Philadelphia – it’s the final day of the American Association of Cancer Research (AACR) annual meeting, and it’s been one of the best AACR annual meetings of recent years, with cancer immunotherapy very much at the fore.

This morning, the plenary session at the meeting was: Oncology Meets Immunology: Not Just Another “Hallmark.”

Cancer immunotherapy is changing the paradigm of cancer treatment in many ways, which is why the title of today’s plenary was clever….

Readers will be aware of the classic Hallmarks of Cancer paper (open access) by Douglas Hanahan and Robert Weinberg, which provides a framework for understanding how how tumors develop (e.g. sustaining proliferative signaling, evading growth suppressors, resisting cell death, enabling replicative immortality, inducing angiogenesis, and activating invasion and metastasis). This landmark paper provides a way to understand where new cancer treatments could act.

Today’s plenary featured four presentations from leaders in the field of cancer immunotherapy:

  • Engineering Improved Cancer Vaccines, Glen Dranoff, Novartis Institutes for Biomedical Research
  • Leukocytes as targets for therapy in solid tumors, Lisa M. Coussens, OHSU Knight Cancer Institute, Portland
  • Fatal Attraction: A new story featuring the immune system and pancreatic cancer, Elizabeth M. Jaffee, Johns Hopkins University, Baltimore
  • The mechanistic basis of cancer immunotherapy, Ira Mellman, Genentech, Inc. South San Francisco.

The first three speakers I have to say did not live up to the promise of their billing, spending far too much time on “My Pet Project,” delving into the weeds of the research from their lab or group, rather than putting the landscape in context, providing strategic direction of where things are going and including fair balance across the work in the field, which is what I expected a plenary presentation to be about.

One of our highlights of the plenary (and the conference) was the presentation by Ira Mellman, Vice President at Genentech who along with Dan Chen, Cancer Immunotherapy Franchsise Head at Genentech, are the author of the paper that is fast becoming the equivalent of the classic Hallmarks paper for Cancer Immunotherapy: Oncology meets immunology: the cancer-immunity cycle. (open access).

Earlier in the meeting, I had the privilege to chat with Drs Ira Mellman (pictured left), Leisha Emens (Johns Hopkins) and Dan Chen (pictured right) for the Novel Targets podcast. They are three of the many “rock stars” of the cancer immunotherapy world.

What were our highlights of AACR 2015?

We’ve carefully selected our Top Ten presentations of this year’s AACR for subscribers – Ira Mellman’s was one of them – but who are the others?  Some of them could be found outside the main sessions in the fringe rooms.

You can login in below or can purchase access to read them in the box.

For the week of the AACR meeting, there’s $50 off the price of a quarterly subscription, that will get you not only our post-AACR conference coverage, but access to the library of content we’ve written for example on immuno-oncology.

We’ll be at four meetings, including ASCO in the next two months, so to paraphrase Frank Sinatra, “The best is yet to come”…….

Philadelphia – the 2015 annual meeting of the American Association for Cancer Research (AACR) is in full swing, with over 18,000 attendees, it’s probably the world’s largest meeting dedicated to cancer research. The theme is “Bringing Cancer Discoveries to Patients.”

AACR 2015 Annual Meeting Philadelphia

I challenge anyone not to attend, and come away inspired with new ideas on how the field of cancer research will evolve in coming years.

At this year’s annual meeting, not surprisingly, cancer immunotherapy is one of the hot topics. Yesterday there was the simultaneous publication of two papers in the New England Journal of Medicine (NEJM) to coincide with data presented at the meeting.

Pembrolizumab (Keytruda)  for the Treatment of Non–Small-Cell Lung Cancer

The conclusion of the paper by Edward B. Garon, MD (UCLA) et al was that:

Pembrolizumab had an acceptable side-effect profile and showed antitumor activity in patients with advanced non–small-cell lung cancer. PD-L1 expression in at least 50% of tumor cells correlated with improved efficacy of pembrolizumab.

The other paper published in the NEJM was for:

Pembrolizumab (Keytruda) versus Ipilimumab (Opdivo) in advanced Melanoma.

The conclusion of the paper by Caroline Robert, MD PhD, presented at AACR by Antoni Ribas, M.D., Ph.D.(UCLA) was:

The anti–PD-1 antibody pembrolizumab prolonged progression-free survival and overall survival and had less high-grade toxicity than did ipilimumab in patients with advanced melanoma.

This year’s AACR annual meeting is to paraphrase Bertrand Tombal, “a Grand Cru year”. Not only in cancer immunotherapy, but in metabolism, epigenetics and advances in drug discovery.

We’re excited about the prospect of another three days at the meeting, but in the meantime in this post there’s some top-line thoughts for subscribers on some of the data that caught our attention over the weekend.

In recognition of AACR, there’s $50 off a quarterly subscription if you wish to purchase access (offer valid only during the week of the meeting – ends this Friday!)  If you’ve been sitting on the fence for a while wanting to try out BSB, now is a good opportunity to dip your toes in the water.
