Clinical Trial: Young Plasma Transfusions for Progressive Supranuclear Palsy

Study Status: Recruiting
Recruit Status: Recruiting
Study Type: Interventional

Official Title: 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 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.

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.

Current Primary Outcome: Number of patients experiencing drug limiting toxicity (DLT) [ Time Frame: 6 months ]

To determine the safety and tolerability of once monthly 4-unit transfusions of young (<30 years of age) healthy male donor plasma for 6 months in patients with progressive supranuclear palsy (PSP). Number of patients experiencing drug limiting toxicity (DLT), defined as: 1) any Grade 3 or higher adverse event (AE) per National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) for which there is reasonable possibility that salsalate caused the event, 2) any Grade 2 AE in the CTCAE system organ class of nervous system disorders that is considered clinically significant and for which there is reasonable possibility that salsalate caused the event, or 3) any Grade 2 or higher treatment-related adverse events during administration that do not resolve promptly with supportive treatment


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Changes in motor function as measured by Progressive Supranuclear Palsy Rating Scale (PSPRS) [ Time Frame: 6 months ]
    Motor function as measured by Progressive Supranuclear Palsy Rating Scale (PSPRS) comprising 28 items in six categories: daily activities (by history), behavior, bulbar, ocular motor, limb motor and gait/midline The available total score ranges from 0 to 100; lower scores reflect better outcome.
  • Changes in cognition as measured by Progressive Supranuclear Palsy Rating Scale (PSPRS) [ Time Frame: 6 months ]
    Cognitive function as measured by Progressive Supranuclear Palsy Rating Scale (PSPRS) comprising 28 items in six categories: daily activities (by history), behavior, bulbar, ocular motor, limb motor and gait/midline The available total score ranges from 0 to 100; lower scores reflect better outcome.
  • Changes in activities of daily living as measured by Progressive Supranuclear Palsy Rating Scale (PSPRS) [ Time Frame: 6 months ]
    Activities of daily living as measured by Progressive Supranuclear Palsy Rating Scale (PSPRS) comprising 28 items in six categories: daily activities (by history), behavior, bulbar, ocular motor, limb motor and gait/midline The available total score ranges from 0 to 100; lower scores reflect better outcome.
  • Changes in behavior as measured by Progressive Supranuclear Palsy Rating Scale (PSPRS) [ Time Frame: 6 months ]
    Behavior as measured by Progressive Supranuclear Palsy Rating Scale (PSPRS) comprising 28 items in six categories: daily activities (by history), behavior, bulbar, ocular motor, limb motor and gait/midline The available total score ranges from 0 to 100; lower scores reflect better outcome.
