Purpose

The purpose of this study is to assess how well JNJ-78934804 works (efficacy) and how safe it is (safety) as compared to guselkumab at Week 48 in participants with moderately to severely active Crohn's disease (a long-term, progressive [worsens with time] and life-threatening disease of the intestine).

Inclusion Criteria

  • Have a diagnosis of Crohn's disease (CD) or fistulizing CD established greater than or equal to (>=) 12 weeks before screening including both endoscopic evidence and a histopathology report consistent with a diagnosis of CD - Have moderately to severely active CD based on crohn's disease activity index (CDAI) criteria defined as a baseline CDAI score >= 220 but less than or equal to (<=) 450 and either: a. Mean daily stool frequency (SF) count >= 4.0, based on the unweighted CDAI component of the number of liquid or very soft stools or b. Mean daily AP score >= 2.0, based on the unweighted CDAI component of abdominal pain (AP) - Have moderately to severely active ileal and/or colonic CD as assessed by central review of the screening video ileocolonoscopy based on simple endoscopic score for crohn's disease (SES-CD) criteria - Have had an inadequate initial response, loss of response, or intolerance to previously approved systemic therapies

Exclusion Criteria

  • Diagnosis of indeterminate colitis, microscopic colitis, ischemic colitis, ulcerative colitis (UC) or clinical findings highly suggestive of UC - Complications of CD such as symptomatic bowel strictures or stenoses, or any other manifestation that may require intestinal surgery while enrolled in the study - Presence of draining (that is, functioning) stoma or ostomy - Has a history of short bowel syndrome, is missing greater than (>) 2 of the 5 ileocolonic segments, or has any other medical condition that could preclude or confound the ability to use efficacy assessment tools (such as CDAI) to assess response to study intervention - Currently has or is suspected of having an abscess

Experimental
JNJ-78934804
Participants will receive JNJ-78934804 induction dose, at Weeks 0, 4, and 8 followed by JNJ-78934804 maintenance dose, once every 4 weeks (q4w) starting at Week 12. All participants who meet the rescue criteria will receive JNJ-78934804 induction dose at Weeks 16, 20, and 24 followed by JNJ-78934804 maintenance dose q4w starting at Week 28. Participants who complete double-blind treatment phase (Week 48) and who may benefit from continued study intervention in the opinion of the investigator will have the opportunity to enter the long-term extension (LTE) phase.
