NCT06431971

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Movement Disorder Society Unified Parkinson's Disease Rating Scale score

    The Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) will be used by the patient and physician to evaluate various symptoms of Parkinson disease including non-motor and motor experiences of daily living and motor complications. The MDS-UPDRS Scale consists of 4 parts: * Part 1 (Nonmotor aspects of experiences of daily living) with 13 items. * Part 2 (Motor aspects of experiences of daily living) with 13 items. * Part 3 (Motor examination) with 18 items. * Part 4 (Motor complications) with 6 items. Each item is rated with 0=normal, 1=slight, 2=mild, 3=moderate, 4=severe. The lower the score, the fewer / less severe the symptoms.

    Baseline, week 7, 11, 15, 19 and 22

Secondary Outcomes (3)

  • Parkinson disease Quality of Life Questionnaire score

    Baseline, week 19

  • Montreal Cognitive Assessment score

    baseline, week 19

  • Change in Levodopa equivalent daily dose

    Through study completion, an average of 22 weeks

Other Outcomes (3)

  • Number of IMP-related adverse events

    From the date of the first administration until week 22

  • Proportion of feasibility parameters

    Up to week 22

  • Mean values of Biomarkers

    Baseline, week 19
