SHP2 Inhibition Prevents Adaptive Resistance to MEK Inhibitors in Multiple Cancer Models
Open accessPublished version of a preprint
Abstract
Adaptive resistance to MEK inhibitors (MEKi) typically occurs via induction of genes for different receptor tyrosine kinases (RTK) and/or their ligands, even in tumors of the same histotype, making combination strategies challenging. SHP2 (PTPN11) is required for RAS/ERK pathway activation by most RTKs and might provide a common resistance node. We found that combining the SHP2 inhibitor SHP099 with a MEKi inhibited the proliferation of multiple cancer cell lines in vitro. PTPN11 knockdown/MEKi treatment had similar effects, whereas expressing SHP099 binding–defective PTPN11 mutants conferred resistance, demonstrating that SHP099 is on-target. SHP099/trametinib was highly efficacious in xenograft and/or genetically engineered models of KRAS-mutant pancreas, lung, and ovarian cancers and in wild-type RAS-expressing triple-negative breast cancer. SHP099 inhibited activation of KRAS mutants with residual GTPase activity, impeded SOS/RAS/MEK/ERK1/2 reactivation in response to MEKi, and blocked ERK1/2-dependent transcriptional programs. We conclude that SHP099/MEKi combinations could have therapeutic utility in multiple malignancies. Significance: MEK inhibitors show limited efficacy as single agents, in part because of the rapid development of adaptive resistance. We find that SHP2/MEK inhibitor combinations prevent adaptive resistance in multiple cancer models expressing mutant and wild-type KRAS. Cancer Discov; 8(10); 1237–49. ©2018 AACR.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
