An Open Label Study To Investigate the Pharmacokinetics and Pharmacodynamics of Repeat Escalating Doses of the Oral AKT Inhibitor GSK2141795 by 18F FDG PET Analysis in Subjects With Ovarian Cancer

November 7, 2017 updated by: GlaxoSmithKline
The purpose of this study is to explore the potential dose response relationship between the pharmacokinetics of GSK2141795 and [18F] FDG PET pharmacodynamic markers of glucose metabolism in tumor tissue. Three to six subjects will be enrolled in each cohort and dosed with repeat escalating doses of GSK2141795. [18F] FDG PET imaging and optional tumor biopsies will be done prior to initiation of dosing and sequentially at select time points during the first five weeks of dosing. The maximal dose of a given schedule evaluated in this study will not exceed the maximal tolerated dose established in the first-time-in-human trial PCS112689 for the same schedule.

Study Overview

Status

Status

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.

Study Type

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

18 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders 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: Stage 1
Three to six patients on a medium dose of GSK2141795 for four weeks
Drug: GSK2141795
GSK2141795 is an oral, low nanomolar pan-AKT kinase inhibitor that demonstrates activity in hematologic and solid tumor cell lines. It also delays tumor growth in a dose dependent manner in solid tumor xenograft mouse models
Experimental: Stage 2
Nine to eighteen subjects on a low, medium or high dose of GSK2141795 for four weeks
Drug: GSK2141795
GSK2141795 is an oral, low nanomolar pan-AKT kinase inhibitor that demonstrates activity in hematologic and solid tumor cell lines. It also delays tumor growth in a dose dependent manner in solid tumor xenograft mouse models

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
The amount of GSK2141795 in the blood (ng/ml) from baseline
Time Frame: 6 months
6 months

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
Time Frame
The net unidirectional uptake of FDG (Ki) from baseline
Time Frame: 6 months
6 months
The change in size of tumor from baseline (RECIST Criteria)
Time Frame: 6 months
6 months
