'Blazing the trail': University of Calgary research could lead to cures for autoimmune diseases

Researchers at the University of Calgary say their work in the field of "nanomedicine"could lead to cures for Type 1 diabetes, multiple sclerosis and many more diseases.

Dr. Pere Santamaria said the process involves "nanoparticles" thousands of times smaller than a typicalhuman cell that could be used to stop the body from attacking itself.

That, he said, could potentially lead to cures for autoimmunedisorders.

"There are no drugs that can do that today,"said Santamaria, aprofessor ofimmunology at the University of Calgary.

"Other drugs that are being used to treat chronic inflammatory disorders impair the ability of the immune system to do its job, so there are secondary effects and longterm complications our drugs don't do that."

Pharmaceutical company Novartis has partnered with Santamaria's own company, Parvus Therapeutics, to work on developing the nanomedicines and take the drugs to market.

From treatment to cure

Now with support and funding, Santamariasaid the new drug"has the potential to revolutionizemedicine" if the drugs pass clinical testing.

Santamariasaid autoimmune disordersarecaused by white blood cells attacking the tissues in a person'sown body.

Type 1 diabetesis treatable with insulin, but there is no cure. It's the same for many other diseases.

"Our drugs aim to resolve the inflammation of the tissue, the attack of the tissue, and resolve that process altogether," Santamaria said.

He said the nanoparticles could halt disorders without impairing the rest of the immune system.

"So we can reset the immune system to its steady state that means the healthy state without impairing the ability of our immune system to protect us against infections and cancer,"Santamariasaid.

Long time coming

Santamaria said the nanoparticleswere discovered during an experiment years ago, and the initialtestresults"made nosensewhatsoever." Since that day, the nanomedicines havebeen in development and he credits the progress to curiosity.

"We almost shoved them under the rug," Santamaria said."We didn't do that. Fortunately, we were pursued wth curiosity of researching."

Santamaria said the process of taking a discovery from the research laboratory to the marketplace is enormously complex and the drug has yet to go through preclinical trials.

Because nanomedicine is such a new field of research, there is no firm timeline on when the medicinescould be available if they pass human trials.

"Our nanomedicineis a new class of drug ... so we're basically blazing the trail," Santamaria said.

"We hope that we can carry that torch and be an example for all the investigators that might follow suit, that may run into discoveries such as the ones that we've made and hopefully they can follow in our footsteps."
