bPatients with isolated Grade 4 neutropenia (neutrophil count <500 cells/mm3) may receive granulocyte colony-stimulating factor (G-CSF) prophylaxis rather than undergo lurbinectedin dose reduction.

  • For neutrophil count <500 cells/mm3 or any value less than lower limit of normal, the use of G-CSF
    is recommended1


Preparation, ADMINISTRATION, AND STORAGE of ZEPZELCATM (lurbinectedin)

ZEPZELCA is a hazardous drug. Follow applicable special handling and disposal procedures.1

Preparation and Administration1

Sterile Water in ZEPZELCA Vial Icon
  • Inject 8 mL of Sterile Water for Injection USP into the vial, yielding a solution containing
    0.5 mg/mL of ZEPZELCA. Shake the vial until complete dissolution
ZEPZELCA Solution Inspection Magnifying Glass Icon
  • 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
Required ZEPZELCA Volume Calculator Icon
  • Calculate the required volume of reconstituted solution as follows:
    Volume (mL) =
    Body Surface Area (m2) x Individual Dose (mg/m2)
    0.5 mg/mL
ZEPZELCA Administration Central Venous Line Icon
  • 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)
ZEPZELCA Administration Peripheral Venous Line Icon
  • 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)
ZEPZELCA Solution Inspection Magnifying Glass Icon
  • 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 Solution1

Proper ZEPZELCA Storing Temperature Thermometer Icon
  • 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 refrigerated (2 °C–8 °C;
    36 °F–46 °F) conditions

INDICATION

ZEPZELCA™ (lurbinectedin) is indicated for the treatment of adult patients with metastatic small cell lung cancer (SCLC) with disease progression on or after platinum-based chemotherapy.

This indication is approved under accelerated approval based on overall response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).

IMPORTANT SAFETY INFORMATION

Myelosuppression
ZEPZELCA can cause myelosuppression. In clinical studies of 554 patients with advanced solid tumors receiving ZEPZELCA, 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.

Hepatotoxicity
ZEPZELCA can cause hepatotoxicity. In clinical studies of 554 patients with advanced solid tumors receiving ZEPZELCA, 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.

Embryo-Fetal Toxicity
ZEPZELCA can cause fetal harm when administered to a pregnant woman. 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.

Lactation
There are no data on the presence of ZEPZELCA in human milk, however, 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.

MOST COMMON ADVERSE REACTIONS

The most common adverse reactions, including laboratory abnormalities, (≥20%) are leukopenia (79%), lymphopenia (79%), fatigue (77%), anemia (74%), neutropenia (71%), increased creatinine (69%), increased alanine aminotransferase (66%), increased glucose (52%), thrombocytopenia (37%), nausea (37%), decreased appetite (33%), musculoskeletal pain (33%), decreased albumin (32%), constipation (31%), dyspnea (31%), decreased sodium (31%), increased aspartate aminotransferase (26%), vomiting (22%), decreased magnesium (22%), cough (20%), and diarrhea (20%).

DRUG INTERACTIONS

Strong and Moderate CYP3A Inhibitors

Avoid coadministration with a strong or a moderate CYP3A inhibitor as this increases lurbinectedin systemic exposure which may increase the incidence and severity of adverse reactions to ZEPZELCA. If coadministration of ZEPZELCA with a moderate CYP3A inhibitor cannot be avoided, consider dose reduction of ZEPZELCA, if clinically indicated.

Strong and Moderate CYP3A Inducers

Avoid coadministration with a strong or moderate CYP3A inducer. Coadministration with a strong CYP3A inducer decreases lurbinectedin systemic exposure which may reduce ZEPZELCA efficacy.

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%).
