Risankizumab has early and lasting benefits in Crohn’s disease


 

AT ACG 2021

FORTIFY study

In FORTIFY, the maintenance trial that followed, the researchers rerandomized those patients who had responded to risankizumab into three groups. Two groups received subcutaneous injections of risankizumab, with 179 patients getting 360 mg and another 179 patients getting 180 mg. The placebo group included the remaining 184 patients.

At week 52, 40.9% of patients in the placebo group were in clinical remission, compared with 52.2% in the 360-mg group and 55.4% in the 180-mg group, which was statistically significant (P = .005 for 360 mg, and P = .003 for 180 mg.)

“It showed us that [risankizumab] could achieve deep remission, which means patients achieving remission endoscopically in combination with clinical remission,” the presenter, Marla Dubinsky, MD, professor of pediatrics and medicine in the division of pediatric gastroenterology at Icahn School of Medicine at Mount Sinai in New York, said in an interview.

Over the 52 weeks, deep remission and endoscopic remission rates increased in the 360-mg group, held steady in the 180-mg group, and decreased in the placebo group. Mean fecal calprotectin and C-reactive protein levels decreased in the risankizumab groups and increased in the placebo group.

There were more total treatment-emergent adverse events per 100 patient-years in the placebo group (339.7) than in the 360-mg group (269.3) or the 180-mg group (283.5). The same difference between groups was true of severe treatment-emergent adverse events. Serious events and events leading to discontinuation were similar in the three groups.
