Abstract

Metastatic prostate cancer is treated with drugs that antagonize androgen action, but most patients progress to a more aggressive form of the disease called castration-resistant prostate cancer, driven by elevated expression of the androgen receptor. Here we characterize the diarylthiohydantoins RD162 and MDV3100, two compounds optimized from a screen for nonsteroidal antiandrogens that retain activity in the setting of increased androgen receptor expression. Both compounds bind to the androgen receptor with greater relative affinity than the clinically used antiandrogen bicalutamide, reduce the efficiency of its nuclear translocation, and impair both DNA binding to androgen response elements and recruitment of coactivators. RD162 and MDV3100 are orally available and induce tumor regression in mouse models of castration-resistant human prostate cancer. Of the first 30 patients treated with MDV3100 in a Phase I/II clinical trial, 13 of 30 (43%) showed sustained declines (by >50%) in serum concentrations of prostate-specific antigen, a biomarker of prostate cancer. These compounds thus appear to be promising candidates for treatment of advanced prostate cancer.

  • The ability of MDV3100 to inhibit androgen receptor transcriptional activity and demonstrate clinical efficacy in a phase I/II trial suggests that ligand-directed therapeutics might still have a place in future treatment regimes.

    “The ability of these molecules to inhibit AR transcriptional activity and demonstrate clinical efficacy in a phase I/II trial of patients with CR tumors, in the case of MDV 3100, suggests that ligand-directed therapeutics might still have a place in future treatment regimes.”
  • MDV3100 demonstrated clinical efficacy in a phase I/II trial of patients with castration-recurrent tumors.

    “The ability of these molecules to inhibit AR transcriptional activity and demonstrate clinical efficacy in a phase I/II trial of patients with CR tumors, in the case of MDV 3100, suggests that ligand-directed therapeutics might still have a place in future treatment regimes.”
  • MDV3100 binds to the ligand-binding domain of the androgen receptor, similarly to bicalutamide.

    “EPI-001 targets the NTD of the AR (80), whereas MDV 3100 binds to the LBD (81), similarly to bicalutamide.”
  • The ARE repeat reporter (4X-ARE, firefly luciferase) has been previously described.

    “The ARE repeat reporter (4X-ARE, firefly luciferase) has been previously described (Tran et al., 2009).”

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.
