Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to evaluate the efficacy of colistin compared with colistin plus fosfomycin against carbapenem-resistant Acinetobacter baumanii infection in Thailand. The main questions it aims to answer the following main questions:

1. Which group has better clinical response at end of treatment
2. Which group has better clinical response at 72 hours and micrological cure at 72 hours and at end of treatment

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participants will be randomized in a 1:1 ratio to receive a combination of intravenous colistin plus intravenous fosfomycin (combination group) or colistin alone (monotherapy group) to determine if monotherapy or combination therapy has a better outcome.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Colistin group

Participants receive intravenous colistin (colistinmethate soidum) 5 mg/kg/day (dosage will be adjusted according to creatinine clearance) and colistin nebulization at 80 mg every 8 hours in case of pneumonia.

Group Type ACTIVE_COMPARATOR

Colistin Sodium Methanesulfonate

Intervention Type DRUG

Intravenous colistin (colistinmethate soidum) 5 mg/kg/day intravenous (dosage will be adjusted according to creatinine clearance). The duration of treatment ranges from 10 to 14 days, depending on the site of infection and clinical responsiveness.

Colistin plus fosfomycin group

Participants receive intravenous colistin (colistinmethate soidum) (dosage regimen same as colistin group plus intravenous fosfomycin (dosage will be adjusted according to creatinine clearance and MIC).

Group Type ACTIVE_COMPARATOR

Colistin Sodium Methanesulfonate plus Fosfomycin

Intervention Type DRUG

Intravenous colistin(dosage is same as colistin group) plus intravenous fosfomycin(dosage will be adjusted according to MIC and creatinine clearance). The duration of treatment ranges from 10 to 14 days, depending on the site of infection and clinical responsiveness.
