Brief Summary:

This study is being done to test a drug called etanercept (Enbrel®). Etanercept has been approved by the U.S. Food and Drug Administration (FDA) for the treatment of chronic moderate to severe plaque psoriasis (PsO), for use in reducing the signs and symptoms of moderately to severely active rheumatoid arthritis (RA) in adults and children, and psoriatic arthritis (PsA) and ankylosing spondylitis (AS) in adults. It is available by prescription for the treatment of PsO, RA, PsA, and AS. Etanercept is approved for injection under the skin at a dose of 50 mg per week in patients with psoriasis.

The purpose of this study is to determine whether etanercept is safe and effective for the treatment of hidradenitis. Another purpose of this study is to determine the impact of etanercept treatment of hidradenitis on skin related to quality of life.

The skin lesions typically associated with hidradenitis are thought to be partly due to a blockage that occurs in sweat glands, called apocrine ducts, which become inflamed and eventually destroyed. A protein found in the body called tumor necrosis factor alpha, or TNF- α, is a hormone that causes this inflammation or swelling. The study drug, etanercept, blocks the action of TNF- α. By blocking the action of TNF-α, etanercept may provide a reduction in the signs and symptoms of hidradenitis.

This study will take place at the University of Pennsylvania and will involve up to 21 participants ages 18 and up. Approximately 21 subjects will participate at the University of Pennsylvania.

Each patient will participate in this study for a maximum of 6 months. The study consists of a screening visit, baseline assessment visit (Day 1), a treatment period (Week 2 - Week 14), and a one month follow-up visit (Week 18 visit). The total duration of the study will be approximately 2 years.

Primary Outcome Measures :
  1. 50% Reduction in Physician's Global Assessment Score (Percent of Participants) [ Time Frame: 12 weeks ]

    Efficacy was measured using the Physician Global Assessment (PGA). Responders were classified as those achieving at least a 50% reduction on the Physician Global Assessment score at week 12 compared with baseline. A response rate was calculated as the percentage of patients that were classified as responders at 12-weeks.

    PGA was scored at baseline and at 12 weeks on a 100-mm visual analog scale, with 0 indicating no disease and 100-mm indicating severe disease.



Secondary Outcome Measures :
  1. 50% Reduction in Number of Lesions (Percent of Participants) [ Time Frame: 12 weeks ]
    A physician assessed number of lesions as baseline and week 12. Responders were defined as those achieving at least a 50% reduction in number of lesions. A response rate was calculated as percentage of patients classified as responders.

  2. Patient Global Assessment [ Time Frame: 12 weeks ]

    The Patient Global Assessment asked patients to rate the extent of hidradenitis activity compared to when the patient started treatment with etanercept (day 0 of study). The scale included a selection of:

    Much worse than before treatment Moderately worse (about 50% more disease activity) A little worse Same A little improved Moderately improved (about 50% reduction in disease activity) Much better than before treatment (no active disease or almost no active disease)


  3. Patient's Pain Score [ Time Frame: 12 weeks ]
    Patient's were asked to self-report their pain on a 100-mm visual analog scale (with 0 corresponding to no pain and 100 mm corresponding to severe pain). Responders were defined as those achieving at least a 50% reduction in pain score from baseline to week 12. Response rate was calculated as the percentage of patients classified as responders.

  4. Dermatology Life Quality Index Score (DLQI) [ Time Frame: 12 weeks ]

    The DLQI is a dermatology-specific health-related quality of life measure. The effect on a patient's life is as follows: 0-1=none; 2-5=small; 6-10=moderate; 11-20=very large; and 21-30=extremely large. Responders were defined as those who achieved a 50% improvement in the DLQI score.

    Response rates were calculated as the percentage of participants achieving a response.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Subjects must be able to give informed consent.
  • Severe hidradenitis suppurativa clinically confirmed by the investigator and defined as recurrent abscesses, with 4 or more lesions (e.g. nodules or abscesses) with sinus track and scar formation (e.g. Stage II or III disease) that has not responded to previous standard therapies such as topical or oral antibiotics, or intralesional injections of steroids.
  • Age 18 or older.
  • Willingness to use at least one form of effective contraception during the study period and for one month after discontinuation of etanercept if female and of child bearing capacity or if male. If the patient elects to use a hormonal form of contraception then the patient must be on the same form of hormonal contraception for 90 days prior to the start of Etanercept and must plan to continue using the same form of hormonal contraception for the duration of the study (e.g. until week 18).

Exclusion Criteria:

  • Use of oral or topical antibiotics, isotretinoin, or intralesional steroids within 30 days prior to day 0 or at any time during the study treatment period.

  • Use of an investigational medication 90 days prior to day 0 of this study.
  • Use of a live vaccine 90 days prior to day 0 of this study.
  • Any previous use of TNF- α inhibitors.
  • If using a hormonal form of contraception, the patient will be excluded if they have not used the same form of hormonal contraception for 90 days prior to the start of the etanercept (e.g. day 0) or are not willing to continue the use of the same form of hormonal contraception for the duration of the study.
