Frequently asked questions about OD-07656

What is OD-07656 used for?

OD-07656 is an investigational small molecule being developed for inflammatory bowel diseases, including ulcerative colitis (UC). It is being studied in a Phase 2 trial for moderately to severely active ulcerative colitis, and a Phase 1 trial also included conditions such as Crohn disease, Blau syndrome, and spondyloarthritis.

What does OD-07656 target?

OD-07656 targets RIPK2, a protein kinase involved in innate immune signaling. By inhibiting RIPK2, the drug is designed to modulate inflammatory pathways relevant to gastrointestinal diseases like ulcerative colitis.

Who is developing OD-07656?

OD-07656 is being developed by Odyssey Therapeutics, Inc., a biopharmaceutical company. The company is conducting clinical trials of the drug in patients with ulcerative colitis and related inflammatory conditions.

What phase is OD-07656 in?

OD-07656 is in Phase 2 clinical development for moderately to severely active ulcerative colitis. A Phase 1 study in healthy participants has been completed, and the drug remains investigational and not yet approved by regulatory authorities.

What clinical trials is OD-07656 in?

OD-07656 has two clinical trials. NCT06206811 is a completed Phase 1 study in healthy adult participants in Australia. NCT06850727 is a recruiting Phase 2 trial evaluating safety and efficacy of OD-07656 and subsequent vedolizumab therapy in moderately to severely active ulcerative colitis across multiple countries.

Is OD-07656 the same as any other drug?

OD-07656 is the sole name provided for this investigational drug. No alternative names or brand names have been associated with it in the available clinical trial information.
