Efficacy and Tolerability of Artesunate Amodiaquine Versus Chloroquine in the Treatment of Uncomplicated Plasmodium Vivax Malaria

Information source: Sanofi
ClinicalTrials.gov processed this data on August 20, 2015
Link to the current ClinicalTrials.gov record.

Condition(s) targeted: Malaria

Intervention: ARTESUNATE + AMODIAQUINE (Drug); Chloroquine (Drug)

Phase: Phase 3

Status: Completed

Sponsored by: Sanofi

Official(s) and/or principal investigator(s):
Clinical Sciences & Operations, Study Director, Affiliation: Sanofi


Primary Objective:

- To demonstrate the non-inferiority of corrected adequate clinical and parasitological

response at Day 28 of Artesunate Amodiaquine (ASAQ) versus chloroquine Secondary Objectives:

- To assess the non inferiority on the same way as the main criteria:

- at Day 28 before corrected cure rate

- at Day 14 and Day 42 before and after corrected cure rate

- To compare the two groups of treatment in terms of:

- Efficacy:

- Proportion of aparasitaemic patients at 24, 48 an 72 hours

- Proportion of afebrile patients at 24, 48 and 72 hours

- Percentage of gametocyte carriers during follow-up

- Evolution of the mean of gametocytes during the 42 days of follow-up

- Evolution of haemoglobin value between Day 0 and Day 7, Day 0 and Day 28

- Clinical and biological tolerability:

- Proportion of any adverse event

- Biological safety: haematology (Red blood cells, Haemoglobin, White Blood Cells,

neutrophils, platelets), biochemistry (creatinine, transaminases (alanine amino transferase/ALT), bilirubins)

- ECG (electro encephalogram) (Day 0, Day 3,Day 28) only for patients 10 years old

and above

Clinical Details

Official title: A Randomised Comparative Study to Assess the Efficacy and Tolerability of Blood Schizonticidal Treatments With Artesunate Amodiaquine Winthrop® / Coarsucam (ASAQ) Versus Chloroquine (CQ) for Uncomplicated Plasmodium Vivax Monoinfection Malaria

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Assessment of clinical and parasitological efficacy based on temperature and parasitemia after Polymerase chain reaction (PCR) correction

Secondary outcome:

Assessment of clinical and parasitological efficacy based on temperature and parasitemia before and after PCR correction at D14 and D42 and before PCR correction at D28

Number of patients without parasite

Number of patients without fever

Number of patients with gametocytes

Change from baseline in Haemoglobin levels

Incidence and severity of adverse events collected

ECG (QTc) changes in patients group aged >= 10 years from baseline

Assessment of biological tolerability (bilirubin, ALAT, Creatinine, Leukocytes, Neutrophils and platelets count) from baseline

Detailed description: Each patient will be followed for a period of 42 days


Minimum age: 6 Months. Maximum age: N/A. Gender(s): Both.

- Written informed consent of the patients and for children written informed consent of

the parents/legal representative for children. Children able to understand the objectives and the risks of the study will sign an assent form. Exclusion criteria:

- Known project of leaving the investigator site area during the follow-up period (42

- Pregnant or breast-feeding women

- Women with childbearing potential not willing to use an effective contraceptive

method(s) for the duration of the study

- Known severe concomitant or underlying disease
