GEMINI: Entyvio safe in long-term IBD study
SAN DIEGO — Entyvio therapy is safe for the long-term treatment of Crohn’s disease and ulcerative colitis, according to the final results of the GEMINI trial, presented at Digestive Disease Week.
“This is the longest study of continuous vedolizumab (Entyvio, Takeda) exposure to date,” Edward V. Loftus, Jr., MD, of the Mayo Clinic in Rochester, Minnesota, said in his presentation. “This looked at both safety and efficacy of vedolizumab for both UC and Crohn’s disease, and this is the final analysis of that data.”
The GEMINI trial comprised 894 patients with UC and 1,349 with CD who participated in a planned treatment duration of 9 years. All patients received at least one prior conventional therapy.
Researchers observed adverse events in 93% of patients with UC, the most frequent of which was exacerbations (28%). Adverse events were reported in 96% of patients with CD, with the most common being nasopharyngitis (25%).
Investigators observed serious adverse events in 31% of patients with UC and 41% of patients with CD. Exacerbations were the most frequent events in both groups (13% in UC, 17% in CD).
Exacerbations were also the most common reason for discontinuation of the drug, with 9% in UC and 8% in CD. Overall, 15% of patients with UC discontinued due to severe adverse events compared with 17% of patients with CD.
Loftus and colleagues did not observe any new trends for infections, malignancies, infusion-related reactions or hepatic events. There were no new cases of progressive multifocal leukoencephalopathy. Ten patients died during the study (4 in UC, 6 in CD).
Although an expected patient loss to follow-up limited the study’s efficacy analysis, researchers found that patients who continued vedolizumab therapy throughout the entire study were able to maintain clinical response.
“Vedolizumab was safe and well-tolerated for long-term IBD treatment,” Loftus said. “The patients who stayed in the study continued to see favorable clinical outcomes, and these final data are consistent with what is previously known about the safety of vedolizumab.” – by Alex Young
