|Visceral Leishmaniasis||Drug: Antimoniate of N-methylglucamine Drug: amphotericin B deoxycholate Drug: Liposomal amphotericin B||Phase 4|
Visceral leishmaniasis is a relevant public health problem in Brazil with approximately 3500 cases registered every year. Eight percent lethality rate has been observed during the past decade in spite of free of charge availability of antileishmanial drugs supplied by the public health system.
The present study was designed as a phase IV, multicentric, open label, active controlled clinical trial targeted to visceral leishmaniasis adult and pediatric cases.
The current drugs approved for visceral leishmaniasis treatment in Brazil will be compared in four treatment groups: meglumine antimoniate, amphotericin B deoxycholate, liposomal amphotericin B and a combination of single dose of liposomal amphotericin B plus meglumine antimoniate. Meglumine antimoniate treated patients will constitute the active control group.
Drugs will be compared based on the cure rate observed after six months follow-up.
The study arm submitted to treatment with Amphotericin B deoxycholate was suspended in September 2012.

|Masking:||None (Open Label)|
|Official Title:||Multicentric Efficacy and Safety Study of Antileishmanial Drugs for Treatment of Visceral Leishmaniasis in Brazil|
|Study Start Date :||February 2011|
|Actual Primary Completion Date :||October 2014|
|Actual Study Completion Date :||February 2015|
Active Comparator: Meglumine antimoniate
Antimoniate of N-methylglucamine 20mg/kg/d, I.V. for 20 consecutive days.
Drug: Antimoniate of N-methylglucamine
Antimoniate of N-methyl glucamine 20mg/kg/d of pentavalent antimonial, I.V. for 20 consecutive days.
Other Name: Glucantime
Experimental: Liposomal Amphotericin B
Liposomal amphotericin B 3mg/kg/d I.V. for 7 consecutive days.
Drug: Liposomal amphotericin B
3mg/kg/d, I.V. for 7 consecutive days.
Other Name: AmBisome
Experimental: Amphotericin B
Amphotericin B deoxycholate 1mg/kg/d I.V. for 14 consecutive days. This arm was suspended in September 19th, 2012, because of a relevant excess of adverse events and serious adverse events associated with this experimental intervention in comparison with the active comparator and the other two experimental arms. The suspension of this study arm was supported by a DSMB statement.
Drug: amphotericin B deoxycholate
1mg/kg/d, I.V. for 14 consecutive days.
Experimental: Combination therapy
Liposomal amphotericin B 10mg/kg/d, I.V. single dose on day 0 plus Antimoniate of N-methylglucamine 20mg/kg/d for 10 consecutive days on days 1 to 10.
Drug: Liposomal amphotericin B
10mg/kg/d, I.V. single dose.
Other Name: AmBisomeDrug: Antimoniate of N-methylglucamine
20mg/kg/d of pentavalent antimonial I.V. for 10 days
Other Name: Glucantime
- Cure rate [ Time Frame: 6 month ]Complete remission of clinical signs and symptoms, three months after treatment plus normal hematological lab evaluation and no relapse at sixth month follow-up.
- Improvement rate [ Time Frame: 30 days ]Fever disappearing, stable or improving hematological lab abnormalities plus any spleen size reduction.
- Relapse rate [ Time Frame: (6 months post treatment) After treatment until the sixth month of follow-up ]Reappearing of signs and symptoms after any improvement observed after treatment, during the six months follow-up period.
- Serious adverse events rate [ Time Frame: During (day one) and within the six months follow-up ]Rate of adverse events defined as conditions which fulfilled any of the following: results in death, is life threatening, requires inpatient hospitalization or prolongs hospitalization, results in persistent or significant disability/incapacity, causes a congenital anomaly or birth defect or it is considered as a important medical event for the responsible clinician.
- Adverse event rate and intensity [ Time Frame: During (day one) treatment and within the six months follow-up ]Cumulative rate of any adverse event, including clinical, laboratory and electrocardiographic abnormalities observed within the treatment and follow-up periods. All adverse events will be graded using an adapted ACTG 0-4 scale.
