Paris – amazingly it’s now 3 years since we interviewed Cellectis (NASDAQ: $CLLS) CEO André Choulika and CSO Philippe Duchateau (See post: Can Cellectis revolutionise CAR T cell therapy):

Since then, we’ve followed the company over time, including an interview with one of their leading scientists, Dr Julianne Smith at ASH 2014, followed by the initial results of their first allogeneic CAR T cell therapy UCART19 presented at #ASH15 by Professor Qasim.
It’s hard to believe 3 years have gone by so quickly! As regular readers know what we often do on BSB is follow stories longitudinally, so while in Paris for an Immuno-Oncology Summit we thought it a rather timely opportunity to revisit Cellectis and take stock of where they’re at and ask what the future may hold for them?
With the recent news that Gilead have acquired Kite Pharma, there’s going to be a lot of interest in what companies such as Cellectis are doing to bring allogeneic “off the shelf” CAR T cell therapy to market.
This is the penultimate post in our summer mini-series on gene editing and allogeneic CAR T cell therapy and features a candid interview with Dr Philippe Duchateau, Chief Scientific Officer, at Paris based Cellectis.

The immuno-oncology space continues to get both interesting and also very crowded with over 20 chimeric antigen receptor (CAR) T cell therapies now in development. Originally, the excitement began with the University of Pennsylvania’s dramatic announcement regarding the first two advanced CLL patients they successfully treated, leading to a collaboration with Novartis and spurring a new ‘arms race’ development in this niche.
While most of the CAR T cell therapy data since has largely focused on acute lymphoblastic leukemia (ALL) and to a lesser extent, non-Hodgkins lymphoma (NHL), many have been wondering what was happening on the CLL front? Has hope been abandoned there or will we see a renaissance occur? It is of particular relevance with the Abbvie/Genentech announcement that venetoclax has positive data in CLL patients who have the Del17p mutation and filing is likely here in this subset soon. Therapies such as ibrutinib and idelalisib are already approved in refractory CLL and may also have a future role to play here.
Do we need suicide switches for CAR T cell therapies such as Bellicum and Cellectis are developing or not?
Meanwhile, other hematologic malignancies are also being explored, including multiple myeloma. Why would a CD19 CAR work in a disease long considered to be CD19-negative in advanced, refractory disease?

What about progress with solid tumours? Many commentators and investors have been highly sceptical of the chances of success here following the advent of positive checkpoint data beyond metastatic melanoma and early CAR data in mesothelin cancers.
To answer these questions and also get a flavour for where things are headed with CAR T cell therapies, we recently interviewed one of the leading experts in this field, Dr Carl June (U Penn).

As cancer becomes increasing complex with adaptive responses to therapeutic intervention, so our knowledge and strategies for overcoming it must also adapt and improve. Immunotherapy – in several forms – is probably the hottest topic on the landscape at the moment with both checkpoint inhibitors and chimeric antigen receptor technology (CART) vying for air time and attention but where are these approaches going and how can we harness the immune system more effectively?
One of the things I like most about AACR meetings is that there are nearly always some strategic gems emerging from the scientist-physician thought leaders if only you stop to think about how the field can rapidly change by looking at the early patterns that are emerging.
Here’s the first part of a synopsis of what I learned at the recent Molecular Targets meeting in Boston, some of these findings may well have a major impact on cancer research over the next few years…
