<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">&#147;We are pleased that Health Canada has accepted the New Drug Submission for AGAMREE with a Priority Review, recognizing its potential to address a
significant unmet need for patients with Duchenne muscular dystrophy in Canada,&#148; stated Richard J. Daly, President and CEO of Catalyst. &#147;In collaboration with our Canadian <FONT STYLE="white-space:nowrap">sub-licensee,</FONT> Kye, we

dystrophy (DMD) is a genetic disorder characterized by progressive muscle degeneration and weakness. It primarily affects males, with symptoms typically appearing in early childhood, around ages three to five. DMD is caused by mutations in the gene
that encodes dystrophin, a protein that plays a crucial role in maintaining the structure and function of muscle fibers. Without dystrophin, muscle cells become fragile and easily damaged, leading to progressive muscle degeneration. Symptoms of DMD
usually begin with difficulty in walking, frequent falls, and muscle weakness, particularly in the legs and pelvis. As the disease progresses, individuals may experience difficulty standing, climbing stairs, and eventually, complete loss of
mobility. Other complications can include respiratory and cardiac issues due to muscle weakness. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>About AGAMREE<SUP

glucocorticoid and mineralocorticoid receptors and modifying further downstream activity. As such, it is considered a novel corticosteroid designed to achieve dissociative properties while maintaining efficacy that has the potential to demonstrate
comparable efficacy to steroids, with the potential for a better-tolerated side effect profile. This mechanism of action may allow AGAMREE to emerge as an effective alternative to the current standard of care corticosteroids in children,
adolescents, and adult patients with DMD. In the pivotal </P>
