Care (since 1955) • Definitions & Decision Points • Best Practices post-1955 • Stratifying by Risk of Colectomy • Improving Your Practice with Outcome Data • A Pilot Trial • Where Can We Improve? • Future State
Corticosteroids (IVCS) x 72h • Evaluate with criteria: Oxford/Lindgren/Ho • Most (70-100%) go into remission • Transition to maintenance • Many maintenance choices IVCS Monotherapy, N= 663
Criteria for ASUC in 1955 (no one admitted on steroids) • >= 6 BM/day with visible blood AND 1 or more of • Anemia <= 10.5 g/L of Hgb • Fever > 100F/37.8C • Tachycardia > 90 BPM • ESR > 30 mm/hr • Alternate (lab) definition - classify by FCP • FCP > 782 ~ T&W severe UC • How many outpatients have Calpro >782? • Walking around (or running to toilet) with 1955 ASUC… 2024: My patient does not meet T&W criteria for ASUC - Unless I stop the 60 mg of daily prednisone Kedia, S, et al Dig Dis Sci 2018;63:2747-53
Abby is a 29 y/o F with pancolonic UC, never smoker • Initially on 5-ASA in Jan after prednisone taper, then urgency returned • April started on Aza 2.5 mg/kg, but HA and N/V – stopped after 4 weeks • Started IFX in July b/c flare – worked somewhat for first 3 doses • Admitted with 18 BM/day, blood in ~90%, temp 38.1, very thirsty • C diff negative by toxin, other infections ruled out by PCR • Has not eaten in 2d, because “it goes right through me” • Urgency time ~ 20 seconds • Hgb 7.9, ESR 46, CRP 124 mg/L, Alb 31 → 26 with fluids Risk Factors: CRP, ESR up Alb down Hgb down, fever, Prior Adv Rx
IVCS really still the best first line ASUC therapy? • They are fast & effective in ~ 70%+ • But have lots of side effects, and possibly cause long-term Rx resistance • And we have usually selected AGAINST some fast responders because we have already tried outpatient CS (prednisone) • Other options • Cyclosporine is pretty fast, lots of side effects, not maintenance • IFX is not that fast, leaks a lot, antibodies – kicks can down the road • JAKi are very fast, no leak, no antibodies – relatively few AEs vs CS, can be maintenance or can be a bridge
RCTs? Incentives for Pharma • Recruit the Sickest Patients • Get the Biggest, Fastest Change • Smaller Sample Size • Save Money • Reasonable Conclusion: • Use biologics in the very sick But what do the data say? • The patients who do the best (highest week 52 CS-free remission) are those who enter with LOW (not zero) inflammation • Vedo for UC – FCP <236 mg/g stool • Uste for CD – CRP < 14.6 mg/L APT. 2018 Mar; 47(6): 763–772. JAMA Netw Open. 2019;2(5):e193721. Small molecules Blazing Smoldering
infections, perforation • Do early flexible sigmoidoscopy < 24h • Give lots of fluids early, be slow to feed, be very slow to TPN • Track CRP daily, FCP at discharge • Figure out noninvasive tracking – can’t scope daily, heal too slowly • Mucosal healing and FCP are relatively slow to normalize • Clinical improvement ≠ Out of the woods
urgency (rectal Rx) • Use 3 criteria (Oxford, Lindgren, Ho) and make decision at 72h • Prevent VTE with enoxaparin daily • Give shingrix vaccine if considering JAKi • Measures to reduce PTSD (quiet hours, no CS>4 PM) • Use prognostic criteria to decide who gets First line IVCS • And who needs stronger 1st line therapy Gut 1996; 38: 905-910 EJGH 1998; 10: 831-835 APT 2004; 19: 1079-87
Line Therapy Intravenous steroids (Hydrocortisone or methylprednisolone) Up to 5 mg/kg/day of HC, 1 mg/kg/d of MP Often 100 mg q6h HC, 40q12 of MP JAKi +/- IVCS ? Rescue Therapy Steroids Failing at 72h by 3 criteria Infliximab? Cyclosporine Salvage Therapy Rescue has failed CRP rising Higher risk of infection and death Washout time matters Colectomy is ALWAYS a good option, at any phase Maser, EA CGH. 2008 Oct;6(10):1112.
in 1955? • RCTs in ASUC are hard • Not a lot of patients • ASUC T&W Criteria quite strict for 2024 • Patients anxious, not familiar with trials • Slow to recruit, patients reluctant to enroll • Physicians often reluctant to randomize • 2014: Evolve Therapies through QI approach • When we are confident, run RCTs to prove Rx works Uphill Climb to ASUC RCTs

by testing ‘accelerated’ infliximab • To overcome colonic leak • Rescue after 72h IVCS • Dosed at 10 mg/kg, repeat q72h (up to 3 doses) • Could get some patients out of the hospital • Many returned within 90 days for colectomy • Lots of failure between week 6 and week 14 • None of the patients with 3 doses avoided colectomy • Data were not superior to historical 1 dose IFX rescue • Slightly worse (30.3% vs 24.2%) Govani, SM, Higgins, Dig Dis Sci 2020;65:1800-1805.

Today? • A moving target, as QI and trials are underway • Potent First Line therapy appears to be important • Data on short-term, high-dose JAKi are encouraging • Data on biologics in leaky colons are discouraging • We may be able to bridge from small molecules to biologics • We may be able to drop steroids (early, or entirely) Small molecules Start biologic

STAT3 linker Activates Ubiquitination • A molecule with 3 functional domains: • Binds target protein • Links to proteolysis activator • Protein ubiquinated • Specific degradation of the target protein by the proteasome • One molecule of PROTAC can transiently bind and flag multiple molecules of the target protein • STAT3 is rapidly degraded, gone for 3+ days • STAT3 is regenerated, but not immediately activated by phosphorylation • Temporary ablation of STAT3 that provides time for the immune system to reset • Now testing SD-2301 SD-36-Me Nature Biotechnology; 40,:12–16 (2022) J Med Chem; 62: 11280-11300 (2019) Shaomeng Wang
a Chronic Disease Emergency Department ED South ED West ED East ED Extension 1 ED Extension 2 (Short Stay Unit) "Currently we have 57 patients in the ED awaiting beds. Please prioritize timely discharges." • You aren't going to die in the next 10 minutes • Your history is long and complicated • Your medication names are really long Adrenaline Junkie = ED Doc
Staffed by Nurse Practitioners for flares of chronic diseases • Protocols for CHF, migraine, IBD, other diseases since 2017 • Patient calls with flare symptoms, appointment made for AM • Patient brings in stool, gets blood tests • Rapid FCP, CRP, GI PCR, CBC, Chem, (slower) drug levels • IV fluids, IVCS (possibly JAKi) per protocol • Consult with outpatient GI on next steps / change in maintenance • Option for CTE if needed • In and out within 5 hours
Started for ASUC in June 2024 at UMichigan • ASUC patients who have ‘turned the corner’ per criteria & physician • Typically 48-72h in hospital • Monitoring recovery curve • Go home with daily home nursing care • IV corticosteroids as needed • Daily Lab testing, Vitals • Daily PROs on mobile phone into EMR • Daily Zoom visits with physician • Can get outpt flex sig, X-ray, or return to GI service if a turn for the worse • Early experience: 40 km radius, 4/4 did well, big patient satisfaction
• Rebooting the immune system • Durable immunosuppression, infection, cancer? • To the ADTU instead of the Emergency Department • Will we miss emergencies? • Hospital Care at Home? • Will we be slow to bring patients back to the hospital when needed?
maximize first line Rx? Do we still need steroid tapers?/ Steroids at all? Do all ASUC patients need to be hospitalized? Can patients go home after day 2 with home nursing? Should we delay biologics until smoldering?
• Hypothesis: perioperative BB for noncardiac surgery • Lots of rapid publications • Led guidelines group, implemented BB in Europe • Other sites data ~ 27% increased mortality • Estimated 800K additional deaths in Europe • Many incentives and paths to research misconduct • External validation is critical • Believe in science, not your beloved hypothesis
