Pooled Analyses of Phase III Studies of ADS-5102 (Amantadine) Extended-Release Capsules for Dyskinesia in Parkinson's Disease.
Trial report in CNS drugs, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. It is linked to 2 registered trials, which are not on this map. Cited by 34 papers, 2 of them syntheses that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract
backgroundAlthough levodopa is considered the most effective pharmacotherapy for motor symptoms of Parkinson's disease (PD), chronic use is associated with motor complications, including fluctuating response and unpredictable, involuntary movements called dyskinesia. ADS-5102 (amantadine) extended-release (ER) capsules (GOCOVRI
objectiveIn this study, we present pooled results from two randomized, double-blind, placebo-controlled, phase III ADS-5102 trials. PATIENTS AND
methodsThe two studies in PD patients with dyskinesia shared design and eligibility criteria, differing only in treatment duration. Results from common assessment time points were pooled.
resultsAt 12 weeks, the least squares (LS) mean change in total score on the Unified Dyskinesia Rating Scale among 100 patients randomized to ADS-5102 and 96 patients randomized to placebo was - 17.7 (standard error [SE] 1.3) vs. - 7.6 (1.3) points, respectively (- 10.1 points, 95% confidence interval [CI] - 13.8, - 6.5; p < 0.0001). The relative treatment difference between groups was 27.3% (p < 0.0001). At 12 weeks, the LS mean change in OFF time was - 0.59 (0.21) vs. +0.41 (0.20) h/day, a difference of - 1.00 h/day (95% CI - 1.57, - 0.44; p = 0.0006). For both efficacy measures, a significant difference from placebo was attained by two weeks, the first post-baseline assessment, and was maintained throughout 12 weeks. In the pooled ADS-5102 group, the most common adverse events were hallucination, dizziness, dry mouth, peripheral edema, constipation, falls, and orthostatic hypotension.
conclusionsThese analyses provide further evidence supporting ADS-5102 as an adjunct to levodopa for treating both dyskinesia and OFF time in PD patients with dyskinesia. Clinicaltrials.gov identifier: NCT02136914 and NCT02274766.
