Nubeqa Drug Information

is an androgen receptor inhibitor indicated for the treatment of adult patients with: non-metastatic castration-resistant prostate cancer (nmCRPC). metastatic castration-sensitive prostate cancer (mCSPC). metastatic castration-sensitive prostate cancer (mCSPC) in combination with docetaxel. NUBEQA is indicated for the treatment of adult patients with: non-metastatic castration resistant prostate cancer (nmCRPC) metastatic castration-sensitive prostate cancer (mCSPC) metastatic castration-sensitive prostate cancer (mCSPC) in combination with docetaxel.

Recommended Dosage

The recommended dose of NUBEQA is 600 mg (two 300 mg tablets) taken orally, twice daily, with food. Continue treatment until disease progression or unacceptable toxicity occurs. Patients receiving NUBEQA should also receive a gonadotropin-releasing hormone (GnRH) agonist or antagonist concurrently or have had a bilateral orchiectomy.

When used in combination with docetaxel for mCSPC, administer the first of 6 cycles of docetaxel within 6 weeks after the start of NUBEQA treatment. Refer to docetaxel prescribing information for additional dosing information, including dosage modifications. Treatment with NUBEQA may be continued until disease progression or unacceptable toxicity, even if a cycle of docetaxel is delayed, interrupted, or discontinued . Advise patients to swallow tablets whole with food, 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 or an intolerable adverse reaction, withhold NUBEQA or reduce dosage to 300 mg twice daily until symptoms improve. NUBEQA may be resumed at a dose of 600 mg twice daily, when adverse reaction returns to baseline. Dosage reduction below 300 mg twice daily is not recommended.

For patients who experience ischemic heart disease or seizure, additional dose modifications may be required.

Recommended Dosage in Patients with Severe Renal Impairment For patients with severe

renal impairment (eGFR 15–29 mL/min/1.73 m 2 ) not receiving hemodialysis, the recommended dose of NUBEQA is 300 mg twice daily .

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 .

Clinical Trials Experience

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. The pooled data in WARNINGS and PRECAUTIONS reflect two randomized clinical trials in patients with nmCRPC (N = 954) and mCSPC (N = 445) treated with NUBEQA. In these trials, the median duration of treatment was 18.2 months (range 0.03 to 44.3) for patients who received NUBEQA. In this pooled safety population, the most common adverse reactions (>10% with a ≥2% increase over placebo), including laboratory test abnormalities were increased AST, decreased neutrophil count, increased bilirubin, fatigue and increased ALT. The safety of NUBEQA in combination with docetaxel in mCSPC is based on data from 1302 patients of whom 652 received at least one dose of NUBEQA in the ARASENS study. Non-Metastatic Castration Resistant Prostate Cancer ARAMIS The safety of NUBEQA in nmCRPC patients was evaluated in ARAMIS, a randomized (2:1), double-blind, placebo-controlled, multi-center clinical 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. Among patients who received NUBEQA, the median duration of exposure was 14.8 months (range: 0 to 44.3 months). 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.

Fatal adverse reactions occurred in 3.9% of patients receiving NUBEQA and 3.2% of patients receiving placebo. Fatal adverse reactions that occurred in ≥2 patients who received NUBEQA included death (0.4%), cardiac failure (0.3%), cardiac arrest (0.2%), general physical health deterioration (0.2%), and pulmonary embolism (0.2%). Permanent discontinuation of NUBEQA due to adverse reactions occurred in 9% of patients receiving NUBEQA. The most common 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 common 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 common adverse reactions requiring dosage reduction in patients treated with NUBEQA included fatigue (0.7%), hypertension (0.3%), and nausea (0.3%). The most common (>2% with a ≥2% increase compared to placebo) adverse reactions, including laboratory test abnormalities, were increased AST, decreased neutrophil count, fatigue, increased bilirubin, pain in extremity, and rash.

The safety of NUBEQA, in combination with docetaxel, in mCSPC patients was evaluated in ARASENS, a randomized (1:1), double-blind, placebo-controlled, multi-center clinical study . Patients were to receive either NUBEQA at a dose of 600 mg, or a placebo, twice a day in combination with docetaxel at a dose of 75 mg/m2 every 21 days for 6 cycles. All patients in the ARASENS study received a concomitant gonadotropin-releasing hormone (GnRH) agonist or antagonist or had a bilateral orchiectomy.

Effects 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 . Avoid concomitant use of NUBEQA with 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 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 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 C max 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. 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 , Review the prescribing information of the BCRP, OATP1B1 and OATP1B3 substrates when used concomitantly with NUBEQA.

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. Animal embryo-fetal developmental toxicology studies were not conducted with darolutamide.

There are no human data on the use of NUBEQA in pregnant females.

Pediatric Use Safety and effectiveness of NUBEQA in pediatric patients have not been established.

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 . 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.
