Clene Inc. (NASDAQ: CLNN) is a late clinical-stage biopharmaceutical company focused on improving mitochondrial health and protecting neuronal function to treat neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS), Parkinson’s disease, and multiple sclerosis (MS).
Its lead drug candidate is CNM-Au8®, an oral suspension developed to restore neuronal health and function by increasing energy production and utilization by driving critical cellular energy producing reactions that enable neuroprotection and remyelination to increase neuronal and glial resilience to disease-relevant stressors. CNM-Au8 is being studied in various clinical trials, including the Harvard/MGH Healey ALS Platform clinical trial for patients with ALS; RESCUE-ALS, a completed proof-of-concept clinical trial in patients with early symptomatic ALS; the REPAIR trials, completed target engagement clinical trials showing brain energy metabolite change with CNM-Au8; and a completed MS clinical trial for the treatment of visual pathway deficits in chronic optic neuropathy for remyelination in stable relapsing MS. The company also has a nanotherapeutic platform of drug discovery.
CNM-Au8
CNM-Au8, Clene’s lead asset, is a highly concentrated aqueous suspension of catalytically active, clean-surfaced, faceted gold nanocrystals. Multiple pathogenic insults contribute to neuronal death. Mitochondrial dysfunction and NAD+ decline is a common final pathway in neurodegeneration, with NAD+ as a critical determinant of cell survival and function. CNM-Au8’s catalytic mechanisms target the energetic deficits, oxidative stress and accumulation of misfolded proteins that are common to many neurodegenerative diseases.
The unique catalytic mechanism of action of CNM-Au8 is hypothesized to act as a neuroprotective and remyelinating therapy in neurodegenerative disease states in order to: (1) drive, support and maintain beneficial metabolic and energetic cellular reactions within diseased, stressed and/or damaged cells, (2) directly catalyze the reduction of harmful, reactive oxygen species (“ROS”) and (3) promote protein homeostasis via activation of the heat shock factor-1 pathway, recognized to dampen the cytotoxicity caused by misfolded and denatured proteins, which are known to occur ubiquitously in neurodegenerative diseases.
CNM-Au8 is used in combination with other agents, has no known drug-drug interactions, and is designed to improve function and survival. The clinical effects of both function and survival were seen in its clinical ALS trials, as earlier announced.
More than 500 estimated years of collective exposure across ALS, MS, and Parkinson’s disease participants in CNM-Au8 clinical trials and Expanded Access Protocol (compassionate use) programs have been recorded without any observed safety signals.
CNM-Au8 is a federally registered trademark of Clene Inc. Clene, based in Salt Lake City, Utah, with R&D and manufacturing operations in Maryland, began in 2013.
Market Opportunity
ALS is the most prevalent adult-onset progressive motor neuron disease, affecting approximately 30,000 people in the U.S. and an estimated 500,000 people worldwide, with a life expectancy of typically three to five years. Clene estimates that global ALS treatment sales will be greater than $1 billion annually within the coming few years. Additional treatments affecting daily function and survival remain the market need.
Additionally, there are more than 2 million MS patients globally, and Clene estimates the market size to be worth more than $23 billion annually. While the MS community has been successful at limiting relapses, non-relapsing MS patients continue to clinically deteriorate even while receiving effective immunomodulatory disease-modifying therapies (“DMTs”). A critical unmet medical need remains for therapeutic interventions that protect neuronal function and myelin health independent of immunomodulation to address progression independent of relapse activity.

Investment Considerations
- Demonstrated prolonged life with 59% decreased risk of death in an integrated meta-analysis across the HEALEY ALS Platform Trial and RESCUE-ALS Trial with CNM-AU8 30 mg dose compared to PRO-ACT matched placebo over long-term follow-up (p=.004)
- 19.3 month survival difference for CNM-Au8 ALS treated participants versus placebo in RESCUE-ALS Trial
- Multiple near-term milestones, including both clinical and regulatory updates
- Potential to file New Drug Application with CNM-Au8 for ALS indication in the first half of 2024.
- Commercial opportunity for CNM-Au8 in ALS as early as second half of 2024, including potential FDA approval of NDA
- Sufficient cash to extend runway to the third quarter of 2024
- As of January 2023, Clene had more than 150 issued patents worldwide and approximately 20 patents pending worldwide on top of many trade secrets
