The principal investigator is Ferdinandos Skoulidis.

In advanced NSCLC, patients with mutations in the STK11 and/or KEAP1 genes respond better to dual immune checkpoint blockade (ICB) using a combination of a PD-L1 inhibitor (durvalumab) and a CTLA4 inhibitor (tremelimumab), along with chemotherapy, compared to using a PD-L1 inhibitor alone.

The phase III POSEIDON trial demonstrated that these genetic alterations are linked to resistance against PD-(L)1 inhibitors, but dual ICB can overcome this resistance.

This combination therapy reprograms the tumor microenvironment, shifting immune cells towards more effective anti-tumor responses, particularly involving CD4+ effector cells and tumoricidal myeloid cells, leading to improved clinical outcomes.
