• FDA requests additional animal exposure data for NUZ-001
• No safety concerns identified from previous clinical studies
• Company confident in addressing FDA's request to advance NUZ-001 clinical program

Neurizon Therapeutics Limited, a clinical-stage biotech company dedicated to advancing treatments for neurodegenerative diseases, received guidance from the U.S. Food and Drug Administration (FDA) regarding the company's Investigational New Drug (IND) application for its lead drug candidate, NUZ-001. The FDA has requested additional animal exposure data to assess the adequacy of systemic exposure to NUZ-001 in previous studies. Neurizon has commenced initiatives to generate the additional data and remains confident that this information will assist in reinforcing and better defining the safety margins for NUZ-001's clinical development program. Importantly, the FDA did not specify any safety concerns arising from the previously undertaken clinical studies utilizing NUZ-001. The company's management, scientific, and regulatory teams are working to expeditiously address the FDA's request, leveraging their established expertise and strong industry partnerships. The impact of the FDA's request on the timeline of Neurizon's planned ALS clinical trial is currently being assessed, and the company will provide further updates to shareholders as developments materialize.

Neurizon remains committed to advancing NUZ-001 as an effective potential treatment for ALS and other neurodegenerative diseases. The company is confident in its ability to address the FDA's request and continue the clinical development of NUZ-001.
