Clinical Trial Summary

The purpose of this study is to determine the optimal dose of WIN-1001X for its therapeutic confirmatory study by comparing and evaluating the efficacy and safety of each dose group by conducting a therapeutic exploratory study on three dose groups of WIN-1001X 400 mg, 800 mg, and 1200 mg, and placebo group in patients with early Parkinson's disease.

Description:

The primary objective of this study is to evaluate the difference in the change of MDS UPDRS Part Ⅲ between WIN-1001X 400 mg, 800 mg, and 1200 mg as the test drugs compared to placebo as the control drug after administering them for 12 weeks.

The secondary objectives of this study are to evaluate the therapeutic efficacy and safety of the 3 dose groups of WIN-1001X compared to placebo group by assessing the changes in MDS UPDRS Part Ⅲ after administering the investigational products for 4 and 8 weeks, the changes in MDS UPDRS Part Ⅰ, Part Ⅱ, Part Ⅰ+Part Ⅱ+Part Ⅲ, and Modified Hoehn and Yahr scale after administering for 4, 8, and 12 weeks, the changes in K-NMSS (Non-Motor Symptoms Scale), K-MoCA (Korean-Montreal Cognitive Assessment), K-PDQ-39 (Parkinson's Disease Questionnaire) score.

Intervention

Drug:
• WIN-1001X
This study has been designed as a randomized, double-blind, and placebo-controlled study. Once the patients who have voluntarily singed an informed consent form are enrolled in this study, their eligibilities for the study are assessed and those who have satisfied the inclusion/exclusion criteria are randomized to the test group 1 (400mg), 2 (800mg), and 3 (1200mg), or the control group (placebo group) in a ratio of 1:1:1:1. The randomized patients are administered 3 tablets of the investigational product twice a day for 12 weeks and the safety follow-up should be carried out for 2 weeks after administration of the investigational product is terminated.
• Placebo
This study has been designed as a randomized, double-blind, and placebo-controlled study. Once the patients who have voluntarily singed an informed consent form are enrolled in this study, their eligibilities for the study are assessed and those who have satisfied the inclusion/exclusion criteria are randomized to the test group 1 (400mg), 2 (800mg), and 3 (1200mg), or the control group (placebo group) in a ratio of 1:1:1:1. The randomized patients are administered 3 tablets of the investigational product twice a day for 12 weeks and the safety follow-up should be carried out for 2 weeks after administration of the investigational product is terminated.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in MDS UPDRS Part ?	Change in Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part III. MDS-UPDRS Part III measures motor examination. Part III consists of 33 scores based on 18 items, and each question is anchored with five response scale from 0(normal) to 4(severe).	From baseline (0d) after administration of the investigational product for 12 weeks
Secondary	Change in the MDS UPDRS Part ?	Change in Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part III. MDS-UPDRS Part III measures motor examination. Part III consists of 33 scores based on 18 items, and each question is anchored with five response scale from 0(normal) to 4(severe).	After administration of the investigational product for 4 and 8 weeks
Secondary	Change in the MDS UPDRS Part ?	Change in Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part I. MDS-UPDRS Part I measures non-motor experiences of daily living. Part I consists of 13 questions/evaluations, and each question is anchored with five response scale from 0(normal) to 4(severe).	After administration of the investigational product for 4, 8, and 12 weeks
Secondary	Change in the MDS UPDRS Part ?	Change in Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part II.

MDS-UPDRS Part I measures non-motor experiences of daily living, Part II measures motor experiences of daily living and Part III measures motor examination.

After administration of the investigational product for 4, 8, and 12 weeks
Secondary	Change in the Modified Hoehn and Yahr scale	The Hoehn and Yahr scale is a commonly used system for describing how the symptoms of Parkinson's disease progress. The Hoehn and Yahr scale includes stages 1 through 5, with addition of stages 1.5 and 2.5 to help describe the intermediate course of the disease. The higher the score, the more severe the symptoms of Parkinson's disease progress.	After administration of the investigational product for 4, 8, and 12 weeks
Secondary	Changes in each and total scores of K-NMSS	Korean version of Novel Non-Motor Symptoms Scale for Parkinson's Disease is 30-item scale containing nine dimensions: cardiovascular, sleep/fatigue, mood/cognition, perceptual problems, attention/memory, gastrointestinal, urinary, sexual function and miscellany. Each symptoms are scored with severity (0=none, 1=mild, 2=moderate) and frequency (1=rarely, 2=often, 3=frequent, 4=very frequent). The final scores are calculated as severity score x frequency score. The higher the score, the severe the symptoms.	After administration of the investigational product for 4 and 12 weeks
Secondary	Change in the K-MoCA	The Montreal Cognitive Assessment (MoCA) is a screening assessment for detecting cognitive impairment. It is a 30-point test consisting of attention and concentration, executive functions, memory, language, visuoconstructional skills, conceptual thinking, calculations, and orientation. The total possible score is 30 points and a score of 26 or above is considered normal.	After administration of the investigational product for 4 and 12 weeks
Secondary	Changes in the summary index and total scores of the K-PDQ-39	The PDQ-39 is a 39-item self-report questionnaire, which assesses Parkinson's disease-specific health related quality over the last month. Assessment is carried out across the 8 quality of life dimensions; activities of daily living, attention & working memory, cognition, communication, depression, functional mobility, quality of life, social relationships and social support. All items are scored from 0 (never) to 4 (always). Dimension score is then calculated by sum of scores of each item in the dimension divided by the maximum possible socre of all the items in the dimension, multiplied by 100. Lower dimension score reflects better quality of life.	After administration of the investigational product for 4 and 12 weeks
