Estimates of the Short-term Efficacy of Talineuren (TLN) and Placebo in Patients With Parkinson Disease

This study is double-blinded placebo controlled to estimate the short-term efficacy of Talineuren. The investigational Medicinal Product (IMP) is administrated 18 times intravenously as an add-on therapy to the standard of care Parkinson medication. Talineuren is a liposomal formulation containing GM1 (monosialotetrahexosylganglioside) as the pharmacological active substance. The results of this pilot study are essential for the sample size calculation of a subsequent larger phase II/III trial.
