Primary Outcome Measures:
  • Number Who Reached a Safe Dose [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]
    The number of patients who reached a safe and well tolerated dose of d-methadone


Enrollment: 10
Study Start Date: October 2004
Study Completion Date: July 2008
Primary Completion Date: July 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Phase I, Group
This is an open label dose-ranging trial. The first cohort of 8 patients will receive 40mg of d-methadone every 12 hours.
Drug: d-Methadone
8 subjects to receive 40 mg d-Methadone twice a day
Experimental: Phase II, Group I
patients receiving around the clock opioid therapy-No patients were accrued to this group
Drug: D-methadone
After randomization, patients will take the study drug or placebo for 12 days and then they will cross-over to the opposite arm for another 12 days. The study will end on day 24.
Experimental: Phase II, Group II
patients not receiving around the clock opioid therapy.No patients were accrued to this group
Drug: placebo
After randomization, patients will take the study drug or placebo for 12 days and then they will cross-over to the opposite arm for another 12 days. The study will end on day 24.

Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

Phase I and Phase II portions of the study:

  • 18 years of age or older
  • Chronic pain with average 24 hour intensity rated at least 3 on a verbal numerical scale from 0-10 during the 24 hours prior to study entry.
  • Give informed consent to participate in this study.
  • Karnofsky Performance Score (KPS) >= to 80
  • Negative urine pregnancy test, verified by the study nurse, at study entry (for women of child-bearing potential). Patients must also use a medically approved contraceptive method during the study period.

Phase I only:

  • Responsible companion living with patient during study.

Phase II only:

  • Group 1 -- Patients must be taking chronic opioid therapy (long acting morphine, long acting oxycodone, transdermal fentanyl) at a stable dose for a minimum of four days. The dose of as needed short acting opioid does not need to be stable.
  • Group 2 -- Patients must not be receiving opioids and must have cancer related neuropathic pain secondary to post-chemotherapy peripheral neuropathy, post-radiation and/or post surgical plexopathy, radiculopathy or neuropathy, or post- herpetic neuralgia.

Exclusion Criteria:

Phase I and Phase II:

  • Known hypersensitivity to methadone
  • Patient taking methadone or with a history of methadone treatment within one month of study enrollment.
  • Patient that requires changes in the dose of one of the following medications within 2 weeks of study enrollment:

    • Abacavir,
    • Benzodiazepines,
    • Carbamazepine,
    • Efavirenz,
    • Fluconazole,
    • Fluvoxamine,
    • FOS amprenavir,
    • Fosphenytoin,
    • Naltrexone,
    • Nelfinavir,
    • Nevirapine,
    • Phenytoin,
    • Rifampin,
    • Rifapentine,
    • Risperidone,
    • Ritonavir,
    • St. John's Wort,
    • Zidovudine
  • Hepatic function tests (SGOT, alkaline phosphatase, bilirubin) greater than 2 times the upper limit of normal or creatinine greater than 1.4 within 30 days of study entry.
  • Neurologic or psychiatric disease sufficient, in the investigator's opinion, to compromise data collection.
  • Women who are pregnant or nursing.
  • Women of childbearing potential who do not agree to use a medically recognized method of contraception during the study period.
