Study to Test the Effectiveness of Controlled-Release OROS® Hydromorphone HCl Compared to Placebo in Patients With Chronic Low Back Pain

This study has been completed.

This study will test an experimental drug called OROS® hydromorphone hydrochloride (HCl), a once daily opioid analgesic that can relieve pain. A large number of clinical studies have been conducted to test this drug. NMED-1077 is still being tested and is not approved by the Food and Drug Administration (FDA) for sale in the United States. OROS® hydromorphone HCl is currently approved in Europe to treat chronic pain.

The purpose of this study is to compare NMED-1077 to placebo to see if NMED-1077 is safe and efficacious.

Condition Intervention Phase
Chronic Low Back Pain
Drug: Drug: OROS® hydromorphone at 4, 8, 16, and 32 mg tablets will be used to provide doses of 12-64mg.
Drug: Oros Hydromorphone
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: 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

Further study details as provided by Mallinckrodt:

Primary Outcome Measures:
  • The primary efficacy variable is the mean change from baseline to week 12 (or last visit) average pain intensity of double-blind treatment phase based on the weekly pain intensity scores obtained from patient diary entry, as compared to placebo. [ Time Frame: 12 weeks ]

Secondary Outcome Measures:
  • Additional analyses on pain intensity. [ Time Frame: 12 weeks ]

Enrollment: 266

Accepts Healthy Volunteers:   No


  1. Patients must have been provided with written consent to participate in the study prior to any study procedures, and must understand that they are free to withdraw from the study at any time.
  2. Patients who can speak, read, write, and understand English, and must be able to read and understand the consent form, complete study-related procedures, and communicate with the study staff.
  3. Male and female patients aged 18-75 years, inclusive.
  4. Documented diagnosis of moderate to severe chronic low back pain that must have been present
  5. Patients who are classified as non-neuropathic (Class 1 and 2) or neuropathic (Class 3, 4, 5 and 6) of LBP based on the Quebec Task Force Classification of Spinal Disorders will be enrolled for this study.
  6. Patients who require daily scheduled opioid analgesics for low back pain for at least 2 months prior to the screening visit.
  7. Patients with a daily opioid requirement of ≥ 60 mg oral morphine equivalent (≥ 12 mg hydromorphone), but ≤ 320 mg morphine (≤ 64 mg hydromorphone) per day within the 2 months prior to the screening visit.
  8. Patients who, in the Investigator's opinion, are on a stable dose (≥ 2 weeks) of all prior analgesics (both opioid and non-opioid) prior to the screening visit.
  9. Female subjects of childbearing potential including those who have had a tubal ligation surgery but excluding those who have not experienced a menstrual period for a minimum of 2 years, must have a negative serum pregnancy test at screening visit, and must consent to utilize a medically acceptable method of contraception throughout the entire study period including the washout period and for 1 week after the study is completed.


  1. Patients with an active diagnosis of fibromyalgia, complex regional pain syndrome (including reflex sympathetic dystrophy or causalgia), acute spinal cord compression, severe or progressive lower extremity weakness or numbness, bowel or bladder dysfunction as a result of cauda equina compression, diabetic amyotrophy, meningitis, diskitis, back pain because of secondary infection or tumor, or pain caused by a confirmed or suspected neoplasm.
  2. Patients who have undergone a surgical procedure for back pain within 6 months prior to the screening visit.
  3. Patients who have had nerve or plexus block, including epidural steroid injections or facet blocks, within 1 month prior to the screening visit.
  4. Patients with any other chronic pain condition that, in the investigator's opinion, would interfere with the assessment of low back pain (e.g., osteoarthritis, rheumatoid arthritis, postherpetic neuralgia, pain associated with diabetic neuropathy, migraine headaches requiring opioid therapy).
  5. Patients who are involved in an active workman's compensation or insurance claim or disability claim or litigation related to back pain.
  6. Patients who have by history used any illicit drugs of abuse, abused opioids or exhibited drug seeking behavior within 5 years prior to the screening visit.

  8. Patients with a positive alcohol or drugs of abuse test
  9. Women who are pregnant (as indicated by a positive result in a serum pregnancy test administered at screening visit), or breast feeding, or planning to breast feed within 30 days prior to the screening visit.
  10. Patients who have demonstrated allergic reactions or hypersensitivity to opioids.
  11. Patients who have had no bowel movement within three days, or bowel obstruction within 60 days, prior to the screening visit.
