Long-term, open-label, safety study of once-daily ropinirole extended/prolonged release in early and advanced Parkinson's disease.

Long-term safety of once-daily ropinirole extended/prolonged release (ropinirole XL/PR) was evaluated in subjects with early and advanced Parkinson's disease (PD) in this study, 101468/248. Subjects (n = 419) who completed one of three prior studies evaluating ropinirole XL/PR for the treatment of PD were enrolled in this open-label, multicenter, extension study, and were to be followed for up to 73 months. Ropinirole XL/PR was titrated/continued, and adjusted as appropriate during the maintenance phase (maximum 24 mg/d). Levodopa (L-dopa) and other nondopamine agonist PD medications were permitted. Safety outcomes that were investigated included frequency of adverse events (AEs). Subjects' preference regarding once daily versus three times daily study medication regimens was also investigated in a subset of the study population. The median duration of ropinirole XL/PR exposure was 1275 d. Most subjects (87%) reported at least one AE, with the most common (≥ 10%) AEs being, back pain (14%), hallucinations (13%), somnolence (11%) and peripheral edema (11%). Twenty-five percent of subjects discontinued the study prematurely due to an AE during the treatment period. Long-term treatment with ropinirole XL/PR was not associated with any new or unexpected safety concerns in patients with early and advanced PD, and a majority of subjects preferred the once-daily dosing regimen.

Association Between the Affordable Care Act and Emergency Department Visits for Psychiatric Disease.

INTRODUCTION: Emergency department (ED) utilization for psychiatric disease is increasing, and a lack of health insurance has been identified as a potential cause of preventable or avoidable ED use. Through the Affordable Care Act (ACA), more uninsured individuals gained health insurance; however, the effects of increased health insurance coverage on ED utilization for psychiatric disease have not been examined. METHODS: We performed a longitudinal, cross-sectional analysis of data from the Nationwide Emergency Department Sample, the largest all-payer ED database in the US, which contains data on over 25 million ED visits each year. We examined ED utilization for psychiatric disease as the primary reason for visit among adults aged 18-64. We compared the proportion of ED visits with a psychiatric diagnosis during post-ACA years (2011-2016) to pre-ACA (2009) using logistic regression adjusted for age, gender, payer, and hospital region. RESULTS: The proportion of ED visits with psychiatric diagnosis increased from pre-ACA (4.9%) to post-ACA years (ranging from 5.0-5.5%). There was a significant difference in the proportion of ED visits with a psychiatric diagnosis when comparing each post-ACA year with pre-ACA, with adjusted odds ratios ranging from 1.01-1.09. Among ED visits with a psychiatric diagnosis, the most common age group was 26-49 years, and patients were more likely to be male than female and to have visited urban rather than rural hospitals. During post-ACA years (2014-2016), private and uninsured payers decreased, Medicaid payers increased, and Medicare payers increased in 2014 and decreased in 2015-2016 compared to pre-ACA. CONCLUSION: With the ACA more people gained health insurance, yet ED visits for psychiatric disease continued to increase. These results suggest that increasing access to health insurance alone is not sufficient to reduce ED utilization for patients with a psychiatric disease.

Systematic evaluation of augmentation during treatment with ropinirole in restless legs syndrome (Willis-Ekbom disease): results from a prospective, multicenter study over 66 weeks.

The purpose of this study was to evaluate the incidence of augmentation over 66 weeks of treatment with ropinirole in patients with primary restless legs syndrome (RLS). Augmentation is the main complication of long-term dopaminergic treatment of RLS. Despite widespread use of ropinirole in RLS, no studies have prospectively and systematically assessed the incidence of augmentation with its use. The study consisted of 26 weeks of double-blind flexible-dose treatment with ropinirole or placebo, followed by 40 weeks of open-label ropinirole treatment.. Patients had no previous history of augmentation. Potential cases of augmentation were identified with the Structured Interview for the Diagnosis of Augmentation and the Augmentation Severity Rating Scale and through reporting of adverse events. Cases were blindly evaluated by an expert panel using the NIH diagnostic criteria for augmentation. Four hundred and four patients participated in the double-blind study and 269 in the open-label phase, with a discontinuation rate of 42%. IRLS baseline scores improved at the end of the double-blind (DB) phase (mean ± SE) by -15.9 ± 0.76 for ropinirole, by -13.4 ± 0.77 for placebo (P < .05) and by -20.4 ± 0.55 during the open-label phase. The incidence rates of augmentation were 3.5% for ropinirole and <1% for placebo during the DB phase and 3% during the open-label phase. Clinically significant augmentation occurred in 3%, <1%, and 2%, respectively. Discontinuation of treatment occurred in 50% of all patients (7 of 14) with augmentation. The incidence of augmentation was 3.1% higher with ropinirole than with placebo. New patients with first episodes of augmentation continued to cumulate at a stable rate over the duration of this study.

Long-term, open-label study of once-daily ropinirole prolonged release in early Parkinson's disease.

Long-term safety and efficacy of once-daily ropinirole prolonged release (PR) were evaluated in subjects with early Parkinson's disease (PD). Subjects (n = 83) who completed one of two studies were enrolled in this open-label, multicenter, extension study, and followed for up to 78 months. Ropinirole PR was titrated/continued, and adjusted as appropriate during the maintenance phase (maximum 24 mg/day). L-dopa and other non-dopamine agonist PD medications were permitted. Safety outcomes included adverse events (AEs). Efficacy outcomes included Unified Parkinson's Disease Rating Scale (UPDRS) II and III scores, and Clinical Global Impression-Severity (CGI-S) and Improvement (CGI-I) scores. The median duration of ropinirole PR exposure was 1,069 days. Most subjects (97.6%) reported at least one AE, most commonly (≥ 30%) nausea (42.2%), dizziness (41.0%), peripheral edema (38.6%), back pain (33.7%), and headache (31.3%). Seventeen (20.5%) subjects discontinued due to an AE. UPDRS and CGI scores indicated that the clinical status of subjects was maintained throughout the treatment period. In patients with early PD, long-term treatment with once-daily ropinirole PR was not associated with any new safety concerns, and was effective in maintaining clinical status. These results support the extended use of ropinirole PR for treatment of PD.

Seasonal affective disorder and its prevention by anticipatory treatment with bupropion XL.

BACKGROUND: Seasonal affective disorder (SAD) can cause significant distress and impairment. No antidepressant studies have previously attempted to prevent the onset of autumn-winter depression. METHODS: Three prospective, randomized, placebo-controlled prevention trials were conducted on 1042 SAD patients, enrolled in autumn and treated while still well, across the northern US and Canada. Patients received either bupropion XL 150-300 mg or placebo daily by mouth from enrollment until spring and were then followed off medications for 8 additional weeks. Primary efficacy variables were end-of-treatment depression-free rates and survival distributions of depressive recurrence. RESULTS: Despite a reported average of 13 previous seasonal depressive episodes, almost 60% of patients had never previously been treated for depression. Major depression recurrence rates during the three studies for bupropion XL and placebo groups were 19% versus 30% (p = 0.026), 13% versus 21% (p = 0.049), and 16% versus 31%; yielding a relative risk reduction across the three studies of 44% for patients taking bupropion XL. Survival analyses for depression onset also favored bupropion XL over placebo (p = .081, .057, and <.001). CONCLUSIONS: It is possible to prevent recurrence of seasonal major depressive episodes by beginning bupropion treatment early in the season while patients are still well.

Ropinirole in patients with restless legs syndrome and baseline IRLS total scores ≥ 24: efficacy and tolerability in a 26-week, double-blind, parallel-group, placebo-controlled study followed by a 40-week open-label extension.

BACKGROUND: As with studies of other dopamine agonists, previously reported studies of ropinirole in restless legs syndrome (RLS) recruited patients with baseline International Restless Legs Scale (IRLS) total scores ≥ 15. The reported pooled analyses of clinical trials data suggest benefits of ropinirole in patients with IRLS total scores ≥ 24, but the effects of ropinirole have not been prospectively evaluated in this patient population. OBJECTIVE: The goal of this study was to evaluate the efficacy and tolerability of ropinirole in patients with RLS and baseline IRLS total scores ≥ 24. This study was conducted in part to fulfill a postlicensing commitment between the maker of ropinirole and the European Union's Committee for Medicinal Products for Human Use. METHODS: The protocol for this study comprised a randomized, double-blind, placebo-controlled, parallel-group, 26-week phase during which adults with baseline IRLS total scores ≥ 24 received a ropinirole dose from 0.25 to 4 mg (n = 197) or placebo (n = 207) followed by a 40-week, open-label phase during which all patients (n = 269) received ropinirole. The primary efficacy end point was the change from baseline in the IRLS total score at week 12. Tolerability measures included the incidence of adverse events, augmentation, and early morning rebound. Due to the possibility of a treatment-by-center group interaction (P = 0.04) in the IRLS analysis, further efficacy exploratory analyses were performed to assess the impact of the interaction on the overall assessment of efficacy. RESULTS: Demographic characteristics were comparable between groups (mean [SD] age: placebo, 56.1 [11.38] years; ropinirole, 56.5 [11.92] years; 63% female in both groups). All of the patients in the ropinirole group were white; 99% of the placebo group was white. Ropinirole was significantly better than placebo for change from baseline in the IRLS total score during both short- and long-term treatment, with mean treatment differences of -2.1 (P = 0.039) and -2.5 (P = 0.023) for weeks 12 and 26, respectively. A statistically significant treatment by center group interaction was observed (P = 0.040) for the change from baseline in IRLS total score, indicating variation of treatment effects among center groups; however, all center groups showed an improvement from baseline at both week 12 and week 26 for the ropinirole immediate-release group and the placebo group. The incidences of augmentation and early morning rebound were ≤ 4% for ropinirole. The adverse event profile of ropinirole was consistent with that reported in previous clinical trials. CONCLUSIONS: In this subset of patients with RLS and a baseline IRLS total score ≥ 24, ropinirole was effective and well tolerated compared with placebo. The incidence of augmentation and early morning rebound in this study was low.

Patient- and physician-rated measures demonstrate the effectiveness of ropinirole in the treatment of restless legs syndrome.

OBJECTIVES: To investigate the effect of twice-daily ropinirole in patients with early evening restless legs syndrome (RLS) symptoms, particularly focusing on the relationship of patient- and physician-rated assessment of treatment outcomes. METHODS: In this multicenter, double-blind, randomized, 12-week, flexible-dose study, patients with primary RLS, with symptom onset no earlier than 5 PM and a baseline International Restless Legs Syndrome Study Group Rating Scale (IRLS) total score > or = 20 received ropinirole 0.5 to 6.0 mg/d twice daily in equally divided doses, or placebo. First dose was 1 hour before the usual onset of symptoms; second dose was 3 to 8 hours after the first. Primary end point: change from baseline in IRLS total score at week 12 last observation carried forward (LOCF). Key secondary end points: proportion of responders (rated "very much improved" or "much improved") on the Clinical Global Impression-Improvement and the Patient Global Improvement scales. RESULTS: Improvements in IRLS total score were statistically significantly greater for ropinirole (n = 175), compared with placebo (n = 184) at all assessment points beginning at day 3 through to week 12 LOCF (P < 0.001). A statistically significantly greater proportion of patients were classified as responders on the Clinical Global Impression-Improvement scale at all assessment points from day 3 through week 12 LOCF (P < 0.001) and on the Patient Global Improvement scale at all assessment points from day 1 (P = 0.013) through day 7 LOCF (P < or = 0.05 for days 2-7 LOCF) and at week 12 LOCF (P < 0.001). CONCLUSIONS: Ropinirole is associated with consistent early and sustained improvements in the symptoms of RLS, as rated by patients and physicians.
