Senicapoc in Alzheimer's Disease

Status Recruiting

Clinical Trial Summary

Development of novel disease-modifying therapies for Alzheimer's disease (AD) remains of paramount importance. This study will be a Phase II randomized clinical trial testing Senicapoc in patients with mild or prodromal AD. This will be a small Proof of Mechanism study to prove biological activity and target engagement in humans with early AD. The investigators will study up to 55 patients over 52 weeks, with primary outcomes being Alzheimer's Disease Assessment Scale Cognitive Subscale (ADAS-Cog) scores and blood and cerebrospinal fluid (CSF) markers of neuroinflammation. This pilot study will provide an estimate of treatment effect size on cognitive trajectory, daily function, and brain atrophy.

Clinical Trial Description

The investigators will study up to 55 patients (8:3 active treatment with 10 mg/day maintenance dose: placebo) over 52 weeks in either the Sacramento or East Bay locations the University of California Davis Alzheimer's Disease Research Center (ADRC), with cognitive outcomes, blood, and CSF markers of neuroinflammation. This pilot study will provide an estimate of treatment effect size on cognitive trajectory, daily function, and brain atrophy. The trial will last 1 year (52 weeks on 10 mg/day of active drug or placebo) with primary efficacy measures at baseline, week 26, and week 52. Additional safety monitoring visits will occur at weeks 4, 12, and 36 including physical exams, measurement of blood pressure, vital signs, safety labs, electrocardiogram recordings, collection of Adverse Events and Concomitant Medications. The study will culminate with a visit at 78 weeks (26 weeks after last dose, allowing full wash-out from the central nervous system (CNS)) to test if the previously treated and untreated groups show any differences, as would be expected if Senicapoc treatment for 1 year was disease-modifying. All participants will be required to participate in either the CSF Sub-study or the Amyloid Positron Emission Tomography (PET) Sub-study. All participants will be required to participate in the Cognitive Event Related Potential (ERP) Sub-study. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
