Area of Science:

  • Pharmacology
  • Neurology

Background:

  • Elan Pharmaceuticals is developing ziconotide, a neuron-specific N-type calcium channel blocker.
  • Ziconotide is being investigated for the treatment of severe pain and ischemia.

Purpose of the Study:

  • To evaluate the efficacy and safety of ziconotide in patients with intractable pain.
  • To assess the potential of ziconotide in treating ischemia associated with head trauma and stroke.

Main Methods:

  • Pivotal studies involved over 700 patients receiving intrathecal ziconotide for intractable pain.
  • Phase III trials for ischemia are ongoing.
  • Development of orally available nonpeptide analogs is also underway.

Main Results:

  • Ziconotide showed a significant reduction in pain compared to placebo in pivotal studies.
  • The drug was safe and well-tolerated in patients, including those who failed morphine therapy.
  • Treatment was effective over periods as long as 3 years.

Conclusions:

  • Ziconotide is a promising treatment for intractable pain, offering significant relief and a favorable safety profile.
  • Further research is ongoing for its application in ischemia-related conditions.
