Impact of Cannabis Oil on Nutrition in Hemodialysis Patients Study (ICON-HP Study)

The study will be performed in two parts: 1) The pharmacokinetic (PK) part and 2) The appetite and nutritional evaluation part. The PK part of study will be conducted in open label manner on 10 end stage kidney disease (ESKD) patients receiving maintenance hemodialysis (MHD) treatment. For the PK part, a starting dose of cannabis oil -1 drop of 3% cannabis oil once a day \[each drop contain 1.2 mg CBD (cannabidiol) and 1.2 mg of ∆9-THC (∆9-tetrahydrocannabinol)\], was judged to be safe for a first-in-MHD patient's administration. Escalation to the next higher dose and any dose adjustments of the next dose levels will be based on safety and tolerability results of the previously administered dose and available PK data of previous dose groups. Once the first dosage proved to be safe, there will be a 2 fold increase from the first dose level (2 drops once a day) to the second dose level. The dose levels will be increased by 2-fold from the previous dose level, until basal hunger and prospective consumption ratings assessed by the visual analogue scale (VAS) will increase at least by 10 mm between screening and the study visits (change-from-baseline) . PK parameters will be evaluated after first dosage administration and after dosage increased. The appetite and nutritional evaluation part of study will be conducted as a 3-month, double-blind, parallel-group, placebo-controlled, single center study. The study population will include 30 ESKD patients receiving MHD treatment with different degrees of protein-energy wasting (PEW) defined as malnutrition-inflammation score (MIS) above 6. A total of 30 subjects will be randomized to treatment with either cannabis oil or matching placebo.
