Gram Positive Infection, Concurrent Antibiotic Treatment
Brief summary
This is a research study designed to look at the pharmacokinetics (distribution, breakdown, and removal) and tolerability of a single dose of daptomycin in patients aged 3 months to 24 months who have proven or suspected infections that are caused by a specific group of bacteria (called Gram-positive bacteria)or perioperative subjects that are receiving prophylactic antibiotics .
Interventions
DRUGDaptomycin
Group 1: Ages 13 months to 24 months inclusive. Six subjects dosed at 6 mg/kg as a 30 minute infusion; Group 2:Ages 7 months to 12 months inclusive: Six subjects will receive a dose of 4 mg/kg as a 30 minute infusion; Group 3: Ages 3 months to 6 months inclusive: Six subjects will receive a dose of 4 mg/kg as a 30 minute infusion.

Inclusion criteria
1\. Written parental (or appropriate legal representative) informed consent prior to any study-related procedure not part of normal medical care; 2.1 Male or female between the ages of 3 months and 24 months, inclusive; 3. Able to comply with the protocol for the duration of the study; 4.1 Clinically stable with no evidence of hemodynamic instability (defined as a requirement for inotropic or vasodilatory support to manage blood pressure) in the 24 hour window prior to first dose, and no history or evidence of renal or hepatic compromise; 5.1 Suspected or diagnosed bacterial infection for which the subject is receiving standard antibiotic therapy; including prophylactic use of antibiotics peri-operatively; 6. A calculated creatinine clearance rate (CLcr) ≥ 80 ml/min/1.73m2 as determined by the Schwartz equation at baseline; 7. Creatine phosphokinase (CPK) levels less than 2X ULN (upper limit of normal) at baseline; 8.1 Presence of two patent intravenous lines (or comparable means of venous or arterial access)prior to dosing on Study Day 1. A single intravenous line (or comparable means of venous access) is acceptable for both drug administration and sample collection if reasonable effort to gain a second line is unsuccessful. The line must be flushed as described in Appendix B of the protocol prior to obtaining PK samples. PK sample can be obtained from a peri-operatively placed arterial line. Arterial PK samples should be indicated on the CRF.
Exclusion 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; 3.1 History of clinically significant, renal, hepatic, autoimmune disease or primary immune deficiency; 4\. Deleted 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. Deleted 8. Subjects in whom collection of the required blood volume would put them at risk of hemodynamic disturbance (at the discretion of Investigator); 9. Deleted; 10.1 Planned administration of intramuscular injection within 12 hours following study administration unless approved by the Medical Monitor; 11. Deleted 12.1 Guillian-Barre or spinal cord injury; 13. History of or current rhabdomyolysis.
