Marcel R.M. van den Brink, M.D., Ph.D.At the 2014 Society for Immunotherapy of Cancer (SITC) annual meeting at National Harbor, MD, one of the presentations that caught my attention was by Marcel van den Brink MD PhD (@DrMvandenBrink), pictured right, from Memorial Sloan-Kettering Cancer Center in New York. (picture courtesy of MSKCC with permission).

Dr van den Brink, who is Head of the Division of Hematologic Oncology and Alan.N. Houghton Chair, gave a fascinating talk entitled, “The role of the Intestinal Microbiome on GvHD” (Graft versus Host Disease).

Think of the yogurt pots and probiotic drinks we see in the supermarket with “beneficial” bacteria. We’re familiar with the idea that the make up of the millions of bacteria in our gut can make a difference to our digestion and health.

Well, it turns out it can make a difference to our immune system too. Research presented at the recent SITC meeting by Dr van den Brink showed that manipulating the bacteria in the gut could potentially help the thousands of patients around the world who receive a bone marrow transplant (BMT).  BMT is a gruelling procedure that many leukemia, myeloma and lymphoma patients have to face as part of their treatment protocol.

Sadly, about 20%* of people who receive an allogeneic bone marrow transplant from an unmatched donor die from Graft versus host disease (GvHD)

* According to 2010-2011 data from the Center for International Blood and Marrow Transport (CIBMTR), GvHD was the cause of death in 19-23% of people who received an allogeneic hematopoietic stem cell transplant.

After his informative and interesting presentation at SITC, Dr van den Brink spoke with BSB about his findings and what’s on the horizon for the treatment of GvHD.

Over the course of a half hour conversation, he covered some of the new treatment options, one of which may change the standard of care, and the rational some companies are pursuing by targeting the innate immune system.

For those interested in CAR-T cell therapy and the promise of allogeneic CAR-T cells, Dr van den Brink kindly talked about some unpublished data from MSKCC about why we have not seen GvHD in patients who receive allogeneic CAR-T cells.

GvHD is an important topic, and one that deserves more attention. I expect we will here a lot more about it at ASH this year so reading this interview will, hopefully, help you better put that data in context.

The Inquirer yesterday reported on that start-up Juno Therapeutics (Juno) are now in control of a legal dispute between St Jude Children’s Hospital (St Jude) and the University of Pennsylvania (Penn) over chimeric antigen receptor (CAR) intellectual property that contributed to the development of CTL019, licensed by Penn to Novartis. Thanks to @lomu_j for sharing this news on Twitter.

According to the Inquirer, last month Juno entered an agreement with St Jude to commercialize their CAR T-cell technology, which gave them the right to “control, pursue and defend” the dispute between Penn and St Jude.  On December 18, Juno’s intervention was approved in Federal District Court in Philadelphia.

(Update Jan 10: Zack Seward (@ZackSeward) provides additional commentary on WHYY Philadelphia newsworks on “The high-stakes legal fight over a ‘cancer cure from Penn.’ He reports that St Jude have every confidence in their patent.
