Blocking the tyrosine kinase cell-cycle progression regulator WEE1 may help to reinstate tumour immunogenicity and potentiate the effects of immune checkpoint inhibitors 

Early-phase trials suggest that sitravatinib may reboot the tumour response to PD-1 inhibitors, but confirmation of efficacy is required and strategies are needed to adjust tolerability  

Developing therapies for cancers harbouring KRAS mutations has proven difficult but PROTACs, acting via targeted protein degradation, may help combat previously undruggable proteins 

A study associates reductions in ctDNA with major pathologic response following neoadjuvant atezolizumab in resectable stage IB–IIIB NSCLC, but clinical application is still some way off

Sub-group analyses of CheckMate 227 part 1 provide reassurance but no definite guidance regarding standard treatment for different patient sub-groups 

Results from an exploratory analysis of the IMpower010 trial confirm that there is a correlation between tumour-cell PD-L1 expression and disease-free survival 

Along with treatments with immune checkpoint inhibitors and cellular therapies, other immunotherapies are currently under investigation

Immunotherapy plus chemotherapy as first-line treatment choice for advanced disease without oncogene mutations, irrespective of ethnicity and PD-L1 status 

In the first interim analysis of the ORIENT-31 trial, progression-free survival was slightly improved in patients who progressed after EGFR TKI, but mature results are needed to confirm whether combination therapy represents a new therapeutic option in this setting

However, regulatory and financial issues will shape when and where this happens
