Black Diamond Therapeutics Shares Plunge 35.8% Amid Mixed Phase II Results
- Clinical Trial Results: Black Diamond Therapeutics reported a preliminary median progression-free survival (mPFS) of 15.2 months for its phase II trial of silevertinib in NSCLC patients with EGFR non-classical mutations, yet the stock plummeted 35.8% as investors expressed concerns over the early nature of the data and modest patient count.
- Patient Data Analysis: The study enrolled 43 patients treated with a 200 mg dose of silevertinib, with 53% remaining on therapy at the data cutoff, and the longest treatment duration reaching 23.5 months, indicating potential durability of responses, although longer follow-up is needed to clarify the final benefit-risk profile.
- CNS Activity: Silevertinib demonstrated an 86% objective response rate in the central nervous system (CNS), with no new brain metastases reported by the cutoff date, suggesting this profile could be pivotal for the company's development and regulatory strategy, particularly if maintained in larger datasets.
- Safety Management: No new safety signals were observed, but severe treatment-related adverse events decreased to 28% after dose reduction, supporting the decision to adjust the dose to 150 mg; however, the need for dose optimization may have contributed to the negative market reaction.
