Who may be able to join

  • Participant must be 20 to 64 years of age inclusive, at the time of signing the informed consent
  • Participants who are overtly healthy as determined by medical evaluation including medical history, physical examination, laboratory tests, and cardiac monitoring. A subject with a clinical abnormality or laboratory parameter(s) which is/are not specifically listed in the inclusion or exclusion criteria, outside the reference range for the population being studied may be included only if the investigator in consultation with the Medical Monitor if required agree that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures

  • QTcF >450 millisecond (msec) QTcF is either machine-read or manually over-read. The specific formula that will be used to determine eligibility and discontinuation for an individual subject should be determined prior to initiation of the study. In other words, several different formulae cannot be used to calculate the corrected QT interval (QTc) for an individual subject and then the lowest QTc value used to include or discontinue the subject from the trial. For purposes of data analysis, QTcF, another QT correction formula, or a composite of available values of QTc will be used
  • Past or intended use of over-the-counter or prescription medication including herbal medications within 14 days prior to dosing. Specific study-defined medications may be allowed

About this study

Official title: A Single Centre, Double-blind, Randomised, Placebo-controlled, and Single Dose-ascending Study to Investigate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics, of Single Intravenous Doses of GSK2315698 in Healthy Japanese Subjects

This is the first study in which GSK2315698 will be administered in Japanese population. The primary objective of the study is to investigate safety and tolerability, pharmacokinetics, and pharmacodynamics after single intravenous infusion in healthy subjects. This will be a single center, double-blind, randomized, placebo-controlled, dose-ascending study.

Subjects in Cohort 1 will attend 3 dosing sessions, and will be randomized to one of the 3 groups. Each group will receive GSK2315698 and Placebo in a defined sequence. The dose levels of GSK2315698 are set to 10 milligrams (mg) per hour (hr), 20 mg/hr, and 40 mg/hr, to be administered over 1 hour. Dosing sessions 1 and 2, and dosing sessions 2 and 3, will be separated by a washout period of at least 8 and 10 days, respectively.

Subjects in Cohort 2 will attend a single dosing session, and will be randomized to receive either GSK2315698 20 mg/hr or Placebo, over a period of 15 hours.

A sufficient number of subjects will be randomized such that 18 subjects (9 in each cohort) complete the study. The duration of participation for any subject in this study will be approximately 59 days.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GSK2315698 in people with Amyloidosis, run by GlaxoSmithKline at 1 site in Japan.

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 6 inclusion and 16 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 19 Jan 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 Japan. 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?

Number of subjects with adverse events (AE) and serious adverse events (SAE) (time frame: Over a maximum period of approximately 29 days). 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?
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 19 Jan 2017; AzTrials last refreshed its copy on 8 Nov 2026.
