Ottawa researchers discover a new way to make cancer cells more susceptible to virus-based therapies
Over the past decade, researchers have made significant progress in designing oncolytic viruses (OVs) – viruses that destroy cancer cells while leaving healthy tissue unharmed. However, some cancer cells are resistant to this type of therapy and their resistance mechanisms remain poorly understood.
Researchers at the The Ottawa Hospital and University of Ottawa, under the leadership of Dr. Carolina Ilkow, have discovered that a common cellular mechanism, RNAi, allows cancer cells to fight back against cancer-fighting viruses. Their findings, recently published in the Journal for Immunotherapy of Cancer, show that blocking RNAi processes in tumours can make cancer cells more susceptible to OVs.

New OICR President and Scientific Director comments on breakthrough in breast cancer T-cell immunotherapy
For the first time, a patient’s late-stage breast cancer has been successfully treated with T-cell immunotherapy. This cutting-edge approach, which is currently in clinical trials in the U.S., modified the patient’s naturally-occurring immune cells to fight her tumours that had spread throughout her body. The patient has been cancer free for the past two years and her remarkable tumour regression represents the potential impact of this new immunotherapeutic approach.

Some common pathogens, like the Epstein-Barr virus (EBV), can turn healthy cells into cancer cells, but it is not well understood how they do so. Better understanding how such pathogens work allows researchers to find new ways to target the pathogen’s disease-causing mechanisms and ultimately find new treatments for certain virus-induced cancers.
Dr. Ivan Borozan, from Dr. Vincent Ferretti’s Lab at OICR, and Prof. Lori Frappier at the University of Toronto are working together to better understand EBV and how it triggers the transformation of normal cells to cancerous cells, also known as oncogenesis. Together, they have identified that a key protein expressed by EBV, BKRF4, is one of the likely drivers behind EBV-induced stomach cancers.

Combination of erectile dysfunction drugs and flu vaccine may help kill remaining cancer after surgery
A remarkable study led by Dr. Rebecca Auer from The Ottawa Hospital (TOH) shows that the unlikely combination of erectile dysfunction drugs and the flu vaccine may boost the immune system’s ability to clean up cancer cells left behind after surgery. This method demonstrated promising results in a mouse model, where it reduced the spread of cancer following surgery by 90 per cent. Now the approach will be tested in a first-of-its-kind clinical trial involving 24 patients at TOH.

Immunotherapy, which boosts the body’s immune system to kill cancer cells, has shown remarkable promise in treating many types of cancer. Now researchers have found a way to use immunotherapy against triple-negative breast cancer (TNBC), one of the most lethal forms of breast cancer. Previously, TNBC was resistant to immune checkpoint inhibitors, a common class of immunotherapies. Using a new strategy, the scientists achieved a cure rate of up to 90 per cent in mouse models.

Researchers at The Ottawa Hospital and the University of Ottawa have found that a combination of two immunotherapies – oncolytic viruses and checkpoint inhibitors – was successful in treating triple-negative breast cancer in mouse models. Triple-negative breast cancer is the most aggressive and hard-to-treat form of the disease.

The body’s immune system is incredibly powerful. Its ability to detect and destroy various pathogens makes it central to maintaining good health. While we all know the role it plays in fighting the common cold or flu, many do not know that it has recently been enlisted by scientists in the fight against cancer. Researchers in a field known as immuno-oncology are working to find ways to turn on the body’s defences to locate and destroy tumour cells. OICR recently established a team of expert scientists and clinicians to develop and test new immunotherapies to help patients.
