This is a multi-centre randomised, double-blind, parallel group, placebo-controlled study of the efficacy, safety, pharmacokinetics, and pharmacodynamics of CNM-Au8 in patients who are newly symptomatic within 24-months of Screening and with a clinically probable or possible or definite ALS diagnosis per the Awaji-Shima criteria (de Carvalho et al. 2008).
Patients may be screened over up to a 4-week period. Patients who meet the inclusion criteria and none of the exclusionary criteria will be enrolled into the clinical study.
Patients will be randomised 1:1 into one of two groups: either active treatment with CNM-Au8 30 mg or Placebo.
All patients will receive their randomised oral treatment daily over thirty-six (36) consecutive weeks during the Treatment Period.
There will be three study periods:
- Up to a four (4) week screening period (Screening Period);
- A thirty-six (36) week blinded randomised treatment period (Treatment Period);
- A four (4) week safety follow-up period (End-of-Study Assessment).
Per protocol all patients will receive their blinded and randomised oral treatment daily over at least 36 consecutive weeks during the Treatment Period. Following the end of the Treatment Period patients may be transitioned into an open-label extension period in a separate study protocol (e.g., RESCUE-ALS OLE).
For those patients not transitioning into the separate open-label extension study, patients will complete an EOS safety assessment 4-weeks following study drug discontinuation.
An independent DSMB will be responsible for monitoring the safety of the study on a quarterly basis and ad hoc at the request of the DSMB or the Sponsor (e.g., in the event of unexpected SAEs) to review data throughout the Treatment Period. The DSMB may make recommendations on the conduct of the study, including study termination.
Appropriate procedures will be detailed in a DSMB Charter.
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||42 participants|
|Intervention Model:||Parallel Assignment|
|Intervention Model Description:||randomized, double-blind, parallel group, placebo-controlled study|
|Masking:||Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)|

Placebo Comparator: Placebo
The matched placebo to be used in this study will consist of water, sodium bicarbonate, and food coloring to match volume and color of the experimental treatment
Placebo is liquid with identical color and taste
Experimental: 30 mg CNM-Au8
30mg suspension of clean-surfaced, faceted, gold nanocrystals in 60ml of sodium bicarbonate buffered water
CNM-Au8 is a dark red/purple-colored liquid formulation consisting of a stable suspension of faceted clean surfaced elemental gold nanocrystals in buffered deionized water with a nominal concentration of 0.5 mg/mL of gold. The formulation is buffered by sodium bicarbonate present at a concentration of 0.546 mg/mL. There are no other excipients. The drug product is formulated to be taken orally and will be provided in single dose 60 mL HDPE containers.
