Clinical Trial Summary

Nutritional Saffron supplement has been widely used as food supplement and has known anti-depressant and anti-inflammatory activities. It is generally consumed as stigmas in drinks or dishes. The investigators use saffron extract in patients with colitis for 8 weeks.

Description:

The patients invited to participate in a research study on Inflammatory Bowel Diseases (IBD) and saffron as a nutritional anti-inflammatory supplement. Inflammatory Bowel Disease (IBD) is composed of Crohn's Disease (CD) and Ulcerative Colitis (UC). Continuous altered immune responses and inflammation associate with this disease. More than two-thirds of patients reported that IBD-associated symptoms negatively affected their quality of life and their performance at work. - Patients with IBD are generally put on immunosuppressants (that block or slow participants' immune system to lower the level of inflammation). Long-term use of these immunosuppressants have some serious side effects. - The goal of this protocol is to lower the need for these immunosuppressants by giving saffron as capsules in two different doses. The investigators will assess whether the addition of saffron will improve the overall patient's status and decrease the need for immunosuppressants. If participants have been prescribed immunosuppressants by the participant's doctor, saffron will be added to the participants' treatment. - The investigators request that the subject answer as many questions as they can during this visit. If they are unable to complete the questionnaires during this visit, the investigators ask them to please return them within 7 days. If the investigators do not receive the questionnaires, the investigators will make one phone call to remind the subjects to send the questionnaires back. - The subject medical record and colonoscopy report will be used to determine IBD or health status, the blood sample will be used to assess immune markers (inflammatory and antiinflammatory), stool sample will be used to assess some inflammation markers and saffron effect on the intestinal bacterial composition, a saliva sample will be used to assess whether saffron selectively affects the intestinal bacteria but not the saliva bacteria and the urine sample will be used to assess saffron release in body fluids. - Participants are being asked to participate in this research project because participants are having a normal colonoscopy for screening, or IBD. - If a biopsy is taken at colonoscopy. a pathologist will use a portion to make a diagnosis. The investigators are requesting permission to use a portion of the excess tissue that the pathologist does not need, for this research project. - Samples will be collected at baseline (day 0) and 8 weeks later after saffron capsules utilization. - This is a double-blind clinical trial, you will not know whether participants are given a placebo (capsule without saffron) or saffron dose 1 or 2. This is important for participants and for the study process, to avoid any psychological effect on the expected saffron effect. - However, by the end of the 8 weeks and after collecting and analyzing the data from all participants, the investigators will inform the subject of what the subjects were given and potential next steps.

• Gender: All
• Age group: 18 Years to 80 Years

Eligibility

Inclusion Criteria:

1. Male or female patients aged >18 years

2. Have UC diagnosed at least 3 months prior to screening? The diagnosis of UC must be confirmed by endoscopic and histologic evidence.

3. Men and women of childbearing potential must agree to use adequate birth control measures during the study.

4. Ability to provide written informed consent and to be compliant with the schedule of protocol assessments, treatment plan, laboratory tests, and other study procedures.

5. UC patients with mild, mod, severity as assess by the 4 scale assessment (Normal, mild, mod, severe).

6. Treatment naïve subjects diagnosed with ulcerative colitis (without previous exposure to treatment).

7. UC patients already on a treatment might be considered, with saffron as an add-on 8. UC patients who displayed no improvement with any available treatment might be considered for saffron as an alternative treatment in this option.

Exclusion Criteria:

1. Patients taking immunosuppressive medicine for a disease other than UC

2. Rheumatologic disease and other underlying diseases that can interfere with the study process.

3. Pregnancy

4. If the UC has been present for > 10 years, a colonoscopy with biopsy has to be performed to rule-out dysplasia.

5. A subject who had surgery as a treatment for ulcerative colitis or likely to require surgery during the study period.

6. Subjects with evidence of liver disease or abnormal liver enzymes and function tests (e.g. total bilirubin, aspartate aminotransferase (AST) or alanine aminotransferase (ALT) higher than the upper limit of normal) at the screening visit.

7. Subjects who have any condition possibly affecting oral nutritional supplement absorption.

8. Any other condition which in the opinion of the investigators would make the subject unsuitable for inclusion in the study.

9. Patients with known active or untreated GI infections including C. difficile, CMV, HSV, HIV

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	inflammatory markers assessment	Serum anti-inflammatory and pro-inflammatory markers measures in 8 weeks compared to baseline improving the blood immune marker in the normal range for contributing factors which consist of TNF-a (8.1 pg/mL).IL-1ß (<5 pg/mL), IL-6(5-15 pg/ml)., and IL-10 (4.8-9.8 pg/ml), The units in the parenthesis are the normal range for each marker	8 weeks
Primary	stool frequency assessment	will be assessed by decreasing less than 2 per day	8 week
Primary	stool consistency assessment	Improvement to median score 4 to normal stool consistency. Bristol score: Improvement in stool consistency measures in 8 weeks in our study compared to baseline (Bristol score: The ideal stool is generally type 3 or 4, easy to pass without being too watery too solid. Type 1 or 2, it is sign of constipation. Types 5, 6, and 7 tend toward diarrhea)	8 week
Primary	fecal calprotectin assessment	Decrease in calprotectin levels. Fecal calprotectin normal range to be 10 to 60 µg/mg	8 weeks
