Castle Biosciences (CSTL) has received assay approval from the New York State Department of Health for its TissueCypher Barrett's Esophagus test. This approval marks the completion of New York state approval for all of Castle's tests across its dermatology, gastroenterology and ophthalmology portfolios, as well as its clinical laboratories in Phoenix and Pittsburgh.
TissueCypher is the first AI-driven precision medicine test designed to predict progression risk from Barrett's esophagus (BE) to esophageal cancer. The test analyzes cancer-associated biomarkers and spatial biology features to identify molecular signatures of BE progression before visible tissue changes occur. This tool helps clinicians risk-stratify the estimated 5% of U.S. adults with BE, enabling risk-aligned surveillance or earlier interventions to prevent cancer development.
Castle Biosciences (CSTL) provided an update on its pipeline test for moderate-to-severe atopic dermatitis (AD) patients seeking systemic treatment. Preliminary data shows the test may identify patients likely to achieve a super response (90% or greater reduction in EASI score) to targeted therapies within three months.
The company has enrolled over 1,100 patients across 39 clinical study sites for its development and validation study. With an estimated 6 million U.S. patients diagnosed with moderate-to-severe AD annually, and approximately 760,000 seeking systemic treatment, the test aims to improve the current 'trial-and-error' approach, where 25% of patients discontinue initial therapy and 50% show persistent disease burden.
Assuming successful validation, Castle expects to launch the test by the end of 2025.
Castle Biosciences (CSTL) announced that its Board of Directors' Compensation Committee has granted restricted stock units (RSUs) to 135 employees, covering 173,542 shares of common stock.
