Our diagnostic and prognostic tests provide personalized, clinically actionable information to help healthcare providers and patients make more informed decisions about their treatment plans. Our test for invasive cutaneous melanoma, DecisionDx®-Melanoma, is a proprietary gene expression profile, or GEP, test that more accurately predicts a patient’s risk of metastasis or recurrence as well as sentinel lymph node positivity. DecisionDx®-SCC is our GEP test that predicts the risk of metastasis for patients with cutaneous squamous cell carcinoma, who have one or more risk factors. DecisionDx®-UM, the standard of care in uveal melanoma staging, is our GEP test that predicts the risk of metastasis for patients with uveal melanoma, a rare eye cancer. Our comprehensive diagnostic offering — myPath® Melanoma and DecisionDx® DiffDx™-Melanoma — provides a highly accurate, objective result to aid dermatopathologists and dermatologists in characterizing suspicious pigmented lesions.

Castle has active research and development programs for tests in other dermatologic diseases with unmet clinical need, including its test in development to predict systemic therapy response in patients with moderate to severe psoriasis, atopic dermatitis and related conditions. If successful, our pipeline tests will add approximately $3.6 billion to our estimated U.S. total addressable market, bringing the total to approximately $5.5 billion.
