Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Multi-center, randomized, double-blind, placebo-controlled, 6- month study in subjects with mild to moderate Dementia with Lewy Bodies.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The safety and efficacy of CT1812 at doses of 300 and 100mg will be evaluated over a 24 week double-blind treatment period in patient diagnosed with dementia with Lewy bodies.

Patients will be randomized 1:1:1 to placebo, 100mg CT1812 or 300mg CT1812. Oral CT1812 will be taken daily. Subjects meeting eligibility requirement and signing informed consent will be assessed by repeated psychometric/neurologic testing, safety procedures and PK and PD sample collection at defined intervals throughout the study. Plasma and CSF biomarkers will also be followed.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Men or women 50-85 years of age (inclusive), meeting criteria for probable Dementia with Lewy Bodies (DLB).
* MRI, or CT scan due to contraindication of MRI if approved by medical monitor) obtained during screening consistent with the clinical diagnosis of DLB and without findings of significant exclusionary abnormalities. An historical MRI (or CT scan), up to 1 year prior to screening, may be used if there is no history of intervening neurologic disease or clinical events (such as a stroke, head trauma etc.) and the subject is without clinical symptoms or signs suggestive of such intervening events.
* MMSE 18-27 inclusive

Exclusion Criteria

* Any neurological condition that may be contributing to cognitive impairment above and beyond those caused by the subject's DLB, including any co-morbidities detected by clinical assessment or MRI (or CT scan due to contraindication of MRI, if approved by medical monitor)
* Screening MRI (or historical MRI or CT scan due to contraindication of MRI if approved by medical monitor) or historical MRI/CT scan, if applicable. of the brain indicative of significant abnormality, including, but not limited to, prior hemorrhage or infarct \> 1 cm3, \>3 lacunar infarcts, cerebral contusion, encephalomalacia, aneurysm, vascular malformation, subdural hematoma, hydrocephalus, space-occupying lesion (e.g. abscess or brain tumor such as meningioma). If a small incidental meningioma is observed, the medical monitor may be contacted to discuss eligibility.
* Clinical, laboratory findings or medical history consistent with:

1. Other primary degenerative dementia (fronto-temporal dementia, Huntington's disease, Creutzfeldt-Jakob Disease, Down syndrome, etc.).
2. Other neurodegenerative condition (amyotrophic lateral sclerosis, etc.).
3. Seizure disorder.
4. Other infectious, metabolic or systemic diseases affecting the central nervous system (syphilis, present hypothyroidism, present vitamin B12 or folate deficiency, other laboratory values etc.).
* Any major psychiatric diagnosis, including schizophrenia, bipolar disorder, and current major depressive disorder as per Diagnostic and Statistical Manual of Mental Disorders Fifth Edition
* Clinically significant, advanced or unstable disease that may interfere with outcome evaluations.
