Clinical Trial Summary

This is a multicenter, parallel-group, rater-blinded, randomized clinical study in subjects with advanced PD investigating the efficacy, PK, safety and tolerability of continuous SC infusion of 2 dosing regimens of ND0612H, a solution of LD/CD delivered via a pump system as a continuous SC infusion, compared to standard oral LD/CD. After screening, subjects will undergo 1 day of standard oral LD/CD inpatient dosing followed by 2 days of inpatient treatment with 1 of 2 randomly allocated (1:1 randomization ratio) dosing regimens of ND0612H continuous SC infusion. Subjects will then continue on a maintenance dose of the assigned ND0612H dosing regimen for the next 25 days. A safety visit will be performed 4 weeks after the last SC administration of the study drug for a total of about 2.5 months of participation for each subject enrolled into the trial.

Description:

This phase IIa randomized, controlled, parallel-group study will be conducted in 36 subjects with advanced PD who are treated with oral LD/CD at a stable dose and have predictable morning "OFF" periods and at least 2.5 hrs of daily "OFF" periods. The study will investigate the efficacy, PK, safety and tolerability of continuous SC infusion of 2 dosing regimens of ND0612H. Regimen 1 will employ continuous infusion for 24 hrs using a low infusion rate at night and a higher rate at daytime with supplemental administration of oral immediate release (IR) LD/CD in the mornings. During the inpatient period of about 3 days, the site staff will manage the administration and replacement of the infusions. On Day 4 subjects will be discharged home after they and their study partners have received training on the administration of the infusion. Subjects will then continue on a maintenance dose of the assigned ND0612 dosing regimen for the next 25 days. A safety visit will be performed 4 weeks after the last SC administration of the study drug.

7. Renal or liver dysfunction that may alter drug metabolism including: serum creatinine >1.3 mg/dL, serum aspartate aminotransferase (AST) or alanine aminotransferase (ALT) >2 x upper limit of normal (ULN), total serum bilirubin >2.5 mg/dL.

8. Subjects who are not willing to operate the pump system.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Daily "OFF" Time	Based on Parkinson's disease symptom assessment, "ON" time is when there is good response to medication and few symptoms. "OFF" time is when no there is no response to medication and significant motor symptoms. An "ON/OFF" Log was completed by a blinded rater starting before the first dose of LD/DDI and following the first dose at 30 min intervals for 8 hrs. The changes in "OFF" time as hours (normalized to 16 hrs of awake time) during the 8 hrs of data collection were estimated. Negative change from baseline for "OFF" time indicates improvement.	Baseline to Day 28
Secondary	The Percentage of Subjects With Full "ON" at Approximately 08:00 and Approximately 09:00, as Determined by the Subject	Based on Parkinson's disease symptom assessment, "ON" time is when there is good response to medication and few symptoms. "OFF" time is when no there is no response to medication and significant motor symptoms. Subjects were asked to indicate when exactly in their opinion they had turned to full "ON" (i.e. an "ON" response comparable to the "ON" response to standard oral LD/DDI treatment). Higher percentage of subjects with full "ON" on Day 28 indicates improvement.	Baseline to Day 28
Secondary	Change in Daily "Good ON" Time as Assessed by a Blinded Rater	Based on Parkinson's disease symptom assessment, "ON" time is when there is good response to medication and few symptoms. "OFF" time is when no there is no response to medication and significant motor symptoms. "Good ON" time means "ON" time without troublesome dyskinesia (involuntary muscle movement), defined as the sum of "ON" time without dyskinesia and "ON" time with non-troublesome dyskinesia. An "ON/OFF" Log was completed by a blinded rater starting before the first dose of LD/DDI and following the first dose at 30 min intervals for 8 hrs. Daily total scores were normalized to 16 hours of awake time. Positive change from baseline for "ON" time without dyskinesia and for "Good ON" time, and a negative change in "ON" time with moderate or severe (troublesome) dyskinesia indicates improvement.	Baseline to Day 28
Secondary	Change in Morning UPDRS Part III (Motor) Scores	The Unified Parkinson's Disease Rating Scale (UPDRS) is an Investigator-used rating tool to follow the longitudinal course of Parkinson's disease. UPDRS part III (motor) score is calculated as the sum of the individual UPDRS items 18-31, each of which are measured on a 5-point scale (i.e., 0 is normal and 4 indicates a severe abnormality). UPDRS part III was done as a motor examination on Day 1 before the first dose of standard oral LD/DDI and at the same time on Day 28. The range of score values is from 0 to 132. Higher scores correlate with greater motor impairment.	Baseline to Day 28
Secondary	Change in UPDRS Part II (ADL) Scores	The Unified Parkinson's disease rating scale (UPDRS) is an Investigator-used rating tool to follow the longitudinal course of Parkinson's disease. The UPDRS Part II (activity of daily living) score was calculated as the sum of the individual UPDRS items 5-17. The Part II score is the sum of the answers to the 13 questions that comprise Part II, each of which are measured on a 5-point scale (i.e., 0 is normal and 4 indicates a severe abnormality). The range of score values is from 0 to 52. Higher scores correlate with greater impairments for daily activities.	Baseline to Day 28
Secondary	CGI-Improvement (CGI-I) Score as Assessed by Investigator	Global improvement was rated by the investigator or designee using Clinical Global Impression of Improvement (CGI-I). The CGI-I employs a 7-point scale with 1 being "very much improved" and 7 being "very much worse" for improvement rating.	Baseline to Day 28
Secondary	Change in PDSS-2 Total Score	The quality of night sleep was rated by the subjects using the Parkinson's Disease Sleep Scale (PDSS)-2, which includes questions addressing 15 commonly reported symptoms associated with sleep disturbance in PD. Each question is assessed from 0 (Always) to 10 (Never). The total score values range from 0 to 150. Higher scores indicate a lower quality of sleep, i.e., a reduction in the score indicates an improvement in sleep quality.	Baseline to Day 27
Secondary	Change in PDQ-39 Summary Index and the 8-dimension Scores	Subjects were requested to rate their quality of life using the Quality of Life in Parkinson's Disease (PDQ)-39, a 39-item, self-administered questionnaire with 8 discrete dimensions (mobility, activities of daily living, emotional well-being, stigma, social support, cognition, communication, and bodily discomfort.). The PDQ-39 Summary Index is the sum of the dimension scores divided by the number of dimensions. The total score values range from 0 to 100%. Higher scores indicate a worse quality of life.	Baseline to Day 27
