Post-market Study of Intrathecal Morphine Compared to Conventional Medical Management for Pain Control and Improvement of Opioid-related Side Effects (CONVERT TDD)

This study has been terminated.
(During protocol amendment development, it was determined the changes to the protocol were significant enough to warrent a new study.)

This study compares two different ways to treat pain. The two ways are:

  1. continuing to take current pain medication(s) or
  2. receiving morphine, a pain medication from a drug pump (a system to deliver drug to your body) that is implanted.

None of the procedures or products used in this study are experimental. The length the study will be about 25 weeks (between 5½ to 6½ months). The purpose of this study is to compare pain and opioid side effects between people who get a drug pump and people who do not get a drug pump that will stay on their current pain medication treatment.

Primary Outcome Measures:
  • Clinical Success [ Time Frame: 3 Month ] [ Designated as safety issue: Yes ]
    Determine the proportion of subjects with clinical success based on changes in pain intensity (Numerical Pain Rating Scale: NPRS) and opioid-related Common Toxicity Criteria for Adverse Events (CTCAE) from the National Cancer Institute (NCI).

Secondary Outcome Measures:
  • Pain Assessment [ Time Frame: 3 Month ] [ Designated as safety issue: No ]
    Compare changes from Baseline to Month 3 between the IT group and CMM group in NPRS

  • Opioid-Related Side Effects [ Time Frame: 3 Month ] [ Designated as safety issue: Yes ]
    Summarize the changes from Baseline to Month 3 between the IT group and CMM group in CTCAE

Other Outcome Measures:
  • Sleep Assessment [ Time Frame: 3 Month ] [ Designated as safety issue: Yes ]

    Compare changes from Baseline to Month 3 between the IT group and CMM group for:

    Sleep and respiratory parameters collected via overnight polysomnography (PSG, sleep study)

Enrollment: 3
Study Start Date: October 2013
Study Completion Date: July 2015
Primary Completion Date: July 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
IT Group (SynchroMed/Intrathecal Morphine Sulfate)
Subjects randomized to the IT group (Intrathecal morphine sulfate/SynchroMed Infusion System) will have a test injection or infusion of intrathecal morphine to check for pain control and make sure there are no negative reactions. If the test is successful, subjects in the IT group will have a pump and spinal catheter implanted. These subjects will stop using all other pain medications and start using only intrathecal morphine for pain control.
Device: SynchroMed Infusion System and Intrathecal Morphine Sulfate
Following a successful intrathecal test of morphine, IT morphine subjects will undergo surgery to implant the drug pump (SynchroMed) and spinal catheter. The pump will deliver morphine directly to the spinal cord for pain control.
Other Names:
  • Implanted drug pump
  • Intrathecal pain medication
  • Infumorph
  • Targeted drug delivery
  • Spinal morphine
  • Intrathecal morphine
No Intervention: Conventional Medical Management
Subjects randomized to the CMM group will continue to use pain medications as prescribed by their doctor. Subjects randomized to CMM will be offered the option of pump implant following completion of the 3-month visit.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Signed and dated Medtronic/IRB approved Informed Consent Form and HIPAA Authorization prior to any study procedures being performed
  • Willing and able to attend visits and comply with the study protocol
  • Willing and able to abstain from alcohol consumption for the study duration
  • At least 18 years of age
  • Male or non-pregnant, non-lactating female
  • Currently receiving </= 300 mg/day morphine equivalent of systemic opioids at screening
  • Used a stable dose of opioids (no change in type or prescribed frequency or dose) for 30 days prior to the Screening as documented in the medical history
  • Used chronic systemic opioids for at least 6 months prior to Screening as documented in medical history

Per investigator's medical assessment and the subject's medical history, the subject is/has:

  • A new candidate for chronic intrathecal drug therapy (including no prior intrathecal/epidural trial for pump infusion therapy)
  • A diagnosis of nonmalignant, chronic intractable pain as documented in the medical history
  • Medically stable and able to undergo surgery for implantation of the SynchroMed Infusion System
  • Completed a psychological evaluation within 6 months prior to Screening

Exclusion Criteria:

  • Psychological or other health conditions, financial, and/or legal concerns (within 3 months prior to Screening) that would interfere with the subject's ability to fulfill the requirements of the protocol as per the investigator's opinion
  • A history of alcohol abuse or any illicit drug use within 2 years prior to Screening
  • A positive urine test for illicit drugs at Screening (Exception: If subject has a physician's prescription for an illicit drug; for example, medical marijuana)
  • Known diagnosis of moderate to severe sleep apnea.
  • Prescribed Continuous Positive Airway Pressure (CPAP), Adaptive Servo-Ventilation (ASV) therapy or an oral appliance prescribed for the treatment of moderate to severe sleep apnea (current or previous history)
  • An active malignancy or has been diagnosed with cancer and has not been in remission for at least 1 year prior to screening
  • An implanted electrical stimulation device(s) or if the subject is expected to require one of these during the course of the study
  • Planned to enroll or is currently enrolled in another investigational drug or investigational medical device study or has participated in an investigational drug or medical device study within 30 days prior to Screening

Prior to Randomization, a subject will be excluded if:

  • Diary does not meet compliance
  • Mean diary-reported 12-hour NPRS < 6 (on 0 to 10 scale, as reported over 5 days)
  • Positive urine test for alcohol at Baseline
  • Negative urine test for opioids at Baseline
  • Baseline sleep study (PSG) with SaO2 <=80% for >= 5 consecutive minutes, and/or an Apnea-Hypopnea Index (AHI) >=15.
