Clinical Trial Summary

This study will examine the effect of treatment with the neoadjuvant antibody pembrolizumab (MK-3475) on tumors of participants with renal cell cancer (RCC). The primary hypotheses are that pembrolizumab is well tolerated in participants undergoing RCC tumor resection; and that pembrolizumab will stimulate a 2-fold or greater increase in intratumoral lymphocytic infiltration in at least 30% of participants with RCC.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With an Adverse Event (AE) During the Neoadjuvant Pembrolizumab Regimen	An AE was defined as any untoward medical occurrence in a participant administered study treatment and which did not necessarily have to have a causal relationship with this treatment. The number of participants who experienced an AE during their regimen of neoadjuvant pembrolizumab was presented.	Up to Week 16
Primary	Number of Participants Who Discontinued Treatment Due to an Adverse Event	An AE was defined as any untoward medical occurrence in a participant administered study treatment and which did not necessarily have to have a causal relationship with this treatment. The number of participants who discontinued study drug due to an adverse event is presented.	Up to 56 weeks
Primary	Number of Participants Treated With Neoadjuvant Pembrolizumab With a 2-fold or Greater Change From Baseline in Intratumoral CD3+ Lymphocytic Infiltration	The number of participants who received neoadjuvant pembrolizumab and showed a 2-fold or greater change from baseline in intratumoral CD3+ lymphocytic infiltration is presented. Evaluations were based on pathologist score.	Baseline and Week 7
Primary	Number of Participants Treated With Neoadjuvant Pembrolizumab With a 2-fold or Greater Change From Baseline in Intratumoral CD8+ Lymphocytic Infiltration	The number of participants who received neoadjuvant pembrolizumab and showed a 2-fold or greater change from baseline in intratumoral CD8+ lymphocytic infiltration is presented. Evaluations were based on pathologist score.	Baseline and Week 7
Primary	Number of Participants Treated With Neoadjuvant Pembrolizumab With a 2-fold or Greater Change From Baseline in Intratumoral FoxP3+ Lymphocytic Infiltration	The number of participants who received neoadjuvant pembrolizumab and showed a 2-fold or greater change from baseline in intratumoral FoxP3+ (forkhead box protein P3 positive) lymphocytic infiltration is presented. Evaluations were based on pathologist score.	Baseline and Week 7
Secondary	Change From Baseline in Levels of Gene Expression of Immune Modulatory Receptors in Tumors of Participants Treated With Neoadjuvant Pembrolizumab	The change from baseline in levels of gene expression of immune modulatory receptors in tumors of participants treated with neoadjuvant pembrolizumab was presented.	Baseline and Week 7
Secondary	Change From Baseline in Number of T Cells in Tumors of Participants Treated With Neoadjuvant Pembrolizumab	The change from baseline in number of T cells in tumors of participants treated with neoadjuvant pembrolizumab was presented.	Baseline and Week 7
Secondary	Change From Baseline in Number of Activated T Cells in Peripheral Blood of Participants Treated With Neoadjuvant Pembrolizumab	The change from baseline in the number of activated T cells in peripheral blood of participants treated with neoadjuvant pembrolizumab was presented.	Baseline and Week 7
