Summary
This phase II trial studies how well pembrolizumab with or without standard of care axitinib works in treating patients with clear cell kidney cancer that has spread to nearby tissues or lymph nodes (locally advanced) or other places in the body (metastatic) who are undergoing surgery. Pembrolizumab is an antibody that is designed to bind to and block the activity of PD-1, a molecule in the body that may be responsible for inhibiting the body's immune response against cancer cells. Axitinib is a type of drug known as a tyrosine kinase inhibitor. Tyrosine kinase inhibitors work by blocking enzymes called tyrosine kinases. These enzymes may be too active or found at high levels in some types of cancer cells and blocking them may help keep cancer cells from growing. Giving pembrolizumab with or without axitinib may work better in controlling the cancer and decrease the likelihood of it coming back following surgery in patients with kidney cancer compared to usual treatment (surgery followed by chemotherapy and/or radiation therapy).

institutional ULN (within 10 days of treatment initiation)

ULN (within 10 days of treatment initiation)

- Albumin >= 2.5 mg/dL (within 10 days of treatment initiation)

- International normalized ratio (INR) or prothrombin time (PT) =< 1.5 x ULN unless
subject is receiving anticoagulant therapy as long as PT or activated partial
thromboplastin time (aPTT) is within therapeutic range of intended use of
anticoagulants (within 10 days of treatment initiation)

- Activated partial thromboplastin time (aPTT) =< 1.5 x ULN unless subject is receiving
anticoagulant therapy as long as PT or aPTT is within therapeutic range of intended
use of anticoagulants (within 10 days of treatment initiation)

- Negative urine or serum pregnancy test within 72 hours prior to receiving the first
dose of study medication (day 1) (female participants of childbearing potential). If
the urine test is positive or cannot be confirmed as negative, a serum pregnancy test
will be required

- Male and female participants 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
