SALT LAKE CITY, March 12, 2025 (GLOBE NEWSWIRE) -- Clene, Inc. (Nasdaq: CLNN) and its subsidiary, Clene Nanomedicine, Inc., a clinical-stage biopharmaceutical company focused on revolutionizing the treatment of neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and multiple sclerosis (MS), today announced new evidence from a cross-regimen, post hoc analysis of long-term survival in HEALEY ALS Platform Trial participants. The analyses further substantiate that treatment with CNM-Au8® 30 mg delivers a significant survival benefit for people living with ALS. New Survival Analyses The analyses compared survival in participants who received CNM-Au8 30 mg (Regimen C) to those of Regimen A in the HEALEY ALS Platform Trial. Regimen A provided a large concurrent control group vs. CNM-Au8 treatment using the same randomization criteria established within the HEALEY master protocol. Long-term survival status, determined through public records and site reporting, was evaluated over a follow-up period of up to 48 months. 78% of participants across both groups received standard ALS background therapy (riluzole, edaravone, or both) at baseline. Overall Survival Improvement (All-Cause Mortality) Across the Full Analysis Set: Median Survival: CNM-Au8 30 mg group (Regimen C, n=59) achieved 951 days versus 753 days in the Regimen A comparator group (n=162) – a gain of 198 days (6.5 months) Restricted Mean Survival Time (RMST) Benefit: covariate-adjusted RMST improvement of 124 days (4.1 months) was observed (95% CI: 3 to 245 days, p=0.045). RMST is a metric that estimates the average time a group survives relative to a comparator. The estimate incorporated the prespecified covariates for survival analyses from the HEALEY ALS Platform Trial (i.e., months from symptom onset, pre-treatment ALSFRS-R slope, age, background riluzole treatment, background edaravone treatment) Sensitivity analyses, which included additional covariate models such as baseline serum neurofilament light (NfL) levels, use of ALS background therapy, and the TRICALS risk score, confirmed the robustness and statistical significance of the findings Enhanced Benefit in Moderate to Severe ALS: In participants with baseline serum NfL > 33 pg/mL and TRICALS risk score range between –6.5 and –2.5 (i.e., filtering slow progressors where there was an imbalance between groups), median survival improved from 589 days (Regimen A, n=120) to 951 days (CNM-Au8 30 mg, n=51), representing an 11.9 month gain Mortality risk in this group decreased by 44% (Cox HR: 0.556, 95% CI: 0.367–0.842, p=0.006) with an RMST improvement of 197 days (6.5 month gain; 95% CI: 65 to 329 days, p=0.004), when using the prespecified covariates for survival analyses from the HEALEY ALS Platform Trial Median Survival: CNM-Au8 30 mg group (Regimen C, n=59) achieved 951 days versus 753 days in the Regimen A comparator group (n=162) – a gain of 198 days (6.5 months) Restricted Mean Survival Time (RMST) Benefit: covariate-adjusted RMST improvement of 124 days (4.1 months) was observed (95% CI: 3 to 245 days, p=0.045).

Healey & AMG Center for ALS, and executive director of the Mass General Brigham Neuroscience Institute, said, “The innovative design of the HEALEY ALS Platform Trial has enabled us to extract clear and meaningful survival data that helps make decisions about CNM-Au8 drug development.” About Regimen A Regimen A was one of the first three regimens investigated in the HEALEY ALS Platform Trial. Eligible participants were randomized in a 3:1 ratio to receive active treatment or matching placebo for a planned duration of 24 weeks. Participants assigned to Regimen A had to receive both quadrivalent and serotype B meningococcal vaccinations at least 14 days prior to the first dose of study drug, and participants were excluded from Regimen A if they had a history of meningococcal disease or prior treatment with a complement inhibitor. Regimen A was stopped prematurely for futility after all participants had been randomized, and approximately 70% had completed the Week 24 visit. Participants were instructed to discontinue study dosing, and a final early termination study visit was conducted. Long-term survival status of Regimen A participants was tracked from public records and site reporting independently of the early termination. There was no difference in long-term survival in participants randomized to Regimen A active compared to Regimen A placebo, supporting the combined analyses of the entire Regimen A population for comparisons of long-term survival to CNM-Au8 30 mg (Regimen C) participants.

About RESTORE-ALS RESTORE-ALS is a Phase 3 confirmatory global, multi-center, randomized, double-blind, parallel group, placebo-controlled study to evaluate the efficacy, safety, pharmacodynamics, and pharmacokinetics of CNM-Au8 in participants diagnosed with ALS on stable background therapy. The study is designed to investigate the effects of CNM-Au8 on improved survival (primary endpoint) and delayed time to ALS clinical worsening events (secondary efficacy endpoint). Participants will be randomized in a 2:1 ratio to receive either active treatment with CNM-Au8 30 mg or matched placebo daily during the 108-week double-blind treatment period. The Phase 3 RESTORE-ALS clinical trial, due to launch in mid-2025, is planned to serve as the confirmatory clinical trial required to meet the FDA’s guidance for an “underway” clinical trial when a New Drug Application requesting Accelerated Approval is submitted.
