VIENNA — , according to interim results of a pivotal phase 3 trial.
Treatment with cendakimab also improved key endoscopic and histologic features, even in patients who had an inadequate response or intolerance to steroids, reported Alain Schoepfer, MD, gastroenterologist from Centre Hospitalier Universitaire Vaudois and University of Lausanne, in Switzerland.
The drug was generally safe and well tolerated up to 24 weeks of treatment, added Schoepfer, who presented the results during a presentation at the United European Gastroenterology (UEG) Week 2024.
Targeting IL-13 Shows ‘Surprisingly Good Results’
EoE is a chronic, progressive, immune-mediated, inflammatory disease that is mainly driven by the cytokine, IL-13.
In a prior phase 2 study, cendakimab, which selectively binds to IL-13 and blocks its interaction with both the IL-13Ra1 and the IL-13Ra2 receptors, was shown to improve symptoms and endoscopic features of EoE.
For the current phase 3 trial, participants were required to have a peak eosinophil count (PEC) of ≥ 15 eosinophils (eos)/high power field (hpf) and 4 or more days of dysphagia over the 2 weeks prior to the start of the study. In addition, they had to have shown a complete lack of response to proton pump inhibitor (PPI) treatment for 8 weeks or more.
A total of 430 patients were randomized 1:1:1 to subcutaneous cendakimab (360 mg) once weekly for 48 weeks; subcutaneous cendakimab (360 mg) once weekly for 24 weeks, then once every 2 weeks for a further 24 weeks; or subcutaneous placebo once weekly for 48 weeks.
Patient characteristics were similar across randomization groups. The majority of participants were men, with a mean age of 35 years (range, 12-75 years); adolescents comprised 6%-11% of the total. The disease duration was around 5-6 years for all participants, of which 45% were on a stable PPI dosage and around 65% had steroid intolerance or an inadequate response. The endoscopic reference score was around 10 across all groups. The mean PEC was around 160 eos/hpf in the cendakimab arms vs 200 eos/hpf in the placebo arm.
Schoepfer reported results for the coprimary endpoints — the mean change from baseline in dysphagia days and the proportion of patients with eosinophil histologic response (PEC ≤ 6 eos/hpf) — at week 24. At this point, a total of 286 patients had received treatment with 360 mg of cendakimab once weekly, and 143 had received placebo.
The change in dysphagia days was −6.1 in patients on cendakimab once weekly vs −4.2 in patients on placebo (P = .0005). The proportion of patients with eosinophil histologic response was 28.6% in the treatment arm vs 2.2% in the placebo arm.
The results were similar for patients who were classified as having had a steroid inadequate response. The change in dysphagia days was −6.3 in the cendakimab group vs −4.7 in the placebo group (P = .0156). The eosinophil histologic response was 29.5% in the treatment group vs 2.1% in the placebo group (P < .0001).
Endoscopic response, a key secondary endpoint, showed a change from baseline to week 24 in the endoscopic features of EoE. The total endoscopic reference scores were −5.2 for patients on cendakimab once weekly and −1.2 for patients on placebo (P < .0001).
The safety profile of cendakimab was “unspectacular,” Schoepfer said, with adverse events related to the study drug occurring in 30% of patients in the treatment arm vs 18.9% of those in the placebo arm. He noted that as the trial was conducted during the COVID pandemic, there were some infections.
Serious adverse events, which were assessed by investigators to not be related to the study drug, occurred in 1.8% and 2.8% of patients on cendakimab and placebo, respectively. Drug discontinuation occurred in 1.4% in the cendakimab group and 0.7% in the placebo group. There were no deaths.
“We really need drugs for this disease, given that there are very few alternatives to steroids and PPIs,” Co-moderator Ram Dickman, MD, Division of Gastroenterology, Rabin Medical Center, Petah Tikva, Israel, said in an interview.
Right now, we have dupilumab, which targets two receptors: IL-4 and IL-13. But targeting IL-13 by itself “is showing surprisingly good results,” so cendakimab is a good candidate to be in “the first line of biologic treatments,” Dickman said.
“It’s safe and works rapidly,” he added. “Given this is a phase 3 study, I believe we’ll see it on the market.”
Schoepfer has served as a consultant for Regeneron/Sanofi, Adare/Ellodi, AbbVie, AstraZeneca, Celgene/Receptos/Bristol Myers Squibb, Dr. Falk Pharma, Gossamer Bio, GSK, Janssen, MSD, Pfizer, Regeneron/Sanofi, Takeda, and Vifor; received grant/research support from Adare/Ellodi, Celgene/Receptos/Bristol Myers Squibb, GSK, and Regeneron/Sanofi. Dickman has declared no relevant disclosures.
