About this study

Official title: A Multi-centre, Randomised, Double-blind (Sponsor Open), Placebo-controlled, Repeat Dose, Proof of Mechanism Study to Evaluate the Safety and Tolerability, Pharmacokinetics, Pharmacodynamics and Clinical Efficacy of GSK3050002 in Subjects With Psoriatic Arthritis

Chemokine (C-C motif) ligand 20 (CCL20) is a protein involved in attracting immune cells including subsets of T cells (for example Th17 cells), B cells, natural killer cells and dendritic cells to inflamed tissues in conditions such as psoriasis (Ps) and psoriatic arthritis (PsA). CCL20 acts by binding and activating the chemokine receptor 6 (CCR6) present on the surface of the inflammatory cells. Levels of CCL20 are increased in inflamed tissues in psoriasis (Ps) and inflammatory arthritis. GSK3050002 is a humanized Immunoglobulin G (Ig)G monoclonal antibody, which binds to and neutralizes the action of human CCL20. The hypothesis is that GSK3050002 will reduce the movement of inflammatory cells into tissues affected by Ps or PsA, thereby leading to an improvement in disease activity. The primary objective of this multi-centre, randomized, double-blind (sponsor open), placebo-controlled trial is to evaluate the safety and tolerability of repeat doses of GSK3050002, and to understand the mechanism of action (by taking skin and synovial biopsy samples) and potential for clinical efficacy of GSK3050002 in subjects with PsA. A minimum of 18 subjects and up to a maximum of 30 subjects will be randomised into the study to either GSK3050002 or placebo in a 2:1 ratio to ensure that approximately 18 evaluable subjects complete the study. The total duration of participation in the study will be approximately 21 weeks from screening to last study visit.

What is being measured

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

  1. Number of subjects with Adverse Events (AE)

    An AE is any untoward medical occurrence in a clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.

    Measured: Up to Day 116

  2. Number of subjects with Serious Adverse Events

    An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, is an important medical event that jeopardizes the subjects or may require medical or surgical intervention to prevent one of the other outcomes listed in the above definition, and is associated with drug-induced liver injury.

    Measured: Up to Day 116

  3. Composite of clinical laboratory assessments as a measure of safety and tolerability.

    Clinical laboratory assessments will include hematology, clinical chemistry and urinalysis.

    Measured: Up to Day 116

  4. Composite of vital signs as a measure of safety and tolerability.

    Vital signs to be measured in semi-supine position after at least 5 minutes rest and will include temperature, systolic and diastolic blood pressure, and pulse rate.

    Measured: Up to Day 116

  5. Electrocardiogram (ECG) assessment as a measure of safety and tolerability.

    A single 12-lead ECG will be obtained using an ECG machine that automatically calculates the heart rate and measures PR, QRS, QT and corrected QT (QTc) intervals.

    Measured: Up to Day 116

Secondary outcomes (13)

  1. GSK3050002- CCL20 complex levels in serum

    Blood samples will be collected on baseline (Day-10 to -1), at pre-dose and at 120 minutes post start of infusion, immediately after infusion has ceased on D 15 and D 29, D 43, D 85, D 113 +/- 3 days

    Measured: Baseline and Up to Day 116

  2. Change from baseline in the number of CD3+ T cells synovial tissue and skin biopsy in samples

    Synovial and skin lesion biopsy tissue will be collected and evaluated for general appearance and inflammatory infiltrate including CD3+ T-cells

    Measured: Baseline and Day 43

  3. Change from baseline in Disease Activity Score 28 (DAS28)

    DAS28 is a composite arthritis disease activity index comprising swollen and tender joint count (28 joints), patient global assessment of disease activity, and C-reactive protein.

    Measured: Baseline and Up to Day 116

  4. Changes in American College of Rheumatology (ACR) responders

    ACR is a composite score of the patient assessment of joint pain, the patient global assessment of disease activity, the physician global assessment of disease activity, the 66/68 swollen/tender joint count, the Disability Index of the Health Assessment Questionnaire (HAQ-DI) questionnaire, and C-reactive protein. The ACR is reported as % improvement (20%, 50% or 70%), between two discrete timepoints, as calculated by improvement in the 66/68 swollen/tender joint count, and improvement in at least three of the remaining five composite parameters.

    Measured: Baseline and Up to Day 116

  5. Changes from baseline in Psoriatic Arthritis Disease Activity Score (PASDAS)

    PASDAS is a composite disease activity index for psoriatic arthropathies comprising the 66/68 swollen/tender joint count, patient global assessment of disease activity, physician global assesment of disease activity, Leeds enthesitis index, dactylitis score, SF-36 questionnaire and C-reactive protein

    Measured: Baseline and Up to Day 116

  6. Changes in Psoriasis Lesion Severity Score (PLSS)

    The PLSS is the sum of the erythema, scaling and plaque thickness scores.

    Measured: Baseline and Up to Day 116

  7. Changes in Psoriasis Area Severity Index (PASI)

    The PASI scoring system is a widely-used standard clinical tool for assessing the severity of psoriasis that takes into account the overall severity of erythema (redness), thickness (induration), and scale, as well as the extent of body surface area (BSA) affected with psoriasis. Higher scores indicate more severe disease. PASI is a static measurement made without reference to previous scores

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GSK3050002 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 11 inclusion and 23 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: withdrawn, as of the sponsor's last update on 31 Aug 2018. 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 was withdrawn before enrolling participants, so there are no results.

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) (time frame: Up to Day 116). The study lists 5 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 NCT02671188.

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 31 Aug 2018.
