Single Shot Intrathecal Ziconotide for Painful Neuropathy or Myelopathy

Painful Neuropathy Clinical Trial

Official title: A Phase 4, Randomized, Double-blind, Placebo-controlled, Cross-over Clinical Trial of a Single Shot of Intrathecal Ziconotide for the Treatment of Chronic, Medically Refractory Pain From Painful Peripheral Neuropathy or Myelopathy

Status Withdrawn

Clinical Trial Summary

This is a phase 4 study being conducted at the Ohio State University Department of Neurology Multiple Sclerosis Research Program. The purpose of the study is to administer a single shot of intrathecal (injection into the space surrounding the spinal cord via a lumbar puncture or spinal tap) ziconotide as a test dose to patients who have chronic painful myelopathy (pain from spinal cord damage) or painful peripheral neuropathy (pain from nerve damage) that has not responded to other pain medicines.

Clinical Trial Description

Study Hypothesis: We intend to determine if a single shot trial (SST) of intrathecal (IT) ziconotide will temporarily reduce pain in these patients. In the proposed study, patients will receive two injections, one of which is the ziconotide and one which is a placebo. They will be blinded and not know which order they receive the treatment versus placebo. The results of this clinical trial will provide a focused examination of ziconotide efficacy and safety in patients with painful neuropathies or myelopathies that have not been effectively treated with other pain medications. Moreover, the use of a single shot trial (SST) IT injection in the outpatient setting will provide evidence for application of this technique in outpatient neurological clinical practice, thereby improving access to this specific patient population. Ziconotide is currently FDA approved for this indication and route of administration. Therefore, a study design that improves the feasibility of ziconotide trialing specifically in the neurology clinic (that is, single shot administration) is being used in order to ensure its broader use by neurologists who routinely care for neuropathy and myelopathy patients. Information from this study will also inform future studies of predictors for long term efficacy after pump placement. ;
