Summary
This trial aims to understand how CBD, a cannabis compound, interacts with tacrolimus, a drug used by organ transplant patients to prevent rejection. Researchers will study these interactions to see if CBD affects the safety and effectiveness of tacrolimus. Tacrolimus is a strong medication used to prevent organ rejection in transplant patients, with precise dosing requirements. The goal is to help doctors adjust doses of both substances to improve patient health and long-term treatment success.
Who is the study for?
This trial is for adults aged 18-65 with either healthy kidneys or chronic kidney disease, not on dialysis. Participants must avoid certain medications, supplements, and substances like tobacco and marijuana that affect the study drugs' metabolism for two weeks before and during the study. Pregnant or breastfeeding individuals, those with compromised liver function, a history of drug abuse or intolerance to study drugs are excluded.
What is being tested?
The trial investigates how cannabidiol (Epidiolex) interacts with tacrolimus in people who have received transplants. It aims to find safe dosing levels that could improve health outcomes by studying single doses of each drug alone and together at steady-state conditions.
What are the potential side effects?
Potential side effects may include digestive issues due to Epidiolex; tacrolimus might cause problems such as high blood pressure, shaking hands, kidney problems, headaches, diarrhea, abdominal pain, insomnia or tingling in hands/feet.

Side Effect Profile
Prior Approvals
Other Research
Tacrolimus is a calcineurin inhibitor that works by suppressing the immune system, specifically by inhibiting T-cell activation, which is essential in preventing organ rejection. Cannabidiol, while not a standard treatment for transplant rejection, has shown anti-inflammatory and immunomodulatory effects that could help in reducing inflammation and modulating immune responses.
These mechanisms are vital for transplant rejection patients as they help in maintaining the transplanted organ's function and improving long-term health outcomes by preventing the immune system from attacking the new organ.
