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
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Between 18 and 65 years of age inclusive, at the time of signing the informed consent
  • Confirmed clinical diagnosis of AD according to established criteria by Hanifin at the screening visit.
  • History of AD of at least 6 months.
  • Atopic dermatitis on 15-35%, of the BSA, (scalp and area around the eyes not included as treatment area) at baseline. Note: 1% BSA is approximately equal to the surface of one hand with fingers together (a handprint)
  • An IGA of AD score of >=3 at baseline.
  • Male: Male subjects with female partners of child bearing potential must comply with the following contraception requirements from the time of first dose of study medication until at least five half-lives of study medication after the last dose of study medication:

  • Vasectomy with documentation of azoospermia.
  • Male condom plus partner use of one of the contraceptive options: Contraceptive sub-dermal implant that meets the standard operating procedure (SOP) effectiveness criteria including a <1% rate of failure per year, as stated in the product label; Intrauterine device or intrauterine system that meets the SOP effectiveness criteria including a <1% rate of failure per year, as stated in the product label; Oral Contraceptive, either combined or progestogen alone, Injectable progestogen; Contraceptive vaginal ring; Percutaneous contraceptive patches.
  • These allowed methods of contraception are only effective when used consistently, correctly and in accordance with the product label. The investigator is responsible for ensuring that subjects understand how to properly use these methods of contraception.
  • A woman is eligible to participate if she is of non-reproductive potential, defined as:
  • Postmenopausal (including all women over 60 years of age).
  • Females with one of the following procedures documented and no plans to utilize assisted reproductive techniques (e.g., in vitro fertilization or donor embryo transfer): Bilateral tubal ligation or salpingectomy; Hysteroscopic tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion; Hysterectomy; Bilateral oophorectomy (surgical menopause) Note: A practical definition accepts menopause after 1 year without menses with an appropriate clinical profile (e.g., age appropriate, >45 years, in the absence of hormone replacement therapy [HRT] or medical suppression of the menstrual cycle). In questionable cases for women <60 years of age, a blood sample with simultaneous follicle stimulating hormone and estradiol falling into the central laboratory's postmenopausal reference range is confirmatory. Women <60 years of age who are on HRT, wish to continue, and whose menopausal status is in doubt are required to use a highly-effective method to avoid pregnancy. Otherwise, they must discontinue HRT to allow confirmation of postmenopausal status before study enrollment. For most forms of HRT, at least 2 to 4 weeks will elapse between cessation of therapy and the blood draw; this interval depends on the type and dosage of HRT. Following confirmation of postmenopausal status, HRT may be resumed during the study without use of a highly-effective method to avoid pregnancy
  • Capable of giving signed informed consent as described in Protocol which includes compliance with the requirements and restrictions listed in the consent form and in protocol.

Who cannot join

  • Alanine aminotransferase (ALT) and bilirubin >1.5x Upper limit of normal (ULN) (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%) at screening.
  • Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones)
  • QTc > 450 milliseconds (msec) or QTc > 480 msec in subjects with Bundle Branch Block.
  • NOTES: The QTc is the QT interval corrected for heart rate according to Bazett's formula (QTcB), Fridericia's formula (QTcF), and/or another method, 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 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, QTcB, QTcF, another QT correction formula, or a composite of available values of QTc will be used as specified in the Reporting and Analysis Plan (RAP).
  • Unstable course of AD (spontaneously improving or rapidly deteriorating) as determined by the investigator over the previous 4 weeks prior to dosing (Day 1).
  • Chronic or acute infection requiring treatment with systemic treatments (antibiotics, antivirals, antiparasitics, antiprotozoals, or antifungals) within 4 weeks before dosing, or superficial skin infections within 1 week before the screening visit.

  • A positive drug/alcohol screen at screening.
  • A positive test for Human immunodeficiency virus (HIV) antibody at screening.
  • The subject has participated in a clinical trial and has received an investigational product within the following time period prior to the first dosing day in the current study: 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer).

About this study

Official title: A Pharmacokinetic Study for Systemic Exposure of Twice Daily Topically Applied GSK2894512 Cream in Subjects With Atopic Dermatitis

This study will assess the systemic exposure and pharmacokinetic parameters of GSK2894512 following twice daily topical administration of 1% and 2% cream in adult subjects with AD, and will provide information about the systemic safety as well as local safety and tolerability following twice daily application to up to 35% body surface area (BSA) of affected skin of subjects with AD. It will be an open-label, sequential study consisting of 2 cohorts. A cohort of 6 subjects (Cohort 1) will apply GSK2894512 (cream, 2%) to affected skin on an area ranging from 15 to 35% of the total BSA for 20 days plus a final dose on Day 21. Cohort 2 will consist of 6 subjects that will apply 1% cream. Cohort 2 will follow the same procedures as Cohort 1.

What is being measured

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

  1. Composite of pharmacokinetic (PK) parameters

    PK parameters include plasma concentrations of GSK2894512, maximum observed plasma concentration (Cmax), time to Cmax (tmax), area under the plasma concentration-time curve (AUC) to last measurable concentration [AUC(0-t)], AUC through 24 hours [AUC(0-24)] and AUC per dosing interval [AUC(0-tau)], apparent terminal phase half-life following the last dose (t1/2); steady-state trough concentrations (Ctau), accumulation ratio (Ro), as data allows.

    Measured: On Day 1 at pre-dose, 1 hour (h), 2h, 4h, 8h, 10h, 12h, 14h, 16h; On Days 2, 3, 4, 7 and 14 at Pre-dose; On Day 21 at pre-dose, 1h, 2h, 4h, 8h, 10h, 12h; On Day 22 at 0h

  2. Number of subjects with adverse events (AEs)

    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 temporally associated with the use of a medicinal product

    Measured: Up to Day 22

  3. Safety as assessed by Vital signs

    Vital signs will include height (only at baseline) and weight (only at baseline and Day 22), temperature, systolic and diastolic blood pressure and pulse rate

    Measured: Up to Day 22

  4. Safety as assessed by electrocardiogram (ECG) parameters

    Triplicate 12-lead ECGs will be obtained at each time-point during the study using an ECG machine that automatically calculates the heart rate and measures PR, QRS, QT, and corrected QT (QTc) intervals.

    Measured: Up to Day 22

  5. Safety as assessed by abbreviated physical examination parameters

    Physical examination will include assessments of the skin, lungs, cardiovascular system, and abdomen (liver and spleen).

    Measured: Baseline and Day 22

  6. Safety as assessed by clinical laboratory assessments

    Clinical laboratory assessments will include hematology, clinical chemistry, urinalysis parameters

    Measured: Baseline, Day 7, 14 and Day 22

  7. Local tolerability as assessed by degree of local irritation

    The application sites will be assessed for presence and overall degree of irritation

    Measured: Baseline , Days 1, 2, 3, 4, 7, 14, 21 and 22

Secondary outcomes (5)

  1. Change from baseline in Eczema Area and Severity Index (EASI)

    The EASI scoring system is a standard clinical tool for assessing the severity of AD that takes into account the overall severity of erythema, infiltration/papulation, excoriation, and lichenification, as well as the extent of BSA affected with AD.

    Measured: Baseline (Day -1) and Days 3, 7, 14 and 21

  2. Proportion of subjects with >=50% improvement in EASI

    Measured: Baseline (Day -1) and Days 3, 7, 14 and 21

  3. Proportion of subjects who achieve an Investigator's Global Assessment (IGA) of 0 or 1 and have at least a 2-point improvement over baseline

    IGA is a clinical tool for assessing the current state/severity of the subject's AD.

    Measured: Baseline (Day -1) and Days 3, 7, 14 and 21

  4. Change from baseline in subject's pruritus (numeric rating scale [NRS])

    Subject-reported itch (pruritus) severity will be analyzed by the daily sign and symptom severity diary NRS.

    Measured: Baseline and up to Day 22

  5. Change from baseline in % BSA affected

    Percentage of body surface area (BSA) affected will be assessed at the specified time points.

    Measured: Baseline (Day -1) and Days 3, 7, 14 and 21

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GSK2894512 Topical Cream in people with Dermatitis, Atopic, run by GlaxoSmithKline at 1 site in Canada.

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 13 inclusion and 21 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 Canada. 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?

Composite of pharmacokinetic (PK) parameters (time frame: On Day 1 at pre-dose, 1 hour (h), 2h, 4h, 8h, 10h, 12h, 14h, 16h; On Days 2, 3, 4, 7 and 14 at Pre-dose; On Day 21 at pre-dose, 1h, 2h, 4h, 8h, 10h, 12h; On Day 22 at 0h). The study lists 7 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 NCT02466152, 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.
