Study Endpoints

Primary Endpoints

Number of Participants with Deep Remission at Week 52
At Week 52

Deep remission is a composite endpoint defined as achieving both clinical remission and endoscopic remission at the participant level. Clinical remission is defined as Crohn's Disease Activity Index (CDAI) score less than (\<) 150-point. CDAI will be assessed by collecting information on 8 different CD-related variables: extra-intestinal manifestations, abdominal mass, weight, hematocrit, total number of liquid stools, abdominal pain/cramping, use of antidiarrheal drug(s), and/or opiates, and general well-being. In general, CDAI score ranges from 0 to approximately 600. Higher score indicates higher disease activity. Endoscopic remission is defined as Simple Endoscopic Score for Crohn's Disease (SES-CD) less than or equal to (\<=) 4 with at least a 2-point reduction from baseline and no sub score greater than (\>) 1 in any individual component and score can range from 0 to 56. Higher scores indicating severe disease.

Percentage of Participants Achieving a Magnetic Resonance Index of Activity (MaRIA) Less Than (<)11 in All Intestinal Segments at Week 48
At Week 48

Percentage of participants achieving a MaRIA \<11 in all intestinal segments at Week 48 will be reported. The MaRIA scoring system is used to grade severity in Crohn's Disease (CD) by assessing ileocolonic CD activity on contrast-enhanced magnetic resonance imaging (MRI) enterography. Active disease is defined as a MaRIA score greater than or equal to (\>=)7 whereas severe disease is defined as a MaRIA score \>=11.

Percentage of Participants with Clinical Remission at Week 52
Week 52

Percentage of participants with clinical remission at Week 52 will be assessed. Clinical remission is defined as pediatric Crohn's Disease activity index (PCDAI) less than or equal to (\<=) 10.

Percentage of Participants Who Achieve Endoscopic Response at Week 52
Week 52

Percentage of participants who achieve endoscopic response at Week 52 will be assessed. Endoscopic response is defined as greater than or equal to (\>=) 50 percent (%) reduction (global) and greater than (\>) 50% reduction (U.S specific) from simplified endoscopic score-Crohn's Disease (SES-CD) score at baseline.

Percentage of Participants Who Achieved Clinical Remission at Week 12
At Week 12

Clinical remission was defined as a Crohn's Disease Activity Index (CDAI) score \<150. The multi-item CDAI score assessed severity of illness by collecting information on 8 different Crohn's disease-related variables (extraintestinal manifestations, abdominal mass, weight, hematocrit, use of antidiarrheal drug(s) and/or opiates, total number of liquid or very soft stools, abdominal pain/cramps, and general well-being). The last 3 variables were scored over 7 days by the participant on a diary card. The total CDAI score ranged from 0 (improvement in disease activity) to 600 (more disease activity) and a decrease in total CDAI score over time indicates improvement in disease activity.

Percentage of Participants Who Achieved Endoscopic Response at Week 12
At Week 12

Percentage of participants who achieved endoscopic response at Week 12 were reported. Endoscopic response was defined as greater than or equal to (\>=) 50 percent (%) improvement from baseline in the Simple Endoscopic Score for Crohn's Disease (SES-CD) score. SES-CD evaluated 4 endoscopic components (presence and size of ulcer, extent of ulcerated surface, extent of affected surface, and presence and type of narrowing) across 5 ileocolonic segments (ileum, right colon, transverse colon, left colon, and rectum), each scored from 0 (best) to 3 (worst) for each segment except narrowing component for which the maximum total score (that is, stricturing) was 11 points. The total SES-CD score was the sum of all the component scores across all the segments and it ranged from 0 (best) to 56 (worst), where higher scores indicated more severe disease.

Percentage of Participants with Clinical Remission at Week 48
Week 48

Percentage of participants with clinical remission at Week 48 will be reported. Clinical remission is based on the Crohn's Disease Activity Index (CDAI).

Percentage of Participants with Endoscopic Response at Week 48
Week 48

Percentage of participants with endoscopic response at Week 48 will be reported. Endoscopic response is based on change from baseline in the simple endoscopic score for Crohn's disease (SES-CD), as assessed by central endoscopy reading.

Main Study: Change From Baseline in Modified Rodnan Skin Score (mRSS) at Week 24
Baseline and Week 24

Change from baseline in mRSS at Week 24 was reported. The mRSS is an accepted clinical measure of skin thickness. The investigator assessed the thickening of the skin using the mRSS through simple palpation on 17 different skin sites in the fingers, hands, forearms, arms, feet, legs, and thighs (bilaterally) and face, chest, and abdomen (singly). Each skin site was rated on a 0 to 3 scale; where 0 = normal skin, 1 = mild thickness, 2 = moderate thickness, and 3 = severe thickness and unable to pinch. Individual skin scores in the 17 body areas were summed and defined as the total mRSS which ranged from 0 (no thickening) to 51 (severe thickening), where higher score indicated more severity of skin thickening/worst outcome.

Percentage of Participants Achieving Hidradenitis Suppurativa Clinical Response (HiSCR) at Week 16
Week 16

HiSCR is defined as at least 50 percent (%) reduction in total abscess and inflammatory nodule (AN) count with no increase in abscess count and no increase in draining fistula count relative to baseline.

GALAXI 1: Change From Baseline in the Crohn's Disease Activity Index (CDAI) Score at Week 12

The last 3 variables were scored over 7 eligible days by the participant on a diary card. The total CDAI score ranged from 0 to 600 in general: higher score indicated higher disease activities. A decrease in total CDAI score over time indicates improvement in disease activity. Baseline was defined as the last observation prior to or at the date of the first study intervention.

Global: GALAXI 2: Percentage of Participants With Both Clinical Response at Week 12 and Clinical Remission at Week 48
Weeks 48
