Study to Test the Effectiveness of Controlled-Release OROS® Hydromorphone HCl Compared to Placebo in Patients With Chronic Low Back Pain
A Phase III, Variable-Dose Titration Followed by a Randomized Double-Blind Study of Controlled-Release OROS® Hydromorphone HCl (NMED-1077) Compared to Placebo in Patients With Chronic Low Back Pain
This study will test an experimental drug called OROS® hydromorphone hydrochloride (HCl) (NMED-1077), a once daily opioid analgesic that can relieve pain. A large number of clinical studies have been conducted to test this drug. OROS hydromorphone HCl is currently approved in both the US and Europe to treat chronic pain.
The purpose of this study is to compare OROS hydromorphone to placebo to see if it is safe and efficacious.

- Patients who have demonstrated allergic reactions or hypersensitivity to opioids.
- Patients who have had no bowel movement within three days, or bowel obstruction within 60 days, prior to the screening visit.
Patients with pre-existing severe narrowing of the gastrointestinal tract secondary to:
prior gastrointestinal surgery (e.g., vagotomy, antrectomy, pyloroplasty, gastroplasty, gastrojejunostomy) or gastrointestinal disease resulting in impaired gastrointestinal function (e.g., paralytic ileus, gastroparesis, inflammatory bowel disease, "short gut" syndrome due to adhesions or decreased transit time, past history of peritonitis, cystic fibrosis, chronic intestinal pseudoobstruction, or Meckel diverticulum)
- Patients who have a major psychiatric condition (e.g., schizophrenia, major depression) or who have clinically significant anxiety or depression as defined by a Hospital Anxiety and Depression Scale(HADS) score greater than 10.
- Patients who have received monoamine oxidase (MAO) inhibitors within 14 days prior to the screening visit.
- Patients with clinically significant abnormal laboratory results in clinical chemistry, hematology or urinalysis including serum glutamic-oxaloacetic transaminase/aspartate aminotransferase (AST) or serum glutamic-pyruvic transaminase/alanine aminotransferase (ALT) ≥ 3.0 times the upper limit of the reference range or a serum creatinine ≥ 2.0 mg/dL at screening.
- Patients with a serious or unstable intercurrent illness.
- Patients with a history of uncontrolled seizure disorder.
- Patients with increased intracranial pressure, mental clouding of unknown etiology, coma, or hypotension.
- Patients who have severe asthma, severe chronic obstructive pulmonary disease, or any other disorder that predisposes the patient to carbon dioxide retention or respiratory depression.
- Patients who have taken any investigational drug within 30 days prior to the screening visit or are currently enrolled in another investigational drug study.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline to Week 12 in Mean Pain Intensity
Time Frame: Baseline, Week 12 (or final visit)
|
Participants rate their pain intensity on a numeric rating scale (NRS), where 0=no pain and 10=worst possible pain, in a daily diary.
At Week 12 (or final visit), all measurements during the preceding week are averaged, and the mean change from the mean score at baseline is calculated.
|
Baseline, Week 12 (or final visit)
|
Other Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in Mean Pain Intensity Scores Through the Entire 12-week Treatment Phase
Time Frame: Baseline through Week 12
|
Participants rate their pain on the pain intensity NRS in a daily diary.
At each scheduled visit all measurements during the preceding week are collected, and a mean score for each arm is calculated for each visit.
Mean scores at baseline and each subsequent visit are plotted on a graph for the entire 12-week treatment period, and an area under the curve calculation is used to determine the mean change from baseline for each arm through the entire 12-week treatment phase.
|
Baseline through Week 12
|
Change From Baseline in Mean Patient Global Assessment (PGA) Scores
Time Frame: Baseline through Week 12
|
Change from Baseline in mean PGA scores collected at each visit (at Baseline, Days 1, 4, 8, 11, and Weeks 2, 3, 4, 6, 8, 10, and 12) using the scale: 1=Excellent, 2=Very Good, 3=Good, 4=Fair, and 5=Poor.
The worst possible score is 5.0.
|
Baseline through Week 12
|
Change From Baseline in Mean Scores on the Roland-Morris Disability Questionnaire
Time Frame: Baseline through Week 12
|
Change from baseline in the Roland-Morris Disability Questionnaire (RDQ) score was analyzed for each visit at which the RDQ was administered (Days 1, 8, and Weeks 2, 3, 4, 6, 8, 10, and 12).
This is a 24-item inventory with scores ranging from 0 (highest ability) to 24 (lowest ability).
Higher scores mean more disability.
|
Baseline through Week 12
|
Change From Baseline in Mean Pain Intensity Scores Collected at Scheduled Visits to the Clinic
Time Frame: Baseline through Week 12
|
Participants rate their pain on the pain intensity NRS at each scheduled visit (Baseline, Days 1, 4, 8, 11, and Weeks 2, 3, 4, 6, 8, 10, and 12), and a mean score is calculated.
|
Baseline through Week 12
|
Time to Treatment Failure
Time Frame: within 12 weeks
|
Time to treatment failure is the median number of days from baseline until the earliest day on which the patient's data indicated treatment failure.
|
within 12 weeks
