Inclusion Criteria: * Participants must have completed study I6T-MC-AMAG (NCT02891226) or study I6T-MC-AMAM (NCT03926130) * If female, participant must meet the contraception requirements Exclusion Criteria: * Participants must not have developed a new condition, including cancer in the previous study (I6T-MC-AMAG or I6T-MC-AMAM) that would pose an unacceptable risk in the trial. * Participants must not have any important infections including, but not limited to, hepatitis B, hepatitis C, HIV/AIDS, and active tuberculosis (TB) during either previous study. Note: Participants with a history of active TB with documentation of treatment by the Centers for Disease Control (CDC) and/or World Health Organization (WHO) criteria prior to the originator study are not excluded from the study. * Participants must not have a known hypersensitivity to any component of mirikizumab or have experienced acute systemic hypersensitivity event with previous study drug administration in the originating study that precludes mirikizumab therapy. * Participation must not be pregnant, lactating, or planning to become pregnant while enrolled in the study or 16 weeks after receiving the last dose of study drug.

Primary outcome measure(s)

  • Percentage of Participants Achieving Endoscopic Response at Week 52 (Participants Originating From AMAM Study) — Week 52
    Endoscopic Response defined as ≥50% reduction from AMAM study baseline in Simple Endoscopic Score for Crohn's Disease (SES-CD) total score. The SES-CD evaluates 4 endoscopic variables (presence/size of ulcers, extent of ulcerated surface, extent of affected surface, and presence/severity of stenosis) across 5 ileocolonic bowel segments (ileum, right colon, transverse colon, left colon, and rectum), with each of the 4 variables scored from 0 (best) to 3 (worst) per segment, resulting in 20 individual assessments. Total SES-CD score is the sum of all 20 individual assessment scores across all the bowel segments. Scores range from 0 to 56, with higher scores indicating more severe disease.
  • Percentage of Participants Achieving Clinical Remission at Week 52 (Participants Originating From AMAM Study) — Week 52
    Clinical remission was defined as a Crohn's Disease Activity Index (CDAI) total score \< (less than) 150. The CDAI measures the severity of active disease using 8 disease variables: stool frequency, severity of abdominal pain, degree of general well-being, presence or absence of extra-intestinal manifestations, presence or absence of fistula, use or non-use of antidiarrheal agents, presence or absence of an abdominal mass, hematocrit, and body weight. Each variable is assigned a specific weight/multiplier, and the weighted values are summed to produce a CDAI total score. CDAI total scores can range from 0 to 600, with higher scores indicating more severe disease.
