Posts tagged ‘ASCO 2016 annual meeting’

This week in our colorectal cancer mini-series we have covered the validation of Immunoscore as a tool for determining which patients have high T cells in their tuours and are therefore candidates for single agent immunotherapy (Link), as well as microsatellite instability (MSI) and mismatch-repair deficient tumours and how they can respond immunotherapy (Link).

What happens in the majority (95%) of patients, the microsatellite stable (MSS) disease who are mismatch-repair proficient though?  They don’t respond well to checkpoint blockade so how can we help them?

Dr Johanna Bendell ASCO 2016In Chicago, BSB interviewed Dr Johanna Bendell from the Sarah Cannon Research Institute in Nashville, Tennessee to find out more about what she and her colleagues have been doing and where they plan to go next.

We’ve been following the work of Dr Jérôme Galon, a French immunologist, on Immunoscore for a while now, and many readers will remember the last interview he kindly gave BSB from the European Cancer Conference in September [Link].

IMG_6454In 2015 the large global trial to validate Immunoscore as a biomarker was still ongoing, so if you want some background to this important concept, do check out Dr Galon’s interview as it’s well worth reading as a primer on immunosurveillance, the importance of immune cells – the type, density and location, as well as background on the Immunoscore test as a marker of outcome.

Since then, the group have also published some related data that both moves the field forward and offers a way to unify some important concepts in colorectal cancer.

In Chicago, the really good news was that the final results of a large global study involving nearly 4,000 patients were presented to a packed audience in the main hall where the plenary is held. It’s not often you see the gastrointestinal oral session allocated the prime time room over lung or breast cancers – the atmosphere was certainly electric with anticipation!

This week’s post ASCO mini series focuses on colorectal cancer, with a look at several important aspects of this disease as we learn more about the underlying biology, as well as how the immune system functions and how we can use that scientific knowledge to improve outcomes for patients, sometimes in a dramatic way.

Crowds of People at ASCO 2016

There has been much frustration on many fronts at the number of trials that do not see a relationship between PD-L1 expression and response. Some do, but many don’t. This has lead to quite a few investigators suggesting that the IHC assay may not be as useful as originally hoped, for predicting response to checkpoint blockade or selecting patients for therapy.

While we often do see a trend for more responders with higher levels of expression, the main issue is that PD-L1-negative patients can also see some responses, albeit at a lower rate.

There are many factors that can affect the measurement:

  • Fresh vs. archival tissue
  • Heterogeneity within the tumour
  • Tumour cells (TC) vs. immune cells (IC)
  • Different antibodies used for each assay
  • The dynamic nature of the tumour microenvironment – does timing of the biopsy matter?
  • Human error – a pathologist has to eyeball the IHC readouts and decide the level of staining intensity

And so on. These are just a few examples of the factors that can potentially affect the results, making it quite a challenging test to undertake. There is also time – does the level of expression vary temporally depending on which prior therapies are administered?

It would be easy to be disheartened by this, but fear not!

There were some impressive new data presented at ASCO that were not only intriguing, but also show us a way forward on how a multi-factorial approach could be used in different tumour types. By this I mean we might end up with different tests used in conjunction for several different cancers in order to a) predict responders and non-responders and b) better select patients for appropriate regimens or clinical trials.

It’s not going to be as easy as one size (or test) fits all.  Sometimes a more more sophisticated approach will be needed.  New data at ASCO gave us hints on what’s to come in this direction.

One of the exciting developments in metastatic urothelial carcers of late has been the emergence of checkpoint blockade with some very encouraging signs of durable clinical activity. Urothelial cancers comprise a group of urinary tract tumours including bladder, penile, ureter etc, although most trials tend to enroll bladder cancer patients, where there is a high unmet medical need.

This year alone has seen the FDA grant AstraZeneca with breakthrough therapy designation for durvalumab in February, while Genentech/Roche subsequently received approval for atezolizumab (Tecentriq) based on phase 2 data on May 18th.

To put these developments in context, the last FDA approval in metastatic urothelial carcinoma was almost 4 decades ago in 1978 for the chemotherapy cisplatin!

As is often the case in Pharmaland, once one company starts exploring a therapy in a given tumour type, others will quickly follow. Already we have several immunotherapy agents being evaluated in urothelial carcinoma both in early and metastatic disease, so what can we learn from the data presented at ASCO last week and where is the landscape going in the future?

Lung cancer, along with metastatic melanoma, has been very much to the forefront of attention in cancer immunotherapies with both nivolumab (Opdivo) and pembrolizumab (Keytruda) garnering approval as monotherapy from the FDA in second line treatment of NSCLC. A third molecule, atezolizumab (Tecentriq) has also been submitted to the authorities for this indication and a decision is expected soon.

While no one is in any doubt that the response rates with monotherapy are low (in the 20% range) and the majority of people do not respond, the important thing so far is that when they do, they appear to be very durable responses. People are living longer, much longer than the 2–3 months of incremental improvement we are used to seeing with chemotherapy or targeted therapies.

The race is now on to see how we can improve things for the 80% of people with lung cancer who don’t respond to single agent therapy:

  • What can we do to help them?
  • Which combinations look more encouraging?
  • Should we treat beyond progression?

To answer these questions, we interviewed Dr Stephen Liu and discussed his views on some of the cancer immunotherapy combination studies presented at ASCO last week.

Dr Stephen Liu

Dr Stephen Liu at ASCO 2016

Dr Liu is a lung cancer expert at the Lombardi Cancer Centre at Georgetown University, and is actively involved in numerous clinical trials, particularly in Developmental Therapeutics.

Georgetown’s founding principle is Cura Personalis, which translates as care of the whole person. It “suggests individualized attention to the needs of others, distinct respect for unique circumstances and concerns, and an appropriate appreciation for singular gifts and insights.”

Dr Liu embodies this ideal, advocating for his patients for access to the best research advances, including genomics and clinical trials of promising agents.  At ASCO, he kindly highlighted some of the important findings from Chicago and offered context on why they matter to the field.

He told us one combination was “potentially transformative” and could be “practice changing” in lung cancer with more data.

We have selected five key strategic trends that are emerging that will be critical to follow, understand, and even implement if you are on the coal-face of clinical research and new product development.

ASCO16 Chicago 5We aren’t talking about financial things such as cost toxicity, or even how doctors should be paid, but meaty scientific aspects that we need to watch out for. If we are going to improve on cancer research and R&D in the future, these issues will be important.

For companies and academic researchers alike, there is much to learn from the tsunami of data that hit this week if you have a keen interest in the field and a bent for making sense of patterns out of an amorphous mass of data.

Not paying attention to evolution in clinical development can mean the difference between being in the winners circle, on the outside looking in, or falling way behind your competitors. Playing catch up is never anyone’s idea of fun in this market – oncology moves at a lightning fast pace compared to many other therapy areas.

Chicago ArchitectureChicago – the ASCO 2016 annual meeting is in full swing. This is the third and last day of our rolling blog where we’re providing updates with top-line commentary throughout the data.

If interested, you can also check out the many updates from Day 1 and Day 2.

There’s a lot happening at ASCO today, including a presentation by Vice President Joe Biden later this morning. Allow extra time for security checks if you plan to listen to him in person, and I expect there’ll be delays to the hotel shuttle buses around Chicago as roads are closed to accommodate the VP’s motorcade.

Many people chose not to come to ASCO this year – but it’s turned out to be a great meeting. We’ve heard a lot of new data which are likely to have an impact on future clinical trial strategy, as companies look to bring new products to market in what is a competitive field, particularly in cancer immunotherapy. There are how many PD-1 checkpoints in development now?

A word of warning to the wise – not all these IO molecules are going to win – some are going to fail, some will be useful tools in various subsets and some are going to be new home runs.

Chicago RiverChicago – the annual meeting of the American Society for Clinical Oncology (Twitter #ASCO16) starts in earnest today, yesterday was primarily education sessions and a travel day for many.

Starting today and for tomorrow and Monday, we’ll be producing a daily rolling blog with top-line commentary around sessions we attend, experts we talk to and what captures our interest and attention at the meeting. It won’t be real-time, but schedule and wi-fi permitting, we’ll be providing updates throughout the day.

It really kills us to do a semi-live blog, but our subscribers love it – they tell us that even if they’re not at ASCO, they feel like they are with us following along remotely. We’ll of course be generating a series of posts with more in-depth coverage after the meeting when we’ve heard the data.

The 10 abstracts selected here are actually not in order of magnitude, preference or weight… with the lone exception #1, an incredible piece of work that was a decade in the making.



Few of these choices are in the press briefing, none are in the Plenary session – they’re often hidden gems that many will miss in the hurly burly of the data drop and noise.

They’re also 10 abstracts that I feel are worthy of highlighting with some additional commentary.

Some of the ideas here illustrate some intriguing trends that are emerging, others may have a big impact on the cancer immunotherapy space, either because of the novel concept idea, or because the data are very compelling, if you understand the science.

You can decide for yourselves – which ones would you pick and why?

After a long lull on the targeted therapies front – outside of EGFR T790M in lung cancer – this year’s ASCO has plenty to be cheerful about with new data across multiple tumour types.  We can’t cover them all here, but more will be discussed in the Daily Live Blogs starting on Saturday.

Which drugs are going to be in roaring back after a quiet period?  Which ones will be having a more muted meeting?

ASCO16 Chicago 4For those of you who are working in the targeting therapy world, take heart, there is a future beyond cancer immunotherapy; it is not the universal panacea and will likely not cure every cancer, at least for now.

There’s still a market opportunity for targeted therapies in cancer, and as we mentioned in yesterday’s ASCO Preview, there is also potential for the combination of targeted therapies with immunotherapies, so long as the combined toxicity is manageable and doesn’t outweigh the benefits.

In this post we’re looking at a selection of targeted therapies in a variety of tumour types. There’s a lot to choose from at ASCO this year.

Here’s a few we think are worth highlighting upfront.
