Long-term Efficacy, Safety and Tolerability of Pramipexole in Patients With Idiopathic Moderate to Severe Restless Legs Syndrome (RLS)

2014년 6월 17일 업데이트: Boehringer Ingelheim

A Phase IV Randomised, Double-blind, Placebo-controlled, Dose Titration Trial With Pramipexole (Sifrol, Mirapexin) 0.125-0.75 mg/Day Per os to Investigate the Long-term Efficacy, Safety and Tolerability in Patients With Idiopathic Moderate to Severe Restless Legs Syndrome for 26 Weeks Followed by a 26 Week Open-label Extension Treatment Period

The primary objective of the current study will be the evaluation of long-term efficacy of a 26-weeks treatment with pramipexole in patients with idiopathic moderate to severe Restless Legs Syndrome (RLS) in comparison to placebo.

The key secondary objectives are to assess the effects on clinical global impressions - global improvement (CGI-I) (based on CGI-I responder rate) and on RLS (based on IRLS responder rate) for 26 weeks under pramipexole in comparison to placebo. Further secondary objectives are to investigate the incidence and severity of augmentation and rebound and to assess the effects on patient global impression (PGI) (based on PGI responder rate), on RLS symptoms (based on the RLS-6 scales), on associated mood disturbance (based on item 10 of the IRLS), on pain in limbs (based on a visual analogue scale (VAS)), on quality of life in RLS (based on Johns Hopkins RLS-QoL), on general quality of life Short Form 36 (SF-36) and on safety (based on adverse events (AE) profile) of pramipexole in comparison to placebo.

Diagnosis of Classified Augmentation According to Independent Expert Panel
기간: after at least 4 weeks of treatment
Augmentation is a worsening of RLS symptoms and may manifest as increased severity and the involvement of other extremities or as a shift of RLS symptoms to a time period that is 2 or more hours earlier than was typical of the time of symptom onset during the initial course of beneficial stable treatment or the state before recently starting treatment.

Worsening of RLS Symptoms (by at Least 4 Points in the IRLS Total Score Compared to Baseline) After Treatment Discontinuation
기간: after at least 1 week of treatment discontinuation

Worsening of RLS symptoms, in comparison to baseline, following abrupt treatment discontinuation (for patients with no added RLS therapy after study drug discontinuation).

Assessment of worsening of RLS was based on the IRLS total score assessed 7 ± 1 days after treatment discontinuation (the end of the study or premature discontinuation) compared with that at baseline. Analysis considered the number of patients experiencing a clinically relevant deterioration of ≥4 points in total IRLS score 7 ± 1 days after discontinuation of trial medication compared with baseline.
