Brief Summary:
This phase Ib trial studies the side effects of pembrolizumab and trametinib in treating patients with non-small cell lung cancer and KRAS gene mutations that has spread to other places in the body. Monoclonal antibodies, such as pembrolizumab, may interfere with the ability of tumor cells to grow and spread. Trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving pembrolizumab and trametinib may work better in treating patients with non-small cell lung cancer.

Primary Outcome Measures :
  1. Incidence of dose-limiting toxicity (DLT) of pembrolizumab and trametinib per National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events version 4.0 [ Time Frame: Up to 6 weeks ]
    The occurrence of toxicities during the first two cycles (i.e. after completion of the lead in cycle and the first cycle where both pembrolizumab and trametinib are administered) will be considered a DLT, if judged by the Investigator to be possibly, probably or definitely related to study drug administration. Adverse events will be summarized descriptively by type and by severity, with number and relative frequency calculated for all non-zero occurrences.


Secondary Outcome Measures :
  1. Overall response rate (ORR) [ Time Frame: Up to 3 years ]
    Association with response rate will be summarized descriptively by presenting the mean, standard deviation (SD), and other characteristics of molecular and immune measures, stratified by response status. Will assess whether one arm has superior ORR, using logistic regression analysis to control for clinical covariates.

  2. Progression-free survival (PFS) [ Time Frame: Up to 3 years ]
    Associations of molecular and immune measures with PFS will be summarized descriptively by stratified Kaplan-Meier curves and, if numbers permit, by proportional hazards models with molecular and immune responses as predictors. Will assess whether one arm has superior PFS, using proportional hazards models to control for clinical covariates.


Other Outcome Measures:
  1. Changes in PD-L1 expression assessed by immunohistochemistry and immunofluorescence [ Time Frame: Baseline up to 3 years ]
    Standard descriptive and graphical methods will be used to summarize the baseline levels and post-treatment changes for comparison, which will allow us to examine whether observed patterns are consistent with hypothesized mechanisms. The quantitative immune studies will be compared using a t-test to further inform the decision. Multiplicity of testing will not be considered since this considered an exploratory analysis. Association with response rate will be summarized descriptively by presenting the mean, SD, and other characteristics of molecular and immune measures, stratified by response s

  2. Functional assessment of tumor infiltrating immune cells assessed by immunophenotyping [ Time Frame: Baseline up to 3 years ]
    Standard descriptive and graphical methods will be used to summarize the baseline levels and post-treatment changes for comparison of the three MEKi and pembrolizumab sequencing schemes, which will allow us to examine whether observed patterns are consistent with hypothesized mechanisms. The quantitative immune studies will be compared using a t-test to further inform the decision. Multiplicity of testing will not be considered since this considered an exploratory analysis. Association with response rate will be summarized descriptively by presenting the mean, SD, and other characteristics of

  3. Local tumor cytokine/chemokine signatures assessed by Luminex [ Time Frame: Baseline up to 3 years ]
    Standard descriptive and graphical methods will be used to summarize the baseline levels and post-treatment changes for comparison of the three MEKi and pembrolizumab sequencing schemes, which will allow us to examine whether observed patterns are consistent with hypothesized mechanisms. The quantitative immune studies will be compared using a t-test to further inform the decision. Multiplicity of testing will not be considered since this considered an exploratory analysis. Association with response rate will be summarized descriptively by presenting the mean, SD, and other characteristics of

  4. MEK target inhibition [ Time Frame: Baseline up to 3 years ]
    Standard descriptive and graphical methods will be used to summarize the baseline levels and post-treatment changes for comparison of the three MEKi and pembrolizumab sequencing schemes, which will allow us to examine whether observed patterns are consistent with hypothesized mechanisms. The quantitative immune studies will be compared using a t-test to further inform the decision. Multiplicity of testing will not be considered since this considered an exploratory analysis. Association with response rate will be summarized descriptively by presenting the mean, SD, and other characteristics of
