S Friedberg et al. Clin Gastroenterol Hepatol 2023; 21: 1913-1923. Open Access! Upadacitinib Is Effective and Safe in Both Ulcerative Colitis and Crohn’s Disease: Prospective Real-World Experience

Methods: “We performed a prospective analysis of clinical outcomes on upadacitinib in patients with UC and CD using predetermined intervals at weeks 0, 2, 4, and 8 as part of a formalized treatment protocol.” 84 met inclusion criteria (44 UC patients, 40 CD patients) -though complete data was available for only a fraction of these. All of the patients had received prior anti-TNF therapy and 89% had received 2 or more advanced therapies.

Key findings:

Ulcerative colitis: At 4 and 8 weeks of treatment, 19 of 25 (76.0%) and 23 of 27 (85.2%) achieved clinical response and 18 of 26 (69.2%) and 22 of 27 (81.5%) achieved clinical remission, respectively. Of those who previously were tofacitinib-exposed, 7 of 9 (77.8%) achieved clinical remission by 8 weeks.
Crohn’s disease: In CD, 13 of 17 (76.5.%) achieved clinical response and 12 of 17 (70.6%) achieved clinical remission by 8 weeks. Of those with increased fecal calprotectin and C-reactive protein levels, 62% and 64% normalized by week 8, respectively.
Results were seen as early as week 2 in both UC and CD, with clinical remission rates of 36% and 56.3.%,
Acne was the most commonly reported adverse event, occurring in 24 of 105 patients (22.9%) (Table 4). Six patients stopped upadacitinib due to adverse effects.

My take: “In this large real-world experience in medically resistant patients with UC or CD, we report that upadacitinib is rapidly effective and safe, including in those who had prior tofacitinib exposure.” In pediatrics, the effectiveness of this upadacitinib is a logical target for ImproveCareNow. More pediatric data will be needed to garner FDA approval.

Rapid Clinical Remission With Upadacitinib in a Pediatric Patient With Refractory Crohn’s Disease A pediatric patient with Crohn’s disease refractory to anti-tumor necrosis factor therapy, vedolizumab, ustekinumab, and 6-mercaptopurine achieved rapid clinical remission with upadacitinib.

A Bousvaros, BAR Schmidt, M Kurtz. Gastroenterology & Hepatology 2023; 19: 401-403. Open Access! “Treatment of Genital Crohn’s Disease with Upadacitinib in a Male Child: A Case Report”. This report describes the rapid response to upadacitinib in a 12 yo with refractory Crohn’s ileocolitis (x 5 yrs) with associated “granulomatous lymphangitis” affecting the penis and scrotum. It notes that “anti-TNF therapy was described as the most effective treatment, with either improvement or resolution of scrotal swelling in most patients. However, intermittent penile swelling persisted in a subset of the patients.¹⁸“…”Although data on the use of JAK inhibitors to treat pediatric IBD are limited, the fact that these are small molecules with wide systemic effects suggests that JAK inhibitors may be useful in the treatment of extraintestinal manifestations of IBD….[and] that JAK inhibitors such as upadacitinib may play an important role in the treatment of such refractory patients.”
