Trial Outcomes & Findings for Clinical Study to Evaluate Cannabidiol Liver Enzyme Elevations and Drug Interactions (NCT NCT06192589)

NCT ID: NCT06192589

Last Updated: 2025-07-31

Results Overview

The upper limit of normal (ULN), based on consensus criteria, for the liver transaminase ALT (Alanine transaminase) is defined as 33 U/L for males and 25 U/L for females. An ALT evaluation three times the ULN for males would be 99 U/L and 75 U/L for females.

PRIMARY outcome

Timeframe: Days 1 through 35

Population: The liver safety analysis population will include all subjects who receive at least 1 dose of the study drug and have at least one on-treatment liver and hematology lab assessment. Subjects in the liver safety analysis population will be used for the planned primary, secondary, and exploratory analyses related to liver enzyme elevations and liver events. Results will be reported as percentages with a 95% confidence interval (CI) based on a Kaplan-Meier analysis.

The upper limit of normal (ULN), based on consensus criteria, for the liver transaminase ALT (Alanine transaminase) is defined as 33 U/L for males and 25 U/L for females. An ALT evaluation three times the ULN for males would be 99 U/L and 75 U/L for females.

Population: All subjects who receive at least one dose of study drug and have at least one on-treatment PK sample collected. One subject was removed from the analysis due to a protocol violation.

AUC will be determined by collecting pharmacokinetic (PK) blood samples and calculated using noncompartmental analysis. 13 PK samples will be obtained with each citalopram dose for a total number of 26 PK samples per citalopram cohort participant. The outcome measure reported will be the geometric mean ratio for citalopram alone compared to citalopram after 7 days of CBD dosing.

SECONDARY outcome

Timeframe: Days 1 and 29

Population: Analyses include all participants with time-matched samples at day 1 and 29. Participants without day 29 samples (e.g., discontinued treatment prior to day 29) were excluded from the analysis.

Endocrine assessments for free T4 will be obtained through blood samples. A linear mixed effect model will be utilized to obtain least squares means for each treatment group.

Cannabidiol (Part 1)
n=139 Participants
Subjects in this arm will receive oral solution cannabidiol at a dosage of 2.5 mg/kg twice a day, for a total of 5 mg/kg cannabidiol daily for 28 days. Cannabidiol: Cannabidiol (Epidiolex) will be administered orally 2.5 mg/kg twice daily (5 mg/kg/day) for 28 days in Part 1 and for 9 days (morphine cohort) or 12 days (citalopram cohort) in Part 2.
Placebo (Part 1)
n=47 Participants
Subjects in this arm will receive oral solution placebo twice a day for 28 days. Placebo: Placebo will be administered orally twice daily for 28 days in Part 1
Part 2: Morphine and Multiple Doses of Cannabidiol
Subjects in this arm will receive morphine (15 mg) on Day 1 (baseline), Day 4, and Day 11 (with CBD). Oral solution cannabidiol at a dosage of 2.5 mg/kg twice a day (5 mg/kg cannabidiol daily) for 9 days (Day 4-12). Reported data is for morphine exposures from morphine following multiple doses of cannabidiol (Day 11-12).

SECONDARY outcome

Timeframe: 0, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 6, 12, 24, and 48 hours after each morphine dose (Days 1, 4, and 11)

Population: All subjects who receive at least one dose of study drug and have at least one on-treatment PK sample collected. For morphine and its metabolites, number of subjects is 20 for morphine alone and morphine with a single dose of CBD. For morphine with multiple doses of CBD, the sample size is 18 as two subjects discontinued from the study.

AUC will be determined by collecting pharmacokinetic (PK) blood samples and calculated using noncompartmental analysis.13 PK samples will be obtained with each morphine dose for a total number of 39 PK samples per morphine cohort participant. The outcome measure reported will be the geometric mean ratio for morphine-3-glucuronide (M3G) alone compared to morphine-3-glucuronide (M3G) after 7 days of CBD dosing.
