9. Female subject is pregnant or lactating/breastfeeding or planning to become pregnant or breastfeed during treatment and for an additional 7 days after the last dose of sotorasib.
10. Female subjects of childbearing potential unwilling to use an effective method of contraception during treatment and for an additional 7 days after the last dose of sotorasib.

14. Concomitant use of drugs, including herbs and food additives, with a pharmacokinetic or pharmacodynamic interaction, as assessed with most recent KNMP kennisbank and uptodate.com drug interaction databases.
15. Donation of plasma or blood (450ml or more) less than 2 months before start of the study.

20. History of internal bleeding of any genesis.
21. Known present congenital or acquired bleeding disorders.
22. History of liver disease.
23. History suggestive of esophageal (including esophageal spasm, esophagitis), gastric, or duodenal ulceration or bowel disease (including but not limited to peptic ulceration, gastrointestinal bleeding, ulcerative colitis, Crohn's disease, or irritable bowel syndrome); or a history of gastrointestinal surgery other than uncomplicated appendectomy.
24. Known gastrointestinal disease without active ulceration that can potentially lead to bleeding complications.
25. History of vascular retinopathy.
26. Known bronchiectasis.
27. History of pulmonary bleeding.
28. The following conditions known in medical history: coronary heart disease, previous cerebrovascular accident (CVA) or transient ischaemic attack.
29. Positive Hepatitis B Surface Antigen (HepBsAg) (indicative of chronic Hepatitis B or recent acute hepatitis B). Negative HepBsAg with a positive for hepatitis B core antibody (Hepatitis B core antibody testing is not required for screening, however if this is done and is positive, then hepatitis B surface antibody \[anti-HBs\] testing is necessary. Undetectable anti-HBs in this setting would suggest unclear and possible infection and needs exclusion).
30. Positive Hepatitis C virus antibody: Hepatitis C virus RNA by polymerase chain reaction (PCR) is necessary. Detectable Hepatitis C virus RNA suggests chronic hepatitis C.
