New small-molecule immune medicines to help treat inflammatory bowel disease

Optimization of small molecule immunomodulators as combination therapy for IBD

NIH-funded research Weill Medical Coll of Cornell Univ · NIH-11303324

Looking at whether new pill-form immune drugs that target two immune signals (CD28 and ICOS) can be combined to help people with inflammatory bowel disease who do not respond well to current therapies.

What this research studies

Researchers will use a platform called SMAPs to design small molecules that bind immune receptors involved in IBD, aiming to mimic the effects of protein drugs without the same immune reactions. They will optimize these compounds for potency, selectivity, and manageable drug levels in the body. The team will test candidates in lab assays and animal models to check how well they block CD28 and ICOS signaling and whether combinations work better than single agents. Successful leads would move toward safety testing and eventual clinical trials in people with IBD.

Who could benefit from this research

Good fit: People with moderate-to-severe Crohn's disease or ulcerative colitis who have had inadequate or lost responses to existing biologic or small-molecule treatments would be the likely candidates for eventual trials.

Not a fit: People whose IBD is mild and well controlled on current therapy, or whose disease is driven primarily by non-immune factors, are less likely to benefit from these immune-targeting compounds.

Why it matters

Potential benefit: Could produce oral drugs that work alongside or instead of current biologics to control IBD more reliably with fewer immune reactions.

How similar studies have performed: Biologic antibodies that block CD28 and ICOS pathways have shown promise, but developing small-molecule versions is a new and largely untested approach in humans.
