Trametinib in Treating Patients With Recurrent or Progressive Low-Grade Ovarian Cancer or Peritoneal Cavity Cancer

A Randomized Phase II/III Study to Assess the Efficacy of Trametinib (GSK 1120212) in Patients With Recurrent or Progressive Low-Grade Serous Ovarian Cancer or Peritoneal Cancer

Status: Completed
Phase: Phase 2 / Phase 3

Summary

This phase II/III trial studies how well trametinib works and compares it to standard treatment with either letrozole, tamoxifen, paclitaxel, pegylated liposomal doxorubicin, or topotecan in treating patients with low-grade ovarian cancer or peritoneal cavity cancer that has come back (recurrent), become worse (progressive), or spread to other parts of the body. Trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether trametinib is more effective than standard therapy in treating patients with ovarian or peritoneal cavity cancer.

Detailed description

PRIMARY OBJECTIVE: I. To estimate the progression-free survival (PFS) hazard ratio of trametinib compared to that of "commercially available therapies" consisting of one of five commercially available agents in women with recurrent low-grade serous carcinoma of the ovary or peritoneum previously treated with platinum-based chemotherapy. SECONDARY OBJECTIVES: I. To determine the nature, frequency and maximum degree of toxicity as assessed by Common Terminology Criteria for Adverse Events (CTCAE) version (v) 4 for each treatment arm. II. To determine the quality of life, as assessed by the Functional Assessment of Cancer Therapy-Ovarian (FACT-O). IIa. To compare trametinib to the control arm with regard to patients' self-reported acute (up to post-cycle 6) quality of life as measured by the FACT-O-Trial Outcome Index (TOI). IIb. To compare trametinib to the control arm with regard to patients' self-reported acute (up to post-cycle 6) neurotoxicity as measured by the FACT-Gynecologic Oncology Group (GOG)-Neurotoxicity (NTX). III. To estimate the objective response rate (RR) of patients in each treatment arm. IV. To test whether high expression of pERK, as quantified by immunohistochemistry (IHC), is associated with better prognosis (RR or PFS) among patients receiving the randomized treatment. V. To test whether genetic changes associated with MAPK pathway activation (KRAS, NRAS, HRAS, BRAF, MEK, ERBB2 or NF1) are associated with improved prognosis (RR or PFS) among patients receiving the randomized treatment. OUTLINE: Patients are randomized to 1 of 2 treatment arms. ARM A: Patients receive clinician's choice of either letrozole orally (PO) once daily (QD) on days 1-28, tamoxifen citrate PO twice daily (BID) on days 1-28, paclitaxel intravenously (IV) over 1 hour on days 1, 8, and 15, pegylated liposomal doxorubicin hydrochloride (PLD) IV over 1 hour on day 1, or topotecan IV over 30 minutes on days 1, 8, and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients developing progressive disease may cross over to Arm B. ARM B: Patients receive trametinib PO QD on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months for 2 years, every 6 months for 3 years, and then annually for 5 years.
