Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to assess the efficacy and safety of the Praga formulation in patients suffering from neuropathic pain, particularly those with diabetic polyneuropathy. Participants will be randomly assigned to receive either the Praga formulation, various doses of Pregabalin, or placebo treatments. The study will measure pain relief and safety outcomes over a specified period, utilizing standardized pain assessment scales to evaluate results. The trial is designed to provide robust data on the effectiveness of the Praga formulation compared to existing treatments.
