Official title

A Phase 1, Open-label Study to Validate Treatment-induced Biomarkers Following Sargramostim Treatment in Parkinson's Disease

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Investigators will evaluate the safety of a 48 week regimen of Leukine administered as a weight-based dose at 3 ug/kg/ day for 5 days followed by a 2-day holiday. This 48 week long study will extend the prior biomarker evaluations observed in a previous study. 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). Leukapheresis will be performed to collect large numbers of immune cells for biomarker testing and immune phenotyping. Additionally, the investigators will determine whether 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.
