Clene Inc. Presents New Preclinical Data Showing CNM-Au8 Improves Mitochondrial Health in Parkinson's Disease Models

Clene Inc. has presented new preclinical data showing its lead investigational therapy CNM-Au8 improves mitochondrial health and cellular function in Parkinson's disease models. The findings, presented at the Michael J. Fox Foundation's H2 Therapeutics Stewardship Meeting, demonstrate the drug candidate's ability to address key cellular deficits driving Parkinson's progression. According to the research, the therapy improved mitochondrial health, restored cellular metabolism, reduced inflammation, and normalized gene expression in dopaminergic neurons. These preclinical results align with previous Phase 2 trial data that showed positive energetic and metabolic effects in Parkinson's patients, suggesting consistency across study models.

CNM-Au8 demonstrated no toxicity in neuronal models, consistent with safety data accumulated from over 1,000 patient-years in amyotrophic lateral sclerosis and multiple sclerosis clinical trials. This safety profile supports further clinical development for neurodegenerative conditions where mitochondrial dysfunction plays a critical role. The company plans to design a Phase 2 clinical study specifically for Parkinson's disease while continuing to advance its programs for ALS and MS. The research highlights CNM-Au8's potential mechanism of action in improving cellular energy production and reducing neuroinflammation, both key factors in Parkinson's disease pathology.

These findings build upon growing evidence that targeting mitochondrial health could represent a novel therapeutic approach for neurodegenerative diseases. The data was announced earlier in September 2025 and detailed the drug's potential to address key cellular and energetic deficits that drive disease progression according to information available at https://ibn.fm/EECHU. The implications of this research are significant for the Parkinson's disease community, as current treatments primarily address symptoms rather than underlying disease progression. By targeting mitochondrial dysfunction and cellular energy deficits, CNM-Au8 represents a potential disease-modifying approach that could slow or halt Parkinson's progression.

The consistency between preclinical models and previous human trial data strengthens the scientific rationale for further clinical development. The established safety profile from other neurodegenerative disease trials provides additional confidence for advancing CNM-Au8 specifically for Parkinson's disease. This research matters because Parkinson's disease affects approximately one million people in the United States alone, with current treatments offering limited disease-modifying benefits. The potential to address fundamental cellular dysfunction represents an important advancement in neurodegenerative disease research and could establish a new therapeutic paradigm for conditions characterized by mitochondrial impairment.
