Rotigotine Effects on Early Morning Motor Function and Sleep in Parkinson's Disease: A Double-Blind, Randomized, pLacebo-Controlled Study (RECOVER)

In a multinational, double-blind, placebo-controlled trial (NCT00474058), 287 subjects with Parkinson's disease (PD) and unsatisfactory early-morning motor symptom control were randomized 2:1 to receive rotigotine (2–16 mg/24 hr [n = 190]) or placebo (n = 97). Treatment was titrated to optimal dose over 1–8 weeks with subsequent dose maintenance for 4 weeks. Early-morning motor function and nocturnal sleep disturbance were assessed as coprimary efficacy endpoints using the Unified Parkinson's Disease Rating Scale (UPDRS) Part III (Motor Examination) measured in the early morning prior to any medication intake and the modified Parkinson's Disease Sleep Scale (PDSS-2) (mean change from baseline to end of maintenance [EOM], last observation carried forward). At EOM, mean UPDRS Part III score had decreased by −7.0 points with rotigotine (from a baseline of 29.6 [standard deviation (SD) 12.3] and by −3.9 points with placebo (baseline 32.0 [13.3]). Mean PDSS-2 total score had decreased by −5.9 points with rotigotine (from a baseline of 19.3 [SD 9.3]) and by −1.9 points with placebo (baseline 20.5 [10.4]). This represented a significantly greater improvement with rotigotine compared with placebo on both the UPDRS Part III (treatment difference: −3.55 [95% confidence interval (CI) −5.37, −1.73]; P = 0.0002) and PDSS-2 (treatment difference: −4.26 [95% CI −6.08, −2.45]; P < 0.0001). The most frequently reported adverse events were nausea (placebo, 9%; rotigotine, 21%), application site reactions (placebo, 4%; rotigotine, 15%), and dizziness (placebo, 6%; rotigotine 10%). Twenty-four-hour transdermal delivery of rotigotine to PD patients with early-morning motor dysfunction resulted in significant benefits in control of both motor function and nocturnal sleep disturbances. © 2010 Movement Disorder Societ

Rotigotine transdermal system and evaluation of pain in patients with Parkinson's disease:a post hoc analysis of the RECOVER study

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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

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

Background: 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). Methods: 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. Results: 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. Conclusions: 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.

A Randomized Controlled Exploratory Pilot Study to Evaluate the Effect of Rotigotine Transdermal Patch on Parkinson\u27s Disease–Associated Chronic Pain

Pain is a troublesome nonmotor symptom of Parkinson\u27s disease (PD). This double-blind exploratory pilot study (NCT01744496) was the first to specifically investigate the effect of a dopamine agonist on PD-associated pain as primary outcome. Patients with advanced PD (ie, receiving levodopa) and at least moderate PD-associated chronic pain (≥3 months, ≥4 points on 11-point Likert pain scale) were randomized to rotigotine (optimal/maximum dose ≤16 mg/24h) or placebo and maintained for 12 weeks. Primary efficacy variable was change in pain severity (Likert pain scale) from baseline to end of maintenance. Secondary variables included percentage of responders (≥2-point Likert pain scale reduction), King\u27s PD Pain Scale (KPPS) domains, and PD Questionnaire (PDQ-8). Statistical analyses were exploratory. Of 68 randomized patients, 60 (rotigotine, 30; placebo, 30) were evaluable for efficacy. A numerical improvement in pain was observed in favor of rotigotine (Likert pain scale: least-squares mean [95%CI] treatment difference, −0.76 [−1.87 to 0.34]; P = .172), and proportion of responders was 18/30 (60%) rotigotine vs 14/30 (47%) placebo. An ∼2-fold numerical improvement in KPPS domain “fluctuation-related pain” was observed with rotigotine vs placebo. Rotigotine improved PDQ-8 vs placebo (−8.01 [−15.56 to −0.46]; P = .038). These results suggest rotigotine may improve PD-associated pain; a large-scale confirmatory study is needed

Associations between severity of motor function and nonmotor symptoms in Parkinson's disease:A post hoc analysis of the RECOVER study

&lt;b&gt;&lt;i&gt;Background:&lt;/i&gt;&lt;/b&gt; RECOVER (NCT00474058), a double-blind, placebo-controlled trial in patients with Parkinson's disease (PD) and unsatisfactory early-morning motor symptom control, demonstrated significant improvements with rotigotine in early-morning motor function (Unified Parkinson's Disease Rating Scale [UPDRS] III), and nocturnal sleep disturbances (modified Parkinson's Disease Sleep Scale [PDSS-2]), and improvements in nonmotor symptoms (NMS; Non-Motor Symptom Scale [NMSS]). &lt;b&gt;&lt;i&gt;Methods:&lt;/i&gt;&lt;/b&gt; Post hoc analyses investigated the correlation between motor symptom and NMS severity in PD by evaluating associations between UPDRS III and both NMSS and PDSS-2 scores. Categories were defined for UPDRS III, NMSS, and PDSS-2 total scores; analyses were conducted for the full analysis set (n = 267). &lt;b&gt;&lt;i&gt;Results:&lt;/i&gt;&lt;/b&gt; There was a trend toward increasing PDSS-2 and NMSS total and domain scores with increasing UPDRS III category at baseline and end of maintenance (EoM). Pearson correlation coefficients between UPDRS III and both NMSS and PDSS-2 total and domain scores were r = 0.12-0.44 (r&lt;sup&gt;2&lt;/sup&gt; = 0.01-0.19) at baseline, r = 0.05-0.38 (r&lt;sup&gt;2&lt;/sup&gt; = 0.00-0.14) at EoM, and r = -0.02-0.36 (r&lt;sup&gt;2&lt;/sup&gt; = 0.00-0.13) for change from baseline to EoM. &lt;b&gt;&lt;i&gt;Conclusion:&lt;/i&gt;&lt;/b&gt; There was only a small correlation between severity of early-morning motor symptoms and overall burden of NMS and nocturnal sleep disturbances in RECOVER, suggesting that motor symptoms and NMS originate, at least partly, from distinct pathophysiological pathways.</jats:p
