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. The grants were made under the Company's 2022 Inducement Plan, complying with Nasdaq Listing Rule 5635(c)(4). The RSUs have a four-year vesting schedule, with 25% vesting after the first year and the remaining balance vesting in three equal annual installments, contingent on continued employment.
Castle Biosciences (CSTL) announced the publication of an independent meta-analysis in Cancers evaluating their DecisionDx-Melanoma test for predicting melanoma patient outcomes. The analysis, reviewing 13 peer-reviewed studies, confirms the test's effectiveness in risk stratification for cutaneous melanoma (CM) patients.
The study revealed five-year melanoma-specific survival rates of 99.8% for lowest risk (Class 1A), 97.6% for increased risk (Class 1B/2A), and 83.4% for highest risk (Class 2B) patients. The test demonstrated consistent ability to stratify patients into risk groups with significantly different outcomes, supporting its use alongside current staging systems for enhanced patient care management.

Castle Biosciences, a precision medicine company, announced a milestone for its TissueCypher Barrett’s Esophagus test, surpassing 25,000 test reports delivered since acquiring the test in late 2021. TissueCypher predicts the risk of progression from Barrett’s esophagus (BE) to esophageal cancer. BE is the only known precursor to esophageal adenocarcinoma, a rapidly increasing cancer in the U.S. with a five-year survival rate of 22%. TissueCypher, supported by 14 peer-reviewed studies, outperforms traditional pathology diagnoses, providing personalized risk scores and actionable insights. This test can help clinicians make informed decisions, potentially preventing esophageal cancer through tailored surveillance and intervention strategies.
Castle Biosciences presented new data from their DECIDE study showing that their DecisionDx-Melanoma test reduced unnecessary sentinel lymph node biopsy (SLNB) procedures by 25%. The study, presented at Dermato-Onco2024, included 471 patients with T1-T2a melanoma tumors. Among patients who underwent SLNB, none with low-risk DecisionDx-Melanoma results (predicted risk <5%) had positive nodes, while 9.8% of those with predicted risk ≥5% showed positive results. The test integrates tumor biology with clinicopathologic factors to predict SLN positivity risk, helping physicians and patients make informed decisions about SLNB procedures.

Castle Biosciences (CSTL) presented new data at ACG 2024 showing their TissueCypher® test can significantly reduce healthcare costs and improve quality of life for Barrett's esophagus (BE) patients. Using a simulation model of 10,000 patients, the study demonstrated a $17M decrease in BE management costs when patients identified by TissueCypher as high-risk received endoscopic eradication therapy. The test reduced esophageal cancer progression by 58.4% and EAC-related death by 59.6%. The abstract received a Presidential Poster Award, an honor given to only 5-7% of submissions for outstanding research.
