A Phase 1 interventional study of Laboratory Biomarker Analysis and Trametinib in Endometrial Adenocarcinoma, Endometrial Clear Cell Adenocarcinoma and Endometrial Mixed Cell Adenocarcinoma, sponsored by National Cancer Institute (NCI). Completed at 22 sites in United States. Open to female participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2020-10-14.

This randomized phase I trial studies how well trametinib with or without GSK 2141795 (protein kinase B [Akt] inhibitor GSK2141795) works in treating patients with endometrial cancer that has come back (recurrent) or does not go to remission despite treatment (persistent). Trametinib and Akt inhibitor GSK2141795 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 a more effective treatment for endometrial cancer when given with or without ATK inhibitor GSK2141795.
PRIMARY OBJECTIVES:
I. To assess the relative activity of trametinib (mitogen-activated protein kinase [MEK] inhibitor) alone or in combination with GSK2141795 (AKT inhibitor) for patients with recurrent or persistent endometrial cancer by progression-free survival. (Phase II) II. To determine the frequency and severity of adverse events as assessed by Common Terminology Criteria for Adverse Events (CTCAE). (Phase II) III. To determine the tolerability of the combination regimen of trametinib and GSK2141795 through determination of dose-limiting toxicity in a two-stage safety lead in study. (Safety assessment lead-in)
SECONDARY OBJECTIVES:
I. To estimate the association between baseline Kirsten rat sarcoma viral oncogene homolog (KRAS) status and clinical activity (e.g. response and progression-free survival [PFS]) for patients with recurrent or persistent endometrial cancer who are treated with trametinib alone or in combination with GSK2141795.
II. To estimate overall survival (OS) of patients with recurrent or persistent endometrial cancer treated with trametinib therapy alone (excluding patients who cross-over) and trametinib/GSK2141795 combination therapy in the two subgroups of patients defined above.
III. Prognostic factors will be examined for associations with patients who do not crossover.
IV. To estimate objective response and response duration associated with trametinib therapy and trametinib/GSK2141795 combination therapy in the two subgroups of patients defined above.
V. To estimate the relative proportion of patients responding or have 6-month PFS on the therapies administered on this study with those studies that may serve as a historical control.
TERTIARY OBJECTIVES:
I. To estimate the association between baseline genomic biomarkers in the phosphatidylinositol 3 kinase (PI3K)/AKT pathway and clinical activity (e.g. response and PFS) in two subgroups of patients defined above with recurrent or persistent endometrial cancer who are treated with trametinib alone or in combination with GSK2141795.
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive trametinib orally (PO) once daily (QD) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients achieving disease progression may cross over to Arm II.
ARM II: Patients receive trametinib PO QD and Akt inhibitor GSK2141795 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 3 months for 2 years and then every 6 months for 3 years.
2,004 studies on the registry are indexed under Adenocarcinoma; 375 are open to participants now.
This study's enrollment of 26 is below the median of 45 across 1,553 interventional studies indexed under Adenocarcinoma.

Patients must have recurrent or persistent endometrial carcinoma, which is refractory to curative therapy or established treatments; histologic confirmation of the original primary tumor is required
Formalin-fixed, paraffin-embedded tumor tissue must be submitted to Baylor College of Medicine (BCM) - Cancer Genetics Laboratory for Clinical Laboratory Improvement Amendments (CLIA)-certified KRAS mutation testing; results must be reported on the eligibility checklist during registration in order to receive treatment assignment
Patients MAY HAVE received non-cytotoxic (biologic or targeted) agent(s) as part of initial treatment and/or for management of recurrent or persistent disease, with the below stated exceptions (see NOTE below); prior hormonal therapy is allowed, but must be discontinued at least one week prior to registration

PFS by regimen administered using RECIST version 1.1 (Phase II)
The null hypothesis will be tested against the alternative with a stratified log-rank test.
Time frame: The duration of time from study entry to time of progression or death, whichever occurs first, assessed up to 5 years
Frequency of adverse events defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related
Reported using the descriptions found in the National Cancer Institute (NCI) CTCAE version 4.0.
Time frame: Up to 30 days after last study treatment
Severity of adverse events, graded using the NCI CTCAE version 4.0 (Safety assessment and phase II)
Time frame: Up to 30 days after last study treatment
Incidence of dose-limiting toxicity (DLT), graded according to the current version of NCI CTCAE (Safety assessment)
If 3 or fewer patients out of 12 experience DLTs in course 1 (including treatment delays for course 2 of greater than 2 weeks due to toxicities), then the regimen will be deemed safe for administration in the phase II study. If 4 or more patients out of 12 experience DLTs, then the regimen will be declared unsafe.
Time frame: 28 days
KRAS status (mutant or wild type)
The impact of KRAS mutation on response and PFS will be assessed according to the regimens administered. Given the possibility that KRAS+ patients may be small in number (20%), these comparisons may be informal (e.g. Kaplan-Meier survival estimates).

Time frame: Up to 5 years
PFS by regimen
Time frame: The duration of time from study entry to time of progression or death, whichever occurs first, assessed up to 5 years

Baseline genomic biomarkers
Baseline genomic biomarkers will be assessed against response, PFS, OS (excluding crossovers) by regimen and KRAS status through odds ratios and proportional hazards estimates where possible.
