Study Overview: This research is testing a new drug, **RTA 901**, for helping people with **Diabetic Peripheral Neuropathic Pain (DPNP)**. DPNP is a type of pain some people with diabetes feel in their legs and feet. The study will check if RTA 901 is safe and if it works to reduce the pain. A **placebo**, which is a fake treatment that looks like the real one but has no effect, will be used for comparison.
Study Structure: The study is divided into two parts, each lasting about 20 weeks. It involves different phases: Screening (up to 2 weeks), Run-in (2 weeks), Treatment (12 weeks), and Follow-up (4 weeks). During the study, participants will be assigned randomly to receive one of two doses of RTA 901 or a placebo.
Participation Details:
- Participants should have type 1 or type 2 diabetes for at least a year and suffer from DPNP.
- The entire study takes about 20 weeks, including several visits and assessments.
- Participants must meet specific health criteria and should not have other conditions affecting pain.
