Clinical Trials for Canine Hemangiosarcoma
Hemangiosarcoma is an aggressive cancer of the blood vessel walls, most commonly affecting the spleen, heart, and skin in dogs. It is particularly common in Golden Retrievers, German Shepherds, and Labrador Retrievers. Despite its severity, several university research programs are actively studying new treatments including targeted therapies and immunotherapy through fully or partially funded clinical trials.

Understanding Hemangiosarcoma in Pets
Hemangiosarcoma arises from blood vessel cells and most often affects the spleen, heart, or skin in dogs. Internal forms often go undetected until sudden illness occurs.
Who it tends to affect
- Typical size: More commonly diagnosed in larger and medium-sized breeds, though any size dog can be affected
- Typical age: Most often seen in older dogs, typically 8 years and older
Breeds it's seen in more often
Golden Retrievers, German Shepherds, Labrador Retrievers.
This is which breeds tend to develop hemangiosarcoma — not a list of who can join a trial. See eligibility below.
Can my pet join — does breed matter?
Most trials screen by disease location (splenic, cardiac, subcutaneous), prior treatment, and body weight rather than breed. Dogs of any breed meeting the study's health criteria are typically eligible.
Most trials are open to all breeds and set requirements by size, weight, age, and diagnosis instead. Our matching service checks your pet's specific details against each study's actual requirements.

What Hemangiosarcoma Trials Typically Cost
Many trials cover part or all of treatment costs. Of the 16 trials we're currently tracking for hemangiosarcoma:
The trials themselves are run by research institutions — we don't charge for them. Funding status changes as studies open and close, so we confirm current coverage when we match your pet.
What Hemangiosarcoma Research Is Focused On
Current studies for hemangiosarcoma are exploring approaches like:
- •Immunotherapy and immune-stimulating approaches
- •Anti-angiogenic therapy targeting blood vessel growth
- •Combination chemotherapy protocols
- •Quality-of-life research during treatment
How it works
Tell us about your pet
Share the diagnosis, your pet's age and size, and your location. It takes a few minutes — no account needed.
We research current trials
We check open studies against your pet's actual eligibility — diagnosis, stage, location, and prior treatment. Most matches come back in 2–3 days.
You get your matches
A personalized list of trials your pet may qualify for, with locations, funding status, and exactly how to enroll.
The trials themselves are free and run by research institutions. Our fee covers the research and eligibility matching — and if we don't find any matches for your pet, you don't pay.
