Clinical Trial Summary

The Expanded Access Program will provide access and assess the safety of AMX0035 for the treatment of people living with ALS.

Description:

AMX0035 is a combination therapy designed to reduce neuronal death through blockade of key cellular death pathways originating in the endoplasmic reticulum (ER) and mitochondria. This Expanded Access Program is designed to provide expanded access to AMX0035 for the treatment of people living with ALS and assess safety in diverse populations/stages of ALS over 48 weeks.

• Dependence on invasive mechanical ventilation, defined as being unable to lay supine without it, unable to sleep without it, or continuous daytime use; presence of tracheostomy at Screening;
• No current need for tracheostomy or PAV (defined as more than 22 hours daily of mechanical ventilation for more than one week (7 days) or based on the site investigator's judgment; no need anticipated for the next 12 weeks
• In the judgment of the Investigator, the participant's expected survival is less than 6 months
