A First Time in Human Study in Healthy Volunteers to Investigate a New Medicine to Treat Malaria

August 1, 2017 updated by: GlaxoSmithKline

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

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
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
Part A: 3-4 months; Part B: ~1 month

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
