Efficacy and Tolerability of AP707 in Patients With Chronic Pain Due to Diabetic Polyneuropathy

• Status: Recruiting
• Trial end date: 2024-12-31
• Target enrollment: 0
• Participant gender: All

Summary

Over the last years a rising medical need for treatment of chronic pain was identified. Based on previous findings indicating the pain modulating effects of cannabinoids in chronic pain disorders, this clinical trial investigates the efficacy and tolerability of the THC-focused nano endocannabinoid system modulator AP707 in patients with pain disorders due to diabetic polyneuropathy. Patients receive AP707 or placebo over the course of 14 weeks as an add-on to the standard of care. Changes in pain intensity, quality of life and sleep and others measures are monitored through different scales to assess the efficacy of AP707 in patients with chronic pain due to diabetic polyneuropathy.
