What was measured

12-week PFS was defined as the percent probability estimate at 12 weeks based on the Kaplan-Meier method. PFS is defined as the duration of time from study entry to documented disease progression (PD) requiring removal from the study or death. Participants alive without PD were censored at the earliest of the date of the last disease evaluation or start of new anticancer therapy. Per RECIST 1.1 for target lesions: PD is at least a 20% increase in sum LD, taking as reference the smallest sum on study with at least 5 mm absolute increase. For non-target lesions, progression-free means no new lesions or unequivocal progression on existing non-target lesions or not evaluated.

Groups in this outcome

Liposarcomas

* Participants will receive eribulin intravenously on Day 1 and Day 8 * Pembrolizumab is administered intravenously Day 1, on a 21-day cycle Eribulin: The ability of chemotherapy to kill cancer cells depends on its ability to halt cell division. Usually, the drugs work by damaging the RNA or DNA that tells the cell how to copy itself in division. If the cells are unable to divide, they die. The faster the cells are dividing, the more likely it is that chemotherapy will kill the cells, causing the tumor to shrink. They also induce cell suicide (self-death or apoptosis). Pembrolizumab: The drug blocks the PD-1 receptor, preventing binding and activation of PD-L1 and PD-L2. This mechanism causes the activation of T-cell mediated immune responses against tumor cells.

Leiomyosarcomas

* Participants will receive eribulin intravenously on Day 1 and Day 8 * Pembrolizumab is administered intravenously Day 1, on a 21-day cycle Eribulin: The ability of chemotherapy to kill cancer cells depends on its ability to halt cell division.

Pembrolizumab: The drug blocks the PD-1 receptor, preventing binding and activation of PD-L1 and PD-L2. This mechanism causes the activation of T-cell mediated immune responses against tumor cells.

Undifferentiated Pleomorphic Sarcomas
