ASUC will have a colectomy in 1 year – 25% at 90 days, most during initial hospital stay • High risk of VTE due to inflammation, steroids • Rapid leak of proteins, including biologics • Extended delay of surgery = worse outcomes, death • Best predictors of steroid response - # BMs, CRP at 72 h – Lichtiger, Travis, Ho indices include these • Increasing numbers of ASUC patients have failed at least one biologic, often an aTNF 2 MICHIGAN IBD • JAKs for ASUC

to severe UC • Rapid onset of action • Rapidly cleared (t1/2 = 3.2h)2 – Rapid washout in 18h if need for surgery • Efficacy of 15 mg tid in phase 2 trial • Less susceptible to colon leak & drug loss • No risk of anti-drug antibodies to JAKi • Option for prior aTNF failure • Short trial of JAKi is cheaper than 10 mg/kg IFX – 10 mg tid x 3 days $1,444 vs 700 mg single dose $3,220 • High dose use is short-term, limited risk 5 MICHIGAN IBD • JAKs for ASUC 2Lambal, Clin Pharm. 2016 Sandborn.

& tofacitinib 10 mg tid – Based on 15 mg bid in phase 2, adapted for short half life • Start ASAP upon admission (infectious studies pending) – Taper to 10 bid before discharge with po steroids • Potentially rapid and beneficial • But what are the Risks and Benefits? 6 MICHIGAN IBD • JAKs for ASUC
ASUC, immobility, steroids – Increased by high dose tofacitinib – Mostly in elderly with RA on chronic steroids or malignancy, quite rare in UC trials population without other risk factors (e. g. cancer)3 – Must use daily anticoagulation. Patient must understand the rationale, must not refuse dosing. 8 MICHIGAN IBD • JAKs for ASUC 3Sandborn, WJ. Aliment Pharmacol Ther. 2019; 50: 1068-1076.
patients 50 years of age and older with at least one CV risk factor treated with tofacitinib 10 mg BID had a higher rate of all-cause mortality, including sudden CV death. – Occurred in elderly with RA on methotrexate and chronic steroids, but quite rare in UC trials population3. – Must assess CV risk. http://tools.acc.org • Not a viable strategy with elevated CV risk in > 50 yo – Must stop other small molecules (MTX, Aza, 6-MP) 9 MICHIGAN IBD • JAKs for ASUC 3Sandborn, WJ. Aliment Pharmacol Ther. 2019; 50: 1068-1076.
common infections in UC trials: – Pneumonia – ideally Prevnar and Pneumovax – Cellulitis – inspect skin daily while on steroids plus JAKi – Herpes zoster – Shingrix if available – Urinary tract infection – No catheters – Diverticulitis – Appendicitis 10 MICHIGAN IBD • JAKs for ASUC

patients, 9 doses of tofacitinib over 3 days3 • Several struggle with outpatient authorization • One failed after 9 doses – CRP rises rapidly – to colectomy. 13 MICHIGAN IBD • JAKs for ASUC 3Berinstein, JA, et al. CG&H 2019;17:988–990.
inpatient ASUC therapy • Compare: – ASUC patients who received tofacitinib (10 bid or 10 tid) – Contemporary controls (not as sick as tofa & steroids group) – Historical controls (includes full range of severe to toxic) • Control for: – Prior biologic failure – CRP peak – Albumin nadir – Endoscopic Mayo score – Colonic dilation >5.5 cm at any point during hospitalization 14 MICHIGAN IBD • JAKs for ASUC
Witts’ criteria PLUS started IV steroids • Period 2010-2020 – Matched each tofacitinib case (2016-2020) to 3 controls • Two control groups: – Contemporary control group (match by sex and month of admission) – Historical control group (match by sex and month, and date of admission was prior to 2016) 15 MICHIGAN IBD • JAKs for ASUC
Group: Inclusion Criteria: - Dx of UC - Age >18 - IV CS + T & W - Initiation of tofa inpatient Exclusion Criteria: - Biologic naïve - Dual IFX and Tofa - Post-colectomy Control Group: Inclusion Criteria: - Dx of UC - Age >18 - IV CS + T & W Exclusion Criteria: - Post-colectomy - Part of Tofa group Cases matched to 3 randomly selected controls according sex date of admission
induction to matched controls • Largest study to date • Relatively small size of our tofacitinib group N=40 • Non-randomized retrospective study • Possible signal of longer steroid dependence/taper • May be related to prior authorization issues 27 MICHIGAN IBD • JAKs for ASUC
is associated with a lower risk of colectomy vs. IV steroid SoC in biologic-experienced patients • Unadjusted 2/24 (tid) vs. 4/16 (bid) vs. 23/90 (controls) • Tofacitinib 10 mg BID was not associated with reduced colectomy • Tofacitinib 10 mg TID & SoC IV Steroids may be an effective inpatient induction strategy for biologic-exposed ASUC patients • Inpatient Tofacitinib does not appear to increase complication risk after a small N of 40 • Prospective trials are needed to define the safety profile, optimal dose, frequency, and duration of JAK/CS induction for ASUC 28 MICHIGAN IBD • JAKs for ASUC
potential benefit to accelerated, early dosing with IVCS • Risks are poorly defined, and will require larger N • Short-term induction use and mitigation strategies will likely limit the risks • Patient selection is critical (no cancer, CV risk < 20%) • 2nd generation JAK1-selective agents appear more potent, could be safer • 3rd generation TEC, Tyk2 kinase inhibitors could be even more effective • RCTs of rapid small molecule induction strategies are needed to reduce colectomy rates in ASUC 29 MICHIGAN IBD • JAKs for ASUC
