Chicago – 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.

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).
In 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.

It’s the end of April and just in time for two important things here on BSB…
A) Season 2 of our Novel Targets podcast has now kicked off!
The first show (sponsored by Genentech) explores the cancer immunity cycle (CIC), how it can help see the bigger picture and how this framework can be used to help figure out what areas are missing when patients don’t respond to immunotherapy.
There are also predictions about what we will see coming up in the next year – will the crystal ball be accurate – or not?
Crank up the Sonos, grab a coffee, pen and paper – you’ll find the latest podcast show here (Link), which is open access for anyone who wants to listen.
B) Reader Q&A Mailbag: we tackle your latest tough questions that are top of mind and offer insights on the hot topics people want to know about.
We have a broad range of topics to cover today including:
- The battle for PD-1 sales
- What are the IO bottlenecks where we can expect to see new research focus
- Sanofi-Medivation bid
- AbbVie snapping up StemcentRx

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

The 2015 annual meeting of the American Society of Hematology (ASH) (Twitter #ASH15) in Orlando has a bumper crop of interesting data.
ASH is one of the my favourite meetings on our conference calendar. I’ve been attending for many years, starting with when I was a commercial account manager for Hematology, Immunology, Transplantation and Oncology in the UK, then at Novartis in the US, when I was part of the team that brought Gleevec to market.
Hematologists make for an interesting group of people to talk to! They are very focused on the science behind a disease and how translational research can move the needle forward and generate better outcomes for their patients.
As part of our continuing preview of #ASH15, I’ve taken a quick look at the late-breaking abstracts that were released today. We will have more in-depth coverage after we’ve heard the data presented in the 7.30-9.30 am session on Tuesday December 8.

If you’re not already a subscriber, but what to know “What’s hot at ASH15?” then you should purchase access. Additional ASH previews are already planned. By the time you’ve read them, you should “hit the ground running” in Orlando.
As Warren Buffett famously said, “Price is what you pay. Value is what you get.” I couldnt agree more. We have subscribers who just purchase our ASH coverage every year, so do “check it out“ if you haven’t done so already.
We have followed the roller coaster development of the Bcl2 inhibitor, venetoclax (ABT–199/GDC–0199), for several years now. There have been some lowlights along the way, but lately, things have been much rosier for AbbVie and Genentech as a more sensible dosing and patient management approach has been paying off.
Recently at ASCO and ASH, we have seen encouraging new data emerge in leukemia (AML and CLL), lymhomas (NHL), and even multiple myeloma.
New data has now emerged that looks quite interesting in another blood disorder. Today, we took a look at the data and also the potential implications for venetoclax’s development program.

Last month’s Biotech Strategy mailbag – where we answer questions from subscribers – turned out to be rather controversial with strong feelings running in several camps on Puma Biotech’s neratinib in breast cancer.
This time around we have a bunch of questions on completely different topics and compounds to cover:
- BRAF plus MEK and/or immunotherapy in BRAFV600 metastatic melanoma
- Immunogen’s IMGN853 – now known as mirvetuximab soravtansine – in platinum resistant ovarian cancer
- AbbVie/Genentech’s ABT–199/GDC–0199 venetoclax

It’s time to answer some more subscriber questions. Several readers wrote in and asked about the anti-PD1 checkpoint data that was presented at the recent American Society of Hematology (ASH) meeting in classic Hodgkin’s lymphoma (cHL):
What did we think of it?
Well, for starters it was one of our highlights of the ASH 2014 conference (see quick write-up, open access), with an impressive 87% response rate for nivolumab in refractory cHL. Many of these patients had failed both autologous stem cell transplant and brentuximab (Adcetris), for which FDA granted breakthrough therapy designation.
Overall, I agreed with Ron Levy (Stanford) when he noted in the packed Special Session on Checkpoint inhibitors in Hematology that there were only 4 or 5 abstracts to actually discuss (he didn’t spend much time on the preliminary data) and that the results are still very early without seeing how good the durability will be.
As he observed in the session, which was standing room only, figuring out how best to integrate these new agents into clinical practice with other successful approaches will be most interesting.
That said, there are some new data that have emerged since ASH that are worthy of discussion in terms of potential future directions and how they could impact the checkpoint landscape in both hematologic malignancies and even solid tumours.
This is part of our ongoing immuno-oncology series on how we can manipulate T cells in creative ways to kill the cancer cells. The findings discussed in this article are completely new and have not been discussed here before.

A couple of years ago we had a lot of fun here on BSB following the progress of ibrutinib (Imbruvica), obinutuzumab (Gazyva), and idelalisib (Zydelig) in CLL and indolent NHL. It seemed back then that the stunning trio were the hot topics for some time at ASCO and ASH meetings. Exciting times! All three target different entities (BTK, anti-CD20 and PI3K-delta) and made it past the tape to market, with Gazyva leading, Imbruvica a close second and Zydelig a slightly more distant third. I was reminded of the race again over the last week or so as the 4Q earnings were announced, with Pharmacyclics reporting almost $500M for Imbruvica last year and estimating sales to hit $1B in 2015. In contrast, Zydelig revenues for 2014 were $23M, reflective of their much later market entry in the US.
Still, that was a pretty impressive set of drugs all in development at the same time.
Two other agents we also reported on regularly were Infinity’s IPI-145, a PI3K delta-gamma inhibitor, and ABT-199/GDC-0199 (now known as venetoclax). I haven’t heard much about the former of late, but after a few missteps, the next big question to consider is whether venetoclax is coming back strongly or destined for dog drug heaven?

Previously, we discussed the role of new agents being developed for aggressive non-Hodgkins lymphoma (NHL) with Dr Nancy Valente of Genentech, particularly how their antibody drug conjugates (ADCs) could have a potential role to play in revolutionizing treatment for patients with an otherwise poor prognosis.
The second half of the interview from ASCO 2014 focuses on more indolent disease, namely chronic lymphocytic leukemia (CLL) and the role of their novel therapeutics obinutuzumab (Gazyva) and ABT–199/GDC–0199.
We’ve heard a lot of positive data about the anti-CD20 monoclonal antibody, obinutuzumab, but the Bcl2 inhibitor undergoing co-development with AbbVie has had a bit of a chequered history to date. There is no doubt that ABT–199/GDC-0199 is highly potent, while lacking the severe myelosuppressive effects (thrombocytopenia) of its predecessor, navitoclax — which can be both a blessing and a curse — as the phase I single agent investigators discovered recently when severe tumour lysis lead to two sudden patient deaths.
It is important to address these issues expeditiously in a safe and rational way to ensure patient safety for those who enroll in both current and future trials. This is a critical issue we discussed at length with Dr Valente and how the company has been handling it.
At the AACR Molecular Targets meeting last November, many readers will remember that we learned about Genentech’s research plans for combinations with GDC–0199 in CLL and NHL in an interview with one of the scientists for that program, Dr Deepak Sampath.
Today, it’s time to look at where and how this exciting agent might impact CLL. Obviously, both CLL and NHL have commonalties and overlap, since they are both B cell disorders, so often what works in one disease often works well in the other too, as rituximab has clearly demonstrated.
