Detailed Description
Sarcoidosis is a multisystem disease. Cutaneous involvement occurs in approximately 25% of patients with lesion morphologies varying widely. There is no universally accepted treatment for sarcoidosis. Systemic agents such as oral corticosteroids are frequently necessary for treatment, but long-term therapy is limited by a multitude of serious adverse effects. Steroid-sparing agents such as methotrexate, azathioprine, anti-malarials, pentoxifylline, allopurinol, and thalidomide have been shown beneficial for select patients, but are limited due to significant toxicities of their own or inconsistencies in efficacy.
Infliximab is a chimeric, monoclonal antibody directed against TNF-α and is currently approved by the US Food and Drug Administration (FDA) to treat rheumatoid arthritis, ankylosing spondylitis, and Crohn's disease. Etanercept is a dimeric fusion protein consisting of the extracellular ligand-binding domain of the human TNF receptor linked to the Fc portion of human IgG1. Etanercept has been approved for the treatment of psoriasis, psoriatic arthritis, rheumatoid arthritis, and juvenile rheumatoid arthritis. Treatment with infliximab and etanercept was generally well tolerated and safe in these reports.
To date, there have been no reports describing the treatment of sarcoidosis with adalimumab. Adalimumab (Humira; Abbott Laboratories, Abbot Park, IL) is a fully human, monoclonal antibody directed against TNF-α and is approved by the US FDA to treat rheumatoid arthritis. Given that adalimumab targets the same cytokine as infliximab and etanercept, one would expect that adalimumab may also be effective in the treatment of sarcoidosis. Treatment with adalimumab is advantageous over infliximab through differences in drug delivery. Infliximab is delivered intravenously in the office. This requires routine office visits and vital sign monitoring by a health care professional.
Adalimumab, on the other hand, is administered subcutaneously once weekly or every other week by the patient at home. Patients can be instructed on proper injection technique during one nurse visit. Additionally, because adalimumab is fully human, patients may be less likely to form antibodies against the medication. Because of the lack of alternative safe, effective treatment for sarcoidosis, a clinical trial to evaluate the efficacy of adalimumab in the treatment of sarcoidosis is warranted.

Eligibility Criteria
Criteria
Inclusion Criteria:
-
Subject is willing and able to give informed consent.

Subject is 18 years of age or older.
-
Subject has a diagnosis of cutaneous sarcoidosis for greater than 6 months with a physician global assessment score of at least 4. Diagnosis (based on the recommendations of an expert panel 24) can be made by either:
-
Skin lesions characteristic of sarcoidosis and a biopsy showing granulomas with no evidence of mycobacteria, fungus, or malignancy.
-
A biopsy that does not show granulomas, but the patient has characteristic skin lesions and another clinical feature suggesting sarcoidosis (bilateral hilar adenopathy, erythema nodosum, uveitis, raised ACE level, BAL lymphocytosis (CD4:CD8>3.5), panda/lambda sign on gallium scan)
-
If female of childbearing potential, subject will have a negative urine pregnancy test at Screening and Week 0.
-
If female, subject will be either post-menopausal for > 1 year, surgically sterile (hysterectomy or bilateral tubal ligation), or practicing one form of birth control (abstinence, oral contraceptive, estrogen patch, implant contraception, injectable contraception, IUD, diaphragm, condom, sponge, spermicides, or vasectomy of partner).

-
Platelets > 100 x 10 to the 9th power/L
-
Lymphocytes > 0.5 x 10 to the 9th power/L
