PQR620 HCl is a novel, potent, selective and brain penetrant inhibitor of mTORC1/2 which plays a fundamental role in cell proliferation, differentiation, growth and survival. The PI3K/AKT/mTOR pathway is an important therapeutic target in lymphomas. PQR309 is a dual PI3K/mTOR inhibitor that has shown in vitroanti-lymphoma activity (Tarantelli et al, ASH2015) and is in phase 2 trial (NCT02249429, , NCT02723877, NCT02669511). PQR620 is a novel mTORC1/2 inhibitor that has shown preclinical activity in solid tumor models (Beaufils et al, AACR 2016). The novel mTORC1/2 inhibitor PQR620 had in vitro and in vivo anti-lymphoma activity as single agent. In vivo experiments showed that both PQR620 and the dual PI3K/mTOR inhibitor PQR309 can strongly benefit from the combination with the BCL2 inhibitor venetoclax.
