Abstract

TPS200Background: Previous randomized, phase 3 trials have shown the efficacy of adding docetaxel, abiraterone acetate, enzalutamide, or apalutamide to ADT in improving overall survival and/or radiologic progression-free survival (rPFS) in patients with metastatic hormone-sensitive prostate cancer (mHSPC). However, these combinations are associated with an increased risk of adverse events (eg, fatigue, rash, and cardiovascular events). Darolutamide is a structurally distinct and highly potent androgen receptor inhibitor. In the ARAMIS study, darolutamide has been shown to significantly reduce the risk of death by 31% and have a favorable safety profile in men with nonmetastatic castration-resistant prostate cancer. It has a low incidence of central nervous system−related adverse events, which may be explained by its distinct low blood−brain barrier penetration. Darolutamide has also been shown to have a low potential for drug−drug interactions, allowing flexibility with concomitant medications. ARANOTE will evaluate the efficacy and safety of darolutamide plus ADT in patients with mHSPC (NCT04736199). Methods: ARANOTE is an international, multicenter (ex-US), randomized, double-blind, placebo-controlled, phase 3 study in patients with histologically or cytologically confirmed adenocarcinoma of the prostate and documented metastatic disease by conventional imaging (eg, computed tomography or magnetic resonance imaging) who started ADT ≤12 weeks before randomization. In total, 555 patients will be randomized 2:1 to darolutamide 600 mg twice daily or placebo, plus ADT. Patients will be stratified by the presence of visceral metastases, assessed by central review, and prior local therapy. Patients will be evaluated every 12 weeks for efficacy, safety, and quality of life (using the FACT-P questionnaire) during treatment and active follow-up post treatment. For long-term follow-up, patients will be contacted by telephone every 12 weeks. The primary endpoint is rPFS; secondary endpoints include overall survival, time to castration-resistant prostate cancer, time to prostate-specific antigen progression, and safety. Recruitment is ongoing, and the first patient first visit was on February 23, 2021. The estimated study completion date is September 2025. Clinical trial information: NCT04736199.
