The primary purpose of this study is to evaluate the efficacy and safety of a single intravenous (IV) re-induction dose of approximately 6 milligram per kilogram (mg/kg) ustekinumab in participants with secondary loss of response (LoR) to subcutaneous (SC) every 8 Weeks (q8w) 90 mg ustekinumab maintenance therapy.
This study compares the efficacy and safety of a single weight-tiered based IV re-induction dose of approximately 6 mg/kg ustekinumab versus continuing with regular SC q8w 90 mg ustekinumab administration. It consists of screening (5 weeks); treatment period (Week 0 to 24); and safety follow up visit (20 weeks after last dose). The primary hypothesis is that a single IV re-induction dose of ustekinumab is superior to continuing with regular SC q8w maintenance treatment as measured by clinical response after 16 weeks of treatment. Study assessments will include Crohn's disease activity index (CDAI), video ileocolonoscopy, patient-reported outcomes (PROs), laboratory evaluations, biomarkers, review of concomitant medications and adverse events (AEs), and evaluation of serum concentrations of study agent as well as development of antibodies to study agent. All participants will be randomly assigned to receive either ustekinumab IV re-induction or regular SC q8w 90 mg ustekinumab injection at baseline in a double dummy design. No participants will be treated with placebo only.

Percentage of Participants With Clinical Response at Week 16
Clinical response was defined as greater than or equal to (\>=) 100-point reduction from baseline in Crohn's disease activity index (CDAI) score or a CDAI score \< 150 points. CDAI is validated multi-item measure of severity of illness derived as weighted sum of 8 different Crohn's disease (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). The last 4 variables were scored over 7 days by participant on diary card. In general, CDAI score ranges from 0 to approximately 600; higher score=higher disease activities. Participants who had prohibited CD-related surgery, prohibited concomitant medication changes or discontinued study agent due to lack of efficacy or adverse event indicated to be of worsening CD prior to designated analysis timepoint were considered not to be in clinical response, regardless of their CDAI score.
Time frame: Week 16

Percentage of Participants With Normalization of C-reactive Protein (CRP) and/or Normalization of Fecal Calprotectin (fCal) Concentration at Week 16
Percentage of participants with normalization at Week 16, among participants with elevated CRP and/or fCal at baseline were reported. Participants were considered to be normalized if at least one biomarker (fCal or CRP) was normalized. Normalized CRP=CRP value less than or equal to (\<=) 3 milligrams per liter(mg/L). Normalized fCal concentrations was defined as \<=250 micrograms per gram(mcg/g). When either CRP or FCal value was abnormal at baseline and value of same parameter normalizes at designated analysis timepoint, participants were considered to be normalized at designated analysis timepoint.

Percentage of Participants With Treatment-emergent Adverse Events (TEAEs)
An adverse event was any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non-investigational) product. An adverse event does not necessarily have a causal relationship with the treatment. TEAEs were adverse events with onset during the intervention phase or that were a consequence of a pre-existing condition that had worsened since baseline. Any AE occurring at or after the initial administration of study agent through the end of the trial was considered to be treatment emergent. In this outcome measure, TEAEs including all AEs irrespective of being serious or non-serious AE are reported.
Time frame: From baseline (Week 0) up to Week 36
Percentage of Participants With Treatment-emergent Serious Adverse Events (TESAEs)

TESAEs were adverse events with onset during the intervention phase or that are a consequence of a pre-existing condition that had worsened since baseline. Any AE occurring at or after the initial administration of study agent through the end of the trial was considered to be treatment emergent.
Time frame: From baseline (Week 0) up to Week 36
