Evaluation of rotigotine transdermal patch for the treatment of apathy and motor symptoms in Parkinson's disease.

ABSTRACT: This multicenter, double-blind, placebo-controlled study assessed the efficacy of rotigotine transdermal patch on apathy and motor symptoms in patients with Parkinson's disease (PD).Patients with PD-associated apathy (Unified Parkinson's Disease Rating Scale [UPDRS] I item 4 [motivation] ?2 and patient-rated Apathy Scale [AS] ?14) were randomized 1:1:1 to "low-dose" rotigotine (?6 mg/24 h for early PD [those not receiving levodopa] or ?8 mg/24 h for advanced PD [those receiving levodopa]), "high-dose" rotigotine (?8 mg/24 h for early PD or ?16 mg/24 h for advanced PD), or placebo, and maintained at optimal/maximal dose for 12 weeks. Coprimary efficacy variables were: change from baseline to End of Maintenance in patient-rated AS and UPDRS II?+?III total score. Recruitment was stopped after an interim futility analysis; therefore, all p values are exploratory.Of 122 patients randomized, 81.1 % completed the study (placebo, n?=?32/40 [80.0 %]; low-dose rotigotine, n?=?30/41 [73.2 %]; high-dose rotigotine, n?=?37/41 [90.2 %]). No treatment difference was observed in the change in patient-rated AS (least squares mean [95 % confidence interval (CI)] difference: low-dose, 0.04 [-2.42, 2.50], p =0.977; high-dose, -0.22 [-2.61, 2.18], p?=?0.859). Rotigotine improved UPDRS II?+?III total scores versus placebo (least squares mean [95 % CI] treatment difference: low-dose, -7.29 [-12.30, -2.28], p?=?0.005; high-dose, -6.06 [-10.90, -1.21], p?=?0.015), and the "mood/apathy" domain of the Non-Motor Symptom Scale as rated by the investigator (secondary outcome). The most frequent adverse events in rotigotine-treated patients were application site reactions, somnolence, and nausea.Rotigotine did not improve PD-associated apathy as rated by the patient but provided clinically relevant improvement in motor control and activities of daily living.ClinicalTrials.gov identifier NCT01782222 . Trial registration date: January 30, 2013.

Project description:Objective: The effects of rotigotine transdermal patch (RTG) on the neuropsychiatric symptoms of Parkinson's disease (PD) outcomes remain controversial. The aim of this review was to determine the efficacy and safety of RTG on the neuropsychiatric symptoms of PD. Methods: In this systematic review and meta-analysis, PubMed, Cochrane Library, EMBASE, and Web of Science were searched for randomized controlled trials comparing RTG and placebo in PD up to May 10, 2021. We analyzed the data using Review Manager 5.2 software. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation Approach. In order to avoid false-positive results caused by random error, we use TSA software for trial sequential analysis (TSA). Results: We included 10 studies (1,844 patients). The meta-analysis showed that, compared with placebo, RTG can significantly improve the scores for Apathy Scale (MD = -1.68, 95% confidence interval, CI: -2.74 to -0.62, P = 0.002; moderate certainty), Beck Depression Inventory-II (MD = -1.19, 95% CI: -2.26 to -0.11, P = 0.03; moderate certainty), the Non-Motor Symptoms Scale (MD = -3. 66, 95% CI: -4. 30 to -3.01, P < 0.00001; moderate certainty), the sleep/fatigue domains of the Parkinson's Disease Non-motor Symptom Assessment Scale (MD = -2.03, 95% CI: -3.08 to -0.98, P = 0.0001; moderate certainty), the mood/apathy domains of the Non-motor Symptom Scale (MD = -2.48, 95% CI: -4.07 to -0.89, P = 0.002; high certainty), the eight-item Parkinson's Disease Questionnaire (MD = -4. 93, 95% CI: -6.79 to -3.07, P < 0.00001; moderate certainty), and the 39-item Parkinson's Disease Questionnaire (MD = -3.52, 95% CI: -5.25 to -1.79, P < 0.0001; high certainty). However, there was no statistically significant difference on the Snaith-Hamilton Pleasure Scale (MD = -0.12, 95% CI: -0.58 to 0.34, P = 0.61). Our results showed that RTG exerts a positive effect on sleep. According to the TSA, the results implied that, except for the Beck Depression Inventory-II, conclusive evidence have been obtained in the RTG group. It has been proven in our meta-analysis that rotigotine has good safety and tolerability. Conclusions: RTG can effectively improve the neuropsychiatric symptoms, sleep quality, and quality of life in patients with PD.

Project description:Pain is a troublesome non-motor symptom of Parkinson's disease (PD). The RECOVER (Randomized Evaluation of the 24-hour Coverage: Efficacy of Rotigotine; Clintrials.gov: NCT00474058) study demonstrated significant improvements in early-morning motor function (UPDRS III) and sleep disturbances (PDSS-2) with rotigotine transdermal system. Improvements were also reported on a Likert pain scale (measuring any type of pain). This post hoc analysis of RECOVER further evaluates the effect of rotigotine on pain, and whether improvements in pain may be attributable to benefits in motor function or sleep disturbance.PD patients with unsatisfactory early-morning motor impairment were randomized to optimal-dose (up to 16 mg/24 h) rotigotine or placebo, maintained for 4 weeks. Pain was assessed in the early-morning using an 11-point Likert pain scale (rated average severity of pain (of any type) over the preceding 12 hours from 0 [no pain] to 10 [worst pain ever experienced]). Post hoc analyses for patients reporting 'any' pain (pain score ?1) at baseline, and subgroups reporting 'mild' (score 1-3), and 'moderate-to-severe' pain (score ?4) were performed. Likert pain scale change from baseline in rotigotine-treated patients was further analyzed based on a UPDRS III/PDSS-2 responder analysis (a responder defined as showing a ?30% reduction in early morning UPDRS III total score or PDSS-2 total score). As post hoc analyses, all p values presented are exploratory.Of 267 patients with Likert pain data (178 rotigotine, 89 placebo), 187 (70%) reported 'any' pain; of these 87 (33%) reported 'mild', and 100 (37%) 'moderate-to-severe' pain. Change from baseline pain scores decreased with rotigotine compared with placebo in patients with 'any' pain (-0.88 [95% CI: -1.56, -0.19], p?=?0.013), and in the subgroup with 'moderate-to-severe' pain (-1.38 [-2.44, -0.31], p?=?0.012). UPDRS III or PDSS-2 responders showed greater improvement in pain than non-responders.The results from this post hoc analysis of the RECOVER study suggest that pain was improved in patients with PD treated with rotigotine; this may be partly attributable to benefits in motor function and sleep disturbances. Prospective studies are warranted to investigate this potential benefit and the clinical relevance of these findings.

Project description:Background and objectivesRotigotine is a dopamine receptor agonist with activity across the D1 through to D5 receptors as well as select serotonergic and adrenergic sites; continuous transdermal delivery of rotigotine with replacement of the patch once daily maintains stable plasma concentrations over 24 h. Rotigotine is indicated for the treatment of early and advanced-stage Parkinson's disease and moderate-to-severe idiopathic restless legs syndrome. The pharmacokinetics and pharmacodynamics of a drug may vary between subjects of different ethnic origin. This study evaluated the pharmacokinetics, safety, and tolerability of single-dose treatment with rotigotine transdermal patch in Japanese and Caucasian subjects.MethodsIn this open-label, parallel-group study, healthy male and female subjects of Japanese or Caucasian ethnic origin were matched by sex, body mass index, and age. A single transdermal patch delivering 2 mg/24 h rotigotine (patch content 4.5 mg) was applied to the ventral/lateral abdomen for 24 h. The main outcome measures were the plasma concentrations of unconjugated and total rotigotine and its desalkyl metabolites and derived pharmacokinetic parameters (area under the concentration-time curve from time zero to last quantifiable concentration [AUClast], maximum plasma concentration [Cmax], and body weight- and dose-normalized values).ResultsThe pharmacokinetic analysis included 48 subjects (24 Japanese, 24 Caucasian). The mean apparent dose of rotigotine was 2.0±0.5 mg for Japanese subjects and 2.08±0.58 mg for Caucasians. Plasma concentration-time profiles of unconjugated rotigotine and of the main metabolites were similar for both ethnic groups. Parameters of model-independent pharmacokinetics, Cmax, time to Cmax (tmax), and AUClast, for unconjugated rotigotine showed no statistically significant differences between Japanese and Caucasian subjects. Values of concentration-dependent pharmacokinetic parameters were higher in female subjects; this difference was minimized after correction for body weight. A statistically significant difference between ethnic groups was observed for total rotigotine concentrations (total rotigotine=unconjugated rotigotine+conjugated rotigotine), with slightly lower values in Caucasians after correction for body weight and apparent dose. No relevant differences were observed between males and females. Inter-individual variability was high. The terminal half-life for unconjugated rotigotine was 5.3 h in Japanese subjects and 5.7 h in Caucasians; corresponding values for total rotigotine were 8.6 h and 9.6 h. Less than 0.1% of the apparent dose was renally excreted as the parent compound. Renal elimination of total rotigotine covers 11.7% of absorbed dose in Japanese subjects and 10.8% of the absorbed dose in Caucasians, whereas the renal elimination via total despropyl rotigotine was 8.2 and 7.1%, respectively. The corresponding values for total desthienylethyl rotigotine were 3.5% in Japanese subjects and 4.2% Caucasians. Most adverse events were mild in intensity and typical for dopamine agonists or for transdermal therapeutics.ConclusionAdministration of a single patch delivering 2 mg/24 h rotigotine resulted in comparable pharmacokinetic profiles in Japanese and Caucasian subjects. The rotigotine transdermal patch was generally well-tolerated. Our findings suggest similar dose requirements for Japanese and Caucasian populations.
