Clinical Trial Summary

This phase II trial studies how well trametinib and v-akt murine thymoma viral oncogene homolog 1 (Akt) inhibitor GSK2141795 work in treating patients with triple-negative breast cancer (breast cancer cells that do not have estrogen receptors, progesterone receptors, or large amounts of human epidermal growth factor receptor 2 [HER2/neu] protein) that has spread to other places in the body. Trametinib and Akt inhibitor GSK2141795 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.


Description:

PRIMARY OBJECTIVES:

I. To assess the anti-tumor activity associated with trametinib monotherapy in patients with triple negative breast cancer (TNBC).

SECONDARY OBJECTIVES:

I. To assess the anti-tumor activity associated with trametinib in combination with AKT inhibitor GSK2141795 after progression on trametinib in patients with metastatic TNBC.

II. To determine the progression-free survival following the initiation of treatment with trametinib monotherapy in patients with metastatic TNBC.

III. To determine the progression-free survival following the initiation of treatment with trametinib in combination with GSK2141795 in patients with metastatic TNBC.

IV. To determine the overall survival following the initiation of treatment with trametinib with GSK214179 in patients with metastatic TNBC.

V. To determine the nature and degree of toxicities associated with trametinib monotherapy and trametinib in combination with GSK2141795 in patients with metastatic TNBC.

VI. To determine the biomarker potential of phosphatase and tensin homolog (PTEN) to predict response to single agent trametinib.

VII. To determine molecular markers of sensitivity and resistance to trametinib monotherapy and trametinib in combination with GSK2141795 in patients with metastatic TNBC.

OUTLINE:

PART 1: 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 who experience disease progression continue to Part 2.

PART 2: Patients receive trametinib as in Part 1 and also receive 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 52 weeks.

Outcome

Type Measure Description Time frame Safety issue
Other Predictive Value of PTEN and Other Biomarkers on Patient Outcome (Survival, ORR, and CBR) At time of disease progression, assessed up to 52 weeks
Other Protein Intensity Fold-change Ratios Assessed by Reverse Phase Protein Assay Intensity Values Ratios between tumors sampled prior to initiating trametinib single agent treatment and at time of progression (TOP) on either single agent trametinib or the combination (TOP/pre-treat ratio), will be calculated. These ratios will be median-centered and clustered using Cluster 2.0 software. Student's t-test for differences between average protein intensity ratios at these intervals will be calculated using Microsoft Excel by grouping all the ratios for individual clusters. Up to 52 weeks
Primary Objective Response Rate (ORR), Defined as the Proportion of Patients Who Have Had a Partial Response (PR) or Complete Response (CR) (RECIST 1.1 Based) Within the First 6 Months After Initiation of Therapy With Trametinib Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR. 6 months
Secondary Clinical Benefit Rate (CBR = CR+PR+Stable Disease [SD]) The clinical benefit rate (CR+PR+SD) will be reported for patients after Part 1 and after Part 2. Up to 52 weeks
Secondary Duration of Objective Response Summary statistics of duration of response for patients with objective response up to 52 weeks
Secondary Incidence of Adverse Events That Are Classified as Either Possibly, Probably, or Definitely Related to Study Treatment Incidence of adverse events for patients that are classified as either possibly, probably, or definitely related to study treatment graded by National Cancer Institute (NCI) CTCAE v4.0 Up to 52 weeks
Secondary Incidence of Severe (Grade 3+) Adverse Events or Toxicities Graded Per NCI CTCAE Version 4.0 NCI CommonTerminology Criteria for Adverse Events (CTCAE) version 4.0 was utilized for grading incidence of toxicities (grade 3+). Up to 52 weeks
Secondary Overall Survival The Kaplan-Meier method will be used to estimate overall survival distribution. Start date of the treatment to the date of the event (i.e., death) or the date of last follow-up to evaluate that event, assessed up to 52 weeks
Secondary Progression-free Survival The Kaplan-Meier method will be used to estimate progression-free survival distribution. The duration of time from start of treatment to time of progression or death, whichever comes first, assessed up to 52 weeks
Secondary Proportion of Patients Who go Off Treatment Due to Adverse Reactions The proportion of patients who go off treatment due to adverse reactions or even those who refuse further treatment for lesser toxicities that inhibit their willingness to continue participation on the trial was captured. These tolerability measures were assessed within each of the treatment parts independently. All patients who have received at least one dose of any of the therapeutic agents was evaluable for toxicity and tolerability. Up to 52 weeks
Secondary Proportion of Patients Who Refuse Further Treatment for Lesser Toxicities That Inhibit Their Willingness to Continue Participation on the Trial Up to 52 weeks
Secondary Tolerability of the Regimen Defined as the Number of Patients Who Required Dose Modifications and/or Dose Delays Up to 52 weeks
