NCT07732699

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.

Outcome Measures

Primary Outcomes (1)

  • Average Daily Symptom Burden

    Symptom burden measured daily using the Pediatric Rhinosinusitis Symptom Scale (PRSS Version 2.0). PRSS scores range from 0 to 40, with higher scores indicating worse symptoms. Daily scores are averaged over Days 1-10

    Days 1-10

Secondary Outcomes (2)

  • Safety Outcome: Diarrhea

    Randomization through Day 10

  • Recurrence of Acute Sinusitis or Acute Otitis Media

    Days 11-90

Study Arms (4)

Amoxicillin

ACTIVE COMPARATOR

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.

Drug: Amoxicillin

Amoxicillin-Clavulanate

ACTIVE COMPARATOR

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.

Drug: Amoxi Clavulanate

Amoxicillin Placebo

PLACEBO COMPARATOR

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.

Drug: Amoxicillin Placebo

Amoxicillin-Clavulanate Placebo

PLACEBO COMPARATOR

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.

Drug: Amoxicillin-Clavulanate Placebo

Interventions

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

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

Amoxicillin Placebo

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

Amoxicillin-Clavulanate Placebo
