CervoMed Announces Key Takeaways from Oral Presentations at the 17th Clinical Trials on Alzheimer's Disease Conference (CTAD)

CervoMed Inc. (NASDAQ: CRVO), a clinical-stage company focused on developing treatments for age-related neurologic disorders, today announced key takeaways from two oral presentations characterizing the potential of neflamapimod as a treatment for patients with dementia with Lewy bodies (DLB) that were presented at the Clinical Trials on Alzheimer’s Disease Conference (CTAD) on November 1, 2024.

“DLB is a rapidly debilitating condition affecting over 1.4 million patients in the U.S. and EU that has no approved treatment,” said John Alam, MD, Chief Executive Officer of CervoMed. “As we approach the December topline results for our innovative proof-of-concept RewinD-LB Phase 2b clinical trial of neflamapimod, we are excited to share additional results on the effect of neflamapimod treatment on an important biomarker of DLB neurodegenerative disease activity, as well as the baseline characteristics of the patients enrolled into the Phase 2b study. Taken together, we believe the findings further increase the probability of success of the clinical trial”

Dr. Alam continued, “For both Alzheimer’s disease and DLB, the utilization of imaging and blood testing to exclude patients with high levels of tau pathology has emerged as a powerful tool to focus clinical trials on patients who have the least amounts of fixed, irreversible neurodegeneration, thereby increasing the magnitude of the clinical effect and probability of success. In the first presentation, through demonstrating significant beneficial effects on a robust blood biomarker of DLB disease activity and correlating that effect to the clinical outcome and underlying pathology, we show that neflamapimod in our Phase 2a clinical study reduced neurodegenerative disease activity in the basal forebrain cholinergic system and its clinical activity is mediated by that effect. In the second presentation we show that the clinical profile of the patients enrolled into RewinD-LB has substantial clinical disease burden and is similar to that in the patients without biomarker evidence of tau pathology group in the Phase 2a study, the group that showed the highest magnitude treatment response. We believe successfully enrolling a DLB patient population that has substantial clinical disease burden, while not have biomarker evidence of tau pathology, and with it a higher expected magnitude treatment effect than if the study had enrolled patients without screening for level of tau pathology, further increases our confidence in the outcome of the RewinD-LB trial.”

The presentations are accessible on the “Presentations and Publications” section of the CervoMed website.

Key takeaways from the presentations: 

We have demonstrated a treatment effect on a robust biomarker of neurogenerative disease activity in DLB. Plasma GFAP is highly correlated to cognitive decline as well as to neuronal and neurofibrillary tangles, a pathologic measure of neurodegenerative disease activity. Plasma GFAP is also the first biomarker that is elevated in the evolution of DLB, which combined with the treatment effect of cholinergic directed therapy such as neflamapimod, indicates that elevated plasma GFAP in DLB patients that do not have biomarker evidence of tau pathology reflects neurodegenerative disease activity in the basal forebrain cholinergic system. Accordingly, the treatment effect of neflamapimod on plasma GFAP in DLB patient with low tau pathology in the Phase 2a clinical study demonstrates that neflamapimod reduces neurodegenerative disease activity in the basal forebrain cholinergic system and its clinical activity is mediated by that effect.  

We are targeting a patient population that is most likely to respond to neflamapimod in the RewinD-LB trial. Compared to Early AD patients, DLB patients without tau pathology are afflicted by higher clinical disease burden, as measured by the Clinical Dementia Rating Sum of Boxes (CDR-SB), due to having disease in the basal forebrain cholinergic system. Combined with the Phase 2a data demonstrating the high level of treatment effect in these patients, DLB patients who do not have biomarker evidence of tau pathology represent an ideal patient population for evaluating a cholinergic-directed therapy such as neflamapimod.

By exclusively enrolling patients without biomarker evidence of tau pathology the sample size of RewinD-LB provides high statistical power to detect a statistically significant and clinically meaningful difference between neflamapimod and placebo. The sample size for RewinD-LB of 80 per patients per arm was originally chosen to have sufficient statistical power to detect the expected treatment effect in a population including patients both with and without biomarker evidence of tau pathology. By including only patients without biomarker evidence of tau pathology, while maintaining the original sample size, the study has greater than 95%, approaching 100% statistical power for meeting its primary endpoint, change in CDR-SB in neflamapimod-treated patients compared to placebo.

About CervoMed

CervoMed Inc. (the “Company”) is a clinical-stage company focused on developing treatments for age-related neurologic disorders. The Company is currently developing neflamapimod, an investigational, orally administered small molecule brain penetrant that inhibits p38 mitogen-activated protein kinase alpha. Neflamapimod has the potential to treat synaptic dysfunction, the reversible aspect of the underlying neurodegenerative processes that causes disease in DLB and certain other major neurological disorders. Neflamapimod is currently being evaluated in a Phase 2b study in patients with early-stage DLB.
