In addition, sexually active FCBP must agree to use TWO of the following adequate forms of contraception while on study medication: oral, injectable, or implantable hormonal contraceptives; tubal ligation; intrauterine device; barrier contraceptive with spermicide; or vasectomized partner while on study. A FCBP must agree to have pregnancy tests every 4 weeks while on study.

Exclusion Criteria:

• Inability to provide voluntary consent
• Any condition, including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study
• Pregnant or breastfeeding
• Systemic fungal infection
• 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.
• Latent Mycobacterium tuberculosis infection as indicated by a positive Purified Protein Derivative [PPD] skin test. Subjects with a positive PPD skin test and documented completion of treatment for latent TB are eligible. Subjects with a positive PPD skin test and not treated or no documentation of completion of treatment are ineligible.
• If QuantiFERON® test is performed instead of the PPD test, only those with a negative QuantiFERON® test are allowed in the study.

• History of incompletely treated Mycobacterium tuberculosis infection as indicated by

  • Subject's medical records documenting incomplete treatment for Mycobacterium tuberculosis
  • Subject's self-reported history of incomplete treatment for Mycobacterium tuberculosis
• History of recurrent bacterial infection (at least 3 major 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 topical cyclosporine, tacrolimus, or pimecrolimus within 2 weeks prior to start of study drug
• Use of systemic or intralesional corticosteroids, systemic retinoids, antimalarials, azathioprine, methotrexate, mycophenolate mofetil, dapsone, thalidomide, sulfasalazine, cyclosporine, metronidazole, griseofulvin, or phototherapy within 4 weeks prior to start of study drug
• Use of etanercept within 8 weeks prior to start of study drug.
• Use of adalimumab or infliximab within 12 weeks prior to start of study drug
• Use of alefacept within 24 weeks prior to start of study drug.
• Use of any investigational medication within 4 weeks prior to start of study drug or 5 pharmacokinetic/pharmacodynamic half-lives (whichever is longer)

• History of congenital or acquired immunodeficiency (eg, 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

• Presence of any other skin condition which may affect the evaluations of the study disease.
• Clinical picture suspicious for lichenoid drug eruption.
• Subjects whose lichen planus is predominantly hypertrophic, follicular, atrophic, or bullous variant.
• Lichen planus involving only mucosa or nails.
