This phase II trial studies how well dalantercept works in treating patients with recurrent or persistent endometrial cancer. Dalantercept may stop the growth of endometrial cancer by blocking blood flow to the tumor.

Official Title




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) when treated with dalantercept.

II. To determine the nature and degree of toxicity of dalantercept in this cohort of patients.


I. To estimate progression-free survival (PFS) and overall survival (OS) of patients with persistent or recurrent endometrial cancer treated with dalantercept.


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: This is a multicenter study.

Patients receive dalantercept subcutaneously (SC) on day 1. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

Blood and tumor tissue samples are collected for VEGF, FGF, PDGF, TGF-β, ALK1, CD105, ALK1, BMP9, and BMP10 protein analysis and gene expression by IHC, ELISA, and reverse transcriptase polymerase chain reaction (RT-PCR).

After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 3 years.

  • All patients must have measurable disease; measurable disease is defined by Response Evaluation Criteria in Solid Tumors(RECIST) (version 1.1) as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded); each lesion must be ≥ 10 mm when measured by computed tomography (CT),magnetic resonance imaging (MRI), or caliper measurement by clinical exam; or ≥ 20 mm when measured by chest x-ray; lymph nodes must be> 15 mm in short axis when measured by CT or MRI
  • Patients must have at least one "target lesion" to be used to assess response on this protocol as defined by RECIST version 1.1; tumors within a previously irradiated field will be designated as "non-target" lesions unless progression is documented or a biopsy is obtained to confirm persistence at least 90 days following completion of radiation therapy
  • Patients must not be eligible for a higher priority Gynecologic Oncology Group (GOG)protocol, if one exists; in general, this would refer to any active GOG phase III protocol or rare tumor protocol for the same patient population
  • Patients who have received one prior regimen must have a GOG performance status of 0,1, or 2; patients who have received two prior regimens must have a GOG performance status of 0 or 1
  • Recovery from effects of recent surgery, radiotherapy, or chemotherapy
  • Patients should be free of active infection requiring antibiotics (with the exception of uncomplicated urinary tract infection [UTI])
  • Any hormonal therapy directed at the malignant tumor must be discontinued at least one week prior to registration

  • Any prior radiation therapy must be discontinued at least four weeks prior to registration
  • At least 4 weeks must have elapsed since the patient underwent any major surgery(e.g., major: laparotomy, laparoscopy); there is no delay in treatment for minor procedures (e.g., central venous access catheter placement)
  • Prior therapy
  • Patients must have had one prior chemotherapeutic regimen for management of endometrial carcinoma. Initial treatment may include chemotherapy, chemotherapy and radiation therapy, and/or consolidation/maintenance therapy; chemotherapy administered in conjunction with primary radiation as a radio-sensitizer WILL be counted as a systemic chemotherapy regimen
  • Patients are allowed to receive, but are not required to receive, one additional cytotoxic regimen for management of recurrent or persistent disease
  • Patients must have NOT received any non-cytotoxic (biologic or targeted)agent(s) for management of recurrent or persistent disease; prior non-cytotoxic(biologic or targeted) agent(s) is allowed as part of initial treatment; prior hormonal therapy is allowed, but must be discontinued at least one week prior to registration
