Icotrokinra Hits Key Clinical Response Goal in Ulcerative Colitis Study, Shows Transformative Potential

Johnson & Johnson has unveiled promising results from its Phase 2b ANTHEM-UC study, showcasing the potential of icotrokinra (JNJ-2113), a pioneering investigational oral peptide targeting the IL-23 receptor, in the treatment of ulcerative colitis (UC). This innovative therapy has demonstrated significant efficacy, meeting the primary endpoint of clinical response in all dosage groups, and displaying notable differences in key secondary endpoints such as clinical remission, symptomatic remission, and endoscopic improvement when compared to placebo at Week 12.

The ANTHEM-UC study, involving 252 participants, evaluated three different doses of the once-daily oral icotrokinra. All dosage groups successfully achieved the primary endpoint of clinical response by Week 12. Among patients who received the highest dose of icotrokinra, 63.5% showed a clinical response compared to just 27% in the placebo group, a statistically significant difference (p<0.001). Furthermore, at the same time point, 30.2% of those on the highest dose of icotrokinra achieved clinical remission, as opposed to 11.1% of placebo recipients (p<0.001). These remission and response rates continued to improve through Week 28.

The safety profile of icotrokinra was favorable, with a similar incidence of adverse events reported across both icotrokinra and placebo groups. This indicates good tolerability for the drug, which could revolutionize treatment for ulcerative colitis patients by combining therapeutic efficacy with the convenience of a once-daily oral regimen.

Dr. Esi Lamousé-Smith, Vice President and Gastroenterology Disease Area Lead at Johnson & Johnson’s Immunology division, emphasized the transformative potential of icotrokinra, noting its unique combination of therapeutic benefit, tolerability, and convenience. She expressed excitement about the groundbreaking implications for treating immune-mediated diseases, highlighting Johnson & Johnson's long-standing commitment to innovation in inflammatory bowel disease and their expertise in the IL-23 pathway.

The comprehensive results from the ANTHEM-UC study are slated for presentation at upcoming medical congresses, further underscoring the promising future of icotrokinra in clinical applications.

Ulcerative colitis is a chronic condition affecting the colon, characterized by inflammation and the formation of ulcers that produce pus and mucus due to an overactive immune response. Patients experience symptoms like urgent bowel movements, rectal bleeding, diarrhea, abdominal pain, and fatigue. The development of icotrokinra represents a significant advancement in addressing these symptoms by targeting the IL-23 receptor, a critical component in the inflammatory pathway associated with UC and other autoimmune conditions.

Icotrokinra's development is the result of a collaboration between Johnson & Johnson and Protagonist Therapeutics, Inc., initiated in 2017. This partnership aimed to discover next-generation compounds for immune-mediated diseases, leading to the creation of icotrokinra. Johnson & Johnson holds exclusive rights to further develop and commercialize icotrokinra for a broad range of indications beyond Phase 2 clinical trials.

In addition to ulcerative colitis, icotrokinra is undergoing evaluation in the Phase 3 ICONIC clinical program for moderate-to-severe plaque psoriasis and active psoriatic arthritis. This investigational drug's ability to selectively inhibit IL-23 signaling offers potential therapeutic benefits across various IL-23-mediated diseases, positioning it as a versatile candidate in the biopharmaceutical landscape.

Johnson & Johnson's commitment to healthcare innovation continues to drive progress in treating complex diseases, striving to offer less invasive, more personalized, and smarter treatment solutions. Through their expertise in Innovative Medicine and MedTech, the company is poised to deliver groundbreaking healthcare advancements that profoundly impact human health.
