Trial Design

2Treatment groups
Experimental Treatment
Group I: Group 2 - Dose ExpansionExperimental Treatment2 Interventions
It is anticipated that Group 2 patients will receive tomivosertib at a dose of 100 mg orally twice daily (BID) during the 'run-in' period, which is taken in combination with weekly paclitaxel (according to market label) during the 'post run-in' period.
Group II: Group 1 - Dose FindingExperimental Treatment2 Interventions
The first 3 patients enrolled in Group 1 will receive tomivosertib at a dose of 100 mg orally twice daily (BID), under fasting conditions, and will be assessed for dose limiting toxicities (DLTs) during this 'run-in' period. They will also receive the first cycle of tomivosertib IN COMBINATION with weekly paclitaxel in the 'post run-in' period. Depending on the occurrence/absence of DLTs, this first group of 3 patients may need to be expanded (up to 9 patients) or the trial may proceed to start enrollment in Group 2 (detailed in the arm below).
