• Participant gender: All

Summary

This study aims to evaluate the safety, tolerability and effectiveness of new treatments for kidney cancer called Nivolumab and Ipilimumab. The study is in two parts; in the first instance patients receive nivolumab alone. If this treatment is not effective patients may move onto the second part of the trial, where they receive nivolumab + ipilimumab. There is no placebo.

The reason to offer one treatment alone, followed by two treatments together is that it is thought that the double treatment may have more side-effects, but also may be effective in people in whom the single first treatment (nivolumab alone) has not helped.

Nivolumab and ipilimumab are experimental treatments. This means that they are not an approved treatment for non-clear cell kidney cancer in Australia.

The purpose of this study is to test the effectiveness, safety, and tolerability of Nivolumab (also known as Opdivo or BMS-936558) and Ipilumumab (also known as MDX-010 or Yervoy). Nivolumab and ipilimumab are antibodies (a type of human protein) that are being tested to see if they will allow the body's immune system to work against tumour cells. The immune system is the body's defence against cancer, bacteria and viruses. The effectiveness of nivolumab and ipilimumab in cancer of the kidney will be assessed by measuring the size of patient tumours via CT scans.

Nivolumab and ipilimumab have been used alone or in combination in many other cancers, and are licenced for use in other cancers like advanced melanoma and bladder cancer in Australia. They have not been tested in people with non-clear cell kidney cancer.

About 85 participants with non-clear cell kidney cancer are expected to participate in this study, from Australia and New Zealand.

This research study has been initiated by Dr. Craig Gedye, is being conducted in collaboration with the Centre for Biostatistics and Clinical Trials (BaCT) and sponsored in Australia by the Australian and New Zealand Urogenital and Prostate (ANZUP) Cancer Trials Group Pty Ltd. Bristol Myers Squibb (BMS) is supplying the study drugs and grant funding for this research.

4. Eastern Cooperative Oncology Group (ECOG) performance status of 0-1

5. Adequate bone marrow function (should be performed within 14 days prior to registration and with values within the ranges specified below):

• Haemoglobin ≥ 90g/L

• Platelets ≥ 100x109/L

• Neutrophil count ≥ 1.5x109/L

6. Adequate liver function (should be performed within 14 days prior to registration and with values within the ranges specified below):

• Bilirubin ≤ 1.5 x upper limit of normal (ULN) except for participants with known Gilbert's syndrome who can have total bilirubin < 3.0 mg/dL

• AST or ALT ≤ 3.0 x ULN (or ≤ 5.0x ULN in the presence of liver metastases)

7. Adequate renal function (should be performed within 14 days prior to registration and with values within the ranges specified below):

• Creatinine ≤ 1.5x ULN OR

• Creatinine clearance (CrCl) ≥ 30mL/min (use Cockcroft-Gault Formula)

8. Female participants of childbearing potential should have a negative urine or serum pregnancy within 24 hours prior to registering the patient. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.

9. Female participants of childbearing potential should be willing to use two methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through to 5 months after the last dose of study medication. Participants of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year.

10. Male participants should agree to use an adequate method of contraception starting with the first dose of study therapy through to 7 months after the last dose of study therapy.

11. Able to provide a formalin-fixed paraffin embedded (FFPE) tumour block, representative of the participant's primary or metastatic disease (preferred), which must be forwarded to the Centre for Biostatistics and Clinical Trials (BaCT) within 10 working days post registration

12. Willing and able to start treatment within 14 days of registration, and to comply with all study requirements, including the timing and/or nature of the required treatment and assessments

13. Has provided signed, written informed consent.

Exclusion Criteria:

1. Urothelial or transitional cell carcinoma of the renal pelvis or ureter

2. Predominant clear cell renal cell carcinoma. A minority of clear cell histology (<50%) is acceptable, but there must be >50% non-clear cell histology predominant.

3. Participation in a study of an investigational agent within 30 days of registration.

4. Prior treatment with nivolumab, ipilimumab, or with any other anti-PD-1, anti-PD-L1, Anti-PD-L2, anti-CTLA-4 antibody or any other antibody or drug specifically targeting T cell co-stimulation or immune checkpoint pathways (NB Participant is eligible for Part 2 of the study if they took nivolumab monotherapy in Part 1 of the study).

5. Active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs).

6. Any condition requiring systemic treatment with either corticosteroids (>10mg daily prednisone or equivalent dose of alternative corticosteroid) or other immunosuppressive medications within 14 days of registration.
