NUBEQA (darolutamide) Safety and Side Effects: Tolerability
- NUBEQA (darolutamide) safety and tolerability is well-documented across three clinical trials: ARANOTE, ARASENS, and ARAMIS, and supports its suitability for a wide range of mHSPC and nmCRPC patient populations.
- NUBEQA offers a distinct molecular structure, reduced blood–brain barrier penetration* and fewer drug–drug interactions versus other second-generation ARIs.
- NUBEQA’s proven tolerability, helps patients continue treatment without further impacting their QoL and daily routines.
* Versus apalutamide and enzalutamide in a preclinical model.


NUBEQA (darolutamide) Side effects and Safety: ARANOTE Study
- The ARANOTE Phase III clinical trial investigated the efficacy and safety of NUBEQA in combination with ADT in metastatic hormone-sensitive prostate cancer (mHSPC) patients.
- Patients randomised in a 2:1 ratio (N=669) were administered either NUBEQA + ADT doublet therapy (n=446) or placebo + ADT (n=223), with a primary endpoint of radiographic progression-free survival.
- The well-established and consistent NUBEQA safety profile was demonstrated in ARANOTE, adding to the body of evidence from ARASENS (mHSPC) and ARAMIS (nmCRPC) clinical trials.

ARANOTE: Occurrence of Adverse Events (AEs) with NUBEQA + ADT vs Placebo + ADT
Most adverse events were grade 1 and 2, with no significant differences in grade 3, 4, and 5 adverse events in the treatment groups.
a : Two patients who were randomly assigned to the placebo group but received NUBEQA are analysed in the NUBEQA group for the safety analysis set.

Maintain your patients’ QoL with NUBEQA
The only second-generation ARI in mHSPC with lower levels of fatigue and fewer discontinuations versus placebo when added to ADT in a Phase III clinical trial.
ARANOTE: AEs of special interest common to the ARI class
- In ARANOTE, burdensome adverse events commonly associated with second-generation ARIs, including rash, occurred at low or similar incidences in the NUBEQA + ADT and placebo + ADT groups.
- NUBEQA is the only second-generation ARI with lower rate of fatigue when added to ADT versus placebo + ADT in a Phase III clinical trial (5.6% vs 8.1%).

- Ischaemic heart diseaseexpand_moreIschaemic heart disease:
- Ischaemic heart disease, including fatal cases, occurred in patients receiving NUBEQA in the clinical studies ARAMIS and ARASENS.
- Monitor for signs and symptoms of ischaemic heart disease. Optimise management of cardiovascular risk factors, such as hypertension, diabetes, or dyslipidaemia.
- Discontinue NUBEQA for Grade 3-4 ischaemic heart disease.
- Seizureexpand_moreSeizure:
- Seizure occurred in patients receiving NUBEQA in the clinical studies ARAMIS and ARASENS. It is unknown whether anti-epileptic medications will prevent seizures with NUBEQA.
- Advise patients of the risk of developing a seizure while receiving NUBEQA and of engaging in any activity where sudden loss of consciousness could cause harm to themselves or others.
- Consider discontinuation of NUBEQA in patients who develop a seizure during treatment.
- Hepatotoxicityexpand_moreHepatotoxicity:
- Cases of idiosyncratic drug-induced liver injury (DILI) with increases in alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) to ≥5 and ≥20 x upper limit of normal (ULN) have been reported in NUBEQA clinical trials and post-marketing settings.
- In case of liver function test abnormalities suggestive of idiosyncratic drug-induced liver injury, permanently discontinue NUBEQA.
- Renal impairmentexpand_moreRenal impairment:
- Available data in patients with severe renal impairment are limited, therefore, patients with renal impairment should be closely monitored for adverse reactions.
- Hepatic impairmentexpand_moreHepatic impairment:
- Available data in patients with moderate hepatic impairment is limited, and NUBEQA has not been studied in patients with severe hepatic impairment.
- Therefore, due to potential increased exposure, such patients should be closely monitored for adverse reactions.
- Recent cardiovascular diseaseexpand_moreRecent cardiovascular disease:
- Safety of NUBEQA in patients with significant cardiovascular disease in the past six months is not established, as these patients were excluded from clinical studies.
- If NUBEQA is prescribed, patients with clinically significant cardiovascular disease should be treated for these conditions according to established guidelines.
- Drug-drug interactions (DDIs): Concomitant use with other medicinal products expand_moreDrug-drug interactions (DDIs): Concomitant use with other medicinal products:
Prostate cancer patients are often managing multiple comorbidities and complex polypharmacy.
NUBEQA interacts with fewer medications versus other second-generation ARIs, offering confidence when treating patients who required concomitant medications
Number of medicines listed as an interaction in the BNF (as of August 2025)- DDIs may cause treatment and/or management complexities, such as: Reduced efficacy of ARI and other prescribed medications; dose adjustment, discontinuation or switching; increased risk, incidence and severity of AEs; increased stress, confusion and anxiety for patients and caregivers; and increased healthcare burden
- Use of strong CYP3A4 and P‑gp inducers during treatment with NUBEQA may decrease the plasma concentration of NUBEQA and is not recommended, unless there is no therapeutic alternative.
- Patients should be monitored for adverse reactions of BCRP, OATP1B1 and OATP1B3 substrates as co‑administration with NUBEQA may increase the plasma concentrations of these substrates.
- Co‑administration of NUBEQA and rosuvastatin should be avoided unless there is no therapeutic alternative.
Deepen your learning of second-generation ARI DDIs: - ADT may prolong the QT intervalexpand_moreADT may prolong the QT interval:
- In patients with a history of risk factors for QT prolongation and in patients receiving concomitant medicinal products that might prolong the QT interval, physicians should assess the benefit‑risk ratio including the potential for Torsade de pointes prior to initiating NUBEQA.
NUBEQA (darolutamide): fertility, pregnancy and breastfeeding
NUBEQA is not indicated in women of childbearing potential and is not to be used in women who are, or may be, pregnant or breastfeeding.

Fertility
- There are no human data on the effect of NUBEQA on fertility.
- Based on animal studies, NUBEQA may impair fertility in males of reproductive potential.
- It is not known whether NUBEQA or its metabolites are present in semen.
- If the patient is engaged in sexual activity with a women of childbearing potential, a highly effective contraception method (<1% failure rate per year) should be used during and for 1 week after completion of treatment with NUBEQA to prevent pregnancy.

Pregnancy
- Based on its mechanism of action, NUBEQA may cause foetal harm. No non-clinical reproductive toxicity studies have been conducted.
- Exposure of the foetus to an androgen receptor inhibitor through seminal transfer to the pregnant women has to be avoided, as this could affect development of the foetus.
- If the patient is engaged in sexual activity with a pregnant woman, a condom should be used during and for 1 week after completion of treatment with NUBEQA.

Breastfeeding
- It is unknown whether darolutamide or its metabolites are excreted in human milk. No studies in animals have been conducted to evaluate the excretion of darolutamide or its metabolites into milk. A risk to the breastfed child cannot be excluded.
