The Efficacy of Hemp-containing Cream Versus Placebo in the Treatment of Uremic Pruritus

Thailand60 participantsStarted 2023-09-15

Plain-language summary

Uremic pruritus is a significant burden on hemodialysis patients, affecting approximately 46% of individuals undergoing dialysis. Various mechanisms, including inadequate dialysis, increased uremic toxins, inflammatory cytokines, parathyroid hormone, phosphorus, dry skin, mast cell histamine secretion, and nerve stimulation through μ-opioid receptors and nociceptors, contribute to uremic pruritus. Current treatments include antihistamines, gabapentin, moisturizer creams, and capsaicin creams, with limited success, as only 10% of patients find relief. Cannabinoids were also mentioned in uremic pruritus treatment but are less commonly used and there are no randomised controlled trial. Cannabinoid binding to CB1 and CB2 receptors inhibits mast cell differentiation, aggregation, and histamine release, whereas cannabinoid binding to TRP-iron receptors reduces peripheral nerve activation. Thus, cannabinoid seem to effective in relieving pruritus via various mechanisms. This study aims to assess the effectiveness of a hemp-containing cream in comparison to a placebo for treating uremic pruritus among hemodialysis patients.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
