Research, Advocacy, Awareness, and Support
The Desmoid Tumor Research Foundation is the world’s leading foundation dedicated to desmoid tumor research, advocacy, awareness, and support.
The priority of the DTRF is to facilitate cutting-edge collaborative research by funding research projects at the world’s top sarcoma centers in basic and translational science and clinical trials. This research seeks to determine what goes wrong in cells to generate these tumors, what medical and surgical options work best, and what existing drugs or potential new drugs could provide effective treatments. In addition to funding research, the DTRF facilitates collaboration between researchers from different institutions to advance desmoid tumor science.

We are just getting started.
With the recent FDA approval of Ogsiveo™ (nirogacestat) as the first-ever approved medical therapy for desmoid tumor patients, our hope continues to thrive! An approval like this propels research and interest in desmoid tumors. The DTRF will continue to aggressively fund research projects and collaborate with industry to accelerate the development of additional therapies toward a cure for each and every desmoid tumor patient.
Our Impact
DTRF-funded research has made significant, record-breaking advancements in our understanding of the disease.
Discoveries made through desmoid tumor research can also potentially have a significant impact on many other more common cancers such as breast, colon, ovarian, and others. We’ve seen exciting progress along the way and the results of this work have never been so clear: The number of clinical trials for desmoid tumor patients that launched in just the last 9 years is greater than the number of trials launched throughout the prior 23 years. In the last 10 years, we’ve seen an increase in the launch of phase II clinical trials and the first phase III trials for desmoid tumor patients.

Every trial
is a possible answer for our community
Every trial
tells us more
Every trial
is hope


After more than a decade of collaboration among advocates, patients, industry, and medical professionals, the U.S. Food and Drug Administration (FDA) has granted approval to SpringWorks Therapeutics for its gamma secretase inhibitor, OGSIVEO™ (nirogacestat), for the treatment of adults with progressing desmoid tumors.
This drug is the first-ever FDA-approved medical therapy for desmoid tumors and represents a beacon of hope for desmoid tumor patients.
Below are examples of some of the ways that the DTRF impacts the research community:
- Annual International Research Workshop for Medical Professionals
- Research Grants
- Collection of published Desmoid Tumor Research
- The DTRF compiles a comprehensive collection of articles and links to published desmoid tumor research, making them accessible to physicians, researchers and patients around the world
- Facilitation of and connecting patients to clinical trials
- Tissue Sample Donations

Patient Testimonials
“
“I was young and had no idea how this diagnosis would drastically change my life. I traveled up and down the east coast seeking answers. Eventually, I stumbled upon the DTRF and, it’s safe to say, they saved me.”
Shannon
Delaware, US
“
“Although we don’t have a one-size-fits-all solution to desmoids, each new choice available to me and my team is a step in the right direction. I’m hopeful that all the exciting research and clinical trials of the past few years will result in more effective treatment options. We don’t have a Desmoid cure… yet. The work done by the Desmoid Tumor Research Foundation is incredibly important for supporting this research, as well as to raising awareness and creating community.”
Eleanor
Oregon, US
“
“The DTRF was not around all those 30+ years ago when I was diagnosed, so it gives me much hope that it is available today so people like me have hope to survive this very destructive tumor.”
Terese
US
“
“The pool of people working on desmoid tumors is growing exponentially and it’s DTRF’s work that is making this happen.”
