Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 65 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Who may be able to join

  • Males aged between 18 and 65 years of age inclusive, at the time of signing the informed consent OR females of non-child bearing potential aged between 18 and 65 years of age at the time of signing the informed consent.
  • Non-childbearing potential defined as:- pre-menopausal females with a documented tubal ligation or hysterectomy, or post-menopausal defined as 24 months of spontaneous amenorrhea [in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) >40 milli-international units (MIU) per millilitre (mL) and oestradiol <40 picograms (pg) /mL (< 140 picomole/liter) is confirmatory. [Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt must discontinue HRT to allow confirmation of postmenopausal status prior to study enrolment. For most forms of HRT, at least 2-4 weeks will elapse between the cessation of therapy and the blood draw; this interval depends on the type and dosage of HRT. Following confirmation of their postmenopausal status, they can resume use of HRT during the study.]
  • Male subjects with female partners of child-bearing potential must agree to use one of the contraception methods listed in Protocol. This criterion must be followed from the time of the first dose of study medication until 5 half-lives after the infusion (Week 16 visit).
  • Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring. A subject with a clinically significant abnormality or laboratory parameter(s) which is/are not specifically listed in the inclusion or exclusion criteria, outside the local reference range being used for healthy volunteers may be included only if the Investigator in consultation with the GSK Medical Monitor agree and document that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
  • White blood cell count >=Lower Limit of Normal (LLN), including both lymphocyte and neutrophil counts >=LLN.
  • Body weight >=50 kilogram (kg) and body mass index (BMI) within the range 19.0 - 32.0 kilogram / square meter (kg/m^2) (inclusive).
  • Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
  • Subjects with a confirmed positive vaccination status for tetanus, diphtheria, pertussis, measles, mumps, rubella, pneumococcus and meningococcus (or consent to vaccination)

Who cannot join

  • Current evidence of ongoing or acute infection within 3 months prior to the first dose of study drug, such as: serious local infection (e.g. cellulitis, abscess); systemic infection [e.g. pneumonia, septicaemia, Tuberculosis (TB)].
  • Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
  • A QT duration corrected for heart rate by Fridericia's formula (QTcF) >450 millisecond (msec) based on either single or averaged QTcF values of triplicate ECGs obtained over a brief recording period.
  • History of regular alcohol consumption within 6 months of the study defined as an average weekly intake of >21 units for males or >14 units for females. One unit is equivalent to 8 grams (g) of alcohol: a half-pint ~240 mL of beer, 1 glass (125 mL) of wine or 1 (25 mL) measure of spirits.

About this study

Official title: A Randomised, Double-Blind (Sponsor Unblind), Placebo-Controlled Study to Evaluate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics and Immunogenicity of Single Ascending Doses of a Fully Humanized Anti-IL-7 Receptor α Monoclonal Antibody (GSK2618960) in Healthy Volunteers

GSK2618960 is a humanized Immunoglobulin G 1 ( IgG1) monoclonal antibody (mAb) that binds to the alpha component (CD127) of the heterodimeric Interleukin-7 receptor (IL-7R). It is being developed for the treatment of autoimmune indications. This study is intended to further explore the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and immunogenicity of single ascending doses GSK2618960 in healthy volunteers beyond those already evaluated in I7R116702 (First Time In Human study). The study is anticipated to enrol 18 subjects in total, with 9 subjects in each of the two cohorts.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GSK2618960 in people with Autoimmune Diseases, run by GlaxoSmithKline at 1 site in United Kingdom.

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 8 inclusion and 18 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 9 May 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 Kingdom. 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 Participants with Adverse events (AE) (time frame: Up to Day 169). The study lists 11 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 NCT02293161, which also lists 1 linked publication.

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 9 May 2017.
