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.
Optimizing the prevention of mother-to-child HIV transmission cascade minimizes drop offs from one step to the next to maximize the benefits of antiretroviral therapy on maternal health and pediatric survival, growth, and development. This proposal scales-up a health systems intervention (the systems analysis and improvement approach - SAIA) that packages systems engineering methods (including cascade analysis, flow mapping, and continuous quality improvement) and was previously shown to be effective in improving the prevention of mother-to-child HIV transmission cascade. By spreading the SAIA through routine district management structures, and studying the implementation process, this study will build evidence on how to achieve rapid, sustainable and scalable improvements in services that can dramatically improve population health in resource limited countries.
The purpose of this study is to evaluate the safety and immune response to an HIV clade C vaccine and to an MF59- or alum-adjuvanted clade C Env protein in healthy, HIV-uninfected adults.
The purpose of this study is to evaluate the impact of LUS on the diagnosis and management of childhood pneumonia in developing countries
This study was designed to determine the most effective and tolerable dose at the shortest dosing regimen of the investigational drug KAF156 in combination with a solid dispersion formulation of lumefantrine (LUM-SDF) in adult/adolescent and pediatric patients with uncomplicated Plasmodium falciparum malaria. There is unmet medical need for anti-malarial treatment with new mechanism of action to reduce probability of developing resistance, and for duration shorter than 3 days of treatment and/or reduced pill burden.
The purpose of this R01 proposal is to evaluate the clinical impact, hypothesized mechanisms of behavior change, and cost-effectiveness of a partners-focused integrated elimination of mother-to-child transmission of HIV (EMTCT) package comprised of: 1) antenatal care-based couples HIV testing, ART enrollment, and care for sero-concordant HIV+ expectant couples; (2) Couples-based treatment in the post-partum period; (3) Couple-based education and skills building; and (4) Treatment continuity with the support of expert-patient (peer) supporters from couples who have successfully navigated EMTCT. This innovative approach to scaling up EMTCT services, if proven feasible and effective, will be adopted in President's Emergency Plan for AIDS Relief (PEPFAR) programs to accelerate progress toward EMTCT and helping families with HIV infection live long, healthy lives.
The overall goal of this project is to adapt and assess the impact of a traditional healer training program/intervention on the adherence, retention, and viral load of HIV infected patients newly initiated on anti-retroviral therapy in rural Mozambique.
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.
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.
