FDA
Tremfya approved for Crohn disease
FDA approved Tremfya (guselkumab) for the treatment of adults with moderately to severely active Crohn disease (CD).
Efficacy
Approval of the new indication was based on data from three phase 3 trials involving >1,300 patients with moderately to severely active CD who failed or were intolerant to conventional therapy (i.e. corticosteroids or immunomodulators) or biologics: GALAXI 2 and GALAXI 3 (NCT03466411) and GRAVITI (NCT05197049). Results of these studies demonstrated robust efficacy of SC or IV Tremfya in achieving clinical and endoscopic endpoints, according to a manufacturer press release.
Safety
The most common adverse reactions reported with guselkumab in patients with CD were respiratory tract infections, abdominal pain, injection site reactions, headache, fatigue, arthralgia, diarrhea, and gastroenteritis.
