Brief summary
This is a phase 2 study conducted in two sequential stages: The first stage is an Italian single institution, single arm, pilot study, aimed at exploring the activity of the combination T and P in myxoid liposarcoma patients who achieved a stable disease after a minimum of 4 cycles of T alone. If a minimum required activity will be demonstrated from the first stage, the second stage of the study will be conducted;otherwise, the study will be stopped. The second stage is an Italian open-label, multicenter, randomized, double arm, phase II trial, aimed at evaluating the combination of T and P in myxoid liposarcoma and G1 or G2 dedifferentiated liposarcomas compared to the standard treatment with T alone. Patients will be randomized with a 1:1 ratio to treatments arms as specified below: * Control arm (A): T alone * Experimental arm (B): T in combination with P
Detailed description
In the specific the first stage will be an Italian mono-institutional, single arm, pilot study exploring the activity of the combination of T and P in myxoid liposarcoma patients who achieved a stable disease after a minimum of 4 cycles of T alone. If a minimum required activity will be demonstrated from the first stage, the second stage of the study will be conducted; otherwise, the study will be stopped. The second stage will be an Italian multicenter, open-label, randomized, double arm, phase II trial, aimed at evaluating the combination of T and P in myxoid liposarcoma and G1 or G2 dedifferentiated liposarcomas compared to the standard treatment. Patients will be randomized by a centralized computer system with a 1:1 ratio to one of the following two arms: * Control arm (A): T alone * Experimental arm (B): T in combination with P The pilot study will be conducted in Italy at Istituto Nazionale Tumori Milano in order to recruit 10 evaluable patients. The second stage will be conducted in approximately 10 italian centers in order to recruit 80 evaluable patients.
Interventions
DRUGTrabectedin
Patients will be treated with Trabectedin administered at a dose of 1.5 mg/m2-1.3 mg/m2 (according to investigator's choice, with a top-dose of 2.6 total mg per cycle) as a 24-hour continuous infusion via a central venous access every 3 weeks and pioglitazone given continuously at the daily dose of 45 mg by oral route.
DRUGPioglitazone Oral Product
Patients will be treated with Trabectedin administered at a dose of 1.5 mg/m2-1.3 mg/m2 (according to investigator's choice, with a top-dose of 2.6 total mg per cycle) as a 24-hour continuous infusion via a central venous access every 3 weeks and pioglitazone given continuously at the daily dose of 45 mg by oral route.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Objective response (OR) in patients with myxoid liposarcomas according to RECIST criteria or CHOI criteria | From the date of the enrollment up to 24 months | The primary activity endpoint is the number of responders. Patients will be considered as responders if they reach a CR or PR as best response during treatment according to RECIST criteria or according to Choi criteria. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number and severity of Adverse Events | up to 24 months | The safety profile of T+P is assessed by the frequency and type of treatment emergent adverse events, graded according to NCI-CTCAE v5.0, frequency and nature of SAEs. |
| Maximum Plasma Concentration [Cmax] | up to 24 months | The analysis of \[Cmax\] will be performed on the first four enrolled patients within the safety analysis set 1. |
