Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: Participants will be randomized to one of two groups: Evening Time or Morning Time. Participants are used as their own control. The evening time group will take their medication in the evening and the morning time group will take the medication in the morning.
Primary purpose: TREATMENT

Brief summary: This study aims to determine if there is any difference in the efficacy of Inflammatory Bowel Disease (IBD) medication and disease outcomes when taken in the morning or in the evening. The IBD medications being observed are azathioprine and 6-mercaptopurine. The study team believes that there may be a benefit to taking the medication at a certain time of day. To test this theory the study asks participants who are already taking either azathioprine or 6-mercaptopurine for IBD to take the medication consistently at either the morning or in the evening based on when they currently take their medication. Participation is up to 10 weeks +/- 3 days. There will be 2 study visits where the participant will be asked to fill in questionnaires related to their IBD symptoms, their sleep habits, sleep quality, and general health information followed by a blood draw.

Detailed description: The objective of this study is to determine whether the timing of drug administration to treat inflammatory bowel disease (IBD) has an effect on patient outcomes. Primary objective: Determine whether there is a difference in outcomes seen when patients are assigned to take their prescribed immunomodulator (IM) - either Azathioprine or 6-Mercaptopurine - at either a morning delivery time or evening delivery time.

The Investigator hypothesize that administration time of immunomodulators (IMs) during the day can affect the clinical outcomes in IBD patients.

Specific Aims Include:

* Determine whether morning vs. evening dosing of patients' prescribed IMs (either Azathioprine or 6-Mercaptopurine) could affect the subclinical markers of inflammation related to disease.
* Determine whether morning vs. evening dosing of patients' prescribed IMs (either Azathioprine or 6-Mercaptopurine) could affect endoscopic outcomes.
* Determine whether morning vs. evening dosing of IMs affect their biochemical side effects, as is routinely monitored as part of the patients' clinical care.
* Determine if outcomes correlate with patients' chronotype, as determined by standard questionnaires (the Munich Chronotype Questionnaire).

Description of Procedures: After signing the informed consent form, subjects will be asked to answer the Inflammatory Bowel Disease Questionnaire (IBDQ), the Munich Chronotype Questionnaire (MCTQ), the Harvey Bradshaw questionnaire, and a demographics survey. All six of these questionnaires are included with this IRB. Next, patients will be assigned a time (morning or evening) to self administer their prescribed medication for 10 weeks. Patients who currently take their medication in the morning will be asked to switch to an evening delivery and patients who currently take their medication at night will be asked to switch to a morning delivery. The group assigned to morning delivery time will be told to take their medication between 6am and 11am. The group assigned to evening delivery time will be told to take their medication between 6pm and 11pm. Lastly, patients will be asked to give a blood sample to test for complete blood count (CBC), comprehensive metabolic panel (CMP), C-reactive protein (CRP), methylmercaptopurine (6-MMP), and thioguanine nucleotides (6-TG). Plasma and serum isolated from the blood sample will be temporarily stored to measure inflammatory cytokines after every 20 subjects complete the study.

Within a 6-10 week window, as part of their clinical care, subjects will come in to assess their clinical status while undergoing biochemical monitoring every 2-4 weeks. Data from their endoscopic examination, if done, will also be collected.

After 10 weeks, the subjects will be asked to complete the IBDQ and Harvey Bradshaw questionnaire. In addition, a blood sample will be obtained to measure the same metabolite levels and other biochemical indications of disease as stated above. Again, plasma and serum will be isolated from the blood sample and stored.
