Comments

Trial for advanced or metastatic solid tumor, CRC included, that has progressed after at least one line of therapy.
Combination of an anti SHP2 with immunotherapy:
GDC-1971: SHP2 inhibitor. SHP2 promotes cancer cell survival and growth through the RAS pathway by transducing signals downstream from receptor tyrosine kinases (RTKs); this experimental inhibitor targets SHP2. It will be administrated as tablet or capsule in the trial.
Atezolizumab (Tecentriq®): PD-L1 checkpoint inhibitor; immunotherapy
In the expansion stage, Omeprazole (acid-reducing agent) will be added to the combination.
Even if the trial does not requiere particular mutations, trial might be of interest for KRAS and BRAF mutant, give the potential role of SHP2 inhibitors on their treatment. See Helpful Links
