Outcomes
Primary Outcome Measures
Number Of Participants With A Mayo Score Of 2 Or Less (With No Sub-score >1) At EOT
The Mayo score is an assessment of ulcerative colitis activity. The Mayo total score ranges from 0 to 12 points with higher scores indicating more severe disease. The total score is made up of 4 sub-scores, each of which is assessed using a 0 to 3 scale. 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); Physician's Global Assessment of Illness Severity (PGAS): 0 = none, 1 = mild, 2 = moderate, and 3 = severe.

Secondary Outcome Measures
Distribution On The PGAS At EOT
The PGAS required the physician to assess participants' disease severity on a 4-point scale (0=normal [no disease], 1 = mild disease, 2 = moderate disease, 3 = severe disease).
Distribution On The PGAS At EOT - PP Analysis
The PGAS required the physician to assess participants' disease severity on a 4-point scale (0 = normal [no disease], 1 = mild disease, 2 = moderate disease, 3 = severe disease).
Change From Baseline To EOT In The PGAS Score
The PGAS required the physician to assess participants' disease severity on a 4-point scale (0=normal [no disease], 1 = mild disease, 2 = moderate disease, 3 = severe disease). A negative change from Baseline indicates that symptoms decreased.
Change From Baseline To EOT In The PGAS Score - PP Analysis
The PGAS required the physician to assess participants' disease severity on a 4-point scale (0=normal [no disease], 1 = mild disease, 2 = moderate disease, 3 = severe disease). A negative change from Baseline indicates that symptoms decreased.
Change From Baseline To EOT In The Inflammatory Bowel Disease Questionnaire (IBDQ) Total Score
The IBDQ is a validated and reliable tool to measure health-related quality of life in adult participants with inflammatory bowel disease (IBD). Each of the 32 questions falls into 1 of 4 domains (bowel symptoms, systemic symptoms, emotional status and social function). The 32 questions each have 7 possible responses. Each response is assigned a score ranging from 1 to 7, indicating the severity (1 being least favorable and 7 being the most favorable). Individual question scores were summed to give the IBDQ total score (range: 32 to 224 points). A positive change from Baseline indicates that symptoms improved.

Number Of Participants Who Reported An Improvement In The Subject Global Impression Of Change (SGIC) Questionnaire At EOT
Participants were asked to answer the following question by using a 7-point scale (1 = very much better to 7 = very much worse): "Please assess the change in your ulcerative colitis symptoms since immediately before receiving the first dose of study treatment." Improvement was considered as very much better, much better, or minimally better.

Change From Baseline To The Last Week Of Treatment In Ulcerative Colitis Symptoms, As Measured By Scores On The Stool Frequency Numerical Rating Scale (NRS)
Participants were required to record their stool frequency during the baseline and treatment periods in a daily diary. Participants graded stool frequency with a 4-point NRS as follows: 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. For analysis, the baseline value was defined as the mean stool frequency score of the last 7 available days of the baseline period; the EOT value was defined as the mean stool frequency score of last 7 days of the treatment period, or last 7 days for which study drug was taken, where earlier. A negative change from Baseline indicates that symptoms improved.

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.
