Summary

This is a phase 1, multi-center, double-blind, placebo-controlled, multiple dose escalation study with NIO752 in progressive supranuclear palsy (PSP) participants.

Description

This is a phase 1, multi-center, double-blind, placebo-controlled, multiple dose escalation study with NIO752 in progressive supranuclear palsy (PSP) participants.

Approximately 64 PSP participants in 6 cohorts will be randomized to receive NIO752 or placebo in a ratio of 3:1. Intrathecal ( IT ) injections of NIO752 or placebo will be given 4 times over 3 months. All participants will remain in this study for an additional 9 month follow-up period with 6 scheduled visits.

Cohorts will be enrolled sequentially.

Safety assessments will include physical and neurological examinations, ECGs, vital signs, standard clinical laboratory evaluations (hematology, blood chemistry, and urinalysis), CSF laboratory test, adverse event, and serious adverse event monitoring.

knowledgeable of the participant's ongoing condition during the study to
provide study related information to study site when required both in person
and via a phone Reside in a proximity to the study site to allow a timely
unscheduled visit if necessary (ideally less than 2 hours) Able to undergo
lumbar puncture (LP), CSF draws and blood draws
If the participant is receiving levodopa/carbidopa, levodopa/benserazide, a dopamine agonist, catechol-o-methyltransferase (COMT) inhibitor, rasagiline, CoQ10 or other Parkinson's medications, acetylcholinesterase inhibitors, antipsychotics, memantine, or other non-tau modifying Alzheimer's medication the dose must have been stable for at least 30 days prior to the screening visit and must remain stable for the duration of the study.

Use of lithium, methylene blue or other putative disease modifying drugs for PSP within 30 days of screening
Any previous use of experimental therapy within 30 days or 5 half-lives prior to Day 1, whichever is greater
