WARNINGS AND PRECAUTIONS (5) 01/2024

1 Indications And Usage


LYSODREN is indicated for the treatment of patients with inoperable, functional or nonfunctional, adrenocortical carcinoma (ACC).


LYSODREN is an adrenal cytotoxic agent indicated for the treatment of patients with inoperable, functional or nonfunctional, adrenocortical carcinoma (ACC). (1)

2 Dosage And Administration


  • The recommended initial dose of LYSODREN is 2000 mg to 6000 mg orally, in three or four divided doses per day with food. (2.3)
  • Titrate LYSODREN dose to achieve a plasma level of 14 to 20 mg/L. (2.3)
  • LYSODREN is lipophilic and accumulates in adipose tissue. (2.3)

2.1Recommended Evaluation and Testing Before Initiating LYSODREN


Before initiating LYSODREN, evaluate pelvic ultrasound in premenopausal women, liver functions tests and complete blood count [see Warnings and Precautions (5.3, 5.4, 5.5)].

2.2General Precautions


LYSODREN is a hazardous drug. Advise caregivers to wear disposable gloves when handling LYSODREN tablets [see References (15) and Storage and Handling (16)].

2.3Recommended Dosage and Administration



Recommended Dosage
  • The recommended initial dose of LYSODREN is 2000 mg to 6000 mg orally, in three or four divided doses per day.
  • Monitor mitotane plasma levels and increase the dose based on patient tolerance and clinical response incrementally to achieve a mitotane plasma level of 14 to 20 mg/L, or as tolerated. Consider monitoring mitotane plasma levels every 2 weeks after starting treatment and after each dose adjustment.
  • The target plasma level is usually reached within a period of 3 to 5 months.
  • Monitor mitotane plasma levels periodically (e.g., monthly). Severe neurotoxicity may occur with levels > 20 mg/L.


Dose Adjustments, Monitoring and Discontinuation
  • In case of mitotane plasma levels above 20 mg/L without toxicities, consider reducing the dose by 50 to 75%.
  • Monitor mitotane plasma levels regularly (e.g., every two months) after discontinuation of treatment. Due to the prolonged half-life, significant levels may persist for weeks after cessation of therapy.
  • LYSODREN is lipophilic and accumulates in adipose tissue. Despite maintaining a constant dose, mitotane levels may suddenly increase. Monitor mitotane plasma levels even when LYSODREN has been withheld as adipose tissue may continue to release mitotane [see Clinical Pharmacology (12.3)]. Due to adipose tissue accumulation of mitotane, close monitoring of mitotane plasma levels is recommended in overweight patients and patients with recent weight loss.


Administration
  • Swallow LYSODREN tablets whole; do not crush, chew or split.
  • Take LYSODREN with food. Timing of the dose relative to meals must be consistent. Administration with high fat food enhances absorption [See Clinical Pharmacology Section (12.3)].
  • Do not take tablets showing signs of deterioration.
  • Caregivers should wear disposable gloves when handling the tablets. Avoid exposure to crushed and/or broken tablets. If contact with crushed/broken tablets occurs, wash the contaminated skin immediately and thoroughly.
  • If a patient misses a dose, instruct the patient to take the next dose as scheduled.
  • If a patient vomits after taking a dose, instruct the patient to take the next dose as scheduled.

    • Hematologic Toxicity: Monitor complete blood counts prior to starting LYSODREN, during dose titration and as clinically indicated. Withhold, reduce the dose or permanently discontinue based on severity. (5.5)
    • Prolonged Bleeding Time: Prolonged bleeding time has occurred in patients treated with mitotane and this should be taken into account when surgery is considered. (5.6)
    • Embryo-Fetal Toxicity: Can cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus and to use effective, nonhormonal contraception. (5.8)

    5.1Adrenal Insufficiency and Adrenal Crisis


    Adrenal Insufficiency

    LYSODREN can cause adrenal insufficiency or worsen existing adrenal insufficiency in patients with adrenocortical carcinoma.

    Monitor for both glucocorticoid and mineralocorticoid insufficiency and replace systemic corticosteroids accordingly. Due to increased steroid clearance and increase of steroid-binding protein, high-dose replacement therapy may be required and free cortisol and corticotropin (ACTH) should be monitored to adapt the systemic corticosteroids.

    Withhold, reduce the dose, or permanently discontinue LYSODREN based on severity [see Dosage and Administration (2.4)].


    Adrenal Crisis in the Setting of Shock, Severe Trauma or Infection

    LYSODREN can cause adrenal suppression and adrenal crisis in the setting of shock, severe trauma or infection.

    Advise patients of the signs and symptoms of adrenal suppression and to contact their healthcare provider immediately if shock, trauma, infection, or adrenal suppression occurs. Withhold LYSODREN before planned surgeries.

    Temporarily withhold LYSODREN during shock, trauma, infection or adrenal suppression [see Dosage and Administration (2.4)].

    Provide supportive care and administer systemic corticosteroids until recovery.

    5.2Central Nervous System Toxicity


    LYSODREN can cause central nervous system toxicity, including sedation, lethargy, and vertigo [see Adverse Reactions (6.1)].

    Monitor behavioral and neurologic assessments and mitotane plasma levels at regular intervals. Mitotane plasma levels exceeding 20 mg/L are associated with a greater incidence of toxicity.

    In cases of cognitive dysfunction, thyroid function should be evaluated as mitotane may induce hypothyroidism.

    LYSODREN can impair the ability to drive and operate machinery. Advise patients not to drive or operate hazardous machinery if they are experiencing CNS adverse reactions. Withhold, reduce the dose, or permanently discontinue LYSODREN based on severity [see Dosage and Administration (2.4)].

    5.3Ovarian Macrocysts in Premenopausal Women


    LYSODREN can cause non-malignant, multiple and bilateral ovarian macrocysts in premenopausal women.

    Ovarian macrocysts can be symptomatic (e.g., pelvic pain or discomfort, or menstrual irregularities) or asymptomatic.

    Complications from these cysts, including adnexal torsion and hemorrhagic cyst rupture, have occurred.

    Advise female patients to contact their healthcare provider immediately for gynecological symptoms such as vaginal bleeding and/or pelvic pain [see Adverse Reactions (6.1)].

    Monitor pelvic imaging in premenopausal females at baseline and in regular intervals during treatment with LYSODREN.

    Withhold, reduce the dose, or permanently discontinue LYSODREN based on severity [see Dosage and Administration (2.4)].

    5.4Hepatotoxicity


    LYSODREN can cause hepatoxicity, including liver injury or failure.

    Monitor liver function tests prior to starting treatment with LYSODREN, during dose titration, and periodically during treatment as clinically indicated.

    Isolated gamma-glutamyl transferase (GGT) elevation may occur.

    Withhold, reduce the dose, or permanently discontinue LYSODREN based on severity of hepatoxicity [see Dosage and Administration (2.4)].

    5.5Hematologic toxicity


    LYSODREN can cause leukopenia, anemia and thrombocytopenia [see Adverse Reactions (6)]. Monitor complete blood counts including neutrophil count prior to starting treatment with LYSODREN, during dose titration, and periodically during treatment as clinically indicated. Withhold, reduce the dose, or permanently discontinue LYSODREN based on severity of cytopenia [see Dosage and Administration (2.4)].

    5.6Prolonged Bleeding Time


    LYSODREN can cause platelet function disorders due to abnormal adenosine diphosphate (ADP)-induced platelet aggregation. Some patients may have a prolonged bleeding time, while others may have a normal bleeding time.

    Routine in vitro bleeding time is not suitable to detect this platelet defect and to assess bleeding risk.

    Perform ADP-inducted platelet aggregometry testing prior to surgery or dental procedures to determine mitotane-induced bleeding risk. For patients with prolonged bleeding time, withhold or reduce the dose of LYSODREN as clinically indicated.

    5.7Hormone binding protein


    Mitotane has been shown to increase plasma levels of hormone binding proteins (e.g., sex hormone-binding globulin (SHBG) and corticosteroid-binding globulin (CBG)). This should be taken into account when interpreting the results of hormonal assays and may result in gynecomastia.

    5.8Embryo-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 nonhormonal contraception, during treatment with LYSODREN and after discontinuation of treatment for as long as mitotane plasma levels are detectable, since LYSODREN can render some hormonal contraceptives ineffective [see Drug Interactions (7.2), Use in Specific Populations (8.1, 8.3)].

    7 Drug Interactions


    • Spironolactone: Avoid concomitant use with LYSODREN. (7.1)
    • Certain CYP3A Substrates: Avoid concomitant use with LYSODREN. (7.2)
    • Hormonal contraceptives: Avoid concomitant use with LYSODREN. (7.2)
    • Warfarin: Avoid concomitant use with LYSODREN. (7.2)

    7.1Effects of Other Drugs on LYSODREN


    Spironolactone

    Spironolactone may block the action of mitotane. Avoid concomitant use of mitotane with spironolactone [see Clinical Pharmacology (12.3)].

    7.2Effects of LYSODREN on Other Drugs



    Certain CYP3A substrates

    Mitotane is a strong CYP3A inducer. Concomitant use of LYSODREN may decrease the levels of CYP3A substrates, which may reduce the activity of these substrates [see Clinical Pharmacology (12.3)].

    Avoid concomitant use of LYSODREN with other CYP3A substrates, where minimal level changes may lead to serious therapeutic failures. If concomitant use cannot be avoided, modify the dosage of the CYP3A substrate in accordance with the approved product labeling.


    Hormonal Contraceptives

    Avoid concomitant use of LYSODREN with hormonal contraceptives [see Warnings and Precautions (5.8), Use in Specific Populations (8.3)].


    Warfarin

    Mitotane may induce the metabolism of warfarin, which may reduce its level and its efficacy [see Clinical Pharmacology (12.3)].

    Avoid concomitant use of LYSODREN with warfarin. If concomitant use cannot be avoided, monitor INR more frequently and adjust warfarin dose as recommended in accordance with the recommendations in the warfarin Prescribing Information.

    8 Use In Specific Populations


    • Lactation: Advise not to breastfeed. (8.2)
    • Hepatic Impairment: LYSODREN is not recommended for patients with severe hepatic impairment. In patients with mild to moderate hepatic impairment, monitor mitotane plasma levels frequently and modify the dosage as needed. (8.6)
    • Renal Impairment: LYSODREN is not recommended for patients with severe renal impairment. In patients with mild or moderate renal impairment, monitor mitotane plasma levels frequently and modify the dosage as needed. (8.7)

    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.

    In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

    8.2 Lactation



    Risk Summary

    Mitotane is excreted in human milk; however, the effect of LYSODREN on the breastfed child, or on milk production is unknown. Because of the potential for serious adverse reactions in a breastfed child, advise women not to breastfeed 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



    Pregnancy Testing

    Verify the pregnancy status of females of reproductive potential prior to initiating LYSODREN [see Use in Specific Populations (8.1)].


    Contraception

    LYSODREN can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)].


    Females

    Advise females of reproductive potential to use effective nonhormonal contraception during treatment with LYSODREN and after discontinuation of therapy for as long as mitotane plasma levels are detectable [see Clinical Pharmacology (12.3)]. LYSODREN can render hormonal contraceptives ineffective [see Drug Interaction (7.2)].

    8.4 Pediatric Use


    Effectiveness in pediatric patients has not been established.

    Based on published case reports, mitotane may negatively impact neuro-psychological development (e.g., motor and speech delay, memory impairment) in children and adolescents. In cases of cognitive dysfunction, thyroid function should be evaluated as mitotane may induce hypothyroidism. Other effects of mitotane observed in pediatric patients that are cited in medical literature or in a pharmacovigilance database include growth delay and estrogenic-like effects such as uterine bleeding, breast development in females and gynecomastia in males.

    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 older and younger patients. In general, dose selection for an older 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


    Mitotane is metabolized through the liver and mitotane plasma levels may increase if liver function is impaired.

    Because of the increased risk of adverse reactions in patients with mild or moderate hepatic impairment, monitor mitotane plasma levels more frequently and modify the dosage as needed [see Dosage and Administration (2.3)]. LYSODREN is not recommended for use in patients with severe hepatic impairment [see Warnings and Precautions (5.4)].

    8.7 Renal Impairment


    Mitotane is eliminated through the kidney and mitotane plasma levels may increase if renal function is impaired.

    Because of the increased risk of adverse reactions in patients with mild and moderate renal impairment, monitor mitotane plasma levels more frequently and modify the dosage as needed [see Dosage and Administration (2.4)]. LYSODREN is not recommended for use in patients with severe renal impairment.

    10 Overdosage


    LYSODREN overdosage (plasma levels are above 20 mg/L) can cause central nervous system toxicity, including sedation, lethargy, and vertigo, as well as muscular weakness and gait disturbance. Withhold LYSODREN as clinically indicated for signs or symptoms of toxicity.

    LYSODREN is lipophilic and has a prolonged half-life; therefore, it may take weeks for plasma levels to decrease. LYSODREN is not likely to be dialyzable. Increase the frequency of mitotane plasma level monitoring, as clinically indicated.

    11 Description


    LYSODREN (mitotane) is an oral adrenal cytotoxic agent. The chemical name is (±)-1,1-dichloro-2-(o-chlorophenyl)-2-(p-chlorophenyl) ethane (also known as o,p'-DDD). The chemical structure is:

    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 levels and increased formation of 6-β-hydroxycortisol have been reported.

    12.2 Pharmacodynamics


    Mitotane exposure-response relationships and the time course of pharmacodynamic response have not been fully characterized.

    12.3 Pharmacokinetics



    Absorption

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


    Effect of Food

    The effect of food on the absorption of mitotane (LYSODREN) is not known.


    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. Mitotane metabolism includes hepatic and extrahepatic metabolism. Mitotane is metabolized to 1,1-(o,p'-dichlorodiphenyl) acetic acid (o,p'-DDA), as the major circulating 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.


    Specific Populations


    Patients with Hepatic or Renal Impairment

    The pharmacokinetics of mitotane have not been studied in patients with hepatic impairment or patients with renal impairment.

    This Medication Guide has been approved by the U.S. Food and Drug Administration. Issued: 01/2024
    What is the most important information I should know about LYSODREN?
    LYSODREN can cause serious side effects including:
    Adrenal Insufficiency and Adrenal Crisis.
    • Adrenal Insufficiency. LYSODREN can cause your adrenal glands to stop making enough corticosteroid hormones (adrenal insufficiency) or make this problem worse in people with cancer of the adrenal glands (adrenocortical carcinoma). Your healthcare provider may temporarily stop, reduce your dose, or permanently stop treatment with LYSODREN if you develop adrenal insufficiency during treatment.
    • Adrenal Crisis. LYSODREN can cause your adrenal glands to suddenly stop making enough corticosteroid hormones (adrenal crisis). You are at increased risk for developing adrenal crisis if you experience shock, severe injury, or infection during treatment with LYSODREN. Adrenal crisis may lead to death. Tell your healthcare provider right away if you get an injury, infection, or other illness during treatment with LYSODREN. Your healthcare provider will temporarily stop LYSODREN if shock, severe injury, or infections happen during treatment. Tell your healthcare provider if you have any planned surgery.
    Your healthcare provider will check your levels of corticosteroid hormones during treatment and may give you corticosteroid medicine if you develop adrenal gland problems. Tell your healthcare provider right away if you develop any signs or symptoms of adrenal gland problems, including:
    • severe weakness
    • confusion
    • pain in the lower back and legs
    • stomach (abdominal) pain
    • nausea, vomiting, or diarrhea
    • feeling lightheaded or dizzy
    • passing out
    • feeling very tired
    • decreased appetite
    • weight loss
    • areas of darkened skin
    • craving salt
    • low blood sugar
    • feeling irritable or depressed
    • hair loss
    See " What are the possible side effects of LYSODREN?" for more information about side effects.
    What is LYSODREN?
    LYSODREN is a prescription medicine used to treat people with cancer of the adrenal glands (adrenocortical carcinoma) that is functional (when the adrenal glands make more corticosteroid hormone than normal) or nonfunctional (when the adrenal glands make less corticosteroid hormone than normal) and the cancer cannot be removed by surgery.
    Effectiveness in pediatric patients has not been established.
    Before taking LYSODREN, tell your healthcare provider about all of your medical conditions, including if you:
    • have an injury, infection or illness
    • plan to have surgery. Tell your healthcare providers you are taking LYSODREN. You may need to stop taking LYSODREN before any surgery and dental procedures.
    • have cysts on your ovaries
    • have liver or kidney problems
    • have bleeding problems
    • are pregnant or plan to become pregnant. LYSODREN can harm your unborn baby. Females who can become pregnant:
      • Your healthcare provider will do a pregnancy test before you start treatment with LYSODREN.
      • Use birth control (contraception) that does not contain hormones (nonhormonal) such as condoms or diaphragms and spermicide during treatment with LYSODREN and for as long as your healthcare provider tells you to after you stop treatment. Birth control methods that contain hormones such as birth control pills, injections, or patches may not work as well during and after treatment with LYSODREN. Tell your healthcare provider right away if you become pregnant or think you may be pregnant during treatment with LYSODREN.
    • are breastfeeding or plan to breastfeed. LYSODREN can pass into your breast milk and may harm your baby. Do not breastfeed during treatment and after you stop taking LYSODREN until your healthcare provider tells you it is okay. Talk to your healthcare provider about the best way to feed your baby during and after treatment with LYSODREN.
    Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Taking LYSODREN with certain other medicines may affect the way LYSODREN and the other medicines work and may increase your risk of side effects.
    Especially tell your healthcare provider if you take:
    • spironolactone
    • midazolam or other CYP3A substrates
    • hormonal birth control
    • warfarin
    Ask your healthcare provider about any other medicine that may not be uled above.

    • Ovarian cysts in premenopausal women. LYSODREN can cause noncancerous large cysts (macrocysts) on the ovaries of women who have not gone through menopause (premenopausal). The cysts may cause pain or discomfort in your pelvic area and abnormal periods, or they may not cause any symptoms at all. If you are premenopausal, your healthcare provider will do an ultrasound of your ovaries before starting LYSODREN and as needed during treatment. Tell your healthcare provider right away if you develop vaginal bleeding or pelvic pain.
    • Liver problems. LYSODREN can cause liver problems, including liver injury or liver failure. Tell your healthcare provider right away if you develop any signs and symptoms of liver problems during LYSODREN treatment, including:

    • itching
    • loss of appetite
    • nausea, vomiting or diarrhea
    • bleeding or bruising

    • fever
    • trouble breathing
    • unusual bruising or bleeding
    • dizziness or lightheadedness

    • Prolonged bleeding time. LYSODREN can cause bleeding that lasts longer than usual. If you need to have surgery or dental procedures during treatment with LYSODREN, your healthcare provider will do blood tests to check for prolonged bleeding risks. Tell your healthcare provider right away if you develop signs or symptoms of prolonged bleeding during treatment with LYSODREN, including:
    • unusual bleeding or bleeding that will not stop
    • bruising
    • lightheadedness
    • vomiting blood or your vomit looks like coffee grinds
    • blood in your stool or black stool that looks like tar
    • pink or brown urine
    • coughing up blood or blood clots
    • menstrual bleeding that is heavier than normal
    • nose bleeds that happen often
    • Changes in hormone levels. LYSODREN may cause changes in certain hormone levels in your blood. If you are male, your breasts may swell or become larger during treatment.
    Your healthcare provider will do blood tests before you start treatment with LYSODREN, during your treatment, and after you stop treatment with LYSODREN to check mitotane levels in your body and to check for side effects.
    Your healthcare provider may change your dose, temporarily stop, or permanently stop treatment with LYSODREN if you develop certain side effects.
