Active clinical trials for "Malaria"

The primary objective of this clinical study is to compare the efficacy and safety of the fixed combination of pyronaridine artesunate (180:60 mg) with that of standard chloroquine therapy in children and adults with acute, uncomplicated Plasmodium vivax (P. vivax) malaria

The present proof-of-concept Phase IIa study aims to confirm, in patients, the observed activity of MMV390048 against P. falciparum in pre-clinical models and the human Induced Blood-Stage Malaria (IBSM) challenge model, and to determine the activity against P. vivax malaria in patients, both over 14 and 28 days. Additional aims are to characterise the safety of MMV390048 in patients. Patient safety will be monitored for up to 35 days post-dose including pharmacokinetic assessments. The study will investigate descending single doses of MMV390048 in response to results obtained in the first cohort/dose in each malaria sub-type. The results of this trial will identify active, well-tolerated doses for investigation in combination with a partner drug within a Phase IIb clinical trial.

This is a single-center open label study conducted in multiple sequential cohorts using Induced Blood Stage Malaria infection in healthy volunteers to characterize the effectiveness of KAE609 against sexual and asexual blood stage forms of Plasmodium falciparum. This study is divided in 2 parts (Part A and part B). A total of 8 healthy volunteers per cohort will be enrolled. Based on the results of Part A, Part B will be undertaken to evaluate the effect of KAE609 following pretreatment with Piperaquine on sexual stage/gametocytemia and its activity as an inhibitor of onward transmission to mosquito vectors using experimental mosquito feeding assays.

The purpose of this study is to evaluate the tolerability and safety of increasing doses of primaquine in combination with dihydroartemisinin-piperaquine in G6PD deficient males.

Primary Objective: To assess the antiparasitic activity of intramuscular (IM) SAR97276A based on parasite reduction ratio at 72 hours in pediatric patients with uncomplicated malaria Secondary Objectives: To assess the evolution of clinical signs and symptoms (including the need for a rescue therapy) in pediatric patients with uncomplicated malaria receiving SAR97276A with reference to Artemisinin-Based Combination Therapy (ACTs) To assess the pharmacokinetics profile of SAR97276A in pediatric patients with uncomplicated malaria To assess the safety profile of SAR97276A in pediatric patients with uncomplicated malaria To assess the pharmacokinetic-pharmacodynamic relationship of SAR97276A

Primary objective: To assess the Day 28 efficacy defined as the percentage of patients with no parasitic recrudescence, of 3 treatment groups - 3 dose levels of ferroquine associated with artesunate - for a 3-day treatment. Secondary objectives: To assess the efficacy of ferroquine at one dose level alone for a 3-day treatment. To assess the clinical safety of 4 treatment groups - 3 dose levels of ferroquine associated with artesunate and one dose level of ferroquine alone. To assess pharmacokinetics parameters of ferroquine and its metabolites along sparse sampling schedules.

The purpose of this study is to determine if the study drug (antimalarial medication) is safe when given to healthy subjects as a single dose or as repeated doses, to understand the effect of food on single doses of study drug and to determine if the study drug has an effect on other approved medications such as rosiglitazone and rosuvastatin.

Malaria remains a major cause of morbidity and mortality particularly among children < 5 years in Uganda. Due to inaccessibility many children die before they reach the health facility. The Home Based Management of Fever (HBMF) strategy was adopted in Uganda as a mean to improve access to early and appropriate treatment of fever at community level. Pre-packed chloroquine with sulphadoxine-pyrimethamine (HOMAPAK) is provided through Community Drug Distributors(CDDs). Initial evaluation showed underutilization of the CDDs (15%). This cast doubt on community acceptability, accessibility as well as its feasibility and cost effectiveness. This 3-year project intends to compare community acceptability and cost effectiveness of two HOMAPAK distribution methods. The current CDD-based HOMAPAK distribution versus home-based HOMAPAK distribution. The study hypothesis is that "home-based HOMAPAK distribution is more acceptable to the community and more cost effective than the CDD based HOMAPAK A non randomised community study will be conducted in two sub-counties of Mukono district. In the control arm, HOMAPAKs will be distributed through the CDDs while in the intervention arm, HOMAPAKs will be directly distributed to the caretakers in the homes. The study population are caretakers and their children < 5 years. At baseline a survey (Phase 1) with a sample size 657 in each study area will assess the common drugs stocked at home to treat malaria and the health seeking behaviour for malaria for children < 5 years and to determine the prevalence of malaria parasitaemia and anaemia among children < 5 years. Phase 2 includes the intervention. The villages will be assigned to either the control or intervention arm. Anaemia and malaria parasitaemia among children with fever will be assessed through active case finding. The impact of either distribution system on accessibility, acceptability, sustainability, compliance, cost effectiveness and malaria morbidity will be assessed during the evaluation phase. Health education messages on malaria prevention and treatment will be given to both communities. Drug misuse will be limited by distributing HOMAPAKs according to the number of children <5years in each household. HOMAPAK will only be replenished after the caretaker returns a used packet to the CDD.

Part A -Cohort 1 DSM265 will be administered as a single dose (400 mg). For cohort 1 only, an additional single dose (400 mg) of DSM265 may be given if gametocytemia develops. Treatment with DSM265 will be given after an overnight fasting period of ≥ 8 hours. If dosing is to occur in the evening, subjects will be required to fast for ≥4 hours prior to receiving treatment. Subjects will be required to fast for a further four hours anytime after dosing with DSM265. Part B Cohort 2 OZ439 will be administered as a single 200 mg dose. If recrudescence is observed, a single 400 mg dose of OZ439 will be given. Treatment with OZ439 will be administered after an overnight fasting period of ≥ 6 hours. If dosing is to occur in the evening, subjects will be required to fast for ≥4 hours prior to receiving treatment. Participants will drink 200 mL of milk prior to drug administration, and then swallow the appropriate volume of OZ439 suspension. Subjects will be required to fast for a further six hours anytime after dosing with OZ439. Cohort 3 DSM265 will be administered as a single dose (400 mg) as described for cohort 1. No additional dose will be administered.

This is a phase 1 trial to evaluate the safety and pharmacokinetics of single and multiple ascending doses and effect of food on the pharmacokinetics of a novel antimalarial drug in healthy adults. The study will enroll 104 healthy volunteers, males and females, aged 18 to 45 years and will consists of 3 parts: Part 1, Single Ascending Dose (SAD); Part 2, Multiple Ascending Dose (MAD); and Part 3, Food Effect. Part 2 and Part 3 may be initiated after a Safety Monitoring Committee (SMC) review and approval of the of Part 1 safety data. Study duration will be 16 months with patient participation duration 14 days for SAD and Food Effect, and 18 days for MAD. The primary objectives of this study are to: 1) assess the safety and tolerability of single doses of DM1157 at levels ranging from 9 mg to 900 mg; 2) assess the safety and tolerability of DM1157 administered as single daily doses for 3 days at levels ranging from 150 mg to 900 mg; 3) assess the safety and tolerability of DM1157 administered with or without food.
