3. Male and/or female subjects between the ages of ≥18 and ≤65 years at the time of informed consent.
4. A diagnosis of UC for ≥3 months. A biopsy report must be available to confirm the histological diagnosis in the subject’s source documentation. In addition, a report documenting disease duration and extent of disease (e.g., proctosigmoiditis, left-sided colitis and pancolitis) based upon prior colonoscopy must also be available in source documentation. NOTE: A colonoscopy with biopsy will need to be performed, if this documentation is not available.

9. Male and female subjects of childbearing potential must agree to use a highly effective method of contraception (defined at the time of signing the informed consent) throughout the study and through the conclusion of subject participation. A subject is of childbearing potential if, in the opinion of the investigator, he/she is biologically capable of having children and is sexually active.
