Clene Announces Completion of Patient Enrollment in the HEALEY ALS Platform Trial

• Registration trial for CNM-Au8®, a gold nanocrystal suspension
• Topline data anticipated 2H 2022
• World’s first ALS platform trial accelerating the path to new ALS therapies

SALT LAKE CITY, Nov. 15, 2021 (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 with potential first-in-class nanotherapeutics, today announced the completion of enrollment in the HEALEY ALS Platform Trial, led by the Sean M. Healey & AMG Center for ALS at Massachusetts General Hospital. Clene’s lead drug candidate, CNM-Au8®, a gold nanocrystal suspension, which has received U.S. Food and Drug Administration (FDA) Orphan Drug designation for the treatment of amyotrophic lateral sclerosis (ALS), is one of several drugs being evaluated in this innovative platform trial.

“We are grateful to people living with ALS, whose support and participation have made possible the completion of this critical milestone for this first-of-its-kind platform trial. This achievement is pivotal for trial completion and result reporting, paving the way to continue groundbreaking research and find life-saving treatments for people with ALS,” said Merit Cudkowicz, MD, MSc, Principal Investigator and Sponsor of the HEALEY ALS Platform Trial, Director of the Sean M. Healey & AMG Center for ALS and chief of the Department of Neurology at Mass General, and the Julieanne Dorn Professor of Neurology at Harvard Medical School.

“Having reached this significant milestone, we look forward to completing the 24-week, double-blind treatment phase and the release of top-line unblinded data in the second half of 2022. If CNM-Au8 meets its primary endpoint in this registration trial, we plan to file a New Drug Application with the FDA for disease-modification in ALS also in the second half of 2022. By catalyzing cellular energy metabolism, we believe CNM-Au8 may improve outcomes for ALS patients who currently have few treatment options,” said Robert Glanzman, MD, Chief Medical Officer of Clene.

The HEALEY ALS Platform Trial is a multi-center clinical program evaluating the safety and efficacy of multiple investigational products in ALS patients. It is the first ever platform trial implemented in ALS and was designed with a shared placebo arm 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 is currently being conducted at more than 50 expert ALS clinical trial sites across the U.S.

Clene’s CNM-Au8, a catalytically active gold nanotherapeutic, was selected by the Healey Center Therapy Selection Committee to be one of the first entrants into the trial. In the CNM-Au8 treatment regimen, at least 160 participants were randomized 3:1 (active:placebo), with 120 planned for randomization across two active arms (CNM-Au8 30 mg and 60mg) and at least 40 planned in placebo. Clinical data from an additional 80 placebo-treated participants are shared within the platform trial from two other regimens for an overall 1:1 allocation of active:placebo.

About CNM-Au8®, a gold nanocrystal suspension

Clene’s lead drug candidate, CNM-Au8, a catalytically active gold nanotherapeutic, is the result of a patented manufacturing breakthrough. The catalytically active nanocrystals of CNM-Au8 drive critical cellular energy producing reactions in the brain that enable neuroprotection and remyelination by increasing neuronal and glial resilience to disease-relevant stressors. CNM-Au8 crosses the blood-brain barrier and is not associated with the toxicities related to synthetic gold compounds or nanoparticles manufactured via alternative methods. CNM-Au8 is being evaluated in a Phase 3 registration trial for the treatment of amyotrophic lateral sclerosis (ALS). In the REPAIR Program Phase 2 open-label biomarker clinical trials, CNM-Au8 demonstrated target engagement in the treatment of Parkinson’s disease (PD) and multiple sclerosis (MS). REPAIR-PD has concluded, and REPAIR-MS will continue with the initiation of a second MS dosing cohort. 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 numerous disease-relevant neurotoxins. Oral treatment with CNM-Au8 improved functional behaviors in rodent models of ALS, MS and PD versus vehicle (placebo). CNM-Au8® is a federally registered trademark of Clene Nanomedicine, Inc.

About the HEALEY ALS Platform Trial

The HEALEY ALS Platform Trial is a perpetual multi-center, randomized, double-blind, placebo-controlled Phase 3 registration program designed to evaluate the efficacy and safety of multiple investigational products in people living with amyotrophic lateral sclerosis (ALS). Funded by philanthropic donors and led by Harvard’s Massachusetts General Hospital, the HEALEY ALS Platform Trial is the first-ever platform trial in ALS and was designed to reduce trial time, costs, and increase patient participation in developing novel therapies. This landmark platform trial tests multiple treatments utilizing a shared placebo group. CNM-Au8 was selected as one of the first three drugs to be evaluated. Participants are randomized 3:1 to receive one of three active treatments or placebo daily for a 24-week treatment period which is followed by an Open Label Extension where all participants receive active drug. The primary endpoint is rate of 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. Topline data are expected in 2H 2022. For more information, please see ClinicalTrials.gov Identifier: NCT04297683.

About Clene

Clene is a clinical-stage biopharmaceutical company focused on revolutionizing the treatment of neurodegenerative disease with potential first-in-class nanotherapeutics to treat energetic failure, an underlying cause of many neurological diseases. Our lead drug candidate, CNM-Au8, is an oral suspension of gold nanocrystals that drive critical cellular energetic metabolism in the central nervous system (CNS). CNM-Au8 increases energy production and utilization to accelerate neurorepair and improve neuroprotection. CNM-Au8 is currently being evaluated in a Phase 3 registration trial in amyotrophic lateral sclerosis (ALS) and a Phase 2 trial for the treatment of chronic optic neuropathy in patients with stable relapsing multiple sclerosis (MS). Clene has also advanced into the clinic an aqueous solution of ionic zinc and silver for anti-viral and anti-microbial uses. The company is based in Salt Lake City, Utah, with R&D and manufacturing operations in Maryland. For more information, please visit www.clene.com or follow us on Twitter, LinkedIn and Facebook.
