Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • Women only
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Patients must have a histologically confirmed diagnosis (by either primary surgical specimen or biopsy for recurrence) of advanced stage (stage III or IV) or recurrent endometrioid endometrial cancer
  • Measurable disease (at least one measurable lesion) IS required; a measurable lesion is one 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) scan, 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 Response Evaluation Criteria in Solid Tumors (RECIST); 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
  • Patient with an Eastern Cooperative Oncology Group (ECOG) performance status =< 1
  • Life expectancy of greater than 3 months in the opinion of the principal investigator
  • 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 other prior therapy directed at the malignant tumor, including immunologic agents, must be discontinued at least three weeks prior to registration
  • PRIOR THERAPY: Patients should have had NO prior chemotherapy agents for advanced or recurrent endometrial cancer; prior chemotherapy administration in conjunction with primary radiation therapy as a radiosensitizer would NOT exclude a patient from participation in this trial
  • Absolute neutrophil count (ANC) >= 1,500/mcl, equivalent to Common Terminology Criteria (Common Terminology Criteria for Adverse Events [CTCAE] version [v] 4.03) grade 1
  • Platelets >= 100,000/mcl
  • Calculated creatinine clearance (Cockcroft-Gault formula) > 50 ml/min OR 24-hour urine creatinine clearance > 50 ml/min
  • Bilirubin =< 1.5 x upper limit of normal (ULN) (CTCAE v4.03 grade 1; in patients with known Gilbert syndrome, a total bilirubin =< 3.0 x ULN, with direct bilirubin =< 1.5 x ULN)
  • Aspartate aminotransferase (AST) and alkaline phosphatase =< 2.5 x ULN (CTCAE v4.03 grade 1; AST and alanine aminotransferase [ALT] =< 3 x ULN [or =< 5.0 x ULN if hepatic metastases are present])
  • Neuropathy (sensory and motor) =< CTCAE v4.03 grade 1
  • Prothrombin time (PT) such that international normalized ratio (INR) is =< 1.5 (or an in-range INR, usually between 2 and 3, if a patient is on a stable dose of therapeutic warfarin) and a partial thromboplastin time (PTT) =< 1.5 times the institutional upper limit of normal; patients receiving low molecular weight heparin for the prevention or treatment of venous thromboembolic disease are eligible if considered clinically stable on their regimen
  • Patients must have signed an approved informed consent
  • Because no dosing or adverse event data are currently available on the use of enzalutamide in combination with carboplatin and paclitaxel in patients <18 years of age, children are excluded from this study.

About this study

Official title: A Phase II Study With a Limited Safety Lead-In of Enzalutamide in Combination With Carboplatin and Paclitaxel in Advanced Stage or Recurrent Endometrioid Endometrial Cancer

This phase II trial studies how well enzalutamide, carboplatin, and paclitaxel work in treating patients with endometrioid endometrial cancer that is stage III-IV or has come back. Androgens can cause the growth of endometrioid endometrial cancer. Antihormone therapy, such as enzalutamide may lessen the amount of androgen made by the body. Drugs used in chemotherapy, such as carboplatin and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving enzalutamide, carboplatin, and paclitaxel may work better in treating patients with endometrioid endometrial cancer.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine the clinical activity of combination enzalutamide, carboplatin and paclitaxel represented as:

Ia. Objective tumor response (complete response [CR] + partial response [PR]). Ib. The proportion of patients who survive progression-free for at least 6 months after initiating therapy.

II. To quantify protein and phosphoprotein expression of androgen receptor (AR) and AR-response genes following enzalutamide treatment in match-paired pre and post treatment tumor biopsies.

III. To determine the safety and feasibility of daily enzalutamide given in combination with carboplatin and paclitaxel in women with advanced stage or recurrent endometrial cancer.

SECONDARY OBJECTIVES:

  1. Determine median response duration. II. Estimate progression free survival and overall survival. III. Evaluate for presence of pharmacokinetic interaction between enzalutamide and paclitaxel.

EXPLORATORY OBJECTIVES:

  1. Correlate molecular results, including AR receptor expression and activation, to clinical endpoints.

II. Identify potential agents to synergize with enzalutamide based on pathways activated after enzalutamide treatment.

OUTLINE:

Patients receive enzalutamide orally (PO) once daily (QD) alone on days 1-28. Patients then receive enzalutamide PO QD on days 1-21, paclitaxel intravenously (IV) over 3 hours on day 1, and carboplatin IV over 1 hour on day 1. Treatment repeats every 21 days for 6-9 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for up to 1 year.
