NCT03737773
Non-pharmacological interventional pilot study on the effect of prismatic glasses for the improvement of Pisa syndrome in Parkinson's disease. The study involves 40 patients, of whom 20 receive active treatment and 20 slow placebo. At the end of the study, all patients receive corrective lenses in compassionate use if the study yields positive results.
NCT01155479
This is a one year, 2-part study to determine the efficacy and safety of preladenant, an adenosine type 2a (A2a) receptor antagonist. The purpose of Part 1 (first 26 weeks) is to determine if preladenant is effective in the treatment of early Parkinson's Disease. The purpose of Part 2 (second 26 weeks) is to determine if preladenant is safe and well tolerated. The primary efficacy hypothesis is that at least the 10 mg twice daily dose of preladenant is superior to placebo as measured by the change from Baseline to Week 26 in the sum of Unified Parkinson's Disease Rating Scale (UPDRS) Parts 2 and 3 scores (UPDRS2+3).
NCT01215227
The primary purpose of this extension study is to assess the long-term safety and tolerability of preladenant in participants from parent studies NCT01155466 \[P04938\] and NCT01227265 \[P07037\] with moderate to severe Parkinson's Disease (PD). The study will also characterize the long-term efficacy of preladenant in participants with PD. Participants will continue to receive their stable regimen of levodopa (L-dopa) plus any adjunct medications during the study as prescribed by their physician. Several classes of adjunct medications may be used, including Amantadine, anticholinergics, dopa decarboxylase inhibitors, and dopamine agonists.
