This one is for adults with primary advanced or recurrent endometrial cancer.
"This new approval is based on data from the Phase 3 NRG-GY018 trial, also known as KEYNOTE-868. Results reported last year in the New England Journal of Medicineshowed a 70% lower risk of disease progression when patients were treated with pembrolizumab and chemotherapy."

"Novartis’ anti-TIM-3 antibody has flunked a phase 3 blood cancer trial, prompting the Swiss drugmaker to pull the drug candidate from its pipeline. The failed study was the biggest test to date of an immuno-oncology target into which a who’s who of leading drug developers have pumped money."

AlphaFold & PDL1
"Here, we test a protein design pipeline that uses iterative rounds of deep learning (DL)-based structure prediction (AlphaFold2) and sequence optimization (ProteinMPNN) to design autoinhibitory domains (AiDs) for a PD-L1 antagonist."

The effects of the CTLA4 deletion were not very surprising, what's fascinating here is how it compares to the double mutants (PD1/CTLA4).
"CTLA4 disrupted CART19 cells display prolonged surface CAR expression, increased proliferation, and enhanced CART19 effector function supported by unopposed CD28 co-stimulation, which is lost in CART19 cells deficient for both PD-1 and CTLA4"

Very interesting case report of pulse methylprednisolone in treatment of steroid-refractory #Immune #CheckPointInhibitor #pneumonitis
We also treated a patient with a grade IV pneumonitis with high dose steroid. My observation is a very rapid improvement, within 48h.
Further research is needed but it could be promising for life-threatening immune checkpoint inhibitor reaction
What if we could trace #cytotoxic #Tcells throughout the human body before and during #cancer #immunotherapy?
Researchers at the University of Groningen have used a CD8-specific positron emission tomography (#PET) tracer in a phase 1/2 clinical trial. Patients with solid tumors were imaged before and ~30 days after starting treatment with #antibodies against PD-L1, PD-1, and/or CTLA-4.

"Won et al. demonstrate that PD1
inhibitor treatment alone induces
myocarditis in A/J mice, creating a mouse model for immune-checkpoint-inhibitor-associated myocarditis."
