About this study

Official title: A Randomized Double-blind (Sponsor Unblind) Placebo Controlled Study in Healthy Subjects to Evaluate: Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of the Repeat Doses of GSK2881078, the Selective Androgen Receptor Modulator With an Open Label Dosing Arm to Evaluate the Effect of CYP3A4 Inhibition on Pharmacokinetics of GSK2881078

GSK2881078 is a selective androgen receptor modulator (SARM) that is being evaluated for effects on muscle growth and strength in subjects with muscle wasting to improve their physical function. Part A of this study will evaluate the safety, efficacy and pharmacokinetics of GSK2881078 in healthy, older men and post-menopausal women who will take daily dosing for 28 days and be followed for a total of 70 days. Part B of this study will characterize the effect of Cytochrome P450 3A4 (CYP3A4) inhibition on the GSK2881078 pharmacokinetics. Part B will only be conducted if safe and efficacious dose is identified in Part A. Part A will include healthy older males and post-menopausal females; and randomize approximately 60 subjects (about 15 per cohort [4 cohorts]) to complete approximately 48 (about 12 per cohort). Part B will enroll one cohort of approximately 15 healthy male subjects to complete approximately 12. The study duration will be approximately 115 days for Part A and 122 days for Part B.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Part A: Blood pressure as a measure of safety and tolerability

    Blood pressure will be recorded whilst the subject is in a semi -supine position, having rested in this position for at least 10 minutes.

    Measured: Up to Day 70

  2. Part A: Heart rate as a measure of safety and tolerability

    Heart rate will be recorded whilst the subject is in a semi -supine position, having rested in this position for at least 10 minutes.

    Measured: Up to Day 70

  3. Part A: Cardiac telemetry as a measure of safety and tolerability

    Continuous cardiac telemetry will be performed for at least 8 hours post-dose.

    Measured: Up to Day 28

  4. Part A: Electrocardiogram (ECG) as a measure of safety and tolerability

    Triplicate or single 12-lead ECGs will be obtained at each timepoint and will be recorded whilst the subject is in a semi-supine position, having rested in this position for at least 10 minutes.

    Measured: Up to Day 70

  5. Part A: Composite of clinical laboratory parameters including hematology, clinical chemistry, and lipid blood panel (fasting) as a measure of safety and tolerability

    Measured: Up to Day 70

  6. Part A: Number of subjects with adverse events (AEs)

    An AE is any untoward medical occurrence in a patient or clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product.

    Measured: Up to Day 70

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GSK2881078 and Itraconazole in people with Cachexia, run by GlaxoSmithKline at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 25 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Part A: Blood pressure as a measure of safety and tolerability (time frame: Up to Day 70). The study lists 13 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02567773.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Mar 2017; AzTrials last refreshed its copy on 8 Nov 2026.
