Axitinib and Nivolumab in Treating Participants With Unresectable or Metastatic TFE/Translocation Renal Cell Carcinoma

PRIMARY OBJECTIVES:

I. To establish the clinical activity of axitinib and/or nivolumab therapy for advanced
transcription factor E3/translocation morphology renal cell carcinoma (TFE/tRCC).

SECONDARY OBJECTIVES:

I. To further define the toxicities of the study arms in the treatment of translocation
morphology RCC across all ages.

EXPLORATORY OBJECTIVES:

I. To characterize tRCC clinical behavior across all age groups. II. To evaluate type of
antitumor immune response and stability of T cell activation before and after treatment with
immunotherapy or antiangiogenic therapy.

III. To develop a tumor bank of tRCC tumor samples treated on study for further biological
investigations.

OUTLINE: Participants are randomized to 1 of 3 arms.

ARM A: Participants receive axitinib orally (PO) twice daily (BID) on days 1-28 and nivolumab
intravenously (IV) over 30-60 minutes on days 1 and 15. Treatment repeats every 28 days for
up to 26 courses (2 years) in the absence of disease progression or unacceptable toxicity.

ARM B: Participants receive axitinib PO BID on days 1-28. Treatment repeats every 28 days for
up to 26 courses (2 years) in the absence of disease progression or unacceptable toxicity.

ARM C: Participants receive nivolumab IV over 30-60 minutes on days 1 and 15. Treatment
repeats every 28 days for up to 26 courses (2 years) in the absence of disease progression or
unacceptable toxicity.

After completion of study treatment, participants are followed up every 3 months for 1 year,
every 4 months for 1 year, every 6 months for 2 years. Follow-up at year 5 and beyond is at
the discretion of the treating physician.
