    LYSODREN is indicated for the treatment of patients with inoperable, functional or nonfunctional, adrenal cortical carcinoma.

  • 2 DOSAGE AND ADMINISTRATION

    2.1 Recommended Dose

    The recommended initial dose of LYSODREN is 2 g to 6 g orally, in three or four divided doses per day. Increase doses incrementally to achieve a blood concentration of 14 to 20 mg/L, or as tolerated.

    LYSODREN is a cytotoxic drug. Follow applicable special handling and disposal procedures.

    2.2 Dose Modifications

    Adrenal Crisis in the Setting of Shock or Severe Trauma

    Discontinue LYSODREN until recovery [see Warnings and Precautions (5.1)].

    Central Nervous System (CNS) Toxicity

    Discontinue LYSODREN until symptoms resolve. Seven to 10 days after symptoms resolve, restart at a lower dose (for example, decrease by 500-1000 mg) [see Warnings and Precautions (5.2)].

  • 3 DOSAGE FORMS AND STRENGTHS

    500 mg white, round, biconvex, scored tablets, bisected on one side and impressed with “BL” over “L1” on the other side.

  • 4 CONTRAINDICATIONS

    None.

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Adrenal Crisis in the Setting of Shock or Severe Trauma

    In patients taking LYSODREN, adrenal crisis occurs in the setting of shock or severe trauma and response to shock is impaired. Administer hydrocortisone, monitor for escalating signs of shock, and discontinue LYSODREN until recovery [see Dosage and Administration (2.2)].

    5.2 CNS Toxicity

    CNS toxicity, including sedation, lethargy, and vertigo, occurs with LYSODREN treatment. Mitotane plasma concentrations exceeding 20 mcg/mL are associated with a greater incidence of toxicity.

    5.3 Adrenal Insufficiency

    Treatment with LYSODREN can cause adrenal insufficiency. Institute steroid replacement as clinically indicated. Measure free cortisol and corticotropin (ACTH) levels to achieve optimal steroid replacement.

    5.4 Embryo-Fetal Toxicity

    LYSODREN can cause fetal harm when administered to a pregnant woman. Abnormal pregnancy outcomes, such as preterm births and early pregnancy loss, can occur in patients exposed to mitotane during pregnancy. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with LYSODREN and after discontinuation of treatment for as long as mitotane plasma levels are detectable [see Use in Specific Populations (8.1, 8.3)].

    5.5 Ovarian Macrocysts in Premenopausal Women

    Ovarian macrocysts, often bilateral and multiple, have been reported in premenopausal patients receiving LYSODREN. Complications from these cysts, including adnexal torsion and hemorrhagic cyst rupture, have been reported. In some cases, improvement after mitotane discontinuation has been described. Advise female patients to seek medical care if they experience gynecological symptoms such as vaginal bleeding and/or pelvic pain [see Adverse Reactions (6)].

  • 6 ADVERSE REACTIONS

    The following adverse reactions are discussed in greater detail in other sections of the label:

    The following adverse reactions associated with the use of LYSODREN were identified in clinical trials or postmarketing reports. Because these reactions were reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency reliably or to establish a causal relationship to drug exposure.

    Common adverse reactions occurring with LYSODREN treatment include:

    • Anorexia, nausea, vomiting, and diarrhea (80%)
    • Depression, dizziness, or vertigo (15%-40%)
    • Rash (15%)
    • Neutropenia
    • Growth retardation, hypothyroidism
    • Confusion, headache, ataxia, mental impairment, weakness, dysarthria
    • Maculopathy
    • Hepatitis, elevation of liver enzymes
    • Gynecomastia
    • Hypercholesterolemia, hypertriglyceridemia
    • Decreased blood androstenedione and decreased blood testosterone in females, increased sex hormone binding globulin in females      and males, decreased blood free testosterone in males.

    Less common adverse reactions include: visual blurring, diplopia, lens opacity, retinopathy, prolonged bleeding time, hematuria, hemorrhagic cystitis, albuminuria, hypertension, orthostatic hypotension, flushing, generalized aching, and fever.

  • 7 DRUG INTERACTIONS

    7.1 CYP3A4 Substrates

    Mitotane is a strong inducer of cytochrome P450 3A4 (CYP3A4). Monitor patients for a change in dosage requirements for the concomitant drug when administering LYSODREN to patients receiving drugs that are substrates of CYP3A4.

    7.2 Warfarin

    When administering coumarin-type anticoagulants to patients receiving LYSODREN, monitor coagulation tests and adjust the anticoagulant dose as needed.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary

    LYSODREN can cause fetal harm. Limited postmarketing cases report preterm births and early pregnancy loss in women treated with LYSODREN during pregnancy. Animal reproduction studies have not been conducted with mitotane. Advise pregnant women of the potential risk to a fetus. The background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.

    8.2 Lactation

    Risk Summary

    Mitotane is excreted in human milk; however, the effect of LYSODREN on the breastfed infant, or effect on milk production is unknown. Because of the potential for serious adverse reactions in the breastfed infant, advise nursing women that breastfeeding is not recommended during treatment with LYSODREN and after discontinuation of treatment for as long as mitotane plasma levels are detectable.

    8.3 Females and Males of Reproductive Potential

    Contraception

    Females

    LYSODREN can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)]. Advise female patients of reproductive potential to use effective contraception during treatment with LYSODREN and after discontinuation of therapy for as long as mitotane plasma levels are detectable [see Clinical Pharmacology (12.3)].

    8.4 Pediatric Use

    Safety and effectiveness in pediatric patients have not been established.

    8.5 Geriatric Use

    Clinical studies of LYSODREN did not include sufficient numbers of patients aged 65 years and older to determine whether they respond differently than younger patients. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

    8.6 Hepatic Impairment

    Hepatic impairment may interfere with the metabolism of mitotane and the drug may accumulate. Administer LYSODREN with caution to patients with hepatic impairment.

  • 11 DESCRIPTION

    Image Mitotane Chemical Structure

    Mitotane is a white granular solid composed of clear colorless crystals. It is tasteless and has a slight pleasant aromatic odor. It is soluble in ethanol and has a molecular weight of 320.05.

    Inactive ingredients in LYSODREN are: microcrystalline cellulose, polyethylene glycol 3350, silicon dioxide, and starch.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Mitotane is an adrenal cytotoxic agent with an unknown mechanism of action. Mitotane modifies the peripheral metabolism of steroids and directly suppresses the adrenal cortex. A reduction in 17-hydroxycorticosteroids in the absence of decreased corticosteroid concentrations and increased formation of 6-β-hydroxycortisol have been reported.

    12.2 Pharmacodynamics

    The pharmacodynamics of mitotane are unknown.

    12.3 Pharmacokinetics

    Absorption

    Following oral administration of LYSODREN, 40% of the dose is absorbed.

    Distribution

    Mitotane is found in most tissues of the body; however, fat is the primary site of distribution.

    Elimination

    Following discontinuation of mitotane, the plasma terminal half-life ranges from 18 to 159 days (median 53 days).

    Metabolism

    Mitotane is converted to a water-soluble metabolite.

    Excretion

    No unchanged mitotane is found in urine or bile. Approximately 10% of the administered dose is recovered in the urine as a water-soluble metabolite. A variable amount of metabolite (1%-17%) is excreted in the bile.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    The carcinogenicity and mutagenicity of mitotane are unknown.
