HMS VictoryThe dog days of summer are usually quiet on the Pharmaland front, although this year has been a bit of an exception, being notable for a batch of deals being completed and announced already.

The cell therapy space is one area that has courted both controversy and new collaborations, for example. Nary a week seems to pass without something appearing in the news! This has proven pretty interesting for a number of subscribers, who write in asking plenty of astute questions.

Today’s questions from BSB readers therefore encompass allogeneic cell therapies and what’s going on in that fast moving dynamic space.  Not all of the announcements may be what they seem though, and some are much more riskier than others.

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.

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.

For years we’ve followed the trials and tribulations of targeted therapies seeing many approved and quite a few disappear forlornly (and officially) off to dog drug heaven. Many more sit in no-man’s land as companies eagerly wait in a holding pattern for other trial readouts in different tumour types. Sadly, sometimes these studies don’t generate enough compelling data either. With so much competition about, there are no shortcuts or low-hanging fruit in biotech or cancer drug development any more.

En route to Chicago and ASCO!

Then along came antibody drug conjugates (ADCs), with some encouraging results in a range of cancers in both solid tumours and hematologic malignancies that lead to the approval of several new therapies.

After that, the next big advance was immunotherapies, specifically checkpoint blockade, with encouraging single agent activity in melanoma, lung, and even urothelial bladder cancer. We’ve also seen the promise fo combining two different checkpoints such as nivolumab and ipilimumab together in metastatic melanoma, albeit with an increase in toxicities.

This is all very well and good, although the challenge remains that the majority of patients either respond to therapy and relapse, or do not respond at all, depending on the circumstances, the tumour type and the regimen. We still have a long way to go in moving the needle and creating a new paradigm shift on a broad scale.

So what happens when we start to combine modalities – such as targeted therapies with immunotherapies?

Uh-oh, I hear the distant cries of disagreement erupt…

  • Remember vemurafenib plus ipilimumab in metastatic melanoma was scuppered by severe hepatitis?
  • What about osimertinib plus durvalumab in NSCLC and the increased incidence of ILD?

Both of these statements are true, and yet… we should not assume that all mixed therapy combination approaches are doomed on the basis of a mere n of 2. What happens if some are synergistic or additive? What happens of there are hidden gems that teach us new ways of doing things rather than doing the same old thing just because it’s always been done that way?

With this in mind, I’d like to open the door on our first ASCO 2016 Preview series with a look at novel combination approaches in development that caught my eye.

What are the early hints and signals that we can learn from the data? Which companies are evaluating imaginative new ideas that may turn the tables on traditional thinking?  The ideas discussed here may well surprise a few people.

We’re continuing our countdown to the 2016 AACR annual meeting in New Orleans with a look at anti TIM-3 and LAG-3 inhibitory checkpoints and highlighting some of the companies with noteworthy abstracts.

In case you missed it, yesterday AACR announced that Vice President Biden will be delivering remarks on the final day of the meeting, Wednesday, April 20th in the “Highlights 2016: Vision for the Future” Plenary Session. As conference diehards, we will be there in person, but AACR have announced they plan to livestream it to the world. It’s a fitting finale to what is set to be a “must attend” meeting for those with an interest in cancer new product development and in particular, cancer immunotherapy.

What can we learn from AACR abstracts on TIM–3 and LAG–3?

There is some early clinical data that we will be checking out (no pun intended) on TIM-3 and LAG-3.

This weekend I will be at the annual meeting of The Association for Research in Vision and Ophthalmology (ARVO) in Fort Lauderdale.

I’m excited about attending because earlier in my career I worked at Alcon Laboratories on European IDE clinical trials for three novel intra-ocular lenses.

ARVO is the ophthalmology equivalent of AACR and is where scientists involved in drug, device research meet to discuss new findings and early stage research.

The title of meeting is “Visionary Genomics.”  After listening to the plenary session at the recent AACR annual meeting by Lynda Chin on how insights from cancer genomics are translating into personalized medicine, I’m looking forward to seeing the impact of genomics on vision research.

Sunday’s ARVO/Alcon keynote presentation is from Roderick McInnes who is the Canada Research Chair in Neurogenetics at McGill University in Montreal.

A presentation that is already generating some advance interest is Sunday’s presentation of the results from the Comparison of Age Related Macular Degeneration Treatments Trials (CATT).

Age related macular degeneration (AMD) is the leading cause of vision loss in those over 65 in the United States, with over 7 million people estimated to be at risk.  Once you have AMD in one eye, you have a 43% risk of developing it in the other eye over a  five year period, a scary statistic!

The first CATT clinical trial is between bevacizumab (Avastin®) and ranibizumab (Lucentis®), both similar anti-VEGF inhibitors that are derived from the same monoclonal antibody.  It will be interesting to see whether the data supports the current practice of off-label use of bevacizumab given its lower cost compared to ranibizumab.

The findings from this data will also potentially impact aflibercept (VEGF-Trap) that is being co-developed by Bayer and Regeneron.  In February, Regeneron submitted a biologics license application (BLA) to the FDA for the use of VEGF-Trap in wet AMD.

The initial results from the aflibercept phase III AMD trial announced late last year showed a non-inferiority to ranibizumab.  If aflibercept is approved and comes to market in 2012, depending on the CATT results, it may have to compete on price against off-label bevacizumab in AMD.  Whether a more convenient injection once every two months for VEGF-Trap (compared to monthly for Lucentis) is sufficient to justify a price premium, it will be interesting to watch the market dynamics in this space.

You can find more about the meeting on the ARVO conference website and they have also put up a blog for the meeting.   The theme of my blog posts over the next few days will be ophthalmology related, and I expect to be live tweeting from ARVO 2011 on Sunday and Monday.  I’ll also be aggregating tweets from the meeting (hashtag #ARVO11) on this blog.

VEGF Trap-Eye is a formulation of VEGF Trap (aflibercept) and is an anti-angiogenic agent that can be injected into the eye to stop the proliferation of blood vessels. Regeneron (REGN) are co-developing it with Bayer (BAY) and it is currently in clinical trials for the treatment of wet Age-Related Macular Degeneration (AMD), Diabetic Macular Edema (DME) and Central Retinal Vein Occlusion (CRVO).

Phase II DME clinical trial results presented at the
Angiogenesis 2010 meeting in Miami showed the primary endpoint of a
statistically significant increase in visual acuity over 24 weeks compared to
the standard of care (laser treatment) was met.

There are high levels of vascular endothelial growth factor (VEGF) associated with DME, so the news that VEGF Trap-Eye has biological activity in this disease is positive.What makes this data promising is the fact that DME is the leading cause of blindness in adults under 50 and there are 370,000 Americans with clinically significant DME with 95,000 new cases a year.

The ability to treat DME by an eye injection, rather than use an expensive laser will make it easier to treat the disease. It will be interesting to see what how the cost of treatment with VEGF Trap-Eye compares to laser therapy procedures, should the agent make it to market.

The recent pricing issue faced by Genentech with its VEGF inhibitors Lucentis
(eye indications) and Avastin (oncologic indications) are also relevant because
Regeneron are developing VEGF-Trap in cancer with it’s partner sanofi-aventis
(a client).

For VEGF Trap-Eye, Regeneron retains all U.S. marketing
rights, while Bayer has rights to market ex-US in return for a 50/50 profit
share with Regeneron.The results so far look promising and aflibercept looks like an interesting agent well worth watching as the development moves forward.
