  • Background dementia therapy:
  • Not currently receiving cholinesterase inhibitor therapy. If the patient received such therapy previously, that therapy must have been discontinued at least 3 months prior to randomization.
  • Receiving cholinesterase inhibitor therapy alone. If the patient is currently receiving cholinesterase inhibitor therapy, the patient must have received such therapy for greater than 3 months and on a stable dose for at least 6 weeks at the time of randomization. Except for reducing the dose for tolerability reasons, the dose of cholinesterase inhibitor may not be modified during the study.
  • Memantine therapy is allowed, if it had been started at least 3 months prior to randomization and the patient is also receiving cholinesterase inhibitor therapy. If the patient has never been on cholinesterase inhibitor therapy (naïve), then memantine monotherapy is allowed.
  • Normal or corrected eyesight and auditory abilities, sufficient to perform all aspects of the cognitive and functional assessments.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • NeflamapimodDrug

    Also called VX-745

    Neflamapimod is a highly specific inhibitor of the intra-cellular enzyme mitogen-activated protein kinase14 (p38α) provided in 40mg capsules

  • PlaceboDrug

    Placebo is a capsule that looks just like neflamapimod but without the active ingredients

Receives: Drug: Neflamapimod

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Clinical Dementia Rating Scale - Sum of Boxes (CDR-SB) in Neflamapimod-treated Participants Compared to Placebo Recipients (Blinded Treatment Period)

    Evaluate the efficacy of neflamapimod, compared to placebo, as a treatment for DLB, as assessed by the CDR-SB scale.

    CDR-SB scores range from 0 to 18 with a higher score indicating worsening of cognitive impairment.

    Measured: 16 weeks

Secondary outcomes (3)
  1. Change in Timed Up and Go Test (TUG) in Neflamapimod-treated Participants Compared to Placebo Recipients (Blinded Treatment Period)

    Evaluate if neflamapimod improves motor function in participants with DLB, compared to placebo, as assessed by the TUG test.

    TUG scores typically range from 6 to 20 seconds with a higher score indicating worse mobility. A score of >15 indicates an increased risk of falls.

    Measured: 16 weeks

  2. Change in the Composite Score of the Neuropsychological Test Battery (NTB), Including Tests of Attention, Executive Function, and Visual Learning in Neflamapimod-treated Participants Compared to Placebo Recipients (Blinded Treatment Period)

    Evaluate if neflamapimod improves cognition, compared to placebo, as assessed by a DLB-specific NTB in participants with DLB. NTB includes Cogstate Detection test (DET), Cogstate Identification test (IDN), Cogstate One Card Learning test (OCL), Cogstate One Back test (ONB).

    Each score on the individual tests is converted to a z-score, and then a total z-score for the composite is calculated, in which each test is weighted equally. As the analysis is based on z-scores, there is no minimum or maximum value. A z-score of 0 is equal to the mean with negative numbers indicating values lower than the mean and positive values higher. A positive change in z-score indicates an improvement in cognition and a negative change in z-score indicates a worsening in cognition.

    Measured: 16 weeks

  3. Alzheimer's Disease Cooperative Study - Clinical Global Impression of Change (ADCS-GCIC) Score at Week 16 in Neflamapimod-treated Participants Compared to Placebo Recipients (Blinded Treatment Period)

    Evaluate if neflamapimod improves global (cognition, function and behavior) disease status evaluated by a clinician with caregiver input, compared to placebo, in participants with DLB, as assessed ADCS-CGIC score.

    ADCS-CGIC scores range from 1 to 7, where 1 = marked improvement, 2= moderate improvement, 3 = minimal improvement, 4 = no change, 5 = minimal worsening, 6 = moderate worsening, and 7 = marked worsening.

    Measured: 16 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Neflamapimod in people with Dementia With Lewy Bodies, run by EIP Pharma Inc at 40 sites in 3 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 14 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 40 sites in United States, United Kingdom, Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 3 Sep 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Clinical Dementia Rating Scale - Sum of Boxes (CDR-SB) in Neflamapimod-treated Participants Compared to Placebo Recipients (Blinded Treatment Period) (time frame: 16 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05869669, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Sep 2026; AzTrials last refreshed its copy on 8 Nov 2026.
