Abstract

Cancers with specific genetic mutations are susceptible to selective kinase inhibitors. However, there is a wide spectrum of benefit among cancers harboring the same sensitizing genetic mutations. Herein, we measured apoptotic rates among cell lines sharing the same driver oncogene following treatment with the corresponding kinase inhibitor. There was a wide range of kinase inhibitor-induced apoptosis despite comparable inhibition of the target and associated downstream signaling pathways. Surprisingly, pretreatment RNA levels of the BH3-only pro-apoptotic BIM strongly predicted the capacity of EGFR, HER2, and PI3K inhibitors to induce apoptosis in EGFR-mutant, HER2-amplified, and PIK3CA-mutant cancers, respectively, but BIM levels did not predict responsiveness to standard chemotherapies. Furthermore, BIM RNA levels in EGFR-mutant lung cancer specimens predicted response and duration of clinical benefit from EGFR inhibitors. These findings suggest assessment of BIM levels in treatment-naïve tumor biopsies may indicate the degree of benefit from single-agent kinase inhibitors in multiple oncogene-addiction paradigms. Significance: In several oncogene-addiction paradigms, assessment of BIM RNA levels identifies those cancers that fail to have substantial apoptotic responses to kinase inhibitors. BIM RNA levels may be assessed in diagnostic cancer specimens to predict which patients will receive less benefit from single-agent kinase inhibitors. Cancer Discovery: 1(4); 352–65. ©2011 AACR.

  • Levels of BIM are predictive of response to targeted therapy in EGFR mutant lung cancers, HER2-amplified breast cancers and PIK3CA mutant cancers.

    “Indeed, we observed that levels of the pro-apoptotic BH3-only Bcl2 family member, BIM, are predictive of response to targeted therapy in EGFR mutant lung cancers, HER2-amplified breast cancers and PIK3CA mutant cancers (Faber et al., 2011).”
  • Although erlotinib or lapatinib inhibited EGFR and HER2 and downstream signaling in EGFR mutant and HER2-amplified cancers, only those cell lines with high levels of BIM underwent marked apoptosis.

    “In this study, although erlotinib or lapatinib inhibited EGFR and HER2 and downstream signaling in EGFR mutant and HER2-amplified cancers, respectively, only those cell lines with high levels of BIM underwent marked apoptosis.”
  • BIM protein is normally induced following inhibition of EGFR and HER2 in these cancers.

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.
