NCT ID: NCT02630992

Last Updated: 2018-01-03

Results Overview

Participants receiving formulation 1 were administered amoxicillin-clavulanate potassium containing a reduced concentration of clavulanate potassium, 600 mg/21.5 mg/5 mL (a ratio of 28:1), administered at 90/3.2 mg/kg/day in two divided doses for 10 days. Protocol-defined diarrhea is defined as the occurrence of three or more watery stools in 1 day or two watery stools daily for 2 consecutive days and is limited to events associated with study product.

Timeframe: From 72 hours after the initial AOM until the end-of-treatment visit. The mean day for this visit was 14.9.

Population: The number of participants is equal to the number of children receiving formulation 1 who had an end-of-treatment assessment at or before the day 12 visit.

Participants receiving formulation 1 were administered amoxicillin-clavulanate potassium containing a reduced concentration of clavulanate potassium, 600 mg/21.5 mg/5 mL (a ratio of 28:1), administered at 90/3.2 mg/kg/day in two divided doses for 10 days. Treatment failure is defined as substantial persistence or worsening of symptoms specifically attributable to AOM or of otoscopic signs of acute inflammation (bulging of the TM or intense erythema) after 72 hours from the initial AOM, such that additional antimicrobial therapy is deemed advisable. Clinical success is defined as complete or substantial resolution of symptoms specifically attributable to AOM for 48 hours and of otoscopic signs of acute inflammation (bulging of the TM or intense erythema), with or without persistence of middle-ear effusion, such that no additional antibiotic therapy is deemed advisable.

Timeframe: Day 1 of administration of amoxicillin-clavulanate until the day 7 visit. The mean day for this visit was 7.5.

Population: The number of participants is equal to the number of children receiving formulation 1 who had a day 7 assessment.

Participants receiving formulation 1 were administered amoxicillin-clavulanate potassium containing a reduced concentration of clavulanate potassium, 600 mg/21.5 mg/5 mL (a ratio of 28:1), administered at 90/3.2 mg/kg/day in two divided doses for 10 days. An assessment of participants was conducted at the day 7 visit using the AOM-SOS scale. The AOM-SOS scale measures five discrete items: tugging of ears, crying, irritability, difficulty sleeping, and fever. Parents are asked to rate these symptoms in comparison with the child's usual state, as "none," "a little," or "a lot," with corresponding scores of 0, 1, and 2. Thus, total scores range from 0 to 10, with higher scores indicating greater severity of symptoms.

Population: The participants are the children receiving formulation 2 whose parent or guardian agreed to a single blood draw after administration of a single dose of amoxicillin-clavulanate and who had an ensuing measure of plasma concentration.

Participants receiving formulation 2 were administered amoxicillin-clavulanate potassium containing a reduced concentration of clavulanate potassium, 600 mg/21.5 mg/5 mL (a ratio of 28:1), administered at 80/2.85 mg/kg/day in two divided doses for 10 days. Plasma concentration of clavulanate 1.425 mg/kg/dose was measured. Data points up to 4 hours with a standard deviation of 0 indicate that the assessment was available for only one child.
