Pharmacokinetics (PK) and Safety Evaluation of Daptomycin in Children Ages 3-24 Months With Proven or Suspected Gram-positive Infections or Peri-Operative Subjects Receiving Prophylactic Antibiotics

Study Overview
=================
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 .

Official Title
-----------------
An Evaluation of the Pharmacokinetic Profile and Safety of a Single Dose of Daptomycin in Pediatric Subjects Aged 3 Months to Twenty-Four Months Who Are Concurrently Receiving Standard Antibiotic Therapy for Proven or Suspected Bacterial Infection Including Peri-Operative Prophylactic Use of Antibiotics

Conditions
-----------------
Gram Positive Bacterial Infection

Intervention / Treatment
-----------------
* Drug: Daptomycin


Participation Criteria

Eligibility Criteria
-----------------
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: Investigational drug use (including daptomycin) or participation in any experimental procedure in the 30 days preceding study entry; 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.
