in a German study on CD19 CAR-T cells in autoimmune diseases such as systemic lupus erythematosus (SLE), a potentially life threatening condition – what can we learn from prior data? A short thread 🧵...
There are no words to describe the sadness and utter desolation one feels when a dear friend of 30 years suddenly passes. Gone far too young, may he rest in peace. I shall miss his exuberant spirit greatly.
I'm delighted to say we hit our 5-year anniversary this week for BSB as a specialist oncology paid subscription service... many thought we'd last 6 mon - here we still are, going from strength to strength! Thanks to all our supporters and fans.
Nice review from Jim Allison and colleagues on "Fundamental mechanisms of immune checkpoint blockade therapy" - explaining diffs in targeting PD-1 and CTLA4:
There is a huge need to develop immunotherapies to enhance T cell responses against "immunologically 'cold' tumours" with low T cell infiltration and neoantigen burden. Despite numerous company efforts, there have been few successes to report...
Whoa 3 hours post vaccine waiting for the next

session and light headed with tingling hands, headache and chills. My T cells are busy doing their job! 🙏
This has to be one of the most idiotic, rude, and ill advised tweets I’ve seen in 2020 given the sheer cultural diversity & productivity of cancer research labs in my stream every damn day...
For those who wondered why IDO didn't work, check out this paper - MOA of unlocking 2 T cell brakes clearly did not address any of these key TME complications:
One of my favourite memories of
@Becker_MichaelD
was a v spirited debate in we had in
#ASH10
poster hall on PI3K - whether or not Semafore's SF1126 was better than Calistoga's (idelalisib). At the end he was still gracious and smiling, always the gentleman. RIP Michael.
Having experimented w/ a low carb diet for 6 weeks, I can say that there is noticeably less knee pain. Of course, it's anecdotal and correlation ≠ causation, but then saw this paper:

Who knew? Differences in anti-tumour efficacy of CAR-T cells among lymphoma patients w/ different clinical outcomes may be due to loss of CCR7 gene expression & other related factors:
Interesting chat w/ anti-mask neighbour... asked how she would feel if we had seen 3 fatal jumbo jet crashes a day since March 1st? "That's a horrific thought!" Pointed out this is what total US deaths from Covid represents in the same time. "Oh no, it can't possibly be!"
Have been practicing social distancing for the last month, my neighbours laughed at me for being paranoid. Now they’re all panicking and freaking out. No need to stress, stay calm and focused.
6 Years ago yesterday we launched the BSB subscription service - can't believe it has done so well with people still subbed since that very first month! Really appreciate all the feedback, comments, and interactions we've had with all our readers.
For all the scientists and data geeks in my stream... this narrated coronavirus post is an excellent read - v sobering - reminds me of how much we can learn from self isolation like my buddy in HK

Irony of this is that at ECCO15 a lot of KOLs HATED the idea of IO + chemo... really hated it to the point many thought it was a truly bad idea. They wanted IO-IO combos. Now they hate the tox with IO-IO. Funny how things turn out sometimes.
So far only 3 MoA have succeeded in I/O combo Ph3 trials:
- Chemo combo in NSCLC/SCLC/TNBC
- TKI or VEGF combo in RCC
- CTLA4 combo in melanoma and RCC
All proven MoA as

My bet is on T-Vec being the 4th.

2 yrs ago we said that bispecifics were an emerging area in oncology R&D... people scoffed. Now next gen T cell bispecifics might seriously challenge CAR T cell therapies, here's why:
New CAR-T cell paper implicates cellular elements other than T cells, suggests novel links betw syst inflammation & characteristic neurotox symptoms via MSK:
Conference organisers keep sending me surveys about attending their meeting live. No! Not for a while and here's why - risk of Covid-19 transmission remains, as this JAMA study clearly illustrates:

Neoantigen quality not quantity - nice opinion piece based on TRACERx data from

@CharlesSwanton
- confirms Ton Schumacher’s assertion a couple of years ago:
“So, you’re telling me that you can reprogram T cells to find & kill cancer cells, but it took 4 months to get my mother an appointment w/ a neurologist; she spent 2 hours in the waiting room; & then she got an exorbitant bill that read, ‘This is not a bill’?”
Painfully true 🤦🏻♂️
If you're 3rd or later to market in a cancer niche then you'd better show up with better OS, much improved safety profile, or risk smaller revenues 'cos mkt leaders will already have formularies wrapped up and you will have less MD loyalty baked in. That is all.
Lovely character piece from Adam about a well loved biotech analyst many of us will miss. Will never forget Mark rescuing me from a company briefing when they tried to throw me out, "Don't worry, she's with me!" RIP Mark
@daphnezohar
Agreed. I’d argue from my recent experiences of US healthcare that maybe
@ewarren
and others should direct some well deserved ire at hospitals and their gross overcharging, which is far more grievous
We need to look at learnings from our antibody experiences with immune agonists & checkpoints. Here's an interview with
@DanChenMDPhD
, who does a superb job explaining why things didn't always work out as expected:
A beautiful story for everyone in oncology R&D; what does a CR really mean for a man with refractory melanoma and the oncologist treating him? Last 10 secs from Dr Diab are the kicker:
Opening up America while coronavirus is still rampant is a recipe for disaster. Look at what happened in Singapore & Hokkaido where they flattened considerably, opened up now have a 2nd cluster surge! What could possibly go wrong in US? 😱
One of the fun aspects of the

meeting is people watching...
It's not as strange as it might seem.
Unlike other major cancer conferences, you soon learn ASH has an entirely different flow and vibe to its poster sessions. A 🧵
Many are familiar with bispecifics and T cell engagers, so how about a bispecific dendritic T cell engager (BiCE) to potentiate anti-tumour immunity?
This one comes from Israel where researchers have created a dual molecule to target CLEC9A and PD-1:
Why do this this?

They lost all credibility after the Wakefield debacle so now we have a sorta tabloid for science with buzzfeed-like headlines and teases. Sigh.
