Gold nanoparticles offered to ALS patients in expanded access program
NCT ID NCT05281484
First seen Jun 27, 2026 · Last updated Aug 25, 2026 · Updated 2 times
Summary
This program provides CNM-Au8, a suspension of gold nanocrystals, to up to 300 people with ALS. The main goal is to give access to the drug and monitor safety, not to test if it works. Participants must have a confirmed ALS diagnosis and be at least 18 years old.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- CNM-Au8 (nanocrystalline gold suspension)
- What this could lead to
- If successful, this could provide a treatment option for ALS patients, potentially slowing disease progression.
- What could go wrong
- This is an expanded access program, not a formal trial, so it won't prove effectiveness. Safety is the main focus, and benefits are uncertain.

For Protocol CNMAu8.EAP01 The participants must meet the following inclusion criteria: 1. Able to understand and give written informed consent. 2. Male or female participants aged 18 years or greater (inclusive) at the time of ALS diagnosis. 3. Participants whose conditions are defined as "definite ALS" or "probable ALS" or "possible ALS" diagnostic criteria by the revised El Escorial Criteria as determined by a neurologist specializing in ALS (e.g., the Principal Investigator or sub-investigator at the site). 4. Participant is able to daily consume 60 mL of the investigational drug suspension without substantial dysphagia, OR can intake the drug through a gastrostomy tube. 5. In the judgement of the Investigator, the participant's expected survival is greater than six-months 6. Participants who have established care with a neurologist at the specialized ALS center involved in the study and will maintain this clinical care throughout the duration of the EAP. 7. Participant must have completed standard clinical safety labs within the prior 90 days from the Baseline visit including a chemistry panel (e.g., CMP) and a hematology panel (e.g., CBC). OR Prior participation in the HEALEY Platform ALS trial (Regimen C) Open Label Extension (NCT04414345) will be considered an automatic inclusion. Participants will be excluded from the expanded access protocol if they meet any of the following criteria: 1. Participant is eligible for a clinical study with CNM-Au8 for the treatment of ALS. 2. Participant with a history of any clinically significant or unstable medical condition based on the Investigator's judgment that may interfere with assessment of the study objectives. 3. Based on the investigator's judgment, participants who may have difficulty complying with the protocol and/or any study procedures. 4. Within the prior 90 days the participant has had clinically significant abnormalities in hematology, blood chemistry, ECG, or physical examination not resolved by the Baseline visit which according to Investigator can interfere with EAP participation. 5. Participant is currently involved in another placebo-controlled clinical trial (note: concomitant therapy with other investigational products is permitted with certain restrictions. 6. Females who are pregnant or nursing or who plan to get pregnant during the course of this EAP or within 6 months of the end of the EAP. 7. Females of child-bearing potential, or men, who are unwilling or unable to use accepted methods of birth control. 8. History of gold allergy. OR These exclusion criteria will not be applied if the participant was previously enrolled in the HEALEY Platform ALS trial (Regimen C) Open Label Extension (NCT04414345). For Protocol CNMAu8.EAP02 Inclusion Criteria: 1. Able to understand and give written informed consent. 2. Male or female participants aged 18 years or greater (inclusive) at the time of ALS diagnosis. 3. Participants with a confirmed diagnosis of ALS per Gold Coast criteria as determined by a neurologist specializing in ALS (e.g., the site principal investigator or sub-investigator for this study). 4. Participant is able to daily consume up to 240 mL of the investigational drug suspension without substantial dysphagia, OR can intake the investigational product through a gastrostomy tube. 5. Participant must have completed standard clinical safety labs within the prior 90 days from the Baseline visit including a chemistry panel (e.g., CMP) and a hematology panel (e.g., CBC). 6. In the judgement of the Investigator the participant's expected survival is greater than six-months. 7. Participants who have established care with a neurologist at the specialized ALS center involved in the study and will maintain this clinical care throughout the duration of the EAP within the United States. OR Prior participation in the HEALEY Platform ALS trial (Regimen C) Open Label Extension (NCT04414345) will be considered an automatic inclusion. Exclusion Criteria: 1. Participant is eligible for participation in: (i) the HEALEY ALS Platform trial (NCT04297683), or (ii) any active study investigating CNM-Au8 for the treatment of ALS. 2. Participant has a history of any clinically significant or unstable medical condition (other than ALS) that may interfere with assessment of safety or compromise the study objectives. 3. Based on the investigator's judgment, participants who may have difficulty complying with the protocol and/or any study procedures. 4. Within the prior 90-days the participant has had clinically significant findings on standard hepatic, hematologic, or renal safety assays. 5. Participant is currently involved in another placebo-controlled clinical trial (note: concomitant therapy with other investigational products is permitted with certain restrictions. 6. Females who are pregnant or nursing or who plan to get pregnant during the EAP or within 6 months of the end of this trial. 7. Females of child-bearing potential, or men, who are unwilling or unable to use accepted methods of birth control. 8. History of gold allergy. OR These exclusion criteria will not be applied if the participant was previously enrolled in the HEALEY Platform ALS trial (Regimen C) Open Label Extension (NCT04414345).
