Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults over 18 years old with a clinical diagnosis of sickle cell disease and chronic pain.
✕Probably not a fit
Patients with a history of psychotic episodes or those who are currently pregnant or nursing may not benefit from this study.
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 investigates the use of dronabinol, a cannabinoid, as a palliative treatment for adults suffering from sickle cell disease (SCD) and chronic pain. It is a randomized, double-blind study that aims to assess the effectiveness of dronabinol in improving pain and quality of life, as well as its impact on inflammation markers compared to a placebo. Participants will be monitored for safety and tolerability throughout the study duration.
Why it matters
Potential benefit: If successful, this treatment could significantly alleviate pain and improve the quality of life for patients with sickle cell disease.
How similar studies have gone: Other studies have explored cannabinoid treatments for pain management, showing promising results, but this specific approach is still being evaluated.
