Clene Reports First Quarter 2023 Financial Results and Recent Operating Highlights

• ALS biomarker and long-term clinical data expected mid-year
• Neurology expert Ben Greenberg, M.D., M.H.S., joined as Head of Medical

SALT LAKE CITY, May 12, 2023 (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 diseases, today announced its first quarter 2023 financial results and provided recent operating highlights for the clinical programs in amyotrophic lateral sclerosis (“ALS”) and multiple sclerosis (“MS”).

“Clene is approaching several important data milestones in ALS,” said Rob Etherington, President and CEO of Clene. “These include key biomarker data that may support accelerated FDA approval as well as additional long-term survival data from both the HEALEY ALS Platform trial and our RESCUE ALS open-label extension trial. These data will inform our regulatory strategy as we plan ahead for our end-of-Phase 2 meeting with the FDA in the third quarter. In parallel, we are planning to advance regulatory discussions about MS anticipated in the fourth quarter and continue our pursuit of opportunities to establish a partnership for this program.”

First Quarter 2023 and Recent Operating Highlights

CNM-Au8^®, a gold nanocrystal suspension, for the treatment of ALS

A poster entitled “Evidence for Survival Benefit in ALS with CNM-Au8 Treatment Across Three Study Populations” was presented on April 25^th by Dr. James Berry at the American Academy of Neurology conference and included the following highlights:

• Survival in Early-to-Mid Stage ALS: CNM-Au8 30 mg demonstrated a statistically significant survival benefit of 60% and decreased risk of death through 120 weeks versus original placebo randomization in during follow-up of participants in the RESCUE-ALS trial .
• Survival in Mid-to-late stage ALS: CNM-Au8 30mg was associated with risk adjusted survival benefit of >90% and decreased risk of death through 24 weeks versus placebo in participants with mid-to-late stage ALS in the HEALEY ALS Platform trial.
• Survival from real world experience in ALS: CNM-Au8 30mg demonstrated observed median survival of more than three years in analyses of two compassionate use expanded access protocols.

CNM-Au8 for the treatment of MS

A platform presentation entitled “VISIONARY MS Top-line Results: A Phase 2, Randomized, Double-Blind, Parallel Group, Placebo-controlled Study to Assess the Safety and Efficacy of CNM-Au8, a Catalytically Active Gold Nanocrystal Suspension in Relapsing Multiple Sclerosis” was presented on April 25th by Dr. Michael Barnett at the American Academy of Neurology and included the following highlights:

• The primary and secondary endpoints demonstrated improved clinical outcomes in the mITT population, independent of an immunomodulatory effect.
• The prespecified exploratory MRI findings provide evidence of brain neuronal structural integrity assessed by diffusion tensor imaging (DTI) that demonstrated statistically significant results for key metrics of axonal integrity and white matter integrity. Preservation of white matter integrity is generally associated with decreased cognitive and functional decline in MS patients.                                                                                         
• CNM-Au8 was well-tolerated, and no significant safety findings were observed.

Corporate Updates

• On March 3, Clene entered into a purchase agreement with Lincoln Park Capital Fund, LLC (“Lincoln Park”) pursuant to which Lincoln Park has committed to purchase up to $25 million of shares of the Company’s common stock at the Company’s sole discretion, from time to time over a 36-month period.
• On March 16, Clene appointed neurology expert Benjamin Greenberg, M.D., M.H.S., as Head of Medical.

First Quarter 2023 Financial Results

Clene’s cash, cash equivalents and marketable securities totaled $18.4 million as of March 31, 2023, compared to $23.3 million as of December 31, 2022. Clene expects that its resources as of March 31, 2023, will be sufficient to fund its operations into the third quarter of 2023.

Research and development expenses were $7.4 million for the quarter ended March 31, 2023, compared to $8.6 million for the same period in 2022. The year-over-year decrease was primarily related to decreases in development costs of CNM-Au8 in the HEALEY ALS Platform Trial and the REPAIR-PD and VISIONARY-MS trials due to completion of the blinded period of each trial, a decrease in development costs of CNM-ZnAg due to the completion of our COVID-19 trial in 2022, and a decrease in personnel expenses due to a reduction in headcount during the fourth quarter of 2022, partially offset by increases in rent expense for the newly-leased facility in Elkton, Maryland, and increases in stock-based compensation primarily due to the timing of award grants, vesting, and forfeitures.

General and administrative expenses were $3.4 million for the quarter ended March 31, 2023, compared to $4.8 million for the same period in 2022. The year-over-year decrease was primarily attributable to lower finance and accounting fees, insurance costs, legal expenses, personnel expenses and stock-based compensation.

Total other income (expense) was ($1.0) million for the quarter ended March 31, 2023, compared to ($18,000) for the same period in 2022. The year-over-year increase in other expense was primarily attributable to an increase in interest expense due to increasing interest rates and an increase in our overall debt balances, a gain on termination of an operating lease in 2022 that did not repeat in 2023, the expense for shares issued to Lincoln Park as an initial fee for their commitment under a purchase agreement in 2023, and a decrease in realized gains on foreign currency transactions and other miscellaneous income, offset by increased interest income primarily due to increasing rates on cash, cash equivalents and marketable investment securities.

Clene reported a net loss of $11.8 million, or $0.15 per share, for the quarter ended March 31, 2023, compared to a net loss of $13.4 million, or $0.21 per share, for the same period in 2022.
