Group Intervention Description Part II : JNJ-64304500 Middle Dose JNJ-64304500 JNJ-64304500 150 mg SC at Week 0 and 75 mg SC at Weeks 2, 4, 8, 12, 16, and 20. Participants who complete Part II 24 weeks assessment and may benefit from continued treatment in the opinion of the investigator are eligible to enter the Part II LTE in which they will continue to receive JNJ-64304500 middle dose up to 52 weeks (for a total of up to 72 weeks of JNJ-64304500 in Part II). The study has been unblinded due to lack of sufficient efficacy of JNJ-64304500. Participants receiving JNJ-64304500 during the LTE will stop receiving study drug and will have a final safety follow-up visit 16 weeks after the last dose of study drug. Part II : Placebo Placebo Placebo SC at Weeks 0, 2, 4, and 8.

Participants who complete Part II 24 weeks assessment and may benefit from continued treatment in the opinion of the investigator are eligible to enter the Part II LTE in which they will continue to receive placebo up to 52 weeks (for a total of up to 72 weeks of placebo in Part II). The study has been unblinded due to lack of sufficient efficacy of JNJ- 64304500. Participants receiving placebo during the LTE will stop receiving placebo. Part II : Ustekinumab Ustekinumab Participants will receive tiered doses of Ustekinumab 260 mg (weight \<=55 kg), Ustekinumab 390 mg (weight \>55 kg and \<=85 kg), Ustekinumab 520 mg (weight \>85 kg) intravenously at Week 0 followed by 90 mg subcutaneously at Weeks 8 and 16. Participants who complete Part II 24 weeks assessment and may benefit from continued treatment in the opinion of the investigator are eligible to enter the Part II LTE in which they will continue to receive Ustekinumab up to 52 weeks (for a total of up to 72 weeks of Ustekinumab in Part II). The study has been unblinded due to lack of sufficient efficacy of JNJ-64304500. Participants receiving Ustekinumab during the LTE will stop receiving study drug and will have a final safety follow-up visit after the last dose of study drug. However, participants receiving Ustekinumab in countries where Ustekinumab is not commercially available or approved for adult Crohn's disease were continued to receive Ustekinumab in the LTE.
- Primary Outcome Measures
Name Time Method Part I: Change From Baseline in the Crohn's Disease Activity Index (CDAI) Score at Week 8 Baseline to Week 8 The CDAI is a validated multi-item measure of severity of illness derived as a weighted sum of 8 different Crohn's disease-related variables. The CDAI score was assessed by collecting information on 8 different Crohn's disease-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. The last 4 variables were scored over 7 days by the participant on a diary card. In general, CDAI score ranges from 0 to approximately 600; higher score indicates higher disease activities.
Part II: Change From Baseline in the CDAI Score at Week 12 Baseline to Week 12 The CDAI is a validated multi-item measure of severity of illness derived as a weighted sum of 8 different Crohn's disease-related variables. The CDAI was assessed by collecting information on 8 different Crohn's disease-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. The last 4 variables are scored over 7 days by the participant on a diary card. In general, CDAI score ranges from 0 to approximately 600; higher score indicates higher disease activities.
- Secondary Outcome Measures
Name Time Method Part II: Percentage of Participants in Clinical Remission at Week 12 as Measured by PRO-2 (PRO-2 <75) Week 12 Clinical Remission was defined as a PRO-2 score of \<75 point.
Part II: Percentage of Participants in Clinical Remission at Week 12 as Measured by CDAI (CDAI Less Than [<] 150) Week 12 Clinical Remission was defined as a CDAI score of \<150 point. The CDAI score is used to quantify the symptoms of participants with Crohn's Disease. The CDAI is a validated multi-item measure of severity of illness derived as a weighted sum of 8 different Crohn's disease-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. A decrease in CDAI over time indicates improvement in disease activity. In general, CDAI score ranges from 0 to approximately 600; higher score indicates higher disease activities.
Part II: Percentage of Participants in Clinical Response at Week 12 as Measured by CDAI (Greater Than or Equal to [>=] 100-point Reduction From Baseline in CDAI or CDAI <150) Week 12 Clinical response was defined as a \>=100-point reduction from the baseline CDAI score, or a CDAI score \<150. The CDAI score is used to quantify the symptoms of participants with Crohn's Disease. The CDAI is a validated multi-item measure of severity of illness derived as a weighted sum of 8 different Crohn's disease-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. The CDAI score is used to quantify the symptoms of participants with Crohn's Disease. A decrease in CDAI over time indicates improvement in disease activity. In general, CDAI score ranges from 0 to approximately 600; higher score indicates higher disease activities.
Part II: Change From Baseline in Patient-Reported Outcome (PRO)-2 at Week 12 Baseline, Week 12 The PRO-2 score is defined as the sum of the abdominal pain and stool frequency components of the CDAI. PRO-2 scores ranges from 0 to approximately 300, higher score indicates higher disease activity.
Part II: Percentage of Participants in Clinical Response at Week 12 as Measured by PRO-2 (>=50-point Reduction From Baseline in PRO-2 Score or PRO-2 Score <75) Week 12 Clinical response was defined as \>=50-point reduction from baseline in PRO-2 or Score or PRO-2 Score \<75.
Part II: Change From Baseline in Simple Endoscopic Score for Crohn's Disease (SES-CD) at Week 12 Baseline, Week 12 SES-CD is a validated instrument reflecting an endoscopist global appraisal of mucosal lesions in Crohn's disease. SES-CD grades lesions by location (5 bowel segments: ileum, right colon, transverse colon, left colon, and rectum) using 4 endoscopic variables: ulcer size, extent of ulcerated surface, extent of affected surface, and presence/type of narrowing. The total SES-CD was 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.
