E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
for the Treatment Cohort: The primary objective of the treatment cohort is to evaluate the safety profile of long-term vedolizumab IV treatment in pediatric subjects with UC or CD.
|
|
E.2.2 | Secondary objectives of the trial |
Secondary Objectives for the Treatment Cohort: • To evaluate the effect of long-term vedolizumab IV treatment on time to major inflammatory bowel disease (IBD)-related events (eg, hospitalizations, surgeries, and procedures) in pediatric subjects with UC or CD. • To evaluate quality of life in subjects aged 9 to 17 years who were treated with vedolizumab IV using the IMPACT-III questionnaire.
Objectives for the Observational Cohort: • The objectives for the observational cohort are to assess prespecified safety events of interest and monitor growth and pubertal development for approximately 2 years after the last dose of study drug in Studies MLN0002-3024 or MLN0002-3025. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Main Criteria for Inclusion in the Treatment Cohort: 1. In the opinion of the investigator, the subject, parent, or legal guardian is capable of understanding and complying with protocol requirements. 2. The subject, parent, or legal guardian signs and dates a written, informed consent form and any required privacy authorization before the initiation of any study procedures. 3. The subject is male or female with UC or CD and aged <18 years. (Note: Subjects who reach adult age [18 years of age in most jurisdictions/regions] during the study should be considered to transition to commercial drug if available in their country, especially if transition to an adult care setting is required by local regulation.). 4. The subject has completed Study MLN0002-3024 or Study MLN00023025 and has achieved corticosteroid-free clinical response at Week 54 (and has tapered off of steroids, as applicable, at least 12 weeks before Week 54) as defined by a reduction of partial Mayo score of ≥2 points and ≥25% from baseline for subjects with UC; or a reduction of PCDAI of ≥15 points for subjects with CD from baseline of the parent study and with total PCDAI ≤30. 5. A male subject who is sexually active with a female partner of childbearing potential agrees to use barrier method of contraception (eg, condom with or without spermicide) from signing of informed consent throughout the duration of the study and for 18 weeks after last dose. The female partner of a male subject should also be advised to use a highly effective method of contraception. 6. A female subject of childbearing potential who is sexually active with a nonsterilized male partner agrees to use a highly effective method of contraception from signing of informed consent throughout the duration of the study and 18 weeks after the last dose.
Main Criteria for Inclusion in the Observational Cohort: 7. The subject, parent, or legal guardian signs and dates a written, informed consent form. 8. The subject has received at least 1 dose of vedolizumab during Study MLN0002-3024 or Study MLN0002-3025 and early terminated OR completed the Week 54 visit of Study MLN0002-3024 or Study MLN0002-3025 but was not eligible to enroll in the treatment cohort of this study. |
|
E.4 | Principal exclusion criteria |
Treatment Cohort only: 1. The subject is female and is lactating or pregnant. 2. The subject has hypersensitivity or allergies to vedolizumab or any of its excipients. 3. The subject currently requires major surgical intervention for UC or CD (eg, bowel resection), or is anticipated to require major surgical intervention for UC or CD during the study. 4. The subject has developed any new unstable or uncontrolled cardiovascular, heart failure moderate to severe (New York Class Association III or IV), pulmonary, hepatic, renal, gastrointestinal, genitourinary, hematological, coagulation, immunological, endocrine/metabolic, neurological, or other medical disorder that, in the opinion of the investigator, would confound the study results or compromise subject safety. 5. The subject has other serious comorbidities that will limit their ability to complete the study. 6. The subject is unable to comply with all study assessments. |

E.5 End points |
E.5.1 | Primary end point(s) |
for the Treatment Cohort: The primary endpoint for this study is the incidence of adverse events (AEs).
for the Observational Cohort: Incidence of prespecified safety events (serious infections, malignancies, progressive multifocal leukoencephalopathy [PML], concerns about growth and pubertal development, and bowel surgery).
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
for the primary end point Treatment Cohort: Once every 16 weeks until Week 48, thereafter once every 24 weeks.
for the primary end point for the Observational Cohort: Incidence of prespecified safety events (serious infections, malignancies, progressive multifocal leukoencephalopathy [PML], concerns about growth and pubertal development, and bowel surgery). |
|
E.5.2 | Secondary end point(s) |
For the Treatment Cohort: • Time to major IBD-related events (eg, hospitalizations, surgeries, or procedures). • Changes from baseline of Studies MLN0002-3024 (UC) or MLN0002-3025 (CD) in IMPACT-III total and subscale scores for subjects aged 9 to 17 years as measured every 24 weeks.
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Time to major IBD-related events - through-out duration of the study. Changes from baseline of Studies MLN0002-3024 (UC) or MLN0002-3025 (CD) in IMPACT-III total and subscale scores for subjects aged 9 to 17 years as measured - every 24 weeks.
