A clinical study found that the elimination half-lives of darolutamide and ketodarolutamide at steady-state were 15.8 hours and 10.0 hours, respectively, with these half-lives being independent of dosage across a dose range of darolutamide of 200 to 1,800 mg/day. The elimination half-life of darolutamide is far shorter than that of enzalutamide (e.g., 1.6 hours vs. 18.3 hours in mice). The clearance of darolutamide following intravenous administration is 116 mL/min. Excretion
After a single oral dose of darolutamide, more than 95% of the dose is excreted in urine and feces within one week following administration. A total of 63.4% darolutamide-related material is recovered in urine (about 7% as unchanged darolutamide) and a total of 32.4% darolutamide-related material (about 30% as unchanged darolutamide) is recovered in feces. Variability
No clinically significant differences in the pharmacokinetics of darolutamide have been observed in men with nmCRPC on the basis of age (48 to 95 years), race (white, Asian, black), mild-to-moderate renal impairment, or mild hepatic impairment. In non-nmCRPC individuals with severe renal impairment not on dialysis, exposure to darolutamide was increased by about 2.5-fold relative to healthy people. In non-nmCRPC individuals with moderate hepatic impairment, darolutamide exposure was increased by about 1.9-fold compared to healthy controls. The pharmacokinetics of darolutamide have not been assessed in end-stage kidney disease or severe hepatic impairment. Chemistry
Darolutamide is a nonsteroidal compound and is structurally distinct from other marketed NSAAs, including enzalutamide and apalutamide. History
Darolutamide was developed by Orion Corporation and Bayer HealthCare.
Darolutamide was associated with greater benefits than placebo for all secondary end points, including overall survival (hazard ratio 0.69; 95% CI: 0.53-0.88; P=0.003), time to pain progression (median 40.3 months vs. 25.4 months; hazard ratio 0.65; 95% CI: 0.53-0.79; P<0.001), time to cytotoxic chemotherapy (hazard ratio 0.43; 95% CI: 0.31-0.60), and time to a symptomatic skeletal event (hazard ratio 0.43; 95% CI: 0.22-0.84).

Darolutamide monotherapy is being studied in comparison to androgen deprivation therapy with GnRH agonist or antagonist monotherapy in men with treatment-naive prostate cancer. As of 2018, it is entering a phase II clinical trial for this indication. This study is expected for completion in 2021 or 2022.Darolutamide is being studied for the treatment of breast cancer in women. As of November 2019, it is in phase II clinical trials for this indication. References
