Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a multicenter, prospective phase Ib trial based on a dose escalation study design (3+3 traditional design) assessing three dose levels of Trabectedin given with durvalumab, followed by two expansion cohorts once the MTD is established.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Combination of trabectedin with durvalumab

Trabectedin will be administered intraveinously, on day 1 of each cycle, every three weeks, as appropriate for assigned dose level.

Durvalumab will be administered intraveinously, at fixed doses of 1120 mg (equivalent to 15 mg/kg), on day 2 of each cycle, every three weeks.

Group Type EXPERIMENTAL

Combination of trabectedin with durvalumab

Intervention Type DRUG

Dose Escalation : 3 doses of trabectedin given in combination with durvalumab (fixed dose) will be investigated.

A treatment cycle consists of 3 weeks. Treatment may continue until disease progression or study discontinuation (withdrawal of consent, intercurrent illness, unacceptable adverse event or any other changes unacceptable for further treatment, etc.).

Expansion cohorts: Once the Maximum Tolerated Dose (MTD) has been defined, the expansion cohorts will be opened. All patients will be treated at the MTD of Trabectedin (as defined in the dose escalation part of the trial) given in association with Durvalumab with the same schedule as in the dose escalation part of the trial.
