Rotigotine Restless Legs Syndrome Dose Finding Trial

September 24, 2014 updated by: UCB Pharma

Multi-center, Double-blind, Randomized, Placebo-controlled, Six-arm, Parallel-group, Dose-finding Trial to Determine Efficacy, Safety and Tolerability of Five Different Transdermal Doses of Rotigotine in Subjects With Idiopathic Restless Leg Syndrome

The objective of this trial is to demonstrate clinical efficacy of four different dosages of SPM 962 1.125 mg, 2.25 mg, 4.5 mg and 6.75 mg (corresponding to 2.5 cm2, 5 cm2, 10 cm2 and 15 cm2 patch size respectively) in RLS subjects. It is anticipated that rotigotine (SPM 936) will be more effective than placebo. The tolerability and safety of rotigotine will be assessed.

Description

Inclusion Criteria:

  • Idiopathic Restless Leg Syndrome
  • Subject has responded previously, according to medical history information, to L-Dopa therapy and/or treatment with a dopamine agonist, if pre-treated

Exclusion Criteria:

  • Secondary restless legs syndrome due to, e.g., renal insufficiency (uremia), iron deficiency anemia, rheumatoid arthritis.
  • Secondary restless legs syndrome associated with previous or concomitant therapy with dopamine D2 receptor antagonists, butyrophenones, metoclopramid, atypical antipsychotics (e.g., olanzapine), tri- and tetracyclic antide-pressants, mianserine, lithium or H2-blockers (e.g., cimetidine), or due to withdrawal from drugs such as anticonvulsants, benzodiazepines, barbitur-ates, and other hypnotics.
  • History of sleep disturbances like sleep apnea syndrome, narcolepsy, myoclonus epilepsy observed during polysomnography (PSG) or explored in subject history.
  • Clinically relevant cardiac dysfunction and/or arrhythmias (e.g., suspected conduction system dysregulations, second or third degree AV block, complete left or right bundle branch block, sick-sinus-syndrome, congestive heart failure Class III or IV by NYHA, myocardial infarction within twelve months prior to enrollment).
  • Clinically relevant renal dysfunction (serum creatinine >2.0 mg/dl)
  • Clinically relevant hepatic dysfunction (total bilirubin >2.0 mg/dl or ALT and/or AST greater than two times the upper limit of the reference range).
  • QTc-interval in resting ECG > 450 msec in males and > 470 msec in females.
  • History of symptomatic orthostatic hypotension within 28 days prior to screening visit (Visit 1), or a systolic blood pressure (SBP) less than 105mmHg at trial entry.
