A Long-Term Extension Trial From Late Phase II of SPM 962 in Patients With Restless Legs Syndrome (RLS)

26 mars 2014 mis à jour par: Otsuka Pharmaceutical Co., Ltd.

An Open-label Long-term Extension Trial From Late Phase II of SPM 962 (243-07-003) in Patients With Restless Legs Syndrome

The aims of the trial are to assess the safety and the efficacy of SPM 962 following once-a-daily transdermal administration within a range of 2.25 to 6.75 mg/day in Japanese patients with restless legs syndrome (RLS) in a multi-center, open-label trial. The maximum treatment period is 53 weeks. The trial is an extension trial from the precedent 6-week, double-blind, randomized, placebo-controlled, parallel-group comparative trial(243-07-003). The trial is also for an exploratory investigation of incidence of augmentation, the most problematic complications in dopaminergic treatment.

Que mesure l'étude ?

Principaux critères de jugement

Mesure des résultats
Description de la mesure
Délai
The Incidence and Severity of Adverse Events (AEs), Vital Signs, and Laboratory Parameters
Délai: Up to 54 weeks

The safety of the long-term SPM 962 treatment was examined based on the incidence and severity of adverse events, vital signs, and laboratory parameters.

AEs of special interest (1-3) are defined as below:

  1. sudden onset of sleep
  2. obsessive-compulsive disorder or impulse-control disorder
  3. hallucination, delusion
Up to 54 weeks
Augmentation
Délai: Up to 53 weeks

Augmentation is the main complication during long-term dopaminergic treatment of restless legs syndrome (RLS) and reflects an overall increase in RLS severity.

Augmentation is clinically significant when at least one of the following occurs:

  1. Change in daily activities and/or behavior (e.g., the patient stops riding in cars in the afternoon) due to augmentation;
  2. Negative impact on the patient's quality of life (sleep, mood, etc.) due to augmentation;
  3. Need to change the treatment dose or the patienｔ needs to take the dose earlier in the day (e.g., dividing the dose);
  4. Adjustments in concomitant medication are made to compensate for augmented RLS symptoms (e.g., an increased intake of analgesics or hypnotics to cover an increase in symptom intensity);
  5. Any other aspect as judged by the evaluator (should be specified).
Up to 53 weeks
Change of the Pittsburgh Sleep Quality Index (PSQI) From Baseline to Each Visit
Délai: Baseline, Up to 53 weeks
PSQI is a scale for assessing severity of sleep disorders. The score ranges from 0 to 21. 0 indicates "no difficulty" and 21 indicates "severe difficulty". A decrease in the scores means improvement.
Baseline, Up to 53 weeks

Description de la mesure
Délai
Change of IRLS Sum Score From the Baseline to Each Visit
Délai: Baseline, Up to 53 weeks

IRLS is a scale for assessing severity of restless legs syndrome symptoms. IRLS consists of ten questions. Each question is scored from 4 for the first (top) answer (usually 'very severe') to 0 for the last answer (usually none).

The sum of the score of each question serves as the scale score. The scale scoring criteria are: Mild (score 1-10); Moderate (score 11-20); Severe (score 21-30); Very severe (score 31-40). A decrease in the scores means improvement.
Baseline, Up to 53 weeks
Efficacy Rate in IRLS Sum Score
Délai: Baseline, Up to 53 weeks
Efficacy rate (percentage of subjects with 50% decrease) (LOCF) in IRLS sum score.
Baseline, Up to 53 weeks
Change of Augmentation Severity Rating Scale (ASRS) Sum Score From Baseline to Each Visit
Délai: Baseline, Up to 52 weeks

ASRS is a scale for assessing severity of augmentation. ASRS consists of 3 items (one item containing 4 sub-items). The sum of the score of each question serves as the scale score (each question score: 0-3, sum score 0-24).

A higher score indicates a greater severity of symptoms. Thus a decrease in the scores means improvement.
Baseline, Up to 52 weeks
Change of Short-Form 36-Item Health Survey (SF-36) From Baseline to Each Visit
Délai: Baseline, Up to 53 weeks
SF-36 is a scale for assessing health status in clinical practice and research. The scores of 36 questions are summarized into 7 sub-scales. In each sub-scale which range is 0-100, a higher score indicates a better health status. Thus a increase in the scores means improvement.
Baseline, Up to 53 weeks
