Pfizer’s next-generation androgen receptor (AR) inhibitor Xtandi is the market leader in prostate cancer due to its established efficacy across prostate cancer segmentations and a lack of near-term generic competition. Bolstered by recent and planned expansions into additional prostate cancer segments, Xtandi will continue to be the leading option in this indication. Future expansion opportunities include potential use in combination with PARP inhibitors Talzenna or Rubraca in metastatic castration-resistant prostate cancer (mCRPC) patients. Xtandi is also being trialed in combination with leuprolide in the Phase III EMBARK study for non-metastatic hormone-sensitive prostate cancer patients progressing on definitive therapy. Potential expansion into this segment represents a noteworthy opportunity to improve outcomes earlier in the treatment paradigm, but the combination will have to demonstrate a significant benefit over existing localized treatment options to justify the additional clinical toxicity and high cost of Xtandi treatment.
