PATHFINDER: Evaluating the Optimal First-Line Treatment Strategy for Moderate-to-Severely Active Ileal-dominant Crohn's Disease

Korábbi kezelés

• CD-related complications such as symptomatic, endoscopically impassable strictures or abscesses that require imminent surgery (at investigator's discretion)
• Recent bowel resection <3 months before screening
• Active chronic or acute infections requiring treatment with systemic antibiotics, antivirals, antifungals, antiparasitics, or antiprotozoals during the screening period
• Not willing to withhold protocol-prohibited medications during the trial, or planned or anticipated use of any prohibited medications during screening
• Received previously or currently receiving a TNF antagonist, anti-integrin, monoclonal antibody targeting IL-12/23 or IL-23, Janus kinase (JAK) inhibitors, or sphingosine 1 phosphate (S1P) receptor modulators (irrespective of indication)

Más betegség

• Condition(s) for which the biologics included in this study is contraindicated
• Participants with current or history of colonic dysplasia or neoplasia, toxic megacolon, or fulminant colitis
• Active enteric infection (positive stool culture), including but not limited to bacterial (including C. difficile), viral, or parasitic enteric infections
• Known active hepatitis B, hepatitis C, or human immunodeficiency virus infection
• Active COVID-19 infection during the screening period
• Tested positive as part of SOC for tuberculosis (TB) at screening by QuantiFERON® TB Gold Test, tuberculin skin test, or history of untreated latent or active TB
• History of malignancy within 5 years of screening, except fully treated carcinoma in-situ of the cervix, fully treated and resolved nonmetastatic squamous or basal cell carcinoma of the skin
• Serious underlying disease other than CD that, in the opinion of the investigator, may interfere with the participant's ability to participate fully in the study
• History of alcohol or drug abuse that, in the opinion of the investigator, may interfere with the participant's ability to comply with the study procedures

Egyéb

• Pregnancy or breastfeeding

• Male or nonpregnant, nonlactating females, 18 years of age or older. Females of childbearing potential must have a negative serum or urine pregnancy test prior to randomization
• Established CD diagnosis by conventional criteria
• Baseline colonoscopy within 3 months of the first day of the screening period, with photo or video documentation of at least one large ileal ulcer >5 mm and ileal segment SES-CD ≥4 (eligibility will be determined by local endoscopist, with subsequent confirmation by a CR at a later time, post enrolment)
• Biologic-treatment naïve for CD-related therapies
• Would otherwise have been eligible to start a biologic for moderate-to-severely active CD as part of their routine clinical care and for whom there is equipoise around which biologic class to start
• Willing and able to participate fully in all aspects of this clinical trial, including adherence to study protocol and treatment algorithm
• Written informed consent must be obtained and documented
