Lymphocyte and neutrophil decreases suggest a general decrease in immune responsiveness
“dose-dependent decreases in lymphocytes and neutrophils following repeated lurbinectedin administration suggest that there may have been a general decrease in immune responsiveness.”
Highest tissue levels in spleen, lymph nodes, liver, thyroid, kidney, lung, skin; lowest in brain and testes
“The lowest radioactivity concentrations were detected in the brain (<5 and <2.3 ng-eq/g for male and female rats, respectively) and testes (<12 ng-eq/g). The highest values of total activity were in spleen, followed by lymph nodes, liver, thyroid glands, kidney, lung and skin.”

Modality-specific risk
Embryofetal lethality (no viable fetuses in rat EFD study)
“There were no viable fetuses in lurbinectedin-treated dams. A warning for embryo-fetal toxicity is included in the label”
