Clene Reports Significantly Decreased Mortality in RESCUE-ALS Long-Term Open Label Extension Trial

July 14, 2022
  • As of the July 5, 2022, data cutoff, early CNM-Au8® treatment resulted in a significant survival benefit (5 CNM-Au8 deaths vs. 14 placebo deaths, HR=0.301, p=0.0143)
  • CNM-Au8 treatment was well-tolerated, and there were no significant safety findings reported during this open-label trial
  • Top-line results from HEALEY ALS Platform Trial are expected in current quarter

SALT LAKE CITY, July 14, 2022 (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 disease, today reported significantly improved survival in ALS patients initially treated with CNM-Au8 compared to initially randomized placebo treated participants during the long-term open-label extension of its RESCUE-ALS trial.

“We are very pleased to see these results and the apparent survival benefit that our investigational drug, CNM-Au8, appears to provide to people living with ALS,” said Rob Etherington, President and CEO of Clene. “At this point, we are awaiting top-line data from the HEALEY ALS Platform Trial, which focuses on endpoints measuring patient function, survival and breathing over a six-month period in a much larger cohort. Clene expects to announce these results this quarter. Based on the larger number of patients treated in the HEALEY trial and the higher dose of CNM-Au8 being tested, we are optimistic that we will be able to adequately characterize the effects of our drug on this devastating disease.”

Study participants in RESCUE-ALS were randomized 1:1 to receive 30 mg of CNM-Au8 or placebo daily for 36 weeks during the double-blind portion of the study, followed by an open-label period that extended treatment up to 130 weeks from randomization. The trial enrolled 45 participants (n=23 on active treatment, and n=22 receiving placebo), and survival was compared by treatment group from randomization through the latest vital status observation with a cut-off as of July 5, 2022, for this interim analysis. Participants in the placebo-treated group, who received either no treatment or a nine-month delay in treatment initiation with CNM-Au8, were compared to participants treated daily with CNM-Au8 from randomization.

Survival data were obtained for 43 of 45 study participants, and one participant in each group was lost to follow-up. There were five deaths in the group originally randomized to CNM-Au8 and 14 deaths in the group originally randomized to receive placebo. Median survival from randomization for the CNM-Au8 group was undefined due to insufficient mortality events, and median survival for the placebo group was 23.1 months. Unadjusted Kaplan-Meier survival analyses demonstrated a significant survival benefit with participants initially randomized to CNM-Au8 treatment versus those initially randomized to placebo, resulting in a 70% decreased risk of death, log-rank hazard ratio = 0.301 (95% CI: 0.122 to 0.742, p = 0.0143). Sensitivity analyses substituting death in place of lost to follow-up censoring resulted in concordant findings (Hazard Ratio: 0.338, 95% CI: 0.143 to 0.797, p = 0.0182). The treatment was well-tolerated, and there were no significant safety findings reported during the long-term open label trial period. These data will be reported at an upcoming scientific congress.
