Insights
CervoMed's extension phase results for neflamapimod represent a significant clinical breakthrough in DLB treatment. The data demonstrates statistically significant improvement on the Clinical Dementia Rating Sum of Boxes (CDR-SB) with p<0.001 versus control and p=0.003 versus placebo - exceeding the clinically meaningful threshold of 0.5 points. Most impressively, there was a 40% relative reduction in patients experiencing meaningful clinical deterioration.
The pharmacological challenge identified in the initial phase has been resolved through improved capsule formulation. The previous lack of efficacy signal was likely due to subtherapeutic plasma concentrations, not drug failure. Now achieving target concentrations, neflamapimod shows consistent benefits across multiple endpoints, including CGIC, cognitive fluctuations, and working memory.
What's particularly compelling is the reduced fall incidence (4% vs 15.2%), addressing a major complication in DLB. These results validate neflamapimod's mechanism targeting cholinergic neuron function in the basal forebrain - a critical pathway in DLB pathophysiology.
The consistency across endpoints and stronger effect in patients without Alzheimer's co-pathology (ptau181 <2.2 pg/mL) indicates precise targeting of DLB-specific processes. With minimal therapeutic options currently available for DLB, these results position neflamapimod as potentially the first disease-modifying treatment, representing a substantial advancement over current symptomatic approaches.
CervoMed's advancement of neflamapimod demonstrates exceptional strategic execution in overcoming a formulation challenge that could have derailed the program. Identifying the pharmacokinetic issue with the original capsules and implementing a solution that achieved target plasma concentrations allowed them to salvage what appears to be a promising asset.
The Extension phase results are particularly robust from a regulatory perspective. The dual demonstrations of efficacy - both versus the Old Capsules control group and versus the Initial phase placebo - create compelling evidence packages. The magnitude of effect on CDR-SB (0.73 point improvement) exceeds the 0.5-point threshold considered clinically meaningful in dementia trials.
Most notably, their stratification by plasma ptau181 biomarker shows enhanced efficacy in "pure" DLB without Alzheimer's co-pathology - a 62% reduction in clinical deterioration in this subgroup. This indicates a potential precision medicine approach that could streamline future pivotal trials and enhance regulatory success probability.
The comprehensive endpoint battery demonstrating consistent benefits across cognitive, functional, and neuropsychiatric measures creates multiple pathways to regulatory success. With these results, CervoMed appears well-positioned to design a Phase 3 program with high probability of technical and regulatory success in a condition with significant unmet need and minimal competition.

The results demonstrate proof-of-concept for neflamapimod as a treatment for dementia with Lewy bodies (DLB)
BOSTON, April 02, 2025 (GLOBE NEWSWIRE) -- 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 Study1
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:
- Improvement on primary outcome measures, change in CDR-SB, with the New Capsules both vs. Old Capsules (p<0.001) during first 16 weeks of the Extension phase and vs. placebo (p=0.003) utilizing all data in the study through to week 32 (includes Initial phase and first 16 weeks of the Extension phase).1
- The magnitude of the effect on the CDR-SB was for all participants a mean improvement of 0.73 points with the New Capsules compared to the Old Capsules, and a mean 0.81 points in participants whose screening plasma ptau181 was less than 2.2 pg/mL (indicating absence of Alzheimer’s disease (AD) co-pathology); both exceeding the 0.5-point treatment group difference considered to be clinically meaningful (Tarawneh and Pankratz, Alzheimers Res Ther 2024;16:3).
- The percentage of participants who had clinically meaningfully worsening (i.e. increased greater than or equal to 1.5 points on the CDR-SB) during the first 16 weeks of the Extension phase was
40% lower on a relative basis (26.8% vs.45.1% ) in New Capsule recipients compared to Old Capsule recipients; and62% lower (17.7% vs.45.8% ) in participants whose screening plasma ptau181 was less than 2.2 pg/mL. - Improvement on Alzheimer’s Disease Cooperative Study (ADCS)-CGIC in participants administered New Capsules both in comparison to Old Capsules (p=0.035) during the Extension phase and in a within-participant comparison to placebo treatment during the Initial phase (p=0.039). The improvement compared to placebo in the within-participant analysis was not seen with the Old Capsules.
- Based on evaluation of
95% confidence intervals, improvement with New Capsules versus Old Capsules seen on Dementia Cognitive Fluctuation Scale and International Shopping List Test-Recognition (measuring working memory); and positive trends were seen on 12-item Neuropsychiatric Inventory (NPI-12), Timed Up and Go (TUG) and Unified Parkinson’s Disease Rating Scale Part III (Motor). These new analyses support the positive findings previously reported for the CDR-SB and the ADCS-CGIC.
Old and New Capsules have similar overall safety and tolerability profile:
- Both Old and New Capsules demonstrated comparable tolerability profiles and no new safety signals were identified during the Extension phase.
- Lower incidence of falls with the New Capsules (
4% vs.15.2% with Old Capsules during the Extension phase, p=0.025, and19.7% with placebo in the Initial phase, p=0.007) in participants with screening ptau181 < 2.2 pg/mL.
