Phase 1 / Phase 2: testing ARO-MAPT-SC for Alzheimer Disease

Trial to measure the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of ARO-MAPT-SC compared to dummy treatment (placebo) in adult healthy volunteers and in participants with early Alzheimer's disease (AD), defined as mild cognitive impairment due to AD and mild AD dementia, as well as primary tauopathies, including microtubule associated protein tau -related frontotemporal dementia (MAPT-FTD) and progressive supranuclear palsy- Richardson syndrome (PSP-RS).

Official registry: https://clinicaltrials.gov/study/NCT07221344 · Arrowhead Pharmaceuticals · enrollment listed as 160

What this phase means

Phase 2: researchers already know a roughly safe dose (from phase 1). This stage asks whether the treatment actually helps the condition, and watches side effects more closely.

Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.

What the registry says happens

If you join, the listed intervention(s) are ARO-MAPT-SC, or Placebo. The registry lists allocation as randomized. Trial to measure the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of ARO-MAPT-SC compared to dummy treatment (placebo) in adult healthy volunteers and in participants with early Alzheimer's disease (AD), defined as mild cognitive impairment due to AD and mild AD dementia, as well as primary tauopathies, including microtubule associated protein tau -related frontotemporal dementia (MAPT-FTD) and progressive supranuclear palsy- Richardson syndrome (PSP-RS).

They plan to enroll about 160 people at 4 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
