                  Contraindications

                  None

                  Cautions

                  May cause myelosuppression; monitor blood cell counts, including neutrophil count and platelet count, before each administration

                  Hepatotoxicity reported; monitor liver function tests before initiating therapy, periodically during treatment, and as clinically indicated

                  Based on animal data and mechanism of action, fetal harm may occur when administered to pregnant females

                  Drug interaction overview

                  • Lurbinectedin is a CYP3A4 substrated
                  • Strong or moderate CYP3A4 inhibitors
                    • Avoid coadministration
                    • Coadministration with a strong or moderate CYP3A inhibitor increases systemic exposure and risk of adverse reactions to lurbinectedin
                  • Strong or moderate CYP3A4 inducers
                    • Avoid coadministration
                    • Coadministration with a strong CYP3A4 inducer decreases systemic exposure to and efficacy of lurbinectedin

                  Pregnancy & Lactation

                  Pregnancy

                  Based on animal data and mechanism of action, fetal harm may occur when administered to pregnant females

                  No data are available regarding risk in pregnant females

                  Advise pregnant females of potential risk to a fetus

                  Verify pregnancy status of females of reproductive potential before initiating treatment

                  Contraception

                  • Females of reproductive potential: Use effective contraception during treatment and for 6 months after final dose
                  • Males with a female sexual partner of reproductive potential: Use effective contraception during treatment and for 4 months after final dose

                  Animal data

                  • IV administration of a single lurbinectedin dose (~0.2x the 3.2 mg/m2 clinical dose) to pregnant rats during organogenesis caused embryolethality

                  Lactation

                  There are no data on presence of in human milk, effects on breastfed children, or on milk production

                  Advise lactating females not to breastfeed during treatment and for 2 weeks after final dose

                  Pregnancy Categories

                  A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

                  B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

                  C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

                  D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

                  X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

                  NA: Information not available.

                  Pharmacology

                  Mechanism of Action

                  An alkylating drug; it 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

                  Absorption

                  Peak plasma concentration: 107 mcg/mL

                  AUC: 551 mcg⋅hr/L

                  Distribution

                  Vd (steady-state): 504 L

                  Protein bound: ~99%

                  Metabolism

                  Primarily metabolized by CYP3A4

                  Elimination

                  Half-life: 51 hr

                  Clearance: 11 L/hr

                  Excretion: Feces (89%; <0.2% unchanged), urine (6%; 1% unchanged)
