| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Certolizumab pegol low dose arm | Experimental | Participants randomized to certolizumab pegol (CZP) who weigh ≥17 kg to <40 kg will receive placebo at Week 0 and a loading dose of 200 mg at Weeks 0, 2, and 4, followed by a maintenance dose of 100 mg CZP subcutaneously (sc) every 2 weeks (Q2W). Participants randomized to CZP who weigh ≥40 kg will receive placebo at Week 0 and a loading dose of 400 mg at Weeks 0, 2, and 4, followed by placebo and a maintenance dose of 200 mg CZP sc Q2W. |
|
| Certolizumab pegol high dose arm | Experimental | Participants randomized to CZP who weigh ≥17 kg to <40 kg will receive placebo at Week 0 and a loading dose of 200 mg at Weeks 0, 2, and 4, followed by a maintenance dose of 200 mg CZP sc Q2W. Participants randomized to CZP who weigh ≥40 kg will receive placebo at Week 0 and a loading dose of 400 mg at Weeks 0, 2, and 4, followed by a maintenance dose of 300 mg CZP sc Q2W. |
|
| Adalimumab reference arm | Active Comparator | Participants randomized to adalimumab who weigh ≥17 kg to <40 kg will receive a loading dose of 80 mg at Week 0 and 40 mg at Week 2, followed by a maintenance dose of 20 mg sc Q2W. Participants randomized to Adalimumab who weigh ≥40 kg will receive a loading dose of 160 mg at Week 0 and 80 mg at Week 2, 40 mg and placebo at week 4 followed by a maintenance dose of 40 mg sc and placebo Q2W. |

| Clinical remission based on total Pediatric Crohn's Disease Activity Index (PCDAI) score ≤10.0 points at Week 26 | Clinical remission is defined as a Pediatric Crohn's Disease Activity Index (PCDAI) score ≤ 10. The Pediatric Crohn's Disease Activity Index (PCDAI) consists of 4 domains (laboratory, height/weight, examination, and history) with several assessments that are converted into a total PCDAI score which can range from 0 to 100 points, with a higher score indicating more severe disease activity. | Week 26 |
| Measure | Description | Time Frame |
|---|---|---|
| Clinical remission (modified) at Week 26 | Clinical remission (modified) is defined as a Pediatric Crohn's Disease Activity Index (PCDAI) score ≤ 10 and the abdominal pain and stool frequency items in the PCDAI having scores of 0. The Pediatric Crohn's Disease Activity Index (PCDAI) consists of 4 domains (laboratory, height/weight, examination, and history) with several assessments that are converted into a PCDAI score which can range from 0 to 100 points, with a higher score indicating more severe disease activity. |

Data from this trial may be requested by qualified researchers six months after product approval in the US and/or Europe, or global development is discontinued, and 18 months after trial completion. Investigators may request access to anonymized individual patient-level data and redacted trial documents which may include: analysis-ready datasets, study protocol, annotated case report form, statistical analysis plan, dataset specifications, and clinical study report. Prior to use of the data, proposals need to be approved by an independent review panel at www.Vivli.org and a signed data sharing agreement will need to be executed. All documents are available in English only, for a prespecified time, typically 12 months, on a password protected portal. This plan may change if the risk of re-identifying trial participants is determined to be too high after the trial is completed; in this case and to protect participants, individual patient-level data would not be made available.

| Adalimumab | Drug |
Subjects will receive adalimumab in a pre-specified sequence during the Treatment Periods. |
|
| Placebo | Drug |
Subjects will receive placebo in a pre-specified sequence during the Treatment Periods. |
|
| Week 26 |
| Corticosteroid-free clinical remission at Week 26 | Corticosteroid free clinical remission is defined as not taking corticosteroids after tapering, within 4 weeks prior to Week 26, and total PCDAI score ≤10.0 points and the abdominal pain and stool frequency items in the PCDAI having scores of 0 at Week 26. | Week 26 |
| Clinical response at Week 26 and Week 52 | Clinical response is defined as a decrease from Week 0 in Pediatric Crohn's Disease Activity Index (PCDAI) score of ≥ 15 points and a total PCDAI score ≤ 30 points. The Pediatric Crohn's Disease Activity Index (PCDAI) consists of 4 domains (laboratory, height/weight, examination, and history) with several assessments that are converted into a PCDAI score which can range from 0 to 100 points, with a higher score indicating more severe disease activity. | Week 26; Week 52 |
| Endoscopic remission at Week 26 | Endoscopic remission is defined as Simple Endoscopic Score for Crohn's Disease [SES-CD] from 0 to 2, with a higher score indicating more disease activity. SES-CD is based on four endoscopic variables (presence and size of ulcers, proportion of surface covered by ulcers, proportion of surface affected by disease, and presence and severity of stenosis). Each of the four SES-CD variables is scored from 0 to 3, with the sum of the scores for each variable ranging from 0 to 15, except for the presence and extent of stenosis, which ranges from 0 to 11, yielding a total SES-CD score of 0-56. | Week 26 |
| Clinical remission based on total PCDAI score ≤10.0 points at Week 52 | Clinical remission is defined as a Pediatric Crohn's Disease Activity Index (PCDAI) score ≤ 10. The Pediatric Crohn's Disease Activity Index (PCDAI) consists of 4 domains (laboratory, height/weight, examination, and history) with several assessments that are converted into a total PCDAI score which can range from 0 to 100 points, with a higher score indicating more severe disease activity. | Week 52 |
| Clinical remission (modified) at Week 52 | Clinical remission (modified) is defined as a Pediatric Crohn's Disease Activity Index (PCDAI) score ≤ 10 and the abdominal pain and stool frequency items in the PCDAI having scores of 0. The Pediatric Crohn's Disease Activity Index (PCDAI) consists of 4 domains (laboratory, height/weight, examination, and history) with several assessments that are converted into a PCDAI score which can range from 0 to 100 points, with a higher score indicating more severe disease activity. | Week 52 |
| Incidence of serious Treatment Emergent Adverse Event (TEAEs) | A Serious Treatment Emergent Adverse Event is any untoward medical occurrence that at any dose:
| From Baseline to the Safety Follow-Up visit (Week 166) |
| Incidence of TEAEs leading to permanent withdrawal of investigational medicinal product | An Adverse Event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. | From Baseline to the Safety Follow-Up visit (Week 166) |
