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 55 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests nd cardiac monitoring. A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the Investigator considers that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures. The investigator may discuss with GSK medical monitor as required.
  • Male or female between 18 and 55 years of age inclusive: A female subject is eligible to participate if she is of non-childbearing potential defined as pre-menopausal females with a documented tubal ligation or hysterectomy; or postmenopausal defined as 12 months of spontaneous amenorrhoea [in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) greater than 40 MlU/ml and oestradiol less than 40 pg/ml (less than 140 pmol/L) is confirmatory]. Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to discontinue HRT to allow confirmation of post-menopausal status prior to study enrollment. 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 post-menopausal status, they can resume use of HRT during the study without use of a contraceptive method. Male subjects must agree to use one of the contraception methods listed in the protocol. This criterion must be followed from the time of the first dose of study medication until the last follow-up visit.
  • Normal creatinine clearance values at screening (calculated from serum creatinine by a predicting equation using Cockcroft-Gault formula), normal serum creatinine value as defined by the local reference laboratory, normal urine microscopy and no significant proteinuria on dipstick testing.
  • Body weight greater than and equal to 50 kg and BMI within the range 19 - 29.9 kg/m2 (inclusive).
  • No evidence of previous or active TB infection and a negative QuantiFERON TB Gold test taken within 7 days of dosing, and negative medical history with respect to active or latent mycobacterium tuberculosis complex infection.
  • Normal spirometry (FEV1 greater than and equal to 85% of predicted, FEV1/FVC ratio greater than and equal to 70%) at screening. Predictions should be according to ECCS equations, and race corrections should be made for non-caucasians.

About this study

Official title: A Two-part, Randomised, Placebo-controlled Study to Investigatethe Safety, Tolerability, Pharmacokinetics and Pharmacodynamicsof Single Doses of Inhaled GSK1995057 in Healthy Subjects

GSK1995057 is a fully human, single domain antibody directed against the TNFR1 receptor. The purpose of this study is to investigate the safety, tolerability and pharmacokinetics of inhaled GSK1995057 in healthy subjects. The study will be in two parts. Part 1 is a single-dose escalating design of 5 sequential cohorts of healthy subjects. Part 2 is a single-dose, parallel group design comprising 2 groups of healthy subjects assessing the effect of GSK1995057 on lung inflammation following inhaled LPS challenge. Actual dose administered in Part 2 will be determined from emerging safety and PK data from Part 1 and Study TFR110951.

Read the detailed description

This study will be a randomised, placebo-controlled study to investigate the safety, tolerability, pharmacokinetics and pharmacodynamics of single doses of inhaled GSK1995057 in healthy subjects. The study consists of 2 parts with a total of 6 cohorts. Part 1 will be conducted singleblind and Part 2 will be conducted single-blind with restrictions (i.e. subject and investigator only). The GSK Study Team and site pharmacist will remain unblinded to treatment allocation. Cohorts 1, 2, 3 and 4 (in Part 1) will receive a single inhaled dose of GSK1995057 or placebo. Cohort 5 will receive a single inhaled dose of GSK1995057 and in addition will have a bronchoalveolar lavage (BAL) sampling procedure conducted approximately 30 minutes post GSK1995057 dose. Subjects in Cohort 6 (Part 2) will be randomised to receive a high dose of GSK1995057 or placebo followed by an inhaled LPS challenge and BAL sampling procedure. Subjects will be required to visit the clinic over the course of 28 days after their dosing period for a follow up. Further visits for immunogenicity sampling may be conducted at 56 and 84 days post-first dose for subjects who show changes indicating a positive ADA response after dosing. Doses levels stipulated within the protocol are target doses based on predictions using the PK/PD model described in Section 1.2.2 of the clinical protocol. Part 1 will commence first and following acceptable safety and tolerability data will allow initiation of Part 2. All cohorts will participate in a single study session only.

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 10 inclusion and 10 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 27 Jun 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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. 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?

Safety and tolerability of ascending single inhaled doses of GSK1995057 (time frame: 56 Days). The study lists 8 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 NCT01587807, which also lists 2 linked publications.

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 27 Jun 2019.
