SALT LAKE CITY, Feb. 24, 2022 (GLOBE NEWSWIRE) -- Clene Inc. (NASDAQ: CLNN) along with its subsidiaries “Clene” and its wholly owned subsidiary Clene Nanomedicine, Inc., a clinical-stage biopharmaceutical company focused on revolutionizing the treatment of neurodegenerative disease, today announced the presentation of updated blinded interim data from its VISIONARY-MS study and results from its REPAIR-MS study in poster presentations at the Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) Forum 2022, taking place Feb. 24-26, 2022, in West Palm Beach, Fla. These data further support Clene’s lead drug candidate, CNM-Au8®, a catalytically active gold nanocrystal suspension, as a potential disease-modifying therapy for Multiple Sclerosis (MS).
The first poster, titled “VISIONARY-MS: Update to a Phase 2 Clinical Trial of CNM-Au8, Catalytically Active Gold Nanocrystal Suspension, for the Treatment of Chronic Optic Neuropathy,” includes updated blinded data from the ongoing VISIONARY-MS Phase 2 clinical trial evaluating the efficacy and safety of CNM-Au8 as a remyelinating and neuro-reparative treatment in MS patients. In this Phase 2 study, the efficacy and safety of CNM-Au8 (15 mg or 30 mg daily) versus placebo is being evaluated in stable relapsing MS patients with chronic optic neuropathy who are currently receiving disease-modifying therapy (DMT).
Blinded analyses presented compared changes in the overall study population's modified Multiple Sclerosis Functional Composite (mod-MSFC) values over the 48-week treatment period to the baseline values of study participants with mild disease as defined by pre-treatment Expanded Disability Status Scale (EDSS) scores of 1.5 or less. Changes in the four mod-MSFC domains (low contrast letter acuity (LCLA), symbol digit modalities test (SDMT), 9-hole peg test (9HPT) and timed 25-foot walk test (T25FWT) were compared to baseline scores of the mild disease comparator group at Weeks 12, 24, 36, and 48. At each visit, the overall study population (randomized 2:1, active CNM-Au8 to placebo) mean standardized change showed increasing improvements for LCLA (primary endpoint, mixed-effects model; p<0.0001 vs. baseline); averaged MSFC scores (secondary endpoint, mixed-effects model; p<0.0001 vs. baseline); and individual MSFC domains, including SDMT (p<0.0001 vs. baseline), 9HPT dominant-hand (p<0.001 vs. baseline), and 9HPT non-dominant hand (p<0.002). These data support CNM-Au8’s potential to drive meaningful neurological improvements in stable relapsing MS patients.
The second poster, titled “Improvement of Brain Energy Metabolism in Relapsing Multiple Sclerosis Patients: Results from Phase 2 REPAIR-MS Clinical Trial With CNM-Au8,” demonstrated that utilizing high-resolution magnetic resonance spectroscopy (31P-MRS) in stable relapsing MS patients, CNM-Au8 showed CNS target engagement resulting in improved brain energetic metabolism.
In the pre-specified integrated analysis across two identical clinical trials (REPAIR-MS and REPAIR-PD), the results for the primary endpoint, mean change in brain NAD+/NADH ratio (the ratio of the oxidized to reduced form of nicotinamide adenine dinucleotide), demonstrated a statistically significant increase of
“The results of the REPAIR-MS trial demonstrate the ability of CNM-Au8 to enter the brain and address energetic failure, a key driver in the pathophysiology of MS and other neurodegenerative diseases,” said Dr. Robert Glanzman, FAAN, Chief Medical Officer at Clene. “These mechanistic results support the blinded interim VISIONARY-MS data, which we believe suggest that CNM-Au8 has the potential to drive clinically meaningful improvements in recognized MS functional endpoints when administered in addition to standard of care. We look forward to sharing the unblinded data from VISIONARY-MS in the second half of 2022 that will help inform the design of our next clinical trial in MS patients.”
The posters are available on the Posters & Presentations section of the Clene website.
About VISIONARY-MS
VISIONARY-MS is a Phase 2 multi-center, randomized, double-blind, placebo-controlled trial evaluating the efficacy and safety of CNM-Au8 for remyelination and neurorepair in stable relapsing multiple sclerosis (MS) patients with chronic visual impairment who are allowed disease-modifying therapy (DMT). The primary endpoint is improvement in Low Contrast Letter Acuity (LCLA) from baseline to week-24. Key secondary endpoints include improvements from baseline to week-24 in the remaining modified-Multiple Sclerosis Functional Composite (MSFC) subscales (Symbol Digit Modalities Test, 9-Hole Peg Test, and Timed 25-Foot Walk). Unblinded top-line data are targeted for the second half of 2022. For more information, see ClinicalTrials.gov Identifier: NCT03536559.
About REPAIR-MS
REPAIR-MS is a Phase 2 single-center, active-only, sequential group study examining the brain metabolic effects, safety, pharmacokinetics and pharmacodynamics of CNM-Au8 in patients diagnosed with multiple sclerosis (MS) within 15 years of screening. Investigators and participants are blinded to dose. Participants undergo 31P-MRS brain imaging scans to semi-quantitatively measure central nervous system (CNS) energetic metabolites at baseline, prior to administration of CNM-Au8, and following at least 12 weeks of exposure. The objective of the study is to demonstrate target engagement for CNM-Au8 on CNS biomarkers related to energetics and neuronal membrane stability in patients with MS. The study is conducted 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. For more information see ClinicalTrials.gov Identifier: NCT03815916.
