Mitä tutkimuksessa mitataan?

Ensisijaiset tulostoimenpiteet

Tulosmittaus
Toimenpiteen kuvaus
Aikaikkuna
Co-Primary: Percentage of Participants with Clinical Remission at Week 48
Aikaikkuna: At Week 48
Clinical remission is defined as a Crohn's Disease Activity Index (CDAI) score less than (<) 150. CDAI scores range from 0 to approximately 600. Higher score indicates higher disease activity.
At Week 48
Co-Primary: Percentage of Participants with Endoscopic Remission at Week 48
Aikaikkuna: At Week 48
Endoscopic remission is defined as a Simple Endoscopic Score for Crohn's Disease (SES-CD) score of less than or equal to (<=) 4 with at least a 2-point reduction from baseline and no subscore greater than (>) 1 in any individual component. The SES-CD is based on the evaluation of 4 endoscopic components (presence/size of ulcers, proportion of mucosal surface covered by ulcers, proportion of mucosal surface affected by any lesions, and presence/type of narrowing/strictures) across 5 ileocolonic segments. SES-CD score can range from 0 to 56. Higher scores indicating more severe disease.
At Week 48

Tulosmittaus
Toimenpiteen kuvaus
Aikaikkuna
Percentage of Participants with Deep Remission at Week 48
Aikaikkuna: At Week 48
Deep remission (composite endpoint) is defined as achieving both clinical remission and endoscopic remission at Week 48 at the participant level. Clinical remission is defined as a CDAI score of <150 and Endoscopic remission is defined as a SES-CD score of <= 4 with at least a 2-point reduction from baseline and no subscore >1 in any individual component. CDAI scores range from 0 to approximately 600. Higher score indicates higher disease activity. SES-CD score can range from 0 to 56. Higher scores indicating more severe disease.
At Week 48
Percentage of Participants with Corticosteroid-Free (90-Day) Clinical Remission at Week 48
Aikaikkuna: At Week 48
Corticosteroid-free (90-day) clinical remission at Week 48 is defined as clinical remission at Week 48 and not receiving corticosteroids for at least 90 days prior to Week 48. Clinical remission is defined as a CDAI score of <150. CDAI scores range from 0 to approximately 600. Higher score indicates higher disease activity.
At Week 48
Percentage of Participants with Corticosteroid-Free (90-day) PRO-2 Remission at Week 48
Aikaikkuna: At Week 48
Corticosteroid-free (90-day) patient-reported outcome(s) (PRO-2) remission at Week 48 is defined as an abdominal plan (AP) mean daily score less than or equal to (<=) 1 and stool frequency (SF) mean daily score <= 2.8, and no worsening of AP or SF from baseline, and not receiving corticosteroids for at least 90 days prior to Week 48.
At Week 48
Percentage of Participants with Sustained Clinical Remission
Aikaikkuna: At Weeks 12 and 48
Sustained clinical remission is defined as clinical remission at Week 12 and Week 48. Clinical remission is defined as CDAI score of <150. CDAI scores range from 0 to approximately 600. Higher score indicates higher disease activity.
At Weeks 12 and 48
Percentage of Participants with Histologic-Endoscopic Remission at Week 48
Aikaikkuna: At Week 48
Histologic-endoscopic remission at week 48 is defined as achieving a combination of histologic remission and endoscopic remission at Week 48. Histologic remission is defined as absence of neutrophils from the mucosa (both lamina propria and epithelium), no crypt destruction, and no erosions, or ulcerations or granulation tissue as assessed by the Robarts Histopathology Index. Endoscopic remission is defined as a SES-CD score of <= 4 with at least a 2-point reduction from baseline and no subscore > 1 in any individual component.
At Week 48
Percentage of Participants with Inflammatory Bowel Disease Questionnaire (IBDQ) Response at Week 48
Aikaikkuna: At Week 48
IBDQ response at Week 48 is defined as an improvement of at least 16 points in the IBDQ total score from baseline at Week 48. IBDQ is a validated, 32-item, self-reported questionnaire for participants with IBD that will be used to evaluate disease-specific health related quality of life (HRQoL) across 4 dimensional scores: bowel symptoms (loose stools, AP), systemic function (fatigue, altered sleep pattern), social function (work attendance, need to cancel social events), and emotional function (anger, depression, irritability). Scores range from 32 to 224, with higher scores indicating better outcomes.
At Week 48
Percentage of Participants with Patient-Reported Outcomes Measurement Information System 29 (PROMIS-29) Mental Component Summary Score (MCS) Response at Week 48
Aikaikkuna: At Week 48
PROMIS-29 MCS response at Week 48 is defined as an improvement of at least 7 points in PROMIS-29 MCS score from baseline at Week 48. The PROMIS-29 is a collection of short forms containing 4 items for each of 7 domains (depression, anxiety, physical function, pain interference, fatigue, sleep disturbance, and ability to participate in social roles and activities). PROMIS-29 also includes an overall average pain intensity 0-10 numeric rating scale. The PROMIS-29 MCS will be assessed, which is primarily informed by domains of emotional distress (depression/anxiety) and fatigue as well as sleep disturbance where higher MCS scores reflect better mental health.
At Week 48
Percentage of Participants with Clinical Remission at Week 12
Aikaikkuna: At Week 12
Clinical remission at Week 12 is defined as CDAI score <150 at Week 12. CDAI scores range from 0 to approximately 600. Higher score indicates higher disease activity.
At Week 12
Percentage of Participants with Endoscopic Response at Week 12
Aikaikkuna: At Week 12
Endoscopic response at Week 12 is defined as greater than (>) 50 percent (%) improvement from baseline in SES-CD score at Week 12 or a decrease of at least 2 points in participants with a baseline score of 4 and isolated ileal disease. SES-CD score can range from 0 to 56. Higher scores indicating more severe disease.
At Week 12
Number of Participants with Adverse Events (AE) and Serious AEs (SAEs)
Aikaikkuna: Up to approximately 3 years
An AE is any untoward medical occurrence in a clinical study participant administered a pharmaceutical (investigational or non investigational) product. An AE does not necessarily have a causal relationship with the intervention. An SAE 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, is a congenital anomaly/birth defect, is a suspected transmission of any infectious agent via a medicinal product, and is medically important.
Up to approximately 3 years
