Descriptive Information
Brief Title  ICMJE Young Plasma Transfusions for Progressive Supranuclear Palsy
Official Title  ICMJE A 6 Month, Open-Label, Pilot Futility Clinical Trial of Monthly Young Healthy Male Donor Plasma Transfusions for Progressive Supranuclear Palsy
Brief Summary This is a phase 1, multi-center, open-label study of the safety, tolerability, pharmacodynamics, and preliminary efficacy of young (<30 years of age) healthy male donor plasma transfusions in patients with PSP. Up to 10 subjects will receive once monthly 4-unit transfusions of young healthy male donor plasma for 6 months.
Detailed Description

This is a phase 1, multi-center, open-label study of the safety, tolerability, pharmacodynamics, and preliminary efficacy of young (<30 years of age) healthy male donor plasma transfusions in patients with PSP. Up to 10 subjects will receive once monthly 4-unit transfusions of young healthy male donor plasma for 6 months.

If ≥3 subjects experience drug limiting toxicity (DLT), as defined in Section 7.19, the study will be terminated. Any subject that experiences a DLT will be discontinued from further treatment with the study drug.

An interim futility analysis will be performed after five subjects have completed 6 months of study drug treatment. If the criteria listed in Section 9.3 of this protocol are met, an additional 5 subjects will be enrolled in the trial. If not, the trial will be terminated.
