Recent Achievements and Outlook

CNM-Au8 for the treatment of amyotrophic lateral sclerosis (ALS):

Blinded interim data from the Phase 2 RESCUE-ALS trial, as presented at the 31st International Symposium on ALS/MND:
Rescue-ALS is a Phase 2, multi-center, randomized, double-blind, placebo-controlled study designed to evaluate the efficacy, safety, pharmacokinetics and pharmacodynamics of CNM-Au8, a neuro-reparative nanocatalyst, in early symptomatic ALS patients. Enrollment in the trial was completed ahead of schedule in September 2020. Preliminary blinded data presented at the 31st International Symposium on ALS/MND show that more than 40% of enrolled patients with completed 12-week data experienced improvements in motor neuron function as assessed by the mean motor unit number index-4 [MUNIX(4)] score, the study’s primary endpoint. Compared to baseline values, the average MUNIX(4) score of the overall trial population (including both active CNM-Au8 and placebo) showed an absolute increase. This increase exceeded the expectations of the statistical models on which the study was based, which predicted a continuing linear decrease in average MUNIX(4) score from study onset (Neuwirth et al. JNNP 2015). These data, though blinded, suggest that CNM-Au8 may have neuro-reparative potential in ALS patients. Clene expects to report the complete, unblinded results from the RESCUE-ALS study in the second half of 2021.

Launched patient enrollment in the HEALEY ALS Platform Trial:
CNM-Au8 was selected as one of the first drug regimens to be evaluated in the HEALEY ALS Platform Trial, a multi-center, multi-regimen, placebo-controlled, Phase 3 registration trial evaluating the safety and efficacy of investigational products for the treatment of ALS. This first-ever ALS platform trial is designed to reduce trial time, reduce costs and increase patient participation in developing novel therapies for ALS. It includes substantial financial support from philanthropic donors and foundations and provides access to 54 expert ALS clinical trial sites across the U.S. Dosing was initiated in the Clene-specific portion of the platform trial in July 2020 and full enrollment is expected by the end of Q2 2021, with top-line data available in the first half of 2022.

CNM-Au8 for the treatment of multiple sclerosis (MS):

Blinded interim data from the Phase 2 VISIONARY-MS trial, as presented at the MSVirtual2020 Meeting:
VISIONARY-MS is a Phase 2, multi-center, double-blind, randomized, placebo-controlled trial evaluating the efficacy and safety of CNM-Au8 as a remyelinating and neuro-reparative treatment in stable relapsing MS patients with chronic visual impairment. Preliminary blinded data presented at the MSVirtual2020 Meeting demonstrated notable, exposure-related median improvements in low contrast letter acuity (the study’s primary endpoint), as well as the three remaining sub-scales of the modified MS Functional Composite: Symbol Digit Modalities Test (cognition), 9-Hole Peg Test (upper extremity function) and Timed 25-foot Walk (gait). The available safety data indicate that CNM-Au8 is well-tolerated with no drug-related serious adverse events reported to date. These data, though blinded, together provide support for the potential of CNM-Au8 to drive clinically meaningful improvements in MS visual and functional endpoints. Full enrollment in VISIONARY-MS is expected by the end of 2021, subject to ongoing COVID-19 related site research restrictions generally implemented to protect MS patients taking standard-of-care immunosuppressive therapies.

Interim data from the Phase 2 REPAIR-MS trial, as presented at the MSVirtual2020 Meeting:
REPAIR-MS is a single-center, active-only, sequential group, investigator-blinded study to assess the central nervous system (CNS) metabolic effects, safety, pharmacokinetics, and pharmacodynamics of CNM-Au8 in MS patients. An analysis of combined, interim results from REPAIR-MS and the concurrent REPAIR-PD trial demonstrate significant CNS target engagement of orally dosed CNM-Au8. The data also show improvements across important CNS bioenergetic metabolites, including total nicotinamide adenine dinucleotide (NAD+) levels, NAD+/NADH ratio, and adenosine triphosphate (ATP) levels, indicating a homeostatic effect of CNM-Au8 on brain bioenergetics. Such data provide evidence for the ability of CNM-Au8 to positively affect key metabolic markers in the human brain and highlight its potential to enhance fundamental cell processes through broadly applicable bioenergetic mechanisms. Clene expects to report additional data from REPAIR-MS in the second half of 2021.

CNM-Au8 for the treatment of Parkinson’s disease (PD):

Interim data from the Phase 2 REPAIR-PD trial, as presented at the MSVirtual2020 Meeting:
REPAIR-PD is a single-center, active-only, sequential group, investigator-blinded study to assess the CNS metabolic effects, safety, pharmacokinetics and pharmacodynamics of CNM-Au8 in PD patients. As discussed above, an analysis of combined, interim results from REPAIR-PD and REPAIR-MS studies were presented during the joint MSVirtual2020 Meeting. Clene expects to report additional data from REPAIR-PD in the first half of 2021 and to launch an additional Phase 2 PD efficacy trial by the end of 2021.

CNM-AgZn17 for the treatment of infectious diseases, including COVID-19:

Launching a Phase 2 trial in COVID-19 patients in Brazil:
CNM-AgZn17 is Clene’s second key asset intended for broad anti-viral and anti-microbial use. A Phase 2 study is planned for conduct in Brazil to treat acutely symptomatic non-hospitalized patients with COVID-19. This study will evaluate time to symptomatic improvement (up to 28 days) and prevention of hospitalization. This study is anticipated to launch in the first half of 2021.

RESCUE-ALS is a Phase 2 multi-center, randomized, double-blind, parallel-group, placebo-controlled study examining the efficacy, safety, pharmacokinetics and pharmacodynamics of CNM-Au8 in participants who are newly symptomatic with ALS (within 24-months of screening or 12-months from diagnosis). Enrolled subjects will be randomized 1:1 to receive either active treatment with CNM-Au8 (30 mg) or placebo in addition to their current standard of care. Participants will receive their randomized treatment over 36 consecutive weeks during the Treatment Period. The objective of this study is to assess the impact of improving neuronal bioenergetics, reducing reactive oxygen species and promoting protein homeostasis with CNM-Au8 to slow disease progression in patients with ALS.

About the HEALEY ALS Platform Trial
The HEALEY ALS Platform trial is a multi-center, randomized, double-blind, placebo-controlled Phase 2 study designed to evaluate the efficacy, safety, pharmacokinetics and pharmacodynamics of investigational products, including CNM-Au8, in early symptomatic ALS patients. It is the first ALS platform trial and is designed to accelerate the path to new ALS therapies by testing multiple treatments against a single placebo group. Enrolled subjects will be randomized 3:1 to receive either active treatment or placebo daily for a 24-week treatment period. The primary endpoint is change in disease severity over time as measured by the ALS Functional Rating Scale-Revised (ALSFRS-R). Secondary endpoints include change in respiratory function over time as measured by slow vital capacity and change in muscle strength over time as measured isometrically using hand-held dynamometry.

The objective of the VISIONARY-MS (Treatment of Visual Pathway Deficits In Chronic Optic Neuropathy for Assessment of Remyelination in Stable RMS) trial is to assess the efficacy and safety of CNM-Au8 as a neuroprotective and remyelinating treatment for people with stable relapsing MS who have chronic vision impairment. The primary endpoint is improvement in low contrast letter acuity from baseline to Week-24. Key secondary endpoints include improvements from baseline to Week-24 in the remaining modified-Multiple Sclerosis Functional Composite subscales (Symbol Digit Modalities Test, 9-Hole Peg Test, and Timed 25-Foot Walk). Participants drink a 2 oz. (60 ml) dose of the nanocrystal suspension (or placebo) daily each morning.

REPAIR-MS and REPAIR-PD are Phase 2, single-center, open-label, sequential group studies examining the brain metabolic effects, safety, pharmacokinetics and pharmacodynamics of CNM-Au8 in patients who have been diagnosed with MS within 15 years of screening or in patients with PD who have been diagnosed within three years of screening. Investigators and participants are blinded to dose, which can consist of a 15 or 30 mg orally delivered dose of the nanocrystal suspension daily each morning for 12 weeks. Participants undergo 31P-MRS brain imaging scans to semi-quantitatively measure bioenergetic brain metabolites at baseline, prior to administration of drug, and at the end-of-study. The objective of this study is to demonstrate target engagement for CNM-Au8 on CNS biomarkers related to bioenergetics and neuronal metabolism in patients with MS and PD. The study is taking place at the University of Texas Southwestern Medical Center with a team of internationally recognized experts in brain imaging and treatment of disorders of the CNS.

About CNM-Au8
CNM-Au8 is a concentrated, aqueous suspension of clean-surfaced faceted gold nanocrystals that act catalytically to support important intracellular biological reactions. CNM-Au8 consists solely of gold nanoparticles, composed of clean-surfaced, faceted, geometrical crystals held in suspension in sodium bicarbonate buffered, pharmaceutical grade water. CNM-Au8 has demonstrated safety in Phase 1 studies in healthy volunteers and has shown both remyelination and neuroprotective effects in multiple preclinical (animal) models. Preclinical data, both published in peer-reviewed journals and presented at scientific congresses, demonstrate that treatment of neuronal cultures with CNM-Au8 improves survival of neurons, protects neurite networks, decreases intracellular levels of reactive oxygen species and improves mitochondrial capacity in response to cellular stresses induced by multiple disease-relevant neurotoxins. Oral treatment with CNM-Au8 improved functional behaviors in rodent models of ALS, MS and Parkinson’s disease versus vehicle (placebo). CNM-Au8 is currently being tested in a Phase 2 clinical study for the treatment of chronic optic neuropathy in patients with MS, in addition to Phase 2 and Phase 3 clinical studies for disease progression in patients with ALS.
