Darolutamide is a formulation containing an androgen receptor (AR) antagonist with potential antineoplastic activity. Darolutamide binds to ARs in target tissues; subsequently, inhibiting androgen-induced receptor activation and facilitating the formation of inactive complexes that cannot translocate to the nucleus. This prevents binding to and transcription of AR-responsive genes that regulate prostate cancer cell proliferation. This ultimately leads to an inhibition of growth in AR-expressing prostate cancer cells.

4 Drug and Medication Information
4.1 Drug Indication

This drug is indicated for the treatment of patients diagnosed with non-metastatic and castrate-resistant prostate cancer.


FDA Label


Nubeqa is indicated for the treatment of adult men with non metastatic castration resistant prostate cancer (nmCRPC) who are at risk of developing metastatic disease.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Darolutamide, through its downstream effects on cancer cell growth, treats castrate-resistant prostate cancer. It inhibits cancer cell growth and markedly lowers prostate specific antigen (PSA) levels through potent androgen receptor antagonism.


5.2 ATC Code

L02BB


L - Antineoplastic and immunomodulating agents

L02 - Endocrine therapy

L02B - Hormone antagonists and related agents

L02BB - Anti-androgens

L02BB06 - Darolutamide


5.3 Absorption, Distribution and Excretion

Absorption

Darolutamide is absorbed in the gastrointestinal tract. In the fasted state, peak concentrations are reached within 3-5 hours, and within 3-8 hours in the fed state. Median Tmax is between 3-6 hours.The average darolutamide steady-state peak plasma concentration after a 600 mg twice daily dose is approximately 4.79 mg/L. The Cmax is attained approximately 4 hours after administration of a single 600 mg oral dose. The AUC 0-12h is approximately 52.82 hg/mL. **Effects of food** The absolute bioavailability of darolutamide is approximately 30% after fasting and taking a single 300 mg dose. Steady-state concentrations are attained between 2 and 5 days after repeated administration with food. The bioavailability of darolutamide increases by 2.0 to 2.5 times when it is given with food.


Route of Elimination

In a pharmacokinetic study, a radiolabeled dose of darolutamide in an oral solution showed that 63.4% of darolutamide-related material was excreted in the urine (7% of which was unchanged drug) and 32.4% in the feces (with 30% unchanged drug).


Volume of Distribution

After intravenous administration, the apparent volume of distribution of darolutamide is about 119L.


Clearance

The clearance of darolutamide after an intravenous dose is 116 mL/min (39.7%).


5.4 Metabolism/Metabolites

Darolutamide is mainly metabolized by the CYP3A4 hepatic microsomal enzyme in addition to UGT1A9 and UGT1A1. The main active metabolite keto-darolutamide in found in the plasma at 2 times the concentration of darolutamide.


5.5 Biological Half-Life

The half-life of darolutamide and its active metabolite, keto-darolutamide is about 20 hours. A phase 1 study determined a terminal half life ranging between 10-15 hours.


5.6 Mechanism of Action

The actions of androgens on androgen receptors (AR) potentiate the growth and survival of prostate cancer cells. Darolutamide competitively inhibits androgens from binding to their receptors, inhibiting AR nuclear translocation, as well as AR-mediated transcription. The end result of these processes is a decrease in prostate cancer cell proliferation and tumor size. Its main metabolite, keto-darolutamide, shows similar pharmacological activity to the parent drug, darolutamide. Darolutamide has been found to bind more tightly to the AR receptor than [apalutamide] and [enzalutamide], which are other androgen receptor antagonists. Darolutamide can act as a progesterone receptor (PR) antagonist in the laboratory setting with approximately 1% activity when compared to its actions at the androgen receptor. The clinical relevance is not known at this time.
