Ottawa cancer researchers and clinicians embrace the window of opportunity between a cancer diagnosis and treatment with a coordinated approach to clinical research
The time between a patient’s cancer diagnosis and their surgery presents a valuable “window of opportunity” to evaluate new treatment strategies. Short-term clinical trials during this period – also known as window of opportunity trials, window trials or phase 0 trials – can help researchers gain insights into the effects and the efficacy of a new potential treatment. Dr. Angel Arnaout at The Ottawa Hospital is putting window trials into practice.
“There are many nervous and anxious moments between diagnosis and their surgery but patients have limited options during this time,” says Arnaout.
“We saw an opportunity in this window of time to take action. We saw that we could help support patients who are waiting for surgery, while helping future patients through accelerating clinical research.”Dr. Angel Arnaout
Arnaout, a surgical oncologist who specializes in breast cancers, assembled a cross-disciplinary team of medical oncologists, pathologists and other clinical research specialists at The Ottawa Hospital to strategically design and implement this new approach. They would collectively establish common priorities, decide on which interventions would be tested and work to streamline the patient’s journey throughout the process.
Together, the team was motivated by the mutual benefits of all stakeholders involved. Namely, window trials can provide patients an opportunity to contribute and engage with cancer research while potentially improving the state of a patient’s disease. Meanwhile, these trials could ultimately expedite drug development by improving the understanding of a potential drug early in its development.
The team launched their first study in 2014, which found that patients were exceptionally eager to participate, and since then, launched and completed three additional window trials.
The first was a breast cancer trial on presurgical hormone therapy that helped establish the capacity and infrastructure for enrolling patients, organizing the investigations and giving patients short-term therapies. The second tested a potential cancer-fighting agent, chloroquine, and found that it had no effect on stopping breast cancer proliferation. The third trial debunked the idea that vitamin D – even at very high doses – can slow down the growth of breast cancer.
“These studies didn’t uncover a new therapy, but they did help us answer important questions that patients have, like ‘Will taking vitamin D help?’” says Arnaout. “These types of studies also provide a relatively quick method to test whether we should continue research into a particular avenue.”
The group at The Ottawa Hospital has recently teamed up with researchers from OICR to initiate a new breast cancer window-of-opportunity study to examine biomarkers of efficacy and resistance for another new drug candidate. The trial is planned to begin recruitment by mid-fall this year.*
Despite the benefits of these trials, Arnaout adds, it is still important to reduce unnecessary delays between diagnosis and surgery. Arnaout continues to minimize these delays at The Ottawa Hospital.
“We try our best to reduce wait times, but if patients have to wait – we can try to help them in the meantime while accelerating breast cancer research.”
*This new trial is co-led by Dr. John Hilton from The Ottawa Hospital and Dr. John Bartlett from OICR. Co-investigators include Drs. Laszlo Radvanyi, Melanie Spears, Arif Ali Awan, Mark Clemons, Greg Pond and Angel Arnaout.

OICR researchers have recently teamed up with a team of medical oncologists and surgeons at The Ottawa Hospital to launch a new breast cancer clinical trial – one that begins before a patient undergoes surgery.
“There’s a gap between when a patient is diagnosed with cancer and the start of their surgery,” explains Dr. Melanie Spears, trial co-investigator and Principal Research Scientist at OICR. “A window of opportunity study allows us to use this gap to look at novel targeted therapies.”

Genome Canada, Ontario Institute for Cancer Research and Thermo Fisher Scientific to focus on pancreatic, prostate and breast cancer
CARLSBAD, Calif. – (July 30, 2019) – Genome Canada, the Ontario Institute for Cancer Research (OICR) and Thermo Fisher Scientific are collaborating to develop a complete solution of targeted next generation sequencing (NGS) assays and analysis software designed to more effectively assess – and eventually improve management of – pancreatic, prostate and breast cancer.
The $6 million, three-year initiative aims to standardize advanced molecular profiling in these disease areas and make the assays commercially available globally. Focusing on rapid genomic diagnostics in pancreatic cancer and targeting treatment in breast and prostate cancers, the partnership builds on previous clinical research between OICR and Thermo Fisher and will inform development of three assays that will be utilized to stratify patients in clinical trials in Ontario and other jurisdictions.
“By supporting research and clinical trials, Genome Canada is helping to put more of Ontario’s innovative cancer diagnostics research into clinical use,” said Dr. John Bartlett, program director, diagnostic development at OICR. “This project has the potential to springboard advanced next-generation sequencing to routine clinical use in Ontario and across Canada.”
Breast and prostate cancer are among the most common types of cancer in Canada, and the country’s five-year net survival rate for pancreatic cancer is only 8 percent. However, there is clear evidence that patient outcomes can be improved with NGS-based testing strategies. A recent U.S. health economics study has shown that advanced cancer patients who received treatment based on NGS testing results experienced double the length of progression-free survival without increasing health care costs.1
While some solutions analyze only DNA sequences, the new targeted NGS assays will provide comprehensive genomic profiles by simultaneously assessing DNA and expression signatures from RNA to provide significantly more insight into driver mutations. The OICR/Thermo Fisher team will leverage this advantage by supplementing the new assays with unique DNA/RNA stratification biomarkers – specific to pancreatic, prostate and breast cancer – previously qualified by OICR translational researchers.
The collaboration is partly funded with a grant from Genome Canada through the Genomic Applications Partnership Program (GAPP). Genome Canada will contribute $2 million, the highest possible level of funding support, with the balance split between OICR and Thermo Fisher, which will cover development costs and validation activities.
Previous research collaborations led by OICR and Thermo Fisher are already well on their way to impacting cancer treatment in the future. Of particular note is a 2016 study designed to identify mutations and copy number variation changes in breast cancer, and clinical research utilizing the Oncomine Comprehensive Assay, which also supports both the National Cancer Institute’s Adult and Pediatric MATCH trials in the United States.
“OICR is a leader in clinical research, with extensive clinical trials in progress to improve care for patients with pancreatic, prostate and breast cancer,” said Jeff Smith, global lead of NGS precision medicine initiatives, clinical NGS and oncology for Thermo Fisher Scientific. “When OICR approached our team with the idea for this project, we saw it as another exciting for opportunity to bring Thermo Fisher’s proven Ion Torrent technology to clinical laboratories across Canada and to contribute to future improvement of patient care.”

Sometimes the simpler, the better: bringing personalized treatment selection for bladder cancer closer to the clinic
Pathology experts review challenges and opportunities in treatment selection for muscle-invasive bladder cancer (MIBC), propose traditional pathology method to achieve same results as molecular profiling at lower cost
Research has shown that some types of bladder cancer respond well to treatment and other types are resistant, yet molecular subtyping, which can help better define a patient’s cancer and direct them to a more targeted treatment, is not performed in the clinic. This means that patients are often treated with a one-size-fits-all approach. Despite recent research progress, the movement of MIBC subtyping to the clinic has stagnated.Continue reading – Sometimes the simpler, the better: bringing personalized treatment selection for bladder cancer closer to the clinic

Research team finds aggressive breast cancers are less frequent than previously thought, and less aggressive breast cancers need more of our attention.
Different subtypes of breast cancer respond to treatment differently and require different treatment approaches. Understanding the distribution of these subtypes and their respective clinical outcomes allows researchers to better understand the disease and identify key research priorities that may have been previously overlooked.

OICR takes part in international multicentre study to standardize promising breast cancer digital pathology test
The Ki67 immunohistochemistry assay is a test that can help evaluate the aggressiveness of breast tumours, predict disease outcomes, monitor cancer progression and identify patients who are more likely to respond to a given therapy. Despite its potential to help patients with breast cancer, the analysis of Ki67 has not been widely adopted in the clinic, mostly due to the lack of standardization across laboratories.

Endocrine therapy uses hormone antagonists to greatly reduce the risk of disease recurrence in women with early-stage, estrogen-receptor (ER) positive breast cancer. However, the treatment can come with severe side effects. Around 30 per cent of women stop taking the therapy after three years largely due to these negative impacts. Usually patients receive the hormone therapy for five years following initial treatment (e.g., chemotherapy, surgery), but it can also be taken longer-term. A central question facing patients and clinicians is how to balance, in their decision making, the side effects of long-term treatment with the potential reduction in recurrence risk. In short, they want to know: ‘is it worth it?’
