SALT LAKE CITY, Aug. 14, 2023 (GLOBE NEWSWIRE) — 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 revolutionizing the treatment of neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and multiple sclerosis (MS), today announced its second quarter 2023 financial results and provided recent operating highlights for the clinical programs in ALS and MS.

“Our recent financing has strengthened our capital position and provided the runway needed to advance our ALS clinical program with upcoming engagement with regulatory agencies, the initiation of our global Phase 3 in ALS (RESTORE-ALS), and additional clinical trial data read-outs,” said Rob Etherington, President and CEO of Clene. “We look forward to additional long-term clinical data, including survival, time-to-clinical-worsening and additional biomarker data, from the HEALEY ALS Platform trial. We are actively preparing for ALS regulatory discussions with the FDA and EMA, with meetings anticipated later this year. Additionally, we plan to continue advancing our clinical program in MS, while pursuing prospective partnering opportunities in parallel.”

Second Quarter 2023 and Recent Operating Highlights

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

• Results of the Phase 2 RESCUE ALS study and its open-label extension trial were published in the Lancet journal, eClinicalMedicine. The article can be accessed via the following link: https://authors.elsevier.com/sd/article/S2589537023002134.
• Clene reported that CNM-Au8 treatment demonstrated significantly reduced plasma NfL levels compared to placebo at 24 weeks (p=0.04). The results are based on an analysis of the plasma NfL biomarker across all Regimen C participants (CNM-Au8 or placebo, n=161) from the HEALEY ALS Platform trial.

CNM-Au8 for the treatment of MS

Clene received a one-year grant from NMSS that will fund Cohort 2 of REPAIR-MS, a Phase 2 clinical study investigating target engagement of CNM-Au8 in patients with non-active progressive MS. Using non-invasive brain imaging, the study will enroll up to 15 individuals with primary progressive or non-active secondary progressive MS and determine the effects of 12 weeks of daily oral dosing with CNM-Au8 on critical brain energy metabolites that have been shown to be compromised in individuals with MS.

Corporate Updates

On June 21, 2023, Clene announced the closing of its underwritten public offering. This financing raised gross proceeds of $40 million with potentially up to an additional $130 million in proceeds through future warrant exercises with expiration dates accelerated following the satisfaction of regulatory milestones. The investment was led by Vivo Capital with participation from SymBiosis, Acuta Capital Partners, AIGH Capital, Serrado Capital LLC and other new biotech investors, with support from existing investors.

Second Quarter 2023 Financial Results

Clene’s cash, cash equivalents and marketable securities totaled $49.2 million as of June 30, 2023, compared to $23.3 million as of December 31, 2022. Clene expects that its resources as of June 30, 2023, will be sufficient to fund its operations through mid-2024.

Research and development expenses were $6.6 million for the quarter ended June 30, 2023, compared to $9.2 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, RESCUE-ALS, REPAIR-MS, REPAIR-PD, and VISIONARY-MS clinical trials.

General and administrative expenses were $3.9 million for the quarter ended June 30, 2023, compared to $4.5 million for the same period in 2022. The year-over-year decrease was primarily attributable to decreases in directors’ and officers’ insurance fees and personnel expenses. These decreases were offset by an increase in finance and accounting fees, primarily due to increased fees from auditors, consultants, advisors and other financial vendors.

Total other expense was $14.8 million for the quarter ended June 30, 2023, compared to total other income of $9.1 million for the same period in 2022. The year-over-year increase in other expense was primarily attributable to an increase in interest expense, primarily due to increasing interest rates and increased amortization of debt discount and debt issuance costs on notes payable, changes in the fair value of contingent earn-out liabilities and changes in the fair value of common stock warrant liabilities offset by increased interest income. Additionally, in 2023 there was a loss on initial issuance of equity and charges for issuance costs related to the closing of the $40 million underwritten public offering in June 2023 that did not occur in 2022.

Clene reported a net loss of $25.1 million, or $0.29 per share, for the quarter ended June 30, 2023, compared to a net loss of $4.5 million, or $0.07 per share, for the same period in 2022.
