Study Details

Brief summary:

This study is being conducted at multiple hospitals and clinics to better understand whether antibiotics truly help children feel better when they have a sinus infection (acute sinusitis). Children in the study are randomly assigned (like flipping a coin) to receive either amoxicillin, amoxicillin-clavulanate, or a placebo (a look-alike medicine with no active antibiotic). Neither families nor study staff know which treatment the child is receiving during the study. The main goal is to compare how severe children's symptoms are each day while on these treatments. Parents or caregivers will report symptoms daily using a simple electronic diary. The study will also examine whether factors such as the severity of the child's illness or signs of allergies affect how well antibiotics work. The results will help guide better treatment decisions for children with sinus infections.

Interventions and Outcome Measures

Arms

active comparator: Amoxicillin

Participants randomized to this arm will receive oral amoxicillin for the treatment of acute sinusitis (AS). Caregivers will complete daily electronic symptom diaries throughout the treatment period.

active comparator: Amoxicillin-Clavulanate

Participants randomized to this arm will receive oral amoxicillin-clavulanate for the treatment of AS. Caregivers will complete daily electronic symptom diaries throughout the treatment period.

placebo comparator: Amoxicillin Placebo

Participants randomized to this arm will receive a matching oral placebo for the treatment of AS. Caregivers will complete daily electronic symptom diaries throughout the treatment period.

placebo comparator: Amoxicillin-Clavulanate Placebo

Participants randomized to this arm will receive a matching oral placebo for the treatment of AS. Caregivers will complete daily electronic symptom diaries throughout the treatment period.

Interventions

Amoxicillin

Amoxicillin administered orally at protocol-specified, weight-based dosing consistent with standard pediatric treatment guidelines for AS, for the defined treatment duration.

Amoxi Clavulanate

Amoxicillin-clavulanate administered orally at protocol-specified, weight-based dosing consistent with standard pediatric treatment guidelines for AOM or AS, for the defined treatment duration.

Amoxicillin Placebo

Matching placebo administered orally according to the same dosing schedule and treatment duration as the active comparator arms

Amoxicillin-Clavulanate Placebo

Matching placebo administered orally according to the same dosing schedule and treatment duration as the active comparator arms.

Primary outcome measure
