Special Patient Groups
Pregnancy
Erleada is not indicated for use in women. It can cause fetal harm when administered to a pregnant woman. Based on its mechanism of action and animal studies, apalutamide may cause adverse developmental effects. Male patients with female partners of reproductive potential should use effective contraception during treatment and for 3 months after the last dose.
Trimester-Specific Risks:
Lactation
Erleada is not indicated for use in women. It is unknown if apalutamide or its metabolites are excreted in human milk. Due to the potential for serious adverse reactions in a breastfed infant, Erleada should not be used by lactating women.
Pediatric Use
The safety and efficacy of Erleada in pediatric patients have not been established. Erleada is not indicated for use in pediatric patients.
Geriatric Use
No dose adjustment is required for geriatric patients. Of the total number of patients in clinical studies of Erleada, 75% were 65 years and older, and 33% were 75 years and older. No overall differences in safety or effectiveness were observed between these subjects and younger subjects. However, geriatric patients may be more susceptible to certain adverse reactions such as falls and fractures.
Clinical Information
Clinical Pearls
- Apalutamide is an oral medication that must be taken consistently once daily. Emphasize adherence to patients.
- Patients must continue concomitant GnRH analog therapy or have had a bilateral orchiectomy.
- Counsel patients on the importance of reporting any new neurological symptoms, especially seizures, or severe skin reactions immediately.
- Monitor for and manage cardiovascular risk factors, including hypertension, diabetes, and dyslipidemia, as these can be exacerbated.
- Be aware of significant drug-drug interactions, particularly with CYP3A4, CYP2C9, and CYP2C19 substrates, and P-gp/BCRP/OATP1B1/1B3 substrates. Review patient's concomitant medications carefully.
- Patients should be advised about the risk of falls and fractures; consider bone health assessment and management.
- Hypothyroidism has been reported; monitor thyroid function if clinically indicated.
