Arm Intervention/treatment
Experimental: Guselkumab
Participants will receive guselkumab by intravenous (IV) infusion, followed by guselkumab by subcutaneous (SC) injection. Participants who are eligible and willing to continue guselkumab may enter the Long-term extension (LTE) phase and continue to receive guselkumab.
Drug: Guselkumab
Guselkumab will be administered intravenously for the first 3 doses and then subcutaneously for the subsequent doses.
Other Name: CNTO1959

Primary Outcome Measures :
  1. Number of Participants with Adverse Events as a Measure of Safety and Tolerability [ Time Frame: Up to Week 48 ]
    An Adverse Event (AE) is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the intervention under study.

Secondary Outcome Measures :
  1. Change from Baseline in the Crohn's Disease Activity Index (CDAI) Score [ Time Frame: Baseline to Week 48 ]
    The CDAI score will be assessed by collecting information on 8 different Crohn's disease-related variables, with score ranges from 0 to approximately 600. A decrease over time indicates improvement in disease activity. .

  2. Change from Baseline in Patient-Reported Outcome (PRO)-2 Score [ Time Frame: Baseline to Week 48 ]
    PRO-2 is based on unweighted CDAI components of the total number of liquid or very soft stools and the abdominal pain (AP) score. The PRO-2 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.

  3. Change from Baseline in Simplified Endoscopic Score for Crohn's disease (SES-CD) Score [ Time Frame: Baseline and Week 48 ]
    The SES-CD score will be used to evaluate endoscopic improvement based on presence/size of ulcers, mucosal surface covered by ulcers, mucosal surface affected by any other lesions, and presence/type of narrowing/structures) across 5 ileocolonic segments.

  4. Serum Concentation of Guselkumab [ Time Frame: Up to Week 48 ]
    Serum concentration of Guselkumab will be reported.

  5. Number of Participants with Anti-Guselkumab Antibodies [ Time Frame: Up to Week 48 ]
    Number of participants with anti-Guselkumab antibodies will be reported.

  6. Change from Baseline in C-reactive protein (CRP) [ Time Frame: Baseline and Week 4, 8, 12, 16, 20, 24, 32, 40 and 48 ]
    Change from baseline in C-reactive protein (CRP) will be reported.

  7. Change from Baseline in Fecal Calprotectin (FC) Levels [ Time Frame: Baseline and Week 4, 8, 12, 24 and 48 ]
    Change from baseline in Fecal Calprotectin (FC) Levels will be reported.
