E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study was to evaluate single-dose pharmacokinetic (PK) data on intravenous (i.v.) daptomycin administered at 8 mg/kg as a 1 hour infusion or 10 mg/kg as either a 1 or 2 hour infusion in pediatric subjects aged 2 to 6 years, inclusive, with proven or suspected Gram-positive infection who were receiving standard antibiotic therapy.
|
|
E.2.2 | Secondary objectives of the trial |
The secondary objective was to assess the safety of an 8 or 10 mg/kg single dose of i.v. daptomycin administration as either a 1 or 2 hour infusion in pediatric subjects aged 2 to 6 years, inclusive, with proven or suspected Gram-positive infection who were receiving standard antibiotic therapy. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Male or female subjects between the ages of 2 and 6 years old, inclusive, with suspected or diagnosed Gram-positive infection for which the subject was receiving standard antibiotic therapy were specific candidates for the study. Subjects were required to be clinically stable with no evidence of hemodynamic instability in the 72 hour window prior to enrollment and no history or evidence of renal or hepatic compromise, with calculated creatinine clearance rate (CLcr) 80 mL/min/1.73 m2 as determined by the Schwartz equation, CPK levels <2X upper limit of normal (ULN), and presence of 2 patent i.v. lines (or comparable means of venous access) prior to dosing on Study Day 1. |
|
E.4 | Principal exclusion criteria |
Subjects were to be excluded from the study if they met any of the following criteria:
1. Investigational drug use (including daptomycin) or participation in any experimental procedure in the 30 days preceding study entry;
2. Known allergy/hypersensitivity to daptomycin
3. History of clinically significant cardiovascular, renal, hepatic, pulmonary (well-controlled asthma was acceptable), gastrointestinal, endocrine, hematologic, autoimmune disease or primary immune deficiency;
4. Pneumonia as sole Gram-positive infection being treated with standard antibiotics;
5. Subjects with clinically significant abnormal laboratory test results (including ECGs), as determined by Investigator;
6. Administration of rifampin within 7 days of study drug administration;
7. Body mass index (BMI) that was outside of the 5th to 95th percentile;
8. Subjects in whom collection of the required blood volume would put them at risk of hemodynamic disturbance (at the discretion of Investigator);
9. History of or current clinically significant (at the discretion of the Investigator) muscular disease, nervous system or seizure disorder;
10. Administration of intramuscular (IM) injection between baseline and study drug administration or expected IM injection within 24 hours following dosing;
11. Expected surgical procedure(s) within 24 hours prior to and following dosing;
12. Unexplained muscular weakness, history of peripheral neuropathy, Guillain-Barré or spinal cord injury;
13. History of or current rhabdomyolysis.

E.5 End points |
E.5.1 | Primary end point(s) |
Blood samples for determination of the plasma PK profile of daptomycin |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Blood samples for determination of the plasma PK profile of daptomycin were to be obtained at 8 time points: 0 minutes (prior to infusion), 30 minutes (during infusion), 60 minutes (within 2 minutes following the end of 1 hour infusion or during the 2 hour infusion), 120 minutes (within 2 minutes following the end of the 2 hour infusion), 4, 7, 12, and 24 hours relative to the start of the infusion. |
|
E.5.2 | Secondary end point(s) |
A treatment-emergent adverse event (TEAE) was an AE that occurred during a defined period of the study that was new in onset, or was a preexisting condition that was aggravated in severity or frequency. |
