A Study of Icotrokinra in Participants With Moderately to Severely Active Crohn's Disease
(ICONIC-CD)
What this study is about
The purpose of this study is to evaluate how-well icotrokinra works (clinical effectiveness) and how safe it is (safety) in participants with moderately to severely active Crohn's disease (CD; a long-term condition causing severe inflammation of the intestinal tract).

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Diagnosis of CD established at least 12 weeks before screening including both endoscopic evidence and a histopathology report consistent with a diagnosis of CD
- Moderately to severely active CD based on CDAI criteria, defined as baseline (Week I-0) CDAI score \>=220 but \<=450 and either mean daily SF count \>=4, or mean daily AP score \>=2
- Moderately to severely active CD based on SES-CD criteria assessed by baseline (Week I-0) endoscopic evidence of active ileal and/or colonic CD as assessed during central review of the screening video ileocolonoscopy defined as a SES-CD \>= 6 for participants with colonic or ileocolonic disease, and SES-CD \>= 4 for participants with isolated ileal disease, based on the presence of ulceration in any 1 of the 5 ileocolonic segments
- A female participant of childbearing potential must have a negative highly sensitive serum pregnancy test (beta-hCG) at screening and a negative urine pregnancy test at Week I-0 prior to adminis

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
