Filter by:The goal of this open label clinical trial will be to assess the therapeutic efficacy of chloroquine plus primaquine in the treatment of uncomplicated plasmodium vivax in Shecha Health Center, South Ethiopia. The main question it aims to answer:- the current therapeutic efficacy of chloroquine plus primaquine in the treatment of uncomplicated plasmodium vivax in Shecha Health Center, South Ethiopia based on clinical, parasitological and hematological parameter. Participants will be patients aged >6 months with diagnosis of plasmodium vivax mono-infection and who fulfills the inclusion criteria. This is a single arm open label invivo therapeutic efficacy study of chloroquine plus primaquine in the treatment of uncomplicated plasmodium vivax. The final result will be compared with World Health Organization recommendation on antimalarial drug therapeutic efficacy.
Comparing the efficacy of the combination treatment of bitter melon fruit extract (Momordica charantia) with primaquine (MC+PQ) against the combination of dihydroartemisinin + piperaquine + primaquine (DHP+PQ) on patients with Plasmodium falciparum and Plasmodium vivax without complications in Manokwari, West Papua, Indonesia. The research was conducted from January 2019 to April 2019 at Manokwari Regional General Hospital, West Papua. Open label, 2 parallel randomized clinical studies with Plasmodium falciparum malaria patients without complications (Study 1) and patients with Plasmodium vivax malaria without complications (Study 2). The randomized clinical trial divided in 2 treatment groups, namely the MC+PQ and DHP+PQ. The Success of the treatment was determined by the combination of blood schizontocidal therapy in radical cure. The overall final assessed results were the average value of parasitological failure, hematological measurements, liver function, kidney function, blood lipid levels, blood glucose levels and adverse events until day 42.
Chloroquine (CQ) is officially used as a first-line drug of Plasmodium vivax malaria in the Philippines. In this study, the therapeutic efficacy of CQ for the treatment of uncomplicated P. vivax malaria in three (3) municipalities (Bataraza, Brooke's Point and Rizal) of Palawan was evaluated using the World Health Organization protocol with a follow-up of 28 days and additional 2 days (Day 31 and 34) for hemoglobin monitoring after primaquine treatment. Study subjects were febrile individuals between > 6 months old and 59 years old with confirmed uncomplicated P. vivax infections. Chloroquine was administered according to body weight at a total dose of 25 mg/kg over 3 days (10 mg/kg on Day 0; 10 mg/kg on Day 1 and 5 mg/kg on Day 2), and primaquine following the National Treatment Guidelines. During the 1 year period that this report covers, there were 8,305 individuals were screened.
The purpose of this prospective, observational study is to assess the operational feasibility of appropriate radical cure treatment for P. vivax malaria with tafenoquine or primaquine, in patients 16 year and older, after G6PD testing in Thailand. The study will be implemented in a phased manner, in the provinces of Yala and Mae Hong Son. The first phase will be at higher level health facilities (hospitals). An interim analysis will be conducted after 40 patients are enrolled in the study in order to decide whether the study could be extended to lower level HFs. If approved by the Independent Study Oversight Committee, the study will be implemented in lower level HFs (malaria clinics).Higher level HFs will continue to include patients in the study during this 2nd phase.Written informed consent / assent is required from all patients /guardians in the case of minors.
This Phase 2a trial recruits adult patients with uncomplicated P. vivax or P. falciparum blood-stage malaria mono-infection. The study drug SJ733 will be administered to examine its antimalarial efficacy, safety, and tolerability. This study also evaluates whether or not a fixed dose of the pharmacoenhancer cobicistat when given in combination with SJ733 significantly improves drug efficacy.
An antimalarial drug efficacy trial was conducted for artemether-lumefantrine (AL) and chloroquine (CQ) in the three (3) municipalities (Bataraza, Brookes and Rizal) of Palawan. Study subjects are febrile individuals between > 6 months old and 59 years old with confirmed uncomplicated P. falciparum or P. vivax infections. Patients with P. falciparum was treated with Artemether-lumefantrine administered 3 days (Days 0, 1 and 2) according to body weight. Primaquine at 0.75 mg base/kg body weight single dose was given on Day 3. For Plasmodium vivax patients chloroquine were administered according to body weight at a total dose of 25 mg/kg over 3 days (10 mg/kg on Day 0; 10 mg/kg on Day 1 and 5 mg/kg on Day 2), and primaquine following the National Treatment Guidelines. During the period that this report covers, 84 and 75 patients met the inclusion criteria for Pf and Pv respectively. Clinical and parasitological parameters were monitored over a 28-day follow-up period for both drugs. The presence of only 1 Late Clinical Failure (LCF) of P. falciparum parasitemia out of 84 enrolled patients and 2 Late Parasitological Failure (LPF) of P. vivax patients out of 75 enrolled patients within the 28 days follow up suggest that both drugs are still efficacious.
This is an open label, Phase IIa, controlled human malaria infection (CHMI) study aimed to assess whether the new vivax malaria vaccines ChAd63 PvDBP and MVA PvDBP can protect against malaria infection. The participants will receive one or two doses of ChAd63 PvDBP followed by one dose of MVA PvDBP 8 weeks later. Approximately 4 weeks after the second vacccination, the volunteers will be challenged (deliberately infected) with malaria by intravenous injection blood-stage
This study is designed as a multi-centre randomized, open label trial to compare the safety and efficacy of a high dose primaquine (PQ) treatment in G6PD normal patients with P. falciparum to reduce the risk of subsequent P. vivax episodes to current standard practice of providing only schizontocidal treatment.
We plan to assess the efficacy of 3 different regimens of chloroquine and primaquine for the treatment of P. vivax infections in Cruzeiro do Sul, Acre, Brazil. Patients will be divided in 3 different groups: treatment with regular dose of primaquine (0.5 mg/kg per day for 7 days) with directly observed therapy; regular dose of primaquine without directly observed therapy; and increased total dose of primaquine (0.5 mg/kg per day for14 days) with directly observed therapy. All patients will receive chloroquine (CQ) for three days at a daily dose of approximately 25 mg/Kg in accordance with the Brazilian National Malaria Control guidelines. Clinical and parasitologic parameters will be monitored over a 28-day follow-up period to evaluate drug efficacy and for a total period of 168 days (24 weeks) to evaluate chances of recrudescence, relapse, or reinfection. Results from this drug efficacy study will be used to assist the Brazilian Ministry of Health in assessing their national malaria treatment policy for P. vivax malaria.
This is a sporozoite-challenge clinical study with the primary aim of assessing the safety and feasibility of controlled human P. vivax malaria infection in two healthy volunteers. The investigators will also assess the growth of and the immune response to P. vivax infection, and assess the induction of sexual gametocytaemia post-CHMI via the natural route of malaria infection (mosquito bite). A secondary objective is to develop a blood inoculum of P. vivax-infected blood for future testing of candidate vaccines.
