• Shares reached $9.74 on August 19.
• No fresh company-specific announcement, earnings update, regulatory action, or analyst change was identified for August 20. The latest earnings and business update came August 6.
• The broader biotech sector was rising pre-market, so the decline does not appear sector-driven; profit-taking or stock-specific trading may be factors.
