Warnings and Precautions, Interstitial Lung Disease (ILD) (5.6 Interstitial Lung Disease (ILD)/PneumonitisFatal and life-threatening interstitial lung disease (ILD) or pneumonitis can occur in patients treated with ERLEADA. Post-marketing cases of ILD/pneumonitis, including fatal cases, occurred in patients treated with ERLEADA. Across clinical trials (TITAN and SPARTAN, n=1327), 0.8% of patients treated with ERLEADA experienced ILD/pneumonitis, including 0.2% who experienced Grade 3 events [see Adverse Reactions (6.1, 6.2)]. Monitor patients for new or worsening symptoms indicative of ILD/pneumonitis (e.g., dyspnea, cough, fever). Immediately withhold ERLEADA if ILD/pneumonitis is suspected. Permanently discontinue ERLEADA in patients with severe ILD/pneumonitis or if no other potential causes of ILD/pneumonitis are identified [see Dosage and Administration (2.2)] . | 8/2024 |

- Add 2 tablespoons (30 mL) of either orange juice, applesauce, or additional water and stir the mixture.
- Swallow the mixture immediately.
- Rinse the cup with enough water to make sure the whole dose is taken and drink it immediately.
- For one 240 mg tablet:Place the tablet in the barrel of the syringe (use at least a 20 mL syringe) and draw up 10 mL of non-carbonated water into the syringe.For 60 mg tablets (prescribed dose of 240 mg, 180 mg, or 120 mg):Place the entire prescribed dose of ERLEADA tablets in the barrel of the syringe (use at least a 50 mL syringe) and draw up 20 mL of non-carbonated water into the syringe.
- Wait 10 minutes and then shake vigorously to disperse contents completely.
- Administer immediately through the feeding tube.
- Refill the syringe with non-carbonated water and administer. Repeat until no tablet residue is left in the syringe or feeding tube.

The safety and efficacy of ERLEADA have not been established in females. Based on findings from animals and its mechanism of action, ERLEADA can cause fetal harm and loss of pregnancy when administered to a pregnant female
12.1 Mechanism of ActionApalutamide is an Androgen Receptor (AR) inhibitor that binds directly to the ligand-binding domain of the AR. Apalutamide inhibits AR nuclear translocation, inhibits DNA binding, and impedes AR-mediated transcription. A major metabolite, N-desmethyl apalutamide, is a less potent inhibitor of AR, and exhibited one-third the activity of apalutamide in an
In a pilot embryo-fetal developmental toxicity study in rats, apalutamide caused developmental toxicity when administered at oral doses of 25, 50 or 100 mg/kg/day throughout and after the period of organogenesis (gestational days 6–20). Findings included embryo-fetal lethality (resorptions) at doses ≥50 mg/kg/day, decreased fetal anogenital distance, misshapen pituitary gland, and skeletal variations (unossified phalanges, supernumerary short thoracolumbar rib(s), and small, incomplete ossification, and/or misshapen hyoid bone) at ≥25 mg/kg/day. A dose of 100 mg/kg/day caused maternal toxicity. The doses tested in rats resulted in systemic exposures (AUC) approximately 2, 4 and 6 times, respectively, the AUC in patients.
