Clinical trial will test promising cell therapy for septic shock


January 19, 2023

Dr. Lauralyn McIntyre“Researchers around the world have spent decades trying to find new therapies for septic shock, but so far nothing has improved survival, nor the quality of life for survivors of this devastating illness. We urgently need new treatments for septic shock, and to test them in randomized controlled trials like this one.” -Dr. Lauralyn McIntyreDr. Lauralyn McIntyre was awarded $1.6 million from the Canadian Institutes of Health Research Clinical Trials Fund to conduct a Phase II clinical trial of mesenchymal stem cells (MSCs) in patients with septic shock.

This deadly condition occurs when an infection spreads through the body and over-activates the immune system, causing the heart and other organs to fail. MSCs have been shown to dampen the damaging part of the immune response while bolstering the more beneficial parts.

Dr. McIntyre and her team previously conducted the first clinical trial in the world of MSC therapy for septic shock.

This new funding will allow them to complete a larger randomized controlled clinical trial in 10 centres across Canada to see whether the cells can reduce patients’ need for organ support in the ICU. The team had previously secured $1 million in funding from the Stem Cell Network to recruit 122 participants, and this new funding will allow them to recruit 174 more. They plan to begin recruitment in the spring. 

“Researchers around the world have spent decades trying to find new therapies for septic shock, but so far nothing has improved survival, nor the quality of life for survivors of this devastating illness,” said Dr. McIntyre, senior scientist and critical care physician at The Ottawa Hospital and associate professor at the University of Ottawa. “We urgently need new treatments for septic shock, and to test them in randomized controlled trials like this one.”

Sepsis is recognized as a global health priority, with an estimated 48.9 million cases of sepsis and 11 million sepsis-related deaths worldwide annually.

Researchers at The Ottawa Hospital are also playing a lead role in several other projects funded through the Clinical Trials Fund, including the Accelerating Clinical Trials (ACT) Consortium, and the Canadian-Led Immunotherapies in Cancer (CLIC) clinical trial.
