Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Disease severity of Moderate, Severe, or Very Severe by Investigator Global Assessment.
  • Disease severity must be greater than or equal to 6 on the Rajka-Langeland Severity Scoring system corresponding to moderate-severe disease.
  • Baseline EASI score must be greater than or equal to 11. A previous validation study for the EASI scoring system revealed patients with moderate to very severe disease had mean EASI scores ranging from 11-30.
  • Candidate for, or previously on systemic therapy, including cyclosporine, methotrexate, or other immunosuppressant and treatment with ultraviolet light. Specifically, subjects are considered candidates for systemic therapy when their disease is not adequately controlled using topical therapies or side-effects prevent the further safe use of topical therapies.
  • Subjects must meet the washout requirements

Exclusion Criteria:

  • History of active mycobacterial infection with any species (including Mycobacterium tuberculosis) within 3 years prior to screening visit. Subjects with Mycobacterium tuberculosis infection more than 3 years prior to screening visit are allowed if successful treatment was completed at least 3 years prior to randomization and is documented and available for verification.
  • At least 3 major bacterial infections resulting in hospitalization and/or requiring intravenous antibiotic treatment within the past 2 years.
  • Clinically significant abnormality on the chest X-ray (CXR) at screening. Chest X-rays performed within 3 months prior to start of study drug are acceptable.
  • Use of any investigational medication within 4 weeks prior to start of study drug or 5 pharmacokinetic/pharmacodynamic half-lives (whichever is longer).
  • Any clinically significant abnormality on 12-lead ECG (electrocardiogram) at screening.
  • History of congenital or acquired immunodeficiency (e.g., Common Variable Immunodeficiency [CVID]).
  • Hepatitis B surface antigen positive or Hepatitis B core antibody positive at screening.
  • History of Human Immunodeficiency Virus (HIV) infection.
  • Antibodies to Hepatitis C at screening.
  • History of squamous cell carcinoma of the skin and thin melanoma.
  • Systemic corticosteroid-dependent asthma.
  • Active infection of any type at the time of enrollment.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in EASI Scores
Time Frame: Mean change in EASI score measured at Baseline and Month 3, (if on 20mg arm) or Baseline and Month 6 (if on 30mg arm)
The eczema area and severity index (EASI) is a composite score measuring physical signs of atopic dermatitis. The scale ranges from 0-72. The components measuring severity are four signs/symptoms of atopic dermatitis: erythema, population, excoriation and lichenification on a scale of 0-3 for each body of the four body regions (head/neck, trunk, arms, legs). The component measuring area is a body surface area measurement of each region. The area and severity of each body region is weighted based on size of region which are added together for the complete score. The score for each patient's with scores between 0 and 7 are considered mild ,between 7 and 21 are considered moderate, and greater than 21 are considered severe. In this study the change in EASI score between baseline and month three (end of study) in the 20 mg arm and month six in the 30 mg arm, baseline EASI score was subtracted from month 3 or month 6 score in the 30mg arm,and calculated as a final outcome data point.
Mean change in EASI score measured at Baseline and Month 3, (if on 20mg arm) or Baseline and Month 6 (if on 30mg arm)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants in Each IGA Category
Time Frame: Mean change in IGA score measured at Baseline and Month 3, (if on 20mg arm) or Baseline and Month 6 (if on 30mg arm)
The investigator global assessment scale is a gestalt global assessment made by an investigator describing the overall disease severity of the patient. It is a categorical scale that includes 0-clear, 1-almost clear, 2-mild,3- moderate, 4-severe, and 5-very severe. The reduction in IGA score from baseline to month three (end of study) in the 20mg arm and month six (end of study) in the 30mg arm was evaluated for efficacy.
Mean change in IGA score measured at Baseline and Month 3, (if on 20mg arm) or Baseline and Month 6 (if on 30mg arm)
Change in Pruritus (Visual Analog Scale) Score
Time Frame: Mean change in Pruritus (Visual Analog Scale) score measured at Baseline and Month 3, (if on 20mg arm) or Baseline and Month 6 (if on 30mg arm)
The pruritus visual analog scale (VAS) is a 10 cm (100 mm) visual analog scale that measures up patient's itch severity with 10 (100 mm) representing the worst imaginable and 0 representing no itch. This is a validated scale with a change of three from baseline to month three in the 20mg arm (end of study) and month six in the 30mg arm (end of study) being clinically relevant.
Mean change in Pruritus (Visual Analog Scale) score measured at Baseline and Month 3, (if on 20mg arm) or Baseline and Month 6 (if on 30mg arm)
Change In DLQI Scores
Time Frame: Mean change in DLQI scores measured at Baseline and Month 3, (if on 20mg arm) or Baseline and Month 6 (if on 30mg arm)
The dermatology life quality index (DLQI) is a validated quality-of-life scale that measures the impact of skin disease. It is a 10 question instrument. Scores of 0 over 0-1 means there is no effect on the patient's life. Scores between 2 and 5 represent a small effect on patient's life. Scores between 6 and 10 correspond to a moderate effect on patient's life. Scores between 11 and 20 correspond to a very large effect on the patient's life. And scores between 21 and 30 correspond to an extremely large effect on patient's life. The range of the scale between 0 and 30 for the added total of the patient's responses. Each question can be answered on a scale of 0-"not at all", 1-"a little", 2-" a lot", 3- "very much" with some questions having the option of "not relevant". The difference in DLQI score from baseline to month three (end of study) in the 20mg arm and month six (end of study) in the 30mg arm was evaluated for efficacy.
Mean change in DLQI scores measured at Baseline and Month 3, (if on 20mg arm) or Baseline and Month 6 (if on 30mg arm)
