Indications and Usage for Nubeqa

Nubeqa is indicated for the treatment of patients with non-metastatic castration resistant prostate cancer (nmCRPC).

Nubeqa Dosage and Administration

Recommended Dosage

The recommended dose of Nubeqa is 600 mg (two 300 mg film-coated tablets) taken orally, twice daily, equivalent to a total daily dose of 1200 mg. Swallow tablets whole with food [see Clinical Pharmacology (12.3)].

Patients receiving Nubeqa should also receive a gonadotropin-releasing hormone (GnRH) analog concurrently or should have had a bilateral orchiectomy.

Advise patients to take any missed dose as soon as they remember prior to the next scheduled dose, and not to take two doses together to make up for a missed dose.

Dosage Modification

If a patient experiences a greater than or equal to Grade 3 toxicity or an intolerable adverse reaction, withhold dosing or reduce to 300 mg twice daily until symptoms improve. Then the treatment may be resumed at a dose of 600 mg twice daily.

Dose reduction below 300 mg twice daily is not recommended.

Recommended Dosage in Patients with Severe Renal Impairment

For patients with severe renal impairment (eGFR 15–29 mL/min/1.73 m2) not receiving hemodialysis, the recommended dose of Nubeqa is 300 mg twice daily [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)].

Recommended Dosage in Patients with Moderate Hepatic Impairment

For patients with moderate hepatic impairment (Child-Pugh Class B), the recommended dose of Nubeqa is 300 mg twice daily [see Use in Specific Populations (8.7) and Clinical Pharmacology (12.3)].

Dosage Forms and Strengths

Tablets (300 mg): white to off-white oval film-coated tablets marked with “300” on one side and “Bayer” on the other.

Contraindications

None.

Warnings and Precautions

Embryo-Fetal Toxicity

The safety and efficacy of Nubeqa have not been established in females. Based on its mechanism of action, Nubeqa can cause fetal harm and loss of pregnancy when administered to a pregnant female [see Clinical Pharmacology (12.1)].

Advise males with female partners of reproductive potential to use effective contraception during treatment and for 1 week after the last dose of Nubeqa [see Use in Specific Populations (8.1, 8.3)].

Adverse Reactions

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

ARAMIS, a randomized (2:1), double-blind, placebo-controlled, multi-center clinical study, enrolled patients who had non-metastatic, castration-resistant prostate cancer (nmCRPC). In this study, patients received either Nubeqa at a dose of 600 mg, or a placebo, twice a day. All patients in the ARAMIS study received a concomitant gonadotropin-releasing hormone (GnRH) analog or had a bilateral orchiectomy. The median duration of exposure was 14.8 months (range: 0 to 44.3 months) in patients who received Nubeqa.

Overall, 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 included 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.

Permanent discontinuation due to adverse reactions occurred in 9% of patients receiving Nubeqa or placebo. The most frequent adverse reactions requiring permanent discontinuation in patients who received Nubeqa included cardiac failure (0.4%), and death (0.4%).

Dosage interruptions due to adverse reactions occurred in 13% of patients treated with Nubeqa. The most frequent adverse reactions requiring dosage interruption in patients who received Nubeqa included hypertension (0.6%), diarrhea (0.5%), and pneumonia (0.5%).

Dosage reductions due to adverse reactions occurred in 6% of patients treated with Nubeqa. The most frequent adverse reactions requiring dosage reduction in patients treated with Nubeqa included fatigue (0.7%), hypertension (0.3%), and nausea (0.3%).

Table 1 shows adverse reactions in ARAMIS reported in the Nubeqa arm with a ≥2% absolute increase in frequency compared to placebo. Table 2 shows laboratory test abnormalities related to Nubeqa treatment and reported more frequently in Nubeqa-treated patients compared to placebo-treated patients in the ARAMIS study.

Additionally, clinically significant adverse reactions occurring in 2% or more of patients treated with Nubeqa included ischemic heart disease (4.0% versus 3.4% on placebo) and heart failure (2.1% versus 0.9% on placebo).

Drug Interactions

Effect of Other Drugs on Nubeqa

Combined P-gp and Strong or Moderate CYP3A4 Inducer

Concomitant use of Nubeqa with a combined P-gp and strong or moderate CYP3A4 inducer decreases darolutamide exposure which may decrease Nubeqa activity [see Clinical Pharmacology (12.3)]. Avoid concomitant use of Nubeqa with clinical combined P-gp and strong or moderate CYP3A4 inducers.

Combined P-gp and Strong CYP3A4 Inhibitors

Concomitant use of Nubeqa with a combined P-gp and strong CYP3A4 inhibitor increases darolutamide exposure [see Clinical Pharmacology (12.3)] which may increase the risk of Nubeqa adverse reactions. Monitor patients more frequently for Nubeqa adverse reactions and modify Nubeqa dosage as needed [see Dosage and Administration (2.2)].

Effects of Nubeqa on Other Drugs

Breast Cancer Resistance Protein (BCRP) and Organic Anion Transporting Polypeptides (OATP) 1B1 and 1B3 Substrates

Nubeqa is an inhibitor of BCRP transporter. Concomitant use of Nubeqa increases the AUC and Cmax of BCRP substrates [see Clinical Pharmacology (12.3)], 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.

Nubeqa is an inhibitor of OATP1B1 and OATP1B3 transporters. Concomitant use of Nubeqa may increase the plasma concentrations of OATP1B1 or OATP1B3 substrates. Monitor patients more frequently for adverse reactions of these drugs and consider dose reduction while patients are taking Nubeqa [see Clinical Pharmacology (12.3)],

Review the prescribing information of the BCRP, OATP1B1 and OATP1B3 substrates when used concomitantly with Nubeqa.

USE IN SPECIFIC POPULATIONS

Pregnancy

Risk Summary

The safety and efficacy of Nubeqa have not been established in females. Based on its mechanism of action, Nubeqa can cause fetal harm and loss of pregnancy [see Clinical Pharmacology (12.1)]. Animal embryo-fetal developmental toxicology studies were not conducted with darolutamide. There are no human data on the use of Nubeqa in pregnant females.

Lactation

Risk Summary

The safety and efficacy of Nubeqa have not been established in females. There are no data on the presence of darolutamide or its metabolites in human milk, the effect on the breastfed child, or the effect on milk production.

Females and Males of Reproductive Potential

Contraception

Males

Based on the mechanism of action, advise male patients with female partners of reproductive potential to use effective contraception during treatment and for 1 week after the last dose of Nubeqa [see Use in Specific Populations (8.1)].

Infertility

Males

Based on animal studies, Nubeqa may impair fertility in males of reproductive potential [see Nonclinical Toxicology (13.1)].

Pediatric Use

Safety and effectiveness of Nubeqa in pediatric patients have not been established.

Geriatric Use

Of the 954 patients who received Nubeqa in ARAMIS, 88% of patients were 65 years and over, and 49% were 75 years and over. No overall differences in safety or efficacy were observed between these patients and younger patients.

Renal Impairment

Patients with severe renal impairment (eGFR 15–29 mL/min/1.73 m2) who are not receiving hemodialysis have a higher exposure to Nubeqa and reduction of the dose is recommended [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3)]. No dose reduction is needed for patients with mild or moderate renal impairment (eGFR 30-89 mL/min/1.73 m2). The effect of end stage renal disease (eGFR ≤15 mL/min/1.73 m2) on darolutamide pharmacokinetics is unknown.

Hepatic Impairment

Patients with moderate hepatic impairment (Child-Pugh Class B) have a higher exposure to Nubeqa and reduction of the dose is recommended [see Dosage and Administration (2.4) and Clinical Pharmacology (12.3)]. No dose reduction is needed for patients with mild hepatic impairment. The effect of severe hepatic impairment (Child-Pugh C) on darolutamide pharmacokinetics is unknown.

Overdosage

There is no known specific antidote for darolutamide overdose. The highest dose of Nubeqa studied clinically was 900 mg twice daily, equivalent to a total daily dose of 1800 mg. No dose limiting toxicities were observed with this dose.

Considering the saturable absorption and the absence of evidence for acute toxicity, an intake of a higher than recommended dose of darolutamide is not expected to lead to systemic toxicity in patients with intact hepatic and renal function [see Clinical Pharmacology (12.3)].

In the event of intake of a higher than recommended dose in patients with severe renal impairment or moderate hepatic impairment, if there is suspicion of toxicity, interrupt Nubeqa treatment and undertake general supportive measures until clinical toxicity has been diminished or resolved. If there is no suspicion of toxicity, Nubeqa treatment can be continued with the next dose as scheduled.

Nubeqa Description

Nubeqa is an androgen receptor inhibitor. The chemical name is N-{(2S)-1-[3-(3-chloro-4-cyanophenyl)-1H-pyrazol-1-yl]propan-2-yl}-5-(1-hydroxyethyl)-1H-pyrazole-3-carboxamide.

The molecular weight is 398.85 and the molecular formula is C19H19Cl N6O2. The structural formula is:

Darolutamide is an optically active with a specific rotation value [α]20D= 72.2 o*mL/(dm*g), white to greyish- or yellowish white crystalline powder, that is soluble in tetrahydrofuran, but practically insoluble in aqueous medium. Darolutamide has a pKa of 11.75.

Nubeqa (darolutamide) is supplied as film-coated tablets containing 300 mg of darolutamide for oral use. The inactive ingredients of the tablet are: calcium hydrogen phosphate, croscarmellose sodium, lactose monohydrate, magnesium stearate, povidone K 30, hypromellose 15 cP, macrogol 3350, and titanium dioxide.

Nubeqa - Clinical Pharmacology

Mechanism of Action

Darolutamide is an androgen receptor (AR) inhibitor. Darolutamide competitively inhibits androgen binding, AR nuclear translocation, and AR-mediated transcription. A major metabolite, keto-darolutamide, exhibited similar in vitro activity to darolutamide. In addition, darolutamide functioned as a progesterone receptor (PR) antagonist in vitro (approximately 1% activity compared to AR). Darolutamide decreased prostate cancer cell proliferation in vitro and tumor volume in mouse xenograft models of prostate cancer.

Pharmacodynamics

Darolutamide exposure at 600 mg twice daily results in PSA mean reduction of more than 90% from baseline.

Cardiac Electrophysiology

The effect of darolutamide (600 mg twice daily) on the QTc interval was evaluated in a subgroup of 500 patients in the ARAMIS study. No large mean increase in QTc (i.e., > 20 ms) was detected.

Pharmacokinetics

Following administration of 600 mg twice daily, darolutamide mean (%CV) steady-state peak plasma concentration (Cmax) is 4.79 mg/L (30.9%) and area under the plasma concentration-time curve from time 0 to 12 hours (AUC12h) is 52.82 h•µg/mL (33.9%). Steady-state is reached 2–5 days after repeated dosing with food, with an approximate 2-fold accumulation.

The exposure (Cmax and AUC12) of the darolutamide and the active metabolite keto‑darolutamide increase in a nearly dose-proportional manner in the dose range of 100 to 700 mg (0.17 to 1.17 times the approved recommended dosage). No further increase in darolutamide exposure was observed at 900 mg twice daily (1.5 times the approved recommended dosage).

Absorption

Darolutamide Cmax is reached approximately 4 hours after administration of a single 600 mg oral dose.

The absolute bioavailability is approximately 30% following oral administration of a Nubeqa tablet containing 300 mg darolutamide under fasted conditions.

Food Effect

Bioavailability of darolutamide increased by 2.0 to 2.5‑fold when administered with food. A similar increase of exposure was observed for the active metabolite keto‑darolutamide.

Distribution

The apparent volume of distribution of darolutamide after intravenous administration is 119 L.

Protein binding is 92% for darolutamide and 99.8% for the active metabolite, keto‑darolutamide. Serum albumin is the main binding protein for darolutamide and keto-darolutamide.

Elimination

The effective half-life of darolutamide and keto‑darolutamide is approximately 20 hours in patients. The clearance (%CV) of darolutamide following intravenous administration is 116 mL/min (39.7%).

Metabolism

Darolutamide is primarily metabolized by CYP3A4, as well as by UGT1A9 and UGT1A1. Keto‑darolutamide total exposure in plasma is 1.7‑fold higher compared to darolutamide.

Excretion

After a single radiolabeled dose as an oral solution, a total of 63.4% of darolutamide‑related material is excreted in the urine (approximately 7% unchanged) and 32.4% (approximately 30% unchanged) in the feces. More than 95% of the dose was recovered within 7 days after administration.

Specific Populations

In nmCRPC patients, no clinically significant differences in the pharmacokinetics of darolutamide were observed based on age (48-95 years), race (White, Japanese, non-Japanese Asian, Black or African American), mild to moderate renal impairment (eGFR 30–89 mL/min/1.73m2), or mild hepatic impairment.

In non-cancer subjects with severe renal impairment (eGFR 15–29 mL/min/1.73 m2) not receiving dialysis or with moderate hepatic impairment (Child-Pugh Class B), Nubeqa exposure increased by about 2.5- and 1.9-fold, respectively, compared to healthy subjects.

The effect of end-stage renal disease (eGFR <15 mL/min/1.73 m2) or severe hepatic impairment (Child-Pugh C) on darolutamide pharmacokinetics has not been studied.

Drug Interaction Studies

Clinical Studies

Combined P-gp and Strong CYP3A4 Inducers

Concomitant use of rifampicin (a combined P-gp and strong CYP3A4 inducer) decreased mean darolutamide AUC0-72 by 72% and Cmax by 52%. The decrease of darolutamide exposure by moderate CYP3A4 inducers is expected to be in the range of 36% – 58%.

Combined P-gp and Strong CYP3A4 Inhibitors

Itraconazole (a strong combined CYP3A4 and P-gp inhibitor) increased mean darolutamide AUC0-72 by 1.7- and Cmax by 1.4-fold.

CYP3A4 substrates

Concomitant use of darolutamide decreased the mean AUC and Cmax of midazolam (CYP3A4 substrate) by 29% and 32%, respectively. No clinically relevant differences in the pharmacokinetics of midazolam were observed when used concomitantly with darolutamide.

BCRP, OATP1B1 and OATP1B3 Substrates

Concomitant use of darolutamide increased the mean AUC and Cmax of rosuvastatin (BCRP, OATP1B1 and OATP1B3 substrate) by approximately 5-fold.

P-gp Substrates

No clinically relevant differences in the pharmacokinetics of dabigatran (P-gp substrate) were observed when used concomitantly with darolutamide.

In Vitro Studies

In vitro, darolutamide did not inhibit the major CYP enzymes (CYP1A2, 2A6, 2B6, 2C8, 2C9, 2C19, 2D6, 2E1, and 3A4) or transporters (MRP2, BSEP, OATs, OCTs, MATEs, OATP2B1, and NTCP) at clinically relevant concentrations.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment of Fertility

Long-term animal studies to evaluate the carcinogenic potential of darolutamide have not been conducted.

Darolutamide was clastogenic in an in vitro chromosome aberration assay in human peripheral blood lymphocytes. Darolutamide did not induce mutations in the bacterial reverse mutation (Ames) assay and was not genotoxic in the in vivo combined bone marrow micronucleus assay and the Comet assay in the liver and duodenum of the rat.

Fertility studies in animals have not been conducted with darolutamide. In repeat-dose toxicity studies in male rats (up to 26 weeks) and dogs (up to 39 weeks), tubular dilatation of testes, hypospermia, and atrophy of seminal vesicles, testes, prostate gland and epididymides were observed at doses ≥ 100 mg/kg/day in rats (0.6 times the human exposure based on AUC) and ≥ 50 mg/kg/day in dogs (approximately 1 times the human exposure based on AUC).

Clinical Studies

ARAMIS (NCT02200614) was a multicenter, double-blind, placebo-controlled clinical trial in 1509 patients with non-metastatic castration resistant prostate cancer with a prostate-specific antigen doubling time (PSADT) of ≤ 10 months. Randomization was stratified by PSADT and use of bone-targeted therapy at study entry. Patients with pelvic lymph nodes less than 2 cm in short axis below the aortic bifurcation were allowed to enter the study. Patients with a history of seizures were not excluded. Absence or presence of metastasis was assessed by blinded independent central review (BICR). PSA results were not blinded and were not used for treatment discontinuation.

Patients were randomized 2:1 to receive either 600 mg darolutamide orally twice daily (n=955) or matching placebo (n=554). Treatment continued until radiographic disease progression as assessed by CT, MRI, 99mTc bone scan by BICR, unacceptable toxicity or withdrawal. All patients received a gonadotropin-releasing hormone (GnRH) analog concurrently or had a bilateral orchiectomy.

The following patient demographics and disease characteristics were balanced between treatment arms. The median age was 74 years (range 48–95) and 9% of patients were 85 years of age or older. The racial distribution was 79% White, 13% Asian, and 3% Black. A majority of patients (73%) had a Gleason score of 7 or higher at diagnosis. The median PSADT was 4.5 months. Forty-two percent of patients in both treatment arms had prior surgery or radiotherapy to the prostate. Eleven percent of patients had enlarged pelvic lymph nodes less than 2 cm at study entry. Six percent of patients were retrospectively identified by BICR as having metastases at baseline. Seventy-three percent of patients received prior treatment with an anti-androgen (bicalutamide or flutamide). All patients had an Eastern Cooperative Oncology Group Performance Status (ECOG PS) score of 0 or 1 at study entry. There were 12 patients enrolled on the Nubeqa arm with a history of seizure. At baseline, 47% of patients reported no pain on the Brief Pain Inventory-Short Form (a 7-day diary average of the daily worst pain item).

The major efficacy endpoint was metastasis free survival (MFS), defined as the time from randomization to the time of first evidence of BICR-confirmed distant metastasis or death from any cause within 33 weeks after the last evaluable scan, whichever occurred first. Distant metastasis was defined as new bone or soft tissue lesions or enlarged lymph nodes above the aortic bifurcation. Overall survival (OS), time to pain progression, and time to initiation of cytotoxic chemotherapy, were additional efficacy endpoints.

Treatment with Nubeqa resulted in a statistically significant improvement in MFS compared to placebo. At the protocol-specified final analysis of OS, treatment with Nubeqa resulted in a statistically significant improvement in OS compared to placebo. The final analysis of OS and time to initiation of cytotoxic chemotherapy was event-driven and conducted after 254 OS events had occurred. The efficacy results from ARAMIS are summarized in Table 3 and Figure 1.

MFS results were consistent across patient subgroups for PSADT (≤ 6 months or > 6 months) or prior use of bone-targeting agents (yes or no).

Treatment with Nubeqa resulted in a statistically significant delay in time to pain progression (HR = 0.65, 95% CI= 0.53, 0.79; p < 0.0001). 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 and reported in 28% of all patients on study.

Treatment with Nubeqa resulted in a statistically significant delay in the initiation of cytotoxic chemotherapy (HR = 0.58, 95% CI = 0.44, 0.76; p < 0.0001).
