Arms and Interventions

Arm Intervention/treatment
Experimental: Active
Subjects on hydromorphone hydrochloride for the duration of therapy.
Drug: Hydromorphone Hydrochloride
Subjects who meet criteria for randomization, will be randomized in a 1:1 ratio to either the active arm or control arm.
Other Names:
  • Hydromorphone
  • Opioid
Active Comparator: Titrated off therapy
Subjects on control
Drug: Hydromorphone Hydrochloride
Active Control Based on Dose Reduction


Outcome Measures

Primary Outcome Measures :
  1. Superiority of intrathecal hydromorphone hydrochloride as compared to a control arm. [ Time Frame: 4 weeks ]
    The primary efficacy endpoint is the proportion of subjects who are treatment failures during the double-blind randomized withdrawal period. A subject who experiences an increase of 20 mm or more points on a 100 mm visual analog scale of pain intensity (VASPI), based on a 3-day average, or who experiences intolerable pain that requires intervention, will be considered a treatment failure


Secondary Outcome Measures :
  1. Functionality based on a Brief Pain Inventory [ Time Frame: 18 weeks ]
    Patients ability to function and perform tasks without significant pain based on the brief pain inventory (BPI) scale.

Ages Eligible for Study:   18 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

Subjects must meet all of the following criteria to be included:

  1. Subject must be at least 18 years of age and no more than 75 years old.
  2. Clinically diagnosed with chronic pain for at least a 6-month period.
  3. Subject is presently on intrathecal pain medication and has a SynchroMed II Implantable pump or meets clinical criteria for implantation of a SynchroMed II Implantable pump. Subjects who are naïve to intrathecal therapy, may be enrolled 2-weeks after pump implantation.
  4. Subject agrees to sign a Pain Treatment Agreement (Narcotic Contract) limiting narcotic prescriptions to the study physician.
  5. Subject must be cognitively intact and, in the opinion of the investigator, capable of participation in the trial.
  6. Female subjects of child-bearing potential must agree to use a medically acceptable and effective double-barrier method of birth control.
  7. Subjects with existing SynchroMed II Implantable pumps and are reasonably expected to benefit from intrathecal opioid therapy only.
  8. Subjects who are capable of receiving an MRI with or without contrast or CT myelogram, if required by the study protocol.
  9. Provides written Ethics Committee approved informed consent.
  10. Willing to comply with all study procedures and requirements..

Exclusion Criteria:

Subjects meeting any of the following criteria will be excluded:

  1. Women who are pregnant or are breast-feeding
  2. Subjects who have participated in an investigational drug or device trial within 4 weeks prior to enrollment.
  3. Subject has any known or suspected allergy to hydromorphone or to the materials of the infusion pump or intrathecal catheter.
  4. Subject is scheduled for a pump or catheter replacement within 6 months of their enrollment into the trial.
  5. Subject has a history of dependence and abuse of opioids, stimulants, alcohol, or benzodiazepines, as defined by DSM-IV criteria, within the past year (physical dependence on prescribed opioid analgesics is allowed but abuse of opioids according to DSM-IV is not permitted, i.e. opioid addiction for recreational use).
  6. Subjects who show signs of active systemic infection.
  7. Subjects with a metastatic cancer to the spinal canal or a known central nervous system contraindication to intrathecal therapy.
  8. Subject has a condition requiring diathermy procedures.
  9. Subject has a life expectancy of less than 12 months.
  10. Subject cannot independently comprehend and participate in the required assessments, including responding to the VASPI, Short-form McGill Pain Questionnaire (SF-MPQ), Clinical Opiate Withdrawal Scale (COWS), Subjective Opiate Withdrawal Scale (SOWS), BPI and patient global impression of change (PGIC) measurement tools.
  11. Subject is not considered to be medically or psychologically appropriate for pump implantation.
  12. Subjects who are unable or unwilling to return to all of the required follow-up visits.
  13. Subjects with active implanted devices such as pacemakers, defibrillators, and cochlear implants or other medical device use, if in the opinion of the investigator the device would interfere with the ability to perform an MRI or CT myelogram.
  14. As a result of medical review and physical examination, the Investigator considers the subject unfit for the study.
  15. Pain located above the shoulders in the head or neck region (e.g. trigeminal neuralgia), central pain syndromes or any other condition in which it is judged to be unlikely that the subject would benefit from intrathecal administration of the drug product.
  16. Subjects who have previously been unresponsive to intrathecal hydromorphone therapy.
