Researchers at the University of Michigan Health Rogel Cancer Center have identified a mechanism that causes severe gastrointestinal problems with immune-based cancer treatment.

They also found a way to deliver immunotherapy’s cancer-killing impact without the unwelcome side effect.

The findings are published in Science.

“This is a good example of how understanding a mechanism helps you to develop an alternative therapy that’s more beneficial. Once we identified the mechanism causing the colitis, we could then develop ways to overcome this problem and prevent colitis while preserving the anti-tumor effect,” said senior study author Gabriel Nunez, M.D., Paul de Kruif Professor of Pathology at Michigan Medicine.

Many people don’t realize that the trillions of bacteria, viruses, and fungi residing within the gastrointestinal tract — collectively called the gut microbiome — are connected to overall health, and specifically to cancer.

Manipulating the gut microbiome to produce “beneficial” commensal microbes, which protect the host from pathogens and can boost immune responses, among other things, could potentially help patients respond better to cancer drugs called immune checkpoint inhibitors, a type of immunotherapy.

To that end, researchers at the University of Michigan have developed a new dietary fiber formulation that improves the potency of immunotherapies against cancer by modulating the gut microbiome...
