Is the emerging early stage myeloma landscape as bleak as Titan in Clydebank?

For years we have seen much of the therapeutic research in multiple myeloma concentrated on three main categories:

  • Proteasome inhibitors
  • IMiDs
  • Anti-CD38 antibodies

Then came a raft of anti- BCMA and GPRC5D targeted approaches in various forms, but what else should we be looking out for?

It turns out there’s quite a few contenders of interest – we cover some of them in our latest look at early stage compounds to watch out for…

Gaudi Cathedral, Barcelona

It seems oddly surreal of my photo editor to remind me that on this day in the past we were in Barcelona (right) for some conference or other and this year’s EORTC-NCI-AACR Molecular Targets meeting (aka the Triple in industry parlance) was cancelled in Spain in favour of a virtual meeting, thanks to the ongoing pandemic.

There is no doubt that thinking big in cancer research is vitally important, but sometimes we have to consider the difference between building cathedrals for the long-term rather than building simple walls as short-term fixes.

Here we consider some examples in the context of oncology drug development and also open the monthly October BSB mailbag…

We have two stories to share today from the EORTC-NCI-AACR Molecular Targets conference, which are posted separately owing to different embargo times.

The second posting later focuses exclusively on KRAS and Mirati’s turn in the spotlight.

Due to the embargo, it will not be available until 1545 hrs CET (1045 hrs ET) and will include some thought leader perspectives on the data.  I’ll add the link here in due course.

Developmental Therapeutics is often a cases of sunny days or stormy waters ahead…

Meanwhile, in the first post (below) we take a keen look at some of the new developmental therapeutics approaches coming through company pipelines.

Which ones shine might brightly and which ones lose their lustre?

As is often the case with early stage trials, translating rational science in preclinical setting doesn’t always translate well into the clinic when humans receive a therapy or particular combination of agents.

To this end, you might be surprised at how much PK/PD issues, half life, dosing/scheduling and other many other factors can severely impact the therapeutic window.

In this post, we look carefully at several targets we have been following preclinically for a while and finally initial clinical is either available or they are heading into the clinic – what can we learn from the presentations?

The annual ASCO-SITC meeting (#ImmunoOnc19) was held in San Francisco this year and has come a long way from the inaugural event we attended in Orlando.

Finding the signals amongst the noise

In the original 2017 event, I vividly recall as stirring presentation from Dr Limo Chen on targeting CD38 in solid tumours, last year we wrote an update on GU cancers including the STING pathway.

What’s in store from San Francisco and how do we go about finding key signals from the noise?

Over the next two posts I’m going to focus on new findings in various approaches that either look interesting and worth watching, or where there are lessons that can be learned for future developments.

This time around, some of the highlights surprised even me…

San Francisco

The first cancer conference of 2018 is now upon us and after enjoying last year’s event in San Francisco, I wanted to take some time to explore some key abstracts of interest at the ASCO GI meeting, which begins tomorrow.

This conference covers various updates on new developments in oesophageal, gastric, colon, pancreatic and colorectal cancers.

Are there any trials or new developments to get excited about at this year’s GI18 meeting?

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.

ASCO 2016 Posters 3

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?

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?

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.

View from ASCO annual meetingChicago – it’s “Plenary Sunday” at the 2016 annual meeting of the American Society for Clinical Oncology (ASCO).

Cancer immunotherapy has arrived at ASCO! Not so long ago cancer immunotherapy presentations were in small meeting rooms and had only a few attendees – at this meeting cancer immunotherapy data is being presented to thousands of attendees in large meetings rooms, including the B1 plenary hall. What a difference in the space of a few years!

Today at ASCO there are several noteworthy cancer immunotherapy presentations. We’ll be writing about them here on the blog during the day.

Part of the opportunity of coming to a meeting such as ASCO is the networking opportunities it affords.

While in Chicago I heard about a phase 3 trial from a global pharma company that failed to meet its primary endpoint last year, however, – to the best of my knowledge – there’s been no publication or presentation of the negative data that may help the field move forward. The investigators have been told “it’s a bust.”

Not to publish or present negative data is a disservice to the patients that enrolled on the trial. Many would have believed their participation would contribute to the advancement of science and medicine, and potentially benefit others.

Want to know what the trial is and the company involved? Subscribers can login to find more or you can purchase access to read more, along with our coverage of Sunday at ASCO 2016.

Update 12.30pm. Occasionally we decide something we talk about needs to be “open access” so we’ve published a short post. It is freely available to all. Turns out the negative data from BMS was mentioned in a July 23, 2015 financial results press release. Almost a year later, the negative data has still not been presented or published.
