Crackdown on unproven stem cell therapies long overdue, Ottawa scientist says

An Ottawa scientist says it's about timeHealth Canada crackeddown on clinics offering unproven and potentially unsafe treatments that inject patients with their own cells,and he'd like to see the provinces follow suit.

"They're not supported by any evidence whatsoever, and their claims are mostly wrong," saidMichael Rudnicki, director of regenerative medicine at The Ottawa Hospital.

"There's absolutely no regenerative effect that'soccurring."

Health Canada said it's ordering three dozen of these clinics across Canada to stop offering the services immediately. They include three businesses in Ottawa and one in Kingston, Ont.

The federal agencyissued compliance letters to Inovo Medical, Dr. David Simonand Oxygen Medi Spa in Ottawa,KOPI Stem Cell in Kingston, as well as 32other clinics across the country.

The clinics offered patients a variety of stem cell and platelet-rich plasma treatments for a variety of healthissuesincluding hair loss, arthritis, heart problems, eye issues and multiple sclerosis. Patients are typically charged thousands of dollars for the treatments.

"Generally, products using stem cells to cure or treat disease remain at the investigational stage of development," Health Canada said in an email.

"This means that Health Canada has not yet seen enough evidence that they are safe and effective."

A growing problem

Rudnickisaid many of these clinics claim injecting patients with their own cells promotes healing, but these unproven "stem cells" therapies can actually be harmful.

In the case of the platelet-rich plasma treatments, the clinics use a concentrated amount of platelets from a patient's blood and inject them back into the person to promote healing.

But that can pose riskssuch as cross-contamination if equipment isn't cleaned properly, or potentially dangerous immune reactions.

"It's a growing problem, I think, over the last 10 years," Rudnicki told CBC Radio's All In A Day.

Stem cell research holds a lot ofpromise and there's beenhuge scientific advances,Rudnickisaid,but these clinics are using this excitement as a "marketing ploy."

"What these people are doing is essentially illegal," he said.

"Stem cells are classified as drugs by Health Canada and you cannot just give people drugs that are not approved by Health Canada."

Time for provinces to act

Rudnickisaid he welcomes the federal government's decision to crack down, but he would also like the same initiative to be taken by the province.

"Health Canada has really stepped up its game and that'sa great start, but we also need the provincial authorities to become involved," he said.

On Tuesday afternoon, CBC contacted the Ottawa and Kingston clinics that were issued compliance letters, but they haven'tresponded.
