Neuropathic pain is difficult to control because it is only partially sensitive to opioid analgesics, and requires the addition of other therapies such as antidepressants and epileptics. Ziconotide is a drug that is used to treat neuropathic pain in patients who have had inadequate pain control with prior combination of medicines.

Secondary Outcome Measures:
  • toxicity [ Time Frame: daily during drug titration, weekly thereafter ]
  • duration of analgesic response [ Time Frame: weekly ]

Estimated Enrollment: 16
Study Start Date: September 2009
Estimated Study Completion Date: July 2017
Estimated Primary Completion Date: July 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: A Drug: ziconotide
intrathecal ziconotide starting at 2.4 micrograms/day, with titration daily to achieve adequate pain control up to maximum dose of 21.6 micrograms/day

Detailed Description:
The purpose of this study is to evaluate the effects and the tolerability of intrathecal ziconotide in cancer patients suffering from severe neuropathic pain not controlled by previous therapies.
