Efficacy and Safety of VER-01 in the Treatment of Participants With Chronic Painful Lumbosacral Radiculopathy
(EXPAND)
What this study is about
The aim of the trial is to prove the effectiveness and safety of VER-01 compared to placebo in patients with chronic painful lumbosacral radiculopathy (PLSR) for whom drug treatment is indicated and previous optimized treatments with non-opioid analgesics have not led to sufficient pain relief or were unsuitable due to contraindications or intolerance.

Interventions
DRUG
VER-01
Standardized soft extract from Cannabis sativa DKJ127 L., cannabis flos (Cannabis flower), corresponding to 19 mg Δ9-Tetrahydrocannabinol (THC) per ml drug product
OTHER
Placebo
Comparator without active ingredient
Primary outcome measures
Efficacy based on pain reduction
Time frame: From Baseline to Treatment Week 12
The primary endpoint is the absolute change in mean leg pain intensity in the index leg measured on an 11-point numerical rating scale (NRS) at Treatment Week 12 compared to Baseline.
Who can participate

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
