Clinical Trial 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

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Objective response (OR) in patients with myxoid liposarcomas according to RECIST criteria or CHOI criteria	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.	From the date of the enrollment up to 24 months
Secondary	Number and severity of Adverse Events	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.	up to 24 months
Secondary	Maximum Plasma Concentration [Cmax]	The analysis of [Cmax] will be performed on the first four enrolled patients within the safety analysis set 1.	up to 24 months
