A Phase 3 Study of TVP-1012 (1 mg) in Early Parkinson's Disease Patients

Phase 3

Completed

• Conditions: Parkinson's Disease
• Interventions: Drug: Placebo; Drug: TVP-1012

• Registration Number: NCT02337725
• Lead Sponsor: Takeda

Brief Summary

The purpose of this study is to evaluate the efficacy and safety of TVP-1012 (1 mg/day) administered to Japanese patients with early Parkinson's disease.

Detailed Description

This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group, phase 3 study to evaluate the efficacy and safety of TVP-1012 in Japanese participants with early Parkinson's disease.

The study period consisted of a 28-week trial period. The participants who fulfill the inclusion criteria and not meeting any of the exclusion criteria were enrolled, and randomized in a 1:1 ratio to either the 1 mg of TVP-1012 or the placebo group. In each treatment group, participants received either 1 mg of TVP-1012 or placebo once daily in a double-blinded manner.

TVP-1012 1 mg	TVP-1012	For 2 weeks during the run-in period, one tablet of placebo orally, once daily before or after breakfast, followed by 26 weeks during the treatment period, one tablet of TVP-1012 1 mg orally, once daily before or after breakfast.

Primary Outcome Measures

Name	Time	Method
Change From Baseline in Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part II + Part III Total Score	From Baseline to Week 26 (LOCF)	Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) retains the four-scale structure with a reorganization of the various subscale; (Part I; 13 items) non-motor experiences of daily living, (Part II; 13) motor experiences of daily living, (Part III; 34) motor examination, and (Part IV; 6) motor complications. Each items had 0-4 ratings, where 0 (normal) to 4 (severe) and score for each was summed to calculate the total scores. The scale range for Part II+III Total Score was 0-188, with higher scores reflecting greater severity.

Secondary Outcome Measures

Name	Time	Method
Number of Participants With TEAE Related to Body Weight	Up to Week 26
Change From Baseline in MDS-UPDRS Part I Total Score	Baseline and Week 26 (LOCF)	For MDS-UPDRS Part I (non-motor experiences of daily living) scores, the scale range for Part I Total Score was 0-52, with higher scores reflecting greater severity.
Number of Participants With Markedly Abnormal Vital Signs Values	Up to Week 26
Number of Participants With TEAE Related to Electrocardiograms (ECG)	Up to Week 26
Change From Baseline in MDS-UPDRS Part II Total Score	Baseline and Week 26 (LOCF)	For MDS-UPDRS Part II (motor experiences of daily living) scores, the scale range for Part II Total Score was 0-52, with higher scores reflecting greater severity.
Change From Baseline in MDS-UPDRS Part III Total Score	Baseline and Week 26 (LOCF)	For MDS-UPDRS Part III (motor examination) scores, the scale range for Part III Total Score was 0-132, with higher scores reflecting greater severity.
