Condition
T.b. rhodesiense second stage trypanosomiasis
Intervention
New drug treatment schedule for melarsoprol with or without standard pre-treatment with suramin.
Intervention type
Drug
Pharmaceutical study type(s)
Phase
Phase II
Drug/device/biological/vaccine name(s)
Melarsoprol and suramin
Primary outcome measure
1. Efficacy: parasitological and clinical cure 24 hours after treatment
2. Safety: determined by a combined endpoint of serious adverse drug reactions with fatal outcome and other causes of death (e.g. disease-related opportunistic infections). The assessment of safety through the end of treatment evaluation, measurement of vital signs, physical examinations and the use of concomitant medications is included. Adverse events which are spontaneously reported between the end of treatment evaluation and 30 days post-treatment will also be collected.
Secondary outcome measures
Parasitological and clinical cure 3, 6 and 12 months after completion of treatment and relapse, re-infection and death
