- hypothesisThis is an exploratory study to assess changes in blood, stool and colonic inflammation after 8 weeks of treatment with tofacitinib (XELJANZ) 10 mg BID in patients with moderate to severely active UC
- Healt Condition(s) or Problem(s) studiedUlcerative Colitis
- Inclusion criteria1. Subject must be at least 18 years of age.
2. Males and females with a documented diagnosis of UC ≥ 4 months prior to entry into the study. A biopsy report supporting the diagnosis must be available in the source documents.
3. Subjects with moderately to severely active UC as defined by a total Mayo score of ≥6, with a rectal bleeding score of ≥ 1 and an endoscopic (sigmoidoscopy) subscore of ≥ 2 on the Mayo score determined within 7 days of starting the study treatment (tofacitinib).
4. Subjects must have failed or be intolerant (discontinued the medication due to an adverse event as determined by the investigator) of at least one of the following treatments for UC:
- Oral corticosteroids
- Azathioprine or 6-mercaptopurine (6-MP).
- Anti-TNF therapy: infliximab, adalimumab or golimumab.
5. No evidence of active or latent or inadequately treated infection with Mycobacterium tuberculosis (TB) as defined by negative QuantiFERON-TB Gold (QFT-G) test and a chest radiograph, taken at or within the 3 months prior to a given screening visit, without changes suggestive of active TB infection as determined by a qualified radiologist.

6. If a subject has previously received an adequate course of therapy for either latent (9 months of isoniazid in a locale where rates of primary multi-drug TB resistance are <5% or an acceptable alternative regimen) or active (acceptable multi-drug regimen) TB infection, neither a QFT-G test nor a PPD test is needed, but a chest radiograph must still be obtained if not performed within 3 months prior to a given Screening visit. Documentation of adequate treatment for TB will be obtained prior to first dose of study drug.

- A subject who is currently being treated for active TB infection is to be excluded.

- A subject who is currently being treated for latent TB infection can only be enrolled with confirmation of current incidence rates of multi-drug resistant TB infection in the locale, documentation of an adequate treatment regimen, and with prior approval by the sponsor (AMC) .

7. Female subjects of childbearing potential must agree to use a highly effective method of contraception throughout the study and for at least 4 weeks after the last dose of assigned treatment. A subject is of childbearing potential if, in the opinion of the investigator, he/she is biologically capable of having children and is sexually active.

8. Women of childbearing potential must have a negative pregnancy test prior to study enrollment.

9. Subjects who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, daily diary, and other study procedures.

10. Evidence of a personally signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the study.
- Exclusion criteria1. Presence of indeterminate colitis, microscopic colitis, ischemic colitis, infectious colitis, or clinical findings suggestive of Crohn’s disease.

2. Subjects without previous treatment for UC (ie, treatment-naïve).

3. Subjects displaying clinical signs of fulminant colitis or toxic megacolon.

4. Subjects with evidence of colonic adenomas or dysplasia. However, subjects with prior history of adenomatous polyps will be eligible if the polyps have been completely removed and the subjects are free of polyps at baseline.

5. Subjects at risk for colorectal cancer must have a Colonoscopy. Colonoscopy report and pathology report (if biopsies are obtained) must be available in the source document:

• If the subject is >50 years of age, a colonoscopy within 10 years of the screening visit is required to exclude adenomatous polyps. Subjects whose adenomas have been completely excised at baseline will be eligible.

• If the subject has extensive colitis for >8 years or disease limited to left side of colon (ie, distal to splenic flexure) for >10 years, regardless of age, a colonoscopy within 1 year of the screening visit is required to survey for dysplasia. Subjects with dysplasia or cancer identified on biopsies will be excluded.

6. Subjects who have had surgery for UC or in the opinion of the Investigator, are likely to require surgery for UC during the study period.

7. Subjects who have positive stool examinations for enteric pathogens, pathogenic ova or parasites, or Clostridium difficile toxin at screening.

- InterventionsTofacitinib 10 mg twice a day
- Primary outcomeTo investigate the efficacy of twice daily doses of tofacitinib (10 mg bid) to decrease histological inflammation after 8 weeks of treatment in patients with moderate to severely active ulcerative colitis measured by:
Median change in inflammatory infiltrates at week 8 in 2 colon biopsies as assessed by the Robarts Histopathology Index [Mosli, Gut, 2015] and the Geboes index [Geboes, Gut, 2000], by an independent GI pathologist.
- Secondary outcome- Median change in symptoms as measured by the Simple Clinical Colitis Activity Index (SCCAI) at weeks 0, 2, 4 and 8.
- Median change in high sensitivity CRP and fecal calprotectin after treatment with tofacitinib (10 mg bid) for 8 weeks.
- Median change in endoscopic disease severity measured by the Mayo endoscopy score. All endoscopies (screening and week 8) will be videotaped and assessed by 2 independent readers using the Mayo endoscopy score [Schroeder, NEJM, 1987].
- Proportion of patients reaching mucosal healing (Mayo 0/1) after 8 weeks of tofacitinib (10 mg bid).
- Proportion of subjects in endoscopic remission at Week 8. Endoscopic remission is defined by Mayo endoscopic subscore of 0.

- Incidence and severity of adverse events up to 84 days after initiating treatment.
- Proportion of subjects achieving clinical response at Week 8. Clinical response is defined by a decrease from baseline in Mayo score of at least 3 points and at least 30 percent, with an accompanying decrease in the subscore for rectal bleeding of at least 1 point or absolute subscore for rectal bleeding of 0 or 1.

- The proportion of subjects in clinical remission at Week 8. Clinical remission is defined by a total Mayo score of 2 points or lower, with no individual subscore exceeding 1 point.

- The proportion of subjects in symptomatic remission at Week 8. Symptomatic remission is defined by a total Mayo score of 2 points or lower, with no individual subscore exceeding 1 point, and both rectal bleeding and stool frequency subscore of 0.

- The proportion of subjects achieving deep remission at Week 8. Deep remission is defined by a total Mayo score of 2 points or lower, with no individual subscore exceeding 1 point and a zero on both endoscopic and rectal bleeding subscores.

- Brief summaryBiomarker analysis of blood, stool and histological and immunological information of the effects of tofacitinib in ulcerative colitis (UC) is lacking. This is an exploratory study to assess changes in blood, stool and colonic inflammation after 8 weeks of treatment with tofacitinib (XELJANZ) 10 mg BID in patients with moderate to severely active UC. Insight in the histological and immunopathological changes in the colonic mucosa is essential to understand the mode of action of this drug, as patients with residual microscopic inflammation are more likely to relapse. This study will assess the histologic severity, immune cell infiltration, gene expression of inflammatory cytokines and changes in the microbiome in active UC in an open label 8-week study with 2x10 mg tofacitinib per day. Besides severity of inflammation, we will investigate immunological changes in both peripheral blood and mucosa and in stool microbiome after eight weeks of treatment. Analysis of all collected parameters may allow to establish a predictive biomarker profile for response to tofacitinib.
The primary endpoint of this study is to investigate the efficacy of twice daily doses of tofacitinib (10 mg bid) to decrease histological inflammation after 8 weeks of treatment in patients with moderate to severely active ulcerative colitis measured by:
Median change in inflammatory infiltrates at week 8 in 2 colon biopsies as assessed by the Robarts Histopathology Index [Mosli, Gut, 2015] and the Geboes index [Geboes, Gut, 2000], by an independent GI pathologist.
