Change From Baseline in Parkinson's Disease Diary For Participants With Motor Fluctuations at Day 13
Zeitfenster: Baseline, Day 13
|
According to Parkinson's disease diaries of participants "OFF" time was a time period when the medication no longer providing benefit with regard to mobility, slowness, and stiffness and participants experienced relatively poor overall function with worsening of tremor, rigidity, balance, or bradykinesia.
"ON" time was a time period when medication was providing benefit with regard to mobility, slowness, and stiffness.
"ON" time was classified as associated with or without troublesome dyskinesia (TD) that interfere with activities of daily living and with or without dyskinesia.
"OFF" time and "ON" time with TD were generally considered to be "bad time" with regard to motor function, whereas "ON" time without dyskinesia (WD) and with non- troublesome dyskinesia (NTD) were generally considered to be "good time".

Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes.

Terminal half-life is the time measured for the plasma concentration of drug to decrease by one half.
It was calculated as dividing the natural logarithm to the base e (Log e)*2/k el, where k el is the terminal phase rate constant calculated by a linear regression of the log-linear concentration-time curve.
