Safety and Activity Study of Intrathecally Administered Ziconotide for Neuropathic Pain in Patients With Cancer

Phase 2

Active, not recruiting

• Conditions: Pain; Neuropathic Pain; Intractable Pain; Cancer
• Interventions: Drug: ziconotide

• Registration Number: NCT00996983
• Lead Sponsor: National Cancer Institute, Naples

Brief Summary

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.

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.
