STUDY DESIGN
ARAMIS IS THE LARGEST PHASE III
STUDY IN nmCRPC TO DATE1-3
Double-blind, placebo-controlled, international, multicenter study1,4
- Men with prior seizure or conditions predisposing to seizure were allowed in the study
- Treatment continued until radiographic disease progression as assessed by conventional imaging (CT, MRI, 99mTc bone scan) by blinded independent central review, discontinuation due to adverse reactions, or withdrawal of consent
PRIMARY ENDPOINT
- Metastasis-free survival (MFS)
SECONDARY ENDPOINTS
- Overall survival (OS)
- Time to pain progression‡
- Time to first cytotoxic chemotherapy
- Time to first symptomatic skeletal event
EXPLORATORY ENDPOINTS
- Progression-free survival
- Time to first prostate cancer–related procedure
- Time to initiation of subsequent chemotherapy
- PSA progression and response
- Deterioration in ECOG PS
- Quality of life§
*All patients received concurrent ADT (treatment with GnRH analog or previous bilateral orchiectomy).
†Lymph nodes located below the aortic bifurcation as measured by the short axis.
‡Time to pain progression was defined as at least a 2-point worsening from baseline of the pain score on Brief Pain Inventory–Short Form or initiation of opioids, in patients treated with NUBEQA as compared to placebo. Pain progression was reported in 28% of patients on study.
§Tools used to prespecify quality of life exploratory endpoints are the EQ-5D-3L, a preference-based instrument, and the FACT-P, BPI-SF, and EORTC-QLQ-PR25 prostate-specific questionnaires.
CRPC=castration-resistant prostate cancer; PSADT=PSA doubling time; PSA=prostate-specific antigen; ECOG PS=Eastern Cooperative Oncology Group performance status; CT=computed tomography; GnRH=gonadotropin-releasing hormone.
Well-balanced study arms in ARAMIS4
- ECOG PS performance status is graded according to the following criteria: 0: Fully active, able to carry on all pre-disease performance without restriction; 1: Restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature, eg, light house work, office work5
- Bone-sparing agents included bisphosphonates, denosumab, vitamin D and analogs, calcium and calcium combinations, fluorides, and calcitonins6
- Common previous hormonal therapies for prostate cancer (received by ≥10% of all patients) included leuprolide (52%), goserelin (32%), triptorelin (29%), bicalutamide (66%), flutamide (13%), and cyproterone (11%)4
IMPORTANT SAFETY INFORMATION (cont’d)
Adverse Reactions
Serious adverse reactions occurred in 25% of patients receiving NUBEQA and in 20% of patients receiving placebo. Serious adverse reactions in ≥ 1 % of patients who received NUBEQA were urinary retention, pneumonia, and hematuria. Overall, 3.9% of patients receiving NUBEQA and 3.2% of patients receiving placebo died from adverse reactions, which included death (0.4%), cardiac failure (0.3%), cardiac arrest (0.2%), general physical health deterioration (0.2%), and pulmonary embolism (0.2%) for NUBEQA.
Please see additional Important Safety Information below.
EFFICACY
40 MONTHS MFS ACHIEVED with
NUBEQA + ADT1,4
Significant increase in median MFS vs ADT alone
- MFS results were consistent across patient subgroups for1:
- PSA doubling time (≤6 months or >6 months)
- Prior use of bone-targeting agents (yes or no)
*95% CI: 34.3-NR.
†95% CI: 15.5-22.3.
MFS=metastasis-free survival; ADT=androgen-deprivation therapy; PSA=prostate-specific antigen; HR=hazard ratio; CI=confidence interval; NR=not reached.
PSA response
• NUBEQA exposure at 600 mg twice daily results in PSA mean reduction of more than 90% from baseline1
Prespecified secondary endpoints1,4
- The MFS result was supported by a delay in time to pain progression, defined as at least a 2-point worsening from baseline of the pain score on Brief Pain Inventory-Short Form or initiation of opioids, in men treated with NUBEQA + ADT as compared to ADT alone. Pain progression was reported in 28% of all men on study
- OS data were not mature at the time of MFS analysis (57% of the required number of events). Secondary endpoints were evaluated in a hierarchical order, with a significance level of 0.05 split between the primary analysis and the final analysis (planned to occur after 240 deaths from any cause) of secondary endpoints. The endpoint OS was used to determine the alpha spend and significance threshold for each of the secondary endpoints. This prevented the significance criteria from being met in all secondary endpoints at the interim analysis
- The planned final analysis has been conducted and mature data on OS and other secondary endpoints will be presented at an upcoming scientific meeting

Two 300 mg tablets administered twice daily with food for a total daily dose of 1200 mg
- Swallow tablets whole with food
- Patients should also receive a GnRH analog concurrently or have had a bilateral orchiectomy
- Advise patients to take a missed dose when they remember prior to the next scheduled dose, and not to take two doses together to make up for a missed dose

Modify dose to 300 mg twice daily in patients with1:
- Severe renal impairment (eGFR 15-29 mL/min/1.73 m2) not receiving hemodialysis
- Moderate hepatic impairment (Child-Pugh Class B)
- Grade ≥3 toxicity or an intolerable adverse reaction
- Withhold dose or reduce to 300 mg twice daily until symptoms improve. Then increase to 600 mg twice daily
- Dosage below 300 mg twice daily is not recommended
Limited drug-drug interactions (DDIs) and no contraindications1,7
DDIs with concomitant use of NUBEQA1,7,8
*Decreases darolutamide exposure, which may decrease NUBEQA activity.
†Increases darolutamide exposure, which may increase the risk of NUBEQA adverse reactions.
‡Increases BCRP substrate exposure, which may increase the risk of related toxicities. Consult the approved product labeling of the BCRP substrate when used concomitantly with NUBEQA.

PRECLINICAL
PRECLINICAL STUDIES OF MOA AND
BLOOD-BRAIN PENETRATION
NUBEQA inhibits androgen receptor (AR) function1
• NUBEQA inhibited transcriptional activity in vitro (IC50 65nM)10
Preclinical analysis of blood-brain penetration with NUBEQA4,11,12
- The brain-to-plasma ratio of NUBEQA in mice was low at 3%
- Based on these data, men with a history of seizure were allowed in ARAMIS
- However, the penetration of NUBEQA across the human blood-brain barrier has not been studied
Low blood-brain penetration in preclinical studies11,12

INDICATION
NUBEQA® (darolutamide) is an androgen receptor inhibitor indicated for the treatment of patients with non-metastatic castration-resistant prostate cancer.
IMPORTANT SAFETY INFORMATION
Embryo-Fetal Toxicity: Safety and efficacy of NUBEQA have not been established in females. NUBEQA can cause fetal harm and loss of pregnancy. Advise males with female partners of reproductive potential to use effective contraception during treatment with NUBEQA and for 1 week after the last dose.
Adverse Reactions
Serious adverse reactions occurred in 25% of patients receiving NUBEQA and in 20% of patients receiving placebo. Serious adverse reactions in ≥ 1 % of patients who received NUBEQA were urinary retention, pneumonia, and hematuria. Overall, 3.9% of patients receiving NUBEQA and 3.2% of patients receiving placebo died from adverse reactions, which included death (0.4%), cardiac failure (0.3%), cardiac arrest (0.2%), general physical health deterioration (0.2%), and pulmonary embolism (0.2%) for NUBEQA.
Adverse reactions occurring more frequently in the NUBEQA arm (≥2% over placebo) were fatigue (16% vs. 11%), pain in extremity (6% vs. 3%) and rash (3% vs. 1%).
Clinically significant adverse reactions occurring in ≥ 2% of patients treated with NUBEQA included ischemic heart disease (4.0% vs. 3.4% on placebo) and heart failure (2.1% vs. 0.9% on placebo).
Drug Interactions
Effect of Other Drugs on NUBEQA – Concomitant use of NUBEQA with a combined P-gp and strong or moderate CYP3A4 inducer decreases darolutamide exposure, which may decrease NUBEQA activity. Avoid concomitant use of NUBEQA with combined P-gp and strong or moderate CYP3A4 inducers.
Concomitant use of NUBEQA with a combined P-gp and strong CYP3A4 inhibitor increases darolutamide exposure, which may increase the risk of NUBEQA adverse reactions. Monitor patients more frequently for NUBEQA adverse reactions and modify NUBEQA dosage as needed.
Effects of NUBEQA on Other Drugs – NUBEQA is an inhibitor of breast cancer resistance protein (BCRP) transporter. Concomitant use of NUBEQA increases the exposure (AUC) and maximal concentration of BCRP substrates, which may increase the risk of BCRP substrate-related toxicities. Avoid concomitant use with drugs that are BCRP substrates where possible. If used together, monitor patients more frequently for adverse reactions, and consider dose reduction of the BCRP substrate drug. Consult the approved product labeling of the BCRP substrate when used concomitantly with NUBEQA.
