- Females of Reproductive Potential:
- If a female subject becomes pregnant while on this study, the study drug will be discontinued immediately and the subject followed until the outcome of the pregnancy is known. If a pregnancy occurs, it will be reported in the same manner as an unexpected AE using the guidelines provided in Section 6.4.1.9.
- Premature Subject Discontinuation:
- A subject may be discontinued from the study for the following medical or administrative reasons:
- Occurrence of an AE, which in the judgment of the investigator suggests an unacceptable risk to the subject (The investigator will follow the subject until satisfactory resolution of the AE or the AE is determined to be stable);
- Development on-study of any condition which, in the opinion of the investigator or the study sponsor, places the subject at an unacceptable medical risk if he/she continues;
- Pregnancy;
- Subject request;
- Institution of additional medical (rescue) therapy for UC. The investigator may discontinue individual subjects from the study at any time. Subjects will be encouraged to complete the study; however they may voluntarily withdraw at any time. The investigator must provide written documentation of the reason for discontinuation on the CRF. Regardless of the reason for withdrawal, all subjects will be asked to undergo an end of therapy evaluation. Every attempt will be made to obtain all the end of study assessments, including all of the subscales of the MMDAI (i.e., bowel frequency, bleeding, physician's assessment, and endoscopy/sigmoidoscopy score).
- Subjects who withdraw or are withdrawn will not be replaced under this protocol.
