Phase I Study of the Humanized Mik-Beta-1 Monoclonal Antibody Directed Toward IL-2/IL-15R Beta (CD122) That Blocks IL-15 Action in Patients With Refractory Celiac Disease


Rochester, Minn.

Trial status:
Open for Enrollment
Why is this study being done?

The purpose of this study is to assess the administration of a monoclonal antibody (HU-Mik-β1) for the treatment of Refractory Celiac Disease. Currently there are no established or effective treatments for RCD beyond supportive measures and immune suppressive-like steroids. The drug targets the effects of a signal (IL-15) in the body that is believed to cause much of the damage in the intestine from refractory celiac disease. It is hoped that this drug will lessen the damage in your intestine and/or lessen the severity of the RCD. HU-Mik-β1 is experimental and isn't approved by the U.S. Food and Drug Administration (FDA). However, the FDA has allowed the use of this drug in this research study.
