The Stanford Parkinson's Disease Plasma Study

Completed · Phase 1

Conditions studied: Parkinson Disease(PD)

In brief

The purpose of this study is to demonstrate that young plasma infusions can be performed safely in patients with Parkinson's Disease (PD). Secondary outcomes will include behavioral and laboratory data that will support the next study that will inquire whether young plasma infusions improve or slow the progression of cognitive, mood and/or motor impairment and rate markers of the disease.

You may qualify if…

A diagnosis of clinically probable or established Parkinson's Disease (MDS criteria)
Subject must be on a stable dose of dopaminergic medication and/or Deep Brain Stimulation (DBS) parameters for at least 4 weeks prior to screening and for the duration of the study
Subject must be competent to sign consent
Subject must be willing to commit to being available for testing and infusions for 6 consecutive weeks (2 testing consecutive weeks, 4 infusion consecutive weeks) followed by two visits a month after final infusion.
The availability of a study partner who knows the patient well and is willing to accompany the subject to all trial (optional if participant is able to consent and travel by self)

You may not qualify if…

The participation in any other interventional clinical trial
The inability to travel to Stanford
Inability to walk without assistance in the off or on medication state
The clinically determined presence of dementia
A clinical suspicion/diagnosis of Multiple System Atrophy (MSA), Progressive Supranuclear Palsy (PSP), Lewy Body Dementia (LBD), Essential Tremor (ET)
Subject's pregnancy or likelihood of pregnancy within the next 6 months.
Subject's positive test results for Hepatitis B, Hepatitis C or HIV at screening
Any other condition or situation that the investigator believes may interfere with the safety of the subject or the intent and conduct of the study
Subject's medical history of:
Stroke Anaphylaxis Gout- may cause an increase in uric acid Prior adverse reaction to any human blood product Any history of a blood coagulation disorder or hypercoagulability Congestive heart failure Uncontrolled hypertension Renal failure Prior intolerance to intravenous fluids Recent history of uncontrolled atrial fibrillation immunoglobulin A deficiency (by history)
Subject's relation to medications or other treatments:
Any concurrent use of an anticoagulant therapy. Antiplatelet drugs (e.g., aspirin or clopidogrel) are acceptable.
The use of Inosine, which may alter urate levels
Initiation or change in the dosage of a cholinesterase inhibitor or memantine during the trial. A participant already on a cholinesterase inhibitor or memantine must be on a stable dose for at least one month prior to Screening.
Concurrent participation in another interventional treatment trial for Parkinson's disease. If there was prior participation, the last dose of the investigational agent must have been at least 6 months prior to Screening.
Treatment with any human blood product, including intravenous immunoglobulin, during the 6 months prior to Screening or during the trial.
Concurrent daily treatment with benzodiazepines, typical or atypical antipsychotics, long-acting opioids, or other medications that, in the investigator's opinion, interfere with cognition. Intermittent treatment with short-acting benzodiazepines or atypical antipsychotics may be permitted, provided that no dose is administered within the 72 hours preceding any cognitive assessment.
