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.

Current Secondary Outcome Measures  ICMJE
 (submitted: March 19, 2018)
  • 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.
  • 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)
  • 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.
  • 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.

Brief Title  ICMJE Etanercept for Treatment of Hidradenitis
Official Title  ICMJE A Phase II Open Label Clinical Trial of Etanercept for the Treatment of Hidradenitis Suppurativa
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.

Detailed Description

Purpose: The primary objective of this study is to determine the safety and estimate the efficacy of etanercept for the treatment of hidradenitis suppurativa. The secondary objective of this study is to determine the impact of etanercept treatment of hidradenitis suppurativa on skin related quality of life.

Duration:

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.

Subject Recruitment and Selection:

It is planned that enrollment will be 12-21 patients.

Background:

Hidradenitis suppurativa is a physically, psychologically, and socially disabling disease characterized by inflammatory, cystic papules and nodules affecting the underarms, groin, perineum, and breasts. Lesions can become erosive and often develop deep abscesses and sinus tracts and drain foul smelling pus. Left untreated, hidradenitis can result in permanent scarring. In the most severe cases, characterized by chronic ulceration and granulation, there may be an increased risk of aggressive squamous cell carcinoma.

Current treatment of hidradenitis consists of intra-lesional injections of steroids, topical and/or systemic antibiotics, hormonal therapy, and isotretinoin. For many patients with severe hidradenitis (stage II and III), these therapies are often ineffective. Patients with stage II and III hidradenitis often require surgical excision of the affected area (a highly morbid procedure) to control the disease. Unfortunately, for most patients with hidradenitis, existing therapies are ineffective and there is an unmet medical need for therapies that control this disabling and destructive disease.

The pathophysiology of hidradenitis is unknown. The leading hypothesis is that occlusion of apocrine ducts leads to severe dilatation, apocrine gland inflammation, with ensuing bacterial growth and neutrophilic infiltration and destruction of the duct. The importance of the immune dysregulation in hidradenitis is further demonstrated by its association in many individuals with inflammatory bowel disease.

The pathologic immune reaction to follicular occlusion in hidradenitis suggests a strong rationale for the use of treatments that may neutralize this inflammatory reaction. In fact, the existing standard treatment of hidradenitis is intra-lesional injections of steroids, in the effort to minimize the destructive nature of the immune response. Medications that are broadly immuno-suppressive, such as cyclosporine, have also been used to successfully treat hidradenitis, but are limited by organ toxicity. This rationale is further supported by case reports of dramatic and rapid (e.g. within days) improvement in hidradenitis treated with infliximab, a monoclonal antibody that blocks TNF-alpha.

Etanercept is a TNF-alpha inhibitor currently FDA approved to treat various inflammatory disorders including rheumatoid arthritis, psoriatic arthritis and psoriasis. By inhibiting TNF-alpha, etanercept stops the inflammatory cascade by binding directly to circulating TNF-alpha and inhibiting its binding to cell surface receptors.

Etanercept has been used in over 200,000 patients world wide for more than 5 years and has a well established safety record. The most common adverse effect of etanercept is injection site reaction which is typically mild and self-limited. Currently, laboratory monitoring for patients being treated with etanercept is not recommended according to its label since the drug has not been associated with a significant incidence of laboratory abnormalities.

The well established safety profile of etanercept and its potent role in suppressing pathologic immune responses through TNF-inhibition make it a promising agent for the treatment of hidradenitis suppurativa. In this phase II clinical trial, we will determine preliminary evidence of safety and estimate the efficacy of etanercept in the treatment of hidradenitis. This study will provide critical preliminary data for planning larger pivotal trials.

Research Design:

This is a phase II, open label, two-stage clinical trial of etanercept for the treatment of hidradenitis. This design is a widely accepted method for early investigations of safety and efficacy of medications for new indications. Etanercept 50 mg will be administered subcutaneously once a week for 12 weeks in an open label manner. At week 12, the etanercept dose will be tapered to 25 mg subcutaneously once a week for 2 weeks.

This is an 18 week study. Subjects will be screened to determine eligibility. Day -95 to -3 will be a screening period which will allow washout of concurrent therapies if necessary.

Potential Risks:

Etanercept was generally well tolerated in patients with rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis. Adverse events that were reported in at least 3% of all patients with higher incidence in patients treated with etanercept than placebo are:

  • Injection site reaction;
  • Infection;
  • Headache;
  • Nausea;
  • Rhinitis;
  • Dizziness;
  • Pharyngitis;
  • Cough;
  • Asthenia;
  • Abdominal pain;
  • Rash;
  • Peripheral edema;
  • Respiratory disorder;
  • Dyspepsia;
  • Sinusitis;
  • Vomiting;
  • Mouth ulcer;
  • Alopecia
