Brief Summary:

This study will evaluate the safety and effectiveness of thalidomide in treating Sjogren's syndrome. In this autoimmune disease, the immune system attacks the body's tear glands and salivary glands, causing dry mouth and dry eyes. Thalidomide has shown promise in treating other autoimmune disorders, such as rheumatoid arthritis and systemic lupus erythematosus.

Women with Sjogren's syndrome who have dry eyes and dry mouth may be eligible for this study. Women of childbearing potential will not be considered for participation because of severe birth defects associated with thalidomide. Also, since Sjogren's syndrome affects many fewer men than women, men are excluded from this pilot study because they would be too few in number to assess as a separate group. Candidates will be screened with a medical history, physical examination, blood and urine tests, electrocardiogram, chest X-ray and pregnancy test. Tests will also be done to measure the conduction of electrical impulses along the nerves and to evaluate dryness of the eyes.

Participants will be randomly assigned to take either thalidomide or a placebo (look-alike pill with no active ingredient). The thalidomide dosage will be increased gradually from a starting dose of 50 Mg. up to 300 Mg., depending on side effects. Women of childbearing age who have had a tubal ligation or longstanding infertility will have a pregnancy test every 2 or 4 weeks.

Participants will come to the clinic at the first study visit and again at weeks 4, 8 and 12 for some or all of the following procedures:

  • Patient assessment of dry mouth (rated on a scale from "worst ever" to "best ever"
  • Patient assessment of dry eyes (rated on a scale from "worst ever" to "best ever"
  • Patient health questionnaire and disease assessment rating
  • Saliva collection
  • Rose-Bengal or other dye tests for dryness - examination of the eyes under a bright light following administration of drops containing a dye
  • Schirmer's I test for dryness - placement of a thin rectangular strip of filter paper in the eye following administration of anesthetic drops
  • Blood tests to measure blood cell counts and levels of various immune substances in the blood, and to evaluate liver and kidney function
  • Urine tests to evaluate kidney function
  • Nerve conduction tests - measurement of the speed with which nerves conduct electrical impulses. Two nerves in the arm and one nerve in the leg will be tested.

Participants will also be contacted by telephone every week to report any side effects.

Condition or disease Intervention/treatment Phase
Sjogren's Syndrome Xerostomia Drug: Thalidomide Phase 2

Detailed Description:
Sjogren's syndrome (SS) is a systemic autoimmune disease that predominantly affects women. SS is characterized by lymphocytic infiltration of lacrimal and salivary glands leading to secretory function loss, and the symptoms of dry eyes and dry mouth. After bone marrow transplantation, most patients with chronic graft versus host disease (GVHD) develop symptoms of oral dryness and salivary gland lymphocytic infiltrates indistinguishable from SS. Thalidomide has not been studied as a treatment for Sjogren's syndrome, but pilot studies suggest that it may be beneficial in the treatment of a number of autoimmune diseases including rheumatoid arthritis, systemic lupus erythematosus, and various skin disorders, as well as in the treatment of chronic graft versus host disease. Major adverse effects of thalidomide include teratogenicity, neuropathy and sedation. The study is a 12 week randomized, double-blinded, pilot clinical trial designed to screen for potential efficacy and to evaluate the safety and potential adverse effects of 300 mg thalidomide daily compared with placebo in 28 patients with primary SS (PSS).
