Commentary on Science, Innovation & New Products with a focus on Oncology, Hematology & Cancer Immunotherapy

Posts tagged ‘OX40’

We have come a long way from our last discussion about the bispecific antibody landscape going into the ASH20 meeting, with the current update on the field barely including any of those established agents, such is the pace of progress in less than a year!

Of course, part of difference lies in the old liquid versus solid tumour settings, where different tools or targets are needed for each one.

The good news is there are a lot of new players to look at, both private and public, emerging biotech and established pharma companies.

Some of the evolving trends which emerged from our latest analysis surprised even the seasoned observers at BSB, which is no bad thing at all.

So what’s in store from our latest in-depth review going into SITC 2021?

It is becoming increasing obvious in these challenging times as the pandemic spreads globally that no corner of the earth (except perhaps the Antartica) is being left untouched.  As lockdowns begin or continue depending the phase the spread is at, this also has numerous implications for clinical trials, both academic and company funded studies alike.

Which direction should we be considering for early anti-cancer therapeutics?

One of the broader effects of the coronavirus pandemic likely means we won’t see much new data on many of the clinical trials after the currently scheduled presentations for AACR, ASCO, ESMO and ASH for a while yet, perhaps well in to 2021, which in turn is a strong reminder if we want to see how much progress is being made then we need to look at what data is available now.

I can well imagine many folks are already completely Zoomed or WebExed out from constant online meetings dealing with the implications of the pandemic on research and clinical development, as well as what happens to new and existing trials, so the idea of listening to two days of a virtual meeting on top is probably a bit daunting for the time-challenged observers amongst you.

AACR’s virtual meeting is a wonderful opportunity for smart folks to take some careful snapshots of where we are now, and how some of the early pipeline agents are shaping up.

The good news is we while your online internal meetings continue apace, we will be posting many reviews, summaries, discussion and analysis of the data here on BSB, hopefully sparing many of the additional stress in busy times. We plan to make the process of analysis and commentary relatively easy so you can follow along with us.

For reference, you can access all of our ongoing AACR20 conference coverage here. Future posts will also be added to this magazine page as they are posted.

In our fourth AACR Preview series, we take a keen look at some additional early products in development of interest, as we continue our updates on the never ending oncology R&D journey.

We highlight 10 emerging agents in early stage development to watch out for…some are new and others we previously reviewed preclinically and have moved along in their R&D journey into the clinic, with good and bad results to think about.

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.

National Harbor, MD – Day 2 of #SITC17 brought some interesting highlights on a number of fronts, not all of which may be apparent at present, but there are a few readouts that will have a broader impact going forward.

SITC 2017 Stars?

As we move into an era where we see more combinations evolve in immuno-onology, things are likely to get more confusing rather than less so and it could well be another 3-5 years before things truly settle down and more concrete trends emerge.

Here, we reviewed 10 different areas of interest with a strong clinical relevance and explored the topics further.

Please note that some of these will also have follow-on posts with thought leader interviews and related poster reviews.

Dr Bernie Fox (@BernardAFox) is a man on a mission to #FinishCancer, a Twitter hashtag he uses to reflect his vision.

A cancer immunotherapy rockstar, Bernard A Fox, PhD, is the Harder Family Endowed Chair for Cancer Research at Providence Center Center and Chief of the Laboratory of Molecular and Tumor Immunology at the Earle A. Chiles Research Institute in Portland, Oregon.

Fox is also a past president of the Society for Immunotherapy of Cancer (SITC) and CEO of UbiVac, a biotechnology company focused on therapeutic cancer vaccines.

Readers of the Blog and Novel Targets Podcast listeners will recall we had the privilege to interview Dr Fox back at the American Association for Cancer Research (AACR) annual meeting in New Orleans in 2016: “AACR Cancer Immunotherapy Insights from Dr Bernard Fox.”

Fast forward 18 months… it is now time for a detailed update on this issue, as a few interesting events have since come to light in this niche with Genentech/Roche abandoning development of their OX40 agonist, coupled with several new publications from different labs suggesting that concurrent administration of an anti-OX40 antibody with an anti-PD1 antibody attenuated the effect of anti-OX40 and resulted in poor treatment outcomes in mouse models.

Dr Fox kindly spoke to Biotech Strategy Blog about some of the key learnings from this research, where he sees the future potential for OX40, and what his vision for cancer immunotherapy is.

Here’s a short clip from the fireside chat…

 

He’s definitely a man on a mission to #FinishCancer!

Over the years we’ve interviewed folks from numerous pharma and biotech companies here on BSB, including those with targeted therapies (small and large), as well as immunotherapies.

Some companies have small pipelines and may be forced by circumstances to explore what they have or seek collaborations with bigger partners.

For big pharmas with large pockets plus broad and deeper pipelines, the challenge is quite different – how do you prioritise potential combinations and tumour targets given it is impossible to evaluate them all in the clinic? How do you create differential advantage and value when you’re relatively later to market compared to your competitors?

In the BSB spotlight this week we have two researchers in clinical development and R&D from the same company, who happen to have both elements in their pipeline in areas of high competition.

Part one of our latest mini-series explores the IO side of the business as we look ‘Through the Keyhole’ at what’s going on in terms of biomarkers, monotherapy trials, combination studies (both IO-IO and IO-targeted) and what to expect in the near-term future later this year. It’s a wide ranging, candid, and fascinating discussion that highlights a lot of potential in terms of what could happen with a large pipeline.

In all, it makes for rather interesting reading and certainly changed how I perceived the company’s efforts in the IO sphere (for the better, I might add).  So what’s fascinating about their approach and what can we learn from their progress to date?

We’ve been saying for a while that 2017 and onwards would be when we start to see a few IO combination trials start to shake out. Interestingly, that process seems to have already started, if recent news is any thing to go by.

With this in mind, the annual meeting of the American Association for Cancer Research (AACR) coming up this weekend gives us a timely moment to explore combinations that are looking interesting… or not.

In the last of our AACR 2017 Conference Previews, we take a look at what to expect on this year’s program in the IO and Checkpoint arena. In short, it’s quite a lot and not without some controversy either!

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.

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.
