Advanced Drugs Should Be Used First In Crohn's Disease, New Guidelines Suggest

Key TakeawaysNew guidelines for Crohn’s disease recommend going to advanced drugs immediatelyThe guidelines recommend using these drugs first rather than using a step-up approach trying less-effective meds firstThe update is meant to keep up with the current research.THURSDAY, Nov. 20, 2025 (HealthDay News) — New guidelines recommend doctors tackle Crohn’s disease head-on, calling for the use of cutting-edge drugs as early as possible to quell the autoimmune GI disorder as quickly as possible.The updated American Gastroenterological Association guidelines reject a “step-up” approach in which people get more advanced drugs only after they’ve tried cheaper, less effective medications like steroids or immunomodulating drugs like thiopurines.Instead, doctors should go straight to monoclonal antibody drugs that target different factors that promote Crohn’s disease, according to 2025 guidelines published in the journal Gastroenterology.“The science in Crohn’s disease is moving quickly, and our goal was to translate that evidence into clear, meaningful recommendations for front-line clinicians,” guideline author Dr. Siddharth Singh, a gastroenterologist with the Mayo Clinic in Phoenix, Arizona, said in a news release.Insurance companies encourage the step-up approach as a means of limiting costs, the AGA says. Patients are required to try less effective but cheaper drugs before insurers will agree to cover more advanced medications.“We didn’t write this guideline to follow insurance rules,” Singh said. “Insurance coverage should follow the evidence.”Crohn’s disease occurs when the immune system causes damaging inflammation in a person’s digestive tract, according to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).The most common symptoms are diarrhea, abdominal pain and weight loss, but if left untreated Crohn’s disease can lead to anemia, bone loss, malnutrition and colon cancer, the NIDDK says.In its new guideline, the AGA recommends infliximab, adalimumab, ustekinumab, risankizumab, mirikizumab, guselkumab or upadacitinib as first-line treatments for moderate-to-severe Crohn’s disease.Most of these drugs are monoclonal antibody therapies that target different biological factors that drive the inflammation associated with Crohn’s, experts said.The guidelines also recommmend a small-molecule drug called upadacitinib, which helps by inhibiting an enzyme that promotes inflammation. Other suggested drugs include certolizumab pegol and vedolizumab.The guideline specifically suggests against using the class of immune-modulating drugs known as thiopurines to make Crohn’s symptoms go away.However, thiopurines can be used to keep Crohn’s at bay in patients who’ve gone into remission using steroid drugs, the guideline says.“These recommendations are about helping patients and providers make informed choices,” Singh said. “Our goal is to empower shared decision-making and ensure these evidence-based options are accessible and covered by insurance.”“Patients should recognize that there are now multiple treatment options available to them, regardless of where they are in their treatment journey,” Dr. Frank Scott, chair of the guideline panel, said in a news release. “These guidelines highlight those options — and they call for payors to align their formularies with evidence-based medicine.”More informationThe National Institutes of Health has more about treatment options for Crohn’s disease.SOURCES: American Gastroenterological Association, news release, Nov. 20, 2025; Gastroenterology, December 2025.What This Means For YouChron’s disease patients should talk with their doctor about the new guidelines and how they might alter treatment options..Sign up for our weekly HealthDay newsletter
