<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The updated NCCN Clinical Practice Guidelines in Oncology for SCLC relating to LEMS now include symptom specificity&#151;characterized by proximal muscle
weakness and autonomic dysfunction. Under &#147;Signs and Symptoms of Small Cell Lung Cancer&#148; <FONT STYLE="white-space:nowrap">(SCL-A</FONT> 2 of 2), the guidelines recommend diagnosis through a neurological evaluation, ideally in consultation
with a neurologist, which may include testing for <FONT STYLE="white-space:nowrap">PQ-</FONT> and <FONT STYLE="white-space:nowrap">N-type</FONT> VGCC antibodies. Additionally, under &#147;Principles of Supportive Care&#148; <FONT

<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Approximately 50&nbsp;percent of LEMS cases are associated with an underlying malignancy, most commonly SCLC. Literature suggests that LEMS is observed in
3&nbsp;percent of SCLC patients. Based on an internal healthcare database analysis of SCLC claims, potentially 90&nbsp;percent of LEMS patients with SCLC went undiagnosed. These undiagnosed LEMS patients may suffer from LEMS symptoms while
undergoing treatment for SCLC. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">&#147;Early diagnosis of LEMS in SCLC is critical, as it may enable patients to have better outcomes if their LEMS
symptoms are effectively treated while fighting SCLC. Accurate identification through VGCC antibody testing and comprehensive neurological evaluation is essential,&#148; said William Andrews, MD, FACP, Chief Medical Officer, Catalyst. &#147;The NCCN
Guidelines are a trusted standard for guiding treatment decisions, and we believe this update will drive greater awareness. Ultimately, it will help patients, caregivers, and healthcare providers make more informed choices when addressing this
