Eligibility Criteria:
Inclusion Criteria:~Note: Adolescent participants who are 16 or 17 years old will be eligible to participate if approved by the country or regulatory/health authority. If approval has not been granted, only participants ≥18 years old will be enrolled. Adolescents must weigh ≥ 40 kilograms and meet the definition of Tanner Stage 5 at Screening Visit.~* Diagnosis of ulcerative colitis for 90 days or greater prior to Baseline, confirmed by colonoscopy during the Screening Period, with exclusion of current infection, colonic dysplasia and/or malignancy.

Study Arms:
- SS1: Placebo (Type: PLACEBO_COMPARATOR): During the 8-week induction phase in Substudy 1, participants received placebo for upadacitinib film-coated tablets once daily by mouth (QD) for 8 weeks.
- SS1: Upadacitinib 7.5 mg (Type: EXPERIMENTAL): During the 8-week induction phase in Substudy 1, participants received 7.5 mg upadacitinib film-coated tablets once daily by mouth (QD) for 8 weeks.
- SS1: Upadacitinib 15 mg (Type: EXPERIMENTAL): During the 8-week induction phase in Substudy 1, participants received 15 mg upadacitinib film-coated tablets once daily by mouth (QD) for 8 weeks.
- SS1: Upadacitinib 30 mg (Type: EXPERIMENTAL): During the 8-week induction phase in Substudy 1, participants received 30 mg upadacitinib film-coated tablets once daily by mouth (QD) for 8 weeks. Additional participants were enrolled during the Substudy 1 analysis period and received 30 mg upadacitinib film-coated tablets once daily by mouth (QD) for 4 weeks.
- SS1: Upadacitinib 45 mg (Type: EXPERIMENTAL): During the 8-week induction phase in Substudy 1, participants received 45 mg upadacitinib film-coated tablets once daily by mouth (QD) for 8 weeks. Additional participants were enrolled during the Substudy 1 analysis period and received 45 mg upadacitinib film-coated tablets once daily by mouth (QD) for 4 weeks.
- SS2: Placebo/Upadacitinib 45 mg (Type: EXPERIMENTAL): During the Substudy 2 Part 1 induction period, participants received placebo for upadacitinib film-coated tablets once daily by mouth (QD) for 8 weeks. Participants who did not achieve clinical response at Week 8 of Part 1 were enrolled in an open-label extended treatment period and received 45 mg upadacitinib film-coated tablets once daily by mouth (QD) for an additional 8 weeks.
- SS2: Upadacitinib 45 mg/Upadacitinib 45 mg (Type: EXPERIMENTAL): During the Substudy 2 Part 1 induction period, participants received 45 mg upadacitinib film-coated tablets once daily by mouth (QD) for 8 weeks. Participants who did not achieve clinical response at Week 8 of Part 1 were enrolled in an open-label expended treatment period and received 45 mg upadacitinib film-coated tablets once daily by mouth (QD) for an additional 8 weeks.
- SS3: M14-675 clinical responders (Type: EXPERIMENTAL): Participants in Study M14-675 (NCT03653026) who achieved clinical response defined by Adapted Mayo Score at Week 8 or Week 16 in that study and did not meet any study discontinuation criteria were eligible to enroll into Substudy 3. Participants were re-randomized and treated with a blinded treatment assignment (15 mg upadacitinib film-coated tablets once daily by mouth \[QD\], or 30 mg upadacitinib film-coated tablets QD, or placebo for upadacitinib film-coated tablets QD) for up to 52 weeks.
