Clinical trial
Personalized AZithromycin/metronidAZole, in Combination With Standard Induction Therapy, to Achieve a Fecal Microbiome Community Structure and Metagenome Changes Associated With Sustained Remission in Pediatric Crohn's Disease (CD): a Pilot Study
Name
19-3100
Description
This is a multi-center, randomized, controlled open-label add-on design trial pilot study to evaluate the efficacy of personalized adjunctive antibiotic (azithromycin + metronidazole) therapy in pediatric subjects with mild to moderate Crohn's disease (CD) who have a microbiome profile associated with increased risk of early relapse. This an add-on design trial for subjects already receiving standard of care therapy to induce remission; there will be no placebos.

Eligibility criteria
Inclusion Criteria:
1. Provision of signed and dated informed consent form (and assent form, as applicable);
2. Stated willingness to comply with all study procedures and availability for the duration of the study;
3. Male or female, aged 3 to 17 years;
4. Diagnosed with CD according to standard clinical and histological criteria, within 36 months of week 0;
5. Exhibiting mild to moderate symptoms of active disease, as determined by a PCDAI score \>10 (or \> 7.5 excluding the height item) and ≤37.5;
6. Fecal calprotectin level \>=250 µg/g within 30 days prior to week 0 visit based on local measurement, if available, or to be arranged with lead site if an endoscopy is not performed within 30 days prior to week 0 visit.
Exclusion Criteria:
1. Current or previous use of biologic therapy;
2. Presence of stricturing, penetrating (intestinal or perianal) and/or fistulizing CD;
3. Pregnancy or lactation;
4. Have undergone intestinal resection;
5. Positive Clostridium Difficile toxin;
6. Treatment with another investigational drug or other intervention within 30 days before week 0;
7. Risk factors for arrhythmia including history of prolonged corrected QT interval (QTc), hypokalemia or hypomagnesemia, resting bradycardia, or concurrent treatment with other drugs with potential for QT prolongation;
8. History of cockayne syndrome;
9. Prior diagnosis of any hematologic condition/blood dyscrasia which may result in leukopenia (even if leukocyte count is normal at screening);
10. Known allergy or intolerance to azithromycin or metronidazole;
11. Subjects who received intravenous anti-infective within 35 days prior to week 0 visit or anti-infectives within 14 days prior to the week 0 visit;

* White blood cell (WBC) count \< 3.0 X 109/L,
* Total bilirubin \>= 20 micromol/liter (1.17 mg/dL); except for subjects with isolated elevation of indirect bilirubin relating to Gilbert syndrome,
