Clene Inc. and its wholly owned subsidiary Clene Nanomedicine Inc. announced that The Lancet’s journal eClinicalMedicine has published combined detailed analyses of the Phase 2 RESCUE-ALS study and its open-label extension trial. RESCUE-ALS was a Phase 2 multi-center, randomized, double-blind, parallel-group, placebo-controlled trial, investigating the efficacy, safety, pharmacokinetics and pharmacodynamics of CNM-Au8 in 45 participants (73% limb onset, 27% bulbar onset) with early ALS over a 36-week treatment period. The primary endpoint was the percent change in the summated motor unit index (MUNIX) scores to week 36.

The primary blinded comparative period was followed by an open-label extension (OLE) in which all participants received 30 mg of CNM-Au8 once-daily, with 90% (36 of 45 patients) entering the OLE. Clene announced topline results for RESCUE-ALS on November 2, 2021. CNM-Au8 is an oral suspension of gold nanocrystals developed to restore neuronal health and function by increasing energy production and utilization.

The catalytically active nanocrystals of CNM-Au8 drive critical cellular energy producing reactions that enable neuroprotection and remyelination by increasing neuronal and glial resilience to disease-relevant stressors. CNM-Au8® is a federally registered trademark of Clene Nanomedicine Inc.
