Summary

The purpose of this study is to investigate the safety and feasibility of administering investigational drugs (meaning not Food and Drug Administration (FDA)-approved for kidney cancer) prior to surgical treatment for kidney cancer. The first drug is called MEDI4736, and the second drug is called tremelimumab. Both of these drugs work by attaching to certain proteins on immune cells with the goal of stimulating an immune response against cancer cells. This is a phase 1 trial, with the primary goal of identifying if this treatment is safe and possible side effects when given prior to surgery for kidney cancer.

Detailed description

Objectives: Primary Objective • To investigate the safety and feasibility of neoadjuvant plus adjuvant dosing of durvalumab +/- tremelimumab in patients with localized renal cell carcinoma (RCC). Secondary Objectives * To assess the immune response to neoadjuvant plus adjuvant dosing of durvalumab +/- tremelimumab in patients with localized RCC as measured an increased density of tumor-infiltrating CD8 T-cells. * To assess the antitumor effect of neoadjuvant durvalumab +/- tremelimumab in patients with RCC as measured by change in tumor size. Correlative Objectives * To explore pharmacodynamic and microbiome markers of response to checkpoint inhibition in pre- and post-treatment blood and tissue samples (e.g. infiltration of T cells, T regulatory cells and/or Myeloid-derived suppressor cells). * To understand changes in the immunological milieu mediated by pre-surgical immune checkpoint blockade (e.g. change in T cell repertoire, expression of T cell agonist targets). Study Design: This study will be a single-arm open-label phase Ib study of neoadjuvant durvalumab +/- tremelimumab in localized / locally advanced, non-metastatic RCC patients suitable for nephrectomy. Upon selection as appropriate for study, patients will undergo computed tomography (CT)-guided biopsy of renal mass to obtain histological confirmation of diagnosis, and immunologic characterization of the RCC tumor. Peripheral blood will also be drawn at time of screening. Patients will subsequently receive systemic neoadjuvant treatment in one of 5 cohorts as defined below. Following systemic therapy, patients will undergo nephrectomy. Type of surgery (open vs. minimally invasive, radical vs. partial) and template for lymph node dissection are at the discretion of surgeon. Timing of surgery in relation to adverse events and/or treatment for adverse events from neoadjuvant dosing of study drugs is at the discretion of the surgeon. Adjuvant therapy will be administered within 4-6 weeks of surgery. Subsequent follow-up will then be completed to assess adverse event resolution and long-term outcomes.
