Brief summary

This randomized phase II trial studies how well temsirolimus with or without megestrol acetate and tamoxifen citrate works in treating patients with endometrial cancer that has spread to other places in the body and usually cannot be cured or controlled with treatment, has returned after a period of improvement, or is persistent. Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Estrogen can cause the growth of endometrial cancer cells. Hormone therapy using megestrol acetate and tamoxifen citrate may fight endometrial cancer by blocking the use of estrogen by the tumor cells. It is not yet known whether temsirolimus is more effective when given alone or together with megestrol acetate and tamoxifen citrate in treating endometrial cancer.

Detailed description

PRIMARY OBJECTIVES: I. To determine the response rate of patients with advanced, persistent, or recurrent endometrial cancer when treated with each of the arms of the trial; the proposed arms are: Arm #1 temsirolimus intravenously (IV) weekly, Arm #2 megestrol (megestrol acetate)/tamoxifen (tamoxifen citrate) plus temsirolimus IV weekly. II. Time to progression and number of patients remaining on study therapy at 24 weeks. SECONDARY OBJECTIVE: I. To describe the toxicities of each of the arms of the trial when used for patients with advanced/metastatic endometrial cancer. TERTIARY OBJECTIVES: I. Explore whether immunohistochemical expression of hormone receptors (estrogen receptor-alpha, estrogen receptor-beta, progesterone receptors-A, progesterone receptor-B and the alternative estrogen receptor, G protein-coupled estrogen receptor \[GPR\]-30) or components of the mammalian target of rapamycin (mTOR) signaling pathway (normal and mutant phosphatase and tensin homolog \[PTEN\], total and phosphorylated v-akt murine thymoma viral oncogene homolog 1 \[Akt\] as well as total and phosphorylated p70S6 kinase) are associated with treatment, outcome or clinical characteristics. II. Explore whether single nucleotide polymorphisms (SNPs) in the FK506-binding protein 12-rapamycin-associated protein 1 (FRAP1) and regulatory associated protein of mTOR (RAPTOR) genes, mutations in phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA), PTEN and paxillin or copy number abnormalities in PTEN and paxillin are associated with treatment, outcome or clinical characteristics. OUTLINE: Patients are randomized to 1 of 2 treatment arms. (Closed to accrual as of 11/22/2010) ARM I: Patients receive temsirolimus IV over 30 minutes once weekly for 6 weeks. Courses repeat every 6 weeks in the absence of disease progression or unacceptable toxicity. ARM II (Closed to accrual as of 12/21/2009): Patients receive temsirolimus as in Arm I and megestrol acetate orally (PO) twice daily (BID) for 3 weeks alternating with tamoxifen citrate PO BID for 3 weeks. Courses repeat every 6 weeks in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up for 1 year.
