Safety Study of XT-150 in Participants With ALS

The main questions this study is aiming to answer are: * What adverse events are reported during this study? An adverse event is any "side effect" that participants have during a study. Adverse events may or may not be caused by XT-150. The study doctors will check participants' ALS and general health throughout the trial. * Does XT-150 have any effects on participants' physical examination findings, vital signs, or laboratory values? In addition to evaluating the safety of XT-150, this study will also collect samples to provide information on the following: * The levels of XT-150 in your body * The effect of XT-150 on cytokines including interleukin (IL)-10 * The effect of XT-150 on relevant ALS biomarkers such as Neurofilament Light (NfL) In addition, ALS functional score, breathing capacity and strength will be collected over the course of the study.
