Official title
Safety, Tolerability and Biomarker Assessments of Leukine (Sargramostim) During Extended Timed Treatment for Parkinson's Disease: A Phase I Pilot Study
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
First, the investigators will determine the safety of a 36 month regimen of Leukine administered as a weight-based dose at 3 µg/kg/day for 5 days (week), followed by a 2-day holiday (weekend). This 36 month (n=10) pilot study will extend the prior 2 month observation tests towards the goal of assessing the safety of Leukine for treatment of Parkinson's disease (PD). Clinical signs and symptoms will be measured by personal well-being, physical, and neurological examinations (UPDRS Parts I, II, III, and IV assessments) and blood tests (CBC with differential, total T cell count, and a comprehensive metabolic sera panel). Second, we will assess regimen tolerability administered in a dose reduction, from 6 µg/kg/day without interruption, to 3 µg/kg/day with 2 day drug holidays. The investigators will examine over a time of 36 months, effects of treatment on defined adaptive immune deficits in PD as measured by analysis of peripheral blood mononuclear cells collected before, during, and after cessation of Leukine administration. Individual T cell parameters will be assessed and will include links between T cell function and subset analyses and clinical neurological signs and symptoms. In addition, the functional stability of the immune deficits will be assess in PD by examining T cell subsets in PD patients in this study against prior results. The investigators will also determine whether the immune deficits of PD are consistent during baseline data collection, and the potential Leukine-induced motor control and mobility improvements will be determined by UPDRS part I, II, III, and IV scores off treatment and on treatment.
