Exhibit 99.1

CLENE REPORTS THIRD QUARTER 2023 FINANCIAL RESULTS AND OPERATING HIGHLIGHTS

● Reported statistically significant improved survival benefit of 19.3 months and significantly delayed clinical worsening in patients treated with CNM-Au8^® in the RESCUE ALS open-label extension trial

● Reported statistically significant long-term survival benefit of 70% decreased risk of death associated with CNM-Au8 treatment in the HEALEY ALS Platform Trial compared to PRO-ACT historical controls

● Awarded $45.1 million NINDS grant to support research and expanded access of CNM-Au8 in people living with ALS

● Announced peer-reviewed publication characterizing CNM-Au8 neuroprotective mechanism of action in the nanotechnology-focused journal, Small

● Cash and cash equivalents of $42.1 million as of September 30, 2023, which includes gross proceeds of $40 million from a public offering in June and that may provide additional capital of up to $130 million through future warrant exercises based on regulatory milestones

SALT LAKE CITY, November 7, 2023 -- Clene Inc. (Nasdaq: CLNN) (along with its subsidiaries, “Clene”) and its wholly owned subsidiary Clene Nanomedicine Inc., a late clinical-stage biopharmaceutical company focused on improving mitochondrial health and protecting neuronal function to treat neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS), Parkinson’s disease and multiple sclerosis (MS), today announced its third quarter 2023 financial results and provided recent operating highlights for its ALS clinical program.

“We are pleased to be approaching a meaningful regulatory discussion with the U.S. Food and Drug Administration (FDA) later in the fourth quarter to elucidate key next steps in our ALS regulatory submission of CNM-Au8,” said Rob Etherington, President and CEO of Clene. “We are hopeful that the consistent survival, delayed time to clinical worsening and strong safety profile with CNM-Au8 treatment from two phase 2 independent trials is sufficiently compelling for FDA to consider an accelerated path forward. The unmet need remains high for treatments to improve and extend life for patients living with this highly debilitating and rapidly progressive condition.”

Third Quarter 2023 and Recent Operating Highlights

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

● In August, Clene reported 24-month data from the open-label extension of the Phase 2 RESCUE ALS study which showed a significant median survival benefit of 19.3 months, a 75% decreased risk of long-term all-cause mortality and a significant 52% decreased risk (p=0.049) of ALS clinical worsening events in patients originally randomized to CNM-Au8 treatment.

● In September, Clene announced long-term follow-up data for patients treated with CNM-Au8 for up to 133 weeks in the HEALEY ALS Platform Trial. These post hoc data demonstrate significantly improved survival with a 49% decreased risk of death compared to a group of historical controls, who were included in the largest U.S. clinical database of previous ALS trials (PRO-ACT).

● In October, Clene, in collaboration with Columbia University and Synapticure, was awarded a four-year grant totaling $45.1 million from the National Institute of Neurological Disorders and Stroke (NINDS), a division of the National Institutes of Health (NIH), to support an Expanded Access Protocol (EAP) for the Company’s investigational drug, CNM-Au8, in ALS.

Corporate Update

In September, the Company announced the publication of a scientific paper describing the catalytic mechanism of action (MOA) of its investigational drug, CNM-Au8 in the journal Small, a top nanotechnology-focused journal at the interface of materials science, chemistry, physics, engineering, medicine, and biology. The publication titled “A Mechanism Underpinning the Bioenergetic Metabolism-Regulating Function of Gold Nanocatalysts” characterizes the robust neuroprotective properties of CNM-Au8, which are related to the compound’s therapeutic catalytic activity. Because of the unique MOA of CNM-Au8 and the wide applicability of its neuroprotective activities, the drug is being studied across multiple neurodegenerative diseases including ALS, MS and Parkinson’s Disease.

The publication is available via Open Access at https://onlinelibrary.wiley.com/doi/10.1002/smll.202304082.

Third Quarter 2023 Financial Results

Clene’s cash, cash equivalents and marketable securities totaled $42.1 million as of September 30, 2023, compared to $23.3 million as of December 31, 2022. Clene expects that its resources as of September 30, 2023, will be sufficient to fund its operations into the third quarter 2024.

Research and development expenses were $6.0 million for the quarter ended September 30, 2023, compared to $6.4 million for the same period in 2022. The year-over-year decrease was primarily related to a decrease in expenses related to our lead drug candidate, CNM-Au8, due to a decrease in clinical trial expenses in our HEALEY ALS Platform Trial and our RESCUE-ALS, REPAIR-MS, REPAIR-PD, and VISIONARY-MS clinical trials due to the completion of the blinded period of each trial, partially offset by increased expenses related to our ongoing EAPs and increased facility costs related to our newly-leased facility in Elkton, Maryland.

General and administrative expenses were $3.7 million for the quarter ended September 30, 2023, compared to $3.6 million for the same period in 2022. General and administrative expenses have remained flat year over year although directors’ and officers’ insurance fees and legal fees have decreased year over year while finance and accounting expenses related to fees from auditors, consultants and other financial vendors have increased and personnel fees have increased.

Total other income was $7.1 million for the quarter ended September 30, 2023, compared to total other expense of $1.2 million for the same period in 2022. The year-over-year increase in other income was primarily attributable to the changes in the fair value of common stock warrant liabilities and contingent earn-out liabilities as well as an increase in interest income.

Clene reported a net loss of $2.4 million, or $0.02 per share, for the quarter ended September 30, 2023, compared to a net loss of $11.0 million, or $0.17 per share, for the same period in 2022.
