Phase 3 Ulcerative Colitis Trials
5 Phase 3 trials for Ulcerative Colitis, the final stage before a treatment can be submitted for FDA approval.
5 Phase 3 clinical trials for Ulcerative Colitis are registered on ClinicalTrials.gov. Phase 3 is the final stage of testing before a treatment can be submitted for FDA approval, and the trials below come directly from the federal registry. Always talk to your doctor before contacting a study site.
What Phase 3 Means for Ulcerative Colitis
Phase 3 trials are the largest and most expensive stage of clinical research before potential FDA approval. For Ulcerative Colitis, a Phase 3 protocol typically enrolls several hundred to several thousand patients across many medical centers, randomizes participants between the investigational treatment and either a placebo or current standard of care (where ethically appropriate), and tracks them for months or years to confirm that the treatment is both effective and safe in a real-world patient population.
5 Phase 3 trials for Ulcerative Colitis are listed on ClinicalTrials.gov. Smaller late-stage pipelines often correspond to rare conditions, niche subpopulations, or treatment areas where Phase 2 results are still being read out.
Takeda (1), McMaster University (1), Andreas Stallmach (1) lead the Phase 3 Ulcerative Colitis sponsor list. The blend of industry, academic, and government sponsors on a condition's Phase 3 list is a useful signal of how broadly the research community is engaged with the disease.

What Participation Looks Like
Phase 3 trials for Ulcerative Colitis typically enroll several hundred to several thousand participants across multiple sites. Participation involves a screening visit to confirm eligibility, randomization to either the investigational treatment or a comparator (often the current standard of care), regular study visits over months or years, and follow-up after the active treatment period. The protocols, time commitments, and visit schedules differ from trial to trial — read the per-trial page for the specifics before discussing participation with your doctor.
Each trial begins with informed consent and a screening visit, where the study team confirms eligibility against the inclusion and exclusion criteria. Randomization assigns participants to either the investigational treatment or a comparator. Standard-of-care portions of the protocol are typically billed to insurance; trial-specific procedures (extra imaging, biopsies, lab draws beyond standard care) are usually covered by the sponsor. Read each trial\'s detailed page for its specific time commitment and visit schedule.

Frequently Asked Questions
What is a Phase 3 Ulcerative Colitis trial?
A Phase 3 trial is the final stage of clinical testing before a treatment can be submitted to the FDA for approval. For Ulcerative Colitis, Phase 3 studies typically enroll hundreds to thousands of patients across multiple medical centers, comparing the new treatment to the current standard of care or a placebo (where ethically appropriate). The goal is to confirm efficacy, monitor side effects in a larger population, and generate the evidence the FDA needs to make an approval decision.
How many Phase 3 Ulcerative Colitis trials are recruiting?
5 Phase 3 trials for Ulcerative Colitis are currently registered on ClinicalTrials.gov. Recruitment status varies by trial — some are actively enrolling, some have closed enrollment but are still in the active treatment phase, and some are completing follow-up. Click any trial below to see its current status, eligibility criteria, and contact information.
Who can participate in a Phase 3 Ulcerative Colitis trial?
Phase 3 eligibility depends entirely on the specific trial protocol. Each trial sets its own inclusion criteria (typically a confirmed diagnosis, certain disease stage or severity, age range) and exclusion criteria (often previous treatments, comorbidities, lab values that fall outside set ranges). The trial pages on this site translate the clinical eligibility criteria into plain English alongside the original text. Whether you fit any specific trial is a medical decision your doctor needs to confirm.
Is participating in a Phase 3 Ulcerative Colitis trial safe?
Phase 3 trials use treatments that have already passed Phase 1 (safety in small groups) and Phase 2 (initial efficacy and side-effect monitoring), so the safety profile is better understood than in earlier-phase studies. That said, side effects can still emerge in larger populations, and the trial protocol may require additional procedures (lab draws, imaging, biopsies) beyond standard care. The informed consent document for any specific trial details the known risks. Discuss those risks with your physician before deciding whether to participate.
Where does this trial data come from?
All trial data is sourced from the ClinicalTrials.gov API v2, the federal registry maintained by the National Library of Medicine at NIH. Under FDAAA 801, most U.S. drug and device trials must register on ClinicalTrials.gov, making it the most comprehensive source of trial information. Sponsors are required to update trial status within 30 days of a change, but delays occur — always confirm the current status with the trial site before traveling for screening.
How This Page Is Built
The trial list is filtered to ClinicalTrials.gov registrations whose phase field includes Phase 3 and whose condition list includes Ulcerative Colitis. Trial counts and the sponsor leaderboard are computed from the same record set. Plain-English eligibility translations on each linked trial page preserve the original clinical text alongside the accessible version.
