A male participant who is nonsterilized and sexually active with a female partner of childbearing potential agrees to use a barrier method of contraception (e.g., condom with spermicide) from signing of informed consent throughout the duration of the study and for 18 weeks after last dose. The female partner of a male participant should also be advised to use a highly effective method of contraception.~7. A female participant of childbearing potential who is sexually active with a nonsterilized male partner agrees to use a highly effective method of contraception from signing of informed consent throughout the duration of the study and for 18 weeks after last dose.~Exclusion Criteria:~Gastrointestinal Exclusion Criteria~1.

A diagnostic TB test performed within 30 days of Screening or during the Screening Period that is positive, as defined by:~   1. A positive QuantiFERON test or 2 successive indeterminate QuantiFERON tests. OR~  2. A tuberculin skin test reaction ≥10 mm (≥5 mm in participants receiving the equivalent of \>15 mg/day prednisone).~      OR~2. Chest X-ray within 3 months prior to Day 1 that is suspicious for pulmonary TB, and a positive or 2 successive indeterminate QuantiFERON test within 30 days prior to Screening or during the Screening Period.~   3. Has chronic hepatitis B virus (HBV) infection\* or chronic hepatitis C virus (HCV) infection\*\* or a known history of human immunodeficiency virus (HIV) infection (or is found to be seropositive at Screening) or participant is immunodeficient (e.g., due to organ transplantation, history of common variable immunodeficiency, etc).~   \* Participants who are positive for hepatitis B virus surface antigen (HBsAg) will be excluded. For participants who are negative for HBsAg but are positive for either surface antibodies and/or core antibodies, HBV Deoxyribonucleic acid (DNA) polymerase chain reaction will be performed and if any test result meets or exceeds detection sensitivity, the participant will be excluded.~  * If participant is HCV antibody positive, then a viral load test will be performed. If the viral load test is positive then the participant will be excluded.~     4. Has evidence of active infection with Clostridium (C) difficile during Screening (to be confirmed by laboratory test)~   General Exclusion Criteria~  1.

Has a history of hypersensitivity or allergies to vedolizumab or its components.~  3. Has allergies to and/or contraindications for ciprofloxacin, a history of tendon disorders related to quinolone administration and/or glucose-6-phosphate dehydrogenase (G6PD) deficiency. Further conditions requiring precautions for use of ciprofloxacin have to be considered based on local prescribing information.~  4. Is taking, has taken, or is required to take any excluded medications.~  5. Has received any investigational or approved biologic or biosimilar agent within 60 days prior to Randomization.~  6. Has received an investigational nonbiologic therapy within 30 days prior to Randomization.~  7. Has received an approved nonbiologic therapy (including 5-aminosalicylate \[5-ASA\], corticosteroid, azathioprine, 6-mercaptopurine \[6-MP\], etc.) in an investigational protocol within 30 days prior to Randomization.~  8.
