概要
RESULTS
One hundred seventeen patients were randomized into the study (mean age 67.0 years; daily "off" time 5.3 hours; mean daily levodopa dose 610 mg). Carryover-adjusted mean changes from baseline "off" times were during ODM-101/65, -1.53 hours (p = 0.02 vs LCE), during ODM-101/105, -1.57 hours (p = 0.01 vs LCE), and during LCE -0.91 hours. Changes in daily "on" time without dyskinesia were 1.54 hours (p = 0.005 vs LCE), 1.38 hours (p = 0.0214 vs LCE), and 0.69 hours, respectively. Changes in "on" time with troublesome dyskinesia were <0.1 hours and not significantly different between treatments. In patients with high-activity COMT genotypes Val/Met or Val/Val, "off" time was reduced more with ODM-101/65 and ODM-101/105 than with LCE (p = 0.015 and p = 0.006). No difference between the treatments was seen in safety and tolerability. The most common treatment-related adverse effects were nausea, dizziness, drug-effect decrease, and dyskinesia, which were in most cases mild or moderate in severity. Treatment-related serious adverse events were diarrhea (ODM-101/105 and LCE), and myocardial ischemia and blood creatine kinase increase (LCE).
