The first virtual 2021 AACR annual meeting starts tomorrow in earnest and we’ll be posting throughout the conference with various highlights and analysis.
There’s an explosion of new targets, novel combinatorial partners, expanding strategies and even an increasing number of companies entering the bispecific niche beyond the regular players we have covered in the past.
In our final Preview post we’re highlighting some of the AACR21 presentations which caught our attention, the science behind them, and some of questions we hope to see answered.
Stay tuned for our conference coverage and post meeting interviews!

Virtual meetings mean we miss the fun of German pop-up sausage stands and focus solely on the new emerging clinical data!
EHA25 Virtual, Not-In-Frankfurt – There’s a lot of commercial interest in CD20 x CD3 bispecifics, and in this post we’re taking a look at some of the latest clinical data presented at recent ASCO and EHA virtual meetings. Companies mentioned include Regeneron, Roche/Genentech, Genmab/Abbvie, Xencor, and IGM Biosciences.
Any analysis of a rapidly evolving and fast-moving landscape only represents a snapshot in time at the point it was taken, and this post is not intended to be a comprehensive landscape report, you’d pay a lot more than a yearly sub to BSB for that, but we’ve been following the field, and there are some trends emerging.
What makes it interesting is there is some nuance required in the interpretation of data, and with that in mind we spoke to an investigator at the forefront of clinical research who has done trials with several of the CD20 x CD3 bispecifics in development; the insights were quite illuminating.
This post offers an update on the CD20 bispecific landscape, analysis of some of the recent data at EHA and ASCO, as well as expert opinion, what more could you ask for?

Coney Island Roller Coaster
In the roller coaster of life that is oncology R&D, molecules come and molecules go… a rare few reach blockbuster heights while many others are quietly packed off to dog drug heaven, never to be seen or heard of again.
This is also very true of targets as well…
What about the in-between space?
Unfortunately, that’s where most molecules and cancer targets end up – into a deep black nothingness where we seek the high affinity targets with low grade side effects – and fall short in some way. It’s a frustrating place to be, to be sure.
One of these conundrums is compounds against CD123 (IL3Rα), which have been in the spotlight on and off this year and are turning out to be a rather mixed bag.
After our recent update on Cellectis and their CD123 direct CAR T cell therapy (UCART123), I wasn’t expecting to write any more on this until ASH in mid December. How wrong that prediction turned out to be!
Today we have quite a few things to discuss on this topic, so if interested in CD123 in hematologic malignancies and going beyond that to find better targets in AML then this is the poster for you…

This morning, like many folks, I woke up to the latest immuno-oncology news on the bispecific front that Xencor, a Los Angeles based biotech, announced their latest collaboration, this time with Novartis.
Over the last few years, we have seen a surfeit of bispecifics emerge that are focused on stimulating the immune system, particularly with regard to T cells and natural killer (NK) cells, as well as antigen targets on the surface of tumours. The first one approved was Amgen’s blinatumomab (Blincyto), a CD19 targeted bispecific for the treatment of acute lymphoblastic leukemia (ALL), which we have written extensively about.
The Xencor/Novartis deal has a number of interesting implications that are well worth exploring in more depth that go far beyond the information provided in the press release.
