Predicting Clinical Response to Golimumab With Mucosal Barrier Dysfunction

This is an interventional other trial for Ulcerative Colitis focused on measuring mucosal barrier function Read More

Inclusion Criteria:

1. Diagnosis of ulcerative colitis based on standard clinical, radiological, endoscopic and histological criteria with moderate-to-severe disease activity, defined as a Mayo score of 6-12, with an endoscopic subscore of 2 or more.
2. Age 18-75 years
3. Patients about to be started on golimumab therapy because of moderate to severe flare, steroid dependence, or failure of other therapies.

4. Inadequate response to or failure to tolerate 1 or more of the following conventional therapies:

   • Oral 5-aminosalicylates (5-ASAs)
   • Oral corticosteroids
   • Immunosuppressives (azathioprine (AZA) or 6-mercaptopurine) OR
   • Corticosteroid-dependent (i. e., could not taper corticosteroids without recurrence of UC symptoms) AND
   • No previous exposure to biological therapy (TNF naïve)
5. Patients concurrently treated with oral 5-aminosalicylates or corticosteroids must have maintained stable dose for ≥ 2 weeks before baseline.
6. Patients concurrently treated with AZA and/or 6-mercaptopurine must have maintained stable dose for ≥ 4 weeks before baseline.

7. Tuberculosis (TB) related screening criteria:

   1. No history of latent or active tuberculosis (TB) prior to screening. An exception is made for subjects who have a history of latent TB and are currently receiving treatment for latent TB, will initiate treatment for latent TB prior to first administration of golimumab, or have documentation of having completed appropriate treatment for latent TB within 3 years prior to the first administration of golimumab.
   2. No signs or symptoms suggestive of active TB upon medical history and/or physical examination.
   3. No recent close contact with a person with active TB or, if there has been such contact, will be referred to a physician specializing in TB to undergo additional evaluation and, if warranted, receive appropriate treatment for latent TB prior to the first administration of study agent.
   4. Within 2 months prior to the first administration of golimumab, have a negative QuantiFERON®-TB Gold test result, or have a newly identified positive QuantiFERON®-TB Gold test result in which active TB has been ruled out and for which appropriate treatment for latent TB has been initiated prior to the first administration of study agent. Subjects with persistently indeterminate QuantiFERON®-TB Gold test results may be enrolled without treatment for latent TB, if active TB is ruled out, their chest radiograph shows no abnormality suggestive of TB (active or old, inactive TB), and the subject has no additional risk factors for TB as determined by the principal investigator.
   5. Have a chest radiograph posterior-anterior views, taken within 3 months prior to the first administration of study agent and read by a qualified radiologist, with no evidence of current, active TB or old, inactive TB.

Exclusion Criteria:

1. Pregnancy/nursing.
2. Known allergies to IV contrast or shellfish.
3. Impaired renal function (serum creatinine over 1.5 mg/dL).
4. Uncontrolled or severe asthma.
5. Active infection.
6. Active or previously identified latent tuberculosis.
7. History of systemic lupus.
8. Current or history of demyelinating neurological disease.
9. Current or history of congestive heart failure.
10. History of or at imminent risk for colectomy.
11. Gastrointestinal surgery ≤ 2 months prior to screening for study entry.
12. Colitis limited to 20 cm. of the colon.
13. History of colonic mucosal dysplasia or adenomatous colonic polyps that were not removed.
14. Screening stool sample positive for enteric pathogens or Clostridium difficile toxin.

15. Previous use of the following medications:

    • Biologic anti-TNF agent(s) natalizumab or other agents targeting the α-4integrin, B-cell-depleting agents (rituximab) or T-cell-depleting agents (vedolizumab, visilizumab) within 12 months of study entry.
    • Continued B- or T-cell depletion ˃ 12 months after completing therapy with lymphocyte-depleting agents.
    • Oral corticosteroids at a dose ˃ 40 mg. prednisone or its equivalent per day
    • Use of cyclosporine, tacrolimus, sirolimus, or mycophenolate mofetil within 8 weeks of study entry.
    • Use of an investigational agent within 5 half-lives of that agent prior to study entry.
16. History of any malignancy.
17. History of active granulomatous infection, including histoplasmosis or coccidioidomycosis, prior to screening.

18. Subjects must undergo screening for hepatitis B virus (HBV). At a minimum, this includes testing for HBsAg (HBV surface antigen), anti-HBs (HBV surface antibody), and anti-HBc total (HBV core antibody total):

    1. Subjects who test negative for all HBV screening tests (ie, HBsAg-, anti-HBc-, and anti HBs-) are eligible for this study.
    2. Subjects who test positive for surface antigen (HBsAg+) are not eligible for this study, regardless of the results of other hepatitis B tests.
    3. Subjects who test negative for surface antigen (HBsAg-) and test positive for core antibody (anti-HBc+) and surface antibody (anti-HBs+) are eligible for this study.
    4. Subjects who test positive only for surface antibody (anti-HBs+) are eligible for this study.
    5. Subjects who test positive only for core antibody (anti-HBc+) must undergo further testing for hepatitis B deoxyribonucleic acid (HBV DNA test). If the HBV DNA test is positive, the subject is not eligible for this study. If the HBV DNA test is negative, the subject is eligible for this study. In the event the HBV DNA test cannot be performed, the subject is not eligible for this study.

1. Subjects with a positive HBV DNA test will be counselled per the clinical Hepatitis B Positive Screen Standard Operating Procedure (SOP). If the HBV DNA test cannot be performed, the subject will be counselled per the SOP at the physician's discretion.

19. Have had a Bacille Calmette-Guérin (BCG) vaccination within 12 months of screening.

20. Have a chest radiograph within 3 months prior to the first administration of golimumab that shows an abnormality suggestive of a malignancy or current active infection, including TB.

21. Have had a nontuberculous mycobacterial infection or opportunistic infection (e. g., cytomegalovirus, pneumocystosis, aspergillosis) within 6 months prior to screening.
