Basic Information

• Recruitment Status: COMPLETED

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.

Detailed Description

PRIMARY OBJECTIVES:

I. To evaluate the safety and tolerability of pembrolizumab (MK-3475) when given in combination with trametinib in the proposed sequencing schemes in patients with advanced or metastatic non-small cell lung cancer with KRAS mutations.

SECONDARY OBJECTIVES:

To assess in a preliminary manner the clinical efficacy of these combinations with the proposed sequencing schemes including overall response rate and progression free survival.

TERTIARY OBJECTIVES:

To determine in an exploratory manner changes in PD-L1 expression as well as other immune correlates induced by mitogen-activated extracellular signal-regulated kinase (MEK) inhibition.

Conditions

KRAS Gene Mutation; Metastatic Non-Squamous Non-Small Cell Lung Carcinoma; Recurrent Non-Squamous Non-Small Cell Lung Carcinoma; Stage IV Non-Small Cell Lung Cancer AJCC v7

Eligibility Criteria

Inclusion Criteria

• Female subject of childbearing potential should have a negative urine or serum pregnancy test within 72 hours prior to receiving the first dose of study medication; if the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
• Female subjects of childbearing potential must be willing to use an adequate method of contraception for the course of the study through 120 days after the last dose of study medication; note: abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject
• Male subjects of childbearing potential must agree to use an adequate method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy; note: abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject
• Clarification: subjects with atrial fibrillation controlled for > 30 days prior to dosing are eligible
