- Number of Participants with Symptomatic Remission at M-44 Visit [ Time Frame: Week 52 ]Symptomatic remission is defined as Mayo stool frequency subscore of 0 or 1 and a rectal bleeding subscore of 0, where the stool frequency subscore has not increased from induction baseline.

- A participant who has had extensive colitis for >= 8 years, or disease limited to the left side of the colon for >= 10 years, must: a) have had a full colonoscopy to assess for the presence of dysplasia within 1 year before the first administration of study intervention or b) have a full colonoscopy with surveillance for dysplasia as the baseline endoscopy during the screening period.

- Presence or history of colonic or small bowel obstruction within 6 months prior to screening, confirmed by objective radiographic or endoscopic evidence of a stricture with resulting obstruction (dilation of the colon or small bowel proximal to the stricture on barium radiograph or an inability to traverse the stricture at endoscopy)
- Have a history of latent or active granulomatous infection, including tuberculosis (TB), histoplasmosis, or coccidioidomycosis, or have had a nontuberculous mycobacterial infection prior to screening
- Presence or history of any malignancy including presence or history of lymphoproliferative disease including lymphoma, or signs and symptoms suggestive of possible lymphoproliferative disease, such as lymphadenopathy of unusual size or location (example, nodes in the posterior triangle of the neck, infraclavicular, epitrochlear, or periaortic areas) and monoclonal gammopathy of undetermined significance, or clinically significant hepatomegaly or splenomegaly
- Has known allergies, hypersensitivity, or intolerance to ustekinumab or its excipients
