Lurbinectedin is a novel compound structurally related to trabectedin and with similar mode of action. Pre-clinical data showed a better safety profile than trabectedin. Lurbinectedin has been already tested in different Phase I-II trials showing promising activity in ovarian, pancreatic, breast, small and non-small cell lung cancer as well as in other tumor types, with objective responses averaging 30%, disease stabilization up to 75% and having manageable toxicity. Although lurbinectedin has not been widely tested in mesotheliomas, some mesothelioma patients have been already treated with lurbinectedin where again promising activity has been observed.
