Castle Announces Early Exploratory Study Data for Potential Development of a Complementary Test to Accompany DecisionDx®-UM That Could Aid in the Early Detection of Uveal Melanomas

Renowned eye cancer expert and study investigator, Amy Schefler, M.D., will share early data from a study to explore the potential for developing a complementary test that would be tailored for individuals presenting with small, suspicious lesions of uncertain malignant potential
Data will be presented at the 2023 American Academy of Ophthalmology (AAO) Annual Meeting in
“We are excited about the possibility of developing a new minimally invasive test that would complement our current test offerings for patients with uveal melanoma, including DecisionDx®-UM, and reinforce our dedication to this important patient population,” said Robert Cook, Ph.D., senior vice president of research and development at Castle Biosciences. “This test would potentially identify aggressive uveal melanomas when they are small and more likely to be cured by prompt therapeutic interventions.”
Bill Harbour, M.D., ophthalmologist, ocular oncologist, and professor and chair of the department of ophthalmology at UT Southwestern Medical Center, is also collaborating with Castle on the study. Harbour is a leading innovator in the treatment and study of uveal melanoma and the original developer of the DecisionDx-UM test, which he licensed to Castle in 2009.
“For small ocular tumors suspected of being an early melanoma, the current standard of care is a ‘watch and wait’ approach using certain clinical characteristics to estimate the risk of malignancy,” said Harbour. “Unfortunately, this approach is highly subjective and can lead to both under- and over-treatment of patients. Through this study, we are looking for aqueous biomarkers that can easily and safely be obtained from the front part of the eye during a quick office procedure that would signal a small tumor may be malignant, which could prompt a definitive tumor biopsy and appropriate intervention.”
Study data is being shared by Amy Schefler, M.D., board-certified ocular oncologist and vitreoretinal surgeon at Retina Consultants of

About the Ongoing Exploratory Study
Each year, up to 12,000 individuals present with a small suspicious uveal melanocytic lesion of uncertain malignant potential in one of their eyes; however, only about 2,000 of these patients will be diagnosed with uveal melanoma and undergo definitive tumor treatment and molecular prognostic biopsy. The current clinical standard of care to determine which patients to treat involves a “watch and wait” approach that consists of monitoring lesions for growth or appearance of high-risk features that would indicate transformation into a malignant melanoma. Castle’s ongoing exploratory study is investigating the potential for developing a test that would complement DecisionDx-UM and provide a minimally invasive solution to identify lesions with aggressive biology earlier, enabling more timely treatment with the goal of improving uveal melanoma patient outcomes.
About DecisionDx®-UM
DecisionDx-UM is Castle Biosciences’ 15-gene expression profile (GEP) test that uses an individual patient’s tumor biology to predict individual risk of metastasis in patients with uveal melanoma. DecisionDx-UM is the standard of care in the management of newly diagnosed uveal melanoma in the majority of ocular oncology practices in
It is estimated that nearly 8 in 10 patients diagnosed with uveal melanoma in
