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

Much of the focus in multiple myeloma over the last decade has focused on two key drug classes – proteasome inhibitors and IMiDs – with some recent approvals for monoclonal antibodies targeting key proteins on the surface of malignant myeloma cells such as CD38.

#ASH16 in San Diego

Combinations of these core therapies have lead to a noticeable improvement in outcomes for people living with the disease – from 3-4 years over a decade ago to now approaching 10 years post diagnosis.

If we want to continuously beat the status quo and improve on the chronicity, however, it is likely that several things will need to happen:

  • Better understand mechanisms of resistance that induce relapse
  • Develop predictive biomarkers of response
  • Identify novel therapeutic targets

Here. we focus on the latest preclinical findings that were recently presented at the American Society of Hematology (ASH) in San Diego and explore where the future might be headed in this disease.

Post 2016 US Election, we move on and get back to business with an in-depth review of some new science and clinical data.

ash-2015Yes, it’s time for another Bushidō – “Way of the Warrior” – guide to the key ASH abstracts!

Here we focus on acute myeloid leukemia (AML), a difficult and challenging disease to treat with a high unmet medical need for new effective therapies.

In this Preview we look at key companies in the AML space, as well as a look at what’s happening in classic targets and also some new ones that are receiving notable attention, both preclinically and also in the clinic.

The BET Bromodomain market is a meaty epigenetics topic we have followed for several years now, including a look at the space back in 2013 on the old Pharma Strategy Blog (Link). The last update on this was ironically at AACR last year when we discussed MYC and bromodomains (Link).

Nawlins Mardi GrasIn a remarkable tale of two cities in real life, two companies we discussed in those posts – Constellation Pharma and Tensha Therapeutics – have had markedly different fortunes since then. Roche decided to end their collaboration with the former and went on to acquire the latter instead.

Since we first wrote about bromodomains and BET inhibitors, the niche has exploded in a wildly stunning way… More drugs in the pipeline, more tumour targets being explored, and even novel combinations being evaluated preclinically for synergistic or additive effects. Even I was surprised by how competitive this niche has become based on the offerings at AACR this year.

With all the wealth of new data at the AACR annual meeting and also some other recent presentations I’ve attended elsewhere, it’s time for a more in-depth look at the BET/Bromodomain landscape.

Who are the new players, which tumour targets are now being evaluated, which combinations might be useful?

A word to the wise – this is neither a nerdy science post nor a comprehensive literature review – instead we take a look at the emerging landscape from a new product development perspective.

Science has been absolutely critical to success in all of the cancer therapeutics from targeted therapies to immunotherapies that have emerged in the last decade.

It really doesn’t matter whether you come from a marketing and commercial organisation or the investment community – if you want to make great decisions, you need to understand the basics of the science underpinning the R&D, where the strengths and weaknesses are. The alternative is play Roulette and put everything on Black 11 as a euphemism for whichever company/product/target you have an interest in.

This week certainly turned out to be a defining tale of two drugs with a chequered history…

Lion DancersFirst off, the FDA approved AbbVie/Genentech’s venetoclax, now known as Venclexta, in a subset of CLL patients with 17p deletions. These patients have a historically poor prognosis and the approval goes some way to addressing the high unmet medical need.

Secondly, another biotech company, Clovis Oncology, got slammed by ODAC with a 12-1 vote to wait for phase 3 data from the TIGER-3 trial for rociletinib to better determine the efficacy:safety benefit profile.

For a long while it seemed that AbbVie had nothing but toil and trouble over the tumour lysis syndrome (TLS) issues giving them some significant challenges to overcome, while Clovis were one of the new darlings of Wall Street.

In the final dash to the market, the tables were turned almost at the 11th hour and fortunes stunningly reversed.  Yet a mere eighteen months ago, few industry watchers would have predicted the difference in outcomes.

In our latest AACR Preview series, we take a look at Bcl2 inhibition and where some of the emerging opportunities might lie based on new preclinical research that is being presented here in New Orleans this weekend.  It makes for interesting reading.

While one tiger is licking its wounds, another is smacking it chops at what the future might hold for new combination approaches; how the tails have literally turned.

In today’s post, it’s time to address a bunch of questions we’ve received over the last few weeks from subscribers about the latest and – not so greatest – in cancer research.

Chicago City View

ASCO 2015 Chicago

Sometimes these queries are fairly straightforward to answer, other times requires some sleuthing and hunting down thought leaders for some additional context and insights… For obvious reasons, these folks are best caught in person at cancer conferences such as AACR and ASCO.  The feedback isn’t always sparkly and positive though, it can also be gloom and doom, just like the inclement weather!

So here goes, questions on the following are covered in the article below:

  • Neratinib
  • Bavituximab
  • Gilead
  • Enzalutamide
  • MDSCs
