Recruiting PHASE2 Alzheimer Disease

New treatment option for Alzheimer Disease

Official title Biomarker-based Trial of NPC-1 for Alzheimer's Pathology

ClinicalTrials.gov ID: NCT07236190

What this study is testing

What is natural product combination-1 (NPC1)?

natural product combination-1 (NPC1) is an investigational medicine, being studied as a potential treatment for alzheimer disease.

Also referred to as parthenolide, ipriflavone.

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
This early phase, open label, single arm clinical trial will determine the intraindividual safety, tolerability and effects of NPC1 (parthenolide and ipriflavone) on blood-based biomarkers of Alzheimer's disease (AD) pathology among adults with subjective cognitive decline, mild cognitive impairment, or Alzheimer's disease and objective indicators of seeding AD pathology
