Scientific title
Study objectivesWe hypothesise that gatifloxacin is more effective than ofloxacin in the treatment of enteric fever.
Ethics approval(s)Ethics approval received from:
1. Oxford Tropical Medicine Research Ethics Committee (OXTREC) (UK) on the 20th June 2006 (ref: 23/08)
2. Nepalese Local Ethics Committee on the 24th June 2008
Health condition(s) or problem(s) studiedEnteric fever (typhoid and paratyphoid fever)
InterventionGatifloxacin (10 mg/kg/day) once daily oral dose for 7 days versus ofloxacin (20 mg/kg/) twice daily oral dose for 7 days.

1. Prior to admission to the study:
1.1. Full history and clinical examination. In particular the following data will be documented: clinical manifestations according to a standard case record form (CRF).
1.2. Chest X-ray and other radiological investigations, including abdominal ultrasound, as clinically indicated

2. On admission to the study:
2.1. Name and address of the patient will be recorded on a detachable cover sheet of the CRF, (for mapping purposes)
2.2. Full blood counts including white cell differential, biochemistry (serum glutamic oxaloacetic transaminase [SGOT], serum glutamic pyruvic transaminase [SGPT], creatinine, glucose)
2.3. Blood for on-going host genetic studies of enteric fever from the patient
2.4. Microbiology:
2.4.1. Blood cultures (5 - 8 ml of blood)
2.4.2. Stool culture pre-treatment
2.5. Blood for typhoid diagnostic study (2 ml ethylenediaminetetraacetic acid [EDTA] blood)

3. Day 1 - Discharge:
Patients will be managed as outpatients and seen at home every day to day 10 or longer (until the patient gets better). The Nurse/Dr/Paramedic will visit the patient twice per day (at 12 hourly intervals) for 10 days or longer (until the patient gets better).
3.1. Treatment will be given under directly observed therapy
3.2. GPS mapping of patient's house
3.3. Axillary temperature will be recorded at 12 hourly intervals
3.4. Random glucose monitoring, daily from day 1 till day 8
3.5. Blood for pharmacokinetic study (2 ml of blood, sparse sampling, either one blood sample or two blood samples after the third dose of gatifloxacin or ofloxacin)

At all visits fever and clinical symptoms will be monitored (feeling better or not, fever, headache, anorexia, pain abdomen, cough, constipation, diarrhoea, vomiting, nausea, confusion, black stool, sweating/dizziness, fainting/blackouts, nocturia/polyuria or others) and recorded with particular attention to:
3.6. Any side effects of the drug
3.7. Complications of the disease (if any occur)

4. Day 8:
4.1. Patients will be re-examined by the study physicians at Patan Hospital
4.2. Blood cultures will be performed day 8
4.3. Full blood counts including white cell differential, biochemistry (SGOT, SGPT, creatinine) will be repeated
4.4. Faeces will be re-cultured day 8
4.5. Blood for typhoid diagnostic study (2 ml)

5. Day 15:
All patients will be re-examined by the study physicians at Patan Hospital.

Further follow up will be performed for six months.
Intervention typeDrug
Pharmaceutical study type(s)
PhaseNot Specified
Drug / device / biological / vaccine name(s)Gatifloxacin, ofloxacin
Primary outcome measureThe overall failure of the treatment. Overall failure of treatment is defined as the occurrence of any one of the following (acute treatment failure plus complication plus relapse):
1. Persistent fever at day 10 of treatment
2. Blood culture positive at day 10 of treatment
3. Need for 'rescue' treatment with ceftriaxone
4. Culture confirmed relapse within 28 days of starting therapy
5. The development of any typhoid fever related complications during treatment:
5.1. Clinically significant bleeding
5.2. Fall in the Glasgow Coma Score
5.3. Perforation of the gastrointestinal tract
5.4. Admission to hospital within 28 days of starting therapy
Secondary outcome measures1. Fever clearance time (FCT)
2. Syndromic clinical relapse occurring within 28 days of starting therapy that is thought to be due to typhoid or paratyphoid fever (fever, abdominal pain, change in bowel habit, headache, etc), blood cultures negative and no other cause identified
3. Stool carriage of Salmonella typhi or S. paratyphi at 1, 3, or 6 months
Overall study start date01/08/2008
Completion date31/07/2010
