We talked to Karim Vermaelen, Phd, MD, R&D Lead Scientist, Dendritic Cell Immunotherapy Development of the Tumor Immunology Laboratory, Dept. of Pulmonary Medicine of Ghent University, Belgium. His preclinical research focuses on the interactions between lung cancer and the immune system with a special focus on dendritic cells. He recently announced a major milestone: the filing to the authorities of some dendritic cell vaccine candidates and related phase 1 clinical trial protocols. Let’s hope now for a positive review. We talked to him about progress in the field of immuno-oncology.

Below you can read the full interview.

How far are we in the effort of beating cancer? 

Prof. Vermaelen: We haven’t beaten cancer yet, but we have come a very long way and I am speaking from my expertise as a lung cancer specialist. It’s a cancer which always has been very tough to treat. And we have seen some major advances over the past 10 years. For a minority of lung cancers that have specific mutations, which are also the Achilles heel of the tumor. We have specific drugs that target these mutations and we see dramatic responses. But these patients are not cured. And then came the immunotherapies, for the patients without these mutations, they have remarkable activity. So we are progressing really fast, but we are not there yet. Immunotherapy doesn’t work for all cancer patients.

Will we someday be able to beat lung cancer?

Prof. Vermaelen: The only thing I can say is that every few years we see an incremental step. We are seeing that now for immunotherapy. We are entering an era of next-generation immunotherapy, where drugs are combined together to achieve even more response.

Where do you expect most of the breakthroughs? In the field of immuno-oncology?

Prof. Vermaelen: Yes, I think so. What we observe in some patients is really remarkable. Patients that have been declared incurable, with lots of metastasis, some of them – some of my patients also – are still alive for 4 years or more. This is amazing, this is incredible. So I think conceptually it’s a different thing, it’s revolutionary, the approach is revolutionary, but it has to be combined with other drugs and what we have seen now, is that more and more drugs that have not been designed for immunological purposes, we have discovered that they have immunological effects that are interesting, that can complement the immuno-oncology drugs, in combination.Some patients that have been declared incurable are still alive for 4 years or more.

What promise does immunotherapy hold for the future?

Prof. Vermaelen: The promise and what we are already seeing now is very durable responses, very durable remission. What’s also very interesting is that patients who do well with immunotherapy, their quality of life is good. With some other drugs, they stay long on the drugs, but have so many side effects that the balance is not right. Immunotherapy is better, you can resume normal activities, this is important.

Can we also expect a breakthrough from cancer vaccines?

Prof. Vermaelen: That’s a very good question, because cancer vaccines have very often failed in oncology. But now thanks to the convergence between immunology and genomics, we will see a revival in cancer vaccines. Because now we know what the real targets are of the immune system. We didn’t have the right targets and probably also not the right vectors to vaccinate. Now we combine these new assets with new insights into immunology. Because immunology has evolved as well. And we are going to see major breakthroughs in cancer vaccines. Possibly in combination with the current immuno-oncology drugs.We are going to see major breakthroughs in cancer vaccines.

What’s your team and you focusing on?

Prof. Vermaelen: The main efforts of my team right now is to finish the development of a vaccine, it’s a cellular vaccine, so we use the body’s own immune cells, we load them with specific targets that are common to a large set of lung cancers and we re-infuse them in the patient and this boosts the immune system.

Patients with severe lung cancer?

Prof. Vermaelen: Patients with metastatic lung cancer. Progressively, I hope we find enough financing to progress into more larger trials in the future.

What impact do you expect from this work in the future?

Prof. Vermaelen: I think it has the potential to as I said not all patients respond the current generation of immuno-oncology drugs, I think the combination with a vaccine will boost these responses and help rescue more patients.

So more patients will benefit?
Prof. Vermaelen: Yes, with very low toxicity.

What’s your personal moonshot?

Prof. Vermaelen: My personal moonshot is to crack the immunological code of lung cancer. And really find the way to define for each patient which is the ideal combination therapy to use. And we are not there yet, we need new technologies, combination of technology also in machine learning to really integrate this complexity of the cancer immune interaction to distill information that is useful for the doctor to decide which combination therapy should be given.My personal moonshot is to crack the immunological code of #lungcancer says @KarimYV @Ugent Click To Tweet

It’s really about personalized medicine?
Prof. Vermaelen: It’s personalized. Also for immuno-oncology.
