Brief summary
This phase II trial studies how well dalantercept works in treating patients with endometrial cancer that has come back or is persistent. Dalantercept may stop the growth of endometrial cancer by blocking blood flow to the tumor.
Detailed description
PRIMARY OBJECTIVES: I. To estimate the proportion of patients with persistent or recurrent endometrial cancer who survive progression-free for at least 6 months and the proportion of patients who have objective tumor response (complete or partial), treated with dalantercept (ACE-041). II. To determine the nature and degree of toxicity of dalantercept in this cohort of patients. SECONDARY OBJECTIVES: I. To estimate progression-free survival (PFS) and overall survival (OS) of patients with persistent or recurrent endometrial cancer treated with dalantercept. TERTIARY OBJECTIVES: I. To measure the expression of vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF), platelet-derived growth factor (PDGF), transforming growth factor-beta (TGF-β), activin receptor-like kinase 1 (ALK1), endoglin (CD105), and other markers via immunohistochemistry (IHC) and determine if there is correlation between expression and clinical response to treatment. II. To determine the correlation between ALK1 gene expression, other markers, and clinical response to treatment. III. To determine the correlation between concentration of VEGF, bone morphogenetic protein 9 (BMP9), bone morphogenetic protein 10 (BMP10), and ALK1 in pre-cycle 1 plasma using an enzyme-linked immunosorbent assay (ELISA), and clinical response to treatment. IV. To correlate somatic mutations in candidate genes with response to therapy. OUTLINE: Patients receive dalantercept subcutaneously (SC) on day 1. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 3 years.

Duration of Progression-free Survival
Progression-free survival is defined as the duration alive from study entry until progression is documented or death, whichever comes sooner. Progressive disease is defined as at least a 5 mm absolute increase and a 20% relative increase in the sum of measurable target lesions' longest dimensions relative to the smallest sum at baseline or on study or the appearance of new lesions or unequivocal progression of existing non-target lesions.
Time frame: CT scan or MRI were to assess progression every other cycle for the first 6 months; every three months thereafter; and any time if clinically indicated based on symptoms or physical signs suggestive of progressive disease.
Population: All eligible and treated patients.

Secondary
Duration of Survival
Duration of survival is defined as the duration alive from study entry until death or last contact.
Time frame: Patients are followed every three months for the first two years and then every six months for the next three years.
Population: All eligible and treated patients
| Arm | Measure | Value (MEDIAN) |

| Dalantercept | Duration of Survival | 14.5 months |
Secondary
Progression-free Survival at 6 Months
Progression-free survival is defined as the duration alive from study entry until progression is documented or death, whichever comes sooner. Progressive disease is defined as at least a 5 mm absolute increase and a 20% relative increase in the sum of measurable target lesions' longest dimensions relative to the smallest sum at baseline or on study or the appearance of new lesions or unequivocal progression of existing non-target lesions. Disease progression within 6 months of study entry or death within 6 months of study entry and prior to disease progression counts as an event for progression-free survival at 6 months.
Time frame: : CT scan or MRI were to assess progression every other cycle for the first 6 months; every three months thereafter; and any time if clinically indicated based on symptoms or physical signs suggestive of progressive disease.
Population: All eligible and treated patients
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Dalantercept | Progression-free Survival at 6 Months | 17.9 percentage of participants |
