48 Appendix • All RAS cancer epidemiology statistics are estimated using tumor mutation frequencies from Foundation Medicine Insights March 2022 and scaled to estimated patient numbers using cancer incidence from ACS Cancer Facts and Figures 2023: • RAS mutations include: KRAS G12(A,C,D,F,L,R,S,V), KRAS G13(C,D,R,V), KRAS Q61(E,H,K,L,P,R) NRAS G12(A,C,D,R,S,V), NRAS G13(C,D,R,V), NRAS Q61(H,K,L,R), HRASG12(C,D,S,V), HRASG13(C,D,N,R,S,V), HRASQ61(K,L,R). • Includes 13 major solid cancer types: non-small cell lung cancer, colorectal, pancreatic ductal adenocarcinoma, renal, esophageal, head and neck squamous cell, ovarian, stomach, biliary, and carcinomas of unknown primary (CUP), and advanced melanoma, bladder and endometrial cancers causing mortality. • KRASQ61H epidemiology statistics include multiple myeloma in addition to 13 major solid cancer types named above • RAS mutations drive 30% of human cancers per Prior et al., Cancer Research 2020 • Mouse tumor responses assigned according to mRECIST (modified from Gao et al. Nat Med. 2015): • mPD = progressive disease; mSD = stable disease; mPR = partial response; mCR = complete response
