Brief Summary:
This study is aimed to compare the efficacy and safety of medications currently used in Brazil for treatment of visceral leishmaniasis. The investigators will compare the effects of meglumine antimoniate, two formulations of amphotericin B: deoxycholate and liposomal, and a combination of meglumine plus the liposomal amphotericin B formulation. The study is designed to demonstrate the difference in efficacy measured as cure rate at six months after treatment and the safety profile based on the adverse event rate observed with each intervention.

Condition or disease Intervention/treatment Phase
Visceral Leishmaniasis Drug: Antimoniate of N-methylglucamine Drug: amphotericin B deoxycholate Drug: Liposomal amphotericin B Phase 4

Detailed Description:

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.

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

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.

1mg/kg/d, I.V. for 14 consecutive days.
Other Names:
  • Fungizone
  • Anforicin B

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: AmBisome

Drug: Antimoniate of N-methylglucamine

Other Name: Glucantime

Primary Outcome Measures :
  1. 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.

Secondary Outcome Measures :
  1. Improvement rate [ Time Frame: 30 days ]
    Fever disappearing, stable or improving hematological lab abnormalities plus any spleen size reduction.

  2. 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.

  3. 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.

  4. 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.
