Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Frequency of adverse events	Adverse events to evaluate the safety and tolerability of LY03003	From screening up to day 50
Secondary	Time of maximum concentration (Tmax) of total LY03003		From the first injection of stable doses up to day 50
Secondary	Maximum concentration in plasma (Cmax) of total LY03003		From the first injection of stable doses up to day 50
Secondary	Area under the concentration-time curve (AUC) from zero up to the last measured concentration [AUC (0-t)] of LY03003		From the first injection of stable doses up to day 50
Secondary	Area under the concentration-time curve (AUC) from time zero up to the infinite time [AUC (0-8)] of LY03003		From the first injection of stable doses up to day 50
Secondary	Apparent volume of distribution (Vd) of LY03003		From the first injection of stable doses up to day 50
Secondary	Terminal half-life (t1/2) of total LY03003		From the first injection of stable doses up to day 50
Secondary	Total body clearance of LY03003		From the first injection of stable doses up to day 50

Secondary	Change from baseline to the end of the treatment period in the Unified Parkinson's Disease Rating Scale (UPDRS) part (?+?) Total Score	The Unified Parkinson´s Disease Rating Scale Part ? measures "Activities in Daily Living". The total score ranges from 0 (Best score possible) to 52 (Worst score possible).; The Unified Parkinson´s Disease Rating Scale Part ? is an accepted and validated scale for the assessment of motor function in Parkinson´s disease. Each of the 27 sub-items in the UPDRS III is measured on a scale of 0 to 4, where 0 is normal and 4 represents severe abnormalities. The total scores therefore ranges from 0 to 108.
