A Study to Compare Treatments for a Type of Kidney Cancer Called TFE/Translocation Renal Cell Carcinoma (tRCC)

Study Overview
=================
Brief Summary
-----------------
This phase II trial studies how well axitinib and nivolumab work in treating patients with TFE/translocation renal cell carcinoma that cannot be removed by surgery (unresectable) or has spread to other places in the body (metastatic). Axitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving axitinib and nivolumab may work better in treating patients with TFE/translocation renal cell carcinoma compared to standard treatment, including surgery, chemotherapy, or immunotherapy.

Detailed Description
-----------------
PRIMARY OBJECTIVE: I. To establish the clinical activity, assessed primarily by progression-free survival, of nivolumab therapy with or without axitinib for advanced transcription factor E3/translocation morphology renal cell carcinoma (TFE/tRCC). SECONDARY OBJECTIVE: 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. IV. To characterize the pharmacokinetics of axitinib when given in combination with nivolumab in pediatric patients with tRCC. OUTLINE: Patients are now randomized to 1 of 2 arms - Arm A or Arm C. ARM A: Patients receive axitinib orally (PO) twice daily (BID) on days 1-28 and nivolumab intravenously (IV) over 30 minutes, or per institutional guidelines, on days 1 and 15 (if < 18 years old) or on day 1 (if >= 18 years old). Treatment repeats every 28 days for up to 26 cycles (2 years) in the absence of disease progression or unacceptable toxicity. ARM B: Patients receive axitinib PO BID on days 1-28. Treatment repeats every 28 days for up to 26 cycles (2 years) in the absence of disease progression or unacceptable toxicity. (CLOSED TO ACCRUAL AS OF 1/23/2020 - PROSPECTIVE PATIENTS ARE RANDOMLY ASSIGNED TO ARMS A OR C) ARM C: Patients receive nivolumab IV over 30 minutes, or per institutional guidelines, on days 1 and 15 (if < 18 years old) or on day 1 (if >= 18 years old). Treatment repeats every 28 days for up to 26 cycles (2 years) in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months for 1 year, every 4 months for 1 year, and every 6 months for 2 years. Follow-up at year 5 and beyond is at the discretion of the treating physician.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Progression free survival |  | From randomization to the earliest of disease progression (according to Response Evaluation Criteria in Solid Tumors adapted for immunotherapy) or death due to any cause, assessed up to 4 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Overall survival | A stratified, one-sided log-rank test (using the stratification factors at randomization, age and prior therapy) will be performed to compare treatment arms with alpha = 0.05. Cox proportional hazards models will also be fit to evaluate the final hazard ratio between the treatment arms, with exploratory modeling taking into account the potential influence of other factors (e.g., baseline disease burden, upfront versus delayed nephrectomy). From these models, the hazard ratio for treatment assignment will be reported with a 90% confidence interval (to align with the overall alpha level of the primary log-rank test). | From randomization to death due to any cause, assessed up to 4 years | 
| Overall response rate (ORR) | Will be defined as the rate of complete or partial responses (assessed by imaging) among patients who initiated protocol therapy and completed at least one subsequent imaging assessment. A logistic regression model for overall response, stratified by the stratification factors used at randomization (age and prior therapy) will be fit, including treatment arm as a key covariate. From this model, the odds ratio for treatment arm will be reported with a 90% confidence interval. The ORR observed within each treatment arm will also be reported. | Up to 4 years | 
| Incidence of adverse events (AEs) | All grade 3 non-hematologic toxicities and all grade 4-5 or higher adverse events occurring during protocol therapy or within 30 days of treatment discontinuation will be analyzed. The rates of these events will be reported separately by treatment arm with 95% exact confidence intervals, both by individual AE and class of AE (e.g., hematologic). Given that some AEs may be rare, Fisher Exact tests will be used to test for statistical significance among any apparent differences by treatment arm. | Within 30 days of treatment discontinuation |
