  • Cancer patients treated in world-first clinical trial of viral therapy

    Terry Fox-funded researchers are key members of a Canadian team to have launched the world’s first clinical trial of a new therapy that uses a combination of two viruses to attack and kill cancer cells, and stimulate an anti-cancer immune response. Previous research by this team and others worldwide suggests that this approach could be very powerful, and could have fewer side effects than conventional chemotherapy and radiation, although it will take years to rigorously test through this trial and others.

    The therapy was jointly discovered and is being developed by Dr. David Stojdl (Children’s Hospital of Eastern Ontario, University of Ottawa), Dr. Brian Lichty (McMaster University) and Dr. John Bell (The Ottawa Hospital, University of Ottawa), and their respective research teams and colleagues. Drs. Bell, Lichty and Stojdl are principal investigators on the Terry Fox Program Project Canadian Oncolytic Virus Consortium (COVCo), which has been key to developing the anti-cancer viruses.

    The clinical trial, which is funded by the Ontario Institute for Cancer Research and coordinated by the NCIC Clinical Trials Group, is expected to enroll up to 79 patients at four hospitals across Canada. Up to 24 patients will receive one of the viruses and the rest will receive both, two weeks apart.

    Christina Monker, 75, a former nurse from Rockland, Ontario, is one of the first patients treated in the trial. She was diagnosed with cancer in 2012 and, despite six weeks of radiation therapy and more than 30 rounds of chemotherapy, the cancer spread to both her lungs. She enrolled in the trial at The Ottawa Hospital and was treated on June 2, 2015.

    “The nausea of chemotherapy was worse than I ever could have imagined, but with the viral therapy I just felt like I had the flu for a couple of days, and the symptoms were easily managed,” said Ms. Monker. “It is too soon to know if I may have benefited from this therapy, but I’m very glad to contribute to this important research that could improve care for others.”

    The idea of using viruses to treat cancer has been around for more than a century, with sporadic reports of cancer patients experiencing remarkable recoveries after viral infections. However, it is only in recent years that viral therapy has begun to be developed and tested in a rigorous way. Drs. Bell, Lichty and Stojdl began investigating viral therapies for cancer nearly 15 years ago and have been funded by The Terry Fox Foundation since 2004.

    “We found that when normal cells become cancerous, it’s like they are making a deal with the devil,” explained Dr. Bell, Project Leader on the Terry Fox Program Project Grant and a senior scientist at The Ottawa Hospital. “They acquire genetic mutations that allow them to grow very quickly, but these same mutations also make them more susceptible to viruses.”

    The two viruses being tested in this clinical trial are called MG1MA3 and AdMA3. MG1MA3 is derived from a virus called Maraba, which was first isolated from Brazilian sandflies, while AdMA3 is derived from a common cold virus called Adenovirus. Both of these viruses have been engineered to stimulate an immune response against cancer cells that express a protein called MAGE-A3, but the Maraba virus also achieves an extra layer of anti-cancer activity by replicating inside many kinds of cancer cells and killing them directly. These viruses are manufactured in specialized facilities at The Ottawa Hospital and McMaster University.

    “The idea behind this trial is to use the Adenovirus to prime the patient’s immune system to recognize their cancer, and then use the Maraba virus to directly kill their cancer and further stimulate their immune system to prevent the cancer from coming back,” explained Dr. Brian Lichty, associate professor at McMaster University. "We're enthusiastic about the potential of this unique therapy."

    “We’re very excited about this first clinical trial,” said Dr. Stojdl, senior scientist at the Children’s Hospital of Eastern Ontario and associate professor at the University of Ottawa. “We’re continuing to push very hard to develop a suite of biological therapies with the goal of launching similar trials tailored to other types of tumours, including brain cancer and several devastating childhood cancers.”

    Viral therapies are one component of a growing field of cancer research that seeks to use biological materials (including cells, genes, antibodies and viruses) to attack cancer cells and stimulate an anti-cancer immune response. This field of research has been called biotherapy or immunotherapy. Dr. Bell and his colleagues recently launched the $60M BioCanRx network to advance this area of research.

    The Maraba virus is an important part of a broad biotherapeutics clinical trial development program in Canada that is combining viruses and vaccines with standard and emerging therapies to treat different types of tumours.

    In addition to The Ottawa Hospital, the clinical trial is also taking place at the Juravinski Cancer Centre of Hamilton Health Sciences (under the leadership of Dr. Sebastien Hotte), Princess Margaret Cancer Centre of the University Health Network in Toronto (under the leadership of Dr. Albiruni R A Razak) and the Vancouver Centre of the BC Cancer Agency (under the leadership of Dr. Daniel Renouf). The trial was approved by Health Canada, the Ontario Cancer Research Ethics Board and the BC Cancer Agency Research Ethics Board. Further details about the trial are available at clinicaltrials.gov. Patients wishing to participate in the trial should speak with their own oncologist and ask for a referral to one of the participating hospitals. Further details for patients at The Ottawa Hospital are available online.

  • Cancer cases set to rise

    by TFRI Admin | Jun 03, 2015
    The Canadian Cancer Society has released data showing an expected rise in the number of cancer cases over the next 15 years. The society's annual Canadian Cancer Statistics report, released at the end of May, states that the large rise in cases will be largely due to an aging Canadian population. The risk of developing cancer is expected drop slightly for men and increase slightly for women. Read the full news story.

  • Viruses and drugs combine to form potent anti-cancer therapy

    by TFRI Admin | Apr 23, 2015

    Ottawa, ON -- Terry Fox-funded researcher, Dr. Jean-Simon Diallo and his colleagues at the Ottawa Hospital Research Institute have discovered that compounds that disrupt our cells’ inner skeleton (called microtubule-destabilizing agents) can greatly enhance oncolytic virus cancer therapy in mouse and cell culture models. As described in Nature Communications, it appears that our cells’ inner skeleton plays a crucial role in making an anti-viral protein called interferon, so disrupting this skeleton also reduces the anti-viral defences of the cells. The combination therapy also seems to increase “bystander” killing of uninfected cancer cells without harming normal cells.

    Microtubule-destabilizing agents have been used to treat cancer for many years and oncolytic viruses are currently being tested in clinical trials, so it would be feasible to test these therapies together in a clinical trial in the near future.
