Azithromycin for Child Survival in Niger II
AVENIR II is a cluster-randomized adaptive platform trial designed to evaluate community health interventions in Niger. The initial focus is to monitor under-5 mortality and antimicrobial resistance as the azithromycin MDA for child survival program expands in Niger, with the following specific aims: 1. Mortality. 1. To conduct surveillance of mortality over time compared to the Sustainable Development Goal targets for under-5 mortality reduction. As this intervention is not intended to continue indefinitely, surveillance against a target is needed to determine when to stop. 2. To continue to evaluate the effectiveness of azithromycin MDA to reduce under-5 mortality. Given the risk of AMR, the effectiveness of the intervention over time is needed to fully weigh the risks against the benefits. 2. Antimicrobial Resistance. To determine the impact of azithromycin MDA on AMR in population- and clinic-based samples.

Efficacy, Safety and Tolerability of KLU156 in Adults and Children ≥ 5 kg Body Weight With Uncomplicated P. Falciparum Malaria
The purpose of this study is to confirm the efficacy, safety and tolerability of KLU156 in patients with uncomplicated P. falciparum malaria (with or without other Plasmodium spp. co-infection) by demonstrating that KLU156 is non-inferior to Coartem. - The study duration will be 43 days (Core phase) plus 24 months (Extension phase). - The treatment duration will be 3 days for each malaria episode. - The visit frequency will be Days 1-3 (hospitalized) and 5 follow-up visits (Days 4, 8, 22, 29 and 43) in the Core phase and Days 1-3 (hospitalized) and 3 follow-up visits (Days 4, 8 and 29) in the Extension phase.

Novel Triple-dose Tuberculosis Retreatment Regimen
Stage 1: This is a pragmatic open-label multi-stage randomized clinical trial. Potential participants will be screened and enrolled in Damien Foundation (DF) clinics participating in the trial. First we will perform a two-arm study with 6EHRZ as control arm and 6EH³R³Z as intervention arm. If at interim analysis the intervention arm is not considered to be non-inferior to the control arm, the intervention stops and enrolment will continue in a an adapted intervention arm and the control arm (6EHRZ). Otherwise, enrolment continues to 6EHRZ and 6EH³R³Z. Observational study (stage 2): The DSMB members agreed due to safety concerns to continuing the study as a cohort with only the control arm. The control regimen will remain the same (6EHRZ). As per routine practice, during treatment patients are in daily contact with the direct observed therapy (DOT) supervisor and minimally monthly clinic visits are scheduled for monitoring of safety and treatment response. Additionally, liver function tests will be performed at fixed intervals during treatment. Six month and one year after treatment completion or cure the patient will be checked for relapse with systematic sputum acid-fast bacilli (AFB)-microscopy and TB culture.

A Trial to Compare the Efficacy, Safety and Tolerability of Combinations of 3 Anti-malarial Drugs Against Combina-tions of 2 Anti-malarial Drugs.
Subjects will be randomized to up to four arms: artemether-lumefantrine + amodiaquine, artemether-lumefantrine + placebo, artesunate-mefloquine + piperaquine and artesunate-mefloquine + placebo. As a contingency measure in case of significant differences in the efficacy or safety of one of the combinations being tested and/or study drug expiry or unavailability, subjects may be randomised to 2 arms with a matching ACT-TACT pair, i.e., with artemether-lumefantrine + placebo or artemether-lumefantrine + amodiaquine OR artesunate-mefloquine + placebo or artesunate-mefloquine + piperaquine. Some sites may randomize between 2 arms only with matching ACT-TACT pairs, i.e., artemether-lumefantrine + placebo or artemether-lumefantrine + amodiaquine OR artesunate-mefloquine + placebo or artesunate-mefloquine + piperaquine. In Rwanda, subjects will be randomized between 2 arms consisting of artemether-lumefantrine + placebo or artemether-lumefantrine + amodiaquine. In the control arms, the ACT will be co-packed with a matched (appearance) placebo. In lower transmission settings (Annual Parasite Incidence <50 per 1000 population per year) the treatment will include a single 0.25 mg/kg gametocytocidal dose of primaquine as recommended by the WHO for children ≥10 kg. All drug administrations will be observed. Subjects will be treated in an in-patient unit for 3 days and followed up weekly up to D63. Microscopy to detect and quantify malaria parasitaemia will be performed daily (more frequently in patients with parasite density of >5000/µL at inclusion) during hospitalization, at all weekly and unscheduled visits. A physical examination and measurements of vital signs along with a symptom questionnaire for tolerability will be performed and recorded through a standardized method at baseline, daily during admission and weekly during follow up through D42 and at all unscheduled visits. Physical exam, vital sign measurements and assessments of symptoms will be performed on D49, D56, and D63 only for patients who are parasitaemic or those who report fever or other symptoms. Electrocardiographs will be performed during admission (H0, H4, H52 or H64) and day 42 of follow up to assess and compare the effect of ACTs and TACTs antimalarials on QT or QTc intervals. The DeTACT-Africa Trial is funded by UK Aid from the UK government's Foreign, Commonwealth and Development Office.

Hospital Based Registry of Childhood Cancer in Pediatric Oncology Units in French Speaking Africa
This register is a registration of all children entering hospital based pediatric oncology units, working in selected hospitals in French speaking Africa. The data collected includes: demographic and socioeconomic status as well as clinical status and outcome. The register also collects information on vital status, treatment abandonment and loss to follow-up. Data, collected locally is entered on line using the Research Electronic Data Capture (REDCap) program. Data are stored under the responsibility of the IT department at Gustave ROUSSY in Paris- Villejuif.
