Johnson & Johnson’s experimental therapy for inflammatory bowel disease (IBD), JNJ-4804, failed to demonstrate a statistically meaningful improvement in patients during Phase 2b clinical trials. However, the company has announced plans to advance the drug into late-stage testing, targeting a specific subgroup of IBD patients.

On Tuesday, trial investigators presented the results of the DUET study, which evaluated the efficacy of combining Tremfya and Simponi to prevent the immune system from attacking healthy tissues in the digestive tract. The study followed a 2022 clinical trial that showed significant benefits, nearly doubling disease remission rates and inspiring other companies to explore combination therapies for IBD.

Johnson & Johnson tested JNJ-4804 in two Phase 2b trials, covering both major forms of IBD: ulcerative colitis and Crohn’s disease. While the combination therapy outperformed the individual drugs in both trials, it did not meet the primary endpoint of achieving clinical remission.
