Study Summary

This research study involves the study drug lurbinectedin in combination with doxorubicin. This research has two parts. The first part is being done to determine the tolerability of lurbinectedin with doxorubicin in people with soft tissue sarcoma. The second part is a randomized study to determine which is more effective at treating leiomyosarcoma, lurbinectedin with doxorubicin or lurbinectedin alone.

Primary Outcome

The MTD will be defined as the dose where less than 1 in 3 patients experience a DLT. At least 6 patients must be treated at this dose level. DLTs will be defined as toxicities experienced by participants enrolled to the phase 1b portion of the trial that are considered at least possibly related to the treatment regimen, occur during the first cycle of treatment.
