- Objective Response Rate (ORR) [ Time Frame: Up to 1 year ]For participants receiving at least one dose of study treatment, the ORR is defined as the best overall response recorded from the start of the treatment until disease progression or recurrence as assessed over a 1-year period from the start of treatment. The frequency and percentages of patients with a best overall response rate of complete response (CR), partial response (PR), stable disease (SD), or progressive disease (PD) will be determined. We will test the hypothesis that the ORR is greater than the null hypothesis of 10% using the Fisher's exact test.
- Duration of Response (DR) [ Time Frame: Up to 4 years ]The DR for Complete Response (CR) and Partial Response (PR) will be measured from the date that the best response is first recorded until the date that PD is documented. For patients who continue treatment post progression, the date of Disease Progression (PD) documentation will be used for analysis. The DR will be summarized using descriptive statistics (N, mean, standard deviation, minimum, and maximum).
- Disease Control Rate (DCR) According to RECIST Version 1.1 Criteria. [ Time Frame: Up to 4 years ]DCR will be defined as the percentage of patients who have achieved CR, PR, or SD for at least 12 weeks. The DCR will be summarized using descriptive statistics (N, mean, standard deviation, minimum, and maximum).
- Progression Free Survival (PFS) According to RECIST Version 1.1 Criteria. [ Time Frame: Up to 1 year ]PFS will be calculated as 1+ the number of days from the first dose of study drugs to documented radiographic progression or death due to any cause over a period of 1 year. For patients who continue treatment post-progression, the date of radiographic progression will be used for PFS analysis. For patients who continue treatment post-progression, the date of radiographic progression will be used for PFS analysis. The Kaplan-Meier analysis will be used to calculate the median PFS with 95% confidence interval.
- Overall Survival (OS) [ Time Frame: Up to 1 year ]OS will be calculated as 1+ the number of days from the first dose of study drugs to death due to any cause over a period of 1 year. The Kaplan-Meier analysis will be used to calculate the median OS with 95% confidence interval.

- Received at least one prior line of cancer therapy for the treatment of NSCLC; this should include at least one of the following: platinum (carboplatin or cisplatin) doublet chemotherapy (acceptable combinations include: paclitaxel, docetaxel, abraxane, pemetrexed, gemcitabine, vinorelbine, or etoposide), anti-PD1/PDL1 therapy (pembrolizumab, nivolumab, or atezolizumab), or appropriate targeted therapy in patients with activating EGFR (osimertinib, erlotinib, gefitinib, or afatinib), ALK (alectinib, crizotinib, ceritinib, brigatinib, or loralatinib), or ROS-1 (crizotininb or entrectinib) alterations; therapy may be given as monotherapy or in combination with other cancer therapy (e.g. bevacizumab, ipilumimab)
- Patients with a known activating mutation in epidermal growth factor receptor (EGFR) (Exon 19 deletion, G719A, S768I, V769L, T790M, L833F, L858R, L861Q), must have progressed or been intolerant to treatment with a first-line EGFR tyrosine kinase inhibitor (TKI) (erlotinib, afatinib, or gefitinib). Patients whose tumors were found to have an EGFR T790M mutation must also have progressed or been intolerable to treatment with osimertinib.
- Patients with a known Anaplastic lymphoma kinase (ALK)-rearrangement must have progressed or been intolerant to treatment with at least one ALK TKI: crizotinib ceritinib, alectinib,brigatinib, or loralatinib
- Patients with a known ROS-1-rearrangement must have progressed or been intolerant to treatment with crizotinib or entrectinib
- Patients with PDL1 level of >= 50%, who do not have an ALK-rearrangement or EGFR-mutation, must have progressed or been intolerant to treatment with anti-PD1/PDL1 therapy (pembrolizumab, nivolumab, or atezolizumab)

- Women of childbearing potential must have a negative serum or urine pregnancy test within 3 days prior to study enrollment. The effects of trametinib on the developing human fetus are unknown. For this reason and because animal studies with trametinib have shown reproductive toxicity, women of child-bearing potential and men must agree to use effective methods of contraception (hormonal or barrier method of birth control) prior to study entry, for the duration of study participation, and for 4 months following discontinuation of trametinib. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of study drug administration.

- Pregnant women are excluded from this study; breastfeeding should be discontinued if the mother is treated with trametinib . Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with trametinib, breastfeeding should be discontinued if the mother is treated with trametinib.
