Clinical Trial Summary

The hypothesis for this trial is that an antibiotic strategy for the management of non-severe community-acquired alveolar pneumonia in children aged 3 to 59 months, including amoxicillin 80-100 mg/kg/day for at least 3 days in case of rapid response and 5 days in case of delayed response, would not be inferior to current French recommendations (antibiotic therapy for 5 days in case of rapid response and 7 days in case of delayed response) in terms of treatment of failure rate at 7 days.

Description:

Introduction:

The World Health Organization (WHO) has declared antimicrobial resistance to be one of the 10 greatest threats to public health. As such, it has issued recommendations for children for the diagnosis and treatment of pneumonia with amoxicillin for 3 days. However, this strategy includes viral infections and therefore cannot be extrapolated directly to countries with a high level of access to healthcare, where the aim is to treat only bacterial pneumonia and for the shortest possible time to limit the emergence of resistant bacteria. Thus, our study proposes to use a definition of pneumonia adapted to countries with a high level of access to healthcare and to test an adaptive treatment regimen including a clinical reassessment at D3, which will propose a treatment limited to 3 days in case of rapid response and 5 days in case of delayed response.

Aim:

The aim of this trial is to demonstrate the non-inferiority of a strategy of antibiotic treatment with amoxicillin 80-100 mg/kg/day for 3 days in the case of a rapid response or 5 days in the case of a delayed response, versus antibiotic treatment for 5 days in the case of a rapid response or 7 days in the case of a delayed response for the management of non-severe community-acquired alveolar pneumonia in children between 3 and 59 months, in terms of the rate of treatment failure at 7 days.

Methods:

As the hypothesis is not that a shorter antibiotic regimen is more effective in this indication, a non-inferiority trial is the most appropriate design to assess whether this efficacy is broadly comparable with the reference regimen. The primary endpoint chosen is the one already used in an international clinical trial on this disease in children, which has been agreed upon.

In order to meet the objective of the study, 1100 patients will be included.

• At D0, patients will be included and randomized by the investigator, and will begin their treatment: Short arm: treatment by amoxicillin 80-100 mg/kg/d for 3 days if rapid response or 5 days if delayed response; or Long arm: treatment by amoxicillin 80-100 mg/kg/d for 5 days if rapid response or 7 days if delayed response. A prescription and follow-up diary will be given to the family.

• At D3, the doctor will assess the response to the treatment. If the response is assessed as rapid, then the investigator will reduce the duration of antibiotic treatment depending on the arm to which the child has been randomized. Parents will continue to complete the follow-up diary until D7.

• At the D7 visit, the investigator evaluates the primary endpoint and some of the secondary endpoints.

• At the D30 visit, the investigator assesses of last secondary endpoints.

Given the non-inferiority design, data will be analyzed on a per protocol basis for the primary analysis. The per-protocol population will be defined by radiologist of pneumonia diagnosis, at least one dose of amoxicillin, and having primary endpoint assessment data at 7 days. Non-inferiority will be declared if the lower bound of the confidence interval of the difference in failure rate between the 3-day and 5-day arms is less than 3.5%.

Intervention

Drug:
• Quick response: Amoxicillin for 3 days
Once the diagnosis of community-acquired alveolar pneumonia has been made, the investigator taking charge of the child writes a prescription for amoxicillin at a dosage of 80-100 mg/kg/day in 3 oral doses (morning, noon and evening), for a period of 4 days, before delivery of treatment to the family. The investigator will carry out a clinical re-evaluation on day 3 (D3), during which he will decide on the final duration of treatment. In case of rapid response*: Immediate stop of antibiotherapy (after 9 complete doses) *A rapid response is determined by a favorable clinical evolution (MASCOT 2002 study)
• Delayed response: Amoxicillin for 5 days
Once the diagnosis of community-acquired alveolar pneumonia has been made, the investigator taking charge of the child writes a prescription for amoxicillin at a dosage of 80-100 mg/kg/day in 3 oral doses (morning, noon and evening), for a period of 4 days, before delivery of treatment to the family. The investigator will carry out a clinical re-evaluation on day 3 (D3), during which he will decide on the final duration of treatment. In case of delayed response: Continuation of antibiotic therapy for up to 5 days
• Quick response: Amoxicillin for 5 days
