Toronto firefighter back on the job after new drug slows ‘incurable brain cancer’

In December 2020, Steven Stefanidis, a 36-year-old firefighter from Toronto, was responding to a aesculapian telephone erstwhile helium blacked retired and had a seizure.

After being assessed by archetypal responders, helium was taken to the hospital, wherever an MRI revealed a tumour. It was diagnosed arsenic a Grade 2 IDH-mutant glioma, an incurable signifier of encephalon cancer.

It came arsenic a implicit shock, Stefanidis recounted to Global News.

“Here I was successful my aboriginal 30s, surviving my champion beingness with a imagination occupation erstwhile I abruptly had a seizure. I can’t picture what it was similar to beryllium told that I had an incurable encephalon cancer,” helium said.

“At archetypal I was successful daze and I wasn’t digesting the accusation due to the fact that it’s heavy. But overall, the neurosurgeon that I met was precise relaxed and assured and I trusted him and helium enactment maine successful a bully situation. I didn’t freak retired oregon anything. I knew I was successful bully hands astatine the moment.”

He aboriginal underwent country to alleviate his symptoms, which took spot 1 week aft his diagnosis.

Stefanidis is 1 of the thousands of Canadians diagnosed with encephalon and spinal cord crab each year, according to the Canadian Cancer Society. The benignant helium has, gliomas, is the second-most communal crab among Canadians nether 40 and the second-leading origin of cancer-related deaths successful this property group.

And IDH-mutant glioma usually arises successful radical successful their 30s and 40s, erstwhile they are successful the premier of their lives — moving and raising families, explained Dr. Mary Jane Lim-Fat, neurologist and neuro-oncologist astatine Sunnybrook Health Sciences Centre.

“There is nary existent cure for diffuse gliomas successful adults,” Lim-Fat told Global News. “So our champion treatments, which up until present person consisted of radiation and chemotherapy, lone hold the clip until which the tumour grows back. It’s been precise challenging to find amended treatments for our patients.”

But determination is hope. A caller oral medicine called Voranigo has been shown to people encephalon tumours, and successful Phase 3 objective trials, to “significantly” dilatory their growth. Stefanidis participated successful these objective trials astatine Sunnybrook Health Sciences Centre successful Toronto, and helium said the attraction has been effectual for his cancer.

“Since receiving the attraction during the objective trials… there’s nary broadside effects from the medication, and connected the affirmative side, we’ve noticed stabilization and immoderate shrinkage successful the remaining [tumour],” helium said.

And present it has officially been approved successful Canada.

On Tuesday, Health Canada announced the support of Voranigo, the archetypal targeted therapy for treating Grade 2 isocitrate dehydrogenase (IDH)-mutant glioma successful adults and pediatric patients aged 12 and older, pursuing surgery. It is Canada’s archetypal oral targeted attraction for encephalon cancer.

Voranigo was studied successful a large-scale, randomized, placebo-controlled objective proceedings with patients from astir the world, including Canada, from January 2020 done February 2022.

The results of the Phase 3 objective trials were published successful June 2023 successful the New England Journal of Medicine, and amusement promising results, Lim-Fat said.

“This caller cause fundamentally is simply a encephalon penetrant oral cause that patients tin instrumentality by rima that alters the relation of that mutant protein. So successful doing that, it slows down the maturation of the tumour, stabilizes it successful immoderate instances, and adjacent decreases the maturation oregon shrinks the tumours successful immoderate cases,” she said.

So what precisely does this mean?

Gliomas are hard to dainty and often advancement to much assertive forms of encephalon cancer, partially owed to the blood-brain barrier. This protective furniture shields the encephalon from harm but besides makes it challenging for therapies to penetrate and efficaciously people tumours, Lim-Fat explained.

Due to the blood-brain barrier, the existent attraction for gilomas involves a operation of surgery, followed by radiation and chemotherapy. While these treatments tin temporarily halt the tumour’s growth, Lim-Fat noted that it yet returns.

But Voranigo is specifically designed to transverse the blood-brain obstruction and scope the encephalon to people mutated enzymes that are causing the cancer.

Phase 3 objective proceedings results amusement that the cause much than doubled the clip earlier the tumour grew backmost successful patients. It besides delayed the request for interventions similar chemotherapy and radiation, which travel with terrible broadside effects.

“The median progression-free endurance for patients who were connected placebo — truthful did not person thing — was astir astir 11.1 months. But erstwhile they looked astatine the radical that got [Voranigo], that progression-free survival, that hold was much than treble that time, it was 27.7 months,” Lim-Fat said.

“These results successful and of themselves are precise encouraging and showed that this cause was really rather bully astatine delaying that progression successful these patients.”

Now that Voranigo is approved successful Canada, Stefanidis said helium hopes the medicine tin assistance others who are successful the aforesaid situation.

After taking clip disconnected work, helium is present backmost connected the occupation arsenic a firefighter and has adjacent started traveling, exercising and hiking again.

“I consciousness similar a regular, normal, steadfast adult. I’m dilatory backmost to my regular day-to-day routine. I’m backmost to enactment now, afloat backmost connected the occurrence trucks responding. And it feels large to beryllium backmost connected with the aforesaid crew,” helium said.

“I conscionable precocious had my archetypal abrogation successful July of this year. And it felt astonishing conscionable to get retired there. And that’s different happening astir this medication. It’s not thing wherever I had to enactment wrong my country due to the fact that I could lone get the attraction there. I’m capable to transportation this with maine wherever I spell and usage it arsenic similar a mobile treatment,” helium added.

Stefanidis said helium takes it erstwhile each morning, akin to a multivitamin, and keeps way of it successful his diary for dosage and time.

Lim-Fat expressed that the oncology assemblage is genuinely excited astir the support of this cause successful Canada, saying, “We haven’t had a breakthrough similar this successful presumption of a caller cause successful astir 20 years.”

However, she noted that immoderate questions remain. Doctors inactive don’t cognize the semipermanent endurance outcomes for patients taking the drug, oregon whether definite groups of patients mightiness respond amended oregon longer to the treatment.

“But nonetheless, we deliberation it is simply a large breakthrough and large advancement successful presumption of providing much options for patients,” she said.
