DOSAGE AND ADMINISTRATION

Glenza 160 mg containing Enzalutamide (four 40 mg capsules) administered orally once daily. Swallow the capsules whole. It can be taken with or without food

Dose Modifications

If a patient experiences a ≥ Grade 3 toxicity or an intolerable side effect, withhold dosing for one week or until symptoms improve to ≤ Grade 2, then resume at the same or a reduced dose (120 mg or 80 mg), if warranted. Concomitant Strong CYP2C8 Inhibitors The concomitant use of strong CYP2C8 inhibitors should be avoided if possible. If patients must be co-administered a strong CYP2C8 inhibitor, reduce the GLENZA dose to 80 mg once daily. If co-administration of the strong inhibitor is discontinued, the GLENZA dose should be returned to the dose used prior to initiation of the strong CYP2C8 inhibitor [see Drug Interactions (7.1) and Clinical Pharmacology (12.3)].

3 DOSAGE FORMS AND STRENGTHS

GLENZA 40 mg capsules are white to off-white oblong soft gelatin capsules imprinted in black ink with MDV.

4 CONTRAINDICATIONS

Pregnancy GLENZA can cause fetal harm when administered to a pregnant woman based on its mechanism of action. GLENZA is not indicated for use in women. GLENZA is contraindicated in women who are or may become pregnant. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, apprise the patient of the potential hazard to the fetus and the potential risk for pregnancy loss [see Use in Specific Populations (8.1)].

5 WARNINGS AND PRECAUTIONS

5.1 Seizure In the randomized clinical trial, 7 of 800 (0.9%) patients treated with GLENZA 160 mg once daily experienced a seizure. No seizures occurred in patients treated with placebo. Seizures occurred from 31 to 603 days after initiation of GLENZA. Patients experiencing seizure were permanently discontinued from therapy and all seizures resolved. There is no clinical trial experience re-administering GLENZA to patients who experienced seizures. The safety of GLENZA in patients with predisposing factors for seizure is not known because these patients were excluded from the trial. These exclusion criteria included a history of seizure, underlying brain injury with loss of consciousness, transient ischemic attack within the past 12 months, cerebral vascular accident, brain metastases, brain arteriovenous malformation or the use of concomitant medications that may lower the seizure threshold. Because of the risk of seizure associated with GLENZA use, patients should be advised of the risk of engaging in any activity where sudden loss of consciousness could cause serious harm to themselves or others.

6 ADVERSE REACTIONS

The following is discussed in more detail in other sections of the labeling: · Seizure [see Warnings and Precautions (5.1)] 6.1 Clinical Trial 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. In the randomized clinical trial in patients with metastatic castration-resistant prostate cancer who had previously received docetaxel, patients received GLENZA 160 mg orally once daily (N = 800) or placebo (N = 399). The median duration of treatment was 8.3 months with GLENZA and 3.0 months with placebo. All patients continued androgen deprivation therapy. Patients were allowed, but not required, to take glucocorticoids. During the trial, 48% of patients on the GLENZA arm and 46% of patients on the placebo arm received glucocorticoids. All adverse events and laboratory abnormalities were graded using NCI CTCAE version 4. The most common adverse drug reactions (≥ 5%) reported in patients receiving GLENZA in the randomized clinical trial were asthenia/fatigue, back pain, diarrhea, arthralgia, hot flush, peripheral edema, musculoskeletal pain, headache, upper respiratory infection, muscular weakness, dizziness, insomnia, lower respiratory infection, spinal cord compression and cauda equina syndrome, hematuria, paresthesia, anxiety, and hypertension. Grade 3 and higher adverse reactions were reported among 47% of GLENZA-treated patients and 53% of placebo-treated patients. Discontinuations due to adverse events were reported for 16% of GLENZA-treated patients and 18% of placebo-treated patients. The most common adverse reaction leading to treatment discontinuation was seizure, which occurred in 0.9% of the GLENZA-treated patients compared to none (0%) of the placebo-treated patients. Table 1 shows adverse reactions reported in the randomized clinical trial that occurred at a ≥ 2% absolute increase in frequency in the GLENZA arm compared to the placebo arm. Table 1.

Laboratory Abnormalities In the randomized clinical trial, Grade 1-4 neutropenia occurred in 15% of patients on GLENZA (1% Grade 3-4) and in 6% of patients on placebo (no Grade 3-4). The incidence of Grade 1-4 thrombocytopenia was similar in both arms; 0.5% of patients on GLENZA and 1% on placebo experienced Grade 3-4 thrombocytopenia. Grade 1-4 elevations in ALT occurred in 10% of patients on GLENZA (0.3% Grade 3-4) and 18% of patients on placebo (0.5% Grade 3-4). Grade 1-4 elevations in bilirubin occurred in 3% of patients on GLENZA and 2% of patients on placebo. Infections In the randomized clinical trial, 1.0% of patients treated with GLENZA compared to 0.3% of patients on placebo died from infections or sepsis. Infection-related serious adverse events were reported in approximately 6% of the patients on both treatment arms. Falls and Fall-related Injuries In the randomized clinical trial, falls or injuries related to falls occurred in 4.6% of patients treated with GLENZA compared to 1.3% of patients on placebo. Falls were not associated with loss of consciousness or seizure. Fall-related injuries were more severe in patients treated with GLENZA and included non-pathologic fractures, joint injuries, and hematomas. Hallucinations In the randomized clinical trial, 1.6% of patients treated with GLENZA were reported to have Grade 1 or 2 hallucinations compared to 0.3% of patients on placebo. Of the patients with hallucinations, the majority were on opioid-containing medications at the time of the event. Hallucinations were visual, tactile, or undefined. Reference ID: 3183415

7 DRUG INTERACTIONS

7.1 Drugs that Inhibit or Induce CYP2C8 Co-administration of a strong CYP2C8 inhibitor (gemfibrozil) increased the composite area under the plasma concentration-time curve (AUC) of enzalutamide plus N-desmethyl enzalutamide in healthy volunteers. Co-administration of GLENZA with strong CYP2C8 inhibitors should be avoided if possible. If co-administration of GLENZA with a strong CYP2C8 inhibitor cannot be avoided, reduce the dose of GLENZA [see Dosage and Administration (2.2) and Clinical Pharmacology (12.3)]. The effects of CYP2C8 inducers on the pharmacokinetics of enzalutamide have not been evaluated in vivo. Co-administration of GLENZA with strong or moderate CYP2C8 inducers (e.g., rifampin) may alter the plasma exposure of GLENZA and should be avoided if possible. Selection of a concomitant medication with no or minimal CYP2C8 induction potential is recommended [see Clinical Pharmacology (12.3)].

7.2 Drugs that Inhibit or Induce

CYP3A4 Co-administration of a strong CYP3A4 inhibitor (itraconazole) increased the composite AUC of enzalutamide plus Ndesmethyl enzalutamide by 1.3 fold in healthy volunteers [see Clinical Pharmacology (12.3)]. The effects of CYP3A4 inducers on the pharmacokinetics of enzalutamide have not been evaluated in vivo. Co-administration of GLENZA with strong CYP3A4 inducers (e.g., carbamazepine, phenobarbital, phenytoin, rifabutin, rifampin, rifapentine) may decrease the plasma exposure of GLENZA and should be avoided if possible. Selection of a concomitant medication with no or minimal CYP3A4 induction potential is recommended. Moderate CYP3A4 inducers (e.g., bosentan, efavirenz, etravirine, modafinil, nafcillin) and St. John’s Wort may also reduce the plasma exposure of GLENZA and should be avoided if possible [see Clinical Pharmacology (12.3)].

7.3 Effect of GLENZA

on Drug Metabolizing Enzymes Enzalutamide is a strong CYP3A4 inducer and a moderate CYP2C9 and CYP2C19 inducer in humans. At steady state, GLENZA reduced the plasma exposure to midazolam (CYP3A4 substrate), warfarin (CYP2C9 substrate), and omeprazole (CYP2C19 substrate). Concomitant use of GLENZA with narrow therapeutic index drugs that are metabolized by CYP3A4 (e.g., alfentanil, cyclosporine, dihydroergotamine, ergotamine, fentanyl, pimozide, quinidine, sirolimus and tacrolimus), CYP2C9 (e.g., phenytoin, warfarin) and CYP2C19 (e.g., S-mephenytoin) should be avoided, as enzalutamide may decrease their exposure. If co-administration with warfarin cannot be avoided, conduct additional INR monitoring [see Clinical Pharmacology (12.3)].
