Study Summary

T cells, a type of white blood cell called a lymphocyte, play an important role in the immune system. One subtype, the regulatory T cell (Treg) helps to regulate the immune system and may provide protection against the development of autoimmune disease. The hope is that these naturally occurring Treg cells can be utilized for the treatment of autoimmune disease and potentially replace the use of chronic immunosuppressive therapies that are associated with multiple side effects. There has been a small study showing safe administration of Tregs with decreased disease activity in patients with insulin-dependent diabetes. Tregs are being studied in lupus, cancer and organ transplantation. This phase I trial will be conducted as an open-label, dose-escalation, multicenter trial in adult participants with active pemphigus.The purpose of this study is to test the safety and effect of Treg therapy in participants who have skin (cutaneous) involvement due to pemphigus.

Primary Outcome

Number of significant adverse events, defined as any related National Cancer Institute (NCI) Common Toxicity Criteria for Adverse Events (CTCAE) version 4.03 Grade 3 or higher adverse event or any related serious adverse event (SAE). Related is defined as being possibly related or related to the ex vivo expanded autologous PolyTregs, as determined by the safety review committee. An SAE is any untoward medical occurrence that, at any dose\* results in death, is life-threatening, requires hospita
