  • Not pregnant and not nursing, because this study involves an investigational agent whose genotoxic, mutagenic and teratogenic effects on the developing fetus and newborn are unknown
  • Therefore, for women of childbearing potential only, a negative pregnancy test done =< 14 days prior to registration is required
  • Age >= 18 years
  • Eastern Cooperative Oncology Group (ECOG) performance status =< 2 or Karnofsky >= 60%

  • Creatinine =< 1.5 x upper limit of normal (ULN) OR creatinine clearance >= 40 mL/min

  • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 3.0 x ULN
  • Alkaline (alk) phosphatase (phos) =< 3.0 x ULN
  • No active, known or suspected autoimmune disease except for vitiligo, type I diabetes mellitus, residual hypothyroidism due to autoimmune condition only requiring hormone replacement, psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger
  • No active systemic infection requiring therapy, as well as positive tests for hepatitis B surface antigen or hepatitis C antibody

  • STEP 2 ELIGIBILITY CRITERIA: Completion of at least 1 cycle of treatment and not have an unresolved adverse event that would preclude surgery
  • STEP 2 ELIGIBILITY CRITERIA: No evidence of progression that would preclude resection
  • STEP 2 ELIGIBILITY CRITERIA: ECOG performance status =< 2 or Karnofsky >= 60%

You cannot join if

  • No patients deemed to be unresectable or poor surgical candidates

The treatment

How it is intended to work

This is how the treatment is meant to work. Whether it helps, and how safe it is, is what this trial is testing.

The study

Treatment groups

Na · Single Group · masking: None

Treatment (nivolumab, ipilimumab, surgery) (Experimental)

Patients receive nivolumab IV, ipilimumab IV, and may undergo surgery on study. Patients also undergo CT or MRI and PET throughout the trial.

What it involves

Procedures
