About Athina's Ride
Athina's Ride is a cycling event that starts with training rides in the spring and culminates on July 13/14th weekend. You can either complete the ride on your own, with family & friends or join our ride led by Athina Merckx on the Saturday July 13th in Penticton, British Columbia. Come join Athina and support her and other Desmoid patients in the fight to find a cure. This ride will be a casual 30 km route around Naramata bench. If you want more of a challenge raise $1000 and you will receive a free entry into the Okanagan Granfondo on Sunday July 14th and can choose from 4 distances. Ride by yourself, with some friends or along with the Okanagan Granfondo ride. You can ride indoors on a trainer or outdoors (and manually log it or use platforms like Strava to automatically upload your rides). You'll sign up, choose your distance, and start training anytime up until July 14th.
Create an account, log your training distances, and then participate on Ride Day OR in one of four distances at the Okanagan Granfondo. By logging your distances and fundraising, you'll be eligible for great incentives and prizes donated by our great supporters!
The Desmoid Tumor Foundation, which the ride supports, is an organization dedicated to funding research for treatments and cures, providing patient support, and ensuring that those affected by desmoid tumors have access to necessary resources. By contributing to the foundation, Athina's Ride helps to foster hope and to drive forward the science that may one day lead to a world free of the challenges imposed by desmoid tumors.
What is a Desmoid Tumour or Aggressive Fibromatosis?
Desmoid tumours, also called aggressive fibromatosis or desmoid-type fibromatosis, are rare and often debilitating and disfiguring soft-tissue tumours. They are characterized by a growth pattern that can invade surrounding healthy tissues, including joints, muscle and viscera. While they can arise in any part of the body, the most common sites are the upper extremities (arm, forearm, and hand), lower extremities (hip, thigh, leg, and foot), abdominal wall, thoracic areas, and the head and neck.
The severity of a desmoid tumour can vary based on the location of the tumour and the aggressiveness of its growth pattern. Desmoid tumours can cause significant morbidities, including severe pain, internal bleeding, incapacitating loss of range of motion, and, in rare cases, death.
While desmoid tumours can occur in people between 15 and 60 years of age, they are most commonly diagnosed in young adults between 30-40 years of age. Women are also 2 to 3 times more likely to develop them than men.

The Desmoid Tumour Foundation of Canada (DFC) is the official Canadian charity for desmoid research.
Since our first fundraiser in May 2017, the DFC has donated $295,000 towards Desmoid research. We are dedicated to funding research to help find better treatments and ultimately a cure for this devastating disease.
Unlike more well known diseases, rare conditions like Desmoids do not receive the same amount of funding for research. Funding cutting-edge research is the only way to develop new and effective therapies. Thanks to the research underway through the US foundation DTRF and the money we have raised in Canada, we are now seeing an exciting number of new drugs and modalities to treat this condition. But there is a lot more work to be done.

DFC Funding: $19,200 CDN
Lay Abstract: Desmoid tumors (DT) are aggressive tumors predominantly affecting young people. They
can potentially cause significant pain, decreased limb mobility and invalidity. In certain individuals, DTs
can even be life threatening. Although some tumors may spontaneously shrink or remain stable without
any treatment, patients with growing tumors will require either surgery or chemotherapy. Over the last
decades, a number of drugs including hormonal blockers like tamoxifen, intravenous chemotherapy like
weekly methotrexate and vinblastine and doxorubicin and targeted therapy like imatinib have shown
various degrees of success in treating DTs. Recently, two new targeted drugs, sorafenib and pazopanib,
were approved to treat DTs. In clinical trials, DTs treated with either drug shown significant tumor
shrinkage and control over time. Since their approval and routine use in practice, there remains many
unknowns. Duration of treatment is still ill defined. Outcomes of patients who failed or stopped
sorafenib or pazopanib are unknown. Predicting which patients may respond to these novel drugs is still
a challenge. The main objective of this multicenter Canadian retrospective study is to collect real world
data to better guide physicians in managing these rare tumors.

Proposal Title: Targeting hexosamine biosynthesis pathway for the treatment of desmoid tumors
Total Budget/Length: $130,000 over 2 years
DFC Funding: $41,600 CDN/year for 2 years (total $83,200)
Lay Abstract: Cancer cells rewire metabolic pathways and energy production to support the enhanced
proliferation, invasion and resistance to treatment. We recently found a remarkable enrichment of
genes involved in hexosamine biosynthesis pathway (one of the glucose metabolism pathways) in a
subset of leiomyosarcoma (LMS). We demonstrated that expression of GFPT2, the key enzyme of the
hexosamine biosynthesis pathway, is associated with poor clinical outcome in LMS. Following the study
on this pathway in LMS, we performed a large-scale immunohistochemistry screening of more than 30
different types of soft tissue tumors and we discovered nearly universal expression of GFPT2 in desmoid
type fibromatosis (DTF). Our high-throughput transcriptomic analysis of DTF and 9 other types of fibrotic
lesions identified significant enrichment of multiple genes implicated in hexosamine biosynthesis
pathway in DTF compared to the other types of fibrotic lesions. We also found a candidate effector of
the activation of this pathway in DTF, which may have a pro-oncogenic role and may be associated with
resistance to treatment.
Targeting hexosamine biosynthesis pathway was demonstrated to provide therapeutic benefit in a
number of preclinical models of cancer. Thus, our preliminary findings provide a rationale to explore the
potential of therapeutic targeting of the hexosamine biosynthesis pathway in DTF. The modulation of
glucose metabolism through hexosamine biosynthesis pathway is a promising direction of research and
our proposal offers the first functional exploration of the role of this pathway in DTF. Successful
completion of this study will hopefully lead to novel therapeutic options for patients with DTF.

Proposal Title: Investigating EXH2 as a druggable mediator of immune cell exclusion in desmoid tumours
Total Budget/Length: $65,000 (year 2 of 2)
DFC Funding: $41,600 CDN
Below is a lay-friendly summary of the findings and impact (or potential impact) in desmoid research
and/or patient care. At this moment we have set up several experiments to test our central hypothesis
that a molecular therapy that we found previously to mediate desmoid tumor shrinkage in a genetic frog
model, is doing this by the activation of an anti-tumor immune response. The readouts for these
experiments will become available in the next coming months. If the working hypothesis is confirmed,
this opens roads for treatment of desmoid tumor patients via immune checkpoint inhibition therapy.

Sub-study: Desmoid tumor and pregnancy: effect of pregnancy on disease control and effect of
diagnosis on pregnancy history. An international multicenter retrospective observational study:
Investigating EXH2 as a druggable mediator of immune cell exclusion in desmoid tumours
Total Budget/Length: $15,000 year 1 of 1
DFC Funding: $15,000 CDN
A significant proportion of female patients with a diagnosis of Desmoid Tumours (DT) have a recent
pregnancy history and on the contrary, the diagnosis of DT is often made during gestation or shortly
thereafter. Although some evidences suggest that Desmoid is modulated by hormonal signaling (i.e.
estrogens), the role of specific signaling pathways is not well understood.
Understanding the behavior of desmoids during or after pregnancy is crucial to define the safest
management of the tumor itself and of the pregnancy. Defining the impact of DT on any decision to
interrupt or avoid pregnancy and on obstetrics risk is pivotal to early define potentially worrisome
conditions. Moreover, analyzing the impact of DT on decisions regarding the pregnancy (and in turn
fertility), we will be able to implement new tools assisting and counselling women with Desmoids.
There is a growing interest in defining potential risk of recurrence or progression during or after
pregnancy and in identifying potential obstetrical risks and infertility rate of desmoid patients.
Defining the impact of pregnancy on diagnosis, progression and recurrence of DT will help defining the
best therapeutical approach to fertile patients. If we are able to define potential risk factors for tumor
progression, we could adequate the follow-up regimen and the therapeutic sequence. Understanding
the effect of Desmoids on pregnancy will also better define the risk of pregnancy/delivery and the
eventual desire to avoid pregnancy. Finally, defining the potentially detrimental psychological effect of
DT diagnosis on pregnancy planning would help providing our patients with the adequate tools for
counseling.
