Full Study Name

A Phase II, Randomized, Double-Blind, Placebo-Controlled Multiple Dose Study to Assess Efficacy, Safety, Tolerability, and Pharmacokinetics of ABBV-8E12 in Progressive Supranuclear Palsy (IRB no. 47591)


This study focuses on patients with progressive supranuclear palsy (PSP) who are over 40 years old. The purpose of the study is to evaluate an investigational drug called ABBV-8E12 and learn whether it could help slow down a disease called progressive supranuclear palsy (PSP). The study will also assess various doses of the drug and confirm its safety in patients with PSP.

Researchers aim to determine the effects that treatment with ABBV-8E12 will have on blood chemistry, cerebrospinal fluid, and clinical and biological markers of PSP. Information from brain magnetic resonance imaging (MRI) scans will also be collected to evaluate whether ABBV-8E12 appears to have an effect on the PSP disease process. Participants will be monitored carefully for side effects.
