Scaling the ramparts in Real Madrido

In our last ESMO23 Preview ahead of the live meeting starting on Friday, we highlight another eight targets to watch out for where there will be intriguing data dropping out from Madrid over the weekend.

More than just the data though, is consideration for the implications of the findings and how they can impact a particular tumour landscape.

One thing to note is just because a company highlights what they consider to be positive data doesn’t always mean it is actually so when you look carefully at the small print.

Not surprisingly there are a few examples of this genre at the forthcoming conference…

One of the many challenges in the oncology space is seeing the bigger picture of how companies evolve their early stage pipelines.

For some, it’s a bit like taking a walk in the forest and not being able to see the wood from the trees – the targets chosen are rarely random, especially those involving collaborations.  There’s a reason for pursuing a given approach, particularly i it is intended to be employed in combination with an existing, approved therapy.

There are many choices out there and even those with the deepest pockets can’t have everything, so often I’m fascinated by the selections that are taken and how they might fit in.

In our latest company review, we talked to a big pharma company active in the immunotherapy niche and sought to explore the early stage agents they are developing in the context of future doublet and triplet combinations.

Why are they doing what they’re doing and how might their approach be differentiated from others?

Hot or not? A saucy look at some oncology products in early development

One of the most common questions we receive heading into ASCO is what’s hot in in Developmental Therapeutics?

This is a really hard question to answer in any concrete fashion bearing in mind we have only titles and no data to speak of at this stage.

What we can do is highlight some intriguing topics, targets, or molecules we have been following and put their potential in the context of recently published data or announcements.

While it’s easy to over react to skimpy top line announcements from companies, sometimes the early warning signs (positive or negative) were visible a couple of years ago because the devil, as always is in the finer details.

Here we take another five new product developments and put them through their paces with some discussion on the broader context from either BSB or experts we have interviewed on the various topics…

It still feels really weird not to be heading off to Chicago O’Hare in a few weeks

Every year at ASCO we take a quick look at various trials which jump out from the first pass of the data once the abstracts become available then follow up with more in-depth previews later.

There are some winners and losers in this mix, as well as some hidden gems and informative analyses to think about.

So without further ado – what stood out this year for better or worse?

The start of a New Year is a good time to take stock of where we’ve come from and where we’re going in the fast-paced world of oncology new product development.

Upregulation doesn’t always mean a protein is a valid target, but in some cases it just might…

In this latest post, we’re revisiting T cell immunoglobulin and mucin domain-containing protein 3 – or TIM-3 in short – and taking a closer look at the evolving competitive landscape in this niche.

One company targeting it is Novartis, who have an anti-TIM–3 antibody MBG453 in development. In this post we have an expert interview with a scientist who is a pioneer in the emerging field of TIM-3 biology.

There’s also a review of some of the recent important scientific papers on TIM-3 biology, as well as commentary on data presented at ASH19 that we expect may feature in presentations at JPM20 next week, not to mention be the focus of future interim updates should the data turn out to show some promise in certain settings.

If you have an interest in targeting novel immune checkpoints and want to find out more about where the field is at with TIM-3, then this post is for you.

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…

Following the success of anti-CTLA4 and PD(L)1 therapies over the last five years or so, there is much time and attention being focused on addressing a key question, namely – what’s the next viable checkpoint target?

There are quite a few possibilities emerging, although to be fair, some of them will no doubt go by the wayside over the next year or two.  There has already been quite a bit of attrition since 2015/16.  Figuring out which ones will be a target versus being a useful marker is also an important aspect of new product development.

Competition is a fine thing – as long as they’re going in the direction you want to go.

For most of our ASCO coverage over the last few years we have tended to include a variety of approaches in the pre-conference Preview series that can run from a tumour type, a up and coming modality, an emerging target, and various other ways of looking at or making sense of the sea of data.

Here, we take a look at an IO target that is receiving much interest and explore what we know and where this might be headed… and ask whether the early promise is living up to the billing in practice?

SITC Phase 1 Review Part 1 – It’s time for a two-part mini-series on recent phase 1 clinical trials and how to interpret the findings.

Are we at a crosswords with IO combos?

As a former new products development professional, this is something that I’m particularly enthusiastic about.

While it is fascinating to see other people’s reactions to early oncology trials, these should often be taken with a very large pinch of salt, in my view.

In Part 1, it’s time to take a step back and understand not only what companies are doing, but also how they set the trials up and what they are looking for. We highlight some examples of data readouts to illustrate the points.

In Part 2 on Monday we take a rock around the clock at some of the other recent phase 1 readouts and explain what we can learn from what was presented. The devil is often in the small details that many observers miss at first glance.

Summer time always seems a good opportunity to explore new cancer targets or approaches on BSB and we’ve covered quite a few interesting concepts over the last couple of years.

ASCO18 Gems from the Poster Halls

This particular approach is an up and coming immuno-oncology target that I noticed is quietly gaining increased interest amongst pharma companies and not all the usual players either.

Consider typing in [target] + cancer in PubMed…

What I got was one single paper in 2000, nothing until 2006 (two more papers), then one to four new ones a year dribbled out until 2014 when nine appeared, followed by a big jump to 17 in 2015, over 20 the following year, then finally more than 30 last year.

At the current rate there will likely be 40–50 such articles in 2018, making for a typical sigmoid growth rate of interest.  Boom!

Clinical trials (montherapy and combinations) are already in early phase studies in the clinic, so this is a good time to take stock and look at progress to date. It also makes for interesting reading when put together as a whole!

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?
