Brief Summary:
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.

Detailed Description:

PRIMARY OBJECTIVES:

I. 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:

I. 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:

I. 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.

Primary Outcome Measures :
  1. Change in androgen receptor (AR) receptor expression [ Time Frame: Baseline to 26-28 days after treatment initiation ]
    Summary statistics and boxplots will be used to describe the distributions of expression of AR and its downstream signaling effectors. We will similarly describe the change from baseline for AR and its downstream signaling effectors. If the usual normality assumptions hold we will use a paired t-test to test for significant changes in expression from baseline to follow-up assessment, otherwise we will test for changes with the Wilcoxon signed-rank test. For those variables measured on a nominal scale we will cross-tabulate values at baseline and follow-up assessments, and we will test for differences between baseline and follow-up assessments with a Fisher's exact test. A time dependent covariate analysis may be conducted to assess the impact of changes in biomarker expression on progression free survival (PFS) and overall survival (OS).

  2. Change in AR receptor activation [ Time Frame: Baseline to 26-28 days after treatment initiation ]
    Summary statistics and boxplots will be used to describe the distributions of expression of AR and its downstream signaling effectors. We will similarly describe the change from baseline for AR and its downstream signaling effectors. If the usual normality assumptions hold we will use a paired t-test to test for significant changes in expression from baseline to follow-up assessment, otherwise we will test for changes with the Wilcoxon signed-rank test. For those variables measured on a nominal scale we will cross-tabulate values at baseline and follow-up assessments, and we will test for differences between baseline and follow-up assessments with a Fisher's exact test. A time dependent covariate analysis may be conducted to assess the impact of changes in biomarker expression on PFS and OS.

  3. Change expression of AR-related genes [ Time Frame: Baseline to 26-28 days after treatment initiation ]
    Summary statistics and boxplots will be used to describe the distributions of expression of AR and its downstream signaling effectors. We will similarly describe the change from baseline for AR and its downstream signaling effectors. If the usual normality assumptions hold we will use a paired t-test to test for significant changes in expression from baseline to follow-up assessment, otherwise we will test for changes with the Wilcoxon signed-rank test.

A time dependent covariate analysis may be conducted to assess the impact of changes in biomarker expression on PFS and OS.

  4. Change in sequencing of AR-related pathway members [ Time Frame: Baseline to 26-28 days after treatment initiation ]
    Summary statistics and boxplots will be used to describe the distributions of expression of AR and its downstream signaling effectors. We will similarly describe the change from baseline for AR and its downstream signaling effectors. If the usual normality assumptions hold we will use a paired t-test to test for significant changes in expression from baseline to follow-up assessment, otherwise we will test for changes with the Wilcoxon signed-rank test.

A time dependent covariate analysis may be conducted to assess the impact of changes in biomarker expression on PFS and OS.

  5. Rate of toxicity [ Time Frame: 21 days ]
    Defined by dose-limiting toxicities (DLT) experienced during safety lead-in where a posterior probability DLT rate is > 30%.

  6. Feasibility [ Time Frame: Up to 1 year ]
    Defined as percentage (%) of patients that receive three courses of chemotherapy. Will be estimated with 95% confidence interval.


Secondary Outcome Measures :
  1. OS [ Time Frame: Up to 1 year ]
    Estimated using the Kaplan Meier method. Will use Cox proportional hazards regression to model PFS and OS as functions of mutation status and protein expression, and we will estimate hazard ratios with 95% confidence intervals. A time dependent covariate analysis may be conducted to assess the impact of changes in biomarker expression on PFS and OS.

  2. PFS [ Time Frame: Up to 1 year ]
    We will use Cox proportional hazards regression to model PFS and OS as functions of mutation status and protein expression, and we will estimate hazard ratios with 95% confidence intervals. A time dependent covariate analysis may be conducted to assess the impact of changes in biomarker expression on PFS and OS.

  3. Objective tumor response (complete response/partial response) rate [ Time Frame: Up to 1 year ]
    We will use Cox proportional hazards regression to model PFS and OS as functions of mutation status and protein expression, and we will estimate hazard ratios with 95% confidence intervals. A time dependent covariate analysis may be conducted to assess the impact of changes in biomarker expression on PFS and OS.
