After a couple of years in the doldrums with a bunch of negative phase 3 readouts, I thought this was a good opportunity to sit back and reflect on the next tranche of targets and see what we can learn about them.

The answers were quite surprising when you look at the group as a whole because not everything is about the PD(L)1 – CTLA4 axis, thank goodness.

In the latest preview we explore five different categories and highlight mostly early and novel developments coming along from early stage biotech companies, which may be of interest to our eager readers..

Mononclonal and bispecific antibodies in the immuno-oncology space have certainly had a bit of a roller coaster ride over the last couple of years with various safety concerns including cytokine release syndrome (CRS) and even fatalities coming to the fore following clinical holds on various compounds across several quite different compounds.

As companies work their way through those issues with FDA and other Health Authorities, can we also learn from our previous experiences with checkpoint blockade, immune agonists and other IO targets in order to develop safer products?

One thing has become clear and that’s how important particular aspects of the engineered molecules can make an impact in terms of both safety and efficacy. There are, after all, quite a few factors that can be manipulated or changed to impact performance, much as the design arrangement and composition of various components into a unified whole is crucial to Formula Once racing cars.

In our second part of the bispecific mini-series, we head over to Europe and interview the CSO of a leading company in the IO bispecific space to learn more about these design features and the potential benefits they might induce.

It makes for rather interesting reading when we consider the next wave of IO clinical trials…

Mainz, Germany: We’re back for Day 2 highlights from the 2019 Association for Cancer Immunotherapy (CIMT) annual meeting with a look at some insights emerging from some academic and industry talks, as well as gems emerging from the poster halls.

Much attention is focused on cancer immunotherapy clinical data, yet it’s also important to watch out for new developments.

These can take many different forms such as what are companies doing to meet those challenges with novel therapeutics, as well as understanding more detail about immune mechanisms, including evasion and escape as well as defining phenotypes based on different immune cell populations.

As we head into ASCO, let’s not forget that there’s some important learnings to be had elsewhere in the world before we get there…

The keynote address at the 2018 CRI CIMT EATI AACR International Cancer Immunotherapy Conference in New York last month was given by Ignacio Melero (Pamplona). Professor Melero gave an engaging and informative presentation entitled, “The immunotherapy faces of Interleukin–8 and CD137.” He also had a related talk on “4–1BB and Metabolism” at the Society for Immunotherapy of Cancer (SITC) meeting this weekend.

Pinning down new opportunities in IL-8 and 4-1BB

The late and sadly missed, Dr Holbrook Kohrt (Stanford), worked closely with Prof Melero on targeting CD137 or 4–1BB, as it’s more commonly known.

Regular readers may recall our interview wth Dr Kohrt back at Immunology 2015 in New Orleans (Link).

Professor Melero kindly spoke to BSB at SITC 2018 and shared his thoughts on where we are three years on and where his research is currently focused in relation to cytokines, and in particular, IL–8.

Hans Bishop, Juno

After a rocky 2016 for Juno with JCAR015 and the trial that imploded unexpectedly and badly, the CEO Hans Bishop quietly announced that announced that ROCKET has been abandoned:

“2016 was a year of progress and learning for Juno and the cancer immunotherapy field. We continue to experience encouraging signs of clinical benefit in our trial addressing NHL, but we also recognize the unfortunate and unexpected toxicity we saw in our trial addressing ALL with JCAR015. We have decided not to move forward with the ROCKET trial or JCAR015 at this time.”

A strange year of hubris attracting nemesis might be another way of describing the events for some observers.

We covered the Juno roller coaster and events in July and December 2016 for those who want to catch up on the full history of this unfortunate and ongoing debacle:

Where does the latest Juno news leave things and what can we expect going forward?

As we move from monotherapies to combinations in the immuno-oncology space, we start to see some intriguing ideas being explored from additional checkpoints to vaccines to neoantigens to immune agonists to oncolytic viruses. There are numerous ways to evaluate how to boost or jumpstart more immune cells upfront in the hope of seeing better efficacy.

One way to do this is to better understand the tumour microenvironment.

If we know what’s wrong under the hood, we might be better able to make the immune system get going… more gas, faulty starter motor, dead battery, loose wire, broken fan belt? All these things and more might be a problem so you can see that diagnosing the issue up from from basic and translational work might be instructive for clinical trials.

If you don’t know what problem you’re trying to fix or repair then you might as well be throwing mud at the wall. Just as we don’t expect a car mechanic to suggest changing the battery or starter-motor without first diagnosing the issue, so understanding the tumour microenvironment in each different cancer or disease might also be a helpful strategy.

At the recent American Society of Hematology annual meeting (#ASH16), there was a fascinating sceintifc workshop that focused on this very concept – what’s going on under the hood and how do we go about fixing it?

Here we explore these ideas via an interview with a thought leader and specialist in the field. What he had to say was very interesting and candid indeed.

After regularly reporting here at BSB on several readouts in terms of antibodies and CARs since ASH last year, it’s reasonable to conclude now that there has been growing interest in BCMA–APRIL as a target in multiple myeloma (MM). The CAR T cell therapies have generally focused on BCMA or BCMA-TACI as a target, while antibody approaches such as Aduro’s, BION–1301, target APRIL.

These new therapies have all been either preclinical in nature or preliminary phase 1 studies in a very limited number of patients, meaning that the best we can characterise them is that old reliable chestnut, ‘promising but early’… to do otherwise would be rather extravagant and hopeful at best.

Given the data from several CAR T cell therapy studies were being presented at two meetings on two separate continents only a few days apart, it makes sense to review them as a whole.

It’s therefore time for a detailed update, including a review of the differences in the key studies, a look at where we are now, as well as tips on what to look for going forward.

Despite remarkable results with cancer immunotherapy to date, we do need to keep out feet on the ground and remember that response rates are relatively low to modest (10–30%) and the majority of patients do not respond or see a benefit with these approaches.

As we start moving beyond checkpoint monotherapy, the realisation has fast hit many researchers and companies that we really don’t know as much about the tumour microenvironment (TME) as we would like.

No doubt we will learn a lot more about it from the combinatory approaches, but be aware that this also means higher risk associated with such developments – we will likely see a lot of failures – and hopefully, some successes too.

This is where the little biotech companies have an opportunity to shine… they may have some intriguing IO compounds in development but not an anti-PD1/L1 backbone, meaning they can collaborate with a big pharma company to explore novel combinations in small phase 1/2 trials to determine what works or not. This is much lower risk (and R&D costs) for both parties and we get to see more quickly where things shake out.

At the annual Society for Immunotherapy of Cancer (SITC) meeting last week, there was a whole day devoted to New Immunotherapy Drug Development.  

Some of these agents look worthy of watching out for and following their progress.  A variety of data in different targets and MOA were presented from big and small companies alike.  We selected a few of the promising ones for further review and discussion.

We’ve come a long way over the last two years in the oncology market, with several novel approaches approved, numerous major phase 3 trials evolving and a huge turnaround for many companies in terms of early pipeline activity.

Unfortunately, this also means that the tendency of lemming activity also increases in the rush to copy everyone else and not be left behind.  Just a couple of years ago, some industry friends grumbled that there were over 20 checkpoint inhibitors chasing them in development; they may be surprised to know that now there are nearly 70!  This is both unprecedented and unsustainable, and yet it’s also a function of the perceived success these agents have had on the cancer R&D landscape to date.  Everyone wants one for fear of being left behind… except that many are indeed way behind already.

You can imagine the tall guy on the left of the picture looking at his watch and wondering, “Ah so many new posters, so little time!”

Meanwhile, as the rate of approved cancer therapies increases, so does the inexorable march in terms of hyper-aggressive basket pricing.  I would argue that at some point, it no longer acceptable or even conscionable to change a premium or even market rate for drugs that give an incremental improvement of a mere 2 months of extra life.

Equally, one thing that many industry observers and the media love to do, and wrongly in my view, is to compare the individual drug prices on an annualized basis.  This is silly for several reasons:

  1. So far, not all patients are treated for a full year
  2. If patients are treated until progression and that happens early, then therapy is stopped
  3. What people should be looking at is the average treatment cost based on the length of therapy – some people will receive a few months and some much more than that
  4. What’s the true cost of a cure or remission to a patient and their family?
  5. How do we quantify the impact of the long lasting durable remissions?

These questions will become increasingly important as we see a more aggregated therapy approach emerge over the next few years.

By this, I mean that we are now going beyond monotherapy and even combinations; those trials have already long started and are the low hanging fruit that has been rapidly snapped up by the early players, as we eagerly wait for their data readouts.

If you have new agents coming-out of preclinical and into phase 1 development over the next year, there are a number of important questions to consider:

  • What are you going to do and where do you start?
  • How do you gain an edge when coming from (way) behind?
  • How do you develop unique positioning that could sustain your molecule in a sea of similar competitors?
  • Is it realistic to expect the 17th and 50th checkpoint to have equivalent efficacy as what went on before and will all of these seriously make it to market?

You can see now why even the FDA’s Dr Richard Pazdur was moved to grumble about the surfeit of me-toos here and company expectations that the FDA should consider them – it’s on a massive scale that we haven’t seen before.  For once I agree and empathize with him over that dilemma, it’s madness to think they will all be as good as pembrolizumab or nivolumab.

What we are starting to see emerge now is a surprising synthesis of ideas and a merging of disparate approaches. How will this affect oncology R&D over the next 1–5 years?

A couple of smart readers wrote in asking about these emerging trends, what have we identified so far, and where do we see the oncology space going in the near to medium term future. Now that AACR and ASCO are behind us, what can we learn about the new developments and where they all fit in the oncology landscape strategically?

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.
