A Long-Term Extension Trial From Phase II/III of SPM 962 in Early Parkinson's Disease Patients

An Open-label Long-term Extension Trial From Phase II/III of SPM962 (243-07-001) in Early Parkinson's Disease Patients With Non-concomitant Treatment of L-dopa

Safety of SPM 962 in a once-daily repeated long-term treatment in Parkinson's disease patients who are not concomitantly treated with L-dopa will be investigated with a doses.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Incidence and Severity of Adverse Events, Vital Signs, and Laboratory Parameters	Incidence and severity of adverse events, vital signs, and laboratory parameters up to 54 weeks after dosing. *decrease in difference between supine and standing systolic blood pressure	Up to 55 weeks after dosing
Skin Irritation Score of the Application Site	Skin irritation score of the application site were evaluated according to the criteria below. The worst score throughout the treatment period was used in the analysis. -: no reaction, ±: mild erythema, +: erythema, ++: erythema and Oedema, +++: erythema and oedema and rash papular, or serous papule, or vesicles, ++++: bullosum	Up to 55 weeks after dosing

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Total of Unified Parkinson's Disease Rating Scale (UPDRS) Part 2 Sum Score and Part 3 Sum Score	Mean change (LOCF) from baseline in Total of UPDRS Part 2 sum score and Part 3 sum up to 54 weeks after dosingUPDRS is a scale for monitoring Parkinson's Disease-related disability and impairment. The UPDRS consists of the following four sub-scales. Part 1: Mentation, Part 2: Activities of Daily Living, Part 3: Motor, Part 4: Complications. Part 2 assesses 13 items and Part 3 assesses 14 items. Each item is scored from 0 (normal) to 4 (severe). The sum score serves as the sub-scale score. A higher score indicates a greater severity of symptoms. Thus a decrease in the scores means improvement.	Baseline, Up to 54 weeks after dosing
