Of the other two efficacy measures, finger-tapping scores have not been extensively validated, and various derivations of minimal clinically relevant changes in UPDRS scores have not resolved the issue of what clearly constitutes a meaningful change in a given patient or population.14,15,1719 By observers assessments, the mean duration of an on state (~5.6 hours after ER CD-LD dosing compared with ~2.7 hours after IR CD-LD dosing) was matched most closely by a $20% improvement in finger-tapping, a $11-point improvement in UPDRS Part III score, and a levodopa plasma concentration $1,000 ng/mL, suggesting that these values may be the most clinically relevant thresholds for acute assessment of benefit, at least in this population of PD patients.

Physicians should consider dose Among 27 patients, mean time to onset of an on state was similar for ER compared with IR CD-LD (0.83 vs 0.81 hour), but mean duration was significantly longer for ER CD-LD than for IR CD-LD (5.56 vs 2.69 hours; P<0.0001). For the post hoc analyses presented here, we were interested in comparing the onset and duration of benefit of ER CD-LD and those of IR CD-LD in patients with motor fluctuations, using data from a Phase II crossover study.8 Trained rater assessments of on and off states provide a straightforward means to determine onset and duration of benefit, but finger-tapping and UPDRS motor scores improve and decline gradually, with no clearly defined thresholds that separate benefit from no benefit.
