Filter by:This is an individually randomized, controlled, single blind four arm clinical trial of malaria chemoprevention strategies Arm 1: Intermittent preventive treatment with dihydroartemisinin-piperaquine (IPT-DP). Arm 2: Intermittent preventive treatment with sulfadoxine-pyrimethamine (SP) plus chloroquine (CQ) (IPT-SPCQ). Arm 3: Intermittent preventive treatment with sulfadoxine-pyrimethamine (SP) plus amodiaquine (AQ) (IPT-SPAQ).Arm 4: Control - students will receive standard of care (no preventive treatment). Outcomes include P. falciparum infection and parasite density, anemia, cognitive function and educational testing, as well as infection prevalence and disease incidence in young children sleeping student's households to assess the impact on transmission.
This will be a double-blind, individually randomised trial, to assess the safety, tolerability, immunogenicity, and protective efficacy of two and three doses of the R21/Matrix-M1 malaria vaccine or placebo given at 4 week intervals in healthy women of childbearing potential (WOCBP), who are on pregnancy prevention during vaccination, but report plans to become pregnant in the near future. Participants will be randomised in Year 1 into three groups in a 1:1:1 ratio: - Arm 1 (n=110): will receive three doses of R21/Matrix-M1 malaria vaccine at months 0, 1 and 2. - Arm 2 (n=110): will receive normal saline (placebo) at month 0 and two doses of R21/Matrix-M1 malaria vaccine at months 1 and 2. - Arm 3 (n=110): will receive three of doses normal saline (placebo) at months 0, 1 and 2. In Year 2: Non-pregnant participants in arms 1 and 2 will be randomised in a 1:1 ratio to receive a booster dose of R21/Matrix-M1 malaria vaccine or placebo at the beginning of the malaria transmission season. Participants in the control group (arm 3) will receive normal saline (placebo). Initial follow-up will be for two years after dose three, with an efficacy analysis at 6, 12, 18 and 24 months after dose 3. Participants will be monitored for safety, tolerability, immunogenicity, and malaria infection during the follow-up period. Participants will also be monitored for pregnancy over 12 months post primary and booster vaccination and those who become pregnant will be followed during their pregnancy and for 1 year post-delivery (as well as their offspring) for safety and malaria infection
This is an open i.e. not blinded, cluster-randomised, controlled intervention study. The study will use a factorial design to estimate the protective effectiveness of mass drug administrations, mass vaccinations, combined mass vaccinations and drug administrations versus the current standard of care.
This phase 2a open-label study to assess Meplazumab in adult patients diagnosed with Plasmodium falciparum
The goal of this open-label randomised, controlled, non-inferiority trial is to assess and compare the efficacy, tolerability and safety of a fixed dose TACT artemether-lumefantrine-amodiaquine (ALAQ) to the ACTs artemether-lumefantrine (AL), artesunate-amodiaquine (ASAQ) (with single low-dose primaquine in some sites) for the treatment of uncomplicated Plasmodium falciparum malaria in patient. The main question it aims to answer is whether ALAQ, a fixed dose TACT, is as efficacious, safe and tolerable in comparison with AL and ASAQ. Participants will be enrolled, admitted and randomised to receive the study drug (ALAQ, AL or ASAQ). Patients will receive directly observed treatments and will be followed up at least once daily for the first 3 days after enrolment followed by weekly visits from D7 up to D42. Patients will be asked to report to the clinics between scheduled visits in case of any illness or other symptoms or complaints.
There are few safe, effective, and affordable interventions to improve pregnancy outcomes in low resource settings where the highest rates of poor birth outcomes occur. L-citrulline is naturally found in many foods and is changed into another important amino acid, L-arginine, in the body. L-arginine is important for the growth of a healthy placenta and healthy baby. Adding L-citrulline to the diets of pregnant women may be an effective and affordable way to improve the health of their babies.The goal of the AGREE trial is to test whether a dietary supplement containing a common food component, an amino acid called L-citrulline, can help pregnant Kenyan women at risk of malaria have healthier pregnancies and healthier babies. 2,960 pregnant Kenyan women will be enrolled and randomly assigned to take either a twice daily dietary supplement containing L-citrulline or a placebo supplement without additional L-citrulline. Maternal participants will be seen every month until delivery and at weeks 1 and 6 after birth. Infants will also be followed up at ages 6, 12, 18, and 24 months. The primary outcome of the study is 'adverse pregnancy outcome', a composite of foetal loss (miscarriage or still birth), preterm birth, low birth weight, small for gestational age or neonatal mortality. The results of the AGREE trial could help to guide obstetric and public health policy and provide a sustainable solution that could be implemented at the community level.
The main purpose of this study is to evaluate the safety and effectiveness of Plasmodium immunotherapy in the treatment of advanced ovarian cancer. This study plans to enroll 30 patients with advanced ovarian cancer. Each patient is inoculated with Plasmodium vivax 1-5 × 10^6, observe the time when the parasite is detected in the peripheral blood of the subjects after the inoculation of Plasmodium, the change of the parasite density in the peripheral blood of the whole treatment cycle and the control effect of the drug on the parasite density, the main clinical symptoms and signs, laboratory test indicators, immunological test indicators and changes in the quality of life. To evaluate the safety and tolerance of the subjects to Plasmodium immunotherapy, as well as the changes of tumor related indicators and immunological indicators.
Malaria is caused by protozoan parasites of the genus Plasmodium and it is the most important parasitic disease in terms of mortality and morbidity. Estimates of 247 million malaria cases and 619.000 deaths worldwide were reported by WHO for the year 2021 (1). Plasmodium falciparum can lead to severe malaria and accounts for 90% of malaria deaths that mainly occur in children below the age of 5 years in Sub-Saharan Africa. A simplified treatment regimen, ideally a single-day cure (or at most 2-day dosing regimen), of uncomplicated malaria due to P. falciparum would be the magic in the antimalarial armamentarium. Improving treatment adherence is one of the key factors in reducing mortality and morbidity and also the transmission of malaria, and such a regimen would substantially increase adherence. To find a new non-artemisinin combination therapy with a shorter regimen, ideally, a single-dose cure, with low resistance potential would be the aim. The two compounds tested here are ZY19489, a triaminopyrimidine, and ferroquine (FQ), a next-generation 4-aminoquinoline. Both compounds show unique features in terms of long half-life, and activity against current drug-resistant strains. Therefore, the main goal of this clinical trial is to assess the safety of the ZY19489-FQ combination given as a 1- or 2-day dose regimen.
Malaria is still responsible for more than 627,000 deaths each year, predominantly among children under 5 years old. Current reductions in deaths have stagnated, and additional setbacks for malaria control programs due to the Coronavirus Disease 2019 (COVID-19) pandemic are expected. To achieve malaria elimination and eradication a leverage concerted approaches to reduce clinical disease and prevent new infections is a must. The existing malaria controls tools including the a recombinant protein-based malaria vaccine (RTS,S ,(trade name MosquirixMosquirix )), a malaria vaccine currently undergoing implementation studies and endorsed by the World Health Organization on October 7, 2021, can reduce disease burden for patients but cannot ultimately support malaria elimination and eradication since their effect on malaria transmission is at most partial. Consequently, complementary interventions, such as transmission-blocking vaccines (TBVs) may prove to be a cost-effective intervention that can reduce on-going residual transmission and the cascade of new infections.
The investigators believe that to effectively achieve malaria elimination in Rwanda, it is critical to target the human reservoirs of Plasmodium falciparum using local and readily available Artemisia tea. Asymptomatic infections detectable by PCR are important reservoirs because they often persist for months and harbor gametocytes, the parasite stage infectious to mosquitoes. Lessons learnt from this study will be of critical importance for health decision makers with regard to potential malaria control. MSc and PhD students will be trained and the impact of this research project will be enormous on the socioeconomic transformation of Rwanda.
