Getting genomics into healthcare: look to the UK

Discussing health care at Cancer Crosslinks 2019

During Cancer Crosslinks 2019, one thing was crystal clear: there is a need to include broader genomic testing into treatments for cancer patients in Norway.

“We are lacking behind here in Norway!”

Professor Ola Myklebost, from the Department of Clinical Science at the University of Bergen, was definitely ready for action in the panel debate at Cancer Crosslinks 2019, fittingly named “Call for Action”.

The panel and the audience of about 300 people had just listened to the talk given by James Peach. He is the Precision Medicine Lead at UK Medicines Discovery Catapult, Alderly Park, and prior to this, he was the Managing Director at the main programme for Genomics England from 2013 to 2017 and led the UK’s Stratified Medicines Program.

Peach told the audience how they have been implementing precision medicine into the public health care system (NHS) in the UK, using genomic testing, during the last decade. He demonstrated how the industry is part of this public endeavour, how political support and investment contributed to industry development, and how they addressed complex issues like sharing health data and using artificial intelligence.

It started with very little.

“In 2010, we had no structure”, Peach told the audience.

Sequencing 100,000 genomes

Thanks to all the British cancer patients who consented to Genomics England using their data, and a lot of common public-private efforts, Genomics England has now reached its goal of sequencing 100,000 whole genomes from NHS patients, according to their webpage. It takes a lot to accomplish this number, but luckily there are things to learn from the UK effort.

“Circulating tumour DNA testing is absolutely necessary”, Peach said from the podium.

The Life Science Sector deal from the British government outlines this public-private effort. It shows how significant government commitment, funding and strategic actions triggered investment and initiatives from the life science industry. You can read the entire document at the official webpage of the British Department of Business, Energy and Industrial Strategy, following this link.

James Peach visited Norway earlier as a speaker at Cancer Crosslinks 2012. Returning now, he was truly surprised about the current state of precision medicine in Norway.

 

Concerned about Norway

In an interview with Oslo Cancer Cluster, James Peach shared a concern as an answer to the question “What impressions are you left with after this conference?” 

“It has left me quite concerned about the state of precision medicine in Norway. I thought you would be looking forward to the things you could do, but it turns out that there are actually some things that you should have done already.”

“Like what things?” 

“Like universal application of a cancer panel test that is commercially feasible and deals around getting your data shared appropriately.”

Do you think we can have a Genomics Norway?”

“Of course. It is probably about combining two things. One is that you got to get the basic stuff right. People need to have access to gene tests for their clinical care. Luckily the people here are a group of experts who are all connected to each other and who understand the system. It is not a massive system. I think there is a real chance to choose an area where Norway could do it exceptionally well. What that area is, is for you to choose.”

 

Concerns in Norway

Back in the panel discussion, Hege G. Russnes, Pathologist, Senior Consultant and Researcher at Oslo University Hospital, was getting involved:

“We need more information to help clinicians make therapy decisions. (…) Norway has no plan or recommendation for multi gene tests.”

Christian Kersten, Senior Consultant at the Center for Cancer Treatment at Sørlandet Hospital, agreed.

“I’m the clinician, I treat patients, patients die because of metastasis. I have been treating cancer patients for 20 years now and I feel it increasingly difficult to keep the trust of the patient.”

“If you ask the patients, they will sign the papers with consent of sharing data in 99% of the cases”, Myklebost added.

“We are only 5 million, we do not have to reinvent the wheel. Erna Solberg should invite James Peach for a cup of tea”, Christian Kersten said, finishing up the panel talk.

New research: 3D structure tumors in immunotherapy

Researcher testing lab sample.

New work from cancer researchers at the Department of Cellular Therapy could help to streamline the development of exciting new immunotherapy approaches for treating cancer.

Cancer treatments that aim to switch on a patient’s immune system to kill tumor cells – so-called immunotherapy approaches – have received much attention and encouraging results in recent years. Now, the immunomonitoring unit of the Department of Cellular Therapy at Oslo University Hospital has devised a new experimental approach that could improve early stages of the immunotherapy development pipeline.

The unit is present in Oslo Cancer Cluster Incubator with a translational research lab, led by Drs. Else Marit Inderberg and Sébastien Wälchli.

CAR T cells drive new successes

Our immune systems are generally very good at recognizing foreign infectious agents and disposing of them appropriately. However, although our immune systems are capable of recognizing tumors as a threat, cancer cells have adapted mechanisms that enable them to evade the immune response. Immunotherapy is the name given to a range of different approaches that aim to overcome this problem by improving the immune system’s ability to target cancer cells.

One relatively new example of an immunotherapy approach comes from CAR T cells. These are produced by isolating specific cells of the immune system (T cells) from a cancer patient and modifying them so that they become more effective at recognizing and killing cancer cells. The modified T cells are then placed back into the patient so that they can ‘home in’ on the tumor and kill the cancer cells.

Difficult for solid cancers

Current models for testing new CAR T cells aren’t always optimal. Although CAR T cells have shown encouraging results in treating some cancers, particularly the blood cancers leukemia and lymphoma, the development of CAR T cells for non-blood, or ‘solid’, cancers has been more difficult.

In part, this is due to the fact that tumor models currently used in early stages of testing involve two-dimensional monolayers of cancer cells, which do not reflect the complex three-dimensional structure and organization of solid tumors found in patients.

Consequently, CAR T cells that show encouraging results using these two-dimensional models often produce less effective results at later stages of the development pipeline, meaning time, effort and resources are wasted.

 

3D tumor spheroids

To improve the early stages of testing new CAR T cells, Dr. Wälchli’s group has developed a new approach that enables researchers to grow three-dimensional cancer cell structures, or ‘spheroids’, in the lab, and to test the effect that CAR T cells have on killing off these spheroids.

Compared to current two-dimensional methods, the spheroids are more similar in complexity and structure to tumors found in patients.

In a recent publication in the Journal of Visualized Experiments, this group demonstrated for the first time that their spheroid approach has the potential to provide a useful new tool for developing CAR T cells.

They generated spheroids using colorectal cancer cells – a type of cancer for which there is currently no effective CAR T cell therapy available. These cancer cells were modified so that they possessed a molecule on their cell surface called CD19, which is known to be recognized by certain CAR T cells. The researchers then incubated these spheroids with CD19-targeting CAR T cells and used advanced live imaging techniques to track the effect on cancer spheroids.

To help other research groups who would like to start using the spheroid technique, Dr. Wälchli’s publication is accompanied by this video which introduces the approach and provides a basic overview of how it works. The Journal of Visualized Experiments requires a subscription to see the entire video. You can also read a PDF of the article “A Spheroid Killing Assay by CAR T Cells” without a subscription.

 

Successful approach

As expected, shortly after adding CAR T cells, the researchers could detect that spheroids were shrinking due to cancer cell death, proving that their approach successfully measures CAR T cell-induced tumor clearance in a quantitative manner.

Discussing the work, Dr. Wälchli says, “We believe this method can help to answer key questions about using 3D structure tumors as a suitable alternative for testing new immunotherapy approaches.”

The approach now opens the door for testing a range of different target molecules in combination with new CAR T cells targeting those molecules.

 

Fast, affordable and straightforward

Dr. Wälchli believes many researchers could benefit from the spheroid technique. He continues,

“A major advantage to our approach is that it is fast, affordable and straightforward, meaning any research group with the right equipment can test the effect of their immunotherapy on 3D tumors before moving to animal models”.
