A Dose-ranging Study for SPM 962 in Parkinson's Disease Patients

A Open-label Dose-ranging Study for SPM 962 in Parkinson's Disease Patients

The primary objective of this trial is to establish the maximum maintenance dose of SPM 962 in patients with Parkinson's disease in a multi-center, uncontrolled, open-label study by conducting safety evaluation of each patient following once-daily transdermal doses of SPM 962 within a range of 4.5 to 36.0 mg. (The administration period will consist of a standard 8-week dose-titration period, 4-week dose-maintenance period, and a dose de-escalation period) Exploratory evaluation of each patient's maintenance dose will also be conducted with attention to patient safety. The relationship of pharmacokinetics, safety, and efficacy will also be examined.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Maintenance Dose of the SPM962	The maintenance dose of the SPM 962 was examined based on the safety and efficacy.	Up to 12 weeks after dosing

Secondary 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 following the initiation of study treatment.	Up to 12 weeks after dosing
Total of Unified Parkinson's Disease Rating Scale (UPDRS) Part 2 Sum Score and Part 3 Sum Score for Early Parkinson's Disease Without Concomitant L-dopa Therapy	Mean change (LOCF) from baseline in Total of UPDRS Part 2 sum score and Part 3 sum at 12 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 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, 12 weeks after dosing
UPDRS Part 3 Sum Score for Advanced Parkinson's Disease With Concomitant L-dopa Therapy	Mean change (LOCF) from baseline in UPDRS Part 3 sum score at 12 weeks after dosing. UPDRS sub-scale 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, 12 weeks after dosing
UPDRS Part 2 Sum Score for Early Parkinson's Disease Without Concomitant L-dopa Therapy	Mean change (LOCF) from baseline in UPDRS Part 2 sum score at 12 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.	Baseline, 12 weeks after dosing
UPDRS Part 3 Sum Score for Early Parkinson's Disease Without Concomitant L-dopa Therapy	Mean change (LOCF) from baseline in UPDRS Part 3 sum score at 12 weeks after dosing. UPDRS sub-scale 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, 12 weeks after dosing
UPDRS Part 2 Sum Score (on State) for Advanced Parkinson's Disease With Concomitant L-dopa Therapy.	Mean change (LOCF) from baseline in UPDRS Part 2 sum score (on state) at 12 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.	Baseline, 12 weeks after dosing
UPDRS Part 2 Sum Score (Off State) for Advanced Parkinson's Disease With Concomitant L-dopa Therapy.	Mean change (LOCF) from baseline in UPDRS Part 2 sum score (off state) at 12 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.	Baseline, 12 weeks after dosing
UPDRS Part 2 Sum Score (Average Score of on State and Off State) for Advanced Parkinson's Disease With Concomitant L-dopa Therapy	Mean change (LOCF) from baseline in UPDRS Part 2 sum score (average score of on state and off state) at 12 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.	Baseline, 12 weeks after dosing
Total of UPDRS Part 2 Sum Score (Average Score of on State and Off State) and Part 3 Sum Score for Advanced Parkinson's Disease With Concomitant L-dopa Therapy	Mean change (LOCF) from baseline in Total of UPDRS Part 2 sum score (average score of on state and off state) and Part 3 sum score at 12 weeks after dosing. UPDRS sub-scale 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, 12 weeks after dosing
Off Time for Advanced Parkinson's Disease With Concomitant L-dopa Therapy	Mean change (LOCF) from baseline in off time at 12 weeks after dosing.	Baseline, 12 weeks after dosing
