Brief Summary

The ReDUCE Trial is a multinational single-blinded randomized controlled trial in mild to moderate flare of Ulcerative colitis (UC) disease patients. The purpose of the study is to validate the clinical efficacy of the UCED (Ulcerative colitis Exclusion Diet) with partial enteral nutrition (PEN) using a novel formula. The investigators anticipate that adding a novel specifically designed dietary intervention in addition to drug will lead to superior remission and mucosal healing via changes in the microbiome.

Study Arms (2)

Ulcerative colitis Exclusion Diet + Partial enteral nutrition

EXPERIMENTAL

Participants in Group 1 will receive the UCED combined with partial enteral nutrition (PEN) using a novel nutritional formula for 6 weeks (diet phase 1) that will add to oral budesonide 9 mg topical therapy for 6 weeks and will follow diet + PEN (phase 2: wk6-wk12) and diet phase 3 for 24 weeks.

Other: Ulcerative colitis Exclusion DietOther: Partial enteral nutrition (PEN)Drug: Oral Budesonide

Free diet

ACTIVE COMPARATOR

Participants in Group 2 will receive oral budesonide 9 mg topical therapy alone for 6 weeks with no dietary intervention

Other: free dietDrug: Oral Budesonide

Interventions

a limited whole food diet (UCED)

Also known as: UCED
Ulcerative colitis Exclusion Diet + Partial enteral nutrition

The diet will be supplemented by 3 glasses a day (750 m"l) of the formula developed for UC using the UCED principles.
