Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Pembrolizumab
Treatment: Other - Stereotactic Ablative Radiotherapy
Treatment: Surgery - Nephrectomy

Active comparator: SABR plus nephrectomy - Stereotactic Ablative Radiotherapy (SABR) will be prescribed to a dose of 42Gy in 3 fractions. All radiotherapy treatment be completed within 3 weeks.Patients will undergo nephrectomy within 9-12 weeks after the first dose of treatment.

Experimental: Pembrolizumab followed by SABR after cycle 1 plus nephrectomy - Pembrolizumab 200 mg (flat dose) will be administered as a 30 minute IV infusion every 21 days for 3 cycles. Patients will receive 1 cycle of pembolizumab prior to SABR followed by an additional 2 cycles of pembrolizumab (1 cycle is 21 days). Patients will undergo nephrectomy 9-12 weeks after commencement of treatment.

Eligibility
Key inclusion criteria
1. Patient has provided written informed consent
2. Male or female aged 18 years or older at written informed consent
3. Histologically or cytologically confirmed diagnosis of RCC with clear cell, rhabdoid or sarcomatoid components
4. Tumour stage T1B-T3, N0 or N1, M0 or low volume M1 planned for nephrectomy

* White Blood Cell (WBC) = 3 X 10^9/L
* Absolute neutrophil count (ANC) =1.5 X 10^9/L
* Platelets = 100 X 10^9/L
* Haemoglobin = 100 g/L independent of transfusion
* Serum Creatinine =1.5 X Upper Limit of Normal (ULN) or measured or calculated CrCl calculated as per institutional standard = 30 ml/min. GFR can also be used in place of serum creatinine or CrCl.

WOCBP 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 120 days after the last dose of study medication. Patients of childbearing potential are those who have not been surgically sterilised or have not been free from menses for more than 1 year

Key exclusion criteria
1. Had prior treatment with any anti-PD-1, or anti-PD-L1, or PD-L2 agent or with an antibody targeting any other immune-regulatory receptors or mechanisms. Examples of such antibodies include antibodies against IDO, PD-L1, IL-2R, and GITR
2. Known or active inflammatory bowel disease involving colon and small bowels

6. Has an active autoimmune disease that has required systemic treatment in the last 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (eg., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment and is allowed
7. Has a known additional malignancy that is progressing or has required active treatment in the last 2 years Note: Basal cell carcinoma of the skin, squamous cell carcinoma of the skin, superficial bladder cancer, or carcinoma in situ, such as breast cancer in situ, that has undergone potentially curative therapy are not excluded
8. Has known active CNS metastases and/or carcinomatous meningitis. Patients with previously treated brain metastases may participate provided they are radiologically stable, i.e. without evidence of progression for at least 4 weeks by repeat imaging (note that the repeat imaging should be performed during study screening), clinically stable and without requirement of steroid treatment for at least 14 days prior to randomisation
9. Has severe hypersensitivity (=Grade 3) to pembrolizumab and/or any of its excipients
10. Has a history of (non-infectious) pneumonitis that required steroids or has current pneumonitis
11. Has an active infection requiring systemic therapy
12. Has a known history of HIV infection
13. Has known history of Hepatitis B (defined as Hepatitis B surface antigen [HBsAg] reactive)or known active Hepatitis C (defined as HCV RNA [qualitative] is detected) infection
14. Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the patient's participation for the full duration of the study, or is not in the best interest of the patient to participate, in the opinion of the treating investigator
15. Has a known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial
16. Has received a live virus vaccine within 30 days prior to randomisation. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette-Guérin (BCG), and typhoid vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (eg, FluMist®) are live attenuated vaccines and are not allowed
17. Has had a prior solid organ transplant
18. Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the study, starting with the screening visit through 120 days after the last dose of study drug.
19. Any contraindications for surgery
