Funding Desmoid Tumor Research and Providing Support The Desmoid Tumor Research Foundation Experience CTOS, Berlin, October

What We Do and Why It Matters DTRF is dedicated to: Funding research for a cure for desmoid tumors Providing informational support to patients.

Patient Support:

Annual DTRF Patient Meeting Presentations from desmoid tumor researchers and physicians; patients meet one another Has grown to 275 attendees in 2014 Participants from 26 states and 7 countries including Spain, Italy, Germany, Ecuador, Singapore, Canada, Netherlands

Running for Answers 5K & Kids’ Fun Run We combine our Patient Meeting with our largest fundraiser – Running for Answers 5K with 800 participants!

Funding Research Brigham and Women's Hospital Duke University Fondazione IRCCS Istituto Nazionale dei Tumori Maine Medical Center MD Anderson Cancer Center Memorial Sloane Kettering Cancer Center Stanford University The Hospital for Sick Children The Ohio State University University of Pennsylvania University of Chicago Huntsman Cancer Center Vanderbilt University Medical Center

Next Generation Sequencing Approach to Desmoid Tumors Matt van de Rijn, MD-PhD Joanna Przybyl, PhD Justin Cates, MD- PhD Thomas Stricker, MD- PhD

Two Complimentary Approaches Using shared samples sets Vanderbilt and Stanford groups are looking at: 1-exome sequencing » mutations, indels, translocations 2-gene expression profiling » mRNA, lncRNA expression levels

We asked if mutations in the gene for b-catenin production correlated with desmoid recurrence The Ohio State University Comprehensive Cancer Center

Desmoid Recurrence Impact on clinical decision-making It is more prevalent with 45F mutation in the gene regulating b-catenin production

Collaboration for a Cure: Identifying new therapeutic targets for desmoid tumors

Screen compound libraries for agents that target desmoid cell culture viability but not normal fibroblast viability Test positive hits in additional cell cultures Test agents that have potential for rapid translation to patient care in mice Re-screen agents that work in mice for additive effects with other agents Test a multi-drug regimen in cells and then in mice “Collaboration for a Cure”

A Multicenter, Phase III, Double Blind, Randomized, Placebo-Controlled Trial of Sorafenib in Desmoid Tumors Study Chair/PI: Mrinal Gounder (MSKCC) Co-PI: Gary Schwartz (Columbia) and Robert Maki (Mt. Sinai) ALLIANCE chair: Monica Bertagnolli (Harvard) ALLIANCE Trial: A large network of hospitals. This study is being conducted in hospitals throughout the U.S. Opened in March Updated list of centers can be found at

This is the first Phase III trial in desmoid tumors. Largest trial and will be open in 100+ hospitals throughout the U.S. Can Nexavar delay/avoid surgeries, radiation or chemotherapies? If this is successful, it paves the way for evaluating new drugs in this and other rare tumors. Impact

First International DTRF Desmoid Tumor Research Workshop

Research Workshop – Next Steps Developing single cell derived clonal lines for desmoid tumors that can be available to researchers world wide - perhaps through an RFA process; The development of a registry of research materials amiable for sharing by the community (e.g. a registry of genetically modified mice that are amiable); Consideration of the development of a multicenter registry and tissue bank; Development of clinical measures for outcome of drugs to be tested through the FDA (e.g. volumetric measures); and The development of an open access process for the rapid exchange of research ideas.
