Percentage of Participants Achieving Clinical Response (PRO2 Score = 8) at Week 8 of the Double-Blind Phase
Query!
Assessment method [1]
0
0
Clinical response was defined as patient-reported outcomes (PRO2) score = 8 at Week 8. PRO2 is the weighted average of the 2 variables of frequency of liquid or very soft stool and abdominal pain, based on 7-day participant diary data. The PRO2 score has a minimum score of 0 and has no upper bound, with a higher score indicating more frequent stools and more severe abdominal pain. Week 8 refers to the analysis window of Day 43 to Day 70 and prior to the first Open-Label dose date. Participants with a missing PRO2 value at the Week 8 analysis visit were imputed as not achieving the Clinical Response.

Percentage of Participants Achieving Endoscopic Response (= 50% Reduction From Baseline SES-CD) at Week 8 of the Double-Blind Phase
Query!
Assessment method [2]
0
0
Endoscopic response was defined as = 50% reduction from baseline in Simple Endoscopic Score for Crohn's Disease (SES-CD) at Week 8. The SES-CD evaluates 4 endoscopic variables: ulcer size, ulcerated surface, affected surface, and presence of narrowings. The total SES-CD is calculated as the sum of the 4 variables for the 5 bowel segments: rectum, left colon, transverse colon, right colon, and ileum. Scores range from 0 to 60, with higher scores indicating more severe disease. Week 8 refers to the analysis window of Day 43 to Day 70 and prior to the first Open-Label dose date. Participants with missing SES-CD value at Week 8 analysis visit were imputed as not achieving Endoscopic Response.

Percentage of Participants Achieving CDAI Remission (CDAI = 150) at Week 8 of the Double-Blind Phase
Query!
Assessment method [1]
0
0
Clinical remission was defined as Crohn's Disease Activity Index (CDAI) = 150 at Week 8. CDAI is used as a measure of clinical response and remission. It includes 8 variables of patient-reported symptoms and objective variables: stool count, abdominal pain, general well-being, complications, use of anti-diarrheal medications, presence of abdominal mass, hematocrit values, and weight. It has a minimum range of 0 and no upper bound, with higher scores indicating greater disease activity. Week 8 refers to the analysis window of Day 43 to Day 70 and prior to the first Open-Label dose date. Participants with missing CDAI score at Week 8 analysis visit were imputed as not achieving CDAI Remission.

Percentage of Participants Achieving Mucosal Healing (SES-CD Size-of-Ulcer Subscore = 0) at Week 8 of the Double-Blind Phase

Assessment method [2]

The SES-CD evaluates 4 endoscopic variables: ulcer size, ulcerated surface, affected surface, and presence of narrowings. The SES-CD size-of-ulcer subscore ranges from 0 (none) to 3 (very large). Mucosal healing at Week 8 was defined as the size-of-ulcer subscore for segments with non-zero baseline value changes to zero at Week 8 AND the size-of-ulcer subscore for segments with zero value at baseline remain zero at Week 8. Week 8 refers to the analysis window of Day 43 to Day 70 and prior to the first Open-Label dose date. Participants with missing SES-CD size-of-ulcer subscore at Week 8 analysis visit were imputed as not achieving Mucosal Healing.

Summary
Brief summary
This study will primarily evaluate the safety and efficacy of andecaliximab in adults with active Crohn's disease. The study will consist of a Double-Blind Phase of 8 weeks followed by an Open-Label Extension. Participants who complete the Double-Blind Phase will be eligible to enroll in the optional Open-Label Extension for an additional 44 weeks. Participants who complete Week 52 assessments will be eligible to enter the Extended Treatment Phase to continue treatment with andecaliximab for an additional 156 weeks.
