NSCIBD Clinical Studies

DUET-CD (Crohn's)/DUET-UC (Ulcerative Colitus)

The purpose of the DUET-CD/DUET-UC study is to see if the combination of guselkumab and golimumab is safe and effective for treating patients with moderately to severely active Crohn’s disease/ Ulcerative Colitis. We are looking for participants who have had a diagnosis of moderate to severe Crohn’s Disease or Ulcerative Colitis for at least three months.

The treatments being studied in this clinical trial are called guselkumab, golimumab and a combination of both currently known as JNJ-7893480.

Guselkumab works by blocking an inflammatory protein made by the immune cells called interleukin (IL)-23 and Golilumab works by blocking an inflammatory protein made by immune cells called tumor necrosis factor (TNF). JNJ-78934804 works by blocking both IL-23 and TNF.

It has been proposed that combination therapies, such as JNJ-78934804 may be more effective in inducing and maintaining remission in Crohn’s Disease/Ulcerative Colitis than monotherapies (one treatment).

Inclusion Criteria:

• Diagnosis of Crohn's disease (CD) or Ulcerative Colitis (UC) for at least 3 months prior to baseline
• Confirmed diagnosis of moderate to severe CD/UC as assessed by Crohn's disease activity index (CDAI), stool frequency (SF), abdominal pain (AP) score and simple endoscopic score for Crohn's disease (SES-CD)
• Demonstrated inadequate response, loss of response, or intolerance to at least one biologic approved for the treatment of Crohn's disease/Ulcerative Colitis (UC)
• If female and of childbearing potential, must meet the contraception and reproduction requirements

Exclusion Criteria:

• Complications of CD/UC that may be anticipated to require surgery
• Currently has or is suspected to have an abscess. Recent cutaneous and perianal abscesses are not exclusionary if drained and adequately treated at least 3 weeks before baseline, or 8 weeks before baseline for intra-abdominal abscesses, provided that there is no anticipated need for any further surgery
• Has had any kind of bowel resection within 24 weeks, or any other intra-abdominal or other major surgery within 12 weeks
• Has a draining (example, functioning) stoma or ostomy
• Currently has a malignancy or has a history of malignancy within 5 years before screening (with the exception of a nonmelanoma skin cancer or cervical carcinoma in situ that has been adequately treated with no evidence of recurrence for greater than or equal do (>=) 12 months before the first dose of study intervention)
• Has a history of, or ongoing, chronic or recurrent infectious disease, including but not limited to, sinopulmonary infections, bronchiectasis, recurrent renal/urinary tract infections (example, pyelonephritis, cystitis), an open, draining, or infected skin wound, or an ulcer
