SALT LAKE CITY, Aug. 14, 2025 (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 2025 financial results, provided recent updates on its CNM-Au8 programs and announced sufficient cash runway into the first quarter of 2026.

“We look forward to engaging with the FDA in our upcoming meeting this quarter focused on the extensive survival data that CNM-Au8 has generated in ALS patients. We are also advancing activities necessary to analyze our NIH-sponsored EAP neurofilament light biomarker data, with results expected in the fourth quarter,” said Rob Etherington, President and CEO of Clene. “These meetings and biomarker analyses represent the final steps to our potential submission of an NDA under the accelerated approval pathway for ALS by the end of 2025. Our commitment to the ALS community remains unwavering as we endeavor to develop an impactful therapeutic agent for this devastating disease,” he concluded.

Second Quarter 2025 and Recent Operating Highlights

CNM-Au8 for the treatment of ALS
Clene held a productive Type C meeting with the U.S. Food and Drug Administration (FDA) to discuss its proposed statistical analysis methodology for assessing neurofilament light (NfL) biomarker changes from ALS patients enrolled in its National Institute of Health (NIH)-sponsored expanded access program (EAP). NfL change will be analyzed following 9 months of treatment (primary NfL analysis) and after 6 months of treatment (supportive NfL analysis). These analyses are intended to provide supportive data of the NfL change previously demonstrated in the HEALEY ALS Platform Trial double-blind period following 6 months of treatment with CNM-Au8. Clene expects to conduct the analysis of this NfL biomarker data early in the fourth quarter of 2025.

A second Type C meeting with the FDA to review the long-term survival benefit from CNM-Au8 30 mg treatment compared to concurrently randomized controls from another HEALEY ALS Platform Trial regimen, in addition to other survival data, is planned in the third quarter of 2025. This additional analysis is expected to provide further support of the new drug application (NDA) submission under the accelerated approval pathway, planned to be submitted by the end of 2025.

CNM-Au8 for the treatment of MS

In April, Clene presented new evidence of remyelination and neuronal repair with CNM-Au8 treatment at the American Academy of Neurology (AAN) Late-Breaking Science Session at the AAN 2025 Annual Meeting. The presentation, titled “Physiologic and Anatomical Evidence of Neuronal Repair and Remyelination from the Long-Term Open-Label Extension of the Phase 2 VISIONARY-MS Trial,” highlighted significant and clinically meaningful improvements in cognition and visual function, supported by corresponding objective biomarkers, including advanced MRI Diffusion Tensor Imaging (DTI) and multi-focal Visual Evoked Potential (mf-VEP) assessments which confirmed anatomical and physiological improvements, indicating remyelination and neuronal repair in the brains of MS patients treated with CNM-Au8 during the long-term extension of VISIONARY-MS.

The Company plans to hold an end-of-Phase 2 Type B meeting with the FDA in the third quarter of 2025. This meeting will review results from the Phase 2 VISIONARY-MS trial and discuss the planned Phase 3 study focusing on cognition improvement as an adjunct to standard-of-care MS therapies.

Second Quarter 2025 Financial Results

Clene’s cash and cash equivalents totaled $7.3 million as of June 30, 2025, compared to $12.2 million as of December 31, 2024. Clene expects that its resources as of June 30, 2025, together with $1.9 million raised in equity and a $1.5 million increase in its convertible debt facility subsequent to June 30, 2025, will be sufficient to fund its operations into the first quarter of 2026.

Research and development expenses were $3.5 million for the quarter ended June 30, 2025, compared to $4.2 million for the same period in 2024. The year-over-year decrease was primarily related to a decrease in personnel expenses due to cost saving initiatives and a decrease in manufacturing personnel due to the conclusion of various clinical programs, a decrease in stock-based compensation expense due to the timing of awards, as well as an increase in grant revenue, recorded as a reduction to research and development expense, due to an increase in enrollment and study operations in our NIH-sponsored EAP; partially offset by an increase in expenses related to our lead drug candidate, CNM-Au8, due to an increase in expenses related to our ALS clinical programs, including our NIH-sponsored EAP, and increased planning activities for the RESTORE-ALS Phase 3 clinical trial.

General and administrative expenses were $2.4 million for the quarter ended June 30, 2025, compared to $3.3 million for the same period in 2024. The year-over-year decrease was primarily related to a decrease in personnel expenses due to cost saving initiatives, a decrease in stock-based compensation expense due to the timing of awards, a decrease in legal fees primarily related to intellectual property and regulatory activities, and decreases in other expenses related to lobbying activities, travel, meals, office and other miscellaneous expenses; partially offset by an increase in finance and accounting fees, primarily due to an increase in audit and tax fees and fees from consultants, advisors, and other financial vendors.

Total other expense was $1.6 million for the quarter ended June 30, 2025, compared to total other income of $0.6 million for the same period in 2024. The year-over-year change was primarily related to non-cash losses recognized on the change in fair values of derivative liabilities separated from our senior secured convertible promissory notes, non-cash losses recognized on the change in fair values of common stock warrant liabilities, and a decrease in interest income primarily due to lower average balances of cash and cash equivalents and lower interest rates; partially offset by a decrease in interest expense primarily due to declining balances of notes payable following principal repayments.

Clene reported a net loss of $7.4 million, or $0.78 per share, for the quarter ended June 30, 2025, compared to a net loss of $6.8 million, or $1.06 per share, for the same period in 2024.
