Crohn's Disease
Conditions
Brief summary
The purpose is to determine whether RPC1063 is effective in the treatment of Crohn's disease.
Detailed description
This open-label trial is composed of two periods: Induction and Extension. All eligible patients will be enrolled into the 12-Week Induction period and receive study medication. Patients who complete the Induction period may then be eligible to enter the 100-Week Extension period where they will continue to receive study medication.

| Change in Simple Endoscopic Score for Crohn's Disease (SES-CD) (Paired Segments) From Baseline at Week 12 as Determined by a Blinded Central Reader. | Baseline to Week 12 | The simple endoscopy score (SES-CD) assesses the degree of inflammation. The SES-CD assesses the following 4 components: size of ulcers, ulcerated surface, affected surface, and presence of narrowing. Each of these components are scored on a scale of 0 to 3. In the SES-CD, each of these 4 components are assessed in the five segments of the ileum and colon: ileum, right, transverse, left (descending and sigmoid), and rectum. The SES-CD is the sum of the individual scores of each of the components across the five segments. The range of SES-CD scores is 0 - 12 for each segment, and 0 - 56 for the overall SES-CD score, with larger scores indicating greater severity of disease. |

| The Number of Participants With Treatment Emergent Adverse Events (TEAE) During the Induction and Extension Period | From the first day of ozanimod up to 90 days after the last dose of ozanimod; mean duration of exposure of study drug was 1.305 years | A TEAE = any event with an onset date on or after the first dose date, or any ongoing event on the first dose date that worsens in severity or after the first dose date and until 90 days following the last dose of study drug treatment. An AE = untoward medical occurrence in a patient or clinical investigation patient administered a pharmaceutical product, which that does not necessarily have a causal relationship with the investigational treatment. An AE can be any unfavorable or unintended sign, symptom, or disease temporally associated with the use of an investigational medicinal product, whether or not considered related to the investigational medicinal product. A serious AE (experience) or reaction is any untoward medical occurrence that at any dose * Results in death * Is life-threatening * Requires inpatient hospitalization or prolongation of existing hospitalization * Results in persistent or significant disability/incapacity, or * Is a congenital abnormality/birth defect |

Outcome results
Change in Simple Endoscopic Score for Crohn's Disease (SES-CD) (Paired Segments) From Baseline at Week 12 as Determined by a Blinded Central Reader.
The simple endoscopy score (SES-CD) assesses the degree of inflammation. The SES-CD assesses the following 4 components: size of ulcers, ulcerated surface, affected surface, and presence of narrowing. Each of these components are scored on a scale of 0 to 3. In the SES-CD, each of these 4 components are assessed in the five segments of the ileum and colon: ileum, right, transverse, left (descending and sigmoid), and rectum. The SES-CD is the sum of the individual scores of each of the components across the five segments. The range of SES-CD scores is 0 - 12 for each segment, and 0 - 56 for the overall SES-CD score, with larger scores indicating greater severity of disease.
Time frame: Baseline to Week 12
Population: The intent to treat population = all enrolled participants who received at least one dose of ozanimod. For paired segment scores, any missing segment scores, were imputed by non-missing score used in previous visit. Analysis for change from baseline includes those with data available at baseline and visit.
