Infections Incidence Rates Over Time
In the Overall Cohort, IRs of serious infection were generally stable when analysed in 6-month intervals , with the IR at> 30 months no higher than that observed in the first 6 months in the tofacitinib all doses group.
IRs of serious infection by time intervals in the Overall Cohort for tofacitinib all doses, tofacitinib PD 5 mg BID, and tofacitinib PD 10 mg BID groups. PD groups were based on the average total daily dose of tofacitinib during tofacitinib treatment: PD 5 mg BID, an average total daily dose< 15 mg PD 10 mg BID, an average total daily dose15 mg. BID, twice daily CI, confidence interval IR, incidence rate N, total number of patients in the treatment group n, number of patients with events PD, predominant dose UC, ulcerative colitis.
IRs of herpes zoster in the Overall Cohort remained generally stable when analysed in 6-month intervals , with an IR at> 30 months of 2.66 versus 4.46 in the first 6 months in the tofacitinib all doses group.
Of the 28 patients in the Overall Cohort with opportunistic infections, 11 developed opportunistic infections in the first 6 months of tofacitinib treatment. IRs of opportunistic infection were relatively stable over time when analysed in 6-month intervals , with an IR at> 30 months of 0.67 versus 2.25 in the first 6 months in the tofacitinib all doses group.
Study Design And Patients
This was a single-centre retrospective study conducted between November 2005 and December 2020. Patients diagnosed with CD or UC aged> 18 years and managed at Severance Hospital, Yonsei University College of Medicine, Seoul, Republic of Korea, were eligible . Patients had moderately to severely active disease, defined by a Mayo score of 612 for UC and a Crohns disease activity index of 220 or higher for CD. They had also received at least one injection of infliximab, adalimumab, or golimumab as induction treatment, and anti-TNF therapy had been discontinued as the first-line treatment due to a primary non-response, secondary loss of response, occurrence of side effects or malignant tumours, or pregnancy. Those who had not previously used an anti-TNF agent or had been followed-up for< 16 weeks were excluded.

What Are The Potential Benefits Of Taking Jak Inhibitors
In people with UC, an overactive immune response can cause the immune system to attack healthy tissue in the large intestine.
Cytokines play a role in this process. These proteins attach to receptors on the JAK-signal transducer and activator of transcription pathway. This triggers an immune response and can cause the inflammation associated with a number of autoimmune and inflammatory conditions.
JAK inhibitors block cytokines from attaching to receptors in the JAK-STAT pathway. This reduces the amount of inflammation the immune system produces. JAK inhibitors are a treatment option for conditions involving an overactive immune response.
Research has found that JAK inhibitors can help reduce inflammation and relieve symptoms in UC. For some people, they may provide a more effective treatment than biologics.
In a 2012 phase 2 clinical trial, 194 people with moderate to severe UC received Xeljanz or a placebo twice a day for 8 weeks. Clinical remission occurred in:
- 33% of people who received 3-milligram doses of Xeljanz
- 48% of people who received 10-mg doses of Xeljanz
- 41% of people who received 15-mg doses of Xeljanz
- 10% of people who received a placebo
Clinical remission means that the symptoms have resolved completely or nearly completely.
A series of three phase 3 clinical trials also found that Xeljanz was effective in inducing and maintaining remission in UC.
- 16.6% to 18.5% of people who received Xeljanz
- 3.6% to 8.2% of people who received a placebo

How Does The Fda Know Theres An Increased Risk Of Blood Clots
Patients taking Xeljanz for rheumatoid arthritis participated in a clinical trial to see if higher doses would help them. The trials results showed that rheumatoid arthritis patients taking 10 milligrams, twice a day had a higher risk of developing a blood clot in the lungs, a potentially fatal condition known as a pulmonary embolism.
The clinical trial was part of an ongoing post-marketing safety trial run by Pfizer. The results prompted the FDA to add its most serious alert, a black box warning, to Xeljanz. The FDA said the 10 milligram dose is only approved for patients with ulcerative colitis, but warned that the increased risk of blood clots, and of death, applied to them, too.
The FDA quickly followed up by saying Xeljanz should not be provided as a first-line option to treat ulcerative colitis.
The approved use of tofacitinib for ulcerative colitis will be limited to certain patients who are not treated effectively or experience severe side effects with other medicines called tumor necrosis factor blockers.
Quicker Remission With Tofacitinib Vs Vedolizumab In Ulcerative Colitis: Study
When antitumor necrosis factor-alpha treatment fails to achieve remission for patients with ulcerative colitis , tofacitinib appears more effective sooner than vedolizumab , suggests a Dutch registry study.
Data on nearly 150 patients with UC who had already undergone treatment with anti-TNF drugs showed that combined clinical and biochemical remission was about five times more likely with tofacitinib vs vedolizumab within 12 weeks of starting therapy.
However, the differences tailed off over subsequent weeks, such that there was no significant difference in combined remission rates at 52 weeks. There were also no notable differences in safety between the two drugs.
These results may help in guiding clinical decision-making after anti-TNF failure in patients with UC, the authors write.
The research was by Clinical Gastroenterology and Hepatology.

Pfizers Xeljanz won approval from the U.S. Food and Drug Administration as a treatment for patients with moderately to severely active ulcerative colitis , after an inadequate response or intolerance to tumor necrosis factor inhibitor blockers.
The FDA approved extended-release 11 mg and 22 mg tablets as a once-daily treatment from the chronic inflammatory condition. A 10 mg twice-per-day dose of Xeljanz was approved for moderately to severely active ulcerative colitis last year.
Ulcerative colitis is an inflammatory bowel disease that causes long-lasting inflammation and ulcers in the digestive tract. Symptoms typically develop over time but the discomfort can be debilitating and can sometimes lead to life-threatening complications, according to the Mayo Clinic. Some medications can reduce the signs and symptoms of the disease and bring about remission, but there is no cure. Ulcerative colitis affects approximately 907,000 people in the United States.
Michael Corbo, chief development officer of inflammation and immunology at Pfizer Global Product Development, said the symptoms, flares and complications of ulcerative colitis can affect a patients quality of life and be emotionally burdensome. Xeljanz can now be used to remedy those effects of the disease, Corbo said in a statement.
Can I Take Xeljanz With A Biologic
No, you shouldnt take Xeljanz or Xeljanz XR with a biologic drug. Biologic drugs are made in a lab from living cells. Many biologics are designed to suppress the ability of your immune system to fight infections. This is because biologics are generally used to treat autoimmune disorders, which are caused by your immune system mistakenly attacking your own body.
Taking Xeljanz or Xeljanz XR with biologics can suppress your immune system too much. This can increase your risk of very serious infections that your body wont be able to fight off.
Talk with your doctor to learn more about which medications are safe to use with Xeljanz or Xeljanz XR.

Tofacitinib In Special Circumstances
Use in acute severe UC
The rapid onset of action and short half-life have raised the prospect of using tofacitinib in the management of acute severe UC . Data remain limited to a few case reports.30,6064 In three case series, 14 of 15 patients received 3 days high-dose intravenous steroids prior to rescue tofacitinib with a history of anti-TNF failure.30 Eleven patients received standard induction dosing 10 mg BD, whereas the Michigan group used a higher dose of 10 mg three times daily.30,60 Following tofacitinib rescue therapy, 13% required colectomy during that index admission and 20% within 6 months, with no difference in colectomy rates according to tofacitinib dose.30 At the last follow-up, 47% remained in CFCR on maintenance therapy.30 Kotwani et al. reported endoscopic remission in addition to CFCR at last follow-up in 2 of the 4 patients included in their small case series.63 Overall, no major AEs were reported and notably no new thromboembolic events.30,61,64
More recently, a retrospective casecontrol study evaluated the efficacy of tofacitinib induction therapy in hospitalized patients with biologic-experienced ASUC.65 Compared to matched controls, there was a lower 90-day colectomy rate in the 40 patients who received tofacitinib with intravenous corticosteroids . The benefit was only statistically significant at tofacitinib 10 mg three times daily and not at 10 mg BD dosing.65
