SALT LAKE CITY, March 11, 2022 -- 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, today reported its full year 2021 operating and financial results, as well as an overview of fourth quarter 2021 and recent operating highlights.

“We exited 2021 with significant momentum, having made substantial clinical advancement across our portfolio of first-in-class nanotherapeutics,” said Rob Etherington, President and CEO of Clene. “This progress now has Clene positioned to achieve multiple clinical milestones in 2022, highlighted by the upcoming results from the HEALEY ALS Platform Trial. Positive results for CNM-Au8® in this study would be transformative for Clene, and more importantly, for people living with ALS.”

Fourth Quarter 2021 and Recent Operating Highlights

CNM-Au8®, a gold nanocrystal suspension, for the treatment of amyotrophic lateral sclerosis (ALS)

•Enrollment in the HEALEY ALS Platform Trial, led by the Sean M. Healey & AMG Center for ALS at Massachusetts General Hospital, was completed in November 2021, and top-line data are expected in the second half of this year.

•Top-line results from the RESCUE-ALS Phase 2 clinical trial were reported in November 2021. Results demonstrated clinically meaningful benefits in people with early ALS, including:

oResults showed the slowing of disease progression and improvements to patients’ quality of life. In addition, RESCUE-ALS demonstrated evidence for a potential long-term survival benefit from CNM-Au8®.

oData from RESCUE-ALS were presented in the fourth quarter of 2021 at the 4th Annual ALS ONE Research Symposium and at a late-breaking session at the 32nd International Symposium on ALS/MND.

•Additional data including the significant survival benefit from the RESCUE-ALS open label extension will be presented at the upcoming Muscular Dystrophy Association Clinical & Scientific Conference this month and at a late breaker session at the upcoming American Academy of Neurology Annual Meeting in April.

•Clene continues to support expanded access programs, providing CNM-Au8® treatment at four clinical sites to more than 50 participants with ALS.

CNM-Au8® for the treatment of multiple sclerosis (MS)

•Clene has initiated a second cohort of the more severe non-active, progressive MS population in the REPAIR-MS Phase 2 clinical trial to confirm the robust target engagement demonstrated in the first cohort of relapsing MS patients in this trial.

•The VISIONARY-MS Phase 2 clinical trial will conclude early due to pandemic-related enrollment challenges. Clene will utilize the available data collected from up to 48 weeks of clinical visits to better understand the efficacy and safety profile of CNM-Au8® and to inform further clinical development in MS.

oUnblinded VISIONARY-MS data are targeted for the second half of 2022.

oUpdated blinded interim data from VISIONARY-MS and results from REPAIR-MS Phase 2 trials were presented at the Americas Committee for Treatment and Research in Multiple Sclerosis Forum 2022 in February 2022.

CNM-ZnAg™ for the treatment of COVID-19

•The CNM-ZnAg COVID Phase 2 clinical trial achieved full enrollment in acutely symptomatic, non-hospitalized COVID-19 patients in Brazil. Top-line results are expected mid-year 2022.

Corporate Updates

•Morgan Brown was appointed Chief Financial Officer (CFO) effective February 1, 2022. Mr. Brown’s extensive experience in executive finance roles includes four publicly traded life science companies, three as CFO, and experience as the CFO of a privately held clinical research organization.

•Two key patents were granted and validated in Europe that protect Clene’s breakthrough processes, devices and methods for treating certain disease indications for its nanotherapeutic drugs. Clene was also granted a patent from the U.S. Patent and Trademark Office for CNM-Au8 for the treatment of MS.

•Clene announced a $1 million grant award from the Maryland Department of Housing and Community Development in support of the redevelopment of a 72,000 ft2 manufacturing facility in Elkton, Maryland, in anticipation of product commercialization.

Full Year 2021 Financial Results

Clene’s cash and restricted cash totaled $50.3 million as of December 31, 2021, compared to $59.3 million as of December 31, 2020. Clene expects that its resources as of December 31, 2021, will be sufficient to fund its operations into the second quarter of 2023.

Research and development expenses were $28.4 million for the year ended December 31, 2021, compared to $15.2 million for the same period in 2020. The year-over-year increase was primarily related to the development of CNM-Au8, rent expense for the newly-leased facility in Elkton, Maryland, and personnel and stock-based compensation due to increased headcount, partially offset by decreased manufacturing and materials expense.

General and administrative expenses were $22.0 million for the year ended December 31, 2021, compared to $5.2 million for the same period in 2020. The year-over-year increase was primarily attributable to costs related to being a public company and fees for professional services, technology services, and pre-commercialization activities for CNM-Au8, and personnel and stock-based compensation due to increased headcount.

Clene reported a net loss of $9.7 million, or $0.16 per share, for the year ended December 31, 2021, compared to a net loss of $19.3 million, or $1.10 per share, for the same period in 2020. Included in net loss for the year ended December 31, 2021, was an unrealized gain from the change in fair value of contingent earn-out liabilities of $37.5 million, compared to $14.1 million in the prior year period.
