• Sales Fluctuations: Q1 sales of XOLREMDI were lower than Q4 2024 due to inventory resupply timing, indicating potential volatility in revenue from small patient populations.
• Market Competition and Patient Enrollment: Enrollment in the clinical trial is limited to very sick patients, which may restrict the broader applicability of the treatment and could impact market penetration.
• Stock Listing Compliance: A 1-for-30 reverse stock split was implemented to address compliance with NASDAQ listing rules, highlighting financial pressures.

5. Notable Q&A Insights

• Patient Enrollment: The company reported strong demand for enrollment in the 4WARD trial, with physicians eager to include more patients than currently permitted by trial criteria.
• Patient Profile: The enrolled patients are primarily those with moderate to severe CN, aligning with the company's focus on high unmet needs.
