Accelerate Discovery
Research & Drug Development Tools
As part of our mission to advance research through collaboration, the EHE Foundation provides references to preclinical and clinical resources that have been developed to advance EHE science. We promote a community that fosters the sharing of information, data, and resources to minimize the likelihood of redundant efforts while accelerating the search for a cure.
Preclinical Research Tools & Resources
EHE Biobank: Annotated Biospecimens
Molecularly confirmed, annotated tumor tissue, blood, plasma, and serosal specimens are stored and made available for ethical research through the EHE Biobank.
EHE Patient-Derived Xenograft (PDX) Model & Cell Lines
Human-derived EHE PDX and subsequent adherent and spheroid cell lines have been generated by the Instituto Nazionale Tumori in Milan, Italy.
EHE Extended Cell Cultures
EHE extended cell cultures developed in partnership with the Tanas Lab at the University of Iowa.
Genetically Engineered Mouse Model (GEMM) & Cell Lines
An engineered conditional EHE mouse model that closely mirrors EHE in humans, including its clinical, histological, immunohistochemical, and genetic phenotypes. Developed in the Rubin Lab at Cleveland Clinic, this fully credentialed preclinical model of EHE is driven by conditional expression of WWTR1-CAMTA1 from the endogenous WWTR1 locus.
EHE Publication Library
Explore case reports, retrospective studies, relevant reviews, and other publications about EHE clinical care, research, and relevant topics.

Clinical Research Resources & Data
EHE Global Patient Registry and Natural History Study
A rich data resource to improve the understanding of EHE, including demographics, presentation of disease and disease-related symptoms, and treatment utilization and outcomes.
Completed Clinical Trials
- A Single-Arm Phase 2 Trial of Trametinib in Patients with Locally Advanced or Metastatic Epithelioid Hemangioendothelioma
- A Phase 2 Study of Eribulin in Patients with Metastatic Angiosarcoma and Epithelioid Hemangioendothelioma
- Sorafenib in patients with progressive epithelioid hemangioendothelioma: a phase 2 study by the French Sarcoma Group (GSF/GETO)
