Introduction of Eurartesim® in Burkina Faso, Mozambique, Ghana and Tanzania
Observational Study to Evaluate the Clinical Safety After Introduction of the Fixed Dose Artemisinin-based Combination Therapy Eurartesim® (Dihydroartemisinin/Piperaquine [Dha/Pqp]) in Public Health Districts in Sub-Saharan Africa.
Study Overview
Detailed Description
Study will be performed in public health facilities in up to 7 selected HDSS centres (Health and Demographic Surveillance sites) within the HDSS in Burkina Faso (1), Mozambique (1), Ghana (3), and Tanzania (2), where Eurartesim® will be used as first-line treatment of uncomplicated malaria episodes.
Primary:
Evaluate the safety of Eurartesim® when used under usual conditions in 10,000 patients with signs and symptoms of uncomplicated malaria confirmed by a parasitological diagnosis (Microscopy/Rapid Diagnostic Test) or, when this test is not available, by WHO diagnostic criteria.
Main Secondary:
Intensive assessment of a nested subset of 1,000 patients to evaluate the effect of the administration of Eurartesim® on blood biochemistry, full blood count, WBC differential count and QTc intervals. QTc interval and piperaquine concentration relationship will also be investigated in selected centers.
Other Secondaries:
Although it is expected that the vast majority of patients will be infected with P. falciparum, comparisons of the clinical tolerability of Plasmodium falciparum infected patients versus patients infected with other Plasmodia, as confirmed by the thick blood smear results, will be carried-out in the nested subset of 1,000 patients.
Assessment of the relationship between the occurrence of Adverse Events and the administration of concomitant medications will also be evaluated in the subset of 1,000 patients.
All patients visiting Health facilities in the HDSS areas and for whom a diagnosis of uncomplicated malaria (according to the WHO criteria) is suspected or confirmed by a parasitological diagnosis (Microscopy/Rapid Diagnostic Test) and who have signed informed consent/assent (a parent/guardian for children below 18 years old) will be included in the study. In the subset of 1,000 patients, the presence of Plasmodia of any species will be confirmed microscopically.
A thick blood smear will be prepared for further microscopic diagnosis in all the patients. Eurartesim® tablets will be prescribed to the patients (or to the parents/guardians, if the patients are children) meeting the protocol inclusion criteria before the results of the thick blood smear are known.
The patients will be contacted at Day 5 (± 2 days), in order to capture recovery status and all the experienced adverse events. A visit by the community health agent will be scheduled on all the cases in which the information collected during the telephone contact should be considered incomplete or unreliable ones. Special procedures will be followed in case of serious and/or severe adverse events and events classified of special interest (see specific section).
The subset of 1,000 patients will be intensively followed-up. These patients will have haematology (Hb and full blood counts (RBC, WBC and differential count)) and standard biochemistry (BUN, Creatinine, ALT/AST, Bilirubine, electrolytes (K+ and Cl-)) undertaken at Day 1 (before drug administration), Day 3 (3-4 hours after the last dose of treatment), and Day 7. If the results are abnormal and clinically relevant, the blood examination will be repeated until normalization. In all the 1000 patients, a plasma sample will be collected on Day 1 (before drug administration), twice on Day 3 (i.e. before and 3-4 hours after the last drug administration) as well as on Day 7 to assess plasma PQ concentration. From such blood drawings and before centrifugation, three drops of whole blood will be spotted on filter papers. These filter papers will be utilized to determine whole blood piperaquine concentration with the Dry Blood Spot methodology (if a validated analytical method for such determination will be settled up at the time of the study course). ECGs will be undertaken on Day 1 (before drug administration), twice on Day 3 (i.e. before and 3-4 hours after the last drug administration) as well as on Day 7 (ECG on Day 1 and Day 3 after last drug administration will be collected in triplicate); safety information will be collected at all these visits.
If the QTcF (QT corrected by Fridericia's formula) value assessed on Day 3 before last dose is above 500 ms, Eurartesim® should be withheld until QTcF returns below 480 ms within 6 hours. Thereafter, the Eurartesim® cycle may be completed under frequent QTc monitoring based on medical judgment. If the QTcF does not return below 480 ms within 6 hours, another antimalarial therapy should be considered.
The occurrence of any adverse events will be solicited from the subset of 1,000 patients on Days 3 and 7 following administration of Eurartesim® as well as in any additional visits.
All patients in the study with a cardiac event of special interest (see below) will have an ECG performed.
Patients will be asked to report to the health facility or to the HDSS if any adverse event occurs after Day 5 (± 2 days) contact and within 28 days after the start of Eurartesim® intake.
Female patients will be encouraged to communicate to the study team if they get pregnant within a period of two months after the start of the Eurartesim® treatment. In these cases, information on the evolution of the pregnancy will be collected at 3, 6, 9 months and after the delivery (6 and 14 weeks). Information on the drugs taken during the pregnancy as well as AEs/SAEs/AESIs and the health status of the newborn/s will be collected.
Patients will be instructed to take Eurartesim® with a dose regimen of one administration every 24 hours over a period of three days, i.e. at Day 1, then after 24 hours (Day 2) and after 48 hours (Day 3) from the first administration.
The dose will be based on patient body weight. Two strengths of Eurartesim® will be provided to facilitate the dosing in children and adults: 20/160mg and 40/320mg of DHA and PQP respectively.
The patients will be instructed to take Eurartesim® with water, at least three hours before or three hours after food intake (i.e. three hours after the previous food intake with no food intake for the following three hours after Eurartesim® administration).
To facilitate drug administration in small children, tablets will be crushed on a spoon and given with water. If vomiting occurs within 30 min from drug administration, dose will be re-administered. If vomiting occurs within 30 to 60 min, half a dose have to be re-administered. Re-dosing should not be attempted more than once.
