Clinical trial in Seattle aims to transform treatment approaches for pediatric IBD

With pediatric inflammatory bowel disease (IBD) diagnoses on the rise globally, a clinical trial in Seattle aims to transform treatment approaches through deep molecular profiling.

Recruitment has begun for the Seattle STRIDE study, a joint effort by Seattle Children's Research Institute and the Allen Institute for Immunology. The trial aims to enroll 200 volunteers and follow them over three years. It will employ a range of genomic tools to analyze intact tissue samples from routine tests. These single-cell analysis methods will provide a detailed look at how the immune system behaves in patients with IBD and how it responds over time to specific drug treatments.

Deep immune profiling could offer an unprecedented view of the disease, paving the way for new and improved treatments, said Betty Zheng, MD, an assistant professor of pediatrics at Seattle Children's and the study's principal investigator.

IBD is a very complex disease, and we only have a rough understanding of what is happening at a molecular level. By partnering with the Allen Institute, we want to get a detailed view of the disease's molecular mechanisms to find better ways of treating the patients we see in the clinic."

Unraveling molecular mysteries

The exact causes and progression of IBD, a chronic inflammatory condition affecting the digestive tract, have remained elusive, Zheng said. It likely involves some combination of genes, immune dysregulation, and environmental and dietary factors.

In children, IBD is both more aggressive and harder to treat. Around 30% of pediatric IBD patients do not respond to initial treatments. Furthermore, nearly half of the remaining patients will find their treatments becoming ineffective over time. These children face risks like impaired growth, mental health issues, and missed educational and social activities.

A deeper molecular understanding of the disease could enable personalized treatment strategies, moving away from less effective one-size-fits-all approaches, Zheng said.

"Some children find relief with first-line therapies, others require a combination of treatments, and some don't respond to anything and languish in the hospital for months," Zheng said. "This is a big question mark in the clinic."

A deep dive into the molecular workings of the disease could also uncover unknown pathways of inflammation. These pathways could potentially serve as targets for the development of new drugs. "There is a universe of information that is not being seen," said Adam Savage, Ph.D., an Assistant Investigator at the Allen Institute for Immunology.

To explore that universe, Savage and other scientists will deploy a suite of advanced technologies refined at the Allen Institute for Immunology that can identify and pinpoint immune cells and molecules inside tissues collected during routine hospital visits. By analyzing patient samples over time, these tools can offer a window into how the disease progresses and how patients respond to treatment.

Behind the data and the advanced technologies, the ultimate goal remains clear: improving the lives of patients.

"We look at data on computers, or head into the labs, and we can get a little detached," Savage said. "But when we visit and see the patients we're trying to help, it's a powerful reminder of why we come to work-;to have a real impact on patients' lives."
