Is this trial a fit for you?

Likely a good fit

Adults aged 18 or older with chronic painful lumbosacral radiculopathy who have not achieved adequate relief with non-opioid analgesics or for whom such treatments are contraindicated.

Probably not a fit

Patients with contraindications to the study medication, significant cardiovascular disease within the past year, or certain severe psychiatric conditions may not benefit and are excluded.

What this trial studies

This randomized, blinded trial compares VER-01 to placebo in adults with chronic painful lumbosacral radiculopathy who have not achieved adequate pain relief with optimized non-opioid analgesics. Participants will receive VER-01 or placebo and will be monitored for safety and changes in pain and function. The study involves scheduled visits and the use of an electronic diary to capture outcomes. Eligible participants must consent, be willing to adhere to the treatment plan, and have no excluded cardiovascular or severe psychiatric conditions. The trial is conducted at several sites in the United States and is sponsored by Vertanical GmbH.

Why it matters

Potential benefit: If successful, VER-01 could provide meaningful pain relief and improved function for people with chronic painful lumbosacral radiculopathy.

How similar studies have gone: Previous similar approaches have shown mixed results; this trial aims to provide clearer evidence for VER-01 in this condition.
