NCT ID: NCT03789513 Recruiting - HIV Infections Clinical Trials

Evaluation of Triage Options After HPV Testing for Cervical Cancer Screening Among HIV-infected Women

AIMA-CC
Start date: March 1, 2019
Phase: N/A
Study type: Interventional

Cervical cancer is the most common cause of cancer and a leading cause of death among HIV-infected women living in resource-limited settings. Although screening for premalignant lesions is an effective way of reducing cervical cancer incidence, its uptake in low-resource settings to date is low. The use of HPV testing for primary screening is currently recommended by many guidelines - including the WHO guidelines for cervical cancer screening in resource-limited settings - because of its greater sensitivity and ease of use compared to other options. However, these WHO guidelines have both highlighted the need to conduct more research on appropriate HPV-based algorithms among HIV-infected women, as immunodeficiency may affect the screening performance. Indeed, HPV infections in HIV-infected women are very common, so there is a need for additional triage to identify women most at risk and there remains considerable uncertainty on the optimal option for such triage. Most of the evidence available comes from HIV-negative populations living in high-resource settings and is not necessarily relevant for low-resource contexts where the epidemiological background is different, women access late to screening and may not have follow up visits, where financial constraints are important and health service resources limited. Hence, the proposed project aims to provide evidence on the effectiveness and feasibility of HPV-based screening algorithms among HIV-infected women in low-resource settings. This multicenter cross-sectional study will include 3,000 HIV-infected women (30-49 years old) receiving HAART and followed in Abidjan (Ivory Coast), Bobo-Dioulasso (Burkina Faso) and Phnom Penh (Cambodia). After self-collection of cervico-vaginal samples, each participant will have an HPV test with partial genotyping primary using the Xpert HPV assay, a real-time PCR assay that provides the possibility of identifying 14 HR-HPV types within one hour. The Xpert HPV test has been chosen because of the wide availability of the Genexpert platform in HIV care centers from resource-limited settings. Furthermore, it can specifically detect HPV-16, 18 and 45, the most carcinogenic HPV types in both HIV-negative and HIV-positive women, separately from other high-risk HPV types. VIA will be another triage option either alone or combined to HPV DNA genotyping. In addition, participants treated for cervical lesion will be followed over 12 months to assess the risk of post-treatment lesions (CIN2+/HSIL) and to identify associated risk-factors.

Start date: May 2016
Phase: Phase 3

The purpose of the study is to assess the long-term safety profile of Ad26.ZEBOV and MVA-BN-Filo in participants previously exposed to these vaccines in Phase 1, 2, or 3 clinical studies.

NCT ID: NCT02251704 Recruiting - Malaria Clinical Trials

Epidemiology Study of Malaria Transmission Intensity in Sub-Saharan Africa

Start date: October 22, 2014
Phase: Phase 4
Study type: Interventional

This epidemiology study is planned to run in parallel with the EPI-MAL-002 and EPI-MAL-003 studies, enrolling from the same health and demographic surveillance system (HDSS) (or equivalent system) populations. The co-primary objectives are to produce longitudinal estimates of parasite prevalence in humans, and record malaria control measures usage in areas where EPI-MAL-002 and EPI-MAL-003 studies will take place.

NCT ID: NCT02199951 Recruiting - Malaria Clinical Trials

Introduction of Eurartesim® in Burkina Faso, Mozambique, Ghana and Tanzania

Start date: September 2013
Phase: Phase 4
Study type: Observational

WHO recommends the use of artemisinin-based combination therapies (ACTs) in the treatment of uncomplicated malaria to stem falciparum malaria drug resistance. New ACTs are entering the African market and will be used by the public health care system. The collection of safety data and risk evaluation through observational data are critical in order to assess risk/benefit profile of each ACT through its life cycle and providing information on the best use. Additionally there is need to assess the impact of the introduction of a new ACT in the evolution of its efficacy and malaria morbidity and mortality. Dihydroartemisinin/Piperaquine (DHA/PQP) is a new ACT approved by European Medical Agency and a number of African countries. This is a phase IV observational evaluation of the clinical safety of the fixed-dose DHA/PQP (Eurartesim®) in public health facilities within selected Health and Demographic Surveillance Centres in Burkina Faso (Nouna), Mozambique (Manhica), Ghana (Dodowa, Kintampo, Navrongo), Tanzania (Rufiji) and other African countries to be added. Eurartesim® will be used as first-line treatment of uncomplicated malaria an objective to evaluate the safety of Eurartesim® when used under usual conditions in 10,000 patients. Patients > 6 months and 5 kg except pregnant women will be enrolled and Eurartesim® administered as a single daily dose regimen over 3 days. Patients will be contacted at Day 5 (± 2 days) after treatment, to assess recovery and any adverse events.

NCT ID: NCT01668745 Recruiting - Measles Vaccine Clinical Trials

Trial of Additional Measles Vaccine to Reduce Child Mortality. Burkina Faso.

Start date: May 2013
Phase: Phase 4
Study type: Interventional

Background: All observational studies and a few randomised controlled trials (RCT) suggest that early measles vaccine (MV), in particular an early two-dose strategy, has a much better effect on overall mortality than later MV. These results suggest that MV has a non-measles related beneficial effect on child survival. Objective: To evaluate in a multi-center RCT the effect on child survival and other health indicators of a two-dose measles vaccination schedule by providing an additional dose of Edmonston-Zagreb (EZ) MV as soon as possible after 4 months of age as well as the standard measles vaccine at 9 months of age. Three trials are planned in Guinea-Bissau, Ghana and Burkina Faso. The investigators will test a 40-43% reduction of mortality at each site separately and a 32% reduction overall. Based on the results from the RCT, the investigators will assess the cost-effectiveness of the intervention. Design, Burkina Faso: Newborns are followed through the Health and Demographic Surveillance System (HDSS) of the Centre de Recherche en Sante de Nouna. Information on routine and campaign vaccinations will be collected regularly through home visits and health centre registers. Four weeks after having received the third dose of pentavalent vaccine (Penta3), the children will be eligible for enrollment in the trial if they are not severely ill. Eligible children will be invited to take part in the trial. Provided parental informed consent is given, the children will be randomised to MV at 4 and 9 months of age or only at 9 months. Cost estimates will be based on consumption of services and average cost per unit. The incremental cost effectiveness ratio will be calculated. Sample size, follow-up and analyses: To detect a 43% reduction in overall mortality at each site the investigators intend to enroll at least 4050 children in Burkina Faso. The children will be followed for survival and hospitalisations to 3 years of age or to the end of the study after three years. The investigators will analyse the effects by site and combined; by sex and season; possible interactions with other interventions like campaigns with drugs, vaccines or micronutrients will be explored. Antibody study: 450 children will be enrolled in a subgroup study to examine the effect of maternal antibody levels on subsequent antibody responses to MV. The children will be followed to 24 months of age and samples collected at 4, 9 and 24 months of age.

NCT ID: NCT00452088 Recruiting - Malaria Clinical Trials

A Phase Ib Trial of MSP 3 LSP in 1-2 Year Old Children in Burkina Faso

MSP3LSP
Start date: April 2007
Phase: Phase 1
Study type: Interventional

This will be a study of the safety of MSP 3 LSP candidate malaria vaccine in children aged 1-2 years in Burkina Faso. Three imminizations at 28 day intervals will be administratered subcuteneously on the shoulder region. The study will compare MSP3 with Engerix B vaccine to evaluate whether it is just as safe to give to children in malaria endemic country. The study will also evaluate whether the vaccine induces the expected immune responses. Two dose levels of MSP 3 will be evaluated; 15µg and 30µg to determine the one with the best safety and immune response profile.
