At least 60 patients should be in ECOG 2. When 40 patients in ECOG 0-1 are included, the inclusion criteria will change to only ECOG 2. 7. At least one lesion, not previously irradiated and not chosen for biopsy during the study screening period, that can be accurately measured at baseline according to RECIST 1.1.

Previous malignancy (except non-melanoma skin cancers, and the following in situ cancers: bladder, gastric, oesophageal, colon, endometrial, cervical, melanoma or breast) unless a complete remission was achieved at least 2 years prior to study entry. 11. Significant gastrointestinal disorder that results in significant malabsorption, requirement for intravenous alimentation, or inability to take oral medication. 12. Mean resting corrected QT interval (QTc) > 470 msec (females) or > 450 msec (males) using the screening clinic ECG machine derived QTc value. 13. Inadequate bone marrow reserve or organ function as demonstrated by any of the following laboratory values: -Absolute neutrophil count <1.5x109/L -Platelet count <100x109/L -Haemoglobin <9.0g/dL -Alanine aminotransferase (ALT) >2.5 times the upper limit of normal (ULN) if no demonstrable liver metastases or > 5 times ULN in the presence of liver metastases -Aspartate aminotransferase (AST) >2.5 times ULN if no demonstrable liver metastases or > 5 times ULN in the presence of liver metastases -Total bilirubin >1.5 times ULN if no liver metastases or >3 times ULN in the presence of documented Gilbert’s Syndrome (unconjugated hyperbilirubinaemia) or liver metastases -Serum creatinine >1.5 times ULN concurrent with creatinine clearance <50mL/min [measured or calculated by Cockcroft and Gault equation]—confirmation of creatinine clearance is only required when creatinine is >1.5 times ULN 14. History of hypersensitivity of active or inactive excipients of sotorasib or drugs with a similar chemical structure/class to sotorasib. 15.
