Effects of EVP-0962 on Amyloid Levels in Cerebrospinal Fluid

Effects of EVP-0962 on Amyloid Levels in Cerebrospinal Fluid

Overall Status: 
Brief Description: 

This Phase II study is designed to determine the safety, tolerability, pharmacokinetics, and effects of EVP-0962 on levels of amyloid in the cerebrospinal fluid of healthy people and those with mild cognitive impairment (MCI)  or early Alzheimer's disease.

Inclusion Criteria: 

    Healthy Participants

    • Age 45 to 65

    • QTc values greater than 450 ms
    • Positive drug screening test results
    • Pregnant, nursing, or unwilling to use birth control measures during study
    • C-SSRS suicidal ideation score of 4 or 5
    • Unwilling to abstain from vigorous exercise

Detailed Description: 

This study of the experimental drug EVP-0962 will be conducted in two parts. The first part will evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of escalating EVP-0962 doses (10 mg, 50 mg, 100 mg, and 200 mg) for 14 days in healthy subjects. The second part will evaluate the same outcomes following once-daily administration for 14 days in participants with MCI or early Alzheimer's disease. EVP-0962 modulates an enzyme, gamma secretase, involved in the processing of amyloid and its toxic amyloid-beta 1-42 peptide, a key component of amyloid plaques in the brains of people with Alzheimer's disease.
