As our researchers move new research projects forward faster than ever in an effort to address COVID-19, donations to the COVID-19 Emergency Response Fund continue to provide seed funding to get these vital projects off the ground. Below are some of the new and promising projects approved for support through the second round of funding. Kick-starting these projects would not have been possible without the support of our generous donors — thank you!
Harnessing cancer-fighting viruses to develop a COVID-19 vaccine
Drs. Carolina Ilkow, John Bell and colleagues are harnessing their expertise in making oncolytic (cancer-fighting) viruses to develop a vaccine against COVID-19, in partnership with scientists and clinicians in Canada and around the world. One of the key things they’ve learned is that the best cancer-killing viruses also stimulate the body’s own immune system – in effect, training the immune cells to recognize and help attack the cancer cells.
They have developed a number of viruses that are very good at boosting the immune system and have already been tested safely in people. These viruses will be reengineered by splicing in key genes from the COVID-19 virus to create several candidate vaccines, which would train the body to mount an immune response against COVID-19. They expect this live vaccine will be particularly important for healthcare workers and vulnerable populations, including people with cancer. Once the vaccine is created, large quantities can be made in The Ottawa Hospital’s Biotherapeutics Manufacturing Centre.
“We know that people with cancer who get COVID-19 are much more likely to get severely ill, so we think that working on a vaccine is the best thing we can do right now to help cancer patients.”
– Dr. John Bell
The research team has developed candidate vaccines and laboratory testing is going well. With funding, the team will be ready to do human clinical trials in the new year.
Creating a new mouse model to study COVID-19 lung disease
Drs. Manoj Lalu, Duncan Stewart and colleagues are working to develop a mouse model of COVID-19 that mimics the severe lung disease seen in humans.
The lack of good, accessible animal models of this disease is severely limiting research around the world. The COVID-19 virus doesn’t infect regular lab mice very well, and the virus is dangerous to work with because it is so contagious for humans.
Drs. Lalu are Stewart are working with Drs. Carolina Ilkow and John Bell, who are creating a novel hybrid virus that features a key protein from the COVID-19 virus (the spike protein) embedded into a well-studied and safe virus called vesicular stomatitis virus (VSV).
The team will test this hybrid virus in mice that have been genetically engineered to be more susceptible to COVID-19, to mimic the severe lung disease seen in humans.
To make sure the model is accurate, they will use sophisticated techniques to compare their findings in mice with findings from patients, focusing on effects on the lungs, blood and blood vessels. They will then use this model to test new therapies, including mesenchymal stromal cells.
A novel hybrid virus (VSV-Cov2-S) has been manufactured by Dr. Ilkow’s lab with high quality and concentration to proceed with testing in our mouse model. Our experts have worked with the uOttawa Animal Care Committee and have successfully obtained ethics approval. Researchers began challenging ACE2 transgenic mice with the virus in December, controlling for time and dose, and assessing lung injury outcomes.
Studying the immune response of COVID-19 patients in the ICU
Why do some people get severely ill and die of COVID-19, while others experience only mild symptoms? Part of the answer may lie in how an individual’s immune system reacts (and sometimes over-reacts) to the COVID-19 virus. Dr. Shirley Mei and her intensive care research colleagues will study this in critically ill COVID-19 patients using the world’s most advanced “single-cell proteomics” technology.
This technology, called CyTOF, will allow the researchers to study up to 60 different biological factors all at the same time from one single cell. The researchers will create a multi-dimensional map of the immune response to COVID-19, showing how it changes over time and how it sometimes goes out of control.
The data will be shared with clinicians and researchers around the world, in order to improve treatment of COVID-19 and save lives.
Patients participating in this research study will have blood samples taken for a period of 15 days after their enrollment and consent to participate. With approval from the research ethical board, researchers are in the process of recruiting patients into four arms of our study: septic patients in ICU (control cohort), COVID-19 patients in ward (mild disease cohort), ICU patients with severe COVID-19 (severe disease cohort), as well as healthy volunteer (healthy cohort). To date, 34 patients have been recruited with a total of 147 blood samples collected. Pilot experiments to validate the customized immune profiling panel for the mass cytometry (CyTOF) experiment have been completed. This approach will allow researchers to assess the disease progression by using the world’s most advance single-cell proteomics technology.
A balancing act: how to provide regular patient care amid the threat of COVID-19
Dr. Kednapa Thavorn and colleagues will use health administrative data from across Ontario, available through IC/ES, to model the risks of various scenarios for restarting routine clinical procedures in hospitals. Ontario hospitals have postponed many routine clinical procedures in order to preserve resources for COVID-19 patients, but these routine procedures can’t be postponed forever without serious health consequences.
As hospitals contemplate re-staring some routine care, a careful balance will need to be struck between the risks of COVID-19 and the risks of all other preventable diseases and conditions. The model will estimate overall deaths, healthcare costs and other factors for several scenarios, in order to help hospital administrators and policy makers make evidence-based decisions. The model could be adapted for different regions and for different COVID-19 scenarios, including a possible second wave.
Researchers working on this project have developed a detailed protocol of the study and a model structure for a resource optimization model. They have requested the hospital data required for the model and expect to receive this information in January.
Helping COVID-19 survivors stay healthy
Drs. Sara J. Abdallah, Juthaporn Cowan and colleagues will study the long-term effects of COVID-19 in survivors, checking in on them three, six and 12 months after they were initially infected. While researchers are beginning to understand what happens in the body during a severe COVID-19 infection, much less is known about the long-term effects in survivors. But based on what is known about other viral infections, the long-term effects could be serious, affecting the lungs, heart and muscles, as well as mental health. Survivors of mild, moderate and severe infections will be included in the study. The researchers will also assess the healthcare resources used by survivors. Results will help improve care for COVID-19 survivors and optimize how healthcare resources are used.
With support from The Ottawa Hospital COVID-19 Emergency Response Fund, researchers set out to understand the medium and long-term impact of COVID-19 on overall health. As of October 31, 2020, 64 enrolled participants completed comprehensive cardiopulmonary testing and important progress has been made in understanding the residual effects of COVID-19 on heart and lung function. As patients continue to be monitored at six and 12-months after COVID-19 infection, our researchers hope that their findings will inform future management strategies for post-COVID breathlessness.
World-first clinical trial aims to protect cancer patients from COVID-19
Surgeon-scientist Dr. Rebecca Auer is leading a world-first clinical trial that she hopes will protect cancer patients from COVID-19 and other respiratory infections by boosting their immune systems during treatment.
In collaboration with scientists at the Ontario Institute of Cancer Research, researchers will explore an immune-stimulator called IMM-101. The trial will be designed and run by the Canadian Cancer Trials Group at Queen’s University at nine cancer centres across Canada and will recruit 1,500 patients currently receiving cancer treatment.
This trial takes advantage of a lesser-known aspect of the immune system — innate immunity. This first-response arm of the immune system plays a key role in detecting viruses. The research team hopes the IMM-101 treatment will train the patient’s innate immune system to fight off the COVID-19 virus, in addition to other viruses that cause respiratory infections.
The advantage of this immune-boosting approach is that it could help cancer patients fight off all sorts of viruses while they are undergoing cancer treatments and are at their most vulnerable.
The trial has been approved by Health Canada and will run this summer and into the fall. Researchers expect to see preliminary results in about nine months.
The clinical trial was activated in September and is now open in Ottawa for recruitment. The trial will enroll 1,500 patients across Canada, with approximately 200 patients from Ottawa. These Ottawa patients will be part of the translational study funded in part by the COVID-19 Emergency Response Fund.
“While there are many specific vaccines for COVID-19 in the works, they won’t be available for at least a year. Cancer patients need protection now.”
– Dr. Rebecca Auer
