How do we make CAR T cell therapy more safe and effective? How can we target solid tumors? In this episode we hear from two cell therapy pioneers: Dr Michael Jensen & Dr Michel Sadelain.
Interview with Dr Michel Sadelain
Dr Michel Sadelain (pictured) is Director of the Center for Cell Engineering at Memorial Sloan Kettering Cancer Center in New York. He’s spent the last 25 years pioneering new approaches to adoptive cell therapy.
Dr Sadelain and colleagues at Memorial were responsible for the development of what is known as the second generation Chimeric Antigen Receptor (CAR) T cell construct and for identifying CD19 as a target.
Using this target, the results in some blood cancers have been impressive, most notably in acute lymphoblastic leukemia, as we previously heard from Dr Stephan Grupp in Prologue 1: Promise of CAR T Cell Immunotherapy.
At the AACR 2016 annual meeting in New Orleans, Dr Sadelain gave a presentation on Turbo-charging CAR T cells, and how to make them more potent and effective.
Podcast listeners may recall in Episode 5, Dr Carl June and Dr Steven Rosenberg discussed the challenges of using CAR T cell therapy in solid tumors (link to episode 5).
In this episode, Dr Sadelain shares his thoughts on how to overcome the technical challenges they noted in targeting solid tumors, and address the lack of targets that aren’t also expressed on normal cells.
Interview with Dr Michael Jensen
Dr Michael Jensen is Director of the Ben Towne Center for Childhood Cancer Research at Seattle Children’s Research Institute.
One of the side effects associated with CAR T cell therapy is that severe toxicities, notably cytokine release syndrome and neurotoxicity, can occur in a small number of patients.
At the BMT Tandem meeting in Hawaii, he talked about ways in which CAR T cell therapy can be made safer and provide more durable remissions. On the podcast he also discusses his latest research and where the field is going.
As Dr Jensen notes in the podcast, CAR T cell therapy [currently] requires access to tertiary care centers, where intensive care and specialist expertise is available.
This means that even if the FDA approves the first CD19 directed CAR T cell therapy in 2017, it’s use is likely to be restricted to specialist transplant centers.
