[Non-metastatic castration-resistant prostate cancer (M0CRPC) - Apalutamide in high-risk M0CRPC: case reports from the SPARTAN study and the apalutamide compassionate use program]

The occurrence of distant metastases represents a prognostically unfavourable turning point in non-metastatic castration-resistant prostate cancer (M0CRPC). M0CRPC patients with a short PSA doubling time have a particularly high risk of progression. For a long time, there was no further treatment option for these patients apart from watchful waiting while maintaining classic androgen deprivation therapy (ADT). Apalutamide, a next-generation anti-androgen available since January 2019, significantly increased metastasis-free survival compared with placebo in the pivotal SPARTAN trial in patients with high-risk M0CRPC. The presented patient cases from SPARTAN and the apalutamide compassionate use program are examples of the beneficial effects that apalutamide can achieve in the M0CRPC setting.
