About
This phase II trial studies how well cabozantinib s-malate works in treating patients with endometrial cancer that has come back (recurrent) or has spread to other places in the body (metastatic). Cabozantinib s-malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.
Full description
PRIMARY OBJECTIVES:
I. Determine efficacy of single agent cabozantinib s-malate (cabozantinib) in women previously receiving one line of chemotherapy for metastatic endometrial cancer or with progression within 12 months of completing adjuvant therapy, with co-primary endpoints of objective response rate by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and progression-free-survival at 12 weeks (PFS).
SECONDARY OBJECTIVES:
I. Correlation of clinical response with baseline molecular status of archival tumor (hepatocyte growth factor receptor [c-met] amplification & mutation status) and overall survival.
OUTLINE:
Patients receive cabozantinib s-malate orally (PO) once daily (QD) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 4 weeks or every 6 months.

Inclusion criteria
- Patients must have histologically or cytologically confirmed metastatic endometrial cancer; eligible histologies for the experimental cohort are: endometrioid or serous; eligible histologies for the exploratory cohort are: carcinosarcoma, clear cell, mixed, adenosquamous and any other rare sub-type of endometrial cancer
- Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as >= 10 mm with computed tomography (CT) scan, magnetic resonance imaging (MRI), or calipers by clinical exam and >= 15 mm in short axis for nodal lesions; patients must have radiographic evidence of disease progression following the most recent line of treatment
- Prior therapy: Eligible subjects must have had 1 line of systemic cytotoxic treatment; this may be adjuvant therapy with documented progression within 12 months of completion, or 1 line of cytotoxic therapy for metastatic disease; NOTE: eligible patients are allowed up to 2 lines of systemic cytotoxic treatment, of which only 1 line is allowed for metastatic disease; the acceptance of progression within 12 months of adjuvant is part inclusion to not require patient to re-challenge with chemotherapy (chemo) if they progressed soon after adjuvant therapy; prior hormonal therapy for metastatic/recurrent disease is also allowed; prior targeted therapy not directed against cMET or vascular endothelial growth factor (VEGF) pathways is allowed
- Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60%)

- Women of childbearing potential must have a negative pregnancy test at screening; women of childbearing potential include women who have experienced menarche and who have not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or are not postmenopausal; postmenopausal is defined as amenorrhea >= 12 consecutive months; note: women who have been amenorrheic for 12 or more months are still considered to be of childbearing potential if the amenorrhea is possibly due to prior chemotherapy, antiestrogens, ovarian suppression or any other reversible reason
- Women of child-bearing potential must agree to use adequate contraception prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while she is participating in this study, she should inform her treating physician immediately; sexually active subjects must agree to use medically accepted barrier methods of contraception (e.g., male or female condom) during the course of the study and for 4 months after the last dose of study drug(s), even if oral contraceptives are also used; all subjects of reproductive potential must agree to use both a barrier method and a second method of birth control during the course of the study and for 4 months after the last dose of study drug(s)
- Patients must consent to analysis on archival tissue; if archival sample is not available, a sufficient tumor biopsy can be performed a minimum of 28 days prior to start of treatment if felt to be clinically reasonable
- Ability to understand and the willingness to sign a written informed consent document
