Guselkumab is the first and only interleukin-23 (IL-23) inhibitor available as both SC and intravenous (IV) induction options for the treatment of UC and Crohn’s disease (CD), the company noted in a news release.
The approval of SC guselkumab induction in UC was based on results from the phase 3 ASTRO trial, which randomly allocated 418 patients with moderately to severely active UC to receive either induction with 400 mg SC guselkumab at weeks 0, 4, and 8 or placebo.
Following induction, the treatment group either received a maintenance dose of 200 mg SC guselkumab at week 12 and then every 4 weeks or 100 mg every 8 weeks (starting at 16 weeks).
All patients had had an inadequate response or intolerance to conventional therapy.
All primary and secondary endpoints demonstrated statistically significant and clinically meaningful improvements with SC guselkumab compared to placebo across all clinical and endoscopic measures, the company said.
At 12 weeks, a significantly greater proportion of patients treated with 400 mg SC guselkumab every 4 weeks achieved clinical remission (26% vs 7% with placebo; P < .001) and endoscopic improvement (36% vs 12%; P < .001).
The results were consistent with the FDA-approved 200 mg IV induction regimen, which previously achieved clinical remission (23% vs 8% with placebo; P < .001) and endoscopic improvement (27% vs 11%; P < .001).
The efficacy of SC and IV induction was comparable across subgroups with severe or refractory disease and both routes demonstrated a similar time to onset of efficacy.
SC guselkumab induction followed by SC guselkumab maintenance therapy also demonstrated statistically significant and clinically meaningful improvements in clinical remission and endoscopic improvement compared to placebo.
“Historically, IL-23 inhibitors have required IV infusions at the start of therapy, which can create barriers to starting treatment or be burdensome for some patients and clinicians,” study investigator David T. Rubin, MD, AGAF, director of the Inflammatory Bowel Disease Center at University of Chicago Medicine, said in the news release.
“UC patients and providers now have the choice of starting Tremfya with a self-administered subcutaneous injection, with the same efficacy and safety that were established with IV induction in the prior clinical trials and subsequently seen in our real-world practice,” Rubin said.
