Mild Cognitive Impairment study: Senicapoc
Official title Senicapoc in Alzheimer's Disease
ClinicalTrials.gov ID: NCT04804241
What this study is testing
What is Senicapoc?
an investigational oral tablet being studied as a potential treatment for mild cognitive impairment/early Alzheimer's disease is designed to block the KCa3.1 potassium channel, which may reduce neuroinflammation
Also referred to as TRAM-34.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The study aims to see if Senicapoc reaches its target in the brain and changes markers of inflammation, cognition, daily function, and brain shrinkage in early Alzheimer's.
- Who it's for
- Adults diagnosed with mild cognitive impairment or early (prodromal) Alzheimer’s disease.
- What's involved
- Participants will take the study medication, undergo regular clinic visits, and have blood draws, spinal fluid (lumbar puncture) samples, and cognitive testing.
- Time commitment
- The trial lasts about 52 weeks with scheduled visits and tests throughout the year.
- Phase 2: a mid-size study of how well it works
- Time commitment: about 52 weeks
- You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance.

- History of chronic psychiatric illness (e.g. schizophrenia), any episode of major depression within last 2 years, or current Geriatric Depression Scale (GDS) \> 6, any recent suicide attempts or suicidal ideation.
- History of a serious infectious disease affecting the brain (including neurosyphilis, meningitis, or encephalitis), head trauma resulting in any persistent cognitive deficit
- History of alcohol or drug abuse/dependence within the past 5 years
- Known allergy to chemically related compounds (e.g. clotrimazole)
