The mission of the ITN is to advance the clinical application of immune tolerance by performing high quality clinical trials of emerging therapeutics based upon testable mechanistic hypotheses. The ITN is structured in order to interrogate different diseases across the immunologic spectrum, with integration of innovative clinical studies and cutting edge immunology laboratory analysis. The ITN approach?clinical assessment of novel tolerance therapeutics, while we simultaneously evaluate the cellular, genetic, and immunologic mechanisms of disease and how they are altered in response to therapy?creates a framework for advancing cross-disease and cross-discipline knowledge, all designed to accelerate therapeutic options for major diseases. In this renewal application, we describe the scientific and operational framework that will enable the ITN to successfully enhance the development of tolerance therapies in transplantation, autoimmunity, and allergy. We outline a process to evolve our current strategies into the next generation of planned trials, as well as how we plan to operate a nimble, future-focused organization, poised to lead and adopt innovations that are currently unknown. We propose a collaborative structure involving hundreds of investigators, advisors, and clinical sites working in tandem with a core group of ITN staff, operating a program that is both scientifically and financially efficient. Several new innovations recently adopted by the ITN will encourage widespread involvement from academic investigators, including expanded resource sharing and data sharing operations. With lead institutional commitment from the Benaroya Research Institute and the University of California San Francisco, and participation of more than 20 other major institutions represented in leadership and major advisory roles, the ITN strives to continue to successfully pioneer high impact clinical trials and mechanistic studies in areas of unmet medical need.

Public Health Relevance

The proposed ITN UM1 funding addresses major unmet health needs. In the United States, autoimmune diseases affect >5% of the population, and allergic diseases affect another ~15%. Transplantation is a life- saving intervention for organ failure, but risky and burdensome. In each area, pre-clinical studies show that immune tolerance should be an achievable therapeutic prospect, and progress towards that goal is evident in recent clinical trials. Successful tolerance offers long-term freedom from immunosuppressive therapy, radically improving quality of life, disease burden, and health care costs. 1 Abstract
