Details and patient eligibility

About

To date, there are no reports on the use of QD in pediatric patients with UC. There is a great need to increase the repertoire of anti-inflammatory interventions for remission induction, especially in children given the notorious side effects of steroids on growth. Importantly, no prescription is needed to acquire QD, as this is a food supplement that can be purchased over the counter. We wish to assess the efficacy and safety of QD as induction therapy in pediatric patients with mild-moderate active UC.

Full description

This is a prospective open-label pilot study in two Pediatric IBD centers at Schneider Children's Medical Center of Israel and Share Zedek Medical Center. Pediatric UC patients at both participating centers will be screened during clinic visits for eligibility to participate in the study. Eligible patients are 4-17.9 years old, with at least one month history of UC, with mild to moderate active UC, defined by a PUCAI score of 10-60, despite current treatment. Normal liver enzymes obtained within one most prior to initiation of the study is required. The study will be presented to the families and once it is established that the patient fulfills the inclusion criteria, informed written consent will be obtained from the patient and parents.

Enrollment:

At enrolment patients will be examined and explicit clinical, medical and demographic data will be documented. PUCAI16 and TUMMY-UC (patient reported outcome developed specifically for pediatric UC patients17) scores will be determined. Extent of disease will be documented according to the last available colonoscopy, using the Montreal classification definitions (additional endoscopic evaluation is not required for the study). Laboratory work including CBC, albumin, AST, ALT, ESR and CRP. A stool sample will be obtained and kept at -800C for future analyses (see below). In addition, a baseline echocardiography will be performed to assess for PAH prior to initiation of QD (see below). Patients of child bearing potential will be advised to safeguard against pregnancy.

Following completion of enrollment and initial testing patients will receive QD (see dosing regimens below). QD will be provided as oral capsules. Patients who are not able to swallow the capsules will be instructed to open then and give it with yogurt/soft food. Patients will be instructed to continue taking their maintenance medication as prescribed by their treating physician throughout the entire study period, without any changes.

Day 3-4:

Patients will be contacted via telephone and questioned regarding any adverse effects, and specifically headaches, along with colitis-associated clinical features.

Week 3:

Patients will be seen in clinic, and will also be examined, as part of routine clinical care. Clinical data will be obtained, including PUCAI and TUMMY-UC. Prior to this visit, patients will complete blood work including CBC, chemistry panel and CRP. A stool sample will be collected at this clinic visit.

Week 6:

Patients will be seen in clinic, and will also be examined, as part of routine clinical care. Clinical data will be obtained, including PUCAI and TUMMY-UC. Patients will also complete prior to this visit blood work including CBC, chemistry panel and CRP. An additional stool sample will be obtained and kept at -80 degrees celsius for future analyses. Finally, a repeated echocardiography will be completed. At this timepoint, the study will be completed.

Termination visit:

If the study will be terminated prior to completion of the 6 weeks of QD therapy (see criteria below) the patient will be seen in clinic for a "termination visit". In this visit clinical data will be obtained, including PUCAI and TUMMY-UC. Patients will also complete prior to this visit blood work including CBC, chemistry panel and CRP. An additional stool sample will be obtained and kept at -80 degrees celsius. for future analyses.

At each study visit, patients of child bearing potential will be asked if they are pregnant.

Experimental group

Description:

Patients will be receiving QD as oral capsules. Dosing of QD will be stratified based on body weight at time of enrollment: * 15-30kg: 500 mg/day (250 mg morning; 250 mg evening). * 30-40kg: 750 mg/day (500 mg morning; 250 mg evening). * \>40kg: 1000mg/day (500 mg morning; 500 mg evening). If the patient fails to respond by week 3 to current dosing regimens (failure defined as \<20 decrease in PUCAI and PUCAI\>10), and if no safety concerns arise at week 3, dose will be increased, as following: * 15-30kg: 1000 mg/day (500 mg morning; 500 mg evening) * 30-40kg: 1500 mg/day (1000 mg morning; 500 mg evening) * \>40kg: 2000mg/day (1000 mg morning; 1000 mg evening)
