About Vitiligo and AMG 714

• Vitiligo is an autoimmune disorder in which some of your body’s immune cells, called T cells, attack melanocytes (the pigment producing cells in the skin). This leads to patches of skin depigmentation (loss of normal skin color). Scientists believe that specific T cells, called tissue resident memory T cells (Trm), are involved in the attack on melanocytes. Trm cells depend on the chemical signal IL-15. Therefore, scientists believe that interrupting the IL-15 signal might lead to a decrease in Trm cells, which might make vitiligo better.
• AMG 714 is an experimental drug that interferes with IL-15 and may stop the immune system’s attack on melanocytes and allow the melanocytes to produce normal color in the skin (repigmentation).

What do participants need to know?

• Eligible participants will be randomly assigned to one of two groups: One group will receive the study drug, AMG 714; the other group will receive an inactive substance called a placebo. 
• This study is double-blinded, which means that during the study, neither you nor your study doctor will know who is receiving AMG 714 or placebo.
• The treatment period is 12 weeks long, consisting of 6 clinic visits with subcutaneous doses every 2 weeks
• The follow-up period is approximately 36 weeks, during which there are 5 clinic visits
• During the follow-up period, participants may require Narrowband Ultraviolet B light (nbUVB) phototherapy treatment for approximately 24 weeks which will be provided at no cost
• You will have a 2 out of 3 chance of receiving active study drug, and a 1 out of 3 chance of receiving placebo

You may be eligible to participate in the REVEAL study if you:

• Are between the ages of 18 and 75
• Have been diagnosed with vitiligo by a dermatologist
• Have a noticeable amount of vitiligo both on your face and on your body
• Are willing to stop other treatments for vitiligo
