Phase 2

Completed

• Conditions: Parkinson's Disease
• Interventions: Drug: SPM 962

• Registration Number: NCT01631812
• Lead Sponsor: Otsuka Pharmaceutical Co., Ltd.

Brief Summary

The primary objective of this study is to investigate safety of SPM 962 in advanced PD patients in a multi-center, open-label, non-controlled study following once-daily multiple transdermal doses of SPM962 within a range of 4.5 to 36.0 mg (maximum treatment period: 54 weeks).

SPM 962	SPM 962	-

Primary Outcome Measures

Name	Time	Method
Incidence and Severity of Adverse Events, Vital Signs, and Laboratory Parameters.	Up to 55 weeks after dosing	Incidence and severity of adverse events, vital signs, and laboratory parameters after dosing.; \*decrease in difference between supine and standing systolic blood pressure
Skin Irritation Score of the Application Site	Up to 55 weeks after dosing	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

Secondary Outcome Measures

Name	Time	Method
Unified Parkinson's Disease Rating Scale (UPDRS) Part 3 Sum Score	Baseline, Up to 54 weeks after dosing	Mean change (LOCF) from baseline in UPDRS Part 3 sum score (on state) up to 54 weeks after dosing UPDRS 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 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.
UPDRS Part 2 Sum Score	Baseline, Up to 54 weeks after dosing	Mean change (LOCF) from baseline in UPDRS Part 2 sum score (average scores of on state and off state) up to 54 weeks after dosing UPDRS sub-scale Part 2 assesses 13 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.
Absolute Time Spent "Off"	Up to 54 weeks after dosing	Mean number of hours in "off state" during a 24-hour period.
