    2.4 Preparation, Administration and Storage

    ZEPZELCA is a hazardous drug. Follow applicable special handling and disposal procedures1.

    Preparation and Administration

    Inject 8 mL of Sterile Water for Injection USP into the vial, yielding a solution containing 0.5 mg/mL lurbinectedin. Shake the vial until complete dissolution.
    Visually inspect the solution for particulate matter and discoloration. The reconstituted solution is a clear, colorless or slightly yellowish solution, essentially free of visible particles.
    Calculate the required volume of reconstituted solution as follows:
     
    volume calculation
    For administration through a central venous line, withdraw the appropriate amount of reconstituted solution from the vial and add to an infusion container containing at least 100 mL of diluent (0.9% Sodium Chloride Injection USP or 5% Dextrose Injection USP).
    For administration through a peripheral venous line, withdraw the appropriate amount of reconstituted solution from the vial and add to an infusion container containing at least 250 mL of diluent (0.9% Sodium Chloride Injection USP or 5% Dextrose Injection USP).
    Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. If particulate matter is observed, do not administer.

    Storage of Infusion Solution

    If not used immediately after reconstitution or dilution, the ZEPZELCA solution can be stored prior to administration for up to 24 hours following reconstitution, including infusion time, at either room temperature/ ambient light or under refrigeration at 2ºC-8ºC (36ºF-46ºF) conditions.
  • 3 DOSAGE FORMS AND STRENGTHS

    For injection: 4 mg of lurbinectedin as a sterile, preservative-free, white to off-white lyophilized powder in a single-dose vial for reconstitution prior to intravenous infusion.

  • 4 CONTRAINDICATIONS

    None.

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Myelosuppression

    ZEPZELCA can cause myelosuppression.

    In clinical studies of 554 patients with advanced solid tumors receiving ZEPZELCA [see Adverse Reactions (6.1)], Grade 3 or 4 neutropenia occurred in 41% of patients, with a median time to onset of 15 days and a median duration of 7 days. Febrile neutropenia occurred in 7% of patients. Sepsis occurred in 2% of patients and was fatal in 1% (all cases occurred in patients with solid tumors other than SCLC). Grade 3 or 4 thrombocytopenia occurred in 10%, with a median time to onset of 10 days and a median duration of 7 days. Grade 3 or 4 anemia occurred in 17% of patients.

    Administer ZEPZELCA only to patients with baseline neutrophil count of at least 1,500 cells/mm3 and platelet count of at least 100,000/mm3. Monitor blood counts including neutrophil count and platelet count prior to each administration. For neutrophil count less than 500 cells/mm3 or any value less than lower limit of normal, the use of G-CSF is recommended. Withhold, reduce the dose, or permanently discontinue ZEPZELCA based on severity [see Dosage and Administration (2.2)].

    5.2 Hepatotoxicity

    ZEPZELCA can cause hepatotoxicity.

    In clinical studies of 554 patients with advanced solid tumors receiving ZEPZELCA [see Adverse Reactions (6.1)], Grade 3 elevations of ALT and AST were observed in 6% and 3% of patients, respectively, and Grade 4 elevations of ALT and AST were observed in 0.4% and 0.5% of patients, respectively. The median time to onset of Grade ≥3 elevation in transaminases was 8 days (range: 3 to 49), with a median duration of 7 days.

    Monitor liver function tests, prior to initiating ZEPZELCA, periodically during treatment, and as clinically indicated. Withhold, reduce the dose, or permanently discontinue ZEPZELCA based on severity [see Dosage and Administration (2.2)].

    5.3 Embryo-Fetal Toxicity

    Based on animal data and its mechanism of action ZEPZELCA can cause fetal harm when administered to a pregnant woman. Intravenous administration of a single dose of lurbinectedin (approximately 0.2 times the 3.2 mg/m2 clinical dose) to pregnant animals during the period of organogenesis caused 100% embryolethality in rats. Advise pregnant women of the potential risk to a fetus. Advise female patients of reproductive potential to use effective contraception during treatment with ZEPZELCA and for 6 months after the final dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with ZEPZELCA and for 4 months after the final dose [see Use in Specific Populations (8.1, 8.3)].

  • 6 ADVERSE REACTIONS

    The following clinically significant adverse reactions are described elsewhere in the labeling:

    Myelosuppression [see Warnings and Precautions (5.1)]
    Hepatotoxicity [see Warnings and Precautions (5.2)]

    6.1 Clinical Trials 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.

    The pooled safety population described in the WARNINGS AND PRECAUTIONS reflect exposure to ZEPZELCA as a single agent at a dose of 3.2 mg/m2 intravenously every 21 days in 554 patients with advanced solid tumors. Among 554 patients who received ZEPZELCA, including 105 patients with small cell lung cancer (SCLC) in PM1183-B-005-14 (Study B-005), 24% were exposed for 6 months or longer and 5% were exposed for greater than one year.

    Small Cell Lung Cancer (SCLC)

    The safety of ZEPZELCA was evaluated in a cohort of 105 patients with previously treated SCLC in Study B-005 [see Clinical Studies (14)]. Patients received ZEPZELCA 3.2 mg/m2 intravenously every 21 days. All patients in this study received a pre-specified anti-emetic regimen consisting of a corticosteroid and serotonin antagonist. Patients could receive G-CSF for secondary prophylaxis (i.e., after patients had an initial decrease in WBC), but not primary prophylaxis. Among patients who received ZEPZELCA, 29% were exposed for 6 months or longer and 6% were exposed for greater than one year.

    Serious adverse reactions occurred in 34% of patients who received ZEPZELCA. Serious adverse reactions in ≥ 3% of patients included pneumonia, febrile neutropenia, neutropenia, respiratory tract infection, anemia, dyspnea, and thrombocytopenia.

    Permanent discontinuation due to an adverse reaction occurred in two patients (1.9%) who received ZEPZELCA. Adverse reactions resulting in permanent discontinuation in ≥ 1% of patients who received ZEPZELCA, which included peripheral neuropathy and myelosuppression.

    Dosage interruptions due to an adverse reaction occurred in 30.5% of patients who received ZEPZELCA. Adverse reactions requiring dosage interruption in ≥ 3% of patients who received ZEPZELCA included neutropenia, and thrombocytopenia.

    Dose reductions due to an adverse reaction occurred in 25% of patients who received ZEPZELCA. Adverse reactions requiring dosage reductions in ≥ 3% of patients who received ZEPZELCA included neutropenia, febrile neutropenia and fatigue.

    The most common adverse reactions, including laboratory abnormalities, (≥ 20%) were leukopenia, lymphopenia, fatigue, anemia, neutropenia, increased creatinine, increased alanine aminotransferase, increased glucose, thrombocytopenia, nausea, decreased appetite, musculoskeletal pain, decreased albumin, constipation, dyspnea, decreased sodium, increased aspartate aminotransferase, vomiting, cough, decreased magnesium and diarrhea.

  • 7 DRUG INTERACTIONS

    7.1 Effect of Other Drugs on ZEPZELCA

    Strong and Moderate CYP3A Inhibitors

    Coadministration with a strong or a moderate CYP3A inhibitor increases lurbinectedin systemic exposure [see Clinical Pharmacology (12.3)] which may increase the incidence and severity of adverse reactions to ZEPZELCA. Avoid coadministration of ZEPZELCA with strong or moderate CYP3A inhibitors. If the coadministration of ZEPZELCA with a moderate CYP3A inhibitor cannot be avoided, consider dose reduction of ZEPZELCA, if clinically indicated [see Dosage and Administration (2.2)].

    Strong and Moderate CYP3A Inducers

    Coadministration with a strong CYP3A inducer decreases lurbinectedin systemic exposure [see Clinical Pharmacology (12.3)] which may reduce ZEPZELCA efficacy. Avoid coadministration of ZEPZELCA with strong or moderate CYP3A inducers.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary

    Based on animal data and its mechanism of action [see Clinical Pharmacology (12.1)], ZEPZELCA can cause fetal harm when administered to a pregnant woman. There are no available data to inform the risk of ZEPZELCA use in pregnant women. Intravenous administration of a single lurbinectedin dose (approximately 0.2 times the 3.2 mg/m2 clinical dose) to pregnant rats during the period of organogenesis caused embryolethality (see Data).

    Advise pregnant women of the potential risk to a fetus.

    The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. 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.

    Data

    Animal Data

    In a reproductive toxicity study, administration of a single lurbinectedin dose of 0.6 mg/m2 (approximately 0.2 times of the human dose of 3.2 mg/m2) to pregnant rats on Gestation Day 10 resulted in 100% post-implantation loss.

    8.2 Lactation

    Risk Summary

    There are no data on the presence of lurbinectedin in human milk or its effects on the breastfed child or on milk production. Because of the potential for serious adverse reactions from ZEPZELCA in breastfed children, advise women not to breastfeed during treatment with ZEPZELCA and for 2 weeks after the final dose.

    8.3 Females and Males of Reproductive Potential

    ZEPZELCA can cause embryolethality at doses lower than the human dose of 3.2 mg/m2[see Use in Specific Populations (8.1)].

    Pregnancy Testing

    Verify the pregnancy status of females of reproductive potential prior to initiating ZEPZELCA.

    Contraception

    Females

    Advise female patients of reproductive potential to use effective contraception during treatment with ZEPZELCA and for 6 months after the final dose.

    Males

    Advise males with a female sexual partner of reproductive potential to use effective contraception during treatment with ZEPZELCA and for 4 months after the final dose.

    8.4 Pediatric Use

    The safety and effectiveness of ZEPZELCA in pediatric patients have not been established.

    8.5 Geriatric Use

    Of the 105 patients with SCLC administered ZEPZELCA in clinical studies, 37 (35%) patients were 65 years of age and older, while 9 (9%) patients were 75 years of age and older. No overall difference in effectiveness was observed between patients aged 65 and older and younger patients.

    There was a higher incidence of serious adverse reactions in patients ≥ 65 years of age than in patients < 65 years of age (49% vs. 26%, respectively). The serious adverse reactions most frequently reported in patients ≥ 65 years of age were related to myelosuppression and consisted of febrile neutropenia (11%), neutropenia (11%), thrombocytopenia (8%), and anemia (8%) [see Adverse Reactions (6.1)].

    8.6 Hepatic Impairment

    The effect of moderate or severe hepatic impairment (total bilirubin > 1.5 × ULN and any AST) on the pharmacokinetics of lurbinectedin has not been studied. No dose adjustment of ZEPZELCA is recommended for patients with mild hepatic impairment (total bilirubin ≤ ULN and AST > ULN, or total bilirubin 1.0‑1.5 × ULN and any AST) [see Clinical Pharmacology (12.3)].

  • 11 DESCRIPTION

    ZEPZELCA is an alkylating drug. The chemical name of ZEPZELCA (lurbinectedin) is (1’R,6R,6aR,7R,13S,14S,16R)-8,14-dihydroxy-6’,9-dimethoxy-4,10,23-trimethyl-19-oxo-2’,3’,4’,6,7,9’,12,13,14,16-decahydro-6aH-spiro[7,13-azano-6,16-(epithiopropanooxymethano) [1,3]dioxolo[7,8]isoquinolino[3,2-b][3]benzazocine-20,1’-pyrido[3,4-b]indol]-5-yl acetate.

    The molecular formula is C41H44N4O10S. The molecular weight is 784.87g/mol, and the chemical structure is:

    W:\SPL\Lurbinectedin SPL\20200601 - Initial SPL\source\chemical-structure.jpg

    ZEPZELCA for injection 4 mg is supplied as a lyophilized powder in a single-dose vial for reconstitution for intravenous use. The ZEPZELCA lyophilized formulation is comprised of 4 mg lurbinectedin, sucrose (800 mg), lactic acid (22.1 mg), and sodium hydroxide (5.1 mg). Before use, the lyophilizate is reconstituted by addition of 8 mL Sterile Water for Injection USP, yielding a solution containing 0.5 mg/mL lurbinectedin (the calculated concentration is 0.47 mg/mL based on the final volume of 8.5 mL).

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Lurbinectedin is an alkylating drug that binds guanine residues in the minor groove of DNA, forming adducts and resulting in a bending of the DNA helix towards the major groove. Adduct formation triggers a cascade of events that can affect the subsequent activity of DNA binding proteins, including some transcription factors, and DNA repair pathways, resulting in perturbation of the cell cycle and eventual cell death.

    Lurbinectedin inhibited human monocyte activity in vitro and reduced macrophage infiltration in implanted tumors in mice.

    12.2 Pharmacodynamics

    Lurbinectedin exposure-response relationships and the pharmacodynamic time-course for efficacy have not been fully characterized.

    Increased incidence of Grade 4 neutropenia and Grade ≥ 3 thrombocytopenia were observed with increased lurbinectedin exposure.

    Cardiac Electrophysiology

    No large mean increase in QTc (i.e. > 20 ms) was detected following treatment with ZEPZELCA at the recommended dose of 3.2 mg/m2.

    12.3 Pharmacokinetics

    Following the approved recommended dosage, geometric means (%CV) of plasma Cmax and AUC0-inf, were 107 µg/L (79%) and 551 µg•h/L (94%), respectively. No accumulation of lurbinectedin in plasma is observed upon repeated administrations every 3 weeks.

    Distribution

    The volume of distribution of lurbinectedin at steady state is 504 L (39%). Plasma protein binding is approximately 99%, to both albumin and α-1-acid glycoprotein.

    Elimination

    The terminal half-life of lurbinectedin is 51 hours. Total plasma clearance of lurbinectedin is 11 L/h (50%).

    Metabolism

    Lurbinectedin is metabolized by CYP3A4, in vitro.

    Excretion

    After a single dose of radiolabeled lurbinectedin administration, 89% of the radioactivity was recovered in feces (< 0.2% unchanged) and 6% in urine (1% unchanged).

    Specific Populations

    No clinically significant differences in the pharmacokinetics of lurbinectedin were identified based on age (18-85 years), sex, body weight (39-154 kg), mild to moderate renal impairment (CLcr 30 to 89 mL/min) or mild hepatic impairment (total bilirubin ≤ ULN and AST > ULN, or total bilirubin between 1.0 – 1.5 × ULN and any AST). The effects of severe renal impairment (CLcr < 30 mL/min) and moderate or severe hepatic impairment (total bilirubin > 1.5 × ULN and any AST) on the pharmacokinetics of lurbinectedin have not been studied.

    Drug Interactions Studies

    Dedicated clinical drug-drug interaction studies with CYP3A modulators have not been conducted with lurbinectedin.

    In vitro Studies

    Cytochrome P450 (CYP) Enzymes: Lurbinectedin is metabolized by CYP3A4. Lurbinectedin is not an inhibitor of CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP2E1, or CYP3A4. Lurbinectedin is not an inducer of CYP1A2 or CYP3A4.

    Transporter Systems: Lurbinectedin is a substrate of MDR1, but is not a substrate of OATB1P1, OATP1B3, OCT1, or MATE1. Lurbinectedin inhibits MDR1, OATP1B1, OATP1B3, and OCT1 but not BCRP, BSEP, MATE1, OAT1, OAT3, or OCT2.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    Carcinogenicity testing of lurbinectedin has not been performed. Lurbinectedin is genotoxic to mammalian cells in the presence and absence of metabolic activation. Lurbinectedin was not mutagenic in vitro in a bacterial reverse mutation (Ames) assay.

    Fertility studies with lurbinectedin were not performed. There were no findings in reproductive organs in general toxicology studies in rats, dogs, or monkeys; however, the highest doses and exposures in these studies were all at levels lower than those at the human dose of 3.2 mg/m2.

  • 14 CLINICAL STUDIES

    PM1183-B-005-14 (Study B-005; NCT02454972) is a multicenter, open-label, multi-cohort trial evaluating ZEPZELCA as a single agent in patients with advanced or metastatic solid tumors. A cohort of patients with small cell lung cancer (SCLC) with disease progression on or after platinum-based chemotherapy received ZEPZELCA 3.2 mg/m2 by intravenous infusion every 21 days (one cycle). Patients received a median of 4 cycles of ZEPZELCA (range 1 to 24 cycles). The trial excluded patients with central nervous system (CNS) involvement, grade ≥3 dyspnea, daily intermittent oxygen requirement, hepatitis or cirrhosis, and immunocompromised patients. Tumor assessments were conducted every 6 weeks for the first 18 weeks and every 9 weeks thereafter. The major efficacy outcome measure was confirmed investigator-assessed overall response rate (ORR). Additional efficacy outcome measures included duration of response (DoR), and an Independent Review Committee (IRC) assessed ORR using Response Evaluation Criteria in Solid Tumors (RECIST v1.1).

    A total of 105 patients with SCLC who progressed on or after platinum-based chemotherapy were enrolled. The median age was 60 years (range: 40 to 83) with 65% of patients < 65 years and 35% of patients ≥ 65 years, and 60% were male. The majority (75%) of the patients were White, 1% were Asian, 1% were Black and 23% were not reported. Baseline ECOG performance status was 0 or 1 in 92% of patients, and 92% were former/current smokers. All patients received at least one line of platinum-based chemotherapy (range 1-2 lines), and prior radiotherapy had been administered to 71% of patients. Eight patients (8%) had prior immunotherapy in addition to platinum-based chemotherapy. Sixty patients (57%) had platinum-sensitive SCLC, defined as recurrence or progression ≥ 90 days after the last dose of platinum-containing therapy (chemotherapy free interval [CTFI] ≥ 90 days). The remaining 45 patients had platinum-resistant SCLC, defined as recurrence or progression < 90 days after the last dose of platinum-containing therapy (CTFI < 90 days).

    Table 5 summarizes investigator-assessed and independent review committee assessed key efficacy measures in all patients and in platinum-resistant and platinum-sensitive subgroups.

    (lurbinectedin)

    for injection

    What is ZEPZELCA?

    ZEPZELCA is used to treat adults with a kind of lung cancer called small cell lung cancer (SCLC). ZEPZELCA may be used when your lung cancer:
    o
    has spread to other parts of the body (metastatic), and
    o
    you have received treatment with chemotherapy that contains platinum, and it did not work or is no longer working.

    It is not known if ZEPZELCA is safe and effective in children.

    Before receiving ZEPZELCA, tell your healthcare provider about all of your medication conditions, including if you:

    have liver or kidney problems.
    are pregnant or plan to become pregnant. ZEPZELCA can harm your unborn baby.
     
    Females who are able to become pregnant:
    o
    Your healthcare provider should do a pregnancy test before you start treatment with ZEPZELCA.
    o
    You should use effective birth control (contraception) during treatment with and for 6 months after your final dose of ZEPZELCA.
    o
    Tell your healthcare provider right away if you become pregnant or think that you are pregnant during treatment with ZEPZELCA.
     
    Males with female partners who are able to become pregnant should use effective birth control during treatment with and for 4 months after your final dose of ZEPZELCA.
    are breastfeeding or plan to breastfeed. It is not known if ZEPZELCA passes into your breastmilk. Do not breastfeed during treatment with ZEPZELCA and for 2 weeks after your final dose of ZEPZELCA. Talk to your healthcare provider about the best way to feed your baby during treatment with ZEPZELCA.

    Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Certain other medicines may affect how ZEPZELCA works. Know the medicines you take. Keep a list of them to show your healthcare provider and pharmacist when you get a new medicine.

    How will I receive ZEPZELCA?

    ZEPZELCA is given by an intravenous (IV) infusion into a vein over 60 minutes.
    ZEPZELCA is usually given every 21 days.
    Before each treatment with ZEPZELCA, you may receive medicines to help prevent nausea and vomiting or make it less severe.
    Your healthcare provider will decide how long you will continue treatment with ZEPZELCA.
    Your healthcare provider may do certain tests during your treatment with ZEPZELCA to check you for side effects, and to see how well you respond to the treatment.

    What should I avoid while using ZEPZELCA?

    Avoid eating or drinking grapefruit, or products that contain grapefruit juice during treatment with ZEPZELCA.

    What are the possible side effects of ZEPZELCA?

    ZEPZELCA can cause serious side effects, including:
    Low blood cell counts. Low blood counts including low neutrophil counts (neutropenia) and low platelet counts (thrombocytopenia) are common with ZEPZELCA, and can also be severe. Some people with low white blood cell counts may get fever, or an infection throughout the body (sepsis), that can cause death. Your healthcare provider should do blood tests before you receive each treatment with ZEPZELCA to check your blood cell counts.
     
    Tell your healthcare provider right away if you develop:
    o
    fever or any other signs of infection
    o
    unusual bruising or bleeding
    o
    tiredness
    o
    pale colored skin
    Liver problems. Increased liver function tests are common with ZEPZELCA, and can also be severe. Your healthcare provider should do blood tests to check your liver function before you start and during treatment with ZEPZELCA.
     
    Tell your healthcare provider right away if you develop symptoms of liver problems including:
    o
    loss of appetite
    o
    nausea or vomiting
    o
    pain on the right side of your stomach-area (abdomen)
     
    Your healthcare provider may temporarily stop treatment, lower your dose, or permanently stop ZEPZELCA if you develop low blood cell counts or liver problems during treatment with ZEPZELCA.

    The most common side effects of ZEPZELCA include:

    tiredness
    low white and red blood cell counts
    increased kidney function blood test (creatinine)
    increased liver function blood tests
    increased blood sugar (glucose)
    nausea
    decreased appetite
    muscle and joint (musculoskeletal) pain
    low level of albumin in the blood
    constipation
    trouble breathing
    low levels of sodium and magnesium in the blood
    vomiting
    cough
    diarrhea

    These are not all of the possible side effects of ZEPZELCA. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1‑800‑FDA‑1088.
