                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

                Extravasation

                • Extravasation resulting in skin and soft tissue injury, including necrosis requiring debridement, can occur
                • Consider using a central venous catheter to reduce extravasation risk, particularly in patients with limited venous access; monitor for signs and symptoms of extravasation during infusion
                • If extravasation occurs, immediately discontinue infusion, remove infusion catheter, and monitor for signs and symptoms of tissue necrosis; the time to onset of necrosis after extravasation may vary
                • Administer supportive care and consult with appropriate medical specialist as needed for signs and symptoms of extravasation; administer subsequent infusions at site that was not affected by extravasation

                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.

                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
