Supplementary Figure 5: Xenograft models of KRASG13D and KRASQ61K are insensitive to RMC-4550.

Daily oral administration of RMC-4550 (30 mg/kg) to athymic nude mice bearing (a) HCT-116 (KRASG13D) or (b) CALU-6 (KRASQ61K) xenograft tumors did not produce significant tumor growth inhibition. Treatment with RMC-4550 was well tolerated in both models, as assessed by body weight (c,d). Source data is provided in Supplementary Table 9.
