Butrans for Treatment of Restless Legs Syndrome

NCT02138357 | Withdrawn Phase 4

• 1 other identifier: 2013D004946
• Study Type: interventional
• Target: N/A

Brief Summary

The primary objective of the study is to determine whether Butrans Transdermal System (BTDS) reduces RLS symptom severity in patients with moderate to severe idiopathic RLS who are naïve to opiate treatment. The secondary objective of the study is to investigate the effects of BTDS on mood, sleep, and quality of life. The study will consist of nine visits. Depending on the need for medication titration, there may also be two scheduled telephone contacts. Visit 1: This is a screening visit to determine study eligibility. Eligible subjects who choose to participate must undergo medication washout as described in the detailed protocol between visits 1 and 2. Treatment period #1 (Visits 2 - 5; day 0 - 28): Baseline measures will be recorded and subjects randomized to treatment order at visit 2 (day 0). Study medication as well as rescue medication (l-dopa, a non-blinded active treatment to be used within a limited dose range as described in the detailed protocol) will be dispensed. Subjects will begin treatment period #1 immediately after this. The study medication will be titrated within the allowed range according to subject's reported symptoms during visit 3 (day 7), visit 4 (day 14), telephone contact (day 21). Visit 5 will occur on day 28 and will include assessment of outcome measures for the first treatment period. Visit 5 will also mark the beginning of the second treatment period. Treatment period #2 (Visits 6 - 8; day 28 - 56): Procedures will be similar to those described above during treatment period #1. Visit 8 will mark the end of the second treatment period during which outcome measures will be ascertained. Follow up visit (Visit 9; day 70): This will be a safety follow-up visit approximately two weeks after visit 8 for review of adverse events.

Outcome Measures

Primary Outcomes (1)

• The International Restless Legs Scale (IRLS)

  The primary endpoint will be the within-subjects difference in IRLS between BTDS and placebo treatment, measured at visits 5 and 8. This comparison will be made with a fixed effects model in SAS, using PROC MIXED with a repeated statement (baseline, BTDS, placebo) to account for intra-subject correlation. Sequence, treatment, and treatment by sequence interactionterms will be included as fixed effects.

  Within subjects IRLS score change after 4 weeks on placebo vs 4 weeks on BTDS

Secondary Outcomes (1)

• Clinical Global Impression of Improvement

  Evaluated after 4 weeks on placebo and again after 4 weeks on BTDS or vice versa

Other Outcomes (3)

• MOS Sleep Scales

  Evaluated after 4 weeks on placebo and again after 4 weeks on BTDS or vice versa

• Profile of Mood States (POMS)

  Evaluated after 4 weeks on placebo and again after 4 weeks on BTDS or vice versa

• RLS-QLI

  Evaluated after 4 weeks on placebo and again after 4 weeks on BTDS or vice versa

Study Arms (2)

Placebo Patch

PLACEBO COMPARATOR

The Placebo is in the form of a patch. We will be using placebo patches labeled 5mcg/hour, 10mcg/hour, and 20mcg/hour that will be changed every 7 days. Each subject will participate in this arm of the study for four weeks.

Drug: buprenorphine transdermal delivery system (BTDS); Drug: Placebo for BTDS patch

Eligibility Criteria

• Age: 25 Years - 75 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Subject has a diagnosis of RLS, defined by International Restless Legs Study Group (IRLS) essential criteria:
• An urge to move the legs, usually accompanied or caused by uncomfortable and unpleasant sensations in the legs.
• The urge to move or unpleasant sensations begin or worsen during periods of rest or inactivity such as lying down or sitting.
• The urge to move or unpleasant sensations are partially or totally relieved by movement, such as walking or stretching, at least as long as the activity continues.
• The urge to move or unpleasant sensations are worse in the evening or night than during the day or only occur in the evening or night.
• Subject has moderate to severe RLS symptoms,defined as an International Restless Legs Scale (IRLS) score greater than or equal to15 at the baseline visit (visit 2).
• Subject has RLS symptoms that, in the opinion of the investigator, require round-the-clock treatment.
• Subject speaks and reads English.
• Subject is able to provide informed consent.
• Subject is age ≥25 and ≤75.
• Subject has BMI ≥18 and ≤35
• Subject is naïve to opioid treatment, defined as subjects not having received ≥5 mg oxycodone in the past 14 days and no history of daily use of ≥5 mg oxycodone equivalents in the past 3 months.
• If subject is currently being treated for RLS, s/he must have an inadequate response to or be intolerant of current, non-opioid regimen.
• If subject is not currently being treated for RLS, s/he must have a contraindication to or a history of intolerance to non-opioid treatment options for RLS, concerns about side effects of such options, or a preference for non-oral medication.
• If subject is currently being treated with a medication for RLS, a washout period of at least 3 days will be required (or 5 half-lives for longer-acting agents).

You may not qualify if:

• Lifetime history of DSM-IVopiod, alcohol, or other substance abuse.
• History of opioid treatment for RLS with inadequate response
• Positive urine toxicology screen at visit 1.
• Another chronic pain syndrome that would, in the opinion of the investigator, interfere with evaluation of RLS symptoms or the response to the study medication.
• Plan to undergo a procedure that may require short or long-term opiates for pain control during the course of the trial.
• History of severe mental illness.
• Women who are pregnant, lactating, or planning to become pregnant.
• Shift work or other commitments that do not allow for regular sleep at night.
• Known hypersensitivity or intolerance to opioids.
• History of Long QT Syndrome or an immediate family member with this condition, or known prolongation of QTc interval.
• QTc interval prolongation \>500 ms on screening EKG at Visit 1.
• History of malignant melanoma.
• Current use of monoamine oxidase inhibitors.
• Prior or current clinically significant impulse control disorder, as determined by clinical interview and the Modified Minnesota Impulse Disorders Interview at Visit 1.8
• Untreated severe sleep apnea, defined as AHI \>30.
