Brief Summary:
This pilot, phase II trial studies how well everolimus and letrozole work in treating patients with hormone receptor positive ovarian, fallopian tube, or primary peritoneal cavity cancer that has come back. Everolimus and letrozole may stop the growth of tumor cells by blocking some the enzymes needed for cell growth.

Detailed Description:

PRIMARY OBJECTIVES:

I. Demonstrate that the combination of letrozole and everolimus leads to a higher percentage of patients who are free of progression at 12 weeks (PFS 12) as compared with that observed in a previously reported phase 2 trial of letrozole alone for relapsed ovarian carcinomas.

SECONDARY OBJECTIVES:

I. Cancer antigen (CA)-125 response, progression-free survival (PFS), overall survival (OS), the confirmed response rate, and adverse events.

TERTIARY OBJECTIVES:

I. Identify molecular biomarkers associated with a response to treatment with letrozole and everolimus in patients with relapsed ovarian carcinomas.

II. Develop and determine if response rates to letrozole and everolimus in patient derived xenograft (PDX) avatars correlate to responses noted in the patients.

OUTLINE:

Patients receive everolimus orally (PO) once daily (QD) and letrozole PO 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 6 months for 2 years.

Primary Outcome Measures :
  1. Proportion of patients alive and PFS12 [ Time Frame: 12 weeks ]
    The proportion of PFS12 successes will be estimated by the number of successes divided by the total number of evaluable patients. Ninety-five percent confidence intervals for the true success proportion will be calculated according to the exact binomial method.


Secondary Outcome Measures :
  1. CA-125 response, defined as a 50% or greater reduction in baseline CA-125 [ Time Frame: Up to 2 years ]
    The treatment of letrozole and everolimus will be considered promising, based on CA-125, if the observed CA-125 response rate is 30% or more.

  2. Confirmed response rate, estimated using RECIST 1.1 criteria [ Time Frame: Up to 24 weeks ]
    A confirmed tumor response is defined to be either a complete response or partial response noted as the objective status on 2 consecutive evaluations at least 4 weeks apart.

  3. Incidence of adverse events, graded according to National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0 [ Time Frame: Up to 30 days post-treatment ]
    The maximum grade for each type of adverse event (AE) will be recorded for each patient, and frequency tables will be reviewed to determine AE patterns.

  4. OS [ Time Frame: Time from registration to death from any cause, assessed up to 2 years ]
    OS will be estimated using the method of Kaplan-Meier.

  5. PFS [ Time Frame: Time from registration to the first of either disease progression or death from any cause, assessed up to 2 years ]
    PFS will be estimated using the method of Kaplan-Meier.


Other Outcome Measures:
  1. Expression of molecular biomarkers associated with a response to treatment with letrozole and everolimus in patients with relapsed ovarian carcinomas [ Time Frame: 28 days following treatment initiation ]
    The Fisher's Exact test will be used to measure the associations.

  2. Response rates to letrozole and everolimus in PDX avatars [ Time Frame: 28 days following treatment initiation ]
    Will determine if response rates to letrozole and everolimus in PDX avatars correlate to responses noted in the patients. The Fisher's Exact test will be used to measure the associations.

  3. Responsiveness of tumors to letrozole and everolimus [ Time Frame: 28 days following treatment initiation ]
    "Response" will be defined as tumors with at least a 50% reduction in tumor volume at study end. "Unresponsive" will be defined as tumors with less than 10% tumor volume reduction at study end. Intermediate values will be defined as "Stable". Tumor growth curves will be plotted graphically and notated to indicate the outcome status of the originating patients. End of study tumor volumes will be correlated with outcome status of the originating patient as well. The Fisher's Exact test will be used to measure the associations.
