Treatment Study
Summary
This is a study focused on treating neuropathic pain, a type of pain caused by damage to the nerves. It's specifically designed for individuals who have recently participated in a previous study (NeurogesX Study C111) and received treatment with a medication called NGX-4010, or Capsaicin Patch. The goal is to further explore the potential benefits of this treatment for neuropathic pain. In this study, participants will continue to receive the NGX-4010 treatment, which comes in the form of a patch. The study will monitor the effects of the treatment over time to understand its long-term impact on neuropathic pain. It's important to note that as an open-label study, everyone involved knows which treatment is being used.
