Brief summary
This study was conducted to determine the efficacy and safety of GWP42003 compared with placebo by the percentage of participants achieving remission quantified as a Mayo score of 2 or less (with no sub-score \>1) after 10 weeks of treatment.
Detailed description
This study was conducted by GW Research Ltd as a pilot study to determine the efficacy and safety of GWP42003 (50 milligram \[mg\] up to 250 mg twice daily \[BID\]), compared with placebo, as assessed by the percentage of participants achieving remission quantified as a Mayo score of 2 or less (with no sub-score \>1) after 10 weeks of treatment. This was the first study to determine whether the study drug has a positive benefit for participants on their ulcerative colitis symptom control, as well as effects on inflammatory marker cytokines (C reactive protein \[CRP\]), a fecal inflammatory marker (calprotectin), stool frequency, and rectal bleeding. In addition, various inflammatory bowel disease (IBD) questionnaires were implemented in the study to observe further benefits on the study drug, compared with placebo. This study was multi-center, randomized, double-blind, placebo-controlled, and parallel-group. The study consisted of a 7-day baseline period, a 10-week treatment period, and a 1-week follow-up period. Each participant had a Mayo assessment (including endoscopy) conducted to confirm eligibility. Eligible participants were randomized in a 1:1 ratio into the GWP42003 and placebo groups. At the start of the treatment period, participants entered a 2-week dose escalation period to achieve their maximum tolerated dose, up to 250 mg BID in the GWP42003 group. Participants remained at the maximum tolerated dose for the rest of the treatment period.

The total score is made up of 4 sub-scores (assessed using a 0 to 3 scale). The sub-scores are graded as follows: Stool Frequency: 0 = Normal number of stools, 1 = 1 to 2 stools more than normal, 2 = 3 to 4 stools more than normal, 3 = 5 or more stools more than normal; Rectal Bleeding: 0 = No blood seen, 1 = Streaks of blood with stool less than half the time, 2 = Obvious blood with stool most of the time or more, 3 = Blood alone passes; Findings on Endoscopy: 0 = Normal or inactive disease, 1 = Mild disease (erythema, decreased vascular pattern, mild friability), 2 = Moderate disease (marked erythema, lack of vascular pattern, friability, erosions), 3 = Severe disease (spontaneous bleeding, ulceration); PGAS: 0 = none, 1 = mild, 2 = moderate and 3 = severe. A negative change from Baseline indicates that symptoms improved.
Time frame: Baseline to EOT (10 weeks) or ET
Population: ITT analysis set: all participants who were randomized and received at least 1 dose of study drug. Participants were analyzed according to the group to which they were randomized. Not all participants contributed data for this outcome measure.

Change From Baseline To The Last Week Of Treatment In Ulcerative Colitis Symptoms, As Measured By Scores On The Rectal Bleeding NRS
Participants were required to record their rectal bleeding during the baseline and treatment periods in a daily diary. Participants graded rectal bleeding with a 4-point NRS as follows: 0 = No blood seen, 1 = Streaks of blood with stool less than half the time, 2 = Obvious blood with stool most of the time or more, 3 = Blood alone passes. For analysis, the baseline value was defined as the mean rectal bleeding score of the last 7 available days of the baseline period; the EOT value was defined as the mean rectal bleeding score of last 7 days of the treatment period, or last 7 days for which study drug was taken, where earlier.
