There are about 140 clinical studies being (or have been) conducted in Mozambique. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The primary purpose of this study is to assess the preventive vaccine efficacy (VE), safety and tolerability of a heterologous prime/boost regimen utilizing Ad26.Mos4.HIV and aluminum-phosphate adjuvanted Clade C gp 140 for the prevention of Human Immuno Virus (HIV) infection in HIV-seronegative women residing in sub-Saharan Africa from confirmed HIV-1 infections diagnosed between the Month 7 and Month 24 visits.
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.
This study aims to provide National Malaria Control Programs (NMCP), international donors and other key stakeholders with clear evidence on the impact and cost-effectiveness of using indoor residual spraying (IRS) with a non-pyrethroid insecticide in a high malaria transmission area that has universal long-lasting insecticidal net (LLIN) coverage. This is an interventional study with IRS serving as the research intervention. The district of Mopeia, in the province of Zambezia, Mozambique will be the study site. This is a high transmission area with a malaria parasite prevalence of 54% in children. The Ministry of Health distributed LLINs in Mopeia in 2014-2015. The NMCP through funding from President's Malaria Initiative Africa Indoor Residual Spraying Project (PMI-AIRS) was able to cover half a district with indoor residual spraying. A simplified census took place in mid-2016 to determine the number of children five years of age and under in the district and enumerate and map the households to assist in implementation. From the 115 villages/bairros existent in Mopeia, 86 clusters were randomized in a government randomization ceremony to either receive IRS with Actellic or maintain no IRS. The IRS was implemented through a partnership between the NMCP and PMI-AIRS according to standard operational and consent procedures. From each cluster, a cohort of 18 children five years of age and under will be followed monthly to assess malaria incidence at the community level in both IRS and non-IRS villages. There will be 774 children in the IRS villages and 774 children in the no-IRS villages (total cohort will be 1548). Additionally, the routine health centre reporting system will be strengthened to assess malaria incidence in children five years of age and under by passive case detection. Three cross sectional studies in April 2017, April 2018, and April 2019 will assess changes in net use, health seeking behaviour and malaria prevalence at the community level. Entomological data will be collected from both IRS and non-IRS areas to assess the vector dynamics and insecticide resistance pattern of the local vector populations from sprayed and unsprayed areas. Data on the costs of the implementation as well as health-related expenditures at health system and household levels will be collected prospectively throughout the study. These costs will be determined using both health system and societal perspectives. The incidence rate in IRS and no-IRS areas will be combined with the micro-costing data to calculate the cost per case averted at community and health facility level. These findings will be disseminated to the NMCP and international donors and stakeholders to complement the World Health Organization (WHO) guidance on combining indoor residual spraying and long-lasting insecticidal nets.
This program is a comprehensive evaluation of rheumatic valvular heart disease (RVHD), Atrial fibrillation (AF)/flutter and stroke. A prospective, randomized, parallel group, open-label clinical trial of rivaroxaban versus standard vitamin K antagonists (VKA) therapy to evaluate non-inferiority of rivaroxaban to VKA, with testing for superiority if non-inferiority is satisfied.
A multi-centre, randomized, placebo controlled, trial. Participants at high-risk for vascular events from the network of INTER- CHF will be randomized to inactivated influenza vaccine or placebo and followed prospectively over three influenza seasons. 5,000 participants will be enrolled prior to influenza season, randomized to either influenza vaccine or saline placebo, either of which they will receive annually for three years and then followed over each of the influenza seasons.
One of the proposed ideas for malaria elimination includes the use of drugs to interrupt malaria transmission by exhausting the human reservoir of infection. Theoretically, mass treatment of an entire population with a very effective and rapid-acting drug (for instance an ACT), followed by the administration of an effective prophylactic regime during a minimum of four weeks, so as to outlast the typical development period of Plasmodium parasites in Anopheline mosquitoes, could achieve the same objective. In this respect, chloroquine (CQ) would be an appropriate candidate. This drug exhibits two conditions that make it attractive for elimination campaigns: 1) It has been demonstrated to have an excellent safety profile, allowing for its use in all age groups including pregnant women and children; and 2) Its relatively long elimination half life (t1/2=1-2 months) can provide a long post-treatment prophylactic effect. Recent evidence suggests that CQ sensitivity may be returning in places where discontinuation has reduced the drug pressure to the parasite populations. In countries such as Malawi, P. falciparum seems to have regained full sensitivity to CQ, and molecular markers of antiCQ resistance have nearly disappeared. While this does not support the reintroduction of CQ as first line therapy, it does suggest that, if proven sensitive in a given area, it could play a prophylactic role in malaria elimination strategies when used in combination with other drugs or tools. Thus, we intend to evaluate the potential role of chloroquine in preventing infections during elimination campaigns by performing a randomized, single-blind, placebo-controlled trial in asymptomatic Mozambican adults. Choosing asymptomatic parasitaemic adult males from a malaria-endemic area as our study population introduces limited risks when administering a drug with an uncertain efficacy (47% efficacious in 2001-2002). In malaria-endemic areas, this age group has a remarkably low risk of developing severe disease (irrespective of clinical symptoms), and it is foreseeable that parasitemia may be well tolerated, and in certain cases, spontaneously cleared from the individual's blood as a result of the immune system. In the unlikely event of any clinical symptomatology appearing throughout the follow-up, individuals will be examined by a study clinician and treated immediately with the country's first-line malaria treatment (artemether-lumefantrine, Coartem ®).
Even with optimal anti-malaria therapy and supportive care, severe and cerebral malaria are associated with a 10-30% mortality rate and neurocognitive deficits in up to 33% of survivors. Adjunctive therapies that modify host immune-pathological processes may further improve outcome over that possible with anti-malarials alone. Investigators aim to evaluate a PPARĪ³ agonist ( "rosiglitazone") as adjunctive therapy for severe malaria.
In Mozambique, early infant HIV diagnosis (EID, i.e. HIV screening of infants under 18 months of age) is conducted using molecular diagnostics at central laboratories in Maputo, Nampula, Beira and Quelimane. However, test volumes are growing and many parts of the country do not have close access to laboratories. Test samples are transported over large distances and this can introduce testing delays, especially for patients in rural and remote areas of the country. There are now new POC EID technologies becoming available that will enable diagnosis of HIV in infants within minutes or a couple of hours on site in the clinic, operated by non technical staff and without laboratory infrastructure. This protocol describes a plan to conduct an evaluation of a Point-Of-Care (POC) Early Infant Diagnosis (EID) testing technologies that are being considered for use in Mozambique, and to pilot those technologies in order to provide more effective diagnostics and clinical care to patients. During this implementation pilot, sites are randomized to use either conventional or POC EID testing only before the inclusion of the patients in the study. No consent will be asked to the parents or guardians. A written permission will be asked to the Direção Provincial de Saúde of both provinces to implement the POC device as routine in those intervention sites. All the information that will be analyzed will be collected from the routine care and it will be analyzed as a group.
