| Study objectives | Primary objective: To evaluate whether injectable ampicillin plus gentamicin reduces treatment failure in children, aged 2 - 59 months, with very severe pneumonia by 30% or more compared to chloramphenicol after completing 5 days of therapy. The specific null hypothesis to be tested is that treatment failure will be equal in children aged 2 - 59 months with very severe pneumonia whether treated with injectable chloramphenicol or injectable ampicillin plus gentamicin. Secondary objectives: 1. To determine the proportion of treatment failures by 48 hours after randomisation 2. To determine the proportion of children with treatment failure at 11 days after randomisation 3. To determine the proportion of children with treatment failure at 21 - 30 days after randomisation 4. To report the proportion of children who died up to Day 30 after randomisation 5. To determine bacterial pathogens in the etiology of very severe pneumonia 6. To determine the antimicrobial susceptibility of bacterial pathogens causing very severe pneumonia 7. To determine predictors of treatment failure in children with very severe pneumonia Please note that the following changes have been made to this record: the site at Zambia only enrolled patients form April 2001 to November 2001 and then the enrolment was stopped there. The DSMB ended accrual at the Zambia site after 23 enrolments (2.4% of total) in November 2001 because of a high mortality rate - likely due to Human Immunodeficiency Virus (HIV)/Acquired Immune Deficiency Syndrome (AIDS). A new site at in Ecuador was added in March 2003 that started enrolling patients in April 2003. |

| Health condition(s) or problem(s) studied | Severe pneumonia |
| Intervention | For the primary end-point, a total of two looks at the data would require 1,182 patients (591 in each group) to be studied. This sample size assumes a study power of 80% to look for differences between the groups, and maintains an overall two-sided alpha level of 0.05 and includes adjustment for 2% loss to follow-up. Patients will be radomised to: Group 1: 5 days of injectable chloramphenicol in hospital followed by 5 days of oral chloramphenicol at home Group 2: 5 days of injectable ampicillin and gentamicin in hospital followed by 5 days of oral ampicillin and gentamicin at home |

| Pharmaceutical study type(s) | |
| Phase | Not Specified |
| Drug / device / biological / vaccine name(s) | Chloramphenicol, ampicillin, gentamicin |
| Primary outcome measure | The primary outcome variable is "treatment failure at day 6" defined as follows: 1. If at any time after randomisation the following occur: 1.1. Death 1.2. Development of bacterial meningitis, empyema, septic shock or renal failure 1.3. Serious adverse events leading to change of therapy or any modification of antibiotic therapy before day 6 (modification of the dosage of the antibiotic will not be considered as a "treatment failure") 1.4. Left Against Medical Advice (LAMA), or withdrawal of consent (reason of including this in treatment failure is because parents may LAMA or withdraw the consent thinking their child is not improving on the study treatment), or loss to follow-up OR 2. Development of any of the two signs at 48 hours after randomisation: 2.1. Worsening of tachypnoea (defined as 20 breaths above baseline), or 2.2. Development/persistence of abnormal sleepiness or difficulty in awakening, or 2.3. Development/persistence of inability to drink OR 3. Development of two or more of the following at Day 6 after randomisation: 3.1. Worsening of tachypnoea (defined as 20 breaths above baseline, or 3.2. Development/persistence of abnormal sleepiness or difficulty in awakening, or 3.3. Development/persistence of inability to drink |
| Secondary outcome measures | 1. Treatment failures, as defined above, 48 hours after randomisation 2. Treatment failures, as defined above, 11 days after randomisation 3. Treatment failures, as defined above, 21 - 30 days after randomisation (if a patient develops signs given for treatment failure within two weeks after stopping treatment it will be considered a relapse) 4. Deaths by 21 30 days after randomisation 5. Bacterial pathogens isolated in blood cultures from children with very severe pneumonia 6. Antimicrobial susceptibility in blood culture isolates from children with very severe pneumonia |
