About

Single arm, open label, phase II trial. Participants to undergo biopsy of primary tumour followed by 8 weeks of nivolumab therapy followed by nephrectomy. Nivolumab to be continued post-operatively

Full description

Renal cell carcinoma (RCC) is diagnosed in around 8500 patients annually in the UK. Approximately one third of these patients present with metastatic disease where the RCC has spread to other organs. The mainstay of treatment for these patients is systemic drug therapy, but surgery to remove the primary kidney tumour (i.e. nephrectomy) may also provide clinical benefit.

There is no standard preoperative systemic drug therapy in metastatic RCC, but such preoperative therapy is used widely in the treatment of other cancer types. This approach has several potential advantages including shrinking the tumour to help improve surgical outcomes and to aid identification of appropriate postoperative Drug therapy.

Over the last 10 years several agents have demonstrated promising activity in RCC including the monoclonal antibody therapy nivolumab. This novel immunotherapy works by blocking an immune cell receptor (programmed death1(PD1)) which the cancer can otherwise utilise to evade an individuals immune system attack. This study will investigate the use of nivolumab therapy as a preoperative treatment in patients with metastatic RCC for whom nephrectomy is planned. A total of 19 patients will be recruited at the Royal Marsden Hospital Patients will be treated with nivolumab for 8 weeks prior to surgery, after which nivolumab therapy will restart and continue until such time that the patient is not receiving an overall clinical benefit.

The primary aim of the study will be to assess the safety of such a strategy, with further aims to assess clinical effectiveness. This is also a unique opportunity to further investigate the way in which nivolumab works and to identify predictors of treatment response. To achieve this patients will be asked to provide biopsy samples of their RCC pre & post nivolumab treatment and their nephrectomy tissue for research use, alongside additional blood & urine samples.

15. Prothrombin time (PT) ≤1.5 x ULN
16. Signed and dated informed consent document indicating that the patient (or legally acceptable representative) has been informed of all pertinent aspects of the trial prior to enrollment
17. Willingness and ability to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures

Exclusion criteria

1. Intracranial disease, unless there has been radiological evidence of stable intracranial disease > 6 months.
2. Need for nephrectomy to relieve symptoms relating to the primary tumour or for emergency nephrectomy
3. History of severe hypersensitivity reaction to other monoclonal antibodies
4. Prior malignancy, active within the last 3 years, except for locally curable cancers which have been apparently cured
5. Known HIV or AIDS-related illness
6. Any active, known or suspected autoimmune disease or any condition requiring systemic treatment with either corticosteroids or other immunosuppressive medications within 14 days of study drug administration. Inhaled or topical steroids and physiological replacement doses >10mg daily prednisolone equivalent are permitted in the absence of active autoimmune disease.
7. Active infection requiring therapy
8. Positive tests for Hepatitis B surface antigen or Hepatitis C ribonucleic acid (RNA) indicating acute or chronic infection
9. Pregnancy or breastfeeding. Female patients must be surgically sterile or be postmenopausal, or must agree to use effective contraception during the period of therapy and for 26 weeks following the last dose of study drug. All female patients with childbearing potential must have a negative pregnancy test (serum or urine) prior to enrolment/nivolumab treatment. Male patients must be surgically sterile or must agree to use effective contraception during the period of therapy and for 31 weeks after the last dose of study drug. Women who are not of childbearing potential and azoospermic men do not require contraception.
10. Current signs or symptoms of severe progressive or uncontrolled hepatic, haematologic, gastrointestinal, endocrine, pulmonary or cardiac disease other than directly related to RCC
11. Use of vaccines against infectious diseases (eg influenza, varicella) within 28 days of initiation of study therapy
