion over a thirty (30) minute period [see Dosage and Administration (2.2 , 2.3 , 2.5) ] . 2.2 Dosage in Adults for cSSSI Administer Daptomycin for Injection 4 mg/kg to adult patients intravenously in 0.9% sodium chloride injection once every 24 hours for 7 to 14 days. 2.3 Dosage in Adult Patients with Staphylococcus aureus Bloodstream Infections (Bacteremia), Including Those with Right-Sided Infective Endocarditis, Caused by Methicillin-Susceptible and Methicillin-Resistant Isolates Administer Daptomycin for Injection 6 mg/kg to adult patients intravenously in 0.9% sodium chloride injection once every 24 hours for 2 to 6 weeks. There are limited safety data for the use of daptomycin for injection for more than 28 days of therapy. In the Phase 3 trial, there were a total of 14 adult patients who were treated with daptomycin for injection for more than 28 days. 2.4 Dosage in Patients with Renal Impairment Adult Patients: No dosage adjustment is required in adult patients with creatinine clearance (CL CR ) greater than or equal to 30 mL/min. The recommended dosage regimen for Daptomycin for Injection in adult patients with CL CR less than 30 mL/min, including adult patients on hemodialysis or continuous ambulatory peritoneal dialysis (CAPD), is 4 mg/kg (cSSSI) or 6 mg/kg ( S. aureus bloodstream infections) once every 48 hours (Table 1). When possible, Daptomycin for Injection should be administered following the completion of hemodialysis on hemodialysis days [see Warnings and Precautions (5.2 , 5.10) , Use in Specific Populations (8.6) , and Clinical Pharmacology (12.3) ] . Table 1: Recommended Dosage of Daptomycin for Injection in Adult Patients Creatinine Clearance (CL CR ) Dosage Regimen in Adults cSSSI S. aureus Bloodstream Infections Greater than or equal to 30 mL/min 4 mg/kg once every 24 hours 6 mg/kg once every 24 hours Less than 30 mL/min, including hemodialysis and CAPD 4 mg/kg once every 48 hours When possible, administer Daptomycin for Injection following the completion of hemodialysis on hemodialysis days. 6 mg/kg once every 48 hours Pediatric Patients: The dosage regimen for Daptomycin for Injection in pediatric patients with renal impairment has not been established. 2.5 Preparation and Administration of Daptomycin for Injection There are other formulations of daptomycin that have differences concerning reconstitution and storage. Carefully follow the reconstitution and storage procedures described in this labeling. Reconstitution of Daptomycin for Injection Vial Daptomycin for Injection is supplied in single-dose vials, each containing 350 mg or 500 mg daptomycin as a sterile, lyophilized powder. The contents of a Daptomycin for Injection vial should be reconstituted, using aseptic technique, to 50 mg/mL as follows: • To minimize foaming, AVOID vigorous agitation or shaking of the vial during or after reconstitution. • Remove the polypropylene flip-off cap from the Daptomycin for Injection vial to expose the central portion of the rubber stopper. Wipe the top of the rubber stopper with an alcohol swab or other antiseptic solution and allow to dry. • Pierce the center of the rubber stopper with the syringe needle and GENTLY inject 10 mL of 0.9% sodium chloride injection directly over the Daptomycin for Injection 500 mg drug product or 7 mL of 0.9% sodium chloride injection directly over the Daptomycin for Injection 350 mg drug product. Release the syringe plunger and allow the syringe plunger to equalize the pressure before removing the syringe from the vial. • Hold the vial by the vial neck, tilt the vial and swirl vial contents until the product is completely reconstituted. Administration Instructions Parenteral drug products should be inspected visually for particulate matter prior to administration. Slowly remove reconstituted liquid (concentration of 50 mg daptomycin/mL) from the vial using a beveled sterile needle that is 21 gauge or smaller in diameter. Administer as an intravenous injection or infusion as described below: Adults Intravenous Injection over a period of 2 minutes • For intravenous (IV) injection over a period of 2 minutes in adult patients only: Administer the appropriate volume of the reconstituted Daptomycin for Injection (concentration of 50 mg/mL). Intravenous Infusion over a period of 30 minutes • For IV infusion over a period of 30 minutes in adult patients: The appropriate volume of the reconstituted Daptomycin for Injection (concentration of 50 mg/mL) should be further diluted, using aseptic technique, into a 50 mL IV infusion bag containing 0.9% sodium chloride injection. No preservative or bacteriostatic agent is present in this product. Aseptic technique must be used in the preparation of final IV solution. Do not exceed the In-Use storage conditions of the reconstituted and diluted solutions of Daptomycin for Injection described below. Discard unused portions of Daptomycin for Injection. In-Use Storage Conditions for Daptomycin for Injection Once Reconstituted in Acceptable Intravenous Diluents Stability studies have shown that the reconstituted solution is stable in the vial for 12 hours at room temperature under normal room light and up to 48 hours if stored under refrigeration protected from light at 2°C to 8°C (36°F to 46°F). The diluted solution is stable in the infusion bag for 12 hours under normal room light at room temperature and 48 hours (Lactated Ringer's) or 10 days (0.9% sodium chloride) if stored under refrigeration protected from light. For Lactated Ringer's diluent, the combined storage time (reconstituted solution in vial and diluted solution in infusion bag) should not exceed 12 hours at room temperature or 48 hours under refrigeration. For 0.9% sodium chloride diluent, the combined storage time (reconstituted solution in vial and diluted solution in infusion bag) should not exceed 12 hours at room temperature or 10 days under refrigeration. 2.6 Compatible Intravenous Solutions Daptomycin for Injection is compatible with 0.9% sodium chloride injection for reconstitution. Reconstituted Daptomycin for Injection can be diluted with 0.9% sodium chloride injection or Lactated Ringer's injection. 2.7 Incompatibilities Daptomycin for injection is not compatible with dextrose-containing diluents. Daptomycin for Injection should not be used in conjunction with ReadyMED ® elastomeric infusion pumps. Stability studies of daptomycin for injection solutions stored in ReadyMED ® elastomeric infusion pumps identified an impurity (2-mercaptobenzothiazole) leaching from this pump system into the daptomycin for injection solution. Because only limited data are available on the compatibility of daptomycin for injection with other IV substances, additives and other medications should not be added to Daptomycin for Injection single-dose vials or infusion bags, or infused simultaneously with Daptomycin for Injection through the same IV line. If the same IV line is used for sequential infusion of different drugs, the line should be flushed with a compatible intravenous solution before and after infusion with Daptomycin for Injection.

Daptomycin for Injection is contraindicated in patients with known hypersensitivity to daptomycin [see Warnings and Precautions (5.1) ] . Known hypersensitivity to daptomycin ( 4 )

The following adverse reactions are described, or described in greater detail, in other sections: • Anaphylaxis/Hypersensitivity Reactions [see Warnings and Precautions (5.1) ] • Myopathy and Rhabdomyolysis [see Warnings and Precautions (5.2) ] • Eosinophilic Pneumonia [see Warnings and Precautions (5.3) ] • Drug Reaction with Eosinophilia and Systemic Symptoms [see Warnings and Precautions (5.4) ] • Tubulointerstitial Nephritis [see Warnings and Precautions (5.5) ] • Peripheral Neuropathy [see Warnings and Precautions (5.6) ] • Increased International Normalized Ratio (INR)/Prolonged Prothrombin Time [see Warnings and Precautions (5.11) and Drug Interactions (7.2) ] • Adult cSSSI Patients : The most common adverse reactions that occurred in ≥2% of adult cSSSI patients receiving daptomycin for injection 4 mg/kg were diarrhea, headache, dizziness, rash, abnormal liver function tests, elevated creatine phosphokinase (CPK), urinary tract infections hypotension, and dyspnea. ( 6.1 ) • Adult S. aureus bacteremia/endocarditis Patients: The most common adverse reactions that occurred in ≥5% of S. aureus bacteremia/endocarditis patients receiving daptomycin for injection 6 mg/kg were sepsis, bacteremia, abdominal pain, chest pain, edema, pharyngolaryngeal pain, pruritus, increased sweating, insomnia, elevated CPK, and hypertension.

Clinical Trial Experience in Adult Patients Clinical trials enrolled 1,864 adult patients treated with daptomycin and 1,416 treated with comparator. Complicated Skin and Skin Structure Infection Trials in Adults In Phase 3 complicated skin and skin structure infection (cSSSI) trials in adult patients, daptomycin for injection was discontinued in 15/534 (2.8%) patients due to an adverse reaction, while comparator was discontinued in 17/558 (3.0%) patients. The rates of the most common adverse reactions, organized by body system, observed in adult patients with cSSSI (receiving 4 mg/kg daptomycin) are displayed in Table 4.

Serious Gram-negative infections (including bloodstream infections) were reported in 10/120 (8.3%) daptomycin for injection-treated patients and 0/115 comparator-treated patients. Comparator-treated patients received dual therapy that included initial gentamicin for 4 days. Infections were reported during treatment and during early and late follow-up. Gram-negative infections included cholangitis, alcoholic pancreatitis, sternal osteomyelitis/mediastinitis, bowel infarction, recurrent Crohn's disease, recurrent line sepsis, and recurrent urosepsis caused by a number of different Gram-negative bacteria. The rates of the most common adverse reactions, organized by System Organ Class (SOC), observed in adult patients with S. aureus bacteremia/endocarditis (receiving 6 mg/kg daptomycin) are displayed in Table 5.

These differences were due to lack of therapeutic effectiveness of daptomycin for injection in the treatment of CAP in patients experiencing these adverse events [see Indications and Usage (1.3) ] . Laboratory Changes in Adults Complicated Skin and Skin Structure Infection Trials in Adults In Phase 3 cSSSI trials of adult patients receiving daptomycin for injection at a dose of 4 mg/kg, elevations in CPK were reported as clinical adverse events in 15/534 (2.8%) daptomycin for injection-treated patients, compared with 10/558 (1.8%) comparator-treated patients. Of the 534 patients treated with daptomycin, 1 (0.2%) had symptoms of muscle pain or weakness associated with CPK elevations to greater than 4 times the upper limit of normal (ULN). The symptoms resolved within 3 days and CPK returned to normal within 7 to 10 days after treatment was discontinued [see Warnings and Precautions (5.2) ] . Table 6 summarizes the CPK shifts from Baseline through End of Therapy in the cSSSI adult trials.

Of the 11 daptomycin for injection-treated patients, 4 had prior or concomitant treatment with an HMG-CoA reductase inhibitor. Three of these 11 daptomycin for injection-treated patients discontinued therapy due to CPK elevation, while the one comparator-treated patient did not discontinue therapy [see Warnings and Precautions (5.2) ]. 6.2 Post-Marketing Experience The following adverse reactions have been identified during post-approval use of daptomycin. 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. Blood and lymphatic system disorders: anemia, thrombocytopenia General and administration site conditions: pyrexia Immune System Disorders: anaphylaxis; hypersensitivity reactions, including angioedema, pruritus, hives, shortness of breath, difficulty swallowing, truncal erythema, and pulmonary eosinophilia [see Contraindications (4) and Warnings and Precautions (5.1) ] Infections and Infestations: Clostridioides difficile –associated diarrhea [see Warnings and Precautions (5.8) ] Laboratory Investigations: platelet count decreased Musculoskeletal Disorders: myoglobin increased; rhabdomyolysis (some reports involved patients treated concurrently with daptomycin and HMG-CoA reductase inhibitors) [see Warnings and Precautions (5.2) , Drug Interactions (7.1) , and Clinical Pharmacology (12.3) ] Respiratory, Thoracic, and Mediastinal Disorders: cough, eosinophilic pneumonia, organizing pneumonia [see Warnings and Precautions (5.3) ] Nervous System Disorders: peripheral neuropathy [see Warnings and Precautions (5.6) ] Skin and Subcutaneous Tissue Disorders: serious skin reactions, including drug reaction with eosinophilia and systemic symptoms (DRESS), vesiculobullous rash (with or without mucous membrane involvement, including Stevens-Johnson syndrome [SJS] and toxic epidermal necrolysis [TEN]), and acute generalized exanthematous pustulosis [see Warnings and Precautions (5.4) ] Gastrointestinal Disorders: nausea, vomiting Metabolic and Nutritional Disorders: hyperkalemia Renal and urinary disorders: acute kidney injury, renal insufficiency, renal failure, and tubulointerstitial nephritis (TIN) [see Warnings and Precautions (5.5) ] Special Senses: visual disturbances

7.1 HMG-CoA Reductase Inhibitors In healthy adult subjects, concomitant administration of daptomycin and simvastatin had no effect on plasma trough concentrations of simvastatin, and there were no reports of skeletal myopathy [see Clinical Pharmacology (12.3) ]. However, inhibitors of HMG-CoA reductase may cause myopathy, which is manifested as muscle pain or weakness associated with elevated levels of creatine phosphokinase (CPK). In the adult Phase 3 S. aureus bacteremia/endocarditis trial, some patients who received prior or concomitant treatment with an HMG-CoA reductase inhibitor developed elevated CPK [see Adverse Reactions (6.1) ]. Experience with the co-administration of HMG-CoA reductase inhibitors and daptomycin in patients is limited; therefore, consideration should be given to suspending use of HMG-CoA reductase inhibitors temporarily in patients receiving Daptomycin for Injection. 7.2 Drug-Laboratory Test Interactions Clinically relevant plasma concentrations of daptomycin have been observed to cause a significant concentration-dependent false prolongation of prothrombin time (PT) and elevation of International Normalized Ratio (INR) when certain recombinant thromboplastin reagents are utilized for the assay. The possibility of an erroneously elevated PT/INR result due to interaction with a recombinant thromboplastin reagent may be minimized by drawing specimens for PT or INR testing near the time of trough plasma concentrations of daptomycin. However, sufficient daptomycin concentrations may be present at trough to cause interaction. If confronted with an abnormally high PT/INR result in a patient being treated with daptomycin, it is recommended that clinicians: 1. Repeat the assessment of PT/INR, requesting that the specimen be drawn just prior to the next Daptomycin for Injection dose (i.e., at trough concentration). If the PT/INR value obtained at trough remains substantially elevated above what would otherwise be expected, consider evaluating PT/INR utilizing an alternative method. 2. Evaluate for other causes of abnormally elevated PT/INR results.
