CLENE REPORTS SIGNIFICANT LONG-TERM SURVIVAL IMPROVEMENT

FROM CNM-Au8 TREATMENT IN HEALEY ALS PLATFORM TRIAL

COMPARED TO PRO-ACT HISTORICAL CONTROLS

SALT LAKE CITY, Sept. 25, 2023 -- Clene Inc. (Nasdaq: CLNN) through its wholly owned subsidiary Clene Nanomedicine, Inc. (collectively “Clene”), today announced long-term follow-up data for patients treated with CNM-Au8® 30mg for up to 133 weeks in the HEALEY ALS Platform Trial. These post hoc results show significantly improved survival with a 49% decreased risk of death for the covariate risk-adjusted analyses compared to the largest U.S. clinical database of previous amyotrophic lateral sclerosis (ALS) trials (PRO-ACT) (hazard ratio: 0.510, 95% CI: 0.263 - 0.987, p=0.046).

The HEALEY ALS Platform Trial is a perpetual multi-center, randomized, double-blind, placebo-controlled clinical trial program designed to evaluate the efficacy and safety of multiple investigational products in people living with ALS. Enrollment in the CNM-Au8 Regimen was initiated in the summer of 2020. Participants received CNM-Au8 in addition to ALS standard-of-care and were randomized to the drug or placebo during the 24-week double-blind period. CNM-Au8 was then offered to all participants who were eligible, and 92% elected to continue into the Open Label Extension (OLE). CNM-Au8 30mg was selected as the dosage going forward after the double-blind period.

In ALS, clinical studies with shorter double-blind treatment duration such as 24 weeks have used historical placebo controls from prior trials to determine the relative survival benefit of investigational treatment over longer-term follow-up (open label data). The PRO-ACT dataset is derived from pooled ALS clinical trial data from 29 completed Phase 2 and Phase 3 ALS clinical trials. Millions of de-identified longitudinally collected records from more than 11,600 individuals with ALS were standardized across trials and merged to create the Pooled Resource Open-Access ALS Clinical Trials (PRO-ACT) database. This database provides a useful and validated surrogate for survival status of past participants in ALS clinical trials with long-term follow-up.

In this analysis, 59 participants who were originally randomized to CNM-Au8 30mg were compared to matched placebo participants derived from the PRO-ACT dataset:

Survival Improvement

Safety

Benjamin Greenberg, M.D., Head of Medical at Clene, added, “To show such profound survival improvement using the HEALEY ALS Platform Trial data set alone and a pooled HEALEY and RESCUE data set is remarkable, and helps confirm the survival benefit seen in the prespecified secondary endpoint. Clene is extremely gratified to see this consistent long-term survival data from the HEALEY ALS Platform Trial OLE, with a continued clean safety profile, adding to the totality of the survival evidence.”

Merit Cudkowicz, M.D., Chair, Neurology Department, Massachusetts General Hospital, Director, Sean M Healey & AMG Center for ALS, and the Principal Investigator of the HEALEY ALS Platform Trial, said, “Improved survival status is an important measure of drug effect. We previously reported a benefit for decreased risk of death or permanent assisted ventilation and delayed time-to-clinical-worsening events associated with CNM-Au8 30mg from the double-blind period, and we are pleased to see these data from our long-term follow-up as further support of a survival signal in our HEALEY ALS Platform Trial.” She concluded, “I am also happy to see how helpful a shared open-source dataset such as PRO-ACT is to the field to analyze data from the OLE portions of clinical trials. We encourage all companies working in ALS to contribute their data to PRO-ACT once their trial is complete. I want to also thank all the people with ALS who are part of clinical trials and are helping the community find new treatments.”
