Datamonitor Healthcare Oncology Disease Analysis: Prostate Cancer

September 15, 2023

Pfizer’s next-generation androgen receptor (AR) inhibitor Xtandi is the prostate cancer market leader due to its established efficacy across multiple patient segments and a lack of near-term generic competition. Xtandi is being trialed in combination with leuprolide in the Phase III EMBARK study for non-metastatic hormone-sensitive prostate cancer (nmHSPC) patients progressing on definitive therapy, where it has yielded positive data, leading Pfizer to submit an NDA which has been given priority review by the FDA. 

PARP inhibitors Rubraca and Lynparza were both approved in the US in May 2020 for the treatment of metastatic castration-resistant prostate cancer (mCRPC) patients following AR inhibitor therapy. Rubraca received accelerated conditional approval in mCRPC with a deleterious BRCA mutation (germline and/or somatic), while Lynparza received full approval for use in the broader homologous recombination deficient (HRD) population. To potentially differentiate the PARP assets, both have been trialed in the first-line setting of mCRPC; Rubraca in combination with Xtandi against Xtandi alone, and Lynparza with abiraterone against abiraterone alone. The latter trial has led to an approval, though it is restricted to the BRCAm population, dashing hopes that it would support a wider label.
