30-40% of patients with initially localised Renal Cell Carcinoma (RCC) develop metastatic disease despite optimal surgical excision. To date, results of adjuvant tyrosine-kinase inhibitor trials have been inconclusive, and the current global standard‑of‑care after nephrectomy remains active monitoring. Checkpoint inhibitors are effective in metastatic RCC. RAMPART will investigate checkpoint inhibitors in the adjuvant setting.


RAMPART is an investigator-initiated, international, randomised phase III trial of adjuvant checkpoint inhibitors in patients with resected RCC. The target population is patients with histologically proven RCC (clear cell and non-clear cell), with no residual macroscopic disease, and who are at high or intermediate risk of relapse (Leibovich score 3-11). Participants are randomly assigned (3:2:2) to Arm A - active monitoring (no placebo) for one year, Arm B - durvalumab (PD-L1 inhibitor) 4-weekly for one year; or Arm C - combination therapy with durvalumab 4-weekly for one year plus two doses of tremelimumab (CTLA4 inhibitor). The co-primary outcomes are disease-free survival and overall survival. Secondary outcomes include metastasis-free survival, RCC specific survival, quality of life, preferences, and adverse events. Tumour tissue, blood and urine are collected for analysis (TransRAMPART). RAMPART is an innovative multi-arm multi-stage platform trial, upon which additional research questions may be addressed over time. 


We randomised the first patient in October 2018. By May 2019, we recruited 47 of our target 1750 patients from 24 UK sites, averaging 9 patients per month.  We will open in additional UK sites and imminently in France, Australia and USA.


RAMPART is an international, UK-led trial for RCC at intermediate and high risk of recurrence after surgical excision. The full support of our UK and international collaborators is essential to meet our ambitious accrual target and complete this important trial aimed at optimising adjuvant treatment for renal cancer patients.
