`
`CUBICIN® (daptomycin for injection)
`
`
`1
`INDICATIONS AND USAGE
`CUBICIN is indicated for the treatment of the infections listed below.
`
`1.1 Complicated Skin and Skin Structure Infections
`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), Including
`Those with Right-Sided Infective Endocarditis, Caused by Methicillin-
`Susceptible and Methicillin-Resistant Isolates
`Staphylococcus aureus bloodstream infections (bacteremia), including those with right-sided
`
`infective endocarditis, caused by methicillin-susceptible and methicillin-resistant isolates.
`
`Limitations of Use
`1.3
`CUBICIN is not indicated for the treatment of pneumonia.
`CUBICIN is not indicated for the treatment of left-sided infective endocarditis due to S. aureus.
`The clinical trial of CUBICIN in patients with S. aureus bloodstream infections included limited
`data from patients with left-sided infective endocarditis; outcomes in these patients were poor
`[see Clinical Trials (14.2)]. CUBICIN has not been studied in patients with prosthetic valve
`
`endocarditis.
`
` Usage
`1.4
`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 CUBICIN
`and other antibacterial drugs, CUBICIN should be used only to treat 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.

`
`DOSAGE AND ADMINISTRATION
`
` Administration Duration
`2.1
`CUBICIN should be administered intravenously either by injection over a two (2) minute period
`or by infusion over a thirty (30) minute period.
`
`2.2 Complicated Skin and Skin Structure Infections
`
`CUBICIN 4 mg/kg should be administered intravenously in 0.9% sodium chloride injection once
`every 24 hours for 7 to 14 days.
`
`2.3 Staphylococcus aureus Bloodstream Infections (Bacteremia), Including
`
`Those with Right-Sided Infective Endocarditis, Caused by Methicillin-
`Susceptible and Methicillin-Resistant Isolates
`CUBICIN 6 mg/kg should be administered 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 CUBICIN for more
`than 28 days of therapy. In the Phase 3 trial, there were a total of 14 patients who were treated
`with CUBICIN for more than 28 days.
`
`Patients with Renal Impairment
`2.4
`
`The recommended dosage regimen for patients with creatinine clearance (CLCR) <30 mL/min,
`including 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, CUBICIN should be administered following the completion of hemodialysis on
`hemodialysis days [see Warnings and Precautions (5.2, 5.8), Use in Specific Populations (8.6),
`
`
`and Clinical Pharmacology (12.3)].

`
`
`Preparation of CUBICIN for Administration
`2.5
`
`CUBICIN is supplied in single-use vials, each containing 500 mg daptomycin as a sterile,
`lyophilized powder. The contents of a CUBICIN vial should be reconstituted, using aseptic
`technique, to 50 mg/mL as follows:
`Note: To minimize foaming, AVOID vigorous agitation or shaking of the vial during or after
`reconstitution.
`
`Reference ID: 3820457
`
`3
`
`
`
`
`
`
`1. Remove the polypropylene flip-off cap from the CUBICIN vial to expose the central
`portion of the rubber stopper.
`2. Slowly transfer 10 mL of 0.9% sodium chloride injection through the center of the
`rubber stopper into the CUBICIN vial, pointing the transfer needle toward the wall of
`
`the vial.
`
`3. Ensure that all of the CUBICIN powder is wetted by gently rotating the vial.
`
`4. Allow the wetted product to stand undisturbed for 10 minutes.
`5. Gently rotate or swirl the vial contents for a few minutes, as needed, to obtain a
`
`completely reconstituted solution.
`
`
`For intravenous (IV) injection over a period of 2 minutes, administer the appropriate volume of
`the reconstituted CUBICIN (concentration of 50 mg/mL).
`For IV infusion over a period of 30 minutes, the appropriate volume of the reconstituted
`CUBICIN (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.
`Parenteral drug products should be inspected visually for particulate matter prior to
`administration.
`No preservative or bacteriostatic agent is present in this product. Aseptic technique must be used
`in the preparation of final IV solution. Stability studies have shown that the reconstituted
`solution is stable in the vial for 12 hours at room temperature and up to 48 hours if stored under
`refrigeration at 2 to 8C (36 to 46F).
`The diluted solution is stable in the infusion bag for 12 hours at room temperature and 48 hours
`if stored under refrigeration. 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.
`CUBICIN vials are for single use only.
`
`2.6 Compatible Intravenous Solutions
`CUBICIN is compatible with 0.9% sodium chloride injection and lactated Ringer’s injection.
`
`Incompatibilities
`2.7
`CUBICIN is not compatible with dextrose-containing diluents.
`CUBICIN should not be used in conjunction with ReadyMED® elastomeric infusion pumps
`(Cardinal Health, Inc.). Stability studies of CUBICIN solutions stored in ReadyMED®
`
`elastomeric infusion pumps identified an impurity (2-mercaptobenzothiazole) leaching from this
`pump system into the CUBICIN solution.
`
`Because only limited data are available on the compatibility of CUBICIN with other IV
`substances, additives and other medications should not be added to CUBICIN single-use vials or
`infusion bags, or infused simultaneously with CUBICIN 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 CUBICIN.

`DOSAGE FORMS AND STRENGTHS
`
`500 mg daptomycin as a sterile, pale yellow to light brown lyophilized powder for reconstitution
`in a single-use vial.
`

`CONTRAINDICATIONS
`
`CUBICIN is contraindicated in patients with known hypersensitivity to daptomycin.
`
`5
`
`WARNINGS AND PRECAUTIONS
`
`
`5.1 Anaphylaxis/Hypersensitivity Reactions
`
`Anaphylaxis/hypersensitivity reactions have been reported with the use of antibacterial agents,
`including CUBICIN, and may be life-threatening. If an allergic reaction to CUBICIN occurs,
`discontinue the drug and institute appropriate therapy [see Adverse Reactions (6.2)].
`
`
`5.2 Myopathy and Rhabdomyolysis
`Myopathy, defined as muscle aching or muscle weakness in conjunction with increases in
`creatine phosphokinase (CPK) values to greater than 10 times the upper limit of normal (ULN),
`has been reported with the use of CUBICIN. Rhabdomyolysis, with or without acute renal
`failure, has been reported [see Adverse Reactions (6.2)].
`
`
`Patients receiving CUBICIN should be monitored for the development of muscle pain or
`weakness, particularly of the distal extremities. In patients who receive CUBICIN, CPK levels
`should be monitored weekly, and more frequently in patients who received recent prior or
`concomitant therapy with an HMG-CoA reductase inhibitor or in whom elevations in CPK occur
`during treatment with CUBICIN.
`In patients with renal impairment, both renal function and CPK should be monitored more
`frequently than once weekly [see Use in Specific Populations (8.6) and Clinical Pharmacology
`(12.3)].
`
`In Phase 1 studies and Phase 2 clinical trials, CPK elevations appeared to be more frequent when
`CUBICIN was dosed more than once daily. Therefore, CUBICIN should not be dosed more
`frequently than once a day.
`CUBICIN should be discontinued in patients with unexplained signs and symptoms of myopathy
`in conjunction with CPK elevations to levels >1,000 U/L (~5× ULN), and in patients without
`reported symptoms who have marked elevations in CPK, with levels >2,000 U/L (≥10× ULN).
`In addition, consideration should be given to suspending agents associated with rhabdomyolysis,
`such as HMG-CoA reductase inhibitors, temporarily in patients receiving CUBICIN [see Drug
`Interactions (7.1)].
`
`
`5.3 Eosinophilic Pneumonia
`Eosinophilic pneumonia has been reported in patients receiving CUBICIN [see Adverse
`Reactions (6.2)]. In reported cases associated with CUBICIN, patients developed fever, dyspnea
`with hypoxic respiratory insufficiency, and diffuse pulmonary infiltrates. In general, patients
`developed eosinophilic pneumonia 2 to 4 weeks after starting CUBICIN and improved when
`
`Reference ID: 3820457
`
`5
`
`
`
`
`
`
`CUBICIN was discontinued and steroid therapy was initiated. Recurrence of eosinophilic
`pneumonia upon re-exposure has been reported. Patients who develop these signs and symptoms
`while receiving CUBICIN should undergo prompt medical evaluation, and CUBICIN should be
`discontinued immediately. Treatment with systemic steroids is recommended.
`
`5.4 Peripheral Neuropathy
`
`Cases of peripheral neuropathy have been reported during the CUBICIN postmarketing
`experience [see Adverse Reactions (6.2)]. Therefore, physicians should be alert to signs and
`symptoms of peripheral neuropathy in patients receiving CUBICIN.
`
`5.5 Potential Nervous System and/or Muscular System Effects in Pediatric
`Patients Younger than 12 Months
`
`Avoid use of CUBICIN in pediatric patients younger than 12 months due to the risk of potential
`effects on muscular, neuromuscular, and/or nervous systems (either peripheral and/or central)
`observed in neonatal dogs with intravenous daptomycin [see Nonclinical Toxicology (13.2)].
`
`
`5.6 Clostridium difficile–Associated Diarrhea
`Clostridium difficile–associated diarrhea (CDAD) has been reported with the use of nearly all
`systemic antibacterial agents, including CUBICIN, and may range in severity from mild diarrhea
`to fatal colitis [see Adverse Reactions (6.2)]. 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, since 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 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
`
`may need to be discontinued. Appropriate fluid and electrolyte management, protein
`supplementation, antibacterial treatment of C. difficile, and surgical evaluation should be
`
`instituted as clinically indicated.
`
`5.7 Persisting or Relapsing S. aureus Bacteremia/Endocarditis
`Patients with persisting or relapsing S. aureus bacteremia/endocarditis or poor clinical response
`should have repeat blood cultures. If a blood culture is positive for S. aureus, minimum
`inhibitory concentration (MIC) susceptibility testing of the isolate should be performed using a
`standardized procedure, and diagnostic evaluation of the patient should be performed to rule out
`sequestered foci of infection. Appropriate surgical intervention (e.g., debridement, removal of
`prosthetic devices, valve replacement surgery) and/or consideration of a change in antibacterial
`regimen may be required.
`Failure of treatment due to persisting or relapsing S. aureus bacteremia/endocarditis may be due
`to reduced daptomycin susceptibility (as evidenced by increasing MIC of the S. aureus isolate)
`
`[see Clinical Trials (14.2)].

`
`
`
`
`
`
`5.8 Decreased Efficacy in Patients with Moderate Baseline Renal Impairment
`Limited data are available from the two Phase 3 complicated skin and skin structure infection
`(cSSSI) trials regarding clinical efficacy of CUBICIN treatment in patients with creatinine
`clearance (CLCR) <50 mL/min; only 31/534 (6%) patients treated with CUBICIN in the intent-to
`treat (ITT) population had a baseline CLCR <50 mL/min. Table 2 shows the number of patients
`by renal function and treatment group who were clinical successes in the Phase 3 cSSSI trials.

`
`
`
`
`
`5.9 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 [see Drug-Laboratory Interactions (7.2)].
`
`
`5.10 Non-Susceptible Microorganisms
`
`The use of antibacterials may promote the overgrowth of non-susceptible microorganisms. If
`superinfection occurs during therapy, appropriate measures should be taken.
`Prescribing CUBICIN 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.
`
`
`6
`ADVERSE REACTIONS
`
`
`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)]
`Peripheral neuropathy [see Warnings and Precautions (5.4)]
`-
`-
`Increased International Normalized Ratio (INR)/prolonged prothrombin time [see
`
`Warnings and Precautions (5.9) and Drug-Laboratory Test Interactions (7.2)]
`
`Because clinical trials are conducted under widely varying conditions, adverse reaction rates
`observed in the clinical trials of a drug cannot be directly compared with rates in the clinical
`trials of another drug and may not reflect the rates observed in practice.
`
`
`6.1 Clinical Trials Experience
`Clinical trials enrolled 1,864 patients treated with CUBICIN and 1,416 treated with comparator.
`
`Complicated Skin and Skin Structure Infection Trials
`
`In Phase 3 complicated skin and skin structure infection (cSSSI) trials, CUBICIN 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 cSSSI
`(4 mg/kg CUBICIN) patients are displayed in Table 4.

`S. aureus Bacteremia/Endocarditis Trial
`In the S. aureus bacteremia/endocarditis trial, CUBICIN was discontinued in 20/120 (16.7%)
`patients due to an adverse reaction, while comparator was discontinued in 21/116 (18.1%)
`patients.
`
`Serious Gram-negative infections (including bloodstream infections) were reported in 10/120
`(8.3%) CUBICIN-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.

`
`Other Trials
`In Phase 3 trials of community-acquired pneumonia (CAP), the death rate and rates of serious
`cardiorespiratory adverse events were higher in CUBICIN-treated patients than in comparator-
`treated patients. These differences were due to lack of therapeutic effectiveness of CUBICIN in
`the treatment of CAP in patients experiencing these adverse events [see Indications and Usage
`(1.3)].

` Laboratory Changes
`
` Complicated Skin and Skin Structure Infection Trials
`
`In Phase 3 cSSSI trials of CUBICIN at a dose of 4 mg/kg, elevations in CPK were reported as
`clinical adverse events in 15/534 (2.8%) CUBICIN-treated patients, compared with 10/558
`(1.8%) comparator-treated patients. Of the 534 patients treated with CUBICIN, 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
`trials.

`
`S. aureus Bacteremia/Endocarditis Trial
`In the S. aureus bacteremia/endocarditis trial, at a dose of 6 mg/kg, 11/120 (9.2%) CUBICIN-
`treated patients, including two patients with baseline CPK levels >500 U/L, had CPK elevations
`to levels >500 U/L, compared with 1/116 (0.9%) comparator-treated patients. Of the 11
`CUBICIN-treated patients, 4 had prior or concomitant treatment with an HMG-CoA reductase
`inhibitor. Three of these 11 CUBICIN-treated patients discontinued therapy due to CPK
`elevation, while the one comparator-treated patient did not discontinue therapy [see Warnings
`and Precautions (5.2)].
