|Condition or disease||Intervention/treatment||Phase|
|Malaria||Drug: GSK932121; Rosiglitazone; Rosuvastatin||Phase 1|
Malaria is a type of parasitic infection, common in tropical and subtropical regions of the world, including parts of the Americas, Asia, and Africa. In recent years there has been a rapid spread of drug resistant malaria which makes it necessary to develop new antimalarial treatments. In animal studies, GSK932121 is shown to be able to kill the malaria parasite and is fully active against drug resistant malaria parasites. It is hoped that information collected on this study will lead to an improved treatment for malaria.
This is a first time in human fusion study which has 3 parts:
Part A - single dose escalation/ food effect: a study where the study drug is given once only- first at the lowest dose of in a group of participants and the dose increased only if the previous dose is found to be safe. It also looks at the effect of food on the study drug in the body Part B - repeat dose escalation: a study where the study drug will be given daily for up to 7 days - first at a lower dose in a group of participants and the dose increased for the next group only if the previous dose is found to be safe and Part B - drug-drug interaction: a study where the study drug will be given daily for up to 7 days at a dose determined to be safe in previous groups of participants and looking at the effect of the study drug on other specific approved medications (such as rosiglitazone--a diabetic medication and rosuvastatin--a cholesterol lowering medication) in the body.
Safety will be assessed by measurement of vital signs, cardiac monitoring, spirometry, collection of adverse event assessments, renal biomarkers and laboratory safety tests.
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||12 participants|
|Intervention Model:||Crossover Assignment|
|Official Title:||A Single-Blind, Placebo-Controlled, Randomized First Time in Human Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of Single and Repeat Dose Escalation of GSK932121 in Healthy Adult Subjects|
|Actual Study Start Date :||December 11, 2008|
|Primary Completion Date :||March 30, 2009|
|Study Completion Date :||March 30, 2009|
Experimental: Single Dose, Repeat Dose, Drug-Drug Interaction
GSK932121 or placebo will be administered as a single dose with or without food in a dose escalation manner. Once the results from the single dose is obtained and reviewed, GSK932121 or placebo will be administered as a repeat dose. The results from each repeat dose level will be reviewed prior to determining the next repeat dose level.
To better understand the effect of GSK932121 on rosiglitazone and rosuvastatin, a drug-drug interaction arm will also be investigated in this study. Rosiglitazone and rosuvastatin will be administered alone, then GSK932121 will be given as a repeat dose. Rosiglitazone and rosuvastatin will then be administered in combination with GSK932121.
Drug: GSK932121; Rosiglitazone; Rosuvastatin
GSK932121 is the study drug that will be tested in all parts of this study as described above. Rosiglitazone and rosuvastatin will only be tested in the drug-drug interaction substudy.
- Evidence of safety as determined by assessing adverse events, vital signs, spirometry, ECGs, telemetry, renal biomarkers, safety labs, and physical examination [ Time Frame: Part A: 3-4 months; Part B: ~1 month ]
- Plasma or blood concentrations of study drug [ Time Frame: Part A: 3-4 months; Part B: ~1 month ]
