The primary objective of this multicenter, randomized phase II trial is to assess the efficacy, as measured by progression-free survival (PFS), of lenvatinib compared to doxorubicin in advanced or recurrent endometrial cancer.

The main secondary objective is to evaluate the predictive value of Ang-2 on lenvatinib activity and establishing a cutoff value as potential selection criteria for phase III.

Other secondary objectives are to assess the tolerability and safety of lenvatinib in this setting and overall survival, response and disease control.

Inclusion Criteria:
