Active Comparator: Clindamycin IV-ages 2 to 11 Years Old (BMI 85-95th Percentile)
Clindamycin IV: Children ages 2 to 11 years old with BMI 85th to 95th percentile. Their schedule of IV Clindamycin administration included 30-40 mg/kg/day dosed every 6 or every 8 hours with a maximum daily dose of 2.7 grams/day. Dosing greater than 2.7g/day was allowed for children receiving clindamycin as part of clinical care.

- Pharmacokinetics (PK) - Clearance (Cl) in Participants Who Received Multiple Doses of Intravenous (IV) Clindamycin. [ Time Frame: After first study dose of IV Clindamycin through Day 14 (minimum of 3 samples; maximum of 6). ]
In order to understand the impact of obesity on clindamycin PK, PK data were combined to build a PK model from 3 studies that included both obese and non-obese children: 1) PTN_Clinda Obese study (clinicaltrials.gov/ct.gov identifier NCT01744730) n = 21; 2) PTN_POPS study (ct.gov identifier NCT01431326) n = 178; and 3) Staph Trio study (ct.gov identifier NCT01728363) n = 21. The data from the Staph-Trio study were only included for PK modeling and not intended to be compared in the analysis.
PK sampling schedule for PTN_Clinda Obese was: Pre-dose 0 (within 15 minutes prior to IV clindamycin dose), 0.5 (± 5 minutes) after dose was administered, 1-1.5 hours (hrs) after dose, 3-4 hrs after, 5-6 hrs after, and pre-next dose. Samples were collected on multiple days and averaged to arrive at a single value. Comparison of empirical Bayesian Estimates (EBE) for clearance by age cohort are presented below.
Sampling schedule details for PTN_POPS and Staph Trio were comparable.
