Investigators to Present Clinical Trial Results Showing Neflamapimod Slows Clinical Progression in Dementia with Lewy Bodies in Oral Presentation at AD/PD™ 2025

During the first 16 weeks of the Extension phase of the RewinD-LB clinical study neflamapimod slowed clinical progression compared to controls, as assessed by Clinical Dementia Rating Sum of Boxes (CDR-SB) and Clinical Global Impression of Change (CGIC)

Neflamapimod was associated with a reduced incidence of falls in the Extension phase of the study and new data to be presented at AD/PD™ 2025 demonstrates improvements on endpoints measuring cognitive fluctuations and working memory

The results demonstrate proof-of-concept for neflamapimod as a treatment for dementia with Lewy bodies (DLB)

Boston – April 2, 2025 – CervoMed Inc. (NASDAQ: CRVO), a clinical stage company focused on developing treatments for age-related neurologic disorders (CervoMed or the Company), today announced that investigators plan to present results, including new results, from the Extension phase of the Phase 2b RewinD-LB study that show neflamapimod demonstrated a clinically meaningful effect on slowing clinical progression in patients with DLB in an oral presentation during the 19th International Conference on Alzheimer’s and Parkinson’s Disease and Related Neurologic Disorders (AP/PD™) on Saturday, April 5, 2025.

“The RewinD-LB Extension phase results for neflamapimod are highly encouraging. We are seeing a clear and meaningful effect on clinical worsening over time in patients with DLB, as assessed by CDR-SB and CGIC, which is further supported by positive data across several additional clinical endpoints,” stated Stephen Gomperts, MD, PhD, Associate Professor of Neurology at Harvard Medical School, Director, Lewy Body Dementia Unit at the Massachusetts General Hospital and site Principal Investigator for the RewinD-LB study. “Importantly, these results validate and replicate prior clinical trial results and are consistent with the scientific hypothesis that neflamapimod can provide clinical benefit by arresting the loss of cholinergic neuron function in the basal forebrain.”

“The presentation of the Extension phase data at AD/PD™ 2025 is an opportunity to share our findings and engage deeply with the DLB medical community as we plan for pivotal development and work to bring neflamapimod to patients as rapidly as possible,” said John Alam, MD, Co-Principal Investigator of the RewinD-LB study and CEO of CervoMed. “The positive findings across the primary outcome measure and multiple additional clinically important endpoints evaluated in the first 16 weeks of the Extension phase strengthen our belief that neflamapimod has the potential to be a transformative therapy for patients with DLB.”

16-Week Results from the Extension Phase of the Phase 2b RewinD-LB Study

Overview

Of the 159 participants randomized in the initial 16-week double-blind, placebo-controlled phase (Initial phase) of the study, 152 completed the Initial phase and 149 entered the extension phase (Extension phase), during which all participants received neflamapimod. As previously announced, during the Extension phase, 55 participants continued to receive the same batch of capsules (Old Capsules) utilized in the Initial phase of the study, while 94 participants received a new batch of capsules (New Capsules) for at least 8 weeks during the Extension phase, approximately half of which received only the New Capsules. In the Initial phase of the study, there were no discernible differences in clinical outcome between the neflamapimod (administered in Old Capsules) and placebo, which was hypothesized to be the result of sub-therapeutic plasma drug concentrations observed with the Old Capsules.

The New Capsules achieved target plasma drug concentrations, which has allowed CervoMed and clinical investigators to compare clinical outcomes between participants receiving the New Capsules (representing an active drug arm) and the Old Capsules (representing a control arm), as well as analyses that compared New Capsules administered during the Extension phase to placebo during the Initial phase of the study. For the comparison to placebo, the Old Capsules served as an important negative control. Participants and site personnel were blinded as to whether New or Old Capsules were being dispensed during the first 16 weeks of the Extension.

Positive effects seen with the New Capsules of neflamapimod compared to controls on multiple clinical endpoints:
