This is a phase 2 study whose main purpose is to evaluate gene changes and immune biomarkers in patients with solid tumors during treatment with pembrolizumab and in relation to response to treatment.
Pembrolizumab is a monoclonal antibody that is designed to block a protein called programmed cell death 1 ligand 1 (PD-L1) which will allow the body's immune system to kill the cancer cells.

|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||100 participants|
|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Official Title:||Investigator-initiated Phase II Study of Pembrolizumab Immunological Response Evaluation|
|Actual Study Start Date :||March 21, 2016|

|Estimated Study Completion Date :||August 2021|
Pembrolizumab will be given by intravenous infusion (IV, given by vein) at a dose of 200 mg, once every 3 weeks.
Pembrolizumab is a potent and highly selective humanized monoclonal antibody (mAb) of the IgG4/kappa isotype designed to directly block the interaction between PD-1 and its ligands, PD-L1 and PD-L2.
- Changes in genomic and immune biomarkers that will be measured in blood and tumor pre-treatment, on-treatment and at progression (progression biopsies only done for those who have complete or partial responses, or stable disease for more than 4 months) [ Time Frame: 5 years ]T-test or Wilcoxon's test
- Overall response rate [ Time Frame: 5 years ]
- Changes in circulating tumor DNA genomic biomarkers [ Time Frame: 5 years ]
- Changes in radiomic imaging parameters [ Time Frame: 5 years ]
- Correlation between tumor genomic profiles and radiomic imaging signatures [ Time Frame: 5 years ]
- Changes in immune cell subsets in the blood and tumor microenvironment [ Time Frame: 5 years ]
- Positive predictive value and negative predictive value of in vitro predictive assay for Pembrolizumab response [ Time Frame: 5 years ]
- Distribution of drug tumor penetration using a mass spectrometry assay [ Time Frame: 5 years ]
- Baseline tumor RNA expression profile for immune inhibitory genes [ Time Frame: 5 years ]
- Comparison of baseline tumor RNA expression profile for immune inhibitory genes with clinical outcome (response) [ Time Frame: 5 years ]
