Study to Evaluate the Safety, Efficacy, and Pharmacokinetics of Budesonide Extended-release Tablets in Pediatric Subjects Aged 5 to 17 Years With Active, Mild to Moderate Ulcerative Colitis

A Randomized, Double-blind, Placebo-controlled, Multicenter Study to Evaluate the Safety, Efficacy, and Pharmacokinetics of Budesonide Extended-release Tablets n Pediatric Subjects Aged 5 to 17 Years With Active, Mild to Moderate Ulcerative Colitis

This is a randomized, double-blind, placebo-controlled, multicenter, study to evaluate the efficacy, safety, and pharmacokinetics (PK) of budesonide extended-release tablets for the induction of remission in pediatric subjects, with active, mild to moderate ulcerative colitis (UC). Subjects will be permitted to continue taking background oral or rectal 5-aminosalicylate (5-ASA) products.

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 5 years to 17 years (Child)
• Accepts Healthy Volunteers: No

Description

Inclusion Criteria:

• Established diagnosis of UC is based on:

  • Clinical history
  • Characteristic endoscopic findings
  • Histopathology results from biopsies
• Age 5 to 17 years, inclusive, at Screening. Subjects should weigh greater than 13.6 kg at Baseline.
• Active UC of mild or moderate severity, defined as a total Mayo score between 4 and 10, inclusive, with rectal bleeding subscore of ≥ 1, stool frequency subscore of ≥1 and an endoscopy subscore of ≥ 1.
• If on a background oral or rectal 5-ASA, the dose and formulation have remained unchanged for at least 6 weeks prior to Visit 2 (randomization), Baseline and the subject is willing to remain on the same formulation and dose for the duration of the study.

Exclusion Criteria:

1. Current or prior diagnosis of Crohn's disease or indeterminate colitis.
2. Limited distal proctitis (disease involving only the first 15 centimeters or less proximal to the anal verge.
3. Severe UC, defined as total Mayo score >10.
4. Not currently in an active phase or flare, defined as a total Mayo score <4, or Mayo score between 4 and 10, but Mayo subscore of 0 for rectal bleeding, stool frequency or endoscopy.
5. Infectious colitis (based on positive microbiologic tests at Screening) or any recent history of infectious colitis (within 30 days prior to Screening).

6. Prior gastrointestinal surgery, except appendectomy or hernia (e.g., inguinal, umbilical).

   NOTE: Prior cholecystectomy is not exclusionary if more than 1 year prior to Screening.

7. Evidence or history of toxic megacolon or bowel resection.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The primary efficacy endpoint is the proportion of subjects who achieve clinical remission at Day 56, defined as a total Mayo score of ≤ 1 with subscores of 0 for both rectal bleeding and stool frequency, and a subscore of ≤ 1 for endoscopy.	The primary efficacy endpoint is the proportion of subjects who achieve clinical remission at Day 56, defined as a total Mayo score of ≤ 1 with subscores of 0 for both rectal bleeding and stool frequency, and a subscore of ≤ 1 for endoscopy. The Mayo score is a composite index score based on 4 components: stool frequency (subject reported), rectal bleeding (subject reported), findings of endoscopy, and the physician's rating of disease activity. Each component is scored from 0 to 3, with total scores range from 0 to 12 with higher scores indicating more severe disease.	56 days

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Proportion of subjects who achieve a Mayo rectal bleeding subscale score of 0 at Day 56.	Proportion of subjects who achieve a Mayo rectal bleeding subscale score of 0 at Day 56. The Mayo score is a composite index score based on 4 components: stool frequency (subject reported), rectal bleeding (subject reported), findings of endoscopy, and the physician's rating of disease activity. Each component is scored from 0 to 3, with total scores range from 0 to 12 with higher scores indicating more severe disease.	56 days
