Brief summary

This phase I/II trial studies the side effects and best dose of entinostat when given together with aldesleukin and to see how well this works in treating patients with kidney cancer that has spread to other places in the body. Entinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Aldesleukin may stimulate the white blood cells to kill kidney cancer cells. Giving entinostat together with aldesleukin may be a better treatment for metastatic kidney cancer.

Detailed description

PRIMARY OBJECTIVES: I. To evaluate the safety and tolerability of high dose interleukin 2 (aldesleukin) in combination with entinostat in patients with metastatic renal cell carcinoma (RCC). (Phase I) II. To monitor toxicity and estimate the efficacy of high dose aldesleukin combined with entinostat in patients with metastatic RCC. (Phase II) SECONDARY OBJECTIVES: I. To compare the time-to-tumor progression, progression-free survival and overall survival of patients with metastatic RCC treated with high dose aldesleukin combined with entinostat to the historical data of patients treated with high dose aldesleukin alone. (Phase II) II. To assess the toxicity of high dose aldesleukin combined with entinostat. (Phase II) III. To evaluate entinostat pharmacodynamics (PD) in blood and tumor samples. (Phase II) IV. To measure the association between baseline laboratory parameters (e.g. cluster of differentiation \[CD\]4+, CD8+, CD4+/forkhead box P3 \[Foxp3\]), tumor blood metabolism, and a variety of response variables (e.g. toxicity, response and survival). (Phase II) V. To explore the relationship between entinostat exposure with PD endpoints (e.g. toxicity and histone acetylation in peripheral blood mononuclear cells or peripheral blood mononuclear cells \[PBMNCs\] and changes in T cell subset population). (Phase II) VI. To evaluate the modulation of tumor metabolism by fluorodeoxyglucose (FDG, fludeoxyglucose F 18) positron emission tomography (PET)/computed tomography (CT) scan. (Phase II) OUTLINE: This is a phase I, dose-escalation study of entinostat followed by a phase II study. Patients receive entinostat orally (PO) every 2 weeks beginning on day -14 and high-dose aldesleukin intravenously (IV) every 8 hours on days 1-5 and 15-19. Cycles repeat every 84 days\* in the absence of disease progression or unacceptable toxicity. NOTE: \*Patients with evidence of tumor shrinkage may receive up to 3 cycles of high-dose aldesleukin therapy. Patients with stable disease by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.0 criteria, but without evidence of tumor shrinkage after two cycles will receive only entinostat until disease progression is documented. After completion of study treatment, patients are followed up at 30 days and then every 3 months thereafter.
