In our latest thought leader interview we explore the intersection between epigenetic therapy and immunotherapy.

Gems from the ASCO17 poster hall

Much of the IO focus to date has been on monotherapies rather than combos, although that situation is slowly changing.

What we can also expect to see are the emergence of regimens, long the bedrock of traditional cancer therapy approaches.

As we learn how to bucket more discrete populations based on the underlying biology of the tumour microenvironment, so we will see a more IFTTT (If this then that) approach evolve in order to fix or improve a situation before or after attempting the core therapy. It might require a focus on changing the immunosuppressive or inhibitory factors, for example, or addressing factors that induce primary resistance upfront. The possibilities are endless.

Obviously, there are a number of ways to do this from chemotherapy and radiotherapy to epigenetic agents to targeted therapies – these traditional treatments are not going to go away, but I can see a future where we see more integration based on a patient’s underlying immune status. It won’t be the zero sum game many analysts seem to think it might be.

In the past, we have covered chemotherapy, radiotherapy and targeted therapies and looked at how they might be employed with immunotherapies in various guises. In this latest thought leader interview, we look at a different approach, epigenetic therapy and other novel immunotherapies.

Here, we combine two popular types of posts – Gems from the Poster Halls with an Expert Interview  – for detailed look at one particular area of research that is beginning to look quite intriguing.

Sarcomas are a heterogeneous type of cancer that develop from certain tissues like bone or soft tissues such fat, muscle, nerves, fibrous tissues, blood vessels, or deep skin tissues.

Over the last two years, much has happened in this space so it’s an excellent time to revisit the niche and learn more about what experts think of the latest data that is emerging here.

We put a sarcoma expert in the spotlight and learned what their perspectives are on some of the emerging data in this niche as well as which ones offer hints of promise.

At the AACR 2017 annual meeting, there was a surprising amount of early clinical data on offer, particularly in the field of cancer immunotherapy.

A shortage of reliable preclinical models that predict human response to cancer immunotherapy has led to a mad rush to the clinic to do trials in man – thee are now over 800 combination trials – if anyone wants to try and follow them all!

If you missed it do listen to the Of Mice and Men” episode of the Novel Targets Podcast recorded at AACR 2016 that features experts such as Dr Bernard Fox (@BernardAFox) and Professor Cornelius “Kees” Melief (Leiden) who discuss the challenges of mouse models.

Several thought leaders at this year’s AACR annual meting described it as “mini ASCO” given the focus on clinical data, with several plenary sessions devoted to the results of early trials.

Dr Julie Brahmer at AACR17 in Washington DC

At AACR17, Dr Julie Brahmer, a leading lung cancer expert and an Associate Professor of Oncology at the Johns Hopkins Bloomberg Kimmel Institute presented long-term survival data for nivolumab in second-line non-small cell lung cancer (NSCLC).

The 5-year survival rate of 16% with a single agent checkpoint inhibitor, while better than historical data with chemotherapy (~4%), is far from being a home-run, illustrating what a dismal disease this is to treat.

One of the challenges that we are starting to see with checkpoint inhibitor cancer immunotherapy is immune escape or acquired resistance in some patients. They may have an objective or partial response, and then relapse and progress (acquired resistance), or they may not respond at all (primary resistance).

From our experience with targeted therapies, it should perhaps come as no surprise that cancers may evolve, adapt and seek to evade immune detection. There are also many inhibitory factors in the tumour microenvironment to overcome in order to enable an immune response.

At AACR17, Dr Brahmer kindly spoke to BSB about what researchers at Johns Hopkins have learnt about checkpoint inhibitor resistance in lung cancer so far. Her insights are both insightful and very useful when we consider what to watch out for at the forthcoming ASCO meeting.

This post is part of our on-going series of expert interviews from AACR17.

In the additional commentary, now that the ASCO17 abstract titles are publicly available, we’ve also highlighted a few that caught our attention.  This is the first in our series of previews of ASCO17. We’ll be rolling out more hybrid posts as we segue our coverage from AACR17 to ASCO17.

Washington DC – this is our final daily post from the 2017 annual meeting of the American Association for Cancer Research (AACR).

Starting on Monday we’ll be writing up expert interviews and providing commentary and analysis around some of the sessions we went to and the data we heard.

Tuesday at AACR17 was a day when the Corvus Pharmaceuticals stock dropped 50% following presentation of preliminary clinical data for their A2A receptor antagonist CPI-444.

It’s hard not to be disappointed when you see the waterfall plots skewed to the left and above the X axis, but we really don’t have enough data yet to determine whether CPI-444 on it’s own or in combination with atezolizumab may offer benefit to some cancer patients and if so, which ones.

The company have expanded the renal (RCC) and lung cohorts (NSCLC) in their initial trial, and they’ve told us to expect more data at ASCO17 in a few weeks time. Small cap biotech stocks can be a roller coaster when it comes to data presentations at major medical/scientific meetings.

What else caught our attention in the sessions we attended on Tuesday at #AACR17?

One of the frequently cited conceptual frameworks in Cancer Immunotherapy is the Cancer Immunity Cycle developed by Drs Dan Chen and Ira Mellman from Genentech.

Ira Mellman Dan Chen Authors of Cancer Immunity Cycle

Ira Mellman and Dan Chen

As we heard Dan and Ira tell us on the Novel Targets Podcast recorded last year at #AACR16, the cancer immunity cycle doesn’t include all the elements that we now know impact the immune system and whether someone will have an immune response. The microbiome is one example that readily comes to mind.

To address this, Chen and Mellman have now published the next installment in the series in Nature:

“Elements of Cancer Immunity and the cancer-immune setpoint.”

The review paper published last month incorporates the latest research into a different framework that looks at the factors that influence what they call the ‘cancer-immune setpoint.’

Anyone involved with cancer immunotherapy knows how fast moving and dynamic the field is, something they draw attention to:

“The pace of cancer immunotherapy clinical studies is such that they have outstripped our progress in understanding the underlying science. However, this situation has created the opportunity to combine emerging scientific and clinical insights in a synergistic fashion that… will also provide guidance for the identification of new targets… and the crafting of a framework for making decisions on a personalized basis.”

Conceptual frameworks such as those proposed by Chen and Mellman will be of increasing importance as we try to make sense of the tsunami of cancer immunotherapy clinical trial data, including combinations, that is coming our way over the next 18 months.

During my recent visit to San Francisco for ASCO GI, I had the great pleasure to catch up with Daniel S. Chen, MD PhD, (Global Head of Cancer Immunotherapy Development, Genentech/Roche) and talk about his latest thoughts on how we should think about cancer immunotherapy.

In writing these review papers he told me:

“We look at this as an opportunity to really think about the field, and try to conceptualize what is happening.”

We also discussed their collaboration with Kite Pharma, something of relevance to conferences this week as we head off to BMT Tandem and the ASCO-SITC meeting.

The end result was a day to remember, most significantly it was one where we heard data that will change the standard of care in front-line non-small cell lung cancer (NSCLC), with the expected approval of pembrolizumab (Keytruda) for patients whose tumors have a high expression of PD-L1 (50% or more).

We’re continuing our daily digest of highlights from sessions we attended at the 2016 European Society for Medical Oncology (ESMO) Congress here in Denmark.

The sun has not shone much here in Denmark during the Congress, the above photo of Nyhavn was taken just before the meeting started, but the data at ESMO16 has shone brightly with two more publications online in The New England Journal of Medicine to coincide with their presentation in Sunday’s Presidential Symposium:

Pembrolizumab versus Chemotherapy for PD-L1–Positive Non–Small-Cell Lung Cancer (NEJM link)

Nivolumab for Recurrent Squamous-Cell Carcinoma of the Head and Neck (NEJM link).

This mini-series of daily digests over the 4 days of the Congress is intended to give subscribers a finger on the pulse on some of the buzz and conversation…. and occasionally an alternative perspective. We’ll be writing more detailed posts as part of a post-conference series.

In this post, @MaverickNY offers her topline impressions of the lung cancer data presented in the Presidential Symposium, how this will change how some patients are treated, and the resulting impact on the lung cancer landscape. Cancer Immunotherapy continues to drive changes in clinical practice, and is doing so at a very remarkable pace.

While in Marseille for the scientific meeting to celebrate the 40th anniversary of the Centre d’Immunologie de Marseille-Luminy (CIML), I had the pleasure to interview Hervé Brailly PhD, the CEO of Innate Pharma, a leading biotech company in the Marseille Immunopôle.

dr-herve-brailly-innate-pharma-ceo

Innate Pharma (@InnatePharma) was founded in 1999 by six immunologists: Hervé Brailly, Eric Vivier, Marc Bonneville, Alessandro Moretta, Jean-Jacques Fournié and Francois Romagné.

Yesterday’s blog post on “Why Target the Innate Immune System? An interview with Eric Vivier” sets the scene for today’s post.

Innate Pharma, as the name suggests, has pioneered targeting the innate immune system. The company has leveraged the research undertaken at CIML by Professor Vivier and others in the field of innate immunity.

Innate is leading the way in immuno-oncology by targeting checkpoint receptors on natural killer (NK) cells. In 2011 Innate signed a licensing deal with Bristol-Myers Squibb for the development and potential commercialization of lirilumab.

In a recent financial report (link to Sept 8 press release) the company announced that several clinical trials would read-out in the forthcoming months.

Without disclosing any material non-public information, Dr Brailly kindly spoke with BSB and talked about his vision for Innate, what data readouts we are expecting, and the inflexion point the company is now at.

This post was updated on Feb 6, 2017 with the announcement that the EFFIKIR AML trial failed to meet it’s primary endpoint.

Eric Vivier, DVM PhD (@EricVivier1) is a leading French immunologist whose research has focused on understanding the innate immune system, and in particular, the role natural killer (NK) cells and innate lymphoid cells (ILC) play.

prof-eric-vivier

He is Director of the Centre d’Immunologie de Marseille-Luminy (CIML) and a Professor of Immunology at Aix-Marseille University.

In addition to his academic work, he also co-founded the biotech company Innate Pharma back in 1999. Through the company, he is actively involved in the translation of basic research into new cancer immunotherapy treatments.

New clinical data is eagerly expected for one of these, a first-in-class monoclonal antibody against KIR (lirilumab). It is in phase 2 clinical trials with Innate Pharma and Bristol Myers Squibb.

At the recent scientific meeting to celebrate 40 years of CIML (#CIML40), Professor Vivier kindly spoke to BSB about his research into innate immunity and the Marseille Immunopôle, for which he is also a co-founder.

It is an immunology cluster that brings together academic/clinical research with innovative biotech companies looking to bring new drugs and diagnostics to market.

This is the second post in our mini-series from the Marseille Immunopôle and CIML40. It also sets the scene for forthcoming posts on targeting the innate immune system, something you can expect to hear a lot more about in cancer immunotherapy.

Prof Fran Balkwill Barts Cancer InstituteWhen it comes to cancer immunotherapy drug development, one of the challenges is that we can’t accurately predict from preclinical mouse models what will happen in people. The result is a rush into the clinic to test in human subjects.

We do need better preclinical models, which is why it was interesting to hear recently on an episode of Health Check (BBC World Service) about a 3D tumour model that is being developed at Barts Cancer Institute.

Professor Fran Balkwill (pictured), who leads the Centre for Cancer and Inflammation, kindly spoke to BSB about the work she and colleagues are doing to model the tumour microenvironment (TME) in high-grade serous ovarian cancer.
